Use this typesafe pattern with poison pills:

            if (this == o) return true;
            if (o == null || getClass() != o.getClass()) return false;
            ValidMessage<?> that = (ValidMessage<?>) o;
            return value.equals(that.value);

}

To add to Jason's answer:

You can speed the process up (which might be helpful for very large exponents) using the binary expansion of the exponent. First calculate 5, 5^2, 5^4, 5^8 mod 221 - you do this by repeated squaring:

 5^1 = 5(mod 221)
 5^2 = 5^2 (mod 221) = 25(mod 221)
 5^4 = (5^2)^2 = 25^2(mod 221) = 625 (mod 221) = 183(mod221)
 5^8 = (5^4)^2 = 183^2(mod 221) = 33489 (mod 221) = 118(mod 221)
5^16 = (5^8)^2 = 118^2(mod 221) = 13924 (mod 221) = 1(mod 221)
5^32 = (5^16)^2 = 1^2(mod 221) = 1(mod 221)

Now we can write

55 = 1 + 2 + 4 + 16 + 32

so 5^55 = 5^1 * 5^2 * 5^4 * 5^16 * 5^32 
        = 5   * 25  * 625 * 1    * 1 (mod 221)
        = 125 * 625 (mod 221)
        = 125 * 183 (mod 183) - because 625 = 183 (mod 221)
        = 22875 ( mod 221)
        = 112 (mod 221)

You can see how for very large exponents this will be much faster (I believe it's log as opposed to linear in b, but not certain.)

Old post but this is exactly what I needed, simple question, how to change it to count column rather than Row. Thankyou in advance. Novice to Excel.

=SUM(A1:INDIRECT(CONCATENATE("A",C5)))

I.e My data is A1 B1 C1 D1 etc rather then A1 A2 A3 A4.

Here's another one:

people = []
1.times do
  info = gets.chomp
  unless info.empty? 
    people += [Person.new(info)]
    redo
  end
end

As mentioned in other answers, you'll always get the QuotaExceededError in Safari Private Browser Mode on both iOS and OS X when localStorage.setItem (or sessionStorage.setItem) is called.

One solution is to do a try/catch or Modernizr check in each instance of using setItem.

However if you want a shim that simply globally stops this error being thrown, to prevent the rest of your JavaScript from breaking, you can use this:

https://gist.github.com/philfreo/68ea3cd980d72383c951

// Safari, in Private Browsing Mode, looks like it supports localStorage but all calls to setItem
// throw QuotaExceededError. We're going to detect this and just silently drop any calls to setItem
// to avoid the entire page breaking, without having to do a check at each usage of Storage.
if (typeof localStorage === 'object') {
    try {
        localStorage.setItem('localStorage', 1);
        localStorage.removeItem('localStorage');
    } catch (e) {
        Storage.prototype._setItem = Storage.prototype.setItem;
        Storage.prototype.setItem = function() {};
        alert('Your web browser does not support storing settings locally. In Safari, the most common cause of this is using "Private Browsing Mode". Some settings may not save or some features may not work properly for you.');
    }
}

This does not answer the question fully, but for anyone who is able to calculate the number of days by which they would like to offset an initial date then the following method will work:

myDate.setUTCDate(myDate.getUTCDate() + offsetDays);

offsetDays can be positive or negative and the result will be correct for any given initial date with any given offset.

Somewhere, you need to tell Apache that people are allowed to see contents of this directory.

<Directory "F:/bar/public">
    Order Allow,Deny
    Allow from All
    # Any other directory-specific stuff
</Directory>

That header doesn't exist in standard C++. It was part of some pre-1990s compilers, but it is certainly not part of C++.

Use #include <iostream> instead. And all the library classes are in the std:: namespace, for ex­am­ple std::cout.

Also, throw away any book or notes that mention the thing you said.

The Host Header tells the webserver which virtual host to use (if set up). You can even have the same virtual host using several aliases (= domains and wildcard-domains). In this case, you still have the possibility to read that header manually in your web app if you want to provide different behavior based on different domains addressed. This is possible because in your webserver you can (and if I'm not mistaken you must) set up one vhost to be the default host. This default vhost is used whenever the host header does not match any of the configured virtual hosts.

That means: You get it right, although saying "multiple hosts" may be somewhat misleading: The host (the addressed machine) is the same, what really gets resolved to the IP address are different domain names (including subdomains) that are also referred to as hostnames (but not hosts!).

Although not part of the question, a fun fact: This specification led to problems with SSL in early days because the web server has to deliver the certificate that corresponds to the domain the client has addressed. However, in order to know what certificate to use, the webserver should have known the addressed hostname in advance. But because the client sends that information only over the encrypted channel (which means: after the certificate has already been sent), the server had to assume you browsed the default host. That meant one ssl-secured domain per IP address / port-combination.

This has been overcome with Server Name Indication; however, that again breaks some privacy, as the server name is now transferred in plain text again, so every man-in-the-middle would see which hostname you are trying to connect to.

Although the webserver would know the hostname from Server Name Indication, the Host header is not obsolete, because the Server Name Indication information is only used within the TLS handshake. With an unsecured connection, there is no Server Name Indication at all, so the Host header is still valid (and necessary).

Another fun fact: Most webservers (if not all) reject your HTTP request if it does not contain exactly one Host header, even if it could be omitted because there is only the default vhost configured. That means the minimum required information in an http-(get-)request is the first line containing METHOD RESOURCE and PROTOCOL VERSION and at least the Host header, like this:

GET /someresource.html HTTP/1.1
Host: www.example.com

In the MDN Documentation on the "Host" header they actually phrase it like this:

A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.

As mentioned by Darrel Miller, the complete specs can be found in RFC7230.

I think token should be handled just like password. As such, they should be encrypted in DB.

I'n doing something like this to generate a unique new token for a model:

key = ActiveSupport::KeyGenerator
                .new(Devise.secret_key)
                .generate_key("put some random or the name of the key")

loop do
  raw = SecureRandom.urlsafe_base64(nil, false)
  enc = OpenSSL::HMAC.hexdigest('SHA256', key, raw)

  break [raw, enc] unless Model.exist?(token: enc)
end

Try enclosing your date into a character string.

 select * 
 from dbo.March2010 A
 where A.Date >= '2010-04-01';

With python 3 you can use list_a[filter] to get True values. To get False values use list_a[~filter]

That isn't the Node.js command prompt window. That is a language shell to run JavaScript commands, also known as a REPL.

In Windows, there should be a Node.js command prompt in your Start menu or start screen:

Which will open a command prompt window that looks like this:

From there you can switch directories using the cd command.

@keyframes rotate {
    100% {
        transform: rotate(1turn);
    }
}

div{
   animation: rotate 4s linear infinite;
}

I was the only developer in the team experiencing this same issue, it worked perfectly for everybody so I realized it had to be my environment. I tried a git clone of the same project in another directory and it compiled perfectly, then I realized it had to be Xcode caching stuff for my project path somewhere, that "somewhere" is the DerivedData folder, just remove it and do a clean build of your project, it worked for me.

You can get the path and even open the folder in finder by going to:

Xcode -> Preferences -> Locations -> **DerivedData

/Users/{user}/Library/Application Support/Sublime Text 2/Packages

Get to it quickly from within Sublime via the menu at Sublime Text 2... Preferences... Browse Packages

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

The previous answer is fine, but I'm one of those guys that's firmly against mixing behavior with presentation (putting JavaScript in my HTML) so I prefer to put my event handling logic in my JavaScript files. Additionally, not all browsers implement event (or e) the same way. You may want to do a check prior to running any logic:

document.onkeydown = TabExample;

function TabExample(evt) {
  var evt = (evt) ? evt : ((event) ? event : null);
  var tabKey = 9;
  if(evt.keyCode == tabKey) {
    // do work
  }
}

Dherik : I'm not sure about what you say, when you don't use fetch the result will be of type : List<Object[ ]> which means a list of Object tables and not a list of Employee.

Object[0] refers an Employee entity 
Object[1] refers a Departement entity 

When you use fetch, there is just one select and the result is the list of Employee List<Employee> containing the list of departements. It overrides the lazy declaration of the entity.

If you know Array's length but you don't know its content, you can use

val length = 5
val temp = Array.ofDim[String](length)

If you want to have two dimensions array but you don't know its content, you can use

val row = 5
val column = 3
val temp = Array.ofDim[String](row, column)

Of course, you can change String to other type.

If you already know its content, you can use

val temp = Array("a", "b")

Here's the correct way of doing it:

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK)
    {
        Uri imageUri = data.getData();
        Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
    }
}

If you need to load very large images, the following code will load it in in tiles (avoiding large memory allocations):

BitmapRegionDecoder decoder = BitmapRegionDecoder.newInstance(myStream, false);  
Bitmap region = decoder.decodeRegion(new Rect(10, 10, 50, 50), null);

This is a part from a REST-Service I´ve written recently.

var select = $("#productSelect")
for (var prop in data) {
    var option = document.createElement('option');
    option.innerHTML = data[prop].ProduktName
    option.value = data[prop].ProduktName;
    select.append(option)
}

The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.

I ran into this today (mysql 2.16.0) and thought I'd share my solution:

const items = [
    {name: 'alpha', description: 'describes alpha', value: 1},
    ...
];

db.query(
    'INSERT INTO my_table (name, description, value) VALUES ?',
    [items.map(item => [item.name, item.description, item.value])],
    (error, results) => {...}
);

I re-installed node through this link and it fixed it.

I think the issue was that I somehow got node to be in my /usr/bin instead of /usr/local/bin.

In iOS this worked fine for me

CGFloat height = self.inputTableView.contentSize.height;
if (height > CGRectGetHeight(self.inputTableView.frame)) {
    height -= (CGRectGetHeight(self.inputTableView.frame) - CGRectGetHeight(self.navigationController.navigationBar.frame));
}
else {
    height = 0;
}
[self.inputTableView setContentOffset:CGPointMake(0, height) animated:animated];

It needs to be called from viewDidLayoutSubviews

You want to pass the function object hi to your loop() function, not the result of a call to hi() (which is None since hi() doesn't return anything).

So try this:

>>> loop(hi, 5)
hi
hi
hi
hi
hi

Perhaps this will help you understand better:

>>> print hi()
hi
None
>>> print hi
<function hi at 0x0000000002422648>

This is not an answer, really and I would have entered it as a comment had the question not been locked. This answers the question:

Why would you want it?

Assume you have a table with the sequence as the primary key and the sequence is generated by an insert trigger. If you wanted to have the sequence available for subsequent updates to the record, you need to have a way to extract that value.

In order to make sure you get the right one, you might want to wrap the INSERT and RonK's query in a transaction.

RonK's Query:

select MY_SEQ_NAME.currval from DUAL;

In the above scenario, RonK's caveat does not apply since the insert and update would happen in the same session.

For the sake of clarity and stupidity.

1) Open .vscode/settings.json.

2) Add "typescript.tsdk": "node_modules/typescript/lib" on it.

3) Save it.

4) Restart Visual Studio Code.

Looks like older answers were fine for older Jackson versions, but since objectMapper has method setTimeZone(tz), setting time zone on a dateFormat is totally ignored.

How to properly setup timeZone to the ObjectMapper in Jackson version 2.11.0:

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setTimeZone(TimeZone.getTimeZone("Europe/Warsaw"));

Full example

  @Test
  void test() throws Exception {
    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.findAndRegisterModules();
    objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
    JavaTimeModule module = new JavaTimeModule();
    objectMapper.registerModule(module);
    objectMapper.setTimeZone(TimeZone.getTimeZone("Europe/Warsaw"));

    ZonedDateTime now = ZonedDateTime.now();
    String converted = objectMapper.writeValueAsString(now);

    ZonedDateTime restored = objectMapper.readValue(converted, ZonedDateTime.class);
    System.out.println("serialized: " + now);
    System.out.println("converted: " + converted);
    System.out.println("restored: " + restored);

    Assertions.assertThat(now).isEqualTo(restored);
  }
`

I have not tried this, so I am not guarantueeing anything, however

foreach Bar f in filterBars
{
     search(f)
}
Foo search(Bar b)
{
    fooSelect = (from f in fooBunch
                 where !(from b in f.BarList select b.BarId).Contains(b.ID)
                 select f).ToList();

    return fooSelect;
}

I followed the solution by poke with a minor adjustment in the end. My steps follow
- git fetch --prune;
- git branch -a printing the following
    master
    branch
    remotes/origin/HEAD -> origin/master
    remotes/origin/master
    remotes/origin/branch (remote branch to remove)
- git push origin --delete branch.
Here, the branch to remove is not named as remotes/origin/branch but simply branch. And the branch is removed.

OAuth is an open standard for authorization, commonly used as a way for Internet users to log into third party websites using their Microsoft, Google, Facebook or Twitter accounts without exposing their password.

You could use the 'isActive' prop like so:

const { router } = this.context;
if (router.isActive('/login')) {
    router.push('/');
}

isActive will return a true or false.

Tested with react-router 2.7

Try this on a call. I sometimes use it in onClick of a button.

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

It instead of closing your app , opens the dashboard so kind of looks like your app is closed.

I would do the following:

public class Book
{
    private final String title;
    private final String isbn;

    public Book(final String t, final String i)
    {
        if(t == null)
        {
            throw new IllegalArgumentException("t cannot be null");
        }

        if(i == null)
        {
            throw new IllegalArgumentException("i cannot be null");
        }

        title = t;
        isbn  = i;
    }
}

I am making the assumption here that:

1) the title will never change (hence title is final) 2) the isbn will never change (hence isbn is final) 3) that it is not valid to have a book without both a title and an isbn.

Consider a Student class:

public class Student
{
    private final StudentID id;
    private String firstName;
    private String lastName;

    public Student(final StudentID i,
                   final String    first,
                   final String    last)
    {
        if(i == null)
        {
            throw new IllegalArgumentException("i cannot be null"); 
        }

        if(first == null)
        {
            throw new IllegalArgumentException("first cannot be null"); 
        }

        if(last == null)
        {
            throw new IllegalArgumentException("last cannot be null"); 
        }

        id        = i;
        firstName = first;
        lastName  = last;
    }
}

There a Student must be created with an id, a first name, and a last name. The student ID can never change, but a persons last and first name can change (get married, changes name due to losing a bet, etc...).

When deciding what constrructors to have you really need to think about what makes sense to have. All to often people add set/get methods because they are taught to - but very often it is a bad idea.

Immutable classes are much better to have (that is classes with final variables) over mutable ones. This book: http://books.google.com/books?id=ZZOiqZQIbRMC&pg=PA97&sig=JgnunNhNb8MYDcx60Kq4IyHUC58#PPP1,M1 (Effective Java) has a good discussion on immutability. Look at items 12 and 13.

You can find the ObjectId constructor on require('mongoose').Types. Here is an example:

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId();

id is a newly generated ObjectId.

You can read more about the Types object at Mongoose#Types documentation.

I am on macOS and I had used brew but what Vaulstein mentioned in his answer didn't cover my case.

I run the following commands to make sure my current python was not installed by brew

brew list | grep python           
python
python@2

brew info python
[email protected]: stable 3.8.3 (bottled)
Interpreted, interactive, object-oriented programming language
https://www.python.org/
Not installed
... 

So I download the latest 3.8.5 from https://www.python.org/ and when installing it I saw following information

Certificate verification and OpenSSL

This package includes its own private copy of OpenSSL 1.1.1. The trust certificates in system and user keychains managed by the Keychain Access application and the security command line utility are not used as defaults by the Python ssl module

After installed 3.8.5 it fixed the problem.

Using Java 8 streams:

double sum = m.stream()
    .mapToDouble(a -> a)
    .sum();

System.out.println(sum); 

The call

e.extractAll("th")

for a regular method extractAll() is indeed equivalent to

Extractor.extractAll(e, "th")

These two calls are treated the same in all regards, including the error messages you get.

If you don't need to pass the instance to a method, you can use a staticmethod:

@staticmethod
def extractAll(tag):
    ...

which can be called as e.extractAll("th"). But I wonder why this is a method on a class at all if you don't need to access any instance.

The simplest way is using python-dateutil

import datetime

import dateutil

def birthday(date):
    # Get the current date
    now = datetime.datetime.utcnow()
    now = now.date()

    # Get the difference between the current date and the birthday
    age = dateutil.relativedelta.relativedelta(now, date)
    age = age.years

    return age

I will give a simple example of how OOP should be done in C. I realise this thead is from 2009 but would like to add this anyway.

/// Object.h
typedef struct Object {
    uuid_t uuid;
} Object;

int Object_init(Object *self);
uuid_t Object_get_uuid(Object *self);
int Object_clean(Object *self);

/// Person.h
typedef struct Person {
    Object obj;
    char *name;
} Person;

int Person_init(Person *self, char *name);
int Person_greet(Person *self);
int Person_clean(Person *self);

/// Object.c
#include "object.h"

int Object_init(Object *self)
{
    self->uuid = uuid_new();

    return 0;
}
uuid_t Object_get_uuid(Object *self)
{ // Don't actually create getters in C...
    return self->uuid;
}
int Object_clean(Object *self)
{
    uuid_free(self->uuid);

    return 0;
}

/// Person.c
#include "person.h"

int Person_init(Person *self, char *name)
{
    Object_init(&self->obj); // Or just Object_init(&self);
    self->name = strdup(name);

    return 0;
}
int Person_greet(Person *self)
{
    printf("Hello, %s", self->name);

    return 0;
}
int Person_clean(Person *self)
{
    free(self->name);
    Object_clean(self);

    return 0;
}

/// main.c
int main(void)
{
    Person p;

    Person_init(&p, "John");
    Person_greet(&p);
    Object_get_uuid(&p); // Inherited function
    Person_clean(&p);

    return 0;
}

The basic concept involves placing the 'inherited class' at the top of the struct. This way, accessing the first 4 bytes in the struct also accesses the first 4 bytes in the 'inherited class' (Asuming non-crazy optimalisations). Now, when the pointer of the struct is cast to the 'inherited class', the 'inherited class' can access the 'inherited values' in the same way it would access it's members normally.

This and some naming conventions for constructors, destructors, allocation and deallocarion functions (I recommend init, clean, new, free) will get you a long way.

As for Virtual functions, use function pointers in the struct, possibly with Class_func(...); wrapper too. As for (simple) templates, add a size_t parameter to determine size, require a void* pointer, or require a 'class' type with just the functionality you care about. (e.g. int GetUUID(Object *self); GetUUID(&p);)

The above-mentioned responses work well but if you want to pass data between 2 sibling components, then the event bus can also be used. Check out this blog which would help you understand better.

supppose for 2 components : CompA & CompB having same parent and main.js for setting up main vue app. For passing data from CompA to CompB without involving parent component you can do the following.

in main.js file, declare a separate global Vue instance, that will be event bus.

export const bus = new Vue();

In CompA, where the event is generated : you have to emit the event to bus.

methods: {
      somethingHappened (){
          bus.$emit('changedSomething', 'new data');
      }
  }

Now the task is to listen the emitted event, so, in CompB, you can listen like.

created (){
    bus.$on('changedSomething', (newData) => {
      console.log(newData);
    })
  }

Advantages:

• Less & Clean code.
• Parent should not involve in passing down data from 1 child comp to another ( as the number of children grows, it will become hard to maintain )
• Follows pub-sub approach.

Look at the File javadoc, the method createNewFile will create the file only if it doesn't exist, and will return a boolean to say if the file was created.

You may also use the exists() method:

int i = 0;
String filename = Integer.toString(i);
File f = new File(filename);
while (f.exists()) {
    i++;
    filename = Integer.toString(i);
    f = new File(filename);
}
f.createNewFile();
System.out.println("File in use: " + f);

Note: if you are trying to get this information for tables that are in a different SCHEMA use the all_tab_columns view, we have this problem as our Applications use a different SCHEMA for security purposes.

use the following:

EG:

SELECT
    data_length 
FROM
    all_tab_columns 
WHERE
    upper(table_name) = 'MY_TABLE_NAME' AND upper(column_name) = 'MY_COL_NAME'

First, I wouldn't use document.body. Instead add an empty container:

index.html:

<html>
    <head></head>
    <body>
        <div id="app"></div>
    </body>
</html>

Then opt to only render your <App /> element:

main.js:

var App = require('./App.js');
ReactDOM.render(<App />, document.getElementById('app'));

Within App.js you can import your other components and ignore your DOM render code completely:

App.js:

var SampleComponent = require('./SampleComponent.js');

var App = React.createClass({
    render: function() {
        return (
            <div>
                <h1>App main component!</h1>
                <SampleComponent name="SomeName" />
            </div>
        );
    }
});

SampleComponent.js:

var SampleComponent = React.createClass({
    render: function() {
        return (
            <div>
                <h1>Sample Component!</h1>
            </div>
        );
    }
});

Then you can programmatically interact with any number of components by importing them into the necessary component files using require.

For me, the solution given on the page maven is not able to download anything from central because ssl don't work worked, when running Mint 19 in a VM:

sudo apt install ca-certificates-java
sudo update-ca-certificates -f

You can return FileResult with this methods:

1: Return FileStreamResult

    [HttpGet("get-file-stream/{id}"]
    public async Task<FileStreamResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var stream = await GetFileStreamById(id);

        return new FileStreamResult(stream, mimeType)
        {
            FileDownloadName = fileName
        };
    }

2: Return FileContentResult

    [HttpGet("get-file-content/{id}"]
    public async Task<FileContentResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var fileBytes = await GetFileBytesById(id);

        return new FileContentResult(fileBytes, mimeType)
        {
            FileDownloadName = fileName
        };
    }

Stick with the present tense imperative because

• it's good to have a standard
• it matches tickets in the bug tracker which naturally have the form "implement something", "fix something", or "test something."

You can use the $set syntax if you want to set the value of a document to an arbitrary value. This will either update the value if the attribute already exists on the document or create it if it doesn't. If you need to set a single value in a dictionary like you describe, you can use the dot notation to access child values.

If p is the object retrieved:

existing = p['d']['a']

For pymongo versions < 3.0

db.ProductData.update({
  '_id': p['_id']
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False, multi=False)

For pymongo versions >= 3.0

db.ProductData.update_one({
  '_id': p['_id']
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False)

However if you just need to increment the value, this approach could introduce issues when multiple requests could be running concurrently. Instead you should use the $inc syntax:

For pymongo versions < 3.0:

db.ProductData.update({
  '_id': p['_id']
},{
  '$inc': {
    'd.a': 1
  }
}, upsert=False, multi=False)

For pymongo versions >= 3.0:

db.ProductData.update_one({
  '_id': p['_id']
},{
  '$inc': {
    'd.a': 1
  }
}, upsert=False)

This ensures your increments will always happen.

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

One of the easiest solutions is using the following protocol:

protocol ScrollViewKeyboardDelegate: class {
    var scrollView: UIScrollView? { get set }

    func registerKeyboardNotifications()
    func unregisterKeyboardNotifications()
}

extension ScrollViewKeyboardDelegate where Self: UIViewController {
    func registerKeyboardNotifications() {
        NotificationCenter.default.addObserver(
            forName: UIResponder.keyboardWillChangeFrameNotification,
            object: nil,
            queue: nil) { [weak self] notification in
                self?.keyboardWillBeShown(notification)
        }

        NotificationCenter.default.addObserver(
            forName: UIResponder.keyboardWillHideNotification,
            object: nil,
            queue: nil) { [weak self] notification in
                self?.keyboardWillBeHidden(notification)
        }
    }

    func unregisterKeyboardNotifications() {
        NotificationCenter.default.removeObserver(
            self,
            name: UIResponder.keyboardWillChangeFrameNotification,
            object: nil
        )
        NotificationCenter.default.removeObserver(
            self,
            name: UIResponder.keyboardWillHideNotification,
            object: nil
        )
    }

    func keyboardWillBeShown(_ notification: Notification) {
        let info = notification.userInfo
        let key = (info?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)
        let aKeyboardSize = key?.cgRectValue

        guard let keyboardSize = aKeyboardSize,
            let scrollView = self.scrollView else {
                return
        }

        let bottomInset = keyboardSize.height
        scrollView.contentInset.bottom = bottomInset
        scrollView.scrollIndicatorInsets.bottom = bottomInset
        if let activeField = self.view.firstResponder {
            let yPosition = activeField.frame.origin.y - bottomInset
            if yPosition > 0 {
                let scrollPoint = CGPoint(x: 0, y: yPosition)
                scrollView.setContentOffset(scrollPoint, animated: true)
            }
        }
    }

    func keyboardWillBeHidden(_ notification: Notification) {
        self.scrollView?.contentInset = .zero
        self.scrollView?.scrollIndicatorInsets = .zero
    }
}

extension UIView {
    var firstResponder: UIView? {
        guard !isFirstResponder else { return self }
        return subviews.first(where: {$0.firstResponder != nil })
    }
}

When you want to use this protocol, you only need to conform to it and assign your scroll view in your controller as follows:

class MyViewController: UIViewController {
      @IBOutlet var scrollViewOutlet: UIScrollView?
      var scrollView: UIScrollView?

      public override func viewDidLoad() {
        super.viewDidLoad()

        self.scrollView = self.scrollViewOutlet
        self.scrollView?.isScrollEnabled = true
        self.registerKeyboardNotifications()
    }

    extension MyViewController: ScrollViewKeyboardDelegate {}

    deinit {
       self.unregisterKeyboardNotifications()
    }

}

I know its too late now. However even today if you are having trouble accessing cross thread controls? This is the shortest answer till date :P

Invoke(new Action(() =>
                {
                    label1.Text = "WooHoo!!!";
                }));

This is how i access any form control from a thread.

You must create a new anonymous type:

 select new { op, pg }

Refer to the official guide.

For git 1.9.5 on Windows 7: "my Notes" (double quotes) corrected this issue. In my case putting the file(s) before or after the -m 'message'. made no difference; using single quotes was the problem.

Given the implementation of indexOf for IE (as described by eyelidlessness):

Array.prototype.contains = function(obj) {
    return this.indexOf(obj) > -1;
};

It is because there is no package cache in the image, you need to run:

apt-get update

before installing packages, and if your command is in a Dockerfile, you'll then need:

apt-get -y install curl

To suppress the standard output from a command use -qq. E.g.

apt-get -qq -y install curl

Goto .idea/modules.xml & delete the invalid/not existing path <module />. Then File => Invalidate Caches / Restart.

I wanted a more permanent and quicker way. Because I tend to forget to add extra lines before writing my actual Update/Insert queries.

I did it by checking SET IMPLICIT_TRANSACTIONS check-box from Options. To navigate to Options Select Tools>Options>Query Execution>SQL Server>ANSI in your Microsoft SQL Server Management Studio.

Just make sure to execute commit or rollback after you are done executing your queries. Otherwise, the table you would have run the query will be locked for others.

You can use the default traceroute command for this purpose, then there will be nothing to install.

traceroute -T -p 9100 <IP address/hostname>

The -T argument is required so that the TCP protocol is used instead of UDP.

In the rare case when traceroute isn't available, you can also use ncat.

nc -Czvw 5 <IP address/hostname> 9100

This function will return true if it's Date or false otherwise:

function isDate(myDate) {
    return myDate.constructor.toString().indexOf("Date") > -1;
} 

From the jQuery documentation:

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().

I haven’t actually done anything with font-face, so take this with a pinch of salt, but I don’t think there’s any way for the browser to definitively tell if a given web font installed on a user’s machine or not.

The user could, for example, have a different font with the same name installed on their machine. The only way to definitively tell would be to compare the font files to see if they’re identical. And the browser couldn’t do that without downloading your web font first.

Does Firefox download the font when you actually use it in a font declaration? (e.g. h1 { font: 'DejaVu Serif';)?

You need to change public void klik(PaintEventArgs pea, EventArgs e) to public void klik(object sender, System.EventArgs e) because there is no Click event handler with parameters PaintEventArgs pea, EventArgs e.

Actually it depends on what shell you use, however most shells have similar bindings. The bindings you are referring to (e.g. Ctrl+A and Ctrl+E) are bindings you will find in many other programs and they are used for ages, BTW also work in most UI apps.

Here's a look of default bindings for Bash:

Most Important Bash Keyboard Shortcuts

Please also note that you can customize them. You need to create a file, name as you wish, I named mine .bash_key_bindings and put it into my home directory. There you can set some general bash options and you can also set key bindings. To make sure they are applied, you need to modify a file named ".bashrc" that bash reads in upon start-up (you must create it, if it does not exist) and make the following call there:

bind -f ~/.bash_key_bindings

~ means home directory in bash, as stated above, you can name the file as you like and also place it where you like as long as you feed the right path+name to bind.

Let me show you some excerpts of my .bash_key_bindings file:

set meta-flag on
set input-meta on
set output-meta on
set convert-meta off
set show-all-if-ambiguous on
set bell-style none
set print-completions-horizontally off

These just set a couple of options (e.g. disable the bell; this can be all looked up on the bash webpage).

"A": self-insert
"B": self-insert
"C": self-insert
"D": self-insert
"E": self-insert
"F": self-insert
"G": self-insert
"H": self-insert
"I": self-insert
"J": self-insert

These make sure that the characters alone just do nothing but making sure the character is "typed" (they insert themselves on the shell).

"\C-dW": kill-word
"\C-dL": kill-line
"\C-dw": backward-kill-word
"\C-dl": backward-kill-line
"\C-da": kill-line

This is quite interesting. If I hit Ctrl+D alone (I selected d for delete), nothing happens. But if I then type a lower case w, the word to the left of the cursor is deleted. If I type an upper case, however, the word to the right of the cursor is killed. Same goes for l and L regarding the whole line starting from the cursor. If I type an "a", the whole line is actually deleted (everything before and after the cursor).

I placed jumping one word forward on Ctrl+F and one word backward on Ctrl+B

"\C-f": forward-word
"\C-b": backward-word

As you can see, you can make a shortcut, that leads to an action immediately, or you can make one, that just inits a character sequence and then you have to type one (or more) characters to cause an action to take place as shown in the example further above.

So if you are not happy with the default bindings, feel free to customize them as you like. Here's a link to the bash manual for more information.

To Create SQL server Store procedure in SQL server management studio

• Expand your database
• Expand programmatically
• Right-click on Stored-procedure and Select "new Stored Procedure"

Now, Write your Store procedure, for example, it can be something like below

USE DatabaseName;  
GO  
CREATE PROCEDURE ProcedureName 
 @LastName nvarchar(50),   
 @FirstName nvarchar(50)   
AS   

SET NOCOUNT ON;  
 
//Your SQL query here, like
Select  FirstName, LastName, Department  
FROM HumanResources.vEmployeeDepartmentHistory  
WHERE FirstName = @FirstName AND LastName = @LastName  
GO  

Where, DatabaseName = name of your database
ProcedureName = name of SP
InputValue = your input parameter value (@LastName and @FirstName) and type = parameter type example nvarchar(50) etc.

Source: Stored procedure in sql server (With Example)

To Execute the above stored procedure you can use sample query as below

EXECUTE ProcedureName @FirstName = N'Pilar', @LastName = N'Ackerman';  

For accessibility reason, I could not pull it off with multiple type=submit buttons. The only way to work natively with a form with multiple buttons but ONLY one can submit the form when hitting the Enter key is to ensure that only one of them is of type=submit while others are in other type such as type=button. By this way, you can benefit from the better user experience in dealing with a form on a browser in terms of keyboard support.

Most examples on the web (and some presented above) show how to load an XML from a file in a browser compatible manner. This proves easy, except in the case of Google Chrome which does not support the document.implementation.createDocument() method. When using Chrome, in order to load an XML file into a XmlDocument object, you need to use the inbuilt XmlHttp object and then load the file by passing it's URI.

In your case, the scenario is different, because you want to load the XML from a string variable, not a URL. For this requirement however, Chrome supposedly works just like Mozilla (or so I've heard) and supports the parseFromString() method.

Here is a function I use (it's part of the Browser compatibility library I'm currently building):

function LoadXMLString(xmlString)
{
  // ObjectExists checks if the passed parameter is not null.
  // isString (as the name suggests) checks if the type is a valid string.
  if (ObjectExists(xmlString) && isString(xmlString))
  {
    var xDoc;
    // The GetBrowserType function returns a 2-letter code representing
    // ...the type of browser.
    var bType = GetBrowserType();

    switch(bType)
    {
      case "ie":
        // This actually calls into a function that returns a DOMDocument 
        // on the basis of the MSXML version installed.
        // Simplified here for illustration.
        xDoc = new ActiveXObject("MSXML2.DOMDocument")
        xDoc.async = false;
        xDoc.loadXML(xmlString);
        break;
      default:
        var dp = new DOMParser();
        xDoc = dp.parseFromString(xmlString, "text/xml");
        break;
    }
    return xDoc;
  }
  else
    return null;
}

The easiest way to get to know it for your compiler/platform:

#include <iostream>

int main() {
  std::cout << sizeof(long)*8 << std::endl;
}

Themultiplication by 8 is to get bits from bytes.

When you need a particular size, it is often easiest to use one of the predefined types of a library. If that is undesirable, you can do what often happens with autoconf software and have the configuration system determine the right type for the needed size.

Using execComand:

<input type="button" name="save" value="Save" onclick="javascript:document.execCommand('SaveAs','true','your_file.txt')">

In the next link: execCommand

The answer by @AKX works on the command line, but not within a batch file. Within a batch file, you need an extra %, like this:

@echo off
for /R TutorialSteps %%F in (*.py) do echo %%~nF

Simply with command line:

javac MyApp.java
jar -cf myJar.jar MyApp.class

Sure IDEs avoid using command line terminal

Actually we get this error also when we create canvas in javascript as below.

document.createElement('canvas');

Here point to be noted we have to provide argument name correctly as 'canvas' not anything else.

I solved this Issue by enabling virtualization technology from system Settings.

Just followed these steps

• Restart my Computer
• Continuously press Esc and then F10 to enter BIOS setup
• configuration
• Check Virtualization technology

Your system settings may be changed According to your Computer. You can google (how to enable virtualizatino for YOUR_PC_NAME).

I hope it helps.

Erland Sommarskog has maintained the authoritative answer to this question for the last 16 years: Arrays and Lists in SQL Server.

There are at least a dozen ways to pass an array or list to a query; each has their own unique pros and cons.

• Table-Valued Parameters. SQL Server 2008 and higher only, and probably the closest to a universal "best" approach.
• The Iterative Method. Pass a delimited string and loop through it.
• Using the CLR. SQL Server 2005 and higher from .NET languages only.
• XML. Very good for inserting many rows; may be overkill for SELECTs.
• Table of Numbers. Higher performance/complexity than simple iterative method.
• Fixed-length Elements. Fixed length improves speed over the delimited string
• Function of Numbers. Variations of Table of Numbers and fixed-length where the number are generated in a function rather than taken from a table.
• Recursive Common Table Expression (CTE). SQL Server 2005 and higher, still not too complex and higher performance than iterative method.
• Dynamic SQL. Can be slow and has security implications.
• Passing the List as Many Parameters. Tedious and error prone, but simple.
• Really Slow Methods. Methods that uses charindex, patindex or LIKE.

I really can't recommend enough to read the article to learn about the tradeoffs among all these options.

You can do it with a sub-query:

SELECT * FROM (
    SELECT * FROM table ORDER BY id DESC LIMIT 50
) sub
ORDER BY id ASC

This will select the last 50 rows from table, and then order them in ascending order.

If your DataGridView does not have any DataSource the solution does not come by manipulating it.

You will always have an empty row if you have the AllowUserToAddRows property set to true.

Put AllowUserToAddRows = false if you don't need permise this.

You can use plt.subplots_adjust to change the spacing between the subplots Link

subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)

left  = 0.125  # the left side of the subplots of the figure
right = 0.9    # the right side of the subplots of the figure
bottom = 0.1   # the bottom of the subplots of the figure
top = 0.9      # the top of the subplots of the figure
wspace = 0.2   # the amount of width reserved for blank space between subplots
hspace = 0.2   # the amount of height reserved for white space between subplots

Using Linq you have many possibilities, here one without using lambdas:

//assuming list is a List<Customer> or something queryable...
var hasJohn = (from customer in list
         where customer.FirstName == "John"
         select customer).Any();

A single listening port can accept more than one connection simultaneously.

There is a '64K' limit that is often cited, but that is per client per server port, and needs clarifying.

Each TCP/IP packet has basically four fields for addressing. These are:

source_ip source_port destination_ip destination_port
<----- client ------> <--------- server ------------>

Inside the TCP stack, these four fields are used as a compound key to match up packets to connections (e.g. file descriptors).

If a client has many connections to the same port on the same destination, then three of those fields will be the same - only source_port varies to differentiate the different connections. Ports are 16-bit numbers, therefore the maximum number of connections any given client can have to any given host port is 64K.

However, multiple clients can each have up to 64K connections to some server's port, and if the server has multiple ports or either is multi-homed then you can multiply that further.

So the real limit is file descriptors. Each individual socket connection is given a file descriptor, so the limit is really the number of file descriptors that the system has been configured to allow and resources to handle. The maximum limit is typically up over 300K, but is configurable e.g. with sysctl.

The realistic limits being boasted about for normal boxes are around 80K for example single threaded Jabber messaging servers.

The definition of "the number of months in the difference" is subject to a lot of interpretation. :-)

You can get the year, month, and day of month from a JavaScript date object. Depending on what information you're looking for, you can use those to figure out how many months are between two points in time.

For instance, off-the-cuff:

function monthDiff(d1, d2) {
    var months;
    months = (d2.getFullYear() - d1.getFullYear()) * 12;
    months -= d1.getMonth();
    months += d2.getMonth();
    return months <= 0 ? 0 : months;
}

function monthDiff(d1, d2) {_x000D_
    var months;_x000D_
    months = (d2.getFullYear() - d1.getFullYear()) * 12;_x000D_
    months -= d1.getMonth();_x000D_
    months += d2.getMonth();_x000D_
    return months <= 0 ? 0 : months;_x000D_
}_x000D_
_x000D_
function test(d1, d2) {_x000D_
    var diff = monthDiff(d1, d2);_x000D_
    console.log(_x000D_

(Note that month values in JavaScript start with 0 = January.)

Including fractional months in the above is much more complicated, because three days in a typical February is a larger fraction of that month (~10.714%) than three days in August (~9.677%), and of course even February is a moving target depending on whether it's a leap year.

There are also some date and time libraries available for JavaScript that probably make this sort of thing easier.

Note: There used to be a + 1 in the above, here:

months = (d2.getFullYear() - d1.getFullYear()) * 12;
months -= d1.getMonth() + 1;
// --------------------^^^^
months += d2.getMonth();

That's because originally I said:

...this finds out how many full months lie between two dates, not counting partial months (e.g., excluding the month each date is in).

I've removed it for two reasons:

1. Not counting partial months turns out not to be what many (most?) people coming to the answer want, so I thought I should separate them out.

2. It didn't always work even by that definition. :-D (Sorry.)

Try a query like

INSERT INTO NEW_TABLENAME SELECT * FROM OLD_TABLENAME;

According to 'Getting Started With LLVM Core Libraries' book (c):

In fact, the name LLVM might refer to any of the following:

• The LLVM project/infrastructure: This is an umbrella for several projects that, together, form a complete compiler: frontends, backends, optimizers, assemblers, linkers, libc++, compiler-rt, and a JIT engine. The word "LLVM" has this meaning, for example, in the following sentence: "LLVM is comprised of several projects".

• An LLVM-based compiler: This is a compiler built partially or completely with the LLVM infrastructure. For example, a compiler might use LLVM for the frontend and backend but use GCC and GNU system libraries to perform the final link. LLVM has this meaning in the following sentence, for example: "I used LLVM to compile C programs to a MIPS platform".

• LLVM libraries: This is the reusable code portion of the LLVM infrastructure. For example, LLVM has this meaning in the sentence: "My project uses LLVM to generate code through its Just-in-Time compilation framework".

• LLVM core: The optimizations that happen at the intermediate language level and the backend algorithms form the LLVM core where the project started. LLVM has this meaning in the following sentence: "LLVM and Clang are two different projects".

• The LLVM IR: This is the LLVM compiler intermediate representation. LLVM has this meaning when used in sentences such as "I built a frontend that translates my own language to LLVM".

This is an API issue, you won't get this error if using Postman/Fielder to send HTTP requests to API. In case of browsers, for security purpose, they always send OPTIONS request/preflight to API before sending the actual requests (GET/POST/PUT/DELETE). Therefore, in case, the request method is OPTION, not only you need to add "Authorization" into "Access-Control-Allow-Headers", but you need to add "OPTIONS" into "Access-Control-allow-methods" as well. This was how I fixed:

if (context.Request.Method == "OPTIONS")
        {
            context.Response.Headers.Add("Access-Control-Allow-Origin", new[] { (string)context.Request.Headers["Origin"] });
            context.Response.Headers.Add("Access-Control-Allow-Headers", new[] { "Origin, X-Requested-With, Content-Type, Accept, Authorization" });
            context.Response.Headers.Add("Access-Control-Allow-Methods", new[] { "GET, POST, PUT, DELETE, OPTIONS" });
            context.Response.Headers.Add("Access-Control-Allow-Credentials", new[] { "true" });

        }

You can also do ORDER BY TITLE COLLATE NOCASE.

Edit: If you need to specify ASC or DESC, add this after NOCASE like

ORDER BY TITLE COLLATE NOCASE ASC

or

ORDER BY TITLE COLLATE NOCASE DESC

Use the R method packageDescription to get the installed package description and for version just use $Version as:

packageDescription("AppliedPredictiveModeling")$Version

As mentioned in @Bernd Buffen's answer. This is issue with MariaDB 5.5, I simple upgrade MariaDB 5.5 to MariaDB 10.1 and issue resolved.

Here Steps to upgrade MariaDB 5.5 into MariaDB 10.1 at CentOS 7 (64-Bit)

1. Add following lines to MariaDB repo.

   nano /etc/yum.repos.d/mariadb.repo and paste the following lines.

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.1/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

2. Stop MariaDB, if already running service mariadb stop

3. Perform update

   yum update

4. Starting MariaDB & Performing Upgrade

   service mariadb start

   mysql_upgrade

Everything Done.

Check MariaDB version: mysql -V

The simple thing is to put the script below the document, just before your closing </body> tag:

<body>
   <div id="main">
      <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
   </div>
   <script src="app.js"></script>
</body>

app.js file:

var main = new Vue({
    el: '#main',
    data: {
        currentActivity: 'home'
    }
});

I came up with a class factory to support this functionality. Pass in any combination of either fields or classes you want to exclude.

public class GsonFactory {

    public static Gson build(final List<String> fieldExclusions, final List<Class<?>> classExclusions) {
        GsonBuilder b = new GsonBuilder();
        b.addSerializationExclusionStrategy(new ExclusionStrategy() {
            @Override
            public boolean shouldSkipField(FieldAttributes f) {
                return fieldExclusions == null ? false : fieldExclusions.contains(f.getName());
            }

            @Override
            public boolean shouldSkipClass(Class<?> clazz) {
                return classExclusions == null ? false : classExclusions.contains(clazz);
            }
        });
        return b.create();

    }
}

To use, create two lists (each is optional), and create your GSON object:

static {
 List<String> fieldExclusions = new ArrayList<String>();
 fieldExclusions.add("id");
 fieldExclusions.add("provider");
 fieldExclusions.add("products");

 List<Class<?>> classExclusions = new ArrayList<Class<?>>();
 classExclusions.add(Product.class);
 GSON = GsonFactory.build(null, classExclusions);
}

private static final Gson GSON;

public String getSomeJson(){
    List<Provider> list = getEntitiesFromDatabase();
    return GSON.toJson(list);
}

There is no do-while loop in Python.

This is a similar construct, taken from the link above.

 while True:
     do_something()
     if condition():
        break

The simple solution is to put it in an iframe and hope that the user has a plug-in that supports it.

(I don't, the Acrobat plugin has been such a resource hog and source of instability that I make a point to remove it from any browser that it touches).

The complicated, but relative popular solution is to display it in a flash applet.

Try this

sudo -u hdfs hdfs dfsadmin -safemode leave

check status of safemode

sudo -u hdfs hdfs dfsadmin -safemode get

If it is still in safemode ,then one of the reason would be not enough space in your node, you can check your node disk usage using :

df -h

if root partition is full, delete files or add space in your root partition and retry first step.

Actions

ADD_PRODUCT : (context,product) => {
  return Axios.post(uri, product).then((response) => {
    if (response.status === 'success') {  
      context.commit('SET_PRODUCT',response.data.data)
    }
    return response.data
  });
});

Component

this.$store.dispatch('ADD_PRODUCT',data).then((res) => {
  if (res.status === 'success') {
    // write your success actions here....
  } else {
     // write your error actions here...
  }
})

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

Use following line in didFinishLaunchingWithOptions: delegate method:

[NSThread sleepForTimeInterval:5.0];

It will stop splash screen for 5.0 seconds.

Yes you can use CASE

UPDATE table 
SET columnB = CASE fieldA 
        WHEN columnA=1 THEN 'x' 
        WHEN columnA=2 THEN 'y' 
        ELSE 'z' 
      END 
WHERE columnC = 1

In my case, simply re-running brew install yarn fixed the problem.

If you want two classes on one element, do it this way:

<div class="social first"></div>

Reference it in css like so:

.social.first {}

Example:

https://jsfiddle.net/tybro0103/covbtpaq/

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

The method of hiding it by adding "display: none;" to the input didn’t work for me if the form is generated through javascript.

So instead I made them invisible by placing them out of sight:

<input style="width:0;height:0;opacity:0;position:absolute;left:-10000px;overflow:hidden;" type="text" name="fakeusernameremembered"/>
<input style="width:0;height:0;opacity:0;position:absolute;left:-10000px;overflow:hidden;" type="password" name="fakepasswordremembered"/>

Check you have the correct APIS enabled as well.

I tried all of the above, asterisks, domain tlds, forward slashes, backslashes and everything, even in the end only entering one url as a last hope.

All of this did not work and finally I realised that Google also requires that you specify now which API's you want to use (see screenshot)

I did not have ones I needed enabled (for me that was Maps JavaScript API)

Once I enabled it, all worked fine using:

http://www.example.com/*

I hope that helps someone! :)

You need to set both the user-agent and the referer:

 wget  --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0" --referrer  connect.wso2.com http://dist.wso2.org/products/carbon/4.2.0/wso2carbon-4.2.0.zip

I encountered two issues related to the foregoing, when extracting text delimited by \ and /, and found a solution that fits both, other than using new RegExp, which requires \\\\ at the start. These findings are in Chrome and IE11.

The regular expression

/\\(.*)\//g

does not work. I think the // is interpreted as the start of a comment in spite of the escape character. The regular expression (equally valid in my case though not in general)

/\b/\\(.*)\/\b/g

does not work either. I think the second / terminates the regular expression in spite of the escape character.

What does work for me is to represent / as \x2F, which is the hexadecimal representation of /. I think that's more efficient and understandable than using new RegExp, but of course it needs a comment to identify the hex code.

If you have reason to avoid the use of the datetime module, then these functions will work.

def is_leap_year(year):
    """ if year is a leap year return True
        else return False """
    if year % 100 == 0:
        return year % 400 == 0
    return year % 4 == 0

def doy(Y,M,D):
    """ given year, month, day return day of year
        Astronomical Algorithms, Jean Meeus, 2d ed, 1998, chap 7 """
    if is_leap_year(Y):
        K = 1
    else:
        K = 2
    N = int((275 * M) / 9.0) - K * int((M + 9) / 12.0) + D - 30
    return N

def ymd(Y,N):
    """ given year = Y and day of year = N, return year, month, day
        Astronomical Algorithms, Jean Meeus, 2d ed, 1998, chap 7 """    
    if is_leap_year(Y):
        K = 1
    else:
        K = 2
    M = int((9 * (K + N)) / 275.0 + 0.98)
    if N < 32:
        M = 1
    D = N - int((275 * M) / 9.0) + K * int((M + 9) / 12.0) + 30
    return Y, M, D

By chance, is this occurring on a directory using OverlayFS (or some other special file system type)?

I just had this issue where my cross-compiled version of bash would use an internal implementation of getcwd which has issues with OverlayFS. I found information about this here:

It seems that this can be traced to an internal implementation of getcwd() in bash. When cross-compiled, it can't check for getcwd() use of malloc, so it is cautious and sets GETCWD_BROKEN and uses an internal implementation of getcwd(). This internal implementation doesn't seem to work well with OverlayFS.

http://permalink.gmane.org/gmane.linux.embedded.yocto.general/25204

You can configure and rebuild bash with bash_cv_getcwd_malloc=yes (if you're actually building bash and your C library does malloc a getcwd call).

ModRewrite is not the only answer. You could also use Options +MultiViews in .htaccess and then check $_SERVER REQUEST_URI to find everything that is in URL.

$M2_HOMEis used sometimes, for example, to install Takari Extensions for Apache Maven

One way to find $M2_HOME value is to search for mvn:

sudo find / -name "mvn" 2>/dev/null

And, probably it will be: /opt/maven/

Maybe you should type add this to your .bashrc or .zshrc

export PATH="/anaconda3/bin":$PATH

It worked for me.

In an ideal world you'd achieve this simply using the following css

<style type="text/css">

span {
  display: inline-block;
  width: 50px;
}

</style>

This works on all browsers apart from FF2 and below.

Firefox 2 and lower don't support this value. You can use -moz-inline-box, but be aware that it's not the same as inline-block, and it may not work as you expect in some situations.

Quote taken from quirksmode

var url ='www.site.com/index.php#hello';
var type = url.split('#');
var hash = '';
if(type.length > 1)
  hash = type[1];
alert(hash);

Working demo on jsfiddle

Use '›'

› -> single right angle quote. For single left angle quote, use ‹

myList.GroupBy(test => test.id)
      .Select(grp => grp.First());

Edit: as getting this IEnumerable<> into a List<> seems to be a mystery to many people, you can simply write:

var result = myList.GroupBy(test => test.id)
                   .Select(grp => grp.First())
                   .ToList();

But one is often better off working with the IEnumerable rather than IList as the Linq above is lazily evaluated: it doesn't actually do all of the work until the enumerable is iterated. When you call ToList it actually walks the entire enumerable forcing all of the work to be done up front. (And may take a little while if your enumerable is infinitely long.)

The flipside to this advice is that each time you enumerate such an IEnumerable the work to evaluate it has to be done afresh. So you need to decide for each case whether it is better to work with the lazily evaluated IEnumerable or to realize it into a List, Set, Dictionary or whatnot.

Use an AJAX Request on your PHP file, then display the result on your page, without any reloading.

http://api.jquery.com/load/ This is a simple solution if you don't need any POST data.

You may use pip for that without using the network. See in the docs (search for "Install a particular source archive file"). Any of those should work:

pip install relative_path_to_seaborn.tar.gz    
pip install absolute_path_to_seaborn.tar.gz    
pip install file:///absolute_path_to_seaborn.tar.gz    

Or you may uncompress the archive and use setup.py directly with either pip or python:

cd directory_containing_tar.gz
tar -xvzf seaborn-0.10.1.tar.gz
pip install seaborn-0.10.1
python setup.py install

Of course, you should also download required packages and install them the same way before you proceed.

Since Spring 4.2 you can use @EventListener (documentation)

@Component
class MyClassWithEventListeners {

    @EventListener({ContextRefreshedEvent.class})
    void contextRefreshedEvent() {
        System.out.println("a context refreshed event happened");
    }
}

The syntax for an implicit pipe from a shell command into a bash variable is

var=$(command)

or

var=`command`

In your examples, you are piping data to an assignment statement, which does not expect any input.

I had no luck until I installed the 2010 version link here: https://www.microsoft.com/en-us/download/details.aspx?id=13255

I tried installing the 32 bit version, it still errored, so I uninstalled it and installed the 64 bit version and it started working.

In C++ you can use like this:

matrix *p = new matrix;

After that,

delete p; 

json is a built-in module, you don't need to install it with pip.

Login to any other EC2 instance you have that has access to the RDS instance in question and has mysqladmin installed and run

mysqladmin -h <RDS ENDPOINT URL> -P 3306 -u <USER> -p flush-hosts

you will be prompted for your password

The method select accepts a list of column names (string) or expressions (Column) as a parameter. To select columns you can use:

-- column names (strings):

df.select('col_1','col_2','col_3')

-- column objects:

import pyspark.sql.functions as F

df.select(F.col('col_1'), F.col('col_2'), F.col('col_3'))

# or

df.select(df.col_1, df.col_2, df.col_3)

# or

df.select(df['col_1'], df['col_2'], df['col_3'])

-- a list of column names or column objects:

df.select(*['col_1','col_2','col_3'])

#or

df.select(*[F.col('col_1'), F.col('col_2'), F.col('col_3')])

#or 

df.select(*[df.col_1, df.col_2, df.col_3])

The star operator * can be omitted as it's used to keep it consistent with other functions like drop that don't accept a list as a parameter.

You have three possibilites:

1. Regular expression:

    (new RegExp('word')).test(str)
    // or
    /word/.test(str)
   

2. indexOf:

    str.indexOf('word') !== -1
   

3. includes:

    str.includes('word')
   

Regular expressions seem to be faster (at least in Chrome 10).

Performance test - short haystack
Performance test - long haystack

It cannot be said with certainty which method is faster. The differences between the browsers is enormous. While in Chrome 10 indexOf seems to be faster, in Safari 5, indexOf is clearly slower than any other method.

You have to see and try for your self. It depends on your needs. For example a case-insensitive search is way faster with regular expressions.

Update 2018:

Just to save people from running the tests themselves, here are the current results for most common browsers, the percentages indicate performance increase over the next fastest result (which varies between browsers):

Chrome: indexOf (~98% faster) <-- wow
Firefox: cached RegExp (~18% faster)
IE11: cached RegExp(~10% faster)
Edge: indexOf (~18% faster)
Safari: cached RegExp(~0.4% faster)

Note that cached RegExp is: var r = new RegExp('simple'); var c = r.test(str); as opposed to: /simple/.test(str)

This piece of code:

for s in ("fukushima", "123 is a number", ""):
    print s.ljust(20),  s[0].isdigit() if s else False

prints out the following:

fukushima            False
123 is a number      True
                     False

"Subscript out of range" indicates that you've tried to access an element from a collection that doesn't exist. Is there a "Sheet1" in your workbook? If not, you'll need to change that to the name of the worksheet you want to protect.

Run this query and you'll probably get what you're looking for:

SELECT table_schema "DB Name",
        ROUND(SUM(data_length + index_length) / 1024 / 1024, 1) "DB Size in MB" 
FROM information_schema.tables 
GROUP BY table_schema; 

This query comes from the mysql forums, where there are more comprehensive instructions available.

The solution suggested in this answer has been deprecated, and might no longer work.

Taking a look at the source code of OpenPyXL (IterableWorksheet) I've figured out how to get the column and row count from an iterator worksheet:

wb = load_workbook(path, use_iterators=True)
sheet = wb.worksheets[0]

row_count = sheet.get_highest_row() - 1
column_count = letter_to_index(sheet.get_highest_column()) + 1

IterableWorksheet.get_highest_column returns a string with the column letter that you can see in Excel, e.g. "A", "B", "C" etc. Therefore I've also written a function to translate the column letter to a zero based index:

def letter_to_index(letter):
    """Converts a column letter, e.g. "A", "B", "AA", "BC" etc. to a zero based
    column index.

    A becomes 0, B becomes 1, Z becomes 25, AA becomes 26 etc.

    Args:
        letter (str): The column index letter.
    Returns:
        The column index as an integer.
    """
    letter = letter.upper()
    result = 0

    for index, char in enumerate(reversed(letter)):
        # Get the ASCII number of the letter and subtract 64 so that A
        # corresponds to 1.
        num = ord(char) - 64

        # Multiply the number with 26 to the power of `index` to get the correct
        # value of the letter based on it's index in the string.
        final_num = (26 ** index) * num

        result += final_num

    # Subtract 1 from the result to make it zero-based before returning.
    return result - 1

I still haven't figured out how to get the column sizes though, so I've decided to use a fixed-width font and automatically scaled columns in my application.

In PHP7.3 still working...

https://www.php.net/manual/en/language.oop5.visibility.php

If declared using var, the property will be defined as public.

1. Start the Apache Server and MySQL instances from the XAMPP control panel.
2. Now goto to your localhost.
3. Click on user accounts -> Click on Edit privileges -> You will find an option change password just change password as you want click on go. Image are given below
4. If you refresh the page, you will be getting a error message. This is because the phpMyAdmin configuration file is not aware of our newly set root passoword. To do this we have to modify the phpMyAdmin config file.
5. Open terminal window (not mac default terminal please check attached image)
6. Then Run apt-get update in the newly opened terminal.
7. Then run apt-get install nano this will install nano
8. CD to cd ../opt/lampp/phpmyadmin
9. Open and Edit nano config.inc.php and save.

This started as a comment on RGB's solution but I could not fit it in so have converted it to an answer. The inspiration for which is entirely RGB's.

RGB's solution worked for me. However, I wished to note a couple of points which may help others arriving at this post (like me) who are not that familiar which SVG and who may very well have generated their SVG file from a graphics package (as I had).

So to apply RGB's solutions I used:

The CSS

 <style>
    rect.btn {
        stroke:#fff;
        fill:#fff;
        fill-opacity:0;
        stroke-opacity:0;
    }
</style>

The jquery script

<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>   
<script type="text/javascript">
   $("document").ready(function(){
       $(".btn").bind("click", function(event){alert("clicked svg")});
   });
</script>

The HTML to code the inclusion of your pre-existing SVG file in the group tag inside the SVG code.

<div>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <g>
     <image x="0" y="0" width="10" height="10"
     xlink:href="../_public/_icons/booked.svg" width="10px"/>
    <rect class="btn" x="0" y="0" width="10" height="10"/>

  </g>
</svg>
</div>

However, in my case I have several SVG icons which I wish to be clickable and incorporating each of these into the SVG tag was starting to become cumbersome.

So as an alternative approach where I could employ Classes I used jquery.svg. This is probably a shameful application of this plugin which can do all sorts of stuff with SVG's. But it worked using the following code:

<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>       
<script type="text/javascript" src="jquery.svg.min.js"></script>
<script type="text/javascript">
    $("document").ready(function(){
        $(".svgload").bind("click", function(event){alert("clicked svg")});

         for (var i=0; i < 99; i++) {
           $(".svgload:eq(" + i + ")").svg({
              onLoad: function(){
              var svg = $(".svgload:eq(" + i + ")").svg('get');
              svg.load("../_public/_icons/booked.svg", {addTo: true,  changeSize: false});        
              },
              settings: {}}
          ); 
        } 
    });
</script>

where HTML

<div class="svgload" style="width: 10px; height: 10px;"></div>

The advantage to my thinking is that I can use the appropriate class where ever the icons are needed and avoid quite a lot of code in the body of the HTML which aids readability. And I only need to incorporate the pre-existing SVG file once.

Edit: Here is a neater version of the script courtesy of Keith Wood: using .svg's load URL setting.

<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>       
<script type="text/javascript" src="jquery.svg.min.js"></script>
<script type="text/javascript">
    $("document").ready(function(){

      $('.svgload').on('click', function() {
          alert('clicked svg new');
      }).svg({loadURL: '../_public/_icons/booked.svg'});

    });
</script>

You can try using @RequestBodyParam

@RequestMapping(value = "/saveData", headers="Content-Type=application/json", method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<Boolean> saveData(@RequestBodyParam String source,@RequestBodyParam JsonDto json) throws MyException {
    ...
}

ListView uses clear().

But, if you're just doing it for RecyclerView. First you have to clear your RecyclerView.Adapter with notifyItemRangeRemoved(0,size)

Then, only you recyclerView.removeAllViewsInLayout().

which theme you have used in activity add below one line code

for white

<style name="AppTheme.NoActionBar">
      <item name="android:tint">#ffffff</item>
  </style>

or 
 <style name="AppThemeName" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:tint">#ffffff</item>
</style>

for black

   <style name="AppTheme.NoActionBar">
      <item name="android:tint">#000000</item>
  </style>

or 
 <style name="AppThemeName" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:tint">#000000</item>
</style>

You might be an admin doing a one-off push directly into refs/changes/<change_number>.

For example, once a commit without Change-Id landed into Subversion, you pull it out of Subversion using git-svn, and you'd like to archive it as a Gerrit patchset into a Gerrit change.

If so, you can go to project settings page (http://[installation-path]/#/admin/projects/[project-id]) and temporarily change "Require Change-Id in commit message" value to False.

Don't forget to afterwards change it back to Inherit or True!

Instead of using a collector try using findFirst or findAny.

Optional<Person> matchingObject = objects.stream().
    filter(p -> p.email().equals("testemail")).
    findFirst();

This returns an Optional since the list might not contain that object.

If you're sure that the list always contains that person you can call:

Person person = matchingObject.get();

Be careful though! get throws NoSuchElementException if no value is present. Therefore it is strongly advised that you first ensure that the value is present (either with isPresent or better, use ifPresent, map, orElse or any of the other alternatives found in the Optional class).

If you're okay with a null reference if there is no such person, then:

Person person = matchingObject.orElse(null);

If possible, I would try to avoid going with the null reference route though. Other alternatives methods in the Optional class (ifPresent, map etc) can solve many use cases. Where I have found myself using orElse(null) is only when I have existing code that was designed to accept null references in some cases.

Optionals have other useful methods as well. Take a look at Optional javadoc.

The MaxAge of -1 signals that you want the cookie to persist for the duration of the session. You want to set MaxAge to 0 instead.

From the API documentation:

A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

This method take String as a argument and return the Character Array

/**
 * @param sourceString
 *            :String as argument
 * @return CharcterArray
 */
public static Character[] toCharacterArray(String sourceString) {
    char[] charArrays = new char[sourceString.length()];
    charArrays = sourceString.toCharArray();
    Character[] characterArray = new Character[charArrays.length];
    for (int i = 0; i < charArrays.length; i++) {
        characterArray[i] = charArrays[i];
    }
    return characterArray;
}

As of Swift 3, several changes have been made to the syntax.

Here is how you would go about creating a basic button as of Swift 3:

    let button = UIButton(type: UIButtonType.system) as UIButton
    button.frame = CGRect(x: 100, y: 100, width: 100, height: 50)
    button.backgroundColor = UIColor.green
    button.setTitle("Example Button", for: UIControlState.normal)
    self.view.addSubview(button)

Here are the changes that have been made since previous versions of Swift:

let button = UIButton(type: UIButtonType.System) as UIButton

// system no longer capitalised

button.frame = CGRectMake(100, 100, 100, 50)

// CGRectMake has been removed as of Swift 3

button.backgroundColor = UIColor.greenColor()

// greenColor replaced with green

button.setTitle("Example Button", forState: UIControlState.Normal)

// normal is no longer capitalised

self.view.addSubview(button)

I previously had the same issue, but I realized that I didn't include the "app.js" (the main application) inside my main page (index.html). So even when you include all the dependencies required by AngularJS, you might end up with that error in the console. So always make sure to include the necessary files inside your main page and you shouldn't have that issue.

Hope this helps.

Sub SelectAllCellsInSheet(SheetName As String)
    lastCol = Sheets(SheetName).Range("a1").End(xlToRight).Column
    Lastrow = Sheets(SheetName).Cells(1, 1).End(xlDown).Row
    Sheets(SheetName).Range("A2", Sheets(SheetName).Cells(Lastrow, lastCol)).Select
End Sub

To use with ActiveSheet:

Call SelectAllCellsInSheet(ActiveSheet.Name)

the solution: for type entity use option "data" but value is a object. ie:

$em = $this->getDoctrine()->getEntityManager();

->add('sucursal', 'entity', array
(

    'class' => 'TestGeneralBundle:Sucursal',
    'property'=>'descripcion',
    'label' => 'Sucursal',
    'required' => false,
    'data'=>$em->getReference("TestGeneralBundle:Sucursal",3)           

))

Not sure if anyone is having the same responsive issue, but it was just a simple css solution for me.

same example

...  ng-init="isCollapsed = true" ng-click="isCollapsed = !isCollapsed"> ...
...  div collapse="isCollapsed"> ...

with

@media screen and (min-width: 768px) {
    .collapse{
        display: block !important;
    }
}

For efficiency's sake you want to only hit the data once, as Harper does. However you don't want to use rank() because it will give you ties and further you want to group by language rather than order by language. From there you want add an order by clause to distinguish between rows, but you don't want to actually sort the data. To achieve this I would use "order by null" E.g.

count(*) over (group by language order by null)

var nationality = $("#dancerCountry").val(); should work. Are you sure that the element selector is working properly? Perhaps you should try:

var nationality = $('select[name="dancerCountry"]').val();

logical address is address relative to program. It tells how much memory a particular process will take, not tell what will the exact location of the process and this exact location will we generated by using some mapping, and is known as physical address.

You should use the csv module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows([row[2:4] for _ in range(count)])

or, using the itertools module to do the repeating with itertools.repeat():

from itertools import repeat
import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows(repeat(row[2:4], count))

I solved this on 12.10 by installing libssl-dev.

sudo apt-get install libssl-dev

Pointers

• A pointer is a variable that holds a memory address.
• A pointer declaration consists of a base type, an *, and the variable name.
• A pointer can point to any number of variables in lifetime

• A pointer that does not currently point to a valid memory location is given the value null (Which is zero)

  BaseType* ptrBaseType;
  BaseType objBaseType;
  ptrBaseType = &objBaseType;
  

• The & is a unary operator that returns the memory address of its operand.

• Dereferencing operator (*) is used to access the value stored in the variable which pointer points to.

     int nVar = 7;
     int* ptrVar = &nVar;
     int nVar2 = *ptrVar;
  

Reference

• A reference (&) is like an alias to an existing variable.

• A reference (&) is like a constant pointer that is automatically dereferenced.

• It is usually used for function argument lists and function return values.

• A reference must be initialized when it is created.

• Once a reference is initialized to an object, it cannot be changed to refer to another object.

• You cannot have NULL references.

• A const reference can refer to a const int. It is done with a temporary variable with value of the const

  int i = 3;    //integer declaration
  int * pi = &i;    //pi points to the integer i
  int& ri = i;    //ri is refers to integer i – creation of reference and initialization
  

It is very bad style to define external interfaces in .c files. .

You should do this

a.h

    extern void doSomething (int    sig);

a.c

    void doSomething (int    sig)
    {
       ... do stuff 
    }

b.c

#include "a.h"
.....
signal(SIGNAL, doSomething); 

.

Assuming you want the format "(123) 456-7890":

function formatPhoneNumber(phoneNumberString) {
  var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
  var match = cleaned.match(/^(\d{3})(\d{3})(\d{4})$/)
  if (match) {
    return '(' + match[1] + ') ' + match[2] + '-' + match[3]
  }
  return null
}

Here's a version that allows the optional +1 international code:

function formatPhoneNumber(phoneNumberString) {
  var cleaned = ('' + phoneNumberString).replace(/\D/g, '')
  var match = cleaned.match(/^(1|)?(\d{3})(\d{3})(\d{4})$/)
  if (match) {
    var intlCode = (match[1] ? '+1 ' : '')
    return [intlCode, '(', match[2], ') ', match[3], '-', match[4]].join('')
  }
  return null
}
formatPhoneNumber('+12345678900') // => "+1 (234) 567-8900"
formatPhoneNumber('2345678900')   // => "(234) 567-8900"

use implode(',', $array); for output as apple,banana,orange

Or

foreach($array as $key => $value)
{
   echo $key." is ". $value;
}

Here is very simple and short method

<?php
$time_start = microtime(true);
//the loop begin
//some code
//the loop end
$time_end = microtime(true);
$total_time = $time_end - $time_start;
echo $total_time; // or whatever u want to do with the time
?>

The reason is that the compiler has to actually see the definition in order to be able to drop it in in place of the call.

Remember that C and C++ use a very simplistic compilation model, where the compiler always only sees one translation unit at a time. (This fails for export, which is the main reason only one vendor actually implemented it.)

To rename file using refactoring (which also updates all occurrences of name in other scripts):

1. Save changes to file before using refactoring/renaming
2. In Project Explorer view, right-click file to be renamed and select Refactor | Rename -or- select it and go to Refactor | Rename from the Menu Bar. A Rename File dialog will appear.
3. Enter the file's new name.
4. Check the "Update references" box and click Preview.
5. You can scroll through changes using the Select Next / Previous Change scrolling arrows.
6. Press OK to rename file and update all occurrences of the script name in other scripts.

See "PHP Developer User Guide > Tasks > Using Refactoring > Renaming Files".

In Java 8 you can do this with one line of code.

If your method doesn't take any parameters, you can use a method reference:

new Thread(MyClass::doWork).start();

Otherwise, you can call the method in a lambda expression:

new Thread(() -> doWork(someParam)).start();

Doing it in code is is IMO wrong and even more so if you put it into the onCreate. Do it in the manifest and the "system" knows the orientation from the startup of the app. And this type of meta or top level "guidance" SHOULD be in the manifest. If you want to prove it to yourself set a break in the Activity's onCreate. If you do it in code there it will be called twice : it starts up in Portrait mode then is switched to Landscape. This does not happen if you do it in the manifest.

Here is another way...

The HTML:

<table>
<tbody>
       <tr class='clickableRow'>
       <td>Blah Blah</td>
       <td>1234567</td>
       <td>£158,000</td>
        </tr>
</tbody>
</table>

The jQuery:

$(function() {
      $(".clickableRow").on("click", function() {
          location.href="http://google.com";

      });

});

Simply this line of code will disable all input elements

$('#yourdiv *').prop('disabled', true);

For interpolated strings:

$"Int value: {someInt:D4} or {someInt:0000}. Float: {someFloat: 00.00}"

You only need to edit your virtual device's ram, making it lower! Try 20 MB, and it will work!

From this documentation

pandas provides a single function, merge, as the entry point for all standard database join operations between DataFrame objects:

merge(left, right, how='inner', on=None, left_on=None, right_on=None,
      left_index=False, right_index=False, sort=True,
      suffixes=('_x', '_y'), copy=True, indicator=False)

And :

DataFrame.join is a convenient method for combining the columns of two potentially differently-indexed DataFrames into a single result DataFrame. Here is a very basic example: The data alignment here is on the indexes (row labels). This same behavior can be achieved using merge plus additional arguments instructing it to use the indexes:

result = pd.merge(left, right, left_index=True, right_index=True,
how='outer')

The updated or deleted values are stored in DELETED. we can get it by the below method in trigger

Full example,

CREATE TRIGGER PRODUCT_UPDATE ON PRODUCTS
FOR UPDATE 
AS
BEGIN
DECLARE @PRODUCT_NAME_OLD VARCHAR(100)
DECLARE @PRODUCT_NAME_NEW VARCHAR(100)

SELECT @PRODUCT_NAME_OLD = product_name from DELETED
SELECT @PRODUCT_NAME_NEW = product_name from INSERTED

END

In addition to Fuji's response, we can make the handler reusable turning it into an attached property:

public static class HyperlinkExtensions
{
    public static bool GetIsExternal(DependencyObject obj)
    {
        return (bool)obj.GetValue(IsExternalProperty);
    }

    public static void SetIsExternal(DependencyObject obj, bool value)
    {
        obj.SetValue(IsExternalProperty, value);
    }
    public static readonly DependencyProperty IsExternalProperty =
        DependencyProperty.RegisterAttached("IsExternal", typeof(bool), typeof(HyperlinkExtensions), new UIPropertyMetadata(false, OnIsExternalChanged));

    private static void OnIsExternalChanged(object sender, DependencyPropertyChangedEventArgs args)
    {
        var hyperlink = sender as Hyperlink;

        if ((bool)args.NewValue)
            hyperlink.RequestNavigate += Hyperlink_RequestNavigate;
        else
            hyperlink.RequestNavigate -= Hyperlink_RequestNavigate;
    }

    private static void Hyperlink_RequestNavigate(object sender, System.Windows.Navigation.RequestNavigateEventArgs e)
    {
        Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));
        e.Handled = true;
    }
}

And use it like this:

<TextBlock>
    <Hyperlink NavigateUri="https://stackoverflow.com"
               custom:HyperlinkExtensions.IsExternal="true">
        Click here
    </Hyperlink>
</TextBlock>

Globals in Python are global to a module, not across all modules. (Many people are confused by this, because in, say, C, a global is the same across all implementation files unless you explicitly make it static.)

There are different ways to solve this, depending on your actual use case.

Before even going down this path, ask yourself whether this really needs to be global. Maybe you really want a class, with f as an instance method, rather than just a free function? Then you could do something like this:

import module1
thingy1 = module1.Thingy(a=3)
thingy1.f()

If you really do want a global, but it's just there to be used by module1, set it in that module.

import module1
module1.a=3
module1.f()

On the other hand, if a is shared by a whole lot of modules, put it somewhere else, and have everyone import it:

import shared_stuff
import module1
shared_stuff.a = 3
module1.f()

… and, in module1.py:

import shared_stuff
def f():
    print shared_stuff.a

Don't use a from import unless the variable is intended to be a constant. from shared_stuff import a would create a new a variable initialized to whatever shared_stuff.a referred to at the time of the import, and this new a variable would not be affected by assignments to shared_stuff.a.

Or, in the rare case that you really do need it to be truly global everywhere, like a builtin, add it to the builtin module. The exact details differ between Python 2.x and 3.x. In 3.x, it works like this:

import builtins
import module1
builtins.a = 3
module1.f()

Simply floating both elements left achieves the same result.

div {
background:yellow;
vertical-align:middle;
margin:10px;
}

a {
background-color:#FFF;
width:20px;
height:20px;
display:inline-block;
border:solid black 1px;
float:left;
}

span {
background:red;
display:inline-block;
float:left;
}

This question is kind of old, but wanted to share something which worked for me. Hope it will be useful for people who are searching for some information accessing properties in an external location.

This is what has worked for me.

1. Property file contents:

   PROVIDER_URL=t3://localhost:8003,localhost:8004
   

2. applicationContext.xml file contents: (Spring 3.2.3)

   Note: ${user.home} is a system property from OS.

   <context:property-placeholder system-properties-mode="OVERRIDE" location="file:${user.home}/myapp/latest/bin/my-env.properties"/>
   
   <bean id="appsclusterJndiTemplate" class="org.springframework.jndi.JndiTemplate">
       <property name="environment">
           <props>
               <prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
               <prop key="java.naming.provider.url">${PROVIDER_URL}</prop>
           </props>
       </property>
   </bean>
   

${PROVIDER_URL} got replaced with the value in the properties the file

HTML

<select id="mySelect">
    <option value="volvo">Volvo</option>
    <option value="saab">Saab</option>

 var mySelect = document.getElementById('mySelect'),

In addition to the answers given above, check the last line of the error message in your console. In my case, the 'site-packages' path in sys.path.append('.....') was wrong.

While the EGit plugin for Eclipse is a good option, an even better one would be to learn to use git bash -- i.e., git from the command line. It isn't terribly difficult to learn the very basics of git, and it is often very beneficial to understand some basic operations before relying on a GUI to do it for you. But to answer your question:

First things first, download git from http://git-scm.com/. Then go to http://github.com/ and create an account and repository.

On your machine, first you will need to navigate to the project folder using git bash. When you get there you do:

git init

which initiates a new git repository in that directory.

When you've done that, you need to register that new repo with a remote (where you'll upload -- push -- your files to), which in this case will be github. This assumes you have already created a github repository. You'll get the correct URL from your repo in GitHub.

git remote add origin https://github.com/[username]/[reponame].git

You need to add you existing files to your local commit:

git add .   # this adds all the files

Then you need to make an initial commit, so you do:

git commit -a -m "Initial commit" # this stages your files locally for commit. 
                                  # they haven't actually been pushed yet

Now you've created a commit in your local repo, but not in the remote one. To put it on the remote, you do the second line you posted:

git push -u origin --all

To put it simply:

> var a = 1
undefined
> a.__proto__
[Number: 0]
> Number.prototype
[Number: 0]
> Number.prototype === a.__proto__
true

This allows you to attach properties to X.prototype AFTER objects of type X has been instantiated, and they will still get access to those new properties through the __proto__ reference which the Javascript-engine uses to walk up the prototype chain.

If you aren’t using Auto Layout, have you tried setting the child view’s autoresize mask? Try this:

myChildeView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                                 UIViewAutoresizingFlexibleHeight);

Also, you may need to call

myParentView.autoresizesSubviews = YES;

to get the parent view to resize its subviews automatically when its frame changes.

If you’re still seeing the child view drawing outside of the parent view’s frame, there’s a good chance that the parent view is not clipping its contents. To fix that, call

myParentView.clipsToBounds = YES;

len(response['Items'])

will give you the count of the filtered rows

where,

fe = Key('entity').eq('tesla')
response = table.scan(FilterExpression=fe)

Using display:inline-block; it will work only for a correct sentence with spaces like

#container {_x000D_
    width: 30%;_x000D_
    background-color: grey;_x000D_
    overflow:hidden;_x000D_
    margin:10px;_x000D_
}_x000D_
#container p{_x000D_
    display:inline-block;_x000D_
    background-color: green;_x000D_
}

<h5>Correct sentence with spaces </h5>_x000D_
<div id="container">_x000D_
    <p>Sample Text 1 Sample Text 1 Sample Text 1 Sample Text 1 Sample Text 1 Sample Text 1 Sample Text 1</p>_x000D_

<div id="container">_x000D_
    <p>SampleSampleSampleSampleSampleSampleSampleSampleSampleSampleSamplesadasdsadasdasdsa</p>_x000D_

Why not using word-wrap: break-word;? it's made to allow long words to be able to break and wrap onto the next line.

#container {_x000D_
    width: 30%;_x000D_
    background-color: grey;_x000D_

Had the same problem. Turned out it was caused by iptables connection tracking on the upstream server. After removing --state NEW,ESTABLISHED,RELATED from the firewall script and flushing with conntrack -F the problem was gone.

The syntax has changed in that print is now a function. This means that the % formatting needs to be done inside the parenthesis:¹

print("%d. %s appears %d times." % (i, key, wordBank[key]))

However, since you are using Python 3.x., you should actually be using the newer str.format method:

print("{}. {} appears {} times.".format(i, key, wordBank[key]))

Though % formatting is not officially deprecated (yet), it is discouraged in favor of str.format and will most likely be removed from the language in a coming version (Python 4 maybe?).

_{¹Just a minor note: %d is the format specifier for integers, not %s.}

When the branch is no remote branch you can push your local branch direct to the remote.

git checkout master
git push origin master

or when you have a dev branch

git checkout dev
git push origin dev

or when the remote branch exists

git branch dev -t origin/dev

There are some other posibilites to push a remote branch.

From RFC 6750, Section 1.2:

Bearer Token

A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

The Bearer Token or Refresh token is created for you by the Authentication server. When a user authenticates your application (client) the authentication server then goes and generates for your a Bearer Token (refresh token) which you can then use to get an access token.

The Bearer Token is normally some kind of cryptic value created by the authentication server, it isn't random it is created based upon the user giving you access and the client your application getting access.

See also: Mozilla MDN Header Information.

There's nothing in the stdlib that will do it for you without creating tuple garbage, but it's not too hard to write your own. Unfortunately I've never bothered to figure out how to do the proper CanBuildFrom implicit raindance to make such things generic in the type of collection they're applied to, but if it's possible, I'm sure someone will enlighten us. :)

def foreachWithIndex[A](as: Traversable[A])(f: (Int,A) => Unit) {
  var i = 0
  for (a <- as) {
    f(i, a)
    i += 1
  }
}

def mapWithIndex[A,B](in: List[A])(f: (Int,A) => B): List[B] = {
  def mapWithIndex0(in: List[A], gotSoFar: List[B], i: Int): List[B] = {
    in match {
      case Nil         => gotSoFar.reverse
      case one :: more => mapWithIndex0(more, f(i, one) :: gotSoFar, i+1)
    }
  }
  mapWithIndex0(in, Nil, 0)
}

// Tests....

@Test
def testForeachWithIndex() {
  var out = List[Int]()
  ScalaUtils.foreachWithIndex(List(1,2,3,4)) { (i, num) =>
    out :+= i * num
  }
  assertEquals(List(0,2,6,12),out)
}

@Test
def testMapWithIndex() {
  val out = ScalaUtils.mapWithIndex(List(4,3,2,1)) { (i, num) =>
    i * num
  }

  assertEquals(List(0,3,4,3),out)
}

In my case I could not set 'width' and 'height' to null because I'm using TypeScript.

The way I fixed it was by setting them to '100%':

backgroundImage: {
    flex: 1,
    width: '100%',
    height: '100%',
    resizeMode: 'cover',        
}

'request.user' has the logged in user.
'request.user.username' will return username of logged in user.

If you need this procedure for variable fieldnames instead of id this might be helpful:

DROP PROCEDURE IF EXISTS update_auto_increment;
DELIMITER //
CREATE PROCEDURE update_auto_increment (_table VARCHAR(128), _fieldname VARCHAR(128))
BEGIN
    DECLARE _max_stmt VARCHAR(1024);
    DECLARE _stmt VARCHAR(1024);    
    SET @inc := 0;

    SET @MAX_SQL := CONCAT('SELECT IFNULL(MAX(',_fieldname,'), 0) + 1 INTO @inc FROM ', _table);
    PREPARE _max_stmt FROM @MAX_SQL;
    EXECUTE _max_stmt;
    DEALLOCATE PREPARE _max_stmt;

    SET @SQL := CONCAT('ALTER TABLE ', _table, ' AUTO_INCREMENT =  ', @inc);
    PREPARE _stmt FROM @SQL;
    EXECUTE _stmt;
    DEALLOCATE PREPARE _stmt;
END //
DELIMITER ;

CALL update_auto_increment('your_table_name', 'autoincrement_fieldname');

I little changed this answer. I added checking if we're using list with numbers. So now we can use it whichever way. deep_get(allTemp, [0], {}) or deep_get(getMinimalTemp, [0, minimalTemperatureKey], 26) etc

def deep_get(_dict, keys, default=None):
    def _reducer(d, key):
        if isinstance(d, dict):
            return d.get(key, default)
        if isinstance(d, list):
            return d[key] if len(d) > 0 else default
        return default
    return reduce(_reducer, keys, _dict)

A cookie is a bit of data stored by the browser and sent to the server with every request.

A session is a collection of data stored on the server and associated with a given user (usually via a cookie containing an id code)

I am not sure does it suit you but I noticed that tar does not fail on changed/deleted files in pipe mode. See what I mean.

Test script:

#!/usr/bin/env bash
set -ex
tar cpf - ./files | aws s3 cp - s3://my-bucket/files.tar
echo $?

Deleting random files manually...

Output:

+ aws s3 cp - s3://my-bucket/files.tar
+ tar cpf - ./files
tar: ./files/default_images: File removed before we read it
tar: ./files: file changed as we read it
+ echo 0

I followed the link shared by lisachenko and found another link to this blog: http://guilhembichot.blogspot.co.uk/2013/11/with-recursive-and-mysql.html

The post lays out ways of emulating the 2 uses of SQL WITH. Really good explanation on how these work to do a similar query as SQL WITH.

1) Use WITH so you don't have to perform the same sub query multiple times

CREATE VIEW D AS (SELECT YEAR, SUM(SALES) AS S FROM T1 GROUP BY YEAR);
SELECT D1.YEAR, (CASE WHEN D1.S>D2.S THEN 'INCREASE' ELSE 'DECREASE' END) AS TREND
FROM
 D AS D1,
 D AS D2
WHERE D1.YEAR = D2.YEAR-1;
DROP VIEW D;

2) Recursive queries can be done with a stored procedure that makes the call similar to a recursive with query.

CALL WITH_EMULATOR(
"EMPLOYEES_EXTENDED",
"
  SELECT ID, NAME, MANAGER_ID, 0 AS REPORTS
  FROM EMPLOYEES
  WHERE ID NOT IN (SELECT MANAGER_ID FROM EMPLOYEES WHERE MANAGER_ID IS NOT NULL)
",
"
  SELECT M.ID, M.NAME, M.MANAGER_ID, SUM(1+E.REPORTS) AS REPORTS
  FROM EMPLOYEES M JOIN EMPLOYEES_EXTENDED E ON M.ID=E.MANAGER_ID
  GROUP BY M.ID, M.NAME, M.MANAGER_ID
",
"SELECT * FROM EMPLOYEES_EXTENDED",
0,
""
);

And this is the code or the stored procedure

# Usage: the standard syntax:
#   WITH RECURSIVE recursive_table AS
#    (initial_SELECT
#     UNION ALL
#     recursive_SELECT)
#   final_SELECT;
# should be translated by you to 
# CALL WITH_EMULATOR(recursive_table, initial_SELECT, recursive_SELECT,
#                    final_SELECT, 0, "").

# ALGORITHM:
# 1) we have an initial table T0 (actual name is an argument
# "recursive_table"), we fill it with result of initial_SELECT.
# 2) We have a union table U, initially empty.
# 3) Loop:
#   add rows of T0 to U,
#   run recursive_SELECT based on T0 and put result into table T1,
#   if T1 is empty
#      then leave loop,
#      else swap T0 and T1 (renaming) and empty T1
# 4) Drop T0, T1
# 5) Rename U to T0
# 6) run final select, send relult to client

# This is for *one* recursive table.
# It would be possible to write a SP creating multiple recursive tables.

You may use MessageBox if you want but it is recommended to use alert (from JavaScript) instead.

If you want to use it you should write:

System.Windows.Forms.MessageBox.Show("Test");   

Note that you must specify the namespace.

Data URIs are now supported by all major browsers. IE supports embedding images since version 8 as well.

http://caniuse.com/#feat=datauri

Data URIs are now supported by the following web browsers:

• Gecko-based, such as Firefox, SeaMonkey, XeroBank, Camino, Fennec and K-Meleon
• Konqueror, via KDE's KIO slaves input/output system
• Opera (including devices such as the Nintendo DSi or Wii)
• WebKit-based, such as Safari (including on iOS), Android's browser, Epiphany and Midori (WebKit is a derivative of Konqueror's KHTML engine, but Mac OS X does not share the KIO architecture so the implementations are different), as well as Webkit/Chromium-based, such as Chrome
• Trident
  • Internet Explorer 8: Microsoft has limited its support to certain "non-navigable" content for security reasons, including concerns that JavaScript embedded in a data URI may not be interpretable by script filters such as those used by web-based email clients. Data URIs must be smaller than 32 KiB in Version 8[3].
  • Data URIs are supported only for the following elements and/or attributes[4]:
    • object (images only)
    • img
    • input type=image
    • link
  • CSS declarations that accept a URL, such as background-image, background, list-style-type, list-style and similar.
  • Internet Explorer 9: Internet Explorer 9 does not have 32KiB limitation and allowed in broader elements.
  • TheWorld Browser: An IE shell browser which has a built-in support for Data URI scheme

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

Test Data

DECLARE @Table1 TABLE(ID INT, Value INT)
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400)

Query

SELECT  ID
       ,STUFF((SELECT ', ' + CAST(Value AS VARCHAR(10)) [text()]
         FROM @Table1 
         WHERE ID = t.ID
         FOR XML PATH(''), TYPE)
        .value('.','NVARCHAR(MAX)'),1,2,' ') List_Output
FROM @Table1 t
GROUP BY ID

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

SQL Server 2017 and Later Versions

If you are working on SQL Server 2017 or later versions, you can use built-in SQL Server Function STRING_AGG to create the comma delimited list:

DECLARE @Table1 TABLE(ID INT, Value INT);
INSERT INTO @Table1 VALUES (1,100),(1,200),(1,300),(1,400);


SELECT ID , STRING_AGG([Value], ', ') AS List_Output
FROM @Table1
GROUP BY ID;

Result Set

+--------------------------+
¦ ID ¦     List_Output     ¦
¦----+---------------------¦
¦  1 ¦  100, 200, 300, 400 ¦
+--------------------------+

You can obfuscate it, but there's no way of protecting it completely.

example obfuscator: https://obfuscator.io

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

I think this is the more simpler approach:

1. Install mySQL-Shell package from mySQL site
2. Run mysqlsh (should be added to your path by default after install)
3. Connect to your database server like so: MySQL JS > \connect --mysql [username]@[endpoint/server]:3306
4. Switch to SQL Mode by typing "\sql" in your prompt
5. The console should print out the following to let you know you are good to go:

Switching to SQL mode... Commands end with ;

Go forth and do great things! :)

This approach will potentially discard part of the commit history, but it is easier in case the merge of the old master branch and the current status is tricky, or you simply do not mind losing part of the commit history.

To simply keep things as currently are, without merging, turning the current detached HEAD into the master branch:

1. Manually back up the repository, in case things go unexpectedly wrong.
2. Commit the last changes you would like to keep.
3. Create a temporary branch (let's name it detached-head) that will contain the files in their current status:

git checkout -b detached-head

4. (a) Delete the master branch if you do not need to keep it

git branch -D master

4. (b) OR rename if you want to keep it

git branch -M master old-master

5. Rename the temporary branch as the new master branch

git branch -M detached-head master
