Keep in mind that with pointers to struct you'd have to dereference the variable and not compare it with a pointer to empty struct:

session := &Session{}
if (Session{}) == *session {
    fmt.Println("session is empty")
}

Check this playground.

Also here you can see that a struct holding a property which is a slice of pointers cannot be compared the same way...

$this->db1->where('tennant_id', $tennant_id);
$this->db1->order_by('id', 'DESC');
return $this->db1->get('courses')->result();

WebKit is a layout engine designed to allow web browsers to render web pages. The WebKit engine provides a set of classes to display web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited.

WebKit was originally created as a fork of KHTML as the layout engine for Apple's Safari; it is portable to many other computing platforms. It is also used in Google's Chrome Browser.

WebKit's WebCore and JavaScriptCore components are available under the GNU Lesser General Public License, and the rest of WebKit is available under a BSD-style license.

The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.

From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/

the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.

var wordOccurrences = words
                .GroupBy(w => w)
                .Select(intermediate => new
                {
                    Word = intermediate.Key,
                    Frequency = intermediate.Sum(w => 1)
                })
                .Where(w => w.Frequency > 10)
                .OrderBy(w => w.Frequency);

If you don't want any dependency on Spring's HATEOAS or javax.* namespace, use ServletUriComponentsBuilder to get URI of current request:

import org.springframework.web.util.UriComponentsBuilder;

ServletUriComponentsBuilder.fromCurrentRequest();
ServletUriComponentsBuilder.fromCurrentRequestUri();

Vladimir's answer is perfect, but anyone like me who is looking for swift solution

This Solution is Worked for swift version 4.2

var i = 0
    func animation(){
        let name = (i % 2 == 0) ? "1.png" : "2.png"
        myImageView.image = UIImage.init(named: name)
        let transition: CATransition = CATransition.init()
        transition.duration = 1.0
        transition.timingFunction = CAMediaTimingFunction.init(name: .easeInEaseOut)
        transition.type = .fade
        myImageView.layer.add(transition, forKey: nil)
        i += 1
    }

You can call this method from anywhere. It will change the image to next one(image) with animation.

For Swift Version 4.0 Use bellow solution

var i = 0
    func animationVersion4(){
        let name = (i % 2 == 0) ? "1.png" : "2.png"
        uiImage.image = UIImage.init(named: name)
        let transition: CATransition = CATransition.init()
        transition.duration = 1.0
        transition.timingFunction = CAMediaTimingFunction.init(name: kCAMediaTimingFunctionEaseInEaseOut)
        transition.type = kCATransitionFade
        uiImage.layer.add(transition, forKey: nil)
        i += 1
    }

Well, your syntax doesn't match the link you included, which specifies:

 CREATE TABLE name (column defs) 
    CONSTRAINT constraint_name    -- This is new
    UNIQUE (col_name1, col_name2) ON CONFLICT REPLACE

getActionCommand()

Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.

IMO, this is useful in case you a single command-component to fire different commands based on it's state, and using this method your handler can execute the right lines of code.

JTextField has JTextField#setActionCommand(java.lang.String) method that you can use to set the command string used for action events generated by it.

getSource()

Returns: The object on which the Event initially occurred.

We can use getSource() to identify the component and execute corresponding lines of code within an action-listener. So, we don't need to write a separate action-listener for each command-component. And since you have the reference to the component itself, you can if you need to make any changes to the component as a result of the event.

If the event was generated by the JTextField then the ActionEvent#getSource() will give you the reference to the JTextField instance itself.

If you pass None as the first argument to to_csv() the data will be returned as a string. From there it's an easy step to upload that to S3 in one go.

It should also be possible to pass a StringIO object to to_csv(), but using a string will be easier.

Another short way is to fill the minutes with a leading zero using:

String(date.getMinutes()).padStart(2, "0");

Meaning: Make the string two chars long, if a char is missing then set 0 at this position.

See docs at str.padStart(targetLength, padString)

Update the data ... change button titles..whatever stuff you have to update..

then just call

[self.view setNeedsDisplay];

sorted(list, key=lambda x: x[1])

Note: this works on time variable too.

You can access a non-Native HashTable through System.Collections.HashTable.

HashTable

Represents a collection of key/value pairs that are organized based on the hash code of the key.

Not sure you would ever want to use this over Scripting.Dictionary but adding here for the sake of completeness. You can review the methods in case there are some of interest e.g. Clone, CopyTo

Example:

Option Explicit

Public Sub UsingHashTable()

    Dim h As Object
    Set h = CreateObject("System.Collections.HashTable")
   
    h.Add "A", 1
    ' h.Add "A", 1  ''<< Will throw duplicate key error
    h.Add "B", 2
    h("B") = 2
      
    Dim keys As mscorlib.IEnumerable 'Need to cast in order to enumerate  'https://stackoverflow.com/a/56705428/6241235
    
    Set keys = h.keys
    
    Dim k As Variant
    
    For Each k In keys
        Debug.Print k, h(k)                      'outputs the key and its associated value
    Next
    
End Sub

This answer by @MathieuGuindon gives plenty of detail about HashTable and also why it is necessary to use mscorlib.IEnumerable (early bound reference to mscorlib) in order to enumerate the key:value pairs.

Since everyone else is posting their methods, I figured I'd post the extension method I usually use for this:

EDIT: added int/long variants...and fixed a copypasta typo...

public static class Ext
{
    private const long OneKb = 1024;
    private const long OneMb = OneKb * 1024;
    private const long OneGb = OneMb * 1024;
    private const long OneTb = OneGb * 1024;

    public static string ToPrettySize(this int value, int decimalPlaces = 0)
    {
        return ((long)value).ToPrettySize(decimalPlaces);
    }

    public static string ToPrettySize(this long value, int decimalPlaces = 0)
    {
        var asTb = Math.Round((double)value / OneTb, decimalPlaces);
        var asGb = Math.Round((double)value / OneGb, decimalPlaces);
        var asMb = Math.Round((double)value / OneMb, decimalPlaces);
        var asKb = Math.Round((double)value / OneKb, decimalPlaces);
        string chosenValue = asTb > 1 ? string.Format("{0}Tb",asTb)
            : asGb > 1 ? string.Format("{0}Gb",asGb)
            : asMb > 1 ? string.Format("{0}Mb",asMb)
            : asKb > 1 ? string.Format("{0}Kb",asKb)
            : string.Format("{0}B", Math.Round((double)value, decimalPlaces));
        return chosenValue;
    }
}

I would assume you tried it without adding !important?

Inline CSS (which is how JavaScript adds styling) overrides the stylesheet CSS. I'm pretty sure that's the case even when the stylesheet CSS rule has !important.

Another question (maybe a stupid question but must be asked.): Is the element you are trying to work on display:block; or display:inline-block;?

Not knowing your expertise in CSS... inline elements don't always behave as you would expect.

If you have multiple divs that you want aligned side by side at the right end of the parent div, set text-align: right; on the parent div.

I realize this question is a bit dated and since it shows up on Google search for similar issue I thought I will expand a little bit more on top of @CowWarrior's answer. I was looking for somewhat similar solution, and after scouring through countless SO question/answers and Bootstrap documentations the solution was pretty simple. Again, this would be using inbuilt Bootstrap collapse class to show/hide divs and Bootstrap's "Collapse Event".

What I realized is that it is easy to do it using a Bootstrap Accordion, but most of the time even though the functionality required is "somewhat" similar to an Accordion, it's different in a way that one would want to show hide <div> based on, lets say, menu buttons on a navbar. Below is a simple solution to this. The anchor tags (<a>) could be navbar items and based on a collapse event the corresponding div will replace the existing div. It looks slightly sloppy in CodeSnippet, but it is pretty close to achieving the functionality-

All that the JavaScript does is makes all the other <div> hide using

$(".main-container.collapse").not($(this)).collapse('hide');

when the loaded <div> is displayed by checking the Collapse event shown.bs.collapse. Here's the Bootstrap documentation on Collapse Event.

Note: main-container is just a custom class.

Here it goes-

$(".main-container.collapse").on('shown.bs.collapse', function () {    _x000D_
//when a collapsed div is shown hide all other collapsible divs that are visible_x000D_
       $(".main-container.collapse").not($(this)).collapse('hide');_x000D_
});

Just as an empty Request body is in keeping with the original purpose of a GET request and empty response body is in keeping with the original purpose of a PUT request.

When we apply local url, ErrorDocument directive expect the full path from DocumentRoot. There fore,

 ErrorDocument 404 /yourfoldernames/errors/404.html

If there are are no duplicate elements or you don't care about them, then you can use the Set class:

a1 = Set.new [5, 1, 6, 14, 2, 8]
a2 = Set.new [2, 6, 15]
a1.subset?(a2)
=> false

Behind the scenes this uses

all? { |o| set.include?(o) }

Try this

 format: 'DD/MM/YYYY hh:mm A'

As we all know JS is case-sensitive. So this will display

10/05/2016 12:00 AM

In your case is

format: 'DD/MM/YYYY'

Display : 10/05/2016

The provided answers didn't work for me. I'm adding another answer because this is where I ended up when searching for radio stream urls.

Radio Browser is a searchable site with streaming urls for radio stations around the world:

http://www.radio-browser.info/

Search for a station like FIP, Pinguin Radio or Radio Paradise, then click the save button, which downloads a PLS file that you can open in your radioplayer (Rhythmbox), or you open the file in a text editor and copy the URL to add in Goodvibes.

var url = location.href;_x000D_
var newurl = url.replace('some-domain.com','another-domain.com';);_x000D_
location.href=newurl;

See this answer https://stackoverflow.com/a/42291014/3901511

Here is an example where string equality comparison using InvariantCultureIgnoreCase and OrdinalIgnoreCase will not give the same results:

string str = "\xC4"; //A with umlaut, Ä
string A = str.Normalize(NormalizationForm.FormC);
//Length is 1, this will contain the single A with umlaut character (Ä)
string B = str.Normalize(NormalizationForm.FormD);
//Length is 2, this will contain an uppercase A followed by an umlaut combining character
bool equals1 = A.Equals(B, StringComparison.OrdinalIgnoreCase);
bool equals2 = A.Equals(B, StringComparison.InvariantCultureIgnoreCase);

If you run this, equals1 will be false, and equals2 will be true.

Just format like that:

s = "your string"; raw_s = r'{0}'.format(s)

While creating the matrix X and Y vector use values.

X=dataset.iloc[:,4].values
Y=dataset.iloc[:,0:4].values

It will definitely solve your problem.

As WhirlWind has pointed out, the recommendations to use atoi aren't really very good. atoi has no way to indicate an error, so you get the same return from atoi("0"); as you do from atoi("abc");. The first is clearly meaningful, but the second is a clear error.

He also recommended strtol, which is perfectly fine, if a little bit clumsy. Another possibility would be to use sscanf, something like:

if (1==sscanf(argv[1], "%d", &temp))
    // successful conversion
else
    // couldn't convert input

note that strtol does give slightly more detailed results though -- in particular, if you got an argument like 123abc, the sscanf call would simply say it had converted a number (123), whereas strtol would not only tel you it had converted the number, but also a pointer to the a (i.e., the beginning of the part it could not convert to a number).

Since you're using C++, you could also consider using boost::lexical_cast. This is almost as simple to use as atoi, but also provides (roughly) the same level of detail in reporting errors as strtol. The biggest expense is that it can throw exceptions, so to use it your code has to be exception-safe. If you're writing C++, you should do that anyway, but it kind of forces the issue.

See example here

This's Because!

1. The timeout function callbacks are all running well after the completion of the loop. In fact, as timers go, even if it was setTimeout(.., 0) on each iteration, all those function callbacks would still run strictly after the completion of the loop, that's why 3 was reflected!
2. all two of those functions, though they are defined separately in each loop iteration, are closed over the same shared global scope, which has, in fact, only one i in it.

the Solution's declaring a single scope for each iteration by using a self-function executed(anonymous one or better IIFE) and having a copy of i in it, like this:

for (var i = 1; i <= 2; i++) {

     (function(){

         var j = i;
         setTimeout(function() { console.log(j) }, 100);

     })();

}

the cleaner one would be

for (var i = 1; i <= 2; i++) {

     (function(i){ 

         setTimeout(function() { console.log(i) }, 100);

     })(i);

}

The use of an IIFE(self-executed function) inside each iteration created a new scope for each iteration, which gave our timeout function callbacks the opportunity to close over a new scope for each iteration, one which had a variable with the right per-iteration value in it for us to access.

You can combine your counts like you were doing before, but then you could sum them all up a number of ways, one of which is shown below:

SELECT SUM(A) 
FROM
(
    SELECT 1 AS A
    UNION ALL 
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
    UNION ALL
    SELECT 1 AS A
) AS B

In addition to the answer by ProGM, in case you see characters in boxes like NUL or ACK and want to get rid of them, those are ASCII control characters (0 to 31), you can find them with the following expression and remove them:

[\x00-\x1F]+

In order to remove all non-ASCII AND ASCII control characters, you should remove all characters matching this regex:

[^\x1F-\x7F]+

Here is a rough explanation of the concepts.

[ACK] is the acknowledgement that the previously sent data packet was received.

[FIN] is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN).

So, suppose

• host A sends a data packet to host B
• and then host B wants to close the connection.
• Host B (depending on timing) can respond with [FIN,ACK] indicating that it received the sent packet and wants to close the session.
• Host A should then respond with a [FIN,ACK] indicating that it received the termination request (the ACK part) and that it too will close the connection (the FIN part).

However, if host A wants to close the session after sending the packet, it would only send a [FIN] packet (nothing to acknowledge) but host B would respond with [FIN,ACK] (acknowledges the request and responds with FIN).

Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST] instead of the usual [FIN,ACK]. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.

You can find a more detailed and comprehensive explanation here.

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

After looking at sp_who, Oracle does not have that ability per se. Oracle has at least 8 processes running which run the db. Like RMON etc.

You can ask the DB which queries are running as that just a table query. Look at the V$ tables.

Quick Example:

SELECT sid,
       opname,
       sofar,
       totalwork,
       units,
       elapsed_seconds,
       time_remaining
FROM v$session_longops
WHERE sofar != totalwork;

Better option is to use :

{{(100*score/questionCounter) || 0 | number:0}}

It sets default value of equation to 0 in the case when values are not initialized.

try Mozilla official site: https://developer.mozilla.org/en/DOM/window.onhashchange

cite as follow:

if ("onhashchange" in window) {
    alert("The browser supports the hashchange event!");
}

function locationHashChanged() {
    if (location.hash === "#somecoolfeature") {
        somecoolfeature();
    }
}

window.onhashchange = locationHashChanged;

You have use the SqlQuery function and indicate the entity to mapping the result.

I send an example as to perform this:

var oficio= new SqlParameter
{
    ParameterName = "pOficio",
    Value = "0001"
};

using (var dc = new PCMContext())
{
    return dc.Database
             .SqlQuery<ProyectoReporte>("exec SP_GET_REPORTE @pOficio",
                                        oficio)
             .ToList();
}

Installing the Selinux from the Centos repository worked for me:
1. Go to http://mirror.centos.org/centos/7/extras/x86_64/Packages/
2. Find the latest version for container-selinux i.e. container-selinux-2.21-1.el7.noarch.rpm
3. Run the following command on your terminal: $ sudo yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/**Add_current_container-selinux_package_here**
4. The command should looks like the following $ sudo yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.21-1.el7.noarch.rpm
Note: the container version is constantly being updated, that is why you should look for the latest version in the Centos' repository

I use this method:

{% if quote.myfile %}
    <div class="">
        <a role="button" 
            href="{{ quote.myfile.url }}"
            download="{{ quote.myfile.url }}"
            class="btn btn-light text-dark ml-0">
            Download attachment
        </a>
    </div>
{% endif %}

value="<?php echo htmlspecialchars($name); ?>"

If you are not using model-first; Double click 'edmx' file ->select all and delete all entity models -> save -> right click 'update model from database ->select required tables ->finish and save.

I just ran into this problem too. In my case, I was dealing with some images that were not localized and others that were--in multiple languages. A base URL didn't get the images inside localized folders for me. I solved this by doing the following:

// make sure you have the image name and extension (for demo purposes, I'm using "myImage" and "png" for the file "myImage.png", which may or may not be localized)
NSString *imageFileName = @"myImage";
NSString *imageFileExtension = @"png";

// load the path of the image in the main bundle (this gets the full local path to the image you need, including if it is localized and if you have a @2x version)
NSString *imagePath = [[NSBundle mainBundle] pathForResource:imageFileName ofType:imageFileExtension];

// generate the html tag for the image (don't forget to use file:// for local paths)
NSString *imgHTMLTag = [NSString stringWithFormat:@"<img src=\"file://%@\" />", imagePath];

Then, use imgHTMLTag in your UIWebView HTML code when you load the contents.

I hope this helps anyone who ran into the same problem.

Clear & Simple Instructions for Rails 5 & 6

• WARNING: You will lose data if you remove a column from your database. To proceed, see below:
• Warning: the below instructions are for trivial migrations. For complex migrations with e.g. millions and millions of rows, you will have to account for the possibility of failures, you will also have to think about how to optimise your migrations so that they run swiftly, and the possibility that users will use your app while the migration process is occurring. If you have multiple databases, or if anything is remotely complicated, then don't blame me if anything goes wrong!

1. Create a migration

Run the following command in your terminal:

rails generate migration remove_fieldname_from_tablename fieldname:fieldtype

Note: the table name should be in plural form as per rails convention.

Example:

In my case I want to remove the accepted column (a boolean value) from the quotes table:

rails g migration RemoveAcceptedFromQuotes accepted:boolean

See the documentation re: a convention when adding/removing fields to a table:

There is a special syntactic shortcut to generate migrations that add fields to a table.

rails generate migration add_fieldname_to_tablename fieldname:fieldtype

2. Check the migration

# db/migrate/20190122035000_remove_accepted_from_quotes.rb
class RemoveAcceptedFromQuotes < ActiveRecord::Migration[5.2]
  # with rails 5.2 you don't need to add a separate "up" and "down" method.
  def change
    remove_column :quotes, :accepted, :boolean
  end
end

3. Run the migration

rake db:migrate or rails db:migrate (they're both the same)

....And then you're off to the races!

A simple one which works for me:

I integrate the @mattmc3 aswer. If you want to convert a xlsx file you should use this connection string (the string provided by matt works for xls formats, not xlsx):

var cnnStr = String.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0;IMEX=1;HDR=NO\"", excelFilePath);

I encountered the same issues: In a relative layout parentView, I have 2 children childView1 and childView2. At first, I put childView1 above childView2 and I want childView1 to be on top of childView2. Changing the order of children views did not solve the problem for me. What worked for me is to set android:clipChildren="false" on parentView and in the code I set:

childView1.bringToFront();

parentView.invalidate();

It is generally a bad pattern to kill a thread abruptly, in Python, and in any language. Think of the following cases:

• the thread is holding a critical resource that must be closed properly
• the thread has created several other threads that must be killed as well.

The nice way of handling this, if you can afford it (if you are managing your own threads), is to have an exit_request flag that each thread checks on a regular interval to see if it is time for it to exit.

For example:

import threading

class StoppableThread(threading.Thread):
    """Thread class with a stop() method. The thread itself has to check
    regularly for the stopped() condition."""

    def __init__(self,  *args, **kwargs):
        super(StoppableThread, self).__init__(*args, **kwargs)
        self._stop_event = threading.Event()

    def stop(self):
        self._stop_event.set()

    def stopped(self):
        return self._stop_event.is_set()

In this code, you should call stop() on the thread when you want it to exit, and wait for the thread to exit properly using join(). The thread should check the stop flag at regular intervals.

There are cases, however, when you really need to kill a thread. An example is when you are wrapping an external library that is busy for long calls, and you want to interrupt it.

The following code allows (with some restrictions) to raise an Exception in a Python thread:

def _async_raise(tid, exctype):
    '''Raises an exception in the threads with id tid'''
    if not inspect.isclass(exctype):
        raise TypeError("Only types can be raised (not instances)")
    res = ctypes.pythonapi.PyThreadState_SetAsyncExc(ctypes.c_long(tid),
                                                     ctypes.py_object(exctype))
    if res == 0:
        raise ValueError("invalid thread id")
    elif res != 1:
        # "if it returns a number greater than one, you're in trouble,
        # and you should call it again with exc=NULL to revert the effect"
        ctypes.pythonapi.PyThreadState_SetAsyncExc(ctypes.c_long(tid), None)
        raise SystemError("PyThreadState_SetAsyncExc failed")

class ThreadWithExc(threading.Thread):
    '''A thread class that supports raising an exception in the thread from
       another thread.
    '''
    def _get_my_tid(self):
        """determines this (self's) thread id

        thread, to get the identity of the thread represented by this
        instance.
        """
        if not self.isAlive():
            raise threading.ThreadError("the thread is not active")

        # do we have it cached?
        if hasattr(self, "_thread_id"):
            return self._thread_id

        # no, look for it in the _active dict
        for tid, tobj in threading._active.items():
            if tobj is self:
                self._thread_id = tid
                return tid

        # TODO: in python 2.6, there's a simpler way to do: self.ident

        raise AssertionError("could not determine the thread's id")

    def raiseExc(self, exctype):
        """Raises the given exception type in the context of this thread.

        If you are sure that your exception should terminate the thread,
        one way to ensure that it works is:

            t = ThreadWithExc( ... )
            ...
            t.raiseExc( SomeException )
            while t.isAlive():
                time.sleep( 0.1 )
                t.raiseExc( SomeException )

        check that your thread has caught it.

        caller thread, to raise an exception in the context of the
        thread represented by this instance.
        """
        _async_raise( self._get_my_tid(), exctype )

(Based on Killable Threads by Tomer Filiba. The quote about the return value of PyThreadState_SetAsyncExc appears to be from an old version of Python.)

As noted in the documentation, this is not a magic bullet because if the thread is busy outside the Python interpreter, it will not catch the interruption.

A good usage pattern of this code is to have the thread catch a specific exception and perform the cleanup. That way, you can interrupt a task and still have proper cleanup.

Matlab and Scilab languages offer a simpler and more elegant syntax than Python for the question you're asking, so I think the best you can do is to mimic Matlab/Scilab by using the Numpy package in Python. By doing this the solution to your problem is very concise and elegant:

from numpy import *
property_a = array([545., 656., 5.4, 33.])
property_b = array([ 1.2,  1.3, 2.3, 0.3])
good_objects = [True, False, False, True]
good_indices = [0, 3]
property_asel = property_a[good_objects]
property_bsel = property_b[good_indices]

Numpy tries to mimic Matlab/Scilab but it comes at a cost: you need to declare every list with the keyword "array", something which will overload your script (this problem doesn't exist with Matlab/Scilab). Note that this solution is restricted to arrays of number, which is the case in your example.

I need to sum the span elements so I edited Akhil Sekharan's answer below.

var arr = document.querySelectorAll('span[id^="score"]');
var total=0;
    for(var i=0;i<arr.length;i++){
        if(parseInt(arr[i].innerHTML))
            total+= parseInt(arr[i].innerHTML);
    }
console.log(total)

You can change the elements with other elements link will guide you with editing.

https://www.w3.org/TR/css3-selectors/#attribute-substrings

Alternatively you can use ljust/rjust to make the formatting nicer.

print "%s%s" % (str(count).rjust(10), conv)

or

print str(count).ljust(10), conv

You could use complete unix paths like:

PATH=$PATH:/c/python26
git config --global merge.tool meld
git config --global mergetool.meld.path /c/Program files (x86)/meld/bin/meld

This is what is described in "How to get meld working with git on Windows"

Or you can adopt the wrapper approach described in "Use Meld with Git on Windows"

# set up Meld as the default gui diff tool
$ git config --global  diff.guitool meld

# set the path to Meld
$ git config --global mergetool.meld.path C:/meld-1.6.0/Bin/meld.sh

With a script meld.sh:

#!/bin/env bash
C:/Python27/pythonw.exe C:/meld-1.6.0/bin/meld $@

abergmeier mentions in the comments:

I had to do:

git config --global merge.tool meld
git config --global mergetool.meld.path /c/Program files (x86)/Meld/meld/meldc.exe

Note that meldc.exe was especially created to be invoked on Windows via console. Thus meld.exe will not work properly.

CenterOrbit mentions in the comments for Mac OS to install homebrew, and then:

brew cask install meld
git config --global merge.tool meld
git config --global  diff.guitool meld

Have you checked the docstring of write()? It says:

write(str) -> None. Write string str to file.

Note that due to buffering, flush() or close() may be needed before the file on disk reflects the data written.

So you need to convert y to str first.

Also note that the string will be written at the current position which will be at the end of the file, because you'll already have read the old value. Use f.seek(0) to get to the beginning of the file.`

Edit: As for the IOError, this issue seems related. A cite from there:

For the modes where both read and writing (or appending) are allowed (those which include a "+" sign), the stream should be flushed (fflush) or repositioned (fseek, fsetpos, rewind) between either a reading operation followed by a writing operation or a writing operation followed by a reading operation.

So, I suggest you try f.seek(0) and maybe the problem goes away.

Per the iterated solutions via comments in the selected answer...

In Python 3:

max(stats.keys(), key=(lambda k: stats[k]))

In Python 2:

max(stats.iterkeys(), key=(lambda k: stats[k]))

You can add the meta tag:

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

A brief explanation on what it is and how it works is found on this link.

Both T1 and T2 can refer to a class containing this variable.
You can then make this variable volatile, and this means that
Changes to that variable are immediately visible in both threads.

See this article for more info.

Volatile variables share the visibility features of synchronized but none of the atomicity features. This means that threads will automatically see the most up-to-date value for volatile variables. They can be used to provide thread safety, but only in a very restricted set of cases: those that do not impose constraints between multiple variables or between a variable's current value and its future values.

And note the pros/cons of using volatile vs more complex means of sharing state.

What you are looking for is called covariant type parameters. This means that if one type of object can be substituted for another in a method (for instance, Animal can be replaced with Dog), the same applies to expressions using those objects (so List<Animal> could be replaced with List<Dog>). The problem is that covariance is not safe for mutable lists in general. Suppose you have a List<Dog>, and it is being used as a List<Animal>. What happens when you try to add a Cat to this List<Animal> which is really a List<Dog>? Automatically allowing type parameters to be covariant breaks the type system.

It would be useful to add syntax to allow type parameters to be specified as covariant, which avoids the ? extends Foo in method declarations, but that does add additional complexity.

I used

btn.setBackgroundColor(Color.TRANSPARENT);

and

android:background="@android:color/transparent"

<br> works just fine in HTML5. HTML5 allows a little more leeway than XHTML.

Suppose A is your integer then (int)A, means casting the number to an integer and will be the integer part, the other is (A - (int)A)*10^n, here n is the number of decimals to keep.

I prefer the PHPMailer tool as it doesn't require PEAR. But either way, you have a misunderstanding: you don't want a PHP-server-wide setting for the SMTP user and password. This should be a per-app (or per-page) setting. If you want to use the same account across different PHP pages, add it to some kind of settings.php file.

Sadly, Python doesn't have a simple way to flatten lists. Try this:

def flatten(some_list):
    for element in some_list:
        if type(element) in (tuple, list):
            for item in flatten(element):
                yield item
        else:
            yield element

Which will recursively flatten a list; you can then do

result = []
[ result.extend(el) for el in x] 

for el in flatten(result):
      print el

function limitText($string,$limit){
        if(strlen($string) > $limit){
                $string = substr($string, 0,$limit) . "...";
        }
        return $string;
}

this will return 20 words. I hope it will help

I had this issue while running MySQL on Minikube (Ubuntu box) and I solved it with:

sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.mysqld

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

Comments work fine in any of the usual Java/Groovy forms, but you can't currently use groovydoc to process your Jenkinsfile (s).

First, groovydoc chokes on files without extensions with the wonderful error

... and second, as far as I can tell Javadoc-style commments at the start of a groovy script are ignored. So even if you copy/rename your Jenkinsfile to Jenkinsfile.groovy, you won't get much useful output.

I want to be able to use a

/**
 * Document my Jenkinsfile's overall purpose here
 */

comment at the start of my Jenkinsfile. No such luck (yet).

groovydoc will process classes and methods defined in your Jenkinsfile if you pass -private to the command, though.

i faced the same problem but i solved it by moving the chromedriver to this path '/opt/google/chrome/'

and this code works correctly

from selenium.webdriver import Chrome
driver = Chrome('/opt/google/chrome/chromedrive')
driver.get('https://google.com')

git config --global core.longpaths true

The above command worked for me. Using '--system' gave me config file not locked error

Go to: chrome://flags/

Enable: Allow invalid certificates for resources loaded from localhost.

You don't have the green security, but you are always allowed for https://localhost in chrome.

Suppose you store float value in "X" and you are storing integer value in "Y".

Var Y = Int(x);

or

var myIntValue = Int(myFloatValue)

All above answer is correct but in my case There is no lib folder available in my app directory and I am trying to call below line in app gradle file

 compile fileTree(include: ['*.jar'], dir: 'libs')

So make sure what ever dependency you declare in gradle file in available for app

So to put it all together, checking for Nan, infinity and complex numbers (it would seem they are specified with j, not i, i.e. 1+2j) it results in:

def is_number(s):
    try:
        n=str(float(s))
        if n == "nan" or n=="inf" or n=="-inf" : return False
    except ValueError:
        try:
            complex(s) # for complex
        except ValueError:
            return False
    return True

Modern browsers do not currently implement JSONRequest (as far as I know) since it is only a draft right now. I have found someone who has implemented it as a library that you can include in your page: http://devpro.it/JSON/files/JSONRequest-js.html (please note that it has a few dependencies).

Otherwise, you might want to go with another JS library like jQuery or Mootools.

I have placed here complete bins for above query. you can check demo link too.

If you just need an int to a string as you suggest, I've found the easiest way is to do as below:

[NSString stringWithFormat:@"%d",numberYouAreTryingToConvert]

I ran into this problem while upgrading to WordPress 4.0. By default WordPress limits the maximum execution time to 30 seconds.

Add the following code to your .htaccess file on your root directory of your WordPress Installation to over-ride the default.

php_value max_execution_time 300  //where 300 = 300 seconds = 5 minutes

List membersList = Arrays.asList(membersArray);

returns immutable list, what you need to do is

new ArrayList<>(Arrays.asList(membersArray)); to make it mutable

In my case, when laravel generated the .env configuration file, laravel also generated two uncommented "DB_HOST" lines at line 11 and 12, delete the one that says "mysql" and uncomment (if yours it's commented) the other one (the one with the localhost ip 127.0.0.1) and it worked. (In my case).

Have a great day

Update:

I have added this link to my other answer how to use JWT authentication for ASP.NET Web API here for anyone interested in JWT.

We have managed to apply HMAC authentication to secure Web API, and it worked okay. HMAC authentication uses a secret key for each consumer which both consumer and server both know to hmac hash a message, HMAC256 should be used. Most of the cases, hashed password of the consumer is used as a secret key.

The message normally is built from data in the HTTP request, or even customized data which is added to HTTP header, the message might include:

1. Timestamp: time that request is sent (UTC or GMT)
2. HTTP verb: GET, POST, PUT, DELETE.
3. post data and query string,
4. URL

Under the hood, HMAC authentication would be:

Consumer sends a HTTP request to web server, after building the signature (output of hmac hash), the template of HTTP request:

User-Agent: {agent}   
Host: {host}   
Timestamp: {timestamp}
Authentication: {username}:{signature}

Example for GET request:

GET /webapi.hmac/api/values

User-Agent: Fiddler    
Host: localhost    
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

The message to hash to get signature:

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n

Example for POST request with query string (signature below is not correct, just an example)

POST /webapi.hmac/api/values?key2=value2

User-Agent: Fiddler    
Host: localhost    
Content-Type: application/x-www-form-urlencoded
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

key1=value1&key3=value3

The message to hash to get signature

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n
key1=value1&key2=value2&key3=value3

Please note that form data and query string should be in order, so the code on the server get query string and form data to build the correct message.

When HTTP request comes to the server, an authentication action filter is implemented to parse the request to get information: HTTP verb, timestamp, uri, form data and query string, then based on these to build signature (use hmac hash) with the secret key (hashed password) on the server.

The secret key is got from the database with the username on the request.

Then server code compares the signature on the request with the signature built; if equal, authentication is passed, otherwise, it failed.

The code to build signature:

private static string ComputeHash(string hashedPassword, string message)
{
    var key = Encoding.UTF8.GetBytes(hashedPassword.ToUpper());
    string hashString;

    using (var hmac = new HMACSHA256(key))
    {
        var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(message));
        hashString = Convert.ToBase64String(hash);
    }

    return hashString;
}

So, how to prevent replay attack?

Add constraint for the timestamp, something like:

servertime - X minutes|seconds  <= timestamp <= servertime + X minutes|seconds 

(servertime: time of request coming to server)

And, cache the signature of the request in memory (use MemoryCache, should keep in the limit of time). If the next request comes with the same signature with the previous request, it will be rejected.

The demo code is put as here: https://github.com/cuongle/Hmac.WebApi

You can use: Request::url() to obtain the current URL, here is an example:

@if(Request::url() === 'your url here')
    // code
@endif

Laravel offers a method to find out, whether the URL matches a pattern or not

if (Request::is('admin/*'))
{
    // code
}

Check the related documentation to obtain different request information: http://laravel.com/docs/requests#request-information

I am a quite newbie to python and I was having same issue. (windows x64 os) I have solved, doing below steps

1. I removed python (x64 version) and pygame
2. I have downloaded and installed python 2.6.6 x86: https://www.python.org/ftp/python/2.6.6/python-2.6.6.msi
3. I have downloaded and installed pygame (when installing, I have chosen the directory that I installed python): http://pygame.org/ftp/pygame-1.9.1.win32-py2.6.msi
4. Works well :)

An alternative to finding the index after the fact is to wrap the Enumerable, somewhat similar to using the Linq GroupBy() method.

public static class IndexedEnumerable
{
    public static IndexedEnumerable<T> ToIndexed<T>(this IEnumerable<T> items)
    {
        return IndexedEnumerable<T>.Create(items);
    }
}

public class IndexedEnumerable<T> : IEnumerable<IndexedEnumerable<T>.IndexedItem>
{
    private readonly IEnumerable<IndexedItem> _items;

    public IndexedEnumerable(IEnumerable<IndexedItem> items)
    {
        _items = items;
    }

    public class IndexedItem
    {
        public IndexedItem(int index, T value)
        {
            Index = index;
            Value = value;
        }

        public T Value { get; private set; }
        public int Index { get; private set; }
    }

    public static IndexedEnumerable<T> Create(IEnumerable<T> items)
    {
        return new IndexedEnumerable<T>(items.Select((item, index) => new IndexedItem(index, item)));
    }

    public IEnumerator<IndexedItem> GetEnumerator()
    {
        return _items.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return GetEnumerator();
    }
}

Which gives a use case of:

var items = new[] {1, 2, 3};
var indexedItems = items.ToIndexed();
foreach (var item in indexedItems)
{
    Console.WriteLine("items[{0}] = {1}", item.Index, item.Value);
}

Unfortunately SQL Developer doesn't fully honour the set echo off command that would (appear to) solve this in SQL*Plus.

The only workaround I've found for this is to save what you're doing as a script, e.g. test.sql with:

set echo off
spool c:\test.csv 
select /*csv*/ username, user_id, created from all_users;
spool off;

And then from SQL Developer, only have a call to that script:

@test.sql

And run that as a script (F5).

Saving as a script file shouldn't be much of a hardship anyway for anything other than an ad hoc query; and running that with @ instead of opening the script and running it directly is only a bit of a pain.

A bit of searching found the same solution on the SQL Developer forum, and the development team suggest it's intentional behaviour to mimic what SQL*Plus does; you need to run a script with @ there too in order to hide the query text.

This trick only requires one command: type net session into the command prompt.

If you are NOT an admin, you get an access is denied message.

System error 5 has occurred.

Access is denied.

If you ARE an admin, you get a different message, the most common being:

There are no entries in the list.

From MS Technet:

Used without parameters, net session displays information about all sessions with the local computer.

I solved this problem instantiating a new Date object in node.js:...

In Javascript, send the Date().toISOString() to nodejs:...

var start_date = new Date(2012, 01, 03, 8, 30);

$.ajax({
    type: 'POST',
    data: { start_date: start_date.toISOString() },
    url: '/queryScheduleCollection',
    dataType: 'JSON'
}).done(function( response ) { ... });

Then use the ISOString to create a new Date object in nodejs:..

exports.queryScheduleCollection = function(db){
    return function(req, res){

        var start_date = new Date(req.body.start_date);

        db.collection('schedule_collection').find(
            { start_date: { $gte: start_date } }
        ).toArray( function (err,d){
            ...
            res.json(d)
        })
    }
};

Note: I'm using Express and Mongoskin.

In Oracle, there is the concept of schema name, so try using this

update schemname.tablename t
set t.columnname = replace(t.columnname, t.oldvalue, t.newvalue);

Although standard C++ has no such requirement, some compilers require that all function and class templates need to be made available in every translation unit they are used. In effect, for those compilers, the bodies of template functions must be made available in a header file. To repeat: that means those compilers won't allow them to be defined in non-header files such as .cpp files

There is an export keyword which is supposed to mitigate this problem, but it's nowhere close to being portable.

You can also try this approach save the keys and values in different list and then use dict method

data=['test1', '1', 'test2', '2', 'test3', '3', 'test4', '4']

keys=[]
values=[]
for i,j in enumerate(data):
    if i%2==0:
        keys.append(j)
    else:
        values.append(j)

print(dict(zip(keys,values)))

output:

{'test3': '3', 'test1': '1', 'test2': '2', 'test4': '4'}

My Moving Average function, without numpy function:

from __future__ import division  # must be on first line of script

class Solution:
    def Moving_Avg(self,A):
        m = A[0]
        B = []
        B.append(m)
        for i in range(1,len(A)):
            m = (m * i + A[i])/(i+1)
            B.append(m)
        return B

Assuming your dataframe is mydf:

mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))

ArrayList<String> alphabetList = new ArrayList<String>();
alphabetList.add("A"); // 0 index
alphabetList.add("B"); // 1 index
alphabetList.add("C"); // 2 index
alphabetList.add("D"); // 3 index
alphabetList.add("E"); // 4 index
alphabetList.add("F"); // 5 index
alphabetList.add("G"); // 6 index
alphabetList.add("H"); // 7 index
alphabetList.add("I"); // 8 index

int position = -1;
position = alphabetList.indexOf("H");
if (position == -1) {
    Log.e(TAG, "Object not found in List");
} else {
    Log.i(TAG, "" + position);
}

Output: List Index : 7

If you pass H it will return 7, if you pass J it will return -1 as we defined default value to -1.

Done

You can omit tel number for letting user just choose from contacts, but inserting your sms text in the body. Code is for Xamarin Android:

    var uri = Uri.Parse("smsto:"); //append your number here for explicit nb
    var intent = new Intent(Intent.ActionSendto, uri);
    intent.PutExtra("sms_body", text);
    Context.StartActivity(intent);

where

Context is Xamarin.Essentials.Platform.CurrentActivity ?? Application.Context

function fix_table_header_position(){
 var width_list = [];
 $("th").each(function(){
    width_list.push($(this).width());
 });
 $("tr:first").css("position", "absolute");
 $("tr:first").css("z-index", "1000");
 $("th, td").each(function(index){
    $(this).width(width_list[index]);
 });

 $("tr:first").after("<tr height=" + $("tr:first").height() + "></tr>");}

This is my solution

An example of how to do this using a lambda expression would be:

issublist = lambda x, y: 0 in [_ in x for _ in y]

Both functions are used to move to the next Scanner token.

The difference lies in how the scanner token is generated

next() generates scanner tokens using delimiter as White Space

nextLine() generates scanner tokens using delimiter as '\n' (i.e Enter key presses)

To validate all dynamically generated elements could add a special class to each of these elements and use each() function, something like

$("#DivIdContainer .classToValidate").each(function () {
    $(this).rules('add', {
        required: true
    });
});

In a truly optimized implementation, the method for choosing pivot should depend on the array size - for a large array, it pays off to spend more time choosing a good pivot. Without doing a full analysis, I would guess "middle of O(log(n)) elements" is a good start, and this has the added bonus of not requiring any extra memory: Using tail-call on the larger partition and in-place partitioning, we use the same O(log(n)) extra memory at almost every stage of the algorithm.

The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.

UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

console.log(JSON.stringify(data)) will do what you need. I'm assuming that you're using jQuery based on your code.

If you're wanting those two particular values, you can just access those and pass them to log.

console.log(data.input_data['quantity-row_122']); 
console.log(data.input_data['price-row_122']); 

I dissent from both the answers. Don't create a reference at all, but use late binding:

  Dim objExcelApp As Object
  Dim wb As Object

  Sub Initialize()
    Set objExcelApp = CreateObject("Excel.Application")
  End Sub

  Sub ProcessDataWorkbook()
     Set wb = objExcelApp.Workbooks.Open("path to my workbook")
     Dim ws As Object
     Set ws = wb.Sheets(1)

     ws.Cells(1, 1).Value = "Hello"
     ws.Cells(1, 2).Value = "World"

     'Close the workbook
     wb.Close
     Set wb = Nothing
  End Sub

You will note that the only difference in the code above is that the variables are all declared as objects and you instantiate the Excel instance with CreateObject().

This code will run no matter what version of Excel is installed, while using a reference can easily cause your code to break if there's a different version of Excel installed, or if it's installed in a different location.

Also, the error handling could be added to the code above so that if the initial instantiation of the Excel instance fails (say, because Excel is not installed or not properly registered), your code can continue. With a reference set, your whole Access application will fail if Excel is not installed.

A dangling pointer points to memory that has already been freed. The storage is no longer allocated. Trying to access it might cause a Segmentation fault.

Common way to end up with a dangling pointer:

char *func()
{
   char str[10];
   strcpy(str, "Hello!");
   return str; 
}
//returned pointer points to str which has gone out of scope. 

You are returning an address which was a local variable, which would have gone out of scope by the time control was returned to the calling function. (Undefined behaviour)

Another common dangling pointer example is an access of a memory location via pointer, after free has been explicitly called on that memory.

int *c = malloc(sizeof(int));
free(c);
*c = 3; //writing to freed location!

A memory leak is memory which hasn't been freed, there is no way to access (or free it) now, as there are no ways to get to it anymore. (E.g. a pointer which was the only reference to a memory location dynamically allocated (and not freed) which points somewhere else now.)

void func(){
    char *ch = malloc(10);
}
//ch not valid outside, no way to access malloc-ed memory

Char-ptr ch is a local variable that goes out of scope at the end of the function, leaking the dynamically allocated 10 bytes.

A function which works in both bash and zsh:

# Return the first pathname in $PATH for name in $1
function cmd_path () {
  if [[ $ZSH_VERSION ]]; then
    whence -cp "$1" 2> /dev/null
  else  # bash
     type -P "$1"  # No output if not in $PATH
  fi
}

Non-zero is returned if the command is not found in $PATH.

You can use Regular Expression for Sanitization. Inside filter before calling chain.doFilter(request, response) method, call this code. Here is Sample Code:

for (Enumeration en = request.getParameterNames(); en.hasMoreElements(); ) {
String name = (String)en.nextElement();
String values[] = request.getParameterValues(name);
int n = values.length;
    for(int i=0; i < n; i++) {
     values[i] = values[i].replaceAll("[^\\dA-Za-z ]","").replaceAll("\\s+","+").trim();   
    }
}

Use kafka-consumer-groups.sh

For example

bin/kafka-consumer-groups.sh  --list --bootstrap-server localhost:9092

bin/kafka-consumer-groups.sh --describe --group mygroup --bootstrap-server localhost:9092

The problem happens when a floated element is within a container box, that element does not automatically force the container’s height adjust to the floated element. When an element is floated, its parent no longer contains it because the float is removed from the flow. You can use 2 methods to fix it:

• { clear: both; }
• clearfix

Once you understand what is happening, use the method below to “clearfix” it.

.clearfix:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

.clearfix {
    display: inline-block;
}

html[xmlns] .clearfix {
    display: block;
}

* html .clearfix {
    height: 1%;
}

Demonstration :)

@keyframes spin {
    from {transform:rotate(0deg);}
    to {transform:rotate(360deg);}
}

this will make you to answer the question

Here is an overview in a table format in order to show the differences between Pool.apply, Pool.apply_async, Pool.map and Pool.map_async. When choosing one, you have to take multi-args, concurrency, blocking, and ordering into account:

                  | Multi-args   Concurrence    Blocking     Ordered-results
---------------------------------------------------------------------
Pool.map          | no           yes            yes          yes
Pool.map_async    | no           yes            no           yes
Pool.apply        | yes          no             yes          no
Pool.apply_async  | yes          yes            no           no
Pool.starmap      | yes          yes            yes          yes
Pool.starmap_async| yes          yes            no           no

Notes:

• Pool.imap and Pool.imap_async – lazier version of map and map_async.

• Pool.starmap method, very much similar to map method besides it acceptance of multiple arguments.

• Async methods submit all the processes at once and retrieve the results once they are finished. Use get method to obtain the results.

• Pool.map(or Pool.apply)methods are very much similar to Python built-in map(or apply). They block the main process until all the processes complete and return the result.

Examples:

map

Is called for a list of jobs in one time

results = pool.map(func, [1, 2, 3])

apply

Can only be called for one job

for x, y in [[1, 1], [2, 2]]:
    results.append(pool.apply(func, (x, y)))

def collect_result(result):
    results.append(result)

map_async

Is called for a list of jobs in one time

pool.map_async(func, jobs, callback=collect_result)

apply_async

Can only be called for one job and executes a job in the background in parallel

for x, y in [[1, 1], [2, 2]]:
    pool.apply_async(worker, (x, y), callback=collect_result)

starmap

Is a variant of pool.map which support multiple arguments

pool.starmap(func, [(1, 1), (2, 1), (3, 1)])

starmap_async

A combination of starmap() and map_async() that iterates over iterable of iterables and calls func with the iterables unpacked. Returns a result object.

pool.starmap_async(calculate_worker, [(1, 1), (2, 1), (3, 1)], callback=collect_result)

Here is an example that lists all the files on my desktop. you should change the path variable to your path.

Instead of printing the file's name with System.out.println, you should place your own code to operate on the file.

public static void main(String[] args) {
    File path = new File("c:/documents and settings/Zachary/desktop");

    File [] files = path.listFiles();
    for (int i = 0; i < files.length; i++){
        if (files[i].isFile()){ //this line weeds out other directories/folders
            System.out.println(files[i]);
        }
    }
}

git version: 2.74

This is how I do it:

git remote add [REMOTE-NAME] [REMOTE-URL]
git fetch [REMOTE-NAME] -- [BRANCH]

Here, you have two options to do this :-

1.You can use the unary plus to convert string number into integer.

2.You can also achieve this via parsing the number into corresponding type. i.e parseInt(), parseFloat() etc

.

Now I am going to show you here with the help of examples(Find the sum of two numbers).

Using unary plus operator

<!DOCTYPE html>
<html>
<body>

<H1>Program for sum of two numbers.</H1>
<p id="myId"></p>
<script>
var x = prompt("Please enter the first number.");//prompt will always return string value
var y = prompt("Please enter the second nubmer.");
var z = +x + +y;    
document.getElementById("myId").innerHTML ="Sum of "+x+" and "+y+" is "+z;
</script>
</body>
</html>

Using parsing approach-

<!DOCTYPE html>
<html>
<body>

<H1>Program for sum of two numbers.</H1>
<p id="myId"></p>
<script>
var x = prompt("Please enter the first number.");
var y = prompt("Please enter the second number.");   
var z = parseInt(x) + parseInt(y);
document.getElementById("myId").innerHTML ="Sum of "+x+" and "+y+" is "+z;
</script>
</body>
</html>

the problem with:

std::string y("Hello worl");
y.push_back('d')
std::cout << y;

is that you have to have the 'd' as opposed to using a name of a char, like char d = 'd'; Or am I wrong?

Try below Alphanumeric regex

"^[a-zA-Z0-9]*$"

^ - Start of string

[a-zA-Z0-9]* - multiple characters to include

$ - End of string

See more: http://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

there you go

date('d.m.Y',strtotime("-1 days"));

this will work also if month change

Update: Turns out that this method, while following STL idioms well, is actually surprisingly inefficient! Don't do this with large files. (See: http://insanecoding.blogspot.com/2011/11/how-to-read-in-file-in-c.html)

You can make a streambuf iterator out of the file and initialize the string with it:

#include <string>
#include <fstream>
#include <streambuf>

std::ifstream t("file.txt");
std::string str((std::istreambuf_iterator<char>(t)),
                 std::istreambuf_iterator<char>());

Not sure where you're getting the t.open("file.txt", "r") syntax from. As far as I know that's not a method that std::ifstream has. It looks like you've confused it with C's fopen.

Edit: Also note the extra parentheses around the first argument to the string constructor. These are essential. They prevent the problem known as the "most vexing parse", which in this case won't actually give you a compile error like it usually does, but will give you interesting (read: wrong) results.

Following KeithB's point in the comments, here's a way to do it that allocates all the memory up front (rather than relying on the string class's automatic reallocation):

#include <string>
#include <fstream>
#include <streambuf>

std::ifstream t("file.txt");
std::string str;

t.seekg(0, std::ios::end);   
str.reserve(t.tellg());
t.seekg(0, std::ios::beg);

str.assign((std::istreambuf_iterator<char>(t)),
            std::istreambuf_iterator<char>());

Apart from all obvious reasons mentioned earlier, there might be another one: you didn't put an Authorize attribute on top of your controller, like that:

[Authorize(Roles = "myRole")]
[EnableCors(origins: "http://localhost:8080", headers: "*", methods: "*", SupportsCredentials = true)]
public class MyController : ApiController

At least that's what worked for me.

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )
  

You've returned a pointer to a local variable. That's bad even if threads aren't involved.

The usual way to do this, when the thread that starts is the same thread that joins, would be to pass a pointer to an int, in a location managed by the caller, as the 4th parameter of pthread_create. This then becomes the (only) parameter to the thread's entry-point. You can (if you like) use the thread exit value to indicate success:

#include <pthread.h>
#include <stdio.h>

int something_worked(void) {
    /* thread operation might fail, so here's a silly example */
    void *p = malloc(10);
    free(p);
    return p ? 1 : 0;
}

void *myThread(void *result)
{
   if (something_worked()) {
       *((int*)result) = 42;
       pthread_exit(result);
   } else {
       pthread_exit(0);
   }
}

int main()
{
   pthread_t tid;
   void *status = 0;
   int result;

   pthread_create(&tid, NULL, myThread, &result);
   pthread_join(tid, &status);

   if (status != 0) {
       printf("%d\n",result);
   } else {
       printf("thread failed\n");
   }

   return 0;
}

If you absolutely have to use the thread exit value for a structure, then you'll have to dynamically allocate it (and make sure that whoever joins the thread frees it). That's not ideal, though.

See the Create a video slideshow from images – FFmpeg

If your video does not show the frames correctly If you encounter problems, such as the first image is skipped or only shows for one frame, then use the fps video filter instead of -r for the output framerate

ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4

Alternatively the format video filter can be added to the filter chain to replace -pix_fmt yuv420p like "fps=25,format=yuv420p". The advantage of this method is that you can control which filter goes first

ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf "fps=25,format=yuv420p" out.mp4

I tested below parameters, it worked for me

"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -vf "fps=25,format=yuv420p" e:\out.mp4

below parameters also worked but it always skips the first image

"e:\ffmpeg\ffmpeg.exe" -r 1/5 -start_number 0 -i "E:\images\01\padlock%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p e:\out.mp4

making a video from images placed in different folders

First, add image paths to imagepaths.txt like below.

# this is a comment details https://trac.ffmpeg.org/wiki/Concatenate

file 'E:\images\png\images__%3d.jpg'
file 'E:\images\jpg\images__%3d.jpg'

Sample usage as follows;

"h:\ffmpeg\ffmpeg.exe" -y -r 1/5 -f concat -safe 0 -i "E:\images\imagepaths.txt" -c:v libx264 -vf "fps=25,format=yuv420p" "e:\out.mp4"

-safe 0 parameter prevents Unsafe file name error

You weren't far from the result! This does it:

awk '{NF--; print $NF}' file

This decrements the number of fields in one, so that $NF contains the former penultimate.

Test

Let's generate some numbers and print them on groups of 5:

$ seq 12 | xargs -n5
1 2 3 4 5
6 7 8 9 10
11 12

Let's print the penultimate on each line:

$ seq 12 | xargs -n5 | awk '{NF--; print $NF}'
4
9
11

Solution

You are missing an echo. Each time that you want to show the value of a variable to HTML you need to echo it.

<input type="text" name="idtest" value="<?php echo $idtest; ?>" >

Note: Depending on the value, your echo is the function you use to escape it like htmlspecialchars.

You could do something like this:

i={'foo':'bar', 'baz':'huh?'}
keys=i.keys()  #in python 3, you'll need `list(i.keys())`
values=i.values()
print keys[values.index("bar")]  #'foo'

However, any time you change your dictionary, you'll need to update your keys,values because dictionaries are not ordered in versions of Python prior to 3.7. In these versions, any time you insert a new key/value pair, the order you thought you had goes away and is replaced by a new (more or less random) order. Therefore, asking for the index in a dictionary doesn't make sense.

As of Python 3.6, for the CPython implementation of Python, dictionaries remember the order of items inserted. As of Python 3.7+ dictionaries are ordered by order of insertion.

Also note that what you're asking is probably not what you actually want. There is no guarantee that the inverse mapping in a dictionary is unique. In other words, you could have the following dictionary:

d={'i':1, 'j':1}

In that case, it is impossible to know whether you want i or j and in fact no answer here will be able to tell you which ('i' or 'j') will be picked (again, because dictionaries are unordered). What do you want to happen in that situation? You could get a list of acceptable keys ... but I'm guessing your fundamental understanding of dictionaries isn't quite right.

input.Replace("\r\n", "\n").Replace("\r", "\n").Replace("\n", "\r\n")

This will work if the input contains only one type of line breaks - either CR, or LF, or CR+LF.

Based on xcopy help, I tried and found that following works perfectly for me (tried on Win 7)

xcopy C:\folder1 C:\folder2\folder1 /E /C /I /Q /G /H /R /K /Y /Z /J

After trying all the other suggestions posted here, I discovered the solution for me was to remove the following section from the .csproj file:

  <ItemGroup>
    <Service Include="{808359B6-6B82-4DF5-91FF-3FCBEEBAD811}" />
  </ItemGroup>

Apparently this service from the original project (unavailable on local machine) was halting the entire build process, even though it wasn't essential for compilation.

Java 9+:

private byte[] loadPEM(String resource) throws IOException {
    URL url = getClass().getResource(resource);
    InputStream in = url.openStream();
    String pem = new String(in.readAllBytes(), StandardCharsets.ISO_8859_1);
    Pattern parse = Pattern.compile("(?m)(?s)^---*BEGIN.*---*$(.*)^---*END.*---*$.*");
    String encoded = parse.matcher(pem).replaceFirst("$1");
    return Base64.getMimeDecoder().decode(encoded);
}

@Test
public void test() throws Exception {
    KeyFactory kf = KeyFactory.getInstance("RSA");
    CertificateFactory cf = CertificateFactory.getInstance("X.509");
    PrivateKey key = kf.generatePrivate(new PKCS8EncodedKeySpec(loadPEM("test.key")));
    PublicKey pub = kf.generatePublic(new X509EncodedKeySpec(loadPEM("test.pub")));
    Certificate crt = cf.generateCertificate(getClass().getResourceAsStream("test.crt"));
}

Java 8:

replace the in.readAllBytes() call with a call to this:

byte[] readAllBytes(InputStream in) throws IOException {
    ByteArrayOutputStream baos= new ByteArrayOutputStream();
    byte[] buf = new byte[1024];
    for (int read=0; read != -1; read = in.read(buf)) { baos.write(buf, 0, read); }
    return baos.toByteArray();
}

Use the Responsive Design Tool using Ctrl + Shift + M.

Redirecting the stream is asynchronous and will potentially continue after the process has terminated. It is mentioned by Umar to cancel after process termination process.CancelOutputRead(). However that has data loss potential.

This is working reliably for me:

process.WaitForExit(...);
...
while (process.StandardOutput.EndOfStream == false)
{
    Thread.Sleep(100);
}

I didn't try this approach but I like the suggestion from Sly:

if (process.WaitForExit(timeout))
{
    process.WaitForExit();
}

Assuming that you really do want an array and not a std::vector, the "C++ way" would be this

#include <algorithm> 

int* array = new int[n]; // Assuming "n" is a pre-existing variable

std::fill_n(array, n, 0); 

But be aware that under the hood this is still actually just a loop that assigns each element to 0 (there's really not another way to do it, barring a special architecture with hardware-level support).

Download and install Eclipse, and you're good to go.
http://www.eclipse.org/downloads/

Apple provides its own version of Java, so make sure it's up-to-date.
http://developer.apple.com/java/download/

Eclipse is an integrated development environment. It has many features, but the ones that are relevant for you at this stage is:

• The source code editor
  • With syntax highlighting, colors and other visual cues
  • Easy cross-referencing to the documentation to facilitate learning
• Compiler
  • Run the code with one click
  • Get notified of errors/mistakes as you go

As you gain more experience, you'll start to appreciate the rest of its rich set of features.

You can try something like this

var access_token = driver.findElement(webdriver.By.name("AccToken"))

        var access_token_getTextFunction = function() {
            access_token.getText().then(function(value) {
                console.log(value);
                return value;
            });
        }

Than you can call this function where you want to get the value..

Edit:

Are you trying to do sth like this? See: http://twitter.github.com/bootstrap/javascript.html#tabs

See the working example: http://jsfiddle.net/U6aKT/

<a href="#id">go to id</a>
<div style="margin-top:2000px;"></div>
<a id="id">id</a>

I tried to create a byte array like this

byte[] bytes = new byte[Integer.MAX_VALUE-x];
System.out.println(bytes.length);

With this run configuration:

-Xms4G -Xmx4G

And java version:

Openjdk version "1.8.0_141"

OpenJDK Runtime Environment (build 1.8.0_141-b16)

OpenJDK 64-Bit Server VM (build 25.141-b16, mixed mode)

It only works for x >= 2 which means the maximum size of an array is Integer.MAX_VALUE-2

Values above that give

Exception in thread "main" java.lang.OutOfMemoryError: Requested array size exceeds VM limit at Main.main(Main.java:6)

its solved. Use nuget and search for the "ODP.NET, Managed Driver" invariant="Oracle.ManagedDataAccess.Client".

and install the package. it will resolve the issue for me.

You already have a lot of reading material, but if you can handle more, I recommend you learn about the evolution of python by reading the Python Enhancement Proposals, especially the "Finished" PEPs and the "Deferred, Abandoned, Withdrawn, and Rejected" PEPs.

By seeing how the language has changed, the decisions that were made and their rationales, you will absorb the philosophy of Python and understand how "idiomatic Python" comes about.

In Python it is easier to ask for forgiveness than permission. Don't sweat the nested exception handling.

(Besides, has* almost always uses exceptions under the cover anyway.)

If you are using Java 5/6, you can use Apache Commons IO for read file to string. The class org.apache.commons.io.FileUtils contais several method for read files.

e.g. using the method FileUtils#readFileToString:

File file = new File("abc.txt");
String content = FileUtils.readFileToString(file);

Temi's answer is nearly correct, but you cannot call an asynchronous function from a non asynchronous function like he is suggesting. What you need to do is make asynchronous calls in a synchronous function like so :

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider serviceProvider)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseDatabaseErrorPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();

        app.UseIdentity();

        // Add external authentication middleware below. To configure them please see https://go.microsoft.com/fwlink/?LinkID=532715

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });

        CreateRoles(serviceProvider);

    }

    private void CreateRoles(IServiceProvider serviceProvider)
    {

        var roleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
        var userManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
        Task<IdentityResult> roleResult;
        string email = "[email protected]";

        //Check that there is an Administrator role and create if not
        Task<bool> hasAdminRole = roleManager.RoleExistsAsync("Administrator");
        hasAdminRole.Wait();

        if (!hasAdminRole.Result)
        {
            roleResult = roleManager.CreateAsync(new IdentityRole("Administrator"));
            roleResult.Wait();
        }

        //Check if the admin user exists and create it if not
        //Add to the Administrator role

        Task<ApplicationUser> testUser = userManager.FindByEmailAsync(email);
        testUser.Wait();

        if (testUser.Result == null)
        {
            ApplicationUser administrator = new ApplicationUser();
            administrator.Email = email;
            administrator.UserName = email;

            Task<IdentityResult> newUser = userManager.CreateAsync(administrator, "_AStrongP@ssword!");
            newUser.Wait();

            if (newUser.Result.Succeeded)
            {
                Task<IdentityResult> newUserRole = userManager.AddToRoleAsync(administrator, "Administrator");
                newUserRole.Wait();
            }
        }

    }

The key to this is the use of the Task<> class and forcing the system to wait in a slightly different way in a synchronous way.

There is only three way to solve. paste in following code in this path application/config/autoload.php.

most of them I use this

require_once BASEPATH . '/helpers/url_helper.php';

this is good but some time, it fail

$autoload['helper'] = array('url');

I never use it but I know it work

$this->load->helper('url');

By default Laravel comes with CSRF middleware.

You have 2 options:

1. Send token in you request
2. Disable CSRF middleware (not recomended): in app\Http\Kernel.php remove VerifyCsrfToken from $middleware array

The listFiles method, with or without a filter does not guarantee any order.

It does, however, return an array, which you can sort with Arrays.sort().

File[] files = XMLDirectory.listFiles(filter_xml_files);
Arrays.sort(files);
for(File _xml_file : files) {
    ...
}

This works because File is a comparable class, which by default sorts pathnames lexicographically. If you want to sort them differently, you can define your own comparator.

If you prefer using Streams:

A more modern approach is the following. To print the names of all files in a given directory, in alphabetical order, do:

Files.list(Paths.get(dirName)).sorted().forEach(System.out::println)

Replace the System.out::println with whatever you want to do with the file names. If you want only filenames that end with "xml" just do:

Files.list(Paths.get(dirName))
    .filter(s -> s.toString().endsWith(".xml"))
    .sorted()
    .forEach(System.out::println)

Again, replace the printing with whichever processing operation you would like.

Old question but i find out how to do it faster. For my example: i have about 10k data in my table so i need some fast search machine.

Here is what i did:

$('input[name="search"]').on('keyup', function() {

        var input, filter, tr, td, i;

        input  = $(this);
        filter = input.val().toUpperCase();
        tr     = $("table tr");

        for (i = 0; i < tr.length; i++) {
            td = tr[i].getElementsByTagName("td")[0]; // <-- change number if you want other column to search
            if (td) {
                if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
                    tr[i].style.display = "";
                } else {
                    tr[i].style.display = "none";
                }
            }
        }
    })

Hope it helps somebody.

I got clear idea from this statements.

1. Async void methods have different error-handling semantics. When an exception is thrown out of an async Task or async Task method, that exception is captured and placed on the Task object. With async void methods, there is no Task object, so any exceptions thrown out of an async void method will be raised directly on the SynchronizationContext(SynchronizationContext represents a location "where" code might be executed. ) that was active when the async void method started

Exceptions from an Async Void Method Can’t Be Caught with Catch

private async void ThrowExceptionAsync()
{
  throw new InvalidOperationException();
}
public void AsyncVoidExceptions_CannotBeCaughtByCatch()
{
  try
  {
    ThrowExceptionAsync();
  }
  catch (Exception)
  {
    // The exception is never caught here!
    throw;
  }
}

These exceptions can be observed using AppDomain.UnhandledException or a similar catch-all event for GUI/ASP.NET applications, but using those events for regular exception handling is a recipe for unmaintainability(it crashes the application).

2. Async void methods have different composing semantics. Async methods returning Task or Task can be easily composed using await, Task.WhenAny, Task.WhenAll and so on. Async methods returning void don’t provide an easy way to notify the calling code that they’ve completed. It’s easy to start several async void methods, but it’s not easy to determine when they’ve finished. Async void methods will notify their SynchronizationContext when they start and finish, but a custom SynchronizationContext is a complex solution for regular application code.

3. Async Void method useful when using synchronous event handler because they raise their exceptions directly on the SynchronizationContext, which is similar to how synchronous event handlers behave

you should man date first

date +%Y-%m-%d -d yesterday

I stumbled upon this question because I created, successfully built and published a PyPI Package, but couldn't execute it after installation. The $PATHvariable was correctly set.

In my case the problem was that I hadn't set the entry_pointin the setup.py file:

entry_points = {'console_scripts':

['YOUR_CONSOLE_COMMAND=MODULE_NAME.FILE_NAME:FUNCTION_NAME'],},

Go to File > Preferences > Settings (or press Ctrl+,) then click the leftmost icon in the top right corner, "Open Settings (JSON)"

In the JSON settings window, add this (within the curly braces {}):

"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\bash.exe"`

(Here you can put any other custom settings you want as well)

Checkout that path to make sure your bash.exe file is there otherwise find out where it is and point to that path instead.

Now if you open a new terminal window in VS Code, it should open with bash instead of PowerShell.

From Python doc,

In Python 2.5, you can switch import‘s behaviour to absolute imports using a from __future__ import absolute_import directive. This absolute- import behaviour will become the default in a future version (probably Python 2.7). Once absolute imports are the default, import string will always find the standard library’s version. It’s suggested that users should begin using absolute imports as much as possible, so it’s preferable to begin writing from pkg import string in your code

for (int i=0; i<dt_pattern.Rows.Count; i++)
{
    DataRow dr = dt_pattern.Rows[i];
}

In the loop, you can now reference row i+1 (assuming there is an i+1)

Well 12 and 12.00 have exactly the same representation as double values. Are you trying to end up with a double or something else? (For example, you could cast to int, if you were convinced the value would be in the right range, and if the truncation effect is what you want.)

You might want to look at these methods too:

• Math.Floor
• Math.Ceiling
• Math.Round (with variations for how to handle midpoints)
• Math.Truncate

Notice that your error message only contains five K, V pairs, 10 arguments total. This is by design; the ImmutableMap class provides six different of() methods, accepting between zero and five key-value pairings. There is not an of(...) overload accepting a varags parameter because K and V can be different types.

You want an ImmutableMap.Builder:

ImmutableMap<String,String> myMap = ImmutableMap.<String, String>builder()
    .put("key1", "value1") 
    .put("key2", "value2") 
    .put("key3", "value3") 
    .put("key4", "value4") 
    .put("key5", "value5") 
    .put("key6", "value6") 
    .put("key7", "value7") 
    .put("key8", "value8") 
    .put("key9", "value9")
    .build();

This should work regardless of @@DATEFIRST

ALTER FUNCTION dbo.DEV_VW_WeekSerial
    (@YearNum int,
    @WeekNum int,
    @DayNum int)
    RETURNS Date AS

    BEGIN

        DECLARE @FirstDayYear As Date;

        SET @FirstDayYear='01/01/' + CAST(@YearNum As varchar)

        RETURN dateadd(d,(@DayNum-datepart(weekday,@FirstDayYear)),dateadd(week, @WeekNum-1,@FirstDayYear))

    END

The code you have is a white with low opacity.

If something white with a low opacity is above something black, you end up with a lighter shade of gray. Above red? Lighter red, etc. That is how opacity works.

Here is a simple demo.

If you want it to look 'more white', make it less opaque:

background:rgba(255,255,255, 0.9);

Demo

capitalize the first letter of Only

input[readOnly] {_x000D_
      background: red !important;_x000D_
    }

<input type="text" name="country" value="China" readonly="readonly" />

You can list down the entries (certificates details) with the keytool and even you don't need to mention the store type.

keytool -list -v -keystore cert.p12 -storepass <password>

 Keystore type: PKCS12
 Keystore provider: SunJSSE

 Your keystore contains 1 entry
 Alias name: 1
 Creation date: Jul 11, 2020
 Entry type: PrivateKeyEntry
 Certificate chain length: 2

for some reason, the ODBC user is the default username under windows even if you didn't create that user at setup time. simply typing

mysql

without specifying a username will attempt to connect with the non-existent ODBC username, and give:

Error 1045 (28000): Access denied for user 'ODBC'@'localhost' (using password: NO)

Instead, try specifying a username that you know, for example:

mysql -u root -p

where -u root specified the username root and -p will make the command prompt for a password.

For pushing a single tag: git push <reponame> <tagname>

For instance, git push production 1.0.0. Tags are not bound to branches, they are bound to commits.

When you want to have the tag's content in the master branch, do that locally on your machine. I would assume that you continued developing in your local master branch. Then just a git push origin master should suffice.

DELETE FROM table_name 
WHERE id BETWEEN 79 AND 296;

You can have any length, but of course, there can be a memory issue on the computer if the String input is too long. The output is always 32 characters.

import (
     "bufio"
     "os"
)

var (
    reader = bufio.NewReader(os.Stdin)
)

func ReadFromStdin() string{
    result, _ := reader.ReadString('\n')
    witl := result[:len(result)-1]
    return witl
}

Here is an example with function ReadFromStdin() it's like fmt.Scan(&name) but its takes all strings with blank spaces like: "Hello My Name Is ..."

var name string = ReadFromStdin()

println(name)

You don't need an onclick. Assuming you're using Bootstrap 3 Bootstrap 3 Documentation

<div class="span4 proj-div" data-toggle="modal" data-target="#GSCCModal">Clickable content, graphics, whatever</div>

If you're using Bootstrap 2, you'd follow the markup here: http://getbootstrap.com/2.3.2/javascript.html#modals

FWIW, htpasswd -n username will output the result directly to stdout, and avoid touching files altogether.

I use Visual Studio git plugin, and I have some websites running on IIS I wanted to move. A simple way that worked for me:

1. Close Visual Studio.

2. Move the code (including git folder, etc)

3. Click on the solution file from the new location

This refreshes the mapping to the new location, using the existing local git files that were moved. Once i was back in Visual Studio, my Team Explorer window showed the repos in the new location.

Demo is here: jsfiddle

Try this :

//auto-hide-placeholder-text-upon-focus
if(!$.browser.webkit){
$("input").each(
        function(){
            $(this).data('holder',$(this).attr('placeholder'));
            $(this).focusin(function(){
                $(this).attr('placeholder','');
            });
            $(this).focusout(function(){
                $(this).attr('placeholder',$(this).data('holder'));
            });

        });

}

Just Improved with Levi answer above -

Rack::Utils.parse_query URI("http://example.com?par=hello&par2=bye").query

For a string like above url, it will return

{ "par" => "hello", "par2" => "bye" } 

brief mnemonics:

git reset HEAD           :             index = HEAD
git checkout             : file_tree = index
git reset --hard HEAD    : file_tree = index = HEAD

Use the span tag with display:inline-block css attached to it. You can then use CSS and manipulate it like a div in lots of ways but if you don't include a width or height it expands and retracts based on its content.

Hope that helps.

If you dont need the whole Type variable and just want to check the type you can easily create a temp variable and use is operator.

T checkType = default(T);

if (checkType is MyClass)
{}

http://im4java.sourceforge.net/ - if you're running linux forking a new process isn't expensive.

Following code will create directories (if not exists) & then copy files.

// using System.IO;

// for ex. if you want to copy files from D:\A\ to D:\B\
foreach (var f in Directory.GetFiles(@"D:\A\", "*.*", SearchOption.AllDirectories))
{
    var fi =  new FileInfo(f);
    var di = new DirectoryInfo(fi.DirectoryName);

    // you can filter files here
    if (fi.Name.Contains("FILTER")
    {
        if (!Directory.Exists(di.FullName.Replace("A", "B"))
        {                       
            Directory.CreateDirectory(di.FullName.Replace("A", "B"));           
            File.Copy(fi.FullName, fi.FullName.Replace("A", "B"));
        }
    }
}

For img tags if you define one side then other side is resized to keep aspect ratio and by default images expand to their original size.

Using this fact if you wrap each img tag into div tag and set its width to 100% of parent div then height will be according to aspect ratio as you wanted.

http://jsfiddle.net/0o5tpbxg/

* {
    margin: 0;
    padding: 0;
}
.slider {
    display: flex;
}
.slider .slide img {
    width: 100%;
}

How about making the input a list. Then you may use standard list operations.

a=list(input("Enter the numbers"))

'default' => env('DB_CONNECTION', 'mysql'),

add this in your code

Remove the TO_DATE in the WHERE clause

TO_DATE (alarm_datetime,'DD.MM.YYYY HH24:MI:SS')

and change the code to

alarm_datetime

The error comes from to_date conversion of a date column.

Added Explanation: Oracle converts your alarm_datetime into a string using its nls depended date format. After this it calls to_date with your provided date mask. This throws the exception.

You can just add the overflow:auto option:

#second
{
   width:300px;
   height:100%;
   overflow: auto;
   background-color:#9ACD32;
}

With Java 8 you have several options, combining method references and the built-in comparing comparator:

import static java.util.Comparator.comparing;

Collection<CustomObject> list = new ArrayList<CustomObject>();

Collections.sort(list, comparing(CustomObject::getId));
//or
list.sort(comparing(CustomObject::getId));

Yes - just do it this way:

You don't need to repeat the WITH keyword

• pyenv - manages different python versions,
• all others - create virtual environment (which has isolated python version and installed "requirements"),

pipenv want combine all, in addition to previous it installs "requirements" (into the active virtual environment or create its own if none is active)

So maybe you will be happy with pipenv only.

But I use: pyenv + pyenv-virtualenvwrapper, + pipenv (pipenv for installing requirements only).

In Debian:

1. apt install libffi-dev

2. install pyenv based on https://www.tecmint.com/pyenv-install-and-manage-multiple-python-versions-in-linux/, but..

3. .. but instead of pyenv-virtualenv install pyenv-virtualenvwrapper (which can be standalone library or pyenv plugin, here the 2nd option):

   pyenv install 3.9.0

   git clone https://github.com/pyenv/pyenv-virtualenvwrapper.git $(pyenv root)/plugins/pyenv-virtualenvwrapper

   into ~/.bashrc add: export $VIRTUALENVWRAPPER_PYTHON="/usr/bin/python3"

   source ~/.bashrc

   pyenv virtualenvwrapper

Then create virtual environments for your projects (workingdir must exist):

pyenv local 3.9.0  # to prevent 'interpreter not found' in mkvirtualenv
python -m pip install --upgrade pip setuptools wheel
mkvirtualenv <venvname> -p python3.9 -a <workingdir>

and switch between projects:

workon <venvname>
python -m pip install --upgrade pip setuptools wheel pipenv

Inside a project I have the file requirements.txt, without fixing the versions inside (if some version limitation is not neccessary). You have 2 possible tools to install them into the current virtual environment: pip-tools or pipenv. Lets say you will use pipenv:

pipenv install -r requirements.txt

this will create Pipfile and Pipfile.lock files, fixed versions are in the 2nd one. If you want reinstall somewhere exactly same versions then (Pipfile.lock must be present):

pipenv install

Remember that Pipfile.lock is related to some Python version and need to be recreated if you use a different one.

As you see I write requirements.txt. This has some problems: You must remove a removed package from Pipfile too. So writing Pipfile directly is probably better.

So you can see I use pipenv very poorly. Maybe if you will use it well, it can replace everything?

EDIT 2021.01: I have changed my stack to: pyenv + pyenv-virtualenvwrapper + poetry. Ie. I use no apt or pip installation of virtualenv or virtualenvwrapper, and instead I install pyenv's plugin pyenv-virtualenvwrapper. This is easier way.

Poetry is great for me:

poetry add <package>   # install single package
poetry remove <package>
poetry install   # if you remove poetry.lock poetry will re-calculate versions

Most importantly...download https://raw.githubusercontent.com/rubygems/rubygems/master/lib/rubygems/ssl_certs/rubygems.org/AddTrustExternalCARoot-2048.pem

Figure out where to stick it

C:\>gem which rubygems
C:/Ruby21/lib/ruby/2.1.0/rubygems.rb

Then just copy the .pem file in ../2.1.0/rubygems/ssl_certs/ and go on about your business.

There are other differences. For instance, {'time': datetime.now()} cannot be serialized to JSON, but can be converted to string. You should use one of these tools depending on the purpose (i.e. will the result later be decoded).

I used the following code.

    <Label>
        <Label.Content>
            <AccessText TextWrapping="Wrap" Text="xxxxx"/>
        </Label.Content>
    </Label>

I'd advise to go for Gordon's solution as it is more performant than substr():

<?php 

$string = 'abcdef';
$repetitions = 10000000;

echo "\n\n";
echo "----------------------------------\n";
echo $repetitions . " repetitions...\n";
echo "----------------------------------\n";
echo "\n\n";

$start = microtime(true);
for($i=0; $i<$repetitions; $i++)
    $x = substr($string, -1);

echo "substr() took " . (microtime(true) - $start) . "seconds\n";

$start = microtime(true);
for($i=0; $i<$repetitions; $i++)
    $x = $string[strlen($string)-1];

echo "array access took " . (microtime(true) - $start) . "seconds\n";

die();

outputs something like

 ---------------------------------- 
 10000000 repetitions...
 ----------------------------------

 substr() took 2.0285921096802seconds 
 array access took 1.7474739551544seconds

Or you could add this to the html of the element you want to remove the border radius from (this way you wouldn't be removing it from all buttons / elements):

style="border-radius:0px; -webkit-border-radius:0px; -moz-border-radius:0px;"

The parameter(s) to isset() must be a variable reference and not an expression (in your case a concatenation); but you can group multiple conditions together like this:

if (isset($_POST['search_term'], $_POST['postcode'])) {
}

This will return true only if all arguments to isset() are set and do not contain null.

Note that isset($var) and isset($var) == true have the same effect, so the latter is somewhat redundant.

Update

The second part of your expression uses empty() like this:

empty ($_POST['search_term'] . $_POST['postcode']) == false

This is wrong for the same reasons as above. In fact, you don't need empty() here, because by that time you would have already checked whether the variables are set, so you can shortcut the complete expression like so:

isset($_POST['search_term'], $_POST['postcode']) && 
    $_POST['search_term'] && 
    $_POST['postcode']

Or using an equivalent expression:

!empty($_POST['search_term']) && !empty($_POST['postcode'])

Final thoughts

You should consider using filter functions to manage the inputs:

$data = filter_input_array(INPUT_POST, array(
    'search_term' => array(
        'filter' => FILTER_UNSAFE_RAW,
        'flags' => FILTER_NULL_ON_FAILURE,
    ),
    'postcode' => array(
        'filter' => FILTER_UNSAFE_RAW,
        'flags' => FILTER_NULL_ON_FAILURE,
    ),
));

if ($data === null || in_array(null, $data, true)) {
    // some fields are missing or their values didn't pass the filter
    die("You did something naughty");
}

// $data['search_term'] and $data['postcode'] contains the fields you want

Btw, you can customize your filters to check for various parts of the submitted values.

You can try using this open source solution that makes dealing with Excel a lot more cleaner.

http://excelwrapperdotnet.codeplex.com/

Note that HasValue will return true for an empty Guid.

bool validGuid = SomeProperty.HasValue && SomeProperty != Guid.Empty;

Add one more condition in where clause

SELECT * FROM  product 
WHERE pdate >= DATEADD(day,-30,GETDATE()) 
and   pdate <= getdate()

Or use DateDiff

SELECT * FROM  product 
WHERE DATEDIFF(day,pdate,GETDATE()) between 0 and 30 

Another idea: Compensate for your margin on the opposite side of the div.

For the side with the spacing you are looking to achieve as an example: 10px, and for the opposing side, compensate with a -10px. It works for me. This likely won't work in all scenarios, but depending on your layout and spacing of other elements, it might work great.
