1st way is to use props

<Row id = "someRandomID">

Wherein, in the Definition, you may just go

const Row = props  => {
 div id = {props.id}
}

The same could be done with class, replacing id with className in the above example.

You might as well use react-html-id, that is an npm package. This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.

Ref: react-html-id

Peace.

This can be simply done like this.

  created() {
    var scripts = [
      "https://cloudfront.net/js/jquery-3.4.1.min.js",
      "js/local.js"
    ];
    scripts.forEach(script => {
      let tag = document.createElement("script");
      tag.setAttribute("src", script);
      document.head.appendChild(tag);
    });
  }

I found it very useful, since the Exceptions are not documented, to list all exceptions to the screen for this package. Here is the code I used to do it:

import botocore.exceptions
def listexns(mod):
    #module = __import__(mod)
    exns = []
    for name in botocore.exceptions.__dict__:
        if (isinstance(botocore.exceptions.__dict__[name], Exception) or
            name.endswith('Error')):
            exns.append(name)
    for name in exns:
        print('%s.%s is an exception type' % (str(mod), name))
    return

if __name__ == '__main__':
    import sys
    if len(sys.argv) <= 1:
        print('Give me a module name on the $PYTHONPATH!')
    print('Looking for exception types in module: %s' % sys.argv[1])
    listexns(sys.argv[1])

Which results in:

Looking for exception types in module: boto3
boto3.BotoCoreError is an exception type
boto3.DataNotFoundError is an exception type
boto3.UnknownServiceError is an exception type

In case of an associative array or numbered array where you do not want to change the array keys:

$firstItem = array('foo' => 'bar');

$arr = $firstItem + $arr;

array_merge does not work as it always reindexes the array.

it also can be a great idea using concat for EL + MAP + JSON problem like in this example :

#{myMap[''.concat(myid)].content}

Given a list:

var list = new List<Child>()
{
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};

The query would look like:

var newList = list
    .GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
    .Select(y => new ConsolidatedChild()
        {
            FavoriteColor = y.Key.FavoriteColor,
            Friend = y.Key.Friend,
            School = y.Key.School,
            Children = y.ToList()
        }
    );

Test code:

foreach(var item in newList)
{
    Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
    foreach(var child in item.Children)
    {
        Console.WriteLine("\t Name: {0}", child.Name);
    }
}

Result:

School: School1 FavouriteColor: blue Friend: Bob
    Name: John
    Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
    Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
    Name: Bob

I couldn't ever find an answer that really satisfied the original question, so I put together a simple free service (PostMail) that allows you to make a standard HTTP POST request to send an email. When you sign up, it provides you with code that you can copy & paste into your website. In this case, you can simply use a form post:

HTML:

<form action="https://postmail.invotes.com/send"
    method="post" id="email_form">

    <input type="text" name="subject" placeholder="Subject" />
    <textarea name="text" placeholder="Message"></textarea>
    <!-- replace value with your access token -->
    <input type="hidden" name="access_token" value="{your access token}" />

    <input type="hidden" name="success_url"
      value=".?message=Email+Successfully+Sent%21&isError=0" />
    <input type="hidden" name="error_url"
      value=".?message=Email+could+not+be+sent.&isError=1" />

    <input id="submit_form" type="submit" value="Send" />
</form>

Again, in full disclosure, I created this service because I could not find a suitable answer.

When one of my VB.NET classes has all shared members I either convert it to a Module with a matching (or otherwise appropriate) namespace or I make the class not inheritable and not constructable:

Public NotInheritable Class MyClass1

   Private Sub New()
      'Contains only shared members.
      'Private constructor means the class cannot be instantiated.
   End Sub

End Class

I had to modify Lars' answer a bit, as an orphaned \ ended up in the regex, to only compare the actual host (not paying attention to the protocol or port) and I wanted to support localhost domain besides my production domain. Thus I changed the $allowed parameter to be an array.

function getCORSHeaderOrigin($allowed, $input)
{
    if ($allowed == '*') {
        return '*';
    }

    if (!is_array($allowed)) {
        $allowed = array($allowed);
    }

    foreach ($allowed as &$value) {
        $value = preg_quote($value, '/');

        if (($wildcardPos = strpos($value, '\*')) !== false) {
            $value = str_replace('\*', '(.*)', $value);
        }
    }

    $regexp = '/^(' . implode('|', $allowed) . ')$/';

    $inputHost = parse_url($input, PHP_URL_HOST);

    if ($inputHost === null || !preg_match($regexp, $inputHost, $matches)) {
        return 'none';
    }

    return $input;
}

Usage as follows:

if (isset($_SERVER['HTTP_ORIGIN'])) {
    header("Access-Control-Allow-Origin: " . getCORSHeaderOrigin(array("*.myproduction.com", "localhost"), $_SERVER['HTTP_ORIGIN']));
}

$newDate = preg_replace("/(\d+)\D+(\d+)\D+(\d+)/","$3-$2-$1",$originalDate);

This code works for every date format.

You can change the order of replacement variables such $3-$1-$2 due to your old date format.

If we want to apply the same functionality and features to more than one selectors then we use multiple selector options. I think we can say this feature is used like reusability. write a jquery function and just add multiple selectors in which we want the same features.

Kindly take a look in below example:

$( "div, span, .paragraph, #paraId" ).css( {"font-family": "tahoma", "background": "red"} );

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div>Div element</div>_x000D_
<p class="paragraph">Paragraph with class selector</p>_x000D_
<p id="paraId">Paragraph with id selector</p>_x000D_
<span>Span element</span>

I hope it will help you. Namaste

It is better to use scanf(" %[^\n]",str) in c++ than cin.ignore() after cin>> statement.To do that first you have to include < cstdio > header.

Because Intent has size limit . I use public static object to do pass bitmap from service to broadcast ....

public class ImageBox {
    public static Queue<Bitmap> mQ = new LinkedBlockingQueue<Bitmap>(); 
}

pass in my service

private void downloadFile(final String url){
        mExecutorService.submit(new Runnable() {
            @Override
            public void run() {
                Bitmap b = BitmapFromURL.getBitmapFromURL(url);
                synchronized (this){
                    TaskCount--;
                }
                Intent i = new Intent(ACTION_ON_GET_IMAGE);
                ImageBox.mQ.offer(b);
                sendBroadcast(i);
                if(TaskCount<=0)stopSelf();
            }
        });
    }

My BroadcastReceiver

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
        public void onReceive(Context context, Intent intent) {
            LOG.d(TAG, "BroadcastReceiver get broadcast");

            String action = intent.getAction();
            if (DownLoadImageService.ACTION_ON_GET_IMAGE.equals(action)) {
                Bitmap b = ImageBox.mQ.poll();
                if(b==null)return;
                if(mListener!=null)mListener.OnGetImage(b);
            }
        }
    };

Big Theta notation:

Nothing to mess up buddy!!

If we have a positive valued functions f(n) and g(n) takes a positive valued argument n then ?(g(n)) defined as {f(n):there exist constants c1,c2 and n1 for all n>=n1}

where c1 g(n)<=f(n)<=c2 g(n)

Let's take an example:

let f(n)=

g(n)=

c1=5 and c2=8 and n1=1

Among all the notations ,? notation gives the best intuition about the rate of growth of function because it gives us a tight bound unlike big-oh and big -omega which gives the upper and lower bounds respectively.

? tells us that g(n) is as close as f(n),rate of growth of g(n) is as close to the rate of growth of f(n) as possible.

Is the standard procedure not working?

The most problems appear when you want to add new host to dynamic inventory (via add_host module) in playbook. I don't want to disable fingerprint host checking permanently so solutions like disabling it in a global config file are not ok for me. Exporting var like ANSIBLE_HOST_KEY_CHECKING before running playbook is another thing to do before running that need to be remembered.

It's better to add local config file in the same dir where playbook is. Create file named ansible.cfg and paste following text:

[defaults]
host_key_checking = False

No need to remember to add something in env vars or add to ansible-playbook options. It's easy to put this file to ansible git repo.

This will work for any resolution,

button{
    position:absolute;
    bottom: 5%;
    right:20%;
}

In Angular 2 you can subscribe (Rx event) to a Router instance. So you can do things like

class MyClass {
  constructor(private router: Router) {
    router.subscribe((val) => /*whatever*/)
  }
}

Edit (since rc.1)

class MyClass {
  constructor(private router: Router) {
    router.changes.subscribe((val) => /*whatever*/)
  }
}

Edit 2 (since 2.0.0)

see also : Router.events doc

class MyClass {
  constructor(private router: Router) {
    router.events.subscribe((val) => {
        // see also 
        console.log(val instanceof NavigationEnd) 
    });
  }
}

Take a look at the Cursor.Position Property. It should get you started.

private void MoveCursor()
{
   // Set the Current cursor, move the cursor's Position,
   // and set its clipping rectangle to the form. 

   this.Cursor = new Cursor(Cursor.Current.Handle);
   Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
   Cursor.Clip = new Rectangle(this.Location, this.Size);
}

$_SERVER['SERVER_NAME'] is based on your web servers configuration. $_SERVER['HTTP_HOST'] is based on the request from the client.

You push your local repository to the remote repository using the git push command after first establishing a relationship between the two with the git remote add [alias] [url] command. If you visit your Github repository, it will show you the URL to use for pushing. You'll first enter something like:

git remote add origin [email protected]:username/reponame.git

Unless you started by running git clone against the remote repository, in which case this step has been done for you already.

And after that, you'll type:

git push origin master

After your first push, you can simply type:

git push

when you want to update the remote repository in the future.

WebView browser = (WebView) findViewById(R.id.webview);
browser.getSettings().setLoadWithOverviewMode(true);
browser.getSettings().setUseWideViewPort(true);
browser.getSettings().setMinimumFontSize(40);

This works great for me since the text size has been set to really small by .setLoadWithOverViewMode and .setUseWideViewPort.

Why are you including the getClassLoader step? If you say "this.getClass().getResource()" you should be getting resources relative to the calling class. I've never used ClassLoader.getResource(), though from a quick look at the Java Docs it sounds like that will get you the first resource of that name found in any current classpath.

Another Javascript Solution

for(var i=0,keys = Object.keys(obj),len=keys.length;i<len;i++){ 
  if(typeof obj[keys[i]] === 'undefined'){
    delete obj[keys[i]];
  }
}

No additional hasOwnProperty check is required as Object.keys does not look up the prototype chain and returns only the properties of obj.

I use the below mentioned process to convert equations to markdown. This works very well for me. Its very simple!!

Let's say, I want to represent matrix multiplication equation

Step 1:

Get the script for your formulae from here - https://csrgxtu.github.io/2015/03/20/Writing-Mathematic-Fomulars-in-Markdown/

My example: I wanted to represent Z(i,j)=X(i,k) * Y(k, j); k=1 to n into a summation formulae.



Referencing the website, the script needed was => Z_i_j=\sum_{k=1}^{10} X_i_k * Y_k_j

Step 2:

Use URL encoder - https://www.urlencoder.org/ to convert the script to a valid url

My example:

Step 3:

Use this website to generate the image by copy-pasting the output from Step 2 in the "eq" request parameter - http://www.sciweavers.org/tex2img.php?eq=<b><i>paste-output-here</i></b>&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=

- My example:
http://www.sciweavers.org/tex2img.php?eq=Z_i_j=\sum_{k=1}^{10}%20X_i_k%20*%20Y_k_j&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=

Step 4:

Reference image using markdown syntax - ![alt text](enter url here)

- Copy this in your markdown and you are good to go:

![Z(i,j)=X(i,k) * Y(k, j); k=1 to n](http://www.sciweavers.org/tex2img.php?eq=Z_i_j%3D%5Csum_%7Bi%3D1%7D%5E%7B10%7D%20X_i_k%20%2A%20Y_k_j&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=)

Image below is the output of markdown. Hurray!!

You get that error because you don't have the public key of the person who signed the message.

gpg should have given you a message containing the ID of the key that was used to sign it. Obtain the public key from the person who encrypted the file and import it into your keyring (gpg2 --import key.asc); you should be able to verify the signature after that.

If the sender submitted its public key to a keyserver (for instance, https://pgp.mit.edu/), then you may be able to import the key directly from the keyserver:

gpg2 --keyserver https://pgp.mit.edu/ --search-keys <sender_name_or_address>

Java always uses at least 32 bit values for calculations. This is due to the 32-bit architecture which was common 1995 when java was introduced. The register size in the CPU was 32 bit and the arithmetic logic unit accepted 2 numbers of the length of a cpu register. So the cpus were optimized for such values.

This is the reason why all datatypes which support arithmetic opperations and have less than 32-bits are converted to int (32 bit) as soon as you use them for calculations.

So to sum up it mainly was due to performance issues and is kept nowadays for compatibility.

I was able to import the module within the function (only) that would require the objects from this module:

def my_func():
    import Foo
    foo_instance = Foo()

Always use either String.valueOf(number) or Integer.toString(number).

Using "" + number is an overhead and does the following:

StringBuilder sb = new StringBuilder();
sb.append("");
sb.append(number);
return sb.toString();

And how about this:

public static void watchYoutubeVideo(Context context, String id){
    Intent appIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:" + id));
    Intent webIntent = new Intent(Intent.ACTION_VIEW,
                Uri.parse("http://www.youtube.com/watch?v=" + id));
    try {
        context.startActivity(appIntent);
    } catch (ActivityNotFoundException ex) {
        context.startActivity(webIntent);
    }
} 

Note: Beware when you are using this method, YouTube may suspend your channel due to spam, this happened two times with me

Yup, as everyone's saying, line-height is the thing. Any font you are using, a mid-height character (such as a or ¦, not going through the upper or lower) should go with the same height-length at line-height: 0.6 to 0.65.

Sometime in the future .NET4.6

//for Double
double inputValues = double.Parse(Console.ReadLine());

//for Int
int inputValues = int.Parse(Console.ReadLine());

I believe

rgba( 0, 0, 0, 0.8 )

is equivalent in shade with #333.

Setting background size does not help, the following solution worked for me:

.class {
    background-image: url(blablabla.jpg);
    /* Add this */
    height: auto;
}

It basically crops the image and makes it fit in, background-size: contain/cover still didn't make it fit.

Might be a bit odd or bad practice but this is one way of going about it.

(arg1, arg2, arg3) = (1, 2, 3)

if (arg1 == 1)*(arg2 == 2)*(arg3 == 3):
    print('Example.')

Anything multiplied by 0 == 0. If any of these conditions fail then it evaluates to false.

You can use templates.

template <typename T> const char* typeof(T&) { return "unknown"; }    // default
template<> const char* typeof(int&) { return "int"; }
template<> const char* typeof(float&) { return "float"; }

In the example above, when the type is not matched it will print "unknown".

str_split can do the trick. Note that strings in PHP can be accessed just like a chars array, in most cases, you won't need to split your string into a "new" array.

Exactly as arrays in all C-like languages. The indexes start from 0. So, apple is 0, banana is 1, orange is 2 etc.

The value of the length property must be greater than or equal to name atribute length, else throwing an error.

Works

@Column(name = "typ e", length = 4, unique = true)
private String type;

Not works, type.length: 4 != length property: 3

@Column(name = "type", length = 3, unique = true)
private String type;

Another type of solution would be to autogenerate the nginx conf files via Jinja2 templates from ansible. The advantage of this is easy deployment to a cloud environment, and easy to replicate on multiple dev machines

In my case it is required to calculate the complete month from the start date to the day prior to this day in the next month or from start to end of month.

Ex: from 1/1/2018 to 31/1/2018 is a complete month
Ex2: from 5/1/2018 to 4/2/2018 is a complete month

so based on this here is my solution:

public static DateTime GetMonthEnd(DateTime StartDate, int MonthsCount = 1)
{
    return StartDate.AddMonths(MonthsCount).AddDays(-1);
}
public static Tuple<int, int> CalcPeriod(DateTime StartDate, DateTime EndDate)
{
    int MonthsCount = 0;
    Tuple<int, int> Period;
    while (true)
    {
        if (GetMonthEnd(StartDate) > EndDate)
            break;
        else
        {
            MonthsCount += 1;
            StartDate = StartDate.AddMonths(1);
        }
    }
    int RemainingDays = (EndDate - StartDate).Days + 1;
    Period = new Tuple<int, int>(MonthsCount, RemainingDays);
    return Period;
}

Usage:

Tuple<int, int> Period = CalcPeriod(FromDate, ToDate);

Note: in my case it was required to calculate the remaining days after the complete months so if it's not your case you could ignore the days result or even you could change the method return from tuple to integer.

One way to solve this problem, specialization of member functions is to put the specialization into another class, then inherit from that class. You may have to change the order of inheritence to get access to all of the other underlying data but this technique does work.

template< class T, bool condition> struct FooImpl;
template<class T> struct FooImpl<T, true> {
T foo() { return 10; }
};

template<class T> struct FoolImpl<T,false> {
T foo() { return 5; }
};

template< class T >
class Y : public FooImpl<T, boost::is_integer<T> > // whatever your test is goes here.
{
public:
    typedef FooImpl<T, boost::is_integer<T> > inherited;

    // you will need to use "inherited::" if you want to name any of the 
    // members of those inherited classes.
};

The disadvantage of this technique is that if you need to test a lot of different things for different member functions you'll have to make a class for each one, and chain it in the inheritence tree. This is true for accessing common data members.

Ex:

template<class T, bool condition> class Goo;
// repeat pattern above.

template<class T, bool condition>
class Foo<T, true> : public Goo<T, boost::test<T> > {
public:
    typedef Goo<T, boost::test<T> > inherited:
    // etc. etc.
};

That worked for me:

input:

[complex(a,b) for a,b in zip([1,2,3],[1,2,3])]

output:

[(1+4j), (2+5j), (3+6j)]

A simple example would be

    DECLARE @number INTEGER
    DECLARE @length INTEGER
    DECLARE @char   NVARCHAR(10)
    SET @number = 1
    SET @length = 5
    SET @char = '0'

    SELECT FORMAT(@number, replicate(@char, @length))

If your integer is timestamp in milliseconds use:

SELECT strftime("%Y-%d-%m", col_name, 'unixepoch') AS col_name

It will format milliseconds to yyyy-mm-dd string.

except:

accepts all exceptions, whereas

except Exception as e:

only accepts exceptions that you're meant to catch.

Here's an example of one that you're not meant to catch:

>>> try:
...     input()
... except:
...     pass
... 
>>> try:
...     input()
... except Exception as e:
...     pass
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
KeyboardInterrupt

The first one silenced the KeyboardInterrupt!

Here's a quick list:

issubclass(BaseException, BaseException)
#>>> True
issubclass(BaseException, Exception)
#>>> False


issubclass(KeyboardInterrupt, BaseException)
#>>> True
issubclass(KeyboardInterrupt, Exception)
#>>> False


issubclass(SystemExit, BaseException)
#>>> True
issubclass(SystemExit, Exception)
#>>> False

If you want to catch any of those, it's best to do

except BaseException:

to point out that you know what you're doing.

All exceptions stem from BaseException, and those you're meant to catch day-to-day (those that'll be thrown for the programmer) inherit too from Exception.

A non-jQuery solution is much like a jQuery solution:

document.querySelector('#myinput').getAttribute('type') === 'checkbox'

I know what you're going to say, the guys before me wrote the same thing. But I got confused using the steps above this post, and I wanted to write a dumb down version for people who have the latest version of the IDE.

This is a known issue in Chrome and resolved in latest versions. Please refer https://bugs.chromium.org/p/chromium/issues/detail?id=942440 for more details.

After spending hours on this issue found solution here

import { FormsModule, ReactiveFormsModule } from '@angular/forms';
    
@NgModule({
    imports: [
         FormsModule,
         ReactiveFormsModule      
    ]
})

It sounds like you currently have 3 copies of the entire file in memory: the byte array, the string, and the array of the lines.

Instead of reading the bytes into a byte array and then converting to characters using new String() it would be better to use an InputStreamReader, which will convert to characters incrementally, rather than all up-front.

Also, instead of using String.split("\n") to get the individual lines, you should read one line at a time. You can use the readLine() method in BufferedReader.

Try something like this:

BufferedReader reader = new BufferedReader(new InputStreamReader(fileInputStream, "UTF-8"));
try {
  while (true) {
    String line = reader.readLine();
    if (line == null) break;
    String[] fields = line.split(",");
    // process fields here
  }
} finally {
  reader.close();
}

Some interesting excerpts from the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.
...
When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of /etc/bash.bashrc and ~/.bashrc.

So have a look at /etc/profile or /etc/bash.bashrc, these files are the right places for global settings. Put something like this in them to set up an environement variable:

export MY_VAR=xxx

If input stream is not closed properly then this exception may happen. make sure : If inputstream used is not used "Before" in some way then where you are intended to read. i.e if read 2nd time from same input stream in single operation then 2nd call will get this exception. Also make sure to close input stream in finally block or something like that.

A nested dict is a dictionary within a dictionary. A very simple thing.

>>> d = {}
>>> d['dict1'] = {}
>>> d['dict1']['innerkey'] = 'value'
>>> d
{'dict1': {'innerkey': 'value'}}

You can also use a defaultdict from the collections package to facilitate creating nested dictionaries.

>>> import collections
>>> d = collections.defaultdict(dict)
>>> d['dict1']['innerkey'] = 'value'
>>> d  # currently a defaultdict type
defaultdict(<type 'dict'>, {'dict1': {'innerkey': 'value'}})
>>> dict(d)  # but is exactly like a normal dictionary.
{'dict1': {'innerkey': 'value'}}

You can populate that however you want.

I would recommend in your code something like the following:

d = {}  # can use defaultdict(dict) instead

for row in file_map:
    # derive row key from something 
    # when using defaultdict, we can skip the next step creating a dictionary on row_key
    d[row_key] = {} 
    for idx, col in enumerate(row):
        d[row_key][idx] = col

According to your comment:

may be above code is confusing the question. My problem in nutshell: I have 2 files a.csv b.csv, a.csv has 4 columns i j k l, b.csv also has these columns. i is kind of key columns for these csvs'. j k l column is empty in a.csv but populated in b.csv. I want to map values of j k l columns using 'i` as key column from b.csv to a.csv file

My suggestion would be something like this (without using defaultdict):

a_file = "path/to/a.csv"
b_file = "path/to/b.csv"

# read from file a.csv
with open(a_file) as f:
    # skip headers
    f.next()
    # get first colum as keys
    keys = (line.split(',')[0] for line in f) 

# create empty dictionary:
d = {}

# read from file b.csv
with open(b_file) as f:
    # gather headers except first key header
    headers = f.next().split(',')[1:]
    # iterate lines
    for line in f:
        # gather the colums
        cols = line.strip().split(',')
        # check to make sure this key should be mapped.
        if cols[0] not in keys:
            continue
        # add key to dict
        d[cols[0]] = dict(
            # inner keys are the header names, values are columns
            (headers[idx], v) for idx, v in enumerate(cols[1:]))

Please note though, that for parsing csv files there is a csv module.

You don't always want to discard a race condition. If you have a flag which can be read and written by multiple threads, and this flag is set to 'done' by one thread so that other thread stop processing when flag is set to 'done', you don't want that "race condition" to be eliminated. In fact, this one can be referred to as a benign race condition.

However, using a tool for detection of race condition, it will be spotted as a harmful race condition.

More details on race condition here, http://msdn.microsoft.com/en-us/magazine/cc546569.aspx.

For those not using arrow functions but something simpler ... I encountered this when adding parentheses after my signOut function ...

After a lot of searching I could not find an exact example of a single SQL Server trigger that handles all (3) three conditions of the trigger actions INSERT, UPDATE, and DELETE. I finally found a line of text that talked about the fact that when a DELETE or UPDATE occurs, the common DELETED table will contain a record for these two actions. Based upon that information, I then created a small Action routine which determines why the trigger has been activated. This type of interface is sometimes needed when there is both a common configuration and a specific action to occur on an INSERT vs. UPDATE trigger. In these cases, to create a separate trigger for the UPDATE and the INSERT would become maintenance problem. (i.e. were both triggers updated properly for the necessary common data algorithm fix?)

To that end, I would like to give the following multi-trigger event code snippet for handling INSERT, UPDATE, DELETE in one trigger for an Microsoft SQL Server.

CREATE TRIGGER [dbo].[INSUPDDEL_MyDataTable]
ON [dbo].[MyDataTable] FOR INSERT, UPDATE, DELETE
AS 

-- SET NOCOUNT ON added to prevent extra result sets from

DECLARE @Action as char(1)
DECLARE @Count as int
SET @Action = 'I' -- Set Action to 'I'nsert by default.
SELECT @Count = COUNT(*) FROM DELETED
if @Count > 0
    BEGIN
        SET @Action = 'D' -- Set Action to 'D'eleted.
        SELECT @Count = COUNT(*) FROM INSERTED
        IF @Count > 0
            SET @Action = 'U' -- Set Action to 'U'pdated.
    END

if @Action = 'D'

    END

            BEGIN
                INSERT INTO [MyChildTable]
                    (([PACKLIST_ID]
                    ,[LINE_NO]
                    ,[STATUS]
                VALUES
                    (@PACKLIST_ID
                    ,@LINE_NO
                    ,'New Record'
                    )
            END
        else
            -- This is an Update Record Action
            --
            BEGIN
                UPDATE [MyChildTable]
                    SET [PACKLIST_ID] = @PACKLIST_ID
                          ,[LINE_NO] = @LINE_NO
                          ,[STATUS]='Update Record'

You need the following permissions in your manifest file:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

You'll find a nice tutorial on the subject on this site.

Drop the parentheses and commas:

 myBackupFunction ".." "..." "xx"

And the function should look like this:

function myBackupFunction() {
    # Here $1 is the first parameter, $2 the second, etc.
}

Sadly there is no overload in PHP as it is done in C#. But i have a little trick. I declare arguments with default null values and check them in a function. That way my function can do different things depending on arguments. Below is simple example:

public function query($queryString, $class = null) //second arg. is optional
{
    $query = $this->dbLink->prepare($queryString);
    $query->execute();

    //if there is second argument method does different thing
    if (!is_null($class)) { 
        $query->setFetchMode(PDO::FETCH_CLASS, $class);
    }

    return $query->fetchAll();
}

//This loads rows in to array of class
$Result = $this->query($queryString, "SomeClass");
//This loads rows as standard arrays
$Result = $this->query($queryString);

One more option in simple way

Map<String,Choice> map = new HashMap<>();
choices.forEach(e->map.put(e.getName(),e));

To get started, you should download the source code from Github, by following the instructions here (you'll need Bazel and a recent version of GCC).

The C++ API (and the backend of the system) is in tensorflow/core. Right now, only the C++ Session interface, and the C API are being supported. You can use either of these to execute TensorFlow graphs that have been built using the Python API and serialized to a GraphDef protocol buffer. There is also an experimental feature for building graphs in C++, but this is currently not quite as full-featured as the Python API (e.g. no support for auto-differentiation at present). You can see an example program that builds a small graph in C++ here.

The second part of the C++ API is the API for adding a new OpKernel, which is the class containing implementations of numerical kernels for CPU and GPU. There are numerous examples of how to build these in tensorflow/core/kernels, as well as a tutorial for adding a new op in C++.

Works for every browser.

<button type="button" onClick="Refresh()">Close</button>

I think you could just use class "col-md-12" it has required left and right paddings and 100% width. Looks like this is a good replacement for container-fluid from 2nd bootstrap.

The solution using flexbox without justify-content: space-between.

<div class="title">
  <span>Cumulative performance</span>
  <span>20/02/2011</span>
</div>

.title {
  display: flex;
}

span:first-of-type {
  flex: 1;
}

When we use flex:1 on the first <span>, it takes up the entire remaining space and moves the second <span> to the right. The Fiddle with this solution: https://jsfiddle.net/2k1vryn7/

Here https://jsfiddle.net/7wvx2uLp/3/ you can see the difference between two flexbox approaches: flexbox with justify-content: space-between and flexbox with flex:1 on the first <span>.

There seems to be a really easy solution when dealing with data type issues.

Basically, at the end of Excel connection string, add ;IMEX=1;"

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\YOURSERVER\shared\Client Projects\FOLDER\Data\FILE.xls;Extended Properties="EXCEL 8.0;HDR=YES;IMEX=1";

This will resolve data type issues such as columns where values are mixed with text and numbers.

To get to connection property, right click on Excel connection manager below control flow and hit properties. It'll be to the right under solution explorer. Hope that helps.

I wrote a short convenience function for posting JSON.

$.postJSON = function(url, data, success, args) {
  args = $.extend({
    url: url,
    type: 'POST',
    data: JSON.stringify(data),
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    async: true,
    success: success
  }, args);
  return $.ajax(args);
};

$.postJSON('test/url', data, function(result) {
  console.log('result', result);
});

An updated answer here as of 2017, should anyone need it, is that onhashchange is well supported in all major browsers. See caniuse for details. To use it with jQuery no plugin is needed:

$( window ).on( 'hashchange', function( e ) {
    console.log( 'hash changed' );
} );

Occasionally I come across legacy systems where hashbang URL's are still used and this is helpful. If you're building something new and using hash links I highly suggest you consider using the HTML5 pushState API instead.

Followings gives dimensions as well as channels:

import numpy as np
from PIL import Image

with Image.open(filepath) as img:
    shape = np.array(img).shape

Breaking out of Array#forEach is not possible. (You can inspect the source code that implements it in Firefox on the linked page, to confirm this.)

Instead you should use a normal for loop:

function recurs(comment) {
    for (var i = 0; i < comment.comments.length; ++i) {
        var subComment = comment.comments[i];
        recurs(subComment);
        if (...) {
            break;
        }
    }
}

(or, if you want to be a little more clever about it and comment.comments[i] is always an object:)

function recurs(comment) {
    for (var i = 0, subComment; subComment = comment.comments[i]; ++i) {
        recurs(subComment);
        if (...) {
            break;
        }
    }
}

I couldn't get the first method to work, and I know this is an old topic, but this is what I ended up doing for a solution:

=IF(ISNA(MATCH(A1,B:B,0)),"Not Matched", A1)

Basically, MATCH A1 to Column B exactly (the 0 stands for match exactly to a value in Column B). ISNA tests for #N/A response which match will return if the no match is found. Finally, if ISNA is true, write "Not Matched" to the selected cell, otherwise write the contents of the matched cell.

fatal error: unexpectedly found nil while unwrapping an Optional value

1. Check the IBOutlet collection , because this error will have chance to unconnected uielement object usage.

:) hopes it will help for some struggled people .

Edit: Warning! This answer worked on my XAMPP OsX environment, but when I deployed it to AWS EC2 it did NOT prevent the upload attempt.

I was tempted to delete this answer as it is WRONG But instead I will explain what tripped me up

My file upload field is named 'upload' so I was getting "The upload failed to upload.". This message comes from this line in validation.php:

in resources/lang/en/validaton.php:

'uploaded' => 'The :attribute failed to upload.',

And this is the message displayed when the file is larger than the limit set by PHP.

I want to over-ride this message, which you normally can do by passing a third parameter $messages array to Validator::make() method.

However I can't do that as I am calling the POST from a React Component, which renders the form containing the csrf field and the upload field.

So instead, as a super-dodgy-hack, I chose to get into my view that displays the messages and replace that specific message with my friendly 'file too large' message.

Here is what works if the file to smaller than the PHP file size limit:

In case anyone else is using Laravel FormRequest class, here is what worked for me on Laravel 5.7:

This is how I set a custom error message and maximum file size:

I have an input field <input type="file" name="upload">. Note the CSRF token is required also in the form (google laravel csrf_field for what this means).

<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class Upload extends FormRequest
{
  ...
  ...
  public function rules() {
    return [
      'upload' => 'required|file|max:8192',
    ];
  }
  public function messages()
  {
    return [            
      'upload.required' => "You must use the 'Choose file' button to select which file you wish to upload",
      'upload.max' => "Maximum file size to upload is 8MB (8192 KB). If you are uploading a photo, try to reduce its resolution to make it under 8MB"
    ];
  }
}

You could add a method to String to make it more semantic:

String.metaClass.getNotBlank = { !delegate.allWhitespace }

which let's you do:

groovy:000> foo = ''
===> 
groovy:000> foo.notBlank
===> false
groovy:000> foo = 'foo'
===> foo
groovy:000> foo.notBlank
===> true

Try this:

private void NewNumber()
  {
     Random a = new Random(Guid.newGuid().GetHashCode());
     MyNumber = a.Next(0, 10);
  }

Some Explnations:

Guid : base on here : Represents a globally unique identifier (GUID)

Guid.newGuid() produces a unique identifier like "936DA01F-9ABD-4d9d-80C7-02AF85C822A8"

and it will be unique in all over the universe base on here

Hash code here produce a unique integer from our unique identifier

so Guid.newGuid().GetHashCode() gives us a unique number and the random class will produce real random numbers throw this

Sample: https://rextester.com/ODOXS63244

generated ten random numbers with this approach with result of:

-1541116401
7
-1936409663

we got two 1s next to each other, but the hash codes do not same.

I just made this for my app :

public static Date getDatePart(Date dateTime) {
    TimeZone tz = TimeZone.getDefault();
    long rawOffset=tz.getRawOffset();
    long dst=(tz.inDaylightTime(dateTime)?tz.getDSTSavings():0);
    long dt=dateTime.getTime()+rawOffset+dst; // add offseet and dst to dateTime
    long modDt=dt % (60*60*24*1000) ;

    return new Date( dt
                    - modDt // substract the rest of the division by a day in milliseconds
                    - rawOffset // substract the time offset (Paris = GMT +1h for example)
                    - dst // If dayLight, substract hours (Paris = +1h in dayLight)
    );
}

Android API level 1, no external library. It respects daylight and default timeZone. No String manipulation so I think this way is more CPU efficient than yours but I haven't made any tests.

Try this:

sudo chmod +x program_name
./program_name 

class _YourClassState extends State<YourClass> {
  TextEditingController _controller = TextEditingController();

  @override
  void initState() {
    super.initState();
    _controller.text = 'Your message';
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      color: Colors.white,
      child: TextFormField(
        controller: _controller,
        decoration: InputDecoration(labelText: 'Send message...'),
      ),
    );
  }
}

As a quick and very scoped solution:

Task.Result

Both Task.Result and Task.Wait won't allow to improving scalability when used with I/O, as they will cause the calling thread to stay blocked waiting for the I/O to end.

When you call .Result on an incomplete Task, the thread executing the method has to sit and wait for the task to complete, which blocks the thread from doing any other useful work in the meantime. This negates the benefit of the asynchronous nature of the task.

TLDR

~ is what you want most of the time, it references past commits to the current branch

^ references parents (git-merge creates a 2nd parent or more)

A~ is always the same as A^
A~~ is always the same as A^^, and so on
A~2 is not the same as A^2 however,
because ~2 is shorthand for ~~
while ^2 is not shorthand for anything, it means the 2nd parent

Beside Gambol's answer that will do the job in nearly all cases, all answers given so far missed that the grouped formatting (8-4-4-4-12) is not mandatory to encode GUIDs in text. It's used extremely often but obviously also a plain chain of 32 hexadecimal digits can be valid.^[1] regex_enh:

/^[0-9a-f]{8}-?[0-9a-f]{4}-?[1-5][0-9a-f]{3}-?[89ab][0-9a-f]{3}-?[0-9a-f]{12}$/i

^[1] The question is about checking variables, so we should include the user-unfriendly form as well.

My problem was in my XML lyout I have an android:animateLayoutChanges set to true and I've called notifyDataSetChanged() on the RecyclerView's adapter in the Java code.

So, I've just removed android:animateLayoutChanges from my layout and that resloved my problem.

The problem is that your ui property uses a forward declaration of class Ui::MainWindowClass, hence the "incomplete type" error.

Including the header file in which this class is declared will fix the problem.

EDIT

Based on your comment, the following code:

namespace Ui
{
    class MainWindowClass;
}

does NOT declare a class. It's a forward declaration, meaning that the class will exist at some point, at link time.
Basically, it just tells the compiler that the type will exist, and that it shouldn't warn about it.

But the class has to be defined somewhere.

Note this can only work if you have a pointer to such a type.
You can't have a statically allocated instance of an incomplete type.

So either you actually want an incomplete type, and then you should declare your ui member as a pointer:

namespace Ui
{
    // Forward declaration - Class will have to exist at link time
    class MainWindowClass;
}

class MainWindow : public QMainWindow
{
    private:

        // Member needs to be a pointer, as it's an incomplete type
        Ui::MainWindowClass * ui;
};

Or you want a statically allocated instance of Ui::MainWindowClass, and then it needs to be declared. You can do it in another header file (usually, there's one header file per class).
But simply changing the code to:

namespace Ui
{
    // Real class declaration - May/Should be in a specific header file
    class MainWindowClass
    {};
}


class MainWindow : public QMainWindow
{
    private:

        // Member can be statically allocated, as the type is complete
        Ui::MainWindowClass ui;
};

will also work.

Note the difference between the two declarations. First uses a forward declaration, while the second one actually declares the class (here with no properties nor methods).

The design of C# suggests that inline initialization is preferred, or it wouldn't be in the language. Any time you can avoid a cross-reference between different places in the code, you're generally better off.

There is also the matter of consistency with static field initialization, which needs to be inline for best performance. The Framework Design Guidelines for Constructor Design say this:

? CONSIDER initializing static fields inline rather than explicitly using static constructors, because the runtime is able to optimize the performance of types that don’t have an explicitly defined static constructor.

"Consider" in this context means to do so unless there's a good reason not to. In the case of static initializer fields, a good reason would be if initialization is too complex to be coded inline.

You can use nonzero function. it returns the nonzero indices of the given input.

Easy Way

>>> (e > 15).nonzero()

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

to see the indices more cleaner, use transpose method:

>>> numpy.transpose((e>15).nonzero())

[[1 6]
 [1 7]
 [1 8]
 [1 9]
 [2 0]
 ...

Not Bad Way

>>> numpy.nonzero(e > 15)

(array([1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2]), array([6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9]))

or the clean way:

>>> numpy.transpose(numpy.nonzero(e > 15))

[[1 6]
 [1 7]
 [1 8]
 [1 9]
 [2 0]
 ...

Make sure your code is in DOM Ready as pointed by rocket-hazmat

.click()

$('#RootNode').click(function(){
  //do something
});

document.getElementById("RootNode").onclick = function(){//do something}

Use event Delegation/

$(document).on("click", "#RootNode", function(){
   //do something
});

Wrap Code in Dom Ready

$(document).ready(function(){
    $('#RootNode').click(function(){
     //do something
    });
});

Use read_table(filepath). The default separator is tab

Select all text in the document and press Ctrl + E + D.

You don't need to configure anything. Just make sure that the requests map to your PHP file and use requests with path info. For example, if you have in the root a file named handler.php with this content:

<?php

var_dump($_SERVER['REQUEST_METHOD']);
var_dump($_SERVER['REQUEST_URI']);
var_dump($_SERVER['PATH_INFO']);

if (($stream = fopen('php://input', "r")) !== FALSE)
    var_dump(stream_get_contents($stream));

The following HTTP request would work:

Established connection with 127.0.0.1 on port 81
PUT /handler.php/bla/foo HTTP/1.1
Host: localhost:81
Content-length: 5
 
boo
HTTP/1.1 200 OK
Date: Sat, 29 May 2010 16:00:20 GMT

Content-Type: text/html
 
string(3) "PUT"
string(20) "/handler.php/bla/foo"
string(8) "/bla/foo"
string(5) "boo
"
Connection closed remotely.

You can hide the "php" extension with MultiViews or you can make URLs completely logical with mod_rewrite.

jQuery.offset needs to be combined with scrollTop and scrollLeft as shown in this diagram:

Demo:

function getViewportOffset($e) {_x000D_
  var $window = $(window),_x000D_
    scrollLeft = $window.scrollLeft(),_x000D_
    scrollTop = $window.scrollTop(),_x000D_
    offset = $e.offset(),_x000D_
    rect1 = { x1: scrollLeft, y1: scrollTop, x2: scrollLeft + $window.width(), y2: scrollTop + $window.height() },_x000D_
    rect2 = { x1: offset.left, y1: offset.top, x2: offset.left + $e.width(), y2: offset.top + $e.height() };_x000D_
  return {_x000D_
    left: offset.left - scrollLeft,_x000D_
    top: offset.top - scrollTop,_x000D_
    insideViewport: rect1.x1 < rect2.x2 && rect1.x2 > rect2.x1 && rect1.y1 < rect2.y2 && rect1.y2 > rect2.y1_x000D_
  };_x000D_
}_x000D_
$(window).on("load scroll resize", function() {_x000D_
  var viewportOffset = getViewportOffset($("#element"));_x000D_
  $("#log").text("left: " + viewportOffset.left + ", top: " + viewportOffset.top + ", insideViewport: " + viewportOffset.insideViewport);_x000D_
});

body { margin: 0; padding: 0; width: 1600px; height: 2048px; background-color: #CCCCCC; }_x000D_

You would need to always consider the state of all checkboxes!

You could increase or decrease a number on checking or unchecking, but imagine the site loads with three of them checked.

So you always need to check all of them:

<script type="text/javascript">
<!--
function showMe (it, box) {
  // consider all checkboxes with same name
  var checked = amountChecked(box.name);

  var vis = (checked >= 3) ? "block" : "none";
  document.getElementById(it).style.display = vis;
}

function amountChecked(name) {
  var all = document.getElementsByName(name);

  // count checked
  var result = 0;
  all.forEach(function(el) {
    if (el.checked) result++;
  });

  return result;
}
//-->
</script>

Angular 2 or 4:

There's no more ng-repeat, it's *ngFor now in recent Angular versions!

<table style="padding: 20px; width: 60%;">
    <tr>
      <th  align="left">id</th>
      <th  align="left">status</th>
      <th  align="left">name</th>
    </tr>
    <tr *ngFor="let item of myJSONArray">
      <td>{{item.id}}</td>
      <td>{{item.status}}</td>
      <td>{{item.name}}</td>
    </tr>
</table>

Used this simple JSON:

[{"id":1,"status":"active","name":"A"},
{"id":2,"status":"live","name":"B"},
{"id":3,"status":"active","name":"C"},
{"id":6,"status":"deleted","name":"D"},
{"id":4,"status":"live","name":"E"},
{"id":5,"status":"active","name":"F"}]

This is a classic difficulty in LaTeX.

The problem is how to do layout with floats (figures and tables, an similar objects) and footnotes. In particular, it is hard to pick a place for a float with certainty that making room for the associated footnotes won't cause trouble. So the standard tabular and figure environments don't even try.

What can you do:

1. Fake it. Just put a hardcoded vertical skip at the bottom of the caption and then write the footnote yourself (use \footnotesize for the size). You also have to manage the symbols or number yourself with \footnotemark. Simple, but not very attractive, and the footnote does not appear at the bottom of the page.
2. Use the tabularx, longtable, threeparttable[x] (kudos to Joseph) or ctable which support this behavior.
3. Manage it by hand. Use [h!] (or [H] with the float package) to control where the float will appear, and \footnotetext on the same page to put the footnote where you want it. Again, use \footnotemark to install the symbol. Fragile and requires hand-tooling every instance.
4. The footnotes package provides the savenote environment, which can be used to do this.
5. Minipage it (code stolen outright, and read the disclaimer about long caption texts in that case):

    \begin{figure}
      \begin{minipage}{\textwidth}
        ...
        \caption[Caption for LOF]%
          {Real caption\footnote{blah}}
      \end{minipage}
    \end{figure}

Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.

You can check this by running in Windows PowerShell:

> Get-Service ssh-agent

And then check the output of status is not running.

Status   Name               DisplayName
------   ----               -----------
Stopped  ssh-agent          OpenSSH Authentication Agent

Then check that the service has been disabled by running

> Get-Service ssh-agent | Select StartType

StartType
---------
Disabled

I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:

 > Get-Service -Name ssh-agent | Set-Service -StartupType Manual

Alternatively, you can set it through the GUI if you prefer.

Try This Simple and Effective

 .home > span + .red{
      border:1px solid red;
    }

You should have to add only minViewMode: "months" in your datepicker function.

Since .NET 4.5 the Validators use data-attributes and bounded Javascript to do the validation work, so .NET expects you to add a script reference for jQuery.

There are two possible ways to solve the error:

Disable UnobtrusiveValidationMode:

Add this to web.config:

<configuration>
    <appSettings>
        <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
    </appSettings>
</configuration>

It will work as it worked in previous .NET versions and will just add the necessary Javascript to your page to make the validators work, instead of looking for the code in your jQuery file. This is the common solution actually.

Another solution is to register the script:

In Global.asax Application_Start add mapping to your jQuery file path:

void Application_Start(object sender, EventArgs e) 
{
    // Code that runs on application startup
    ScriptManager.ScriptResourceMapping.AddDefinition("jquery", 
    new ScriptResourceDefinition
    {
        Path = "~/scripts/jquery-1.7.2.min.js",
        DebugPath = "~/scripts/jquery-1.7.2.js",
        CdnPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.1.min.js",
        CdnDebugPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.1.js"
    });
}

Some details from MSDN:

ValidationSettings:UnobtrusiveValidationMode Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.

If this key value is set to "None" [default], the ASP.NET application will use the pre-4.5 behavior (JavaScript inline in the pages) for client-side validation logic.

If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script reference for client-side validation logic.

How about this:

df1 = pandas.DataFrame(data = {'col1' : [1, 2, 3, 4, 5], 
                               'col2' : [10, 11, 12, 13, 14]}) 
df2 = pandas.DataFrame(data = {'col1' : [1, 2, 3], 
                               'col2' : [10, 11, 12]})
records_df2 = set([tuple(row) for row in df2.values])
in_df2_mask = np.array([tuple(row) in records_df2 for row in df1.values])
result = df1[~in_df2_mask]

on OSX assure you have launched the Docker application before issuing

docker ps

or docker build ... etc ... yes it seems strange and somewhat misleading that issuing

docker --version

gives version even though the docker daemon is not running ... ditto for those other version cmds ... I just encountered exactly the same symptoms ... this behavior on OSX is different from on linux

Toward this same directions, I'm posting a client and server snipets that send Excel Files using WebApi, c# 4:

public static void SetFile(String serviceUrl, byte[] fileArray, String fileName)
{
    try
    {
        using (var client = new HttpClient())
        {
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                using (var content = new MultipartFormDataContent())
                {
                    var fileContent = new ByteArrayContent(fileArray);//(System.IO.File.ReadAllBytes(fileName));
                    fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
                    {
                        FileName = fileName
                    };
                    content.Add(fileContent);
                    var result = client.PostAsync(serviceUrl, content).Result;
                }
        }
    }
    catch (Exception e)
    {
        //Log the exception
    }
}

And the server webapi controller:

public Task<IEnumerable<string>> Post()
{
    if (Request.Content.IsMimeMultipartContent())
    {
        string fullPath = HttpContext.Current.Server.MapPath("~/uploads");
        MyMultipartFormDataStreamProvider streamProvider = new MyMultipartFormDataStreamProvider(fullPath);
        var task = Request.Content.ReadAsMultipartAsync(streamProvider).ContinueWith(t =>
        {
            if (t.IsFaulted || t.IsCanceled)
                    throw new HttpResponseException(HttpStatusCode.InternalServerError);

            var fileInfo = streamProvider.FileData.Select(i =>
            {
                var info = new FileInfo(i.LocalFileName);
                return "File uploaded as " + info.FullName + " (" + info.Length + ")";
            });
            return fileInfo;

        });
        return task;
    }
    else
    {
        throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.NotAcceptable, "Invalid Request!"));
    }
}

And the Custom MyMultipartFormDataStreamProvider, needed to customize the Filename:

PS: I took this code from another post http://www.codeguru.com/csharp/.net/uploading-files-asynchronously-using-asp.net-web-api.htm

public class MyMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
{
    public MyMultipartFormDataStreamProvider(string path)
        : base(path)
    {

    }

    public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
    {
        string fileName;
        if (!string.IsNullOrWhiteSpace(headers.ContentDisposition.FileName))
        {
            fileName = headers.ContentDisposition.FileName;
        }
        else
        {
            fileName = Guid.NewGuid().ToString() + ".data";
        }
        return fileName.Replace("\"", string.Empty);
    }
}

Eureka ! Finally I found a solution on this.

This is caused by Windows update that stops any 32-bit processes from consuming more than 1200 MB on a 64-bit machine. The only way you can repair this is by using the System Restore option on Win 7.

Start >> All Programs >> Accessories >> System Tools >> System Restore.

And then restore to a date on which your Java worked fine. This worked for me. What is surprising here is Windows still pushes system updates under the name of "Critical Updates" even when you disable all windows updates. ^&%)#* Windows :-)

in standart Vi editor in this situation you should

1. press Esc
2. type ":wq" (without quotes)
3. Press Enter

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

Solution

To see the option for USB debugging mode in Nexus 4 or Android 4.2 or higher OS, do the following:

• Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
• Now scroll to the bottom and tap “About phone” or “About tablet”.
• At the “About” screen, scroll to the bottom and tap on “Build number” seven times.
  • Make sure you tap seven times. If you see a “Not need, you are already a developer!” message pop up, then you know you have done it correctly.

Done! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.

CONCLUSION

That was easy. The best part is you only have to do the tap-build-number-seven-times once. After you do it once, USB debugging has been unlocked and you can enable or disable at your leisure. Please restart after done these steps.

For me issue got resolved after following steps :

1. Installing python 32 bit version on windows.
2. Add newly installed python and it's script folder(where pip resides in environment variable)

Issue comes when any application you want to run needs python 32 bit variants and you have 64 bit variant

Note : Once you install python 32 bit variant,dont forget to install all required packages using pip of this new python 32 bit variant

try this:

<div style='overflow:auto; width:400px;height:400px;'>here is some text</div>

Try Like This: For SQL SERVER 2008+

SELECT c.name AS ColName, t.name AS TableName
FROM sys.columns c
    JOIN sys.tables t ON c.object_id = t.object_id
WHERE c.name LIKE '%MyColumnaName%'

Or

SELECT COLUMN_NAME, TABLE_NAME 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE COLUMN_NAME LIKE '%MyName%'

Or Something Like This:

SELECT name  
FROM sys.tables 
WHERE OBJECT_ID IN ( SELECT id 
              FROM syscolumns 
              WHERE name like '%COlName%' )

git-subtree is nice, but it is probably not the one you want.

For example, if projectA is the directory created in B, after git subtree,

git log projectA

lists only one commit: the merge. The commits from the merged project are for different paths, so they don't show up.

Greg Hewgill's answer comes closest, although it doesn't actually say how to rewrite the paths.

The solution is surprisingly simple.

(1) In A,

PREFIX=projectA #adjust this

Note: This rewrites history; you may want to first make a backup of A.

Note Bene: You have to modify the substitute script inside the sed command in the case that you use non-ascii characters (or white characters) in file names or path. In that case the file location inside a record produced by "ls-files -s" begins with quotation mark.

(2) Then in B, run

git pull path/to/A

Voila! You have a projectA directory in B. If you run git log projectA, you will see all commits from A.

In my case, I wanted two subdirectories, projectA and projectB. In that case, I did step (1) to B as well.

Generally, there is a mistake in the HTTP verb used eg:

Calling PUT route with POST request

I'll add a map and filter version because why not.

sum(map(lambda x:x>5, j))
sum(1 for _ in filter(lambda x:x>5, j))

 public class State
        {
            public int SID { get; set; }
            public string SName { get; set; }
            public string SCode { get; set; }
            public string SAbbrevation { get; set; }
        }

        public class Country
        {
            public int CID { get; set; }
            public string CName { get; set; }
            public string CAbbrevation { get; set; }
        }


 List<State> states = new List<State>()
            {
               new  State{  SID=1,SName="Telangana",SCode="+91",SAbbrevation="TG"},
               new  State{  SID=2,SName="Texas",SCode="512",SAbbrevation="TS"},
            };

            List<Country> coutries = new List<Country>()
            {
               new Country{CID=1,CName="India",CAbbrevation="IND"},
               new Country{CID=2,CName="US of America",CAbbrevation="USA"},
            };

            var res = coutries.Join(states, a => a.CID, b => b.SID, (a, b) => new {a.CName,b.SName}).ToList();

Does this work without alternation?

^((part)1(, \22)?)?(part2)?$

or why not this?

^((part)1(, (\22))?)?(\4)?$

The first works for all conditions the second for all but part2(using GNU sed 4.1.5)

There are a couple of variables to set the max number of connections. Most likely, you're running out of file numbers first. Check ulimit -n. After that, there are settings in /proc, but those default to the tens of thousands.

More importantly, it sounds like you're doing something wrong. A single TCP connection ought to be able to use all of the bandwidth between two parties; if it isn't:

• Check if your TCP window setting is large enough. Linux defaults are good for everything except really fast inet link (hundreds of mbps) or fast satellite links. What is your bandwidth*delay product?
• Check for packet loss using ping with large packets (ping -s 1472 ...)
• Check for rate limiting. On Linux, this is configured with tc
• Confirm that the bandwidth you think exists actually exists using e.g., iperf
• Confirm that your protocol is sane. Remember latency.
• If this is a gigabit+ LAN, can you use jumbo packets? Are you?

Possibly I have misunderstood. Maybe you're doing something like Bittorrent, where you need lots of connections. If so, you need to figure out how many connections you're actually using (try netstat or lsof). If that number is substantial, you might:

• Have a lot of bandwidth, e.g., 100mbps+. In this case, you may actually need to up the ulimit -n. Still, ~1000 connections (default on my system) is quite a few.
• Have network problems which are slowing down your connections (e.g., packet loss)
• Have something else slowing you down, e.g., IO bandwidth, especially if you're seeking. Have you checked iostat -x?

Also, if you are using a consumer-grade NAT router (Linksys, Netgear, DLink, etc.), beware that you may exceed its abilities with thousands of connections.

I hope this provides some help. You're really asking a networking question.

This is working as documented. Any paths specified in PYTHONPATH are documented as normally coming after the working directory but before the standard interpreter-supplied paths. sys.path.append() appends to the existing path. See here and here. If you want a particular directory to come first, simply insert it at the head of sys.path:

import sys
sys.path.insert(0,'/path/to/mod_directory')

That said, there are usually better ways to manage imports than either using PYTHONPATH or manipulating sys.path directly. See, for example, the answers to this question.

targetList = sourceList.stream().flatmap(List::stream).collect(Collectors.toList());

What do you mean with "without iterating"?

You can use map.entrySet().iterator().next() and you wouldn't iterate through map (in the meaning of "touching each object"). You can't get hold of an Entry<K, V> without using an iterator though. The Javadoc of Map.Entry says:

The Map.entrySet method returns a collection-view of the map, whose elements are of this class. The only way to obtain a reference to a map entry is from the iterator of this collection-view. These Map.Entry objects are valid only for the duration of the iteration.

Can you explain in more detail, what you are trying to accomplish? If you want to handle objects first, that match a specific criterion (like "have a particular key") and fall back to the remaining objects otherwise, then look at a PriorityQueue. It will order your objects based on natural order or a custom-defined Comparator that you provide.

Try:
//category[@name='Sport' and ./author/text()='James Small']

It worked i used userdell --force USERNAME Some times eventhough -f and --force is same -f is not working sometimes After i removed the account i exit back to that removed username which i removed from root then what happened is this

For example, in your component before you declare your @Component

const en = require('../assets/en.json');

Addition after very useful comment of mhand at the end

Original answer

Although most solutions might work, I think they are not very efficiently. Suppose if you only want the first few items of the first few chunks. Then you wouldn't want to iterate over all (zillion) items in your sequence.

The following will at utmost enumerate twice: once for the Take and once for the Skip. It won't enumerate over any more elements than you will use:

public static IEnumerable<IEnumerable<TSource>> ChunkBy<TSource>
    (this IEnumerable<TSource> source, int chunkSize)
{
    while (source.Any())                     // while there are elements left
    {   // still something to chunk:
        yield return source.Take(chunkSize); // return a chunk of chunkSize
        source = source.Skip(chunkSize);     // skip the returned chunk
    }
}

How many times will this Enumerate the sequence?

Suppose you divide your source into chunks of chunkSize. You enumerate only the first N chunks. From every enumerated chunk you'll only enumerate the first M elements.

While(source.Any())
{
     ...
}

the Any will get the Enumerator, do 1 MoveNext() and returns the returned value after Disposing the Enumerator. This will be done N times

yield return source.Take(chunkSize);

According to the reference source this will do something like:

public static IEnumerable<TSource> Take<TSource>(this IEnumerable<TSource> source, int count)
{
    return TakeIterator<TSource>(source, count);
}

static IEnumerable<TSource> TakeIterator<TSource>(IEnumerable<TSource> source, int count)
{
    foreach (TSource element in source)
    {
        yield return element;
        if (--count == 0) break;
    }
}

This doesn't do a lot until you start enumerating over the fetched Chunk. If you fetch several Chunks, but decide not to enumerate over the first Chunk, the foreach is not executed, as your debugger will show you.

If you decide to take the first M elements of the first chunk then the yield return is executed exactly M times. This means:

• get the enumerator
• call MoveNext() and Current M times.
• Dispose the enumerator

After the first chunk has been yield returned, we skip this first Chunk:

source = source.Skip(chunkSize);

Once again: we'll take a look at reference source to find the skipiterator

static IEnumerable<TSource> SkipIterator<TSource>(IEnumerable<TSource> source, int count)
{
    using (IEnumerator<TSource> e = source.GetEnumerator()) 
    {
        while (count > 0 && e.MoveNext()) count--;
        if (count <= 0) 
        {
            while (e.MoveNext()) yield return e.Current;
        }
    }
}

As you see, the SkipIterator calls MoveNext() once for every element in the Chunk. It doesn't call Current.

So per Chunk we see that the following is done:

• Any(): GetEnumerator; 1 MoveNext(); Dispose Enumerator;

• Take():

  • nothing if the content of the chunk is not enumerated.

  • If the content is enumerated: GetEnumerator(), one MoveNext and one Current per enumerated item, Dispose enumerator;

  • Skip(): for every chunk that is enumerated (NOT the contents of the chunk): GetEnumerator(), MoveNext() chunkSize times, no Current! Dispose enumerator

If you look at what happens with the enumerator, you'll see that there are a lot of calls to MoveNext(), and only calls to Current for the TSource items you actually decide to access.

If you take N Chunks of size chunkSize, then calls to MoveNext()

• N times for Any()
• not yet any time for Take, as long as you don't enumerate the Chunks
• N times chunkSize for Skip()

If you decide to enumerate only the first M elements of every fetched chunk, then you need to call MoveNext M times per enumerated Chunk.

The total

MoveNext calls: N + N*M + N*chunkSize
Current calls: N*M; (only the items you really access)

So if you decide to enumerate all elements of all chunks:

MoveNext: numberOfChunks + all elements + all elements = about twice the sequence
Current: every item is accessed exactly once

Whether MoveNext is a lot of work or not, depends on the type of source sequence. For lists and arrays it is a simple index increment, with maybe an out of range check.

But if your IEnumerable is the result of a database query, make sure that the data is really materialized on your computer, otherwise the data will be fetched several times. DbContext and Dapper will properly transfer the data to local process before it can be accessed. If you enumerate the same sequence several times it is not fetched several times. Dapper returns an object that is a List, DbContext remembers that the data is already fetched.

It depends on your Repository whether it is wise to call AsEnumerable() or ToLists() before you start to divide the items in Chunks

You're looking for the OpenFileDialog class.

For example:

Sub SomeButton_Click(sender As Object, e As EventArgs) Handles SomeButton.Click
    Using dialog As New OpenFileDialog
        If dialog.ShowDialog() <> DialogResult.OK Then Return
        File.Copy(dialog.FileName, newPath)
    End Using
End Sub

In a ASP.NET Core project you can use the QueryHelpers class, available in the Microsoft.AspNetCore.WebUtilities namespace for ASP.NET Core, or the .NET Standard 2.0 NuGet package for other consumers:

// using Microsoft.AspNetCore.WebUtilities;
var query = new Dictionary<string, string>
{
    ["foo"] = "bar",
    ["foo2"] = "bar2",
    // ...
};

var response = await client.GetAsync(QueryHelpers.AddQueryString("/api/", query));

Its seems that server is not running properly so ensure that with terminal by

telnet ip port

example

telnet localhost 8069

It will return connected to localhost so it indicates that there is no problem with the connection Else it will return Connection refused it indicates that there is problem with the connection

Git has the concept of "remotes", which are simply URLs to other copies of your repository. When you clone another repository, Git automatically creates a remote named "origin" and points to it.

You can see more information about the remote by typing git remote show origin.

well here is common usage of getter setter in actual use case,

public class OrderItem 
{
public int Id {get;set;}
public int quantity {get;set;}
public int Price {get;set;}
public int TotalAmount {get {return this.quantity *this.Price;}set;}
}

Clustering uses shared storage of some kind (a drive cage or a SAN, for example), and puts two database front-ends on it. The front end servers share an IP address and cluster network name that clients use to connect, and they decide between themselves who is currently in charge of serving client requests.

If you're asking about a particular database server, add that to your question and we can add details on their implementation, but at its core, that's what clustering is.

The most important concern about private methods and attributes is to tell developers not to call it outside the class and this is encapsulation. one may misunderstand security from encapsulation. when one deliberately uses syntax like that(bellow) you mentioned, you do not want encapsulation.

You can plot the means without resorting to external calculations and additional tables using stat_summary(...). In fact, stat_summary(...) was designed for exactly what you are doing.

library(ggplot2)
library(reshape2)            # for melt(...)
gg <- melt(df,id="gender")   # df is your original table
ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  scale_color_discrete("Gender")
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey80",position=position_dodge(1), width=.2)

To add "error bars" you cna also use stat_summary(...) (here, I'm using the min and max value rather than sd because you have so little data).

ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey40",position=position_dodge(1), width=.2) +
  scale_fill_discrete("Gender")

1. you can work with this website for generate favin.ico
2. I recommend use .ico format because the png don't work with method 1 and ico could have more detail!
3. both method work with all browser but when it's automatically work what you want type a code for it? so i think method 1 is better.

I already found it:

SELECT grantee, privilege_type 
FROM information_schema.role_table_grants 
WHERE table_name='mytable'

Here is a basic example that explains the callback() function in JavaScript:

var x = 0;_x000D_
_x000D_
function testCallBack(param1, param2, callback) {_x000D_
  alert('param1= ' + param1 + ', param2= ' + param2 + ' X=' + x);_x000D_
  if (callback && typeof(callback) === "function") {_x000D_
    x += 1;_x000D_
    alert("Calla Back x= " + x);_x000D_
    x += 1;_x000D_
    callback();_x000D_
  }_x000D_
}_x000D_
_x000D_
testCallBack('ham', 'cheese', function() {_x000D_
  alert("Function X= " + x);_x000D_
});

It's simple use:

long millis = new Date().getTime();

if you want it in particular format then you need Formatter like below

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String millisInString  = dateFormat.format(new Date());

this is a select command

   FROM
    user
WHERE
    application_key = 'dsfdsfdjsfdsf'
        AND email NOT LIKE '%applozic.com'
        AND email NOT LIKE '%gmail.com'
        AND email NOT LIKE '%kommunicate.io';

this update command

 UPDATE user
    SET email = null
    WHERE application_key='dsfdsfdjsfdsf' and  email not like '%applozic.com' 
    and email not like '%gmail.com'  and email not like '%kommunicate.io';

I was using ADO.NET and was using SQL Command as:

 string query =
"SELECT * " +
"FROM table_name" +
"Where id=@id";

the thing was i missed a whitespace at the end of "FROM table_name"+ So basically it said

string query = "SELECT * FROM table_nameWHERE id=@id";

and this was causing the error.

Hope it helps

I'm not sure what changed, but I am unable to checkout a specific commit without the option --detach. The full command that worked for me was: git checkout --detach [commit hash]

To get back from the detached state I had to checkout my local branch: git checkout master

awk '{sum+=$3}; END {printf "%f",sum/NR}' ${file}_${f}_v1.xls >> to-plot-p.xls

print will insert a newline by default. You dont want that to happen, hence use printf instead.

If none of the above solutions are working, try manually adding "http://" to the beginning of the url.

Chrome can distinguish "[ip-address]:5000" from a search query. But sometimes that works for a while, and then stops connecting, seemingly without me changing anything. My hypothesis is that the browser might sometimes automatically prepend https:// (which it shouldn't, but this fixed it in my case).

you are going to want to separate your arguments into separate parameter

$msbuild = "C:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe"
$arguments = "/v:q /nologo"
start-process $msbuild $arguments 

You don't, as serialize is meant to be used as an query string, and in that context, unchecked means it's not in the querystring at all.

If you really want to get the values of unchecked checkboxes, use: (untested off course)

var arr_unchecked_values = $('input[type=checkbox]:not(:checked)').map(function(){return this.value}).get();

To convert from hex to decimal, there are many ways to do it in the shell or with an external program:

With bash:

$ echo $((16#FF))
255

with bc:

$ echo "ibase=16; FF" | bc
255

with perl:

$ perl -le 'print hex("FF");'
255

with printf :

$ printf "%d\n" 0xFF
255

with python:

$ python -c 'print(int("FF", 16))'
255

with ruby:

$ ruby -e 'p "FF".to_i(16)'
255

with node.js:

$ nodejs <<< "console.log(parseInt('FF', 16))"
255

with rhino:

$ rhino<<EOF
print(parseInt('FF', 16))
EOF
...
255

with groovy:

$ groovy -e 'println Integer.parseInt("FF",16)'
255

You can easily iterate over your view controllers if you are using a navigation controller. And then you can check for the particular instance as:
Swift 5

 if let viewControllers = navigationController?.viewControllers {
            for viewController in viewControllers {
                if viewController.isKind(of: LoginViewController.self) {
                    
                }
            }
        }

Also you can position the other window before withdrawing it so that you position your message

from tkinter import *
import tkinter.messagebox

window = Tk()
window.wm_withdraw()

# message at x:200,y:200
window.geometry("1x1+200+200")  # remember its.geometry("WidthxHeight(+or-)X(+or-)Y")
tkinter.messagebox.showerror(title="error", message="Error Message", parent=window)

# center screen message
window.geometry(f"1x1+{round(window.winfo_screenwidth() / 2)}+{round(window.winfo_screenheight() / 2)}")
tkinter.messagebox.showinfo(title="Greetings", message="Hello World!")

Please Note: This is Lewis Cowles' answer just Python 3ified, since tkinter has changed since python 2. If you want your code to be backwords compadible do something like this:

try:
    import tkinter
    import tkinter.messagebox
except ModuleNotFoundError:
    import Tkinter as tkinter
    import tkMessageBox as tkinter.messagebox

I realized that several answers have been provided but no real fix yet.

The reason, as mentioned above, is a "End of line" missing at the end of the CSV file.

While the real Fix should come from Microsoft, the walk around is to open the CSV file with a Text-editor and add a line at the end of the file (aka press return key). I use ATOM software as a text/code editor but virtually all basic text editor would do.

In the meanwhile, please report the bug to Microsoft.

Question: It seems to me that it is a office 2016 problem. Does anyone have the issue on a PC?

There are two different notations to access object properties

• Dot notation: myObj.prop1
• Bracket notation: myObj["prop1"]

Dot notation is fast and easy but you must use the actual property name explicitly. No substitution, variables, etc.

Bracket notation is open ended. It uses a string but you can produce the string using any legal js code. You may specify the string as literal (though in this case dot notation would read easier) or use a variable or calculate in some way.

So, these all set the myObj property named prop1 to the value Hello:

// quick easy-on-the-eye dot notation
myObj.prop1 = "Hello";

// brackets+literal
myObj["prop1"] = "Hello";

// using a variable
var x = "prop1"; 
myObj[x] = "Hello";                     

// calculate the accessor string in some weird way
var numList = [0,1,2];
myObj[ "prop" + numList[1] ] = "Hello";     

Pitfalls:

myObj.[xxxx] = "Hello";      // wrong: mixed notations, syntax fail
myObj[prop1] = "Hello";      // wrong: this expects a variable called prop1

tl;dnr: If you want to compute or reference the key you must use bracket notation. If you are using the key explicitly, then use dot notation for simple clear code.

Note: there are some other good and correct answers but I personally found them a bit brief coming from a low familiarity with JS on-the-fly quirkiness. This might be useful to some people.

span.style.fontSize = "25px";

use this

If you need to mutate the dictionary while enumerating:

for (NSString* key in xyz.allKeys) {
    [xyz setValue:[NSNumber numberWithBool:YES] forKey:key];
}

I think table-cell needs to have a parent display:table element.

It looks like you're trying to scale the background image? There's a great article in the reference bellow where you can use css3 to achieve this.

And if I miss-read the question then I humbly accept the votes down. (Still good to know though)

Please consider the following code:

#some_div_or_body { 
   background: url(images/bg.jpg) no-repeat center center fixed; 
   -webkit-background-size: cover;
   -moz-background-size: cover;
   -o-background-size: cover;
   background-size: cover;
}

This will work on all major browsers, of course it doesn't come easy on IE. There are some workarounds however such as using Microsoft's filters:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='.myBackground.jpg', sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='myBackground.jpg', sizingMethod='scale')";

There are some alternatives that can be used with a little bit peace of mind by using jQuery:

HTML

<img src="images/bg.jpg" id="bg" alt="">

CSS

#bg { position: fixed; top: 0; left: 0; }
.bgwidth { width: 100%; }
.bgheight { height: 100%; }

jQuery:

 $(window).load(function() {    

var theWindow        = $(window),
    $bg              = $("#bg"),
    aspectRatio      = $bg.width() / $bg.height();

function resizeBg() {

    if ( (theWindow.width() / theWindow.height()) < aspectRatio ) {
        $bg
            .removeClass()
            .addClass('bgheight');
    } else {
        $bg
            .removeClass()
            .addClass('bgwidth');
    }

}

theWindow.resize(resizeBg).trigger("resize");

});

I hope this helps!

        var input = @"ProjectName\Iteration\Release1\Iteration1";
        var pattern = @"\\Iteration";

        var rgx = new Regex(pattern);
        var result = rgx.Replace(input, "", 1);

        Assert.IsTrue(result.Equals(@"ProjectName\Release1\Iteration1"));
    }

rgx.Replace(input, "", 1); says to look in input for anything matching the pattern, with "", 1 time.

If we just use normal HTML image tag like this it is working. I use this in website made with Jekyll.

<img class="img-fluid" src="./img/face.jpg" alt="img-verification">

If we add bootstrap classes as per this example it works fine.

A year later, stumbled across this question for a inline LI problem, but have found a great solution that may apply here.

http://robertnyman.com/2010/02/24/css-display-inline-block-why-it-rocks-and-why-it-sucks/

vertical-align:bottom on all my LI elements fixed my "extra margin" problem in all browsers.

For Unix

grep "ARCHITECTURE" $ORACLE_HOME/inventory/ContentsXML/oraclehomeproperties.xml

And the output is:

<PROPERTY NAME="ARCHITECTURE" VAL="64"/> 

For Windows

findstr "ARCHITECTURE" %ORACLE_HOME%\inventory\ContentsXML\oraclehomeproperties.xml

And the output can be:

<PROPERTY NAME="ARCHITECTURE" VAL="64"/>

Writing JSON to a File

import json

data = {}
data['people'] = []
data['people'].append({
    'name': 'Scott',
    'website': 'stackabuse.com',
    'from': 'Nebraska'
})
data['people'].append({
    'name': 'Larry',
    'website': 'google.com',
    'from': 'Michigan'
})
data['people'].append({
    'name': 'Tim',
    'website': 'apple.com',
    'from': 'Alabama'
})

with open('data.txt', 'w') as outfile:
    json.dump(data, outfile)

Reading JSON from a File

import json

with open('data.txt') as json_file:
    data = json.load(json_file)
    for p in data['people']:
        print('Name: ' + p['name'])
        print('Website: ' + p['website'])
        print('From: ' + p['from'])
        print('')

Regex with replaceAll.

public class Main
{
    public static void main(final String[] argv) 
    {
        String str;

        str = "hello\r\njava\r\nbook";
        str = str.replaceAll("(\\r|\\n)", "");
        System.out.println(str);
    }
}

If you only want to remove \r\n when they are pairs (the above code removes either \r or \n) do this instead:

str = str.replaceAll("\\r\\n", "");

To clear from the current position to the end of the current line, do this:

    public static void ClearToEndOfCurrentLine()
    {
        int currentLeft = Console.CursorLeft;
        int currentTop = Console.CursorTop;
        Console.Write(new String(' ', Console.WindowWidth - currentLeft));
        Console.SetCursorPosition(currentLeft, currentTop);
    }

ArrayList has a indexOf() method. Check the API for more, but here's how it works:

private ArrayList<String> _categories; // Initialize all this stuff

private int getCategoryPos(String category) {
  return _categories.indexOf(category);
}

indexOf() will return exactly what your method returns, fast.

use npm install -g angular-cli instead of
npm install -g@nagular/cli to install Angular

You can reach each separate container using .parent() API.

Like,

var highestBox = 0;
        $('.container .column').each(function(){  
                if($(this).parent().height() > highestBox){  
                highestBox = $(this).height();  
        }
    }); 

You can do it like this -

let arr1 = [_x000D_
    { id: "abdc4051", date: "2017-01-24" },_x000D_
    { id: "abdc4052", date: "2017-01-22" }_x000D_
];_x000D_
_x000D_
let arr2 = [_x000D_
    { id: "abdc4051", name: "ab" },_x000D_
    { id: "abdc4052", name: "abc" }_x000D_
];_x000D_
_x000D_
let arr3 = arr1.map((item, i) => Object.assign({}, item, arr2[i]));_x000D_
_x000D_
console.log(arr3);

Use below code if arr1 and arr2 are in a different order:

let arr1 = [_x000D_
  { id: "abdc4051", date: "2017-01-24" }, _x000D_
  { id: "abdc4052", date: "2017-01-22" }_x000D_
];_x000D_
_x000D_
let arr2 = [_x000D_
  { id: "abdc4051", name: "ab" },_x000D_
  { id: "abdc4052", name: "abc" }_x000D_
];_x000D_
_x000D_
let merged = [];_x000D_
_x000D_
for(let i=0; i<arr1.length; i++) {_x000D_
  merged.push({_x000D_
   ...arr1[i], _x000D_
   ...(arr2.find((itmInner) => itmInner.id === arr1[i].id))}_x000D_
  );_x000D_
}_x000D_
_x000D_
console.log(merged);

Use this if arr1 and arr2 are in a same order

let arr1 = [_x000D_
  { id: "abdc4051", date: "2017-01-24" }, _x000D_
  { id: "abdc4052", date: "2017-01-22" }_x000D_
];_x000D_
_x000D_
let arr2 = [_x000D_
  { id: "abdc4051", name: "ab" },_x000D_
  { id: "abdc4052", name: "abc" }_x000D_
];_x000D_
_x000D_
let merged = [];_x000D_
_x000D_
for(let i=0; i<arr1.length; i++) {_x000D_
  merged.push({_x000D_
   ...arr1[i], _x000D_
   ...arr2[i]_x000D_
  });_x000D_
}_x000D_
_x000D_
console.log(merged);

In Swift 5, you can utilize dot notation for a bit quicker syntax:

myButton.titleLabel?.font = .systemFont(ofSize: 14, weight: .medium)

Otherwise, you'll use:

myButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)

For whatever reason, @import didn't work for me, but it's not really necessary is it?

Here's what I did instead, within the html:

  <link rel="stylesheet" media="print" href="myap-print.css">
  <link rel="stylesheet" media="print" href="myap-screen.css">
  <link rel="stylesheet" media="screen" href="myap-screen.css">

Notice that media="print" has 2 stylesheets: myap-print.css and myap-screen.css. It's the same effect as including myap-screen.css within myap-print.css.

I have employed a slightly different technique in my aspnet MVC 4 site:

_ViewStart.cshtml:

@using System.Web.Caching
@using System.Web.Hosting
@{
    Layout = "~/Views/Shared/_Layout.cshtml";
    PageData.Add("scriptFormat", string.Format("<script src=\"{{0}}?_={0}\"></script>", GetDeployTicks()));
}

@functions
{

    private static string GetDeployTicks()
    {
        const string cacheKey = "DeployTicks";
        var returnValue = HttpRuntime.Cache[cacheKey] as string;
        if (null == returnValue)
        {
            var absolute = HostingEnvironment.MapPath("~/Web.config");
            returnValue = File.GetLastWriteTime(absolute).Ticks.ToString();
            HttpRuntime.Cache.Insert(cacheKey, returnValue, new CacheDependency(absolute));
        }
        return returnValue;
    }
}

Then in the actual views:

 @Scripts.RenderFormat(PageData["scriptFormat"], "~/Scripts/Search/javascriptFile.min.js")

Command line arguments are stored as strings in the String array String[] args that is passed tomain()`.

java [program name] [arg1,arg2 ,..]

Command line arguments are the inputs that accept from the command prompt while running the program. The arguments passed can be anything. Which is stored in the args[] array.

//Display all command line information
         class ArgDemo{
            public static void main(String args[]){
            System.out.println("there are "+args.length+"command-line arguments.");
            for(int i=0;i<args.length;i++)
            System.out.println("args["+i+"]:"+args[i]);
    }
    }

Example:

java Argdemo one two

The output will be:

there are 2 command line arguments:
they are:
arg[0]:one
arg[1]:two

You can also create a shortcut on desktop that can run a specific command or even a batch file by just typing the command in "Type the Location of Item" bar in create shortcut wizard

1. Right click on Desktop.
2. Enter the command in "Type the Location of Item" bar.
3. Double click the shortcut to run the command.

Found detailed Instructions here

This may be a bit off-topic but I want to share it here because I simply wanted to remove Alerts from state after a given timeout i.e. auto hiding alerts/notifications.

I ended up using setTimeout() within the <Alert /> component, so that it can then call and dispatch a REMOVE action on given id.

export function Alert(props: Props) {
  useEffect(() => {
    const timeoutID = setTimeout(() => {
      dispatchAction({
        type: REMOVE,
        payload: {
          id: id,
        },
      });
    }, timeout ?? 2000);
    return () => clearTimeout(timeoutID);
  }, []);
  return <AlertComponent {...props} />;
}

Source article: Passing a list as an argument to a vararg method

Use the toArray(T[] arr) method.

.getMap(locations.toArray(new WorldLocation[locations.size()]))

(toArray(new WorldLocation[0]) also works, but you would allocate a zero-length array for no reason.)

Here's a complete example:

public static void method(String... strs) {
    for (String s : strs)
        System.out.println(s);
}

...
    List<String> strs = new ArrayList<String>();
    strs.add("hello");
    strs.add("world");
    
    method(strs.toArray(new String[strs.size()]));
    //     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...

That is invalid syntax. You are mixing relational expressions with scalar operators (OR). Specifically you cannot combine expr IN (select ...) OR (select ...). You probably want expr IN (select ...) OR expr IN (select ...). Using union would also work: expr IN (select... UNION select...)

When you do this,

while((inputLine = buff_read.readLine())!= null){
        System.out.println(inputLine);
    }

You consume everything in instream, so instream is empty. Now when try to do this,

Document doc = builder.parse(instream);

The parsing will fail, because you have passed it an empty stream.

Perhaps the volume was created via docker-compose? If so, it should get removed by:

docker-compose down --volumes

Note that the if $myVar; then ... ;fi construct has a security problem you might want to avoid with

case $myvar in
  (true)    echo "is true";;
  (false)   echo "is false";;
  (rm -rf*) echo "I just dodged a bullet";;
esac

You might also want to rethink why if [ "$myvar" = "true" ] appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case solution is also handled without forks.

The IPv6 addresses for fields like RemoteAddr from http.Request are formatted as "[::1]:53343"

So net.SplitHostPort works great:

package main

    import (
        "fmt"
        "net"
    )

    func main() {
        host1, port, err := net.SplitHostPort("127.0.0.1:5432")
        fmt.Println(host1, port, err)

        host2, port, err := net.SplitHostPort("[::1]:2345")
        fmt.Println(host2, port, err)

        host3, port, err := net.SplitHostPort("localhost:1234")
        fmt.Println(host3, port, err)
    }

Output is:

127.0.0.1 5432 <nil>
::1 2345 <nil>
localhost 1234 <nil>

If you are using Spring MVC version 5 you can set the encoding also using the @GetMapping annotation. Here is an example which sets the content type to JSON and also the encoding type to UTF-8:

@GetMapping(value="/rest/events", produces = "application/json; charset=UTF-8")

More information on the @GetMapping annotation here:

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/bind/annotation/GetMapping.html

What you are asking for is a specialized form of compression. xdelta3 was designed for this particular kind of compression, and there's a python binding for it, but you could probably get away with using zlib directly. You'd want to use zlib.compressobj and zlib.decompressobj with the zdict parameter set to your "base word", e.g. afrykanerskojezyczny.

Caveats are zdict is only supported in python 3.3 and higher, and it's easiest to code if you have the same "base word" for all your diffs, which may or may not be what you want.

You can also "sample" the same number of items in your data frame with something like this:

nr<-dim(M)[1]
random_M = M[sample.int(nr),]

If you really don't want to include top directory in the tarball (and that's generally bad idea):

tar czf workspace.tar.gz -C /path/to/workspace .

Ok, instead of identifying players by name track with sockets through which they have connected. You can have a implementation like

Server

var allClients = [];
io.sockets.on('connection', function(socket) {
   allClients.push(socket);

   socket.on('disconnect', function() {
      console.log('Got disconnect!');

      var i = allClients.indexOf(socket);
      allClients.splice(i, 1);
   });
});

Hope this will help you to think in another way

TL;DR

Most of the answers found here are correct only if you need the current year based on your local machine's time zone and offset (client side) - source which, in most scenarios, cannot be considered reliable (beause it can differ from machine to machine).

Reliable sources are:

• Web server's clock (but make sure that it's updated)
• Time APIs & CDNs

Details

A method called on the Date instance will return a value based on the local time of your machine.

Further details can be found in "MDN web docs": JavaScript Date object.

For your convenience, I've added a relevant note from their docs:

(...) the basic methods to fetch the date and time or its components all work in the local (i.e. host system) time zone and offset.

Another source mentioning this is: JavaScript date and time object

it is important to note that if someone's clock is off by a few hours or they are in a different time zone, then the Date object will create a different times from the one created on your own computer.

Some reliable sources that you can use are:

• Your web server's clock (check if it's accurate first)
• Time APIs & CDNs:
  • https://timezonedb.com/api
  • http://worldtimeapi.org
  • http://worldclockapi.com
  • http://www.geonames.org/export/ws-overview.html
  • Other related APIs: https://www.programmableweb.com/category/time/api

But if you simply don't care about the time accuracy or if your use case requires a time value relative to local machine's time then you can safely use Javascript's Date basic methods like Date.now(), or new Date().getFullYear() (for current year).

While the currently accepted answer was a huge help to me, I wanted to share some useful modifications that simplify the queries and also increase performance.

"Simple" Repeat Events

To handle events which recur at regular intervals, such as:

Repeat every other day 

or

Repeat every week on Tuesday 

You should create two tables, one called events like this:

ID    NAME
1     Sample Event
2     Another Event

And a table called events_meta like this:

ID    event_id      repeat_start       repeat_interval
1     1             1369008000         604800            -- Repeats every Monday after May 20th 2013
1     1             1369008000         604800            -- Also repeats every Friday after May 20th 2013

With repeat_start being a unix timestamp date with no time (1369008000 corresponds to May 20th 2013) , and repeat_interval an amount in seconds between intervals (604800 is 7 days).

By looping over each day in the calendar you can get repeat events using this simple query:

SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
WHERE  (( 1299736800 - repeat_start) % repeat_interval = 0 )

Just substitute in the unix-timestamp (1299736800) for each date in your calendar.

Note the use of the modulo (% sign). This symbol is like regular division, but returns the ''remainder'' instead of the quotient, and as such is 0 whenever the current date is an exact multiple of the repeat_interval from the repeat_start.

Performance Comparison

This is significantly faster than the previously suggested "meta_keys"-based answer, which was as follows:

SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
RIGHT JOIN `events_meta` EM2 ON EM2.`meta_key` = CONCAT( 'repeat_interval_', EM1.`id` )
WHERE EM1.meta_key = 'repeat_start'
    AND (
        ( CASE ( 1299132000 - EM1.`meta_value` )
            WHEN 0
              THEN 1
            ELSE ( 1299132000 - EM1.`meta_value` )
          END
        ) / EM2.`meta_value`
    ) = 1

If you run EXPLAIN this query, you'll note that it required the use of a join buffer:

+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
| id | select_type | table | type   | possible_keys | key     | key_len | ref              | rows | Extra                          |
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+
|  1 | SIMPLE      | EM1   | ALL    | NULL          | NULL    | NULL    | NULL             |    2 | Using where                    |
|  1 | SIMPLE      | EV    | eq_ref | PRIMARY       | PRIMARY | 4       | bcs.EM1.event_id |    1 |                                |
|  1 | SIMPLE      | EM2   | ALL    | NULL          | NULL    | NULL    | NULL             |    2 | Using where; Using join buffer |
+----+-------------+-------+--------+---------------+---------+---------+------------------+------+--------------------------------+

The solution with 1 join above requires no such buffer.

"Complex" Patterns

You can add support for more complex types to support these types of repeat rules:

Event A repeats every month on the 3rd of the month starting on March 3, 2011

or

Event A repeats second Friday of the month starting on March 11, 2011

Your events table can look exactly the same:

ID    NAME
1     Sample Event
2     Another Event

Then to add support for these complex rules add columns to events_meta like so:

ID    event_id      repeat_start       repeat_interval    repeat_year    repeat_month    repeat_day    repeat_week    repeat_weekday
1     1             1369008000         604800             NULL           NULL            NULL          NULL           NULL             -- Repeats every Monday after May 20, 2013
1     1             1368144000         604800             NULL           NULL            NULL          NULL           NULL             -- Repeats every Friday after May 10, 2013
2     2             1369008000         NULL               2013           *               *             2              5                -- Repeats on Friday of the 2nd week in every month    

Note that you simply need to either specify a repeat_interval or a set of repeat_year, repeat_month, repeat_day, repeat_week, and repeat_weekday data.

This makes selection of both types simultaneously very simple. Just loop through each day and fill in the correct values, (1370563200 for June 7th 2013, and then the year, month, day, week number and weekday as follows):

SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
WHERE  (( 1370563200 - repeat_start) % repeat_interval = 0 )
  OR ( 
    (repeat_year = 2013 OR repeat_year = '*' )
    AND
    (repeat_month = 6 OR repeat_month = '*' )
    AND
    (repeat_day = 7 OR repeat_day = '*' )
    AND
    (repeat_week = 2 OR repeat_week = '*' )
    AND
    (repeat_weekday = 5 OR repeat_weekday = '*' )
    AND repeat_start <= 1370563200
  )

This returns all events that repeat on the Friday of the 2nd week, as well as any events that repeat every Friday, so it returns both event ID 1 and 2:

ID    NAME
1     Sample Event
2     Another Event

*Sidenote in the above SQL I used PHP Date's default weekday indexes, so "5" for Friday

Hope this helps others as much as the original answer helped me!

Same as above, might help some people.

setTimeout(() => {
  if (pushToken!=null && deviceId!=null) {
    console.log("pushToken & OS ");
    this.setState({ pushToken: pushToken});
    this.setState({ deviceId: deviceId });
    console.log("pushToken & OS "+pushToken+"\n"+deviceId);
  }
}, 1000);

Check for any recusive calls for methods. Mainly it is caused when there is recursive call for a method. A simple example is

public static void main(String... args) {
    Main main = new Main();

    main.testMethod(1);
}

public void testMethod(int i) {
    testMethod(i);

    System.out.println(i);
}

Here the System.out.println(i); will be repeatedly pushed to stack when the testMethod is called.

1 use command

show create table test.location

2. right click on selected row and choose Open Value In Viewer

3. select tab Text

There are many good scripts above for generating insert statements, but I attempted one of my own to make it as user friendly as possible and to also be able to do UPDATE statements. + package the result ready for .sql files that can be stored by date.

It takes as input your normal SELECT statement with WHERE clause, then outputs a list of Insert statements and update statements. Together they form a sort of IF NOT EXISTS () INSERT ELSE UPDATE It is handy too when there are non-updatable columns that need exclusion from the final INSERT/UPDATE statement.

Another thing that below script can do is: it can even handle INNER JOINs with other tables as input statement for the stored proc. It can be handy as a poor man's Release management tool that sits right at your finger tips where you are typing the sql SELECT statements all day.

-------------README for the deeper interested person:
            Goal of the Stored PROCEDURE is to get updates from simple SQL SELECT statements. It is made ot be simple but fast and powerfull. As always => power is nothing without control, so check before you execute.
            Its power sits also in the fact that you can make insert statements, so combined gives you a  "IF NOT EXISTS()  INSERT "   capability. 

            The scripts work were there are primary keys or identity columns on table you want to update (/ or make inserts for).
            It will also works when no primary keys / identity column exist(s) and you define them yourselve. But then be carefull (duplicate hits can occur). When the table has a primary key it will always be used.
            The script works with a real  temporary table, made on the fly   (APPROPRIATE RIGHTS needed), to put the values inside from the script, then add 3 columns for constructing the "insert into tableX (...) values ()" ,  and the 2 update statement.
            We work with temporary structures like   "where columnname = {Columnname}" and then later do the update on that temptable for the columns values found on that same line.
                    example  "where columnname = {Columnname}"  for birthdate becomes   "where birthdate = {birthdate}" an then we find the birthdate value on that line inside the temp table.
            So then the statement becomes  "where birthdate = {19800417}"
            Enjoy releasing scripts as of now...                                        by  Pieter van Nederkassel  - freeware "CC BY-SA" (+use at own risk)

Here's my little class that can reprint blocks of text. It properly clears the previous text so you can overwrite your old text with shorter new text without creating a mess.

import re, sys

class Reprinter:
    def __init__(self):
        self.text = ''

    def moveup(self, lines):
        for _ in range(lines):
            sys.stdout.write("\x1b[A")

    def reprint(self, text):
        # Clear previous text by overwritig non-spaces with spaces
        self.moveup(self.text.count("\n"))
        sys.stdout.write(re.sub(r"[^\s]", " ", self.text))

        # Print new text
        lines = min(self.text.count("\n"), text.count("\n"))
        self.moveup(lines)
        sys.stdout.write(text)
        self.text = text

reprinter = Reprinter()

reprinter.reprint("Foobar\nBazbar")
reprinter.reprint("Foo\nbar")
