For Linux, "ps aux | grep kafka" see if kafka properties are shown in the results. E.g. /path/to/kafka/server.properties

try to add this in your payload

grant_type=password&username=pippo&password=pluto

To read more than one json tip (array, attribute) I did the following.

var jVariable = JsonConvert.DeserializeObject<YourCommentaryClass>(jsonVariableContent);

change to

var jVariable = JsonConvert.DeserializeObject <List<YourCommentaryClass>>(jsonVariableContent);

Because you cannot see all the bits in the method used in the foreach loop. Example foreach loop

foreach (jsonDonanimSimple Variable in jVariable)
                {    
                    debugOutput(jVariable.Id.ToString());
                    debugOutput(jVariable.Header.ToString());
                    debugOutput(jVariable.Content.ToString());
                }

I also received an error in this loop and changed it as follows.

foreach (jsonDonanimSimple Variable in jVariable)
                    {    
                        debugOutput(Variable.Id.ToString());
                        debugOutput(Variable.Header.ToString());
                        debugOutput(Variable.Content.ToString());
                    }

I would pick "default" for data type of variable (null for strings/objects, 0 for numbers), but indeed check what code that will consume the object expects. Don't forget there there is sometimes distinction between null/default vs. "not present".

Check out null object pattern - sometimes it is better to pass some special object instead of null (i.e. [] array instead of null for arrays or "" for strings).

HttpClient is the newer of the APIs and it has the benefits of

• has a good async programming model
• being worked on by Henrik F Nielson who is basically one of the inventors of HTTP, and he designed the API so it is easy for you to follow the HTTP standard, e.g. generating standards-compliant headers
• is in the .Net framework 4.5, so it has some guaranteed level of support for the forseeable future
• also has the xcopyable/portable-framework version of the library if you want to use it on other platforms - .Net 4.0, Windows Phone etc.

If you are writing a web service which is making REST calls to other web services, you should want to be using an async programming model for all your REST calls, so that you don't hit thread starvation. You probably also want to use the newest C# compiler which has async/await support.

Note: It isn't more performant AFAIK. It's probably somewhat similarly performant if you create a fair test.

You need a mechanism which avoids busy-waiting. The old wait/notify mechanism is fraught with pitfalls so prefer something from the java.util.concurrent library, for example the CountDownLatch:

public final CountDownLatch latch = new CountDownLatch(1);

public void run () {
  latch.await();
  ...
}

And at the other side call

yourRunnableObj.latch.countDown();

However, starting a thread to do nothing but wait until it is needed is still not the best way to go. You could also employ an ExecutorService to which you submit as a task the work which must be done when the condition is met.

According to this article on sqlserverstudymaterial;

Remember that "%Privileged time" is not based on 100%.It is based on number of processors.If you see 200 for sqlserver.exe and the system has 8 CPU then CPU consumed by sqlserver.exe is 200 out of 800 (only 25%).

If "% Privileged Time" value is more than 30% then it's generally caused by faulty drivers or anti-virus software. In such situations make sure the BIOS and filter drives are up to date and then try disabling the anti-virus software temporarily to see the change.

If "% User Time" is high then there is something consuming of SQL Server. There are several known patterns which can be caused high CPU for processes running in SQL Server including

IMPORTANT NOTE

I am posting this as an answer, not a comment, as it is rather important info and it will attract more attention in this format.

As other fellows pointed, you can force a device to show you a numeric keyboard with type="number" / type="tel", but I must emphasize that you have to be extremely cautious with this.

If someone expects a number beginning with zeros, such as 000222, then she is likely to have trouble, as some browsers (desktop Chrome, for instance) will send to the server 222, which is not what she wants.

About type="tel" I can't say anything similar but personally I do not use it, as its behavior on different telephones can vary. I have confined myself to the simple pattern="[0-9]*" which do not work in Android

It sounds like you are talking about aggregation. Each instance of your player class can contain zero or more instances of Airplane, which, in turn, can contain zero or more instances of Flight. You can implement this in Python using the built-in list type to save you naming variables with numbers.

class Flight(object):

    def __init__(self, duration):
        self.duration = duration


class Airplane(object):

    def __init__(self):
        self.flights = []

    def add_flight(self, duration):
        self.flights.append(Flight(duration))


class Player(object):

    def __init__ (self, stock = 0, bank = 200000, fuel = 0, total_pax = 0):
        self.stock = stock
        self.bank = bank
        self.fuel = fuel
        self.total_pax = total_pax
        self.airplanes = []


    def add_planes(self):
        self.airplanes.append(Airplane())



if __name__ == '__main__':
    player = Player()
    player.add_planes()
    player.airplanes[0].add_flight(5)

A property that has only a getter is said to be readonly. Cause no setter is provided, to change the value of the property (from outside).

C# has has a keyword readonly, that can be used on fields (not properties). A field that is marked as "readonly", can only be set once during the construction of an object (in the constructor).

private string _name = "Foo"; // field for property Name;
private bool _enabled = false; // field for property Enabled;

public string Name{ // This is a readonly property.
  get {
    return _name;  
  }
}

public bool Enabled{ // This is a read- and writeable property.
  get{
    return _enabled;
  }
  set{
    _enabled = value;
  }
} 

You could try something like this.

def main():
    try:
        user_in = int(input("Enter a number to determine whether the number is prime or not: "))
    except ValueError:
        print()
        print("You must enter a number!")
        print()
        return
    list_range = list(range(2,user_in+1))
    divisor_list = []
    for number in list_range:
        if user_in%number==0:
            divisor_list.append(number)
    if len(divisor_list) < 2:
        print(user_in, "is a prime number!")
        return
    else:
        print(user_in, "is not a prime number!")
        return
main()

Since this question now features prominently when searching for YAML and JSON, it's worth noting one rarely-cited difference between the two: license. JSON purports to have a license which JSON users must adhere to (including the legally-ambiguous "shall be used for Good, not Evil"). YAML carries no such license claim, and that might be an important difference (to your lawyer, if not to you).

Paste my contains example here:

//table[contains(@class, "EC_result")]/tbody

No, registering an object takes a bit of memory too. 100 objects with 1 attribute will take up more memory.

'''
Only used if set your position as global
'''
position #set global 

def bst(array,taget): # just pass the array and target
        global position
        low = 0
        high = len(array)
    while low <= high:
        mid = (lo+hi)//2
        if a[mid] == target:
            position = mid
            return -1
        elif a[mid] < target: 
            high = mid+1
        else:
            low = mid-1
    return -1

I guess this is much better and effective. please correct me :) . Thank you

For Linux You can also use /proc/self/statm to get a single line of numbers containing key process memory information which is a faster thing to process than going through a long list of reported information as you get from proc/self/status

See http://man7.org/linux/man-pages/man5/proc.5.html

   /proc/[pid]/statm
          Provides information about memory usage, measured in pages.
          The columns are:

              size       (1) total program size
                         (same as VmSize in /proc/[pid]/status)
              resident   (2) resident set size
                         (same as VmRSS in /proc/[pid]/status)
              shared     (3) number of resident shared pages (i.e., backed by a file)
                         (same as RssFile+RssShmem in /proc/[pid]/status)
              text       (4) text (code)
              lib        (5) library (unused since Linux 2.6; always 0)
              data       (6) data + stack
              dt         (7) dirty pages (unused since Linux 2.6; always 0)

ADD CONSTRAINT MyConstraintName
DEFAULT 'This is not NULL' FOR names

insert into ABC(age) values(10)

select * from ABC

With multiple submits, when you need the value of the submit selected, this can be done quite easily. Just create a hidden field in your form and change its value depending on what button is clicked. For example, in the form, say you have:

<input type="hidden" id="Clicked" name="Clicked" value="" />
<button type="submit" class="btn btn-success ClickCheck" id="Create"> <i class="fa fa-file-pdf-o"> Create Bill</i></button>
<button type="submit" class="btn btn-success ClickCheck" id="Reset"> <i class="fa fa-times"> Reset</i></button>
<button type="submit" class="btn btn-success ClickCheck" id="StoreData"> <i class="fa fa-archive"> Save</i></button>

Using jQuery:

<script type="text/javascript">
    $(document).ready(function()
    {
        $('.ClickCheck').click(function()
        {
            var ButtonID = $(this).attr('id');
            $('#Clicked').val(ButtonID);
        });
    });
</script>

Then you can retrieve the value of the button clicked in the "Clicked" post variable

Consider two class-typed variables:

class Boo { ... };

Boo b0;       // mutable object
const Boo b1; // non-mutable object

Now you are able to call any member function of Boo on b0, but only const-qualified member functions on b1.

I think you just need to remove the space. i.e.

$(".myclass[reference=12345]").css('border', '#000 solid 1px');

list.add("kant");

list.add("soni");

// Iterate to disply : result will be as ---     ravi kant soni

for (String name : list) {
  ...
}

//Now call this method

Collections.reverse(list);

// iterate and print index wise : result will be as ---     soni kant ravi

for (String name : list) {
  ...
}

Depends on the consistency of the data - assuming a single space is the separator between what you want to appear in column one vs two:

SELECT SUBSTR(t.column_one, 1, INSTR(t.column_one, ' ')-1) AS col_one,
       SUBSTR(t.column_one, INSTR(t.column_one, ' ')+1) AS col_two
  FROM YOUR_TABLE t

You didn't hear it from me, the PM for Razor, but in Razor 2 (Web Pages 2 and MVC 4) we'll have conditional attributes built into Razor(as of MVC 4 RC tested successfully), so you can just say things like this...

If strCSSClass is null then the class attribute won't render at all.

I've successfully implemented ReCaptcha in the following way.
note: this is in VB, but can easily be converted

1] First grab a copy of the reCaptcha library

2] Then build a custom ReCaptcha HTML Helper

    ''# fix SO code coloring issue.
    <Extension()>
    Public Function reCaptcha(ByVal htmlHelper As HtmlHelper) As MvcHtmlString
        Dim captchaControl = New Recaptcha.RecaptchaControl With {.ID = "recaptcha",
                                                                  .Theme = "clean",
                                                                  .PublicKey = "XXXXXX",
                                                                  .PrivateKey = "XXXXXX"}
        Dim htmlWriter = New HtmlTextWriter(New IO.StringWriter)
        captchaControl.RenderControl(htmlWriter)
        Return MvcHtmlString.Create(htmlWriter.InnerWriter.ToString)
    End Function

3] From here you need a re-usable server side validator

Public Class ValidateCaptchaAttribute : Inherits ActionFilterAttribute
    Private Const CHALLENGE_FIELD_KEY As String = "recaptcha_challenge_field"
    Private Const RESPONSE_FIELD_KEY As String = "recaptcha_response_field"

    Public Overrides Sub OnActionExecuting(ByVal filterContext As ActionExecutingContext)

        If IsNothing(filterContext.HttpContext.Request.Form(CHALLENGE_FIELD_KEY)) Then
            ''# this will push the result value into a parameter in our Action
            filterContext.ActionParameters("CaptchaIsValid") = True
            Return
        End If

        Dim captchaChallengeValue = filterContext.HttpContext.Request.Form(CHALLENGE_FIELD_KEY)
        Dim captchaResponseValue = filterContext.HttpContext.Request.Form(RESPONSE_FIELD_KEY)

        Dim captchaValidtor = New RecaptchaValidator() With {.PrivateKey = "xxxxx",
                                                                       .RemoteIP = filterContext.HttpContext.Request.UserHostAddress,
                                                                       .Challenge = captchaChallengeValue,
                                                                       .Response = captchaResponseValue}

        Dim recaptchaResponse = captchaValidtor.Validate()

        ''# this will push the result value into a parameter in our Action
        filterContext.ActionParameters("CaptchaIsValid") = recaptchaResponse.IsValid

        MyBase.OnActionExecuting(filterContext)
    End Sub

above this line is reusable **ONE TIME** code

below this line is how easy it is to implement reCaptcha over and over

Now that you have your re-usable code... all you need to do is add the captcha to your View.

<%: Html.reCaptcha %>

And when you post the form to your controller...

    ''# Fix SO code coloring issues
    <ValidateCaptcha()>
    <AcceptVerbs(HttpVerbs.Post)>
    Function Add(ByVal CaptchaIsValid As Boolean, ByVal [event] As Domain.Event) As ActionResult


        If Not CaptchaIsValid Then ModelState.AddModelError("recaptcha", "*")


        '#' Validate the ModelState and submit the data.
        If ModelState.IsValid Then
            ''# Post the form
        Else
            ''# Return View([event])
        End If
    End Function

If you use Maven, you can use xvfb-maven-plugin to start xvfb before tests, run them using related DISPLAY environment variable, and stop xvfb after all.

PS: DO NOT use mail() to send those 5000 emails. In addition to what everyone else said, it is extremely inefficient since mail() creates a separate socket per email set, even to the same MTA.

Slight typo with Chris' answer.

Db.authenticate(user, password, function({ // callback }));

should be

Db.authenticate(user, password, function(){ // callback } );

Also depending on your mongodb configuration, you may need to connect to admin and auth there first before going to a different database. This will be the case if you don't add a user to the database you're trying to access. Then you can auth via admin and then switch db and then read or write at will.

Assuming that you have a data frame called students, you can select individual rows or columns using the bracket syntax, like this:

• students[1,2] would select row 1 and column 2, the result here would be a single cell.
• students[1,] would select all of row 1, students[,2] would select all of column 2.

If you'd like to select multiple rows or columns, use a list of values, like this:

• students[c(1,3,4),] would select rows 1, 3 and 4,
• students[c("stu1", "stu2"),] would select rows named stu1 and stu2.

Hope I could help.

The case-insensitive marker, (?i) can be incorporated directly into the regex pattern:

>>> import re
>>> s = 'This is one Test, another TEST, and another test.'
>>> re.findall('(?i)test', s)
['Test', 'TEST', 'test']

appearance property doesn't work in all browser. You can do like the following-

input[type="radio"]{_x000D_
  display: none;_x000D_
}_x000D_
label:before{_x000D_
  content:url(http://strawberrycambodia.com/book/admin/templates/default/images/icons/16x16/checkbox.gif);_x000D_
}_x000D_
input[type="radio"]:checked+label:before{_x000D_
  content:url(http://www.treatment-abroad.ru/img/admin/icons/16x16/checkbox.gif);_x000D_
}

 _x000D_
  <input type="radio" name="gender" id="test1" value="male">_x000D_
  <label for="test1"> check 1</label>_x000D_
  <input type="radio" name="gender" value="female" id="test2">_x000D_
  <label for="test2"> check 2</label>_x000D_
  <input type="radio" name="gender" value="other" id="test3">_x000D_
  <label for="test3"> check 3</label>  

It works IE 8+ and other browsers

For sub partitioned tables and indexes we can use the following query

    SELECT owner, table_name, ROUND(sum(bytes)/1024/1024/1024, 2) GB
    FROM
    (SELECT segment_name table_name, owner, bytes
     FROM dba_segments
     WHERE segment_type IN ('TABLE', 'TABLE PARTITION', 'TABLE SUBPARTITION')
     UNION ALL
     SELECT i.table_name, i.owner, s.bytes
     FROM dba_indexes i, dba_segments s
     WHERE s.segment_name = i.index_name
     AND   s.owner = i.owner
     AND   s.segment_type IN ('INDEX', 'INDEX PARTITION', 'INDEX SUBPARTITION')
     UNION ALL
     SELECT l.table_name, l.owner, s.bytes
     FROM dba_lobs l, dba_segments s
     WHERE s.segment_name = l.segment_name
     AND   s.owner = l.owner
     AND   s.segment_type = 'LOBSEGMENT'
     UNION ALL
     SELECT l.table_name, l.owner, s.bytes
     FROM dba_lobs l, dba_segments s
     WHERE s.segment_name = l.index_name
     AND   s.owner = l.owner
     AND   s.segment_type = 'LOBINDEX')
    WHERE owner in UPPER('&owner')
    GROUP BY table_name, owner
    HAVING SUM(bytes)/1024/1024 > 10  /* Ignore really small tables */
    ORDER BY SUM(bytes) DESC
    ;

This is a good example based on domain driven design and explains why it is important to have separate domain layer.

Use a default form value to avoid the error.

Instead of using the accepted answer of applying detectChanges() in ngAfterViewInit() (which also solved the error in my case), I decided instead to save a default value for a dynamically required form field, so that when the form is later updated, it's validity is not changed if the user decides to change an option on the form that would trigger the new required fields (and cause the submit button to be disabled).

This saved a tiny bit of code in my component, and in my case the error was avoided altogether.

In Django 1.7 this is even easier with the built-in JsonResponse.

https://docs.djangoproject.com/en/dev/ref/request-response/#jsonresponse-objects

# import it
from django.http import JsonResponse

def my_view(request):

    # do something with the your data
    data = {}

    # just return a JsonResponse
    return JsonResponse(data)

Best way to avoid OOM during Bitmap creation,

In your template

template <void (*T)(int &)>
void doOperation()

The parameter T is a non-type template parameter. This means that the behaviour of the template function changes with the value of the parameter (which must be fixed at compile time, which function pointer constants are).

If you want somthing that works with both function objects and function parameters you need a typed template. When you do this, though, you also need to provide an object instance (either function object instance or a function pointer) to the function at run time.

template <class T>
void doOperation(T t)
{
  int temp=0;
  t(temp);
  std::cout << "Result is " << temp << std::endl;
}

There are some minor performance considerations. This new version may be less efficient with function pointer arguments as the particular function pointer is only derefenced and called at run time whereas your function pointer template can be optimized (possibly the function call inlined) based on the particular function pointer used. Function objects can often be very efficiently expanded with the typed template, though as the particular operator() is completely determined by the type of the function object.

I think you can find your answer here : Is an anchor tag without the href attribute safe?

Also if you want to no link operation with href , you can use it like :

<a href="javascript:void(0);">something</a>

you have to call set and add functions on chart object before calling redraw.

chart.xAxis[0].setCategories([2,4,5,6,7], false);

chart.addSeries({
    name: "acx",
    data: [4,5,6,7,8]
}, false);

chart.redraw();

let jsonString = String(data: jsonData, encoding: .ascii)

json.dump() will preserve the ordder of your dictionary. Open the file in a text editor and you will see. It will preserve the order regardless of whether you send it an OrderedDict.

But json.load() will lose the order of the saved object unless you tell it to load into an OrderedDict(), which is done with the object_pairs_hook parameter as J.F.Sebastian instructed above.

It would otherwise lose the order because under usual operation, it loads the saved dictionary object into a regular dict and a regular dict does not preserve the oder of the items it is given.

Use this line of code in your css

border: 1px solid #000 !important;

or if you want border only in left and right side of container then use:

border-right: 1px solid #000 !important;
border-left: 1px solid #000 !important;

$("#div_element").load('script.php');

demo: http://sandbox.phpcode.eu/g/2ecbe/3

whole code:

<div id="submit">ajax</div> 
<div id="div_element"></div> 
<script> 
$('#submit').click(function(event){ 
   $("#div_element").load('script.php?html=some_arguments');  

});

You need to provide configurations considering your Spring Boot Version and the version of libraries it downloads based on the same.

My Setup: Spring Boot 1.5.x (1.5.10 in my case) downloads Hibernate v5.x

Use below only if your Spring Boot setup has downloaded Hibernate v4.

spring.jpa.hibernate.naming_strategy=org.hibernate.cfg.ImprovedNamingStrategy

Hibernate 5 doesn't support above.

If your Spring Boot Setup has downloaded Hibernate v5.x, then prefer below definition:

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

IMPORTANT: In your Spring Boot application development, you should prefer to use annotation: @SpringBootApplication which has been super-annotated with: @SpringBootConfiguration and @EnableAutoConfiguration

NOW If your entity classes are in different package than the package in which your Main Class resides, Spring Boot won't scan those packages.

Thus you need to explicitly define Annotation: @EntityScan(basePackages = { "com.springboot.entities" })
This annotation scans JPA based annotated entity classes (and others like MongoDB, Cassandra etc)

NOTE: "com.springboot.entities" is the custom package name.

Following is the way I had defined Hibernate and JPA based properties at application.properties to create Tables:-

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3333/development?useSSL=true spring.datasource.username=admin
spring.datasource.password=

spring.jpa.open-in-view=false
spring.jpa.hibernate.ddl-auto=create
spring.jpa.generate-ddl=true
spring.jpa.hibernate.use-new-id-generator-mappings=true
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.hibernate.naming.strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.format_sql=true

I am able to create tables using my above mentioned configuration.

Refer it and change your code wherever applicable.

If you are running Delphi, or other native compiled CGI, this solution will work:

1. As other pointed, go to IIS manager and click on the server name. Then click on the "ISAPI and CGI Restrictions" icon under the IIS header.

2. If you have everything allowed, it will still not work. You need to click on "Edit Feature Settings" in Actions (on the right side), and check "Allow unspecified CGI modules", or "Allow unspecified ISAPI modules" respectively.

3. Click OK

Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point

Alternatively, you could cherry-pick the commit-id onto your branch.

<commit-id> made in detached head state

git checkout master

git cherry-pick <commit-id>

No temporary branches, no merging.

This answer is for those google searchers who want to show dotted bottom border of EditText like here

Create dotted.xml inside drawable folder and paste these

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:bottom="1dp"
        android:left="-2dp"
        android:right="-2dp"
        android:top="-2dp">
        <shape android:shape="rectangle">
            <stroke
                android:width="0.5dp"
                android:color="@android:color/black" />    
            <solid android:color="#ffffff" />
            <stroke
                android:width="1dp"
                android:color="#030310"
                android:dashGap="5dp"
                android:dashWidth="5dp" />
            <padding
                android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp" />
        </shape>
    </item>
</layer-list>

Then simply set the android:background attribute to dotted.xml we just created. Your EditText looks like this.

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Some Text"
    android:background="@drawable/dotted" />

this is possible with jQuery $.ajax() method

$.ajax(serverUrl, {
   type: OutageViewModel.Id() == 0 ? "POST" : "PUT",
   data: dataToSave,
   statusCode: {
      200: function (response) {
         alert('1');
         AfterSavedAll();
      },
      201: function (response) {
         alert('1');
         AfterSavedAll();
      },
      400: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      },
      404: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      }
   }, success: function () {
      alert('1');
   },
});

Maybe the suggested solutions here worked in 2009, but ive tested all of this upvoted answers and nobody is working in any browsers.

only solution i found working is this: (but its a bit ugly to use i think)

<form method="post" name="form">
<input type="submit" value="dosomething" onclick="javascript: form.action='actionurl1';"/>
<input type="submit" value="dosomethingelse" onclick="javascript: form.action='actionurl2';"/>

Windows 10 or Windows Server 2016 provide such information in their standard task manager. A rare case for production, but if the target JVM is running on Windows, the simplest way to see its parameters is to press Ctrl+Alt+Delete, choose the Processes tab and add the Command line column (by clicking the right mouse button on any existing column header).

This is your code: http://jsfiddle.net/WSFnX/

Using display: table-cell is fine, provided that you're aware that it won't work in IE6/7. Other than that, it's safe: Is there a disadvantage of using `display:table-cell`on divs?

To fix the space at the bottom, add vertical-align: bottom to the actual imgs:

http://jsfiddle.net/WSFnX/1/

Removing the space between the images boils down to this: bikeshedding CSS3 property alternative?

So, here's a demo with the whitespace removed in your HTML: http://jsfiddle.net/WSFnX/4/

You can:

• Either, use an <input type="submit" ..>, instead of that button.
• or, Use a bit of javascript, to get a hold of form object (using name or id), and call submit(..) on it. Eg: form.submit(). Attach this code to the button click event. This will serialise the form parameters and execute a GET or POST request as specified in the form's method attribute.

scale(..) works a bit differently. You can use bufferedImage.getScaledInstance(..)

Scanf is pretty much always more trouble than it's worth. Here are two better ways to do what you're trying to do. This first one is a more-or-less direct translation of your code. It's longer, but you can look at it and see clearly what it does, unlike with scanf.

#include <stdio.h>
#include <ctype.h>
int main(void)
{
    char buf[1024], *p, *q;
    while (fgets(buf, 1024, stdin))
    {
        p = buf;
        while (*p)
        {
            while (*p && isspace(*p)) p++;
            q = p;
            while (*q && !isspace(*q)) q++;
            *q = '\0';
            if (p != q)
                puts(p);
            p = q;
        }
    }
    return 0;
}

And here's another version. It's a little harder to see what this does by inspection, but it does not break if a line is longer than 1024 characters, so it's the code I would use in production. (Well, really what I would use in production is tr -s '[:space:]' '\n', but this is how you implement something like that.)

#include <stdio.h>
#include <ctype.h>
int main(void)
{
    int ch, lastch = '\0';
    while ((ch = getchar()) != EOF)
    {
        if (!isspace(ch))
            putchar(ch);
        if (!isspace(lastch))
            putchar('\n');
        lastch = ch;
    }
    if (lastch != '\0' && !isspace(lastch))
        putchar('\n');
    return 0;
}

In tandem with what Pedro Fontez said a few replies up, you seemed to never call the sys module initially, nor did you manage to stick the required () at the end of sys.exit:

so:

import sys

and when finished:

sys.exit()

This solution is working:

• Enter the computer in the Active Directory domain with authentication (no Restart)
• Rename the computer with authentication (no Restart)
• after, Restart

In code:

# get the credential 
$cred = get-credential

# enter the computer in the right place
Add-Computer -DomainName EPFL -Credential $cred -OUPath "...,DC=epfl,DC=ch"

# rename the computer with credential (because we are in the domain)
$Computer = Get-WmiObject Win32_ComputerSystem
$r = $Computer.Rename("NewComputerName", $cred.GetNetworkCredential().Password, $cred.Username)

Inside your project folder their is a bin folder. Inside your bin folder, there are 2 folders, a Release and a Debug. For your polished .exe, you want to go into your Release folder.

I'm not quite sure if thats what youre asking

As of 2015, the most convenient way according to me to sort Date column in a DataTable, is using the required sort plugin. Since the date format in my case was dd/mm/yyyy hh:mm:ss, I ended up using the date-euro plugin. All one needs to do is:

Step 1: Include the sorting plugin JavaScript file or code and;

Step 2: Add columnDefs as shown below to target appropriate column(s).

$('#example').dataTable( {
    columnDefs: [
       { type: 'date-euro', targets: 0 }
    ]
});

If you want to plot lines instead of points, see this example, modified here to plot good/bad points representing a function as a black/red as appropriate:

def plot(xx, yy, good):
    """Plot data

    Good parts are plotted as black, bad parts as red.

    Parameters
    ----------
    xx, yy : 1D arrays
        Data to plot.
    good : `numpy.ndarray`, boolean
        Boolean array indicating if point is good.
    """
    import numpy as np
    import matplotlib.pyplot as plt
    fig, ax = plt.subplots()
    from matplotlib.colors import from_levels_and_colors
    from matplotlib.collections import LineCollection
    cmap, norm = from_levels_and_colors([0.0, 0.5, 1.5], ['red', 'black'])
    points = np.array([xx, yy]).T.reshape(-1, 1, 2)
    segments = np.concatenate([points[:-1], points[1:]], axis=1)
    lines = LineCollection(segments, cmap=cmap, norm=norm)
    lines.set_array(good.astype(int))
    ax.add_collection(lines)
    plt.show()

When we do this:

def foo(a=[]):
    ...

... we assign the argument a to an unnamed list, if the caller does not pass the value of a.

To make things simpler for this discussion, let's temporarily give the unnamed list a name. How about pavlo ?

def foo(a=pavlo):
   ...

At any time, if the caller doesn't tell us what a is, we reuse pavlo.

If pavlo is mutable (modifiable), and foo ends up modifying it, an effect we notice the next time foo is called without specifying a.

So this is what you see (Remember, pavlo is initialized to []):

 >>> foo()
 [5]

Now, pavlo is [5].

Calling foo() again modifies pavlo again:

>>> foo()
[5, 5]

Specifying a when calling foo() ensures pavlo is not touched.

>>> ivan = [1, 2, 3, 4]
>>> foo(a=ivan)
[1, 2, 3, 4, 5]
>>> ivan
[1, 2, 3, 4, 5]

So, pavlo is still [5, 5].

>>> foo()
[5, 5, 5]

I like Alfonso Tienda responce from HTTP status code for update and delete?

Here are some Tips:

DELETE

• 200 (if you want send some additional data in the Response) or 204 (recommended).

• 202 Operation deleted has not been committed yet.

• If there's nothing to delete, use 204 or 404 (DELETE operation is idempotent, delete an already deleted item is operation successful, so you can return 204, but it's true that idempotent doesn't necessarily imply the same response)

Other errors:

• 400 Bad Request (Malformed syntax or a bad query is strange but possible).
• 401 Unauthorized Authentication failure
• 403 Forbidden: Authorization failure or invalid Application ID.
• 405 Not Allowed. Sure.
• 409 Resource Conflict can be possible in complex systems.
• And 501, 502 in case of errors.

PUT

If you're updating an element of a collection

• 200/204 with the same reasons as DELETE above.
• 202 if the operation has not been commited yet.

The referenced element doesn't exists:

• PUT can be 201 (if you created the element because that is your behaviour)

• 404 If you don't want to create elements via PUT.

• 400 Bad Request (Malformed syntax or a bad query more common than in case of DELETE).

• 401 Unauthorized

• 403 Forbidden: Authentication failure or invalid Application ID.

• 405 Not Allowed. Sure.

• 409 Resource Conflict can be possible in complex systems, as in DELETE.

• 422 Unprocessable entity It helps to distinguish between a "Bad request" (e.g. malformed XML/JSON) and invalid field values

• And 501, 502 in case of errors.

Building on @Adrien Be's answer above and using the code that Brian Huisman & David koelle created, here is a modified prototype sorting for an array of objects:

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

Answer for the "new" and "cool" Microsoft.

Yay, SQL Server driver now under MIT license on

• GitHub: https://github.com/Microsoft/mssql-jdbc
• Maven Central: http://search.maven.org/#search%7Cga%7C1%7Cmssql-jdbc

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>6.1.0.jre8</version>
</dependency>

Answer for the "old" Microsoft:

For my use-case (integration testing) it was sufficient to use a system scope for the JDBC driver's dependency as such:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>3.0</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/sqljdbc4.jar</systemPath>
    <optional>true</optional>
</dependency>

That way, I could put the JDBC driver into local version control. No need to have each developer manually set stuff up in their own repositories.

I took inspiration from this answer to another Stack Overflow question and I've also blogged about it here.

Related answer, you can specify the number of playbacks on a gif. The below gif has 3 playbacks associated with it (10 second timer, 30 second playback total). After 30 seconds have passed since page load, it stops at "0:01".

Refresh the page to restart all 3 playbacks

You have to modify the gif itself. An easy tool is found here for modifying GIF playbacks https://ezgif.com/loop-count.

To see an example of a single-loop playback gif in action on a landing page, checkout this site using a single playback gif https://git-lfs.github.com/

So gaiour is right, but if you're looking for a full height item that doesn't scroll with the content, but is actually the height of the container, here's the fix. Have a parent with a height that causes overflow, a content container that has a 100% height and overflow: scroll, and a sibling then can be positioned according to the parent size, not the scroll element size. Here is the fiddle: http://jsfiddle.net/M5cTN/196/

and the relevant code:

html:

<div class="container">
  <div class="inner">
    Lorem ipsum ...
  </div>
  <div class="full-height"></div>
</div>

css:

.container{
  height: 256px;
  position: relative;
}
.inner{
  height: 100%;
  overflow: scroll;
}
.full-height{
  position: absolute;
  left: 0;
  width: 20%;
  top: 0;
  height: 100%;
}

Quite logical the difference between PUT & PATCH w.r.t sending full & partial data for replacing/updating respectively. However, just couple of points as below

1. Sometimes POST is considered as for updates w.r.t PUT for create
2. Does HTTP mandates/checks for sending full vs partial data in PATCH? Otherwise, PATCH may be quite same as update as in PUT/POST

The html

<select id="drop"  name="company" class="company btn btn-outline   dropdown-toggle" >
   <option value="demo1">Group Medical</option>
   <option value="demo">Motor Insurance</option>
</select>

Script.js

$("#drop").change(function () {                            
   var category= $('select[name=company]').val() // Here we can get the value of selected item
   alert(category); 
});

Use tqdm_notebook

from tqdm import tqdm_notebook as tqdm

x=[1,2,3,4,5]

for i in tqdm(range(0,len(x))):

    print(x[i])

 git reset --soft commit_id
 git stash save "message"
 git reset --hard commit_id
 git stash apply stash stash@{0}
 git push --force

I think, this is you exactly needed.

Here drawable(xml) file that creates rounded rectangle. round_rect_shape.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"

        android:bottomRightRadius="8dp"
        android:topLeftRadius="8dp"
        android:topRightRadius="8dp" />

</shape>

Here layout file: my_layout.xml

<LinearLayout

    </EditText>
</LinearLayout>

-> In the above code, LinearLayout having the background(That is the key role to place to create rounded rectangle). So you can place any view like TextView, EditText... in that LinearLayout to see background as round rectangle for all.

Workaround with links:

ln path/to/file/outside/context/file_to_copy ./file_to_copy

On Dockerfile, simply:

COPY file_to_copy /path/to/file

git checkout .

i always use this command to replace my local changes with repository changes. git checkout space dot.

try:

$("td[id^=" + value + "]")

I think nt86's solution is the most appropriate because it leverages the underlying Windows infrastructure (certificate store). But it doesn't explain how to install python-certifi-win32 to start with since pip is non functional.

The trick is to use --trustedhost to install python-certifi-win32 and then after that, pip will automatically use the windows certificate store to load the certificate used by the proxy.

So in a nutshell, you should do:

pip install python-certifi-win32 -trustedhost pypi.org

and after that you should be good to go

// wrap it in jQuery, now it's a collection
var $elements = $(someHTML);

// append to the DOM
$("#myDiv").append($elements);

// do stuff, using the initial reference
$elements.effects("highlight", {}, 2000);

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

Overall

SELECT
       COUNT(DISTINCT `site_id`) as distinct_sites
  FROM `cp_visits`
 WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)

Or per site

  SELECT
         `site_id` as site,
         COUNT(DISTINCT `user_id`) as distinct_users_per_site
    FROM `cp_visits`
   WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
GROUP BY `site_id`

Having the time column in the result doesn't make sense - since you are aggregating the rows, showing one particular time is irrelevant, unless it is the min or max you are after.

Undefined reference to vtable may occur due to the following situation also. Just try this:

Class A Contains:

virtual void functionA(parameters)=0; 
virtual void functionB(parameters);

Class B Contains:

1. The definition for the above functionA.
2. The definition for the above functionB.

Class C Contains: Now you're writing a Class C in which you are going to derive it from Class A.

Now if you try to compile you will get Undefined reference to vtable for Class C as error.

Reason:

functionA is defined as pure virtual and its definition is provided in Class B. functionB is defined as virtual (NOT PURE VIRTUAL) so it tries to find its definition in Class A itself but you provided its definition in Class B.

Solution:

1. Make function B as pure virtual (if you have requirement like that) virtual void functionB(parameters) =0; (This works it is Tested)
2. Provide Definition for functionB in Class A itself keeping it as virtual . (Hope it works as I didn't try this)

create shake.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromXDelta="0" 
        android:toXDelta="10" 
            android:duration="1000" 
                android:interpolator="@anim/cycle" />

and cycle.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
    android:cycles="4" />

now add animation on your code

Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
anyview.startAnimation(shake);

If you want vertical animation, change fromXdelta and toXdelta value to fromYdelta and toYdelta value

Looked around a bit, and the only thing I find is using the open system call. It is the only function I found that allows you to create a file in a way that will fail if it already exists

#include <fcntl.h>
#include <errno.h>

int fd=open(filename, O_WRONLY | O_CREAT | O_EXCL, S_IRUSR | S_IWUSR);
if (fd < 0) {
  /* file exists or otherwise uncreatable
     you might want to check errno*/
}else {
  /* File is open to writing */
}

Note that you have to give permissions since you are creating a file.

This also removes any race conditions there might be

I had a similar issue but in my case, the solution was to dispatch the action as an async task in the main queue

DispatchQueue.main.async {
    let vc = self.storyboard?.instantiateViewController(withIdentifier: myVCID) as! myVCName
    self.present(vc, animated: true, completion: nil)
}

There is the same border effect in Firefox and Internet Explorer (IE), it becomes visible when you click on some link.

This code will fix just IE:

a:active { outline: none; }.

And this one will fix both Firefox and IE:

:active, :focus { outline: none; -moz-outline-style: none; }

Last code should be added into your stylesheet, if you would like to remove the link borders from your site.

Use Heredocs to output muli-line strings containing variables. The syntax is...

$string = <<<HEREDOC
   string stuff here
HEREDOC;

The "HEREDOC" part is like the quotes, and can be anything you want. The end tag must be the only thing on it's line i.e. no whitespace before or after, and must end in a colon. For more info check out the manual.

Yes, this form of initialization is supported by all C++ compilers. It is a part of C++ language. In fact, it is an idiom that came to C++ from C language. In C language = { 0 } is an idiomatic universal zero-initializer. This is also almost the case in C++.

Since this initalizer is universal, for bool array you don't really need a different "syntax". 0 works as an initializer for bool type as well, so

bool myBoolArray[ARRAY_SIZE] = { 0 };

is guaranteed to initialize the entire array with false. As well as

char* myPtrArray[ARRAY_SIZE] = { 0 };

in guaranteed to initialize the whole array with null-pointers of type char *.

If you believe it improves readability, you can certainly use

bool myBoolArray[ARRAY_SIZE] = { false };
char* myPtrArray[ARRAY_SIZE] = { nullptr };

but the point is that = { 0 } variant gives you exactly the same result.

However, in C++ = { 0 } might not work for all types, like enum types, for example, which cannot be initialized with integral 0. But C++ supports the shorter form

T myArray[ARRAY_SIZE] = {};

i.e. just an empty pair of {}. This will default-initialize an array of any type (assuming the elements allow default initialization), which means that for basic (scalar) types the entire array will be properly zero-initialized.

For me, other answers didn't work. I had to go to open Files and do Invalidate caches and restart on Intellij. After that, everything worked fine again.

kubectl rollout restart deployment myapp

This is the current way to trigger a rolling update and leave the old replica sets in place for other operations provided by kubectl rollout like rollbacks.

You might consider using a shell without history, like perhaps

/bin/sh << END
   your commands without history
END

(perhaps /bin/dash or /bin/sash could be more appropriate than /bin/sh)

or even better use the batch utility e.g

batch << EOB
   your commands
EOB

The history would then contain sh or batch which is not very meaningful

For php 7.1

sudo apt-get install php7.1-mbstring

Cheers!

Even in base Python you can do the computation in generic form

result = sum(x**2 for x in some_vector) ** 0.5

x ** 2 is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).

Using instead x ** 0.5 to take the square root doesn't do the exact same computations as math.sqrt as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.

I often use x ** 0.5 simply because I don't want to add math just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.

If your numbers are always 4 digits long:

=RIGHT(A1,LEN(A1)-5) //'0001 Baseball' returns Baseball

If the numbers are variable (i.e. could be more or less than 4 digits) then:

=RIGHT(A1,LEN(A1)-FIND(" ",A1,1)) //'123456 Baseball’ returns Baseball

Try to remove % chars as below

UPDATE dbo.xxx
SET Value = REPLACE(Value, '123', '')
WHERE ID <=4

- SwiftUI

In SwiftUI, you can use cornerRadius modifier directly on any View you want. For example of this question:

Text("Signing In…")
    .padding(16)
    .background(Color.red)
    .cornerRadius(50)

Note that there is no more diamond like radius, so even if you set the cornerRadius more than half of the height, it will round smoothly.

Checkout this answer to se how to Round Specific Corners in SwiftUI

You can use the shell for this purpose.

Set shl = CreateObject("WScript.Shell") 
shl.Run "cmd mkdir YourDir" & copy "

I don't fully understand what you really mean by initializing an array?

Here's an example:

class Environment {

    // you can declare private, public and protected variables in constructor signature 
    constructor(
        private id: string,
        private name: string
    ) { 
        alert( this.id );
    }
}


let environments = new Environment('a','b');

// creating and initializing array of Environment objects
let envArr: Array<Environment> = [ 
        new Environment('c','v'), 
        new Environment('c','v'), 
        new Environment('g','g'), 
        new Environment('3','e') 
  ];

Try it here : https://www.typescriptlang.org/play/index.html

If you need to set the mirror in a non-interactive way (for example doing an rbundler install in a deploy script) you can do it in this way:

First manually run:

chooseCRANmirror()

Pick the mirror number that is best for you and remember it. Then to automate the selection:

R -e 'chooseCRANmirror(graphics=FALSE, ind=87);library(rbundler);bundle()'

Where 87 is the number of the mirror you would like to use. This snippet also installs the rbundle for you. You can omit that if you like.

This will tell you not only that it exists but also how many times it appears:

 a = ['Cat', 'Dog', 'Bird']
 a.count("Dog")
 #=> 1

The problem lies on your proxy. Because the location provider of your install package creates its own certificate and does not buy a verified one from an accepted authority, your proxy does not allow access to the targeted host. I assume that you bypass the proxy when using the Chrome Browser. So there is no checking.

There are some solutions to this problem. But all imply that you trust the package provider.

Possible solutions:

1. As mentioned in other answers you can make an http:// access which may bypass your proxy. That's a bit dangerous, because the man in the middle can inject malware into you downloads.
2. The wget suggests you to use a flag --no-check-certificate. This will add a proxy directive to your request. The proxy, if it understands the directive, does not check if the servers certificate is verified by an authority and passes the request. Perhaps there is a config with npm that does the same as the wget flag.
3. You configure your proxy to accept CA npm. I don't know your proxy, so I can't give you a hint.

solving this problem I have simply copied the tools.jar file from C:\Program Files\Java\jre1.8.0_112\lib to C:\Program Files\Java\jdk1.8.0_112\lib so that I have two tools.jar files instead of one and problem disappeared.

Run Visual Studio as Administrator, it worked for me

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

Inspired by this answer, this solution works in my case(I needed to check whether the value recieved from API is a date or not):

!isNaN(Date.parse(new Date(YourVariable)))

This way, if it is some random string coming from a client, or any other object, you can find out if it is a Date-like object.

Using extract-css-chunks-webpack-plugin and css-loader loader work for me, see below:

webpack.config.js Import extract-css-chunks-webpack-plugin

const ExtractCssChunks = require('extract-css-chunks-webpack-plugin');

webpack.config.js Add the css rule, Extract css Chunks first then the css loader css-loader will embed them into the html document, ensure css-loader and extract-css-chunks-webpack-plugin are in the package.json dev dependencies

rules: [
      {
        test: /\.css$/,
        use: [
          {
            loader: ExtractCssChunks.loader,
          },
          'css-loader',
        ],
      }
]

webpack.config.js Make instance of the plugin

plugins: [
    new ExtractCssChunks({
      // Options similar to the same options in webpackOptions.output
      // both options are optional
      filename: '[name].css',
      chunkFilename: '[id].css'
    })
  ]

And now importing css is possible And now in a tsx file like index.tsx i can use import like this import './Tree.css' where Tree.css contains css rules like

body {
    background: red;
}

My app is using typescript and this works for me, check my repo for the source : https://github.com/nickjohngray/staticbackeditor

For me, the cause was I opened the same file in both the Primary Editor and Assistant Editor at the same time. Once I closed Assistant Editor, it came through. (Xcode Version 7.2.1)

This is how use SignarR in order to target a specific user (without using any provider):

 private static ConcurrentDictionary<string, string> clients = new ConcurrentDictionary<string, string>();

 public string Login(string username)
 {
     clients.TryAdd(Context.ConnectionId, username);            
     return username;
 }

// The variable 'contextIdClient' is equal to Context.ConnectionId of the user, 
// once logged in. You have to store that 'id' inside a dictionaty for example.  
Clients.Client(contextIdClient).send("Hello!");

The Z stands for 'Zulu' - your times are in UTC. From Wikipedia:

The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history). Since the NATO phonetic alphabet and amateur radio word for Z is "Zulu", UTC is sometimes known as Zulu time. This is especially true in aviation, where Zulu is the universal standard.

The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization header with the Bearer authentication scheme.

This scheme is described by the RFC6750.

Example:

GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer eyJhbGciOiJIUzI1NiIXVCJ9TJV...r7E20RMHrHDcEfxjoYZgeFONFh7HgQ

If you need stronger security protection, you may also consider the following IETF draft: https://tools.ietf.org/html/draft-ietf-oauth-pop-architecture. This draft seems to be a good alternative to the (abandoned?) https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac.

Note that even if this RFC and the above specifications are related to the OAuth2 Framework protocol, they can be used in any other contexts that require a token exchange between a client and a server.

Unlike the custom JWT scheme you mention in your question, the Bearer one is registered at the IANA.

Concerning the Basic and Digest authentication schemes, they are dedicated to authentication using a username and a secret (see RFC7616 and RFC7617) so not applicable in that context.

Don't try to use grep for this, use awk instead. To match 2 regexps R1 and R2 in grep you'd think it would be:

grep 'R1.*R2|R2.*R1'

while in awk it'd be:

awk '/R1/ && /R2/'

but what if R2 overlaps with or is a subset of R1? That grep command simply would not work while the awk command would. Lets say you want to find lines that contain the and heat:

$ echo 'theatre' | grep 'the.*heat|heat.*the'
$ echo 'theatre' | awk '/the/ && /heat/'
theatre

You'd have to use 2 greps and a pipe for that:

$ echo 'theatre' | grep 'the' | grep 'heat'
theatre

and of course if you had actually required them to be separate you can always write in awk the same regexp as you used in grep and there are alternative awk solutions that don't involve repeating the regexps in every possible sequence.

Putting that aside, what if you wanted to extend your solution to match 3 regexps R1, R2, and R3. In grep that'd be one of these poor choices:

grep 'R1.*R2.*R3|R1.*R3.*R2|R2.*R1.*R3|R2.*R3.*R1|R3.*R1.*R2|R3.*R2.*R1' file
grep R1 file | grep R2 | grep R3

while in awk it'd be the concise, obvious, simple, efficient:

awk '/R1/ && /R2/ && /R3/'

Now, what if you actually wanted to match literal strings S1 and S2 instead of regexps R1 and R2? You simply can't do that in one call to grep, you have to either write code to escape all RE metachars before calling grep:

S1=$(sed 's/[^^]/[&]/g; s/\^/\\^/g' <<< 'R1')
S2=$(sed 's/[^^]/[&]/g; s/\^/\\^/g' <<< 'R2')
grep 'S1.*S2|S2.*S1'

or again use 2 greps and a pipe:

grep -F 'S1' file | grep -F 'S2'

which again are poor choices whereas with awk you simply use a string operator instead of regexp operator:

awk 'index($0,S1) && index($0.S2)'

Now, what if you wanted to match 2 regexps in a paragraph rather than a line? Can't be done in grep, trivial in awk:

awk -v RS='' '/R1/ && /R2/'

How about across a whole file? Again can't be done in grep and trivial in awk (this time I'm using GNU awk for multi-char RS for conciseness but it's not much more code in any awk or you can pick a control-char you know won't be in the input for the RS to do the same):

awk -v RS='^$' '/R1/ && /R2/'

So - if you want to find multiple regexps or strings in a line or paragraph or file then don't use grep, use awk.

Just for future reference, if you already have a boolean column and you just want to add a default do:

ALTER TABLE users
  ALTER COLUMN priv_user SET DEFAULT false;

It's not good for several reasons:

• it mixes code and markup
• code written this way goes through eval
• and runs in the global scope

The simplest thing would be to add a name attribute to your <a> element, then you could do:

document.myelement.onclick = function() {
    window.popup('/map/', 300, 300, 'map');
    return false;
};

although modern best practise would be to use an id instead of a name, and use addEventListener() instead of using onclick since that allows you to bind multiple functions to a single event.

Well, they don't do the same thing, really.

$_SERVER['REQUEST_METHOD'] contains the request method (surprise).

$_POST contains any post data.

It's possible for a POST request to contain no POST data.

I check the request method — I actually never thought about testing the $_POST array. I check the required post fields, though. So an empty post request would give the user a lot of error messages - which makes sense to me.

In Java, the single operators &, |, ^, ! depend on the operands. If both operands are ints, then a bitwise operation is performed. If both are booleans, a "logical" operation is performed.

If both operands mismatch, a compile time error is thrown.

The double operators &&, || behave similarly to their single counterparts, but both operands must be conditional expressions, for example:

if (( a < 0 ) && ( b < 0 )) { ... } or similarly, if (( a < 0 ) || ( b < 0 )) { ... }

Others are correct in saying that setting button.enabled = false doesn't prevent the button from triggering. However, I found that setting button.visible = false does work. The button disappears and can't be clicked until you set visible to true again.

If your test and webapp are in the same Maven project, you can use a property in the project POM. Then you can filter certain files which will allow Maven to set the property in those files. There are different ways to filter, but the most common is during the resources phase - http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-description.html

If the test and webapp are in different Maven projects, you can put the property in settings.xml, which is in your maven repository folder (C:\Documents and Settings\username.m2) on Windows. You will still need to use filtering or some other method to read the property into your test and webapp.

solution :

 public Response Get(string jsonData) {
     var json = JsonConvert.DeserializeObject<modelname>(jsonData);
     var data = StoredProcedure.procedureName(json.Parameter, json.Parameter, json.Parameter, json.Parameter);
     return data;
 }

model:

 public class modelname {
     public long parameter{ get; set; }
     public int parameter{ get; set; }
     public int parameter{ get; set; }
     public string parameter{ get; set; }
 }

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

Short trick: after I only REMOVED SPACES from names of the folders, where the .jar file was, double-clicked worked and the file executed.

I still believe its to do with the props file not being located by spring. Do a quick test by passing the params as jvm params. i.e -Didm.url=....

I got this error when Updating code first MVC5 database. Dropping (right click, delete) all the tables from my database and removing the migrations from the Migration folder worked for me.

I'm going to agree with shodanex, it looks like you're prematurely trying to optimize something that isn't yet problematic. Unless you know sockets are going to be a bottleneck, I'd just use them.

A lot of people who swear by named pipes find a little savings (depending on how well everything else is written), but end up with code that spends more time blocking for an IPC reply than it does doing useful work. Sure, non-blocking schemes help this, but those can be tricky. Spending years bringing old code into the modern age, I can say, the speedup is almost nil in the majority of cases I've seen.

If you really think that sockets are going to slow you down, then go out of the gate using shared memory with careful attention to how you use locks. Again, in all actuality, you might find a small speedup, but notice that you're wasting a portion of it waiting on mutual exclusion locks. I'm not going to advocate a trip to futex hell (well, not quite hell anymore in 2015, depending upon your experience).

Pound for pound, sockets are (almost) always the best way to go for user space IPC under a monolithic kernel .. and (usually) the easiest to debug and maintain.

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

tar -zxf tmp.tar.gz -C ~/tmp1

Did you verify that the control causing the post back has CausesValidation set to tru and that it does not have a validation group assigned to it?

I'm not sure what else might cause this behavior.

With jscript:

@if (@X)==(@Y) @end /*

    @exit /b %errorlevel%
*/if(WScript.Arguments.Count()>0) WScript.StdOut.Write(WScript.Arguments.Item(0));

if it is called write.bat you can test it like:

call write.bat string & echo _Another_String_

If you want to use powershell but with cmd defined variables you can use:

set str=_My_StrinG_
powershell "Write-Host -NoNewline ""%str%""""  & echo #Another#STRING#

If you're using Swift 2 and you want to check the OS version to use a certain API, you can use new availability feature:

if #available(iOS 8, *) {
    //iOS 8+ code here.
}
else {
    //Code for iOS 7 and older versions.
    //An important note: if you use #availability, Xcode will also 
    //check that you don't use anything that was introduced in iOS 8+
    //inside this `else` block. So, if you try to use UIAlertController
    //here, for instance, it won't compile. And it's great.
}

The first is easiest(involves less typing), and it is guaranteed to work, all members will be set to 0^{[Ref 1]}.
The second is more readable.

The choice depends on user preference or the one which your coding standard mandates.

^{[Ref 1]} Reference C99 Standard 6.7.8.21:

If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

Here is the simplest way I could find by extending TextView

public class CustomTextView extends androidx.appcompat.widget.AppCompatTextView {

float mStroke;

public CustomTextView(Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);
    TypedArray a = context.obtainStyledAttributes(attrs,
            R.styleable.CustomTextView);
    mStroke=a.getFloat(R.styleable.CustomTextView_stroke,1.0f);
    a.recycle();
}

@Override
protected void onDraw(Canvas canvas) {
    TextPaint paint = this.getPaint();
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth(mStroke);
    
    super.onDraw(canvas);
}
}

then you only need to add the following to the attrs.xml file

<declare-styleable name="CustomTextView">
    <attr name="stroke" format="float"/>
</declare-styleable>

and now you will be able to set the stroke widht by app:stroke while retaining all other desirable properties of TextView. my solution only draws the stroke w/o a fill. this makes it a bit simpler than the others. bellow a screencapture with the result while setting a custom font to my customtextview.

Feel free to use my form sheet controller MZFormSheetControllerfor iPhone, in example project there are many examples on how to present modal view controller which will not cover full window and has many presentation/transition styles.

You can also try newest version of MZFormSheetController which is called MZFormSheetPresentationController and have a lot of more features.

From the docs:

_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.

So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.

Edit: Further reading led me here:

http://www.analyticsmarket.com/blog/edit-ecommerce-data

Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

My requirement was to import the .csv (with no headline) to remote MongoDB instance. For mongoimport v3.0.7below command worked for me:

mongoimport -h <host>:<port> -u <db-user> -p <db-password>  -d <database-name> -c <collection-name> --file <csv file location> --fields <name of the columns(comma seperated) in csv> --type csv

For example:

mongoimport -h 1234.mlab.com:61486 -u arpitaggarwal -p password  -d my-database -c employees --file employees.csv --fields name,email --type csv

Below is the screenshot of how it looks like after import:

where name and email are the columns in the .csv file.

If the structures are of compatible types, yes, you can, with something like:

memcpy (dest_struct, source_struct, sizeof (*dest_struct));

The only thing you need to be aware of is that this is a shallow copy. In other words, if you have a char * pointing to a specific string, both structures will point to the same string.

And changing the contents of one of those string fields (the data that the char * points to, not the char * itself) will change the other as well.

If you want a easy copy without having to manually do each field but with the added bonus of non-shallow string copies, use strdup:

memcpy (dest_struct, source_struct, sizeof (*dest_struct));
dest_struct->strptr = strdup (source_struct->strptr);

This will copy the entire contents of the structure, then deep-copy the string, effectively giving a separate string to each structure.

And, if your C implementation doesn't have a strdup (it's not part of the ISO standard), get one from here.

Why don't you just use .to_frame if both have the same indexes?

>= v0.23

a.to_frame().join(b)

< v0.23

a.to_frame().join(b.to_frame())

Of course. The whole idea of abstract classes is that they can contain some behaviour or data which you require all sub-classes to contain. Think of the simple example of WheeledVehicle - it should have a numWheels member variable. You want all sub classes to have this variable. Remember that abstract classes are a very useful feature when developing APIs, as they can ensure that people who extend your API won't break it.

Mostly we write below statement select * from table where length(ltrim(rtrim(field)))=10;

Near the top of the file, you need to write var fadeDiv = ... instead of fadeDiv = ... so that the variable is actually declared.

The error "Property 'fadeDiv' does not exist on type '{}'." seems to be triggering on a line you haven't posted in your example (there is no access of a fadeDiv property anywhere in that snippet).

The only way to do this is via various CSS hacks, which will make your page much more likely to fail on the next browser updates. If anything, it will be LESS safe than using a js-browser sniffer.

I tried this -

1. list files which we want to ignore

git status .idea/xyz.xml .idea/pqr.iml Output .DS_Store

2. Copy the content of step#1 and append it into .gitignore file.

echo " .idea/xyz.xml .idea/pqr.iml Output .DS_Store" >> .gitignore

3. Validate

git status .gitignore

likewise we can add directory and all of its sub dir/files which we want to ignore in git status using directoryname/* and I executed this command from src directory.

First, remove all files from your Git repository using: git rm -r *

After that you should commit: using git commit -m "your comment"

After that you push using: git push (that's update the origin repository)

To verify your status using: git status

After that you can copy all your local files in the local Git folder, and you add them to the Git repository using: git add -A

You commit (git commit -m "your comment" and you push (git push)

the following code is for making the same y axis limit on two subplots

f ,ax = plt.subplots(1,2,figsize = (30, 13),gridspec_kw={'width_ratios': [5, 1]})
df.plot(ax = ax[0], linewidth = 2.5)
ylim = [lower_limit,upper_limit]
ax[0].set_ylim(ylim)
ax[1].hist(data,normed =1, bins = num_bin, color = 'yellow' ,alpha = 1) 
ax[1].set_ylim(ylim)

just a reminder, plt.hist(range=[low, high]) the histogram auto crops the range if the specified range is larger than the max&min of the data points. So if you want to specify the y-axis range number, i prefer to use set_ylim

OAuth 2.0 defines a protocol, i.e. specifies how tokens are transferred, JWT defines a token format.

OAuth 2.0 and "JWT authentication" have similar appearance when it comes to the (2nd) stage where the Client presents the token to the Resource Server: the token is passed in a header.

But "JWT authentication" is not a standard and does not specify how the Client obtains the token in the first place (the 1st stage). That is where the perceived complexity of OAuth comes from: it also defines various ways in which the Client can obtain an access token from something that is called an Authorization Server.

So the real difference is that JWT is just a token format, OAuth 2.0 is a protocol (that may use a JWT as a token format).

I don't know anything about jquery so can't help you with that, but as far as Javascript is concerned you have an array of objects, so what you will only be able to access the names & values through each array element. E.g arr[0].name will give you 'k1', arr[1].value will give you 'hi'.

Maybe you want to do something like:

var obj = {};

obj.k1 = "abc";
obj.k2 = "hi";
obj.k3 = "oa";

alert ("obj.k2:" + obj.k2);

1. For TLS handshake troubleshooting please use openssl s_client instead of curl.
2. -msg does the trick!
3. -debug helps to see what actually travels over the socket.
4. -status OCSP stapling should be standard nowadays.

openssl s_client -connect example.com:443 -tls1_2 -status -msg -debug -CAfile <path to trusted root ca pem> -key <path to client private key pem> -cert <path to client cert pem> 

Other useful switches -tlsextdebug -prexit -state

Gagravarr's answer is quite good!

Check if an excel cell is empty

But if you assume that a cell is also empty if it contains an empty String (""), you need some additional code. This can happen, if a cell was edited and then not cleared properly (for how to clear a cell properly, see further below).

I wrote myself a helper to check if an XSSFCell is empty (including an empty String).

 /**
 * Checks if the value of a given {@link XSSFCell} is empty.
 * 
 * @param cell
 *            The {@link XSSFCell}.
 * @return {@code true} if the {@link XSSFCell} is empty. {@code false}
 *         otherwise.
 */
public static boolean isCellEmpty(final XSSFCell cell) {
    if (cell == null) { // use row.getCell(x, Row.CREATE_NULL_AS_BLANK) to avoid null cells
        return true;
    }

    if (cell.getCellType() == Cell.CELL_TYPE_BLANK) {
        return true;
    }

    if (cell.getCellType() == Cell.CELL_TYPE_STRING && cell.getStringCellValue().trim().isEmpty()) {
        return true;
    }

    return false;
}

Pay attention for newer POI Version

They first changed getCellType() to getCellTypeEnum() as of Version 3.15 Beta 3 and then moved back to getCellType() as of Version 4.0.

• Version >= 3.15 Beta 3:

  • Use CellType.BLANK and CellType.STRING instead of Cell.CELL_TYPE_BLANK and Cell.CELL_TYPE_STRING

• Version >= 3.15 Beta 3 && Version < 4.0

  • Use Cell.getCellTypeEnum() instead of Cell.getCellType()

But better double check yourself, because they planned to change it back in future releases.

Example

This JUnit test shows the case in which the additional empty check is needed.

Scenario: the content of a cell is changed within a Java program. Later on, in the same Java program, the cell is checked for emptiness. The test will fail if the isCellEmpty(XSSFCell cell) function doesn't check for empty Strings.

@Test
public void testIsCellEmpty_CellHasEmptyString_ReturnTrue() {
    // Arrange
    XSSFCell cell = new XSSFWorkbook().createSheet().createRow(0).createCell(0);

    boolean expectedValue = true;
    boolean actualValue;

    // Act
    cell.setCellValue("foo");
    cell.setCellValue("bar");
    cell.setCellValue(" ");
    actualValue = isCellEmpty(cell);

    // Assert
    Assert.assertEquals(expectedValue, actualValue);
}

In addition: Clear a cell properly

Just in case if someone wants to know, how to clear the content of a cell properly. There are two ways to archive that (I would recommend way 1).

// way 1
public static void clearCell(final XSSFCell cell) {
    cell.setCellType(Cell.CELL_TYPE_BLANK);
}

// way 2
public static void clearCell(final XSSFCell cell) {
    String nullString = null;
    cell.setCellValue(nullString); 
}

Why way 1? Explicit is better than implicit (thanks, Python)

Way 1: sets the cell type explicitly back to blank.
Way 2: sets the cell type implicitly back to blank due to a side effect when setting a cell value to a null String.

you should use []

var x = ConfigurationManager.AppSettings["APIKey"];

See the above definition where it states that a callback function is passed off to some other function and at some point it is called.

In C++ it is desirable to have callback functions call a classes method. When you do this you have access to the member data. If you use the C way of defining a callback you will have to point it to a static member function. This is not very desirable.

Here is how you can use callbacks in C++. Assume 4 files. A pair of .CPP/.H files for each class. Class C1 is the class with a method we want to callback. C2 calls back to C1's method. In this example the callback function takes 1 parameter which I added for the readers sake. The example doesn't show any objects being instantiated and used. One use case for this implementation is when you have one class that reads and stores data into temporary space and another that post processes the data. With a callback function, for every row of data read the callback can then process it. This technique cuts outs the overhead of the temporary space required. It is particularly useful for SQL queries that return a large amount of data which then has to be post-processed.

/////////////////////////////////////////////////////////////////////
// C1 H file

class C1
{
    public:
    C1() {};
    ~C1() {};
    void CALLBACK F1(int i);
};

/////////////////////////////////////////////////////////////////////
// C1 CPP file

void CALLBACK C1::F1(int i)
{
// Do stuff with C1, its methods and data, and even do stuff with the passed in parameter
}

/////////////////////////////////////////////////////////////////////
// C2 H File

class C1; // Forward declaration

class C2
{
    typedef void (CALLBACK C1::* pfnCallBack)(int i);
public:
    C2() {};
    ~C2() {};

    void Fn(C1 * pThat,pfnCallBack pFn);
};

/////////////////////////////////////////////////////////////////////
// C2 CPP File

void C2::Fn(C1 * pThat,pfnCallBack pFn)
{
    // Call a non-static method in C1
    int i = 1;
    (pThat->*pFn)(i);
}

Path Customization (tested in laravel 7) When a user is successfully authenticated, they will be redirected to the /home URI. You can customize the post-authentication redirect path using the HOME constant defined in your RouteServiceProvider:

public const HOME = '/home';

  $this->db->like('title', 'match', 'before'); 
 // Produces: WHERE title LIKE '%match' 

 $this->db->like('title', 'match', 'after'); 
// Produces: WHERE title LIKE 'match%' 

$this->db->like('title', 'match', 'both'); 
// Produces: WHERE title LIKE '%match%'

Just add vertical-align:top for first td alone needed not for all td.

tr>td:first-child {_x000D_
  vertical-align: top;_x000D_
}

<tr>_x000D_
  <td>Description</td>_x000D_
  <td>more text</td>_x000D_
</tr>

Use

git clone --depth=1 --branch=master git://someserver/somerepo dirformynewrepo
rm -rf ./dirformynewrepo/.git

• The depth option will make sure to copy the least bit of history possible to get that repo.
• The branch option is optional and if not specified would get master.
• The second line will make your directory dirformynewrepo not a Git repository any more.
• If you're doing recursive submodule clone, the depth and branch parameter don't apply to the submodules.

http://en.wikipedia.org/wiki/Representational_State_Transfer

REST was initially described in the context of HTTP, but is not limited to that protocol. RESTful architectures can be based on other Application Layer protocols if they already provide a rich and uniform vocabulary for applications based on the transfer of meaningful representational state. RESTful applications maximise the use of the pre-existing, well-defined interface and other built-in capabilities provided by the chosen network protocol, and minimise the addition of new application-specific features on top of it.

http://www.looselycoupled.com/glossary/SOAP

(Simple Object Access Protocol) The standard for web services messages. Based on XML, SOAP defines an envelope format and various rules for describing its contents. Seen (with WSDL and UDDI) as one of the three foundation standards of web services, it is the preferred protocol for exchanging web services, but by no means the only one; proponents of REST say that it adds unnecessary complexity.

Now you can use just window.scrollTo({ top: 0, behavior: 'smooth' }) to get the page scrolled with a smooth effect.

const btn = document.getElementById('elem');_x000D_
_x000D_
btn.addEventListener('click', () => window.scrollTo({_x000D_

Log to Twitter

Based on this post about a log4net Twitter Appender, I thought I would try my hand at writing a NLog Twitter Target (using NLog 1.0 refresh, not 2.0). Alas, so far I have not been able to get a Tweet to actually post successfully. I don't know if it is something wrong in my code, Twitter, our company's internet connection/firewall, or what. I am posting the code here in case someone is interested in trying it out. Note that there are three different "Post" methods. The first one that I tried is PostMessageToTwitter. PostMessageToTwitter is essentially the same as PostLoggingEvent in the orignal post. If I use that I get a 401 exception. PostMessageBasic gets the same exception. PostMessage runs with no errors, but the message still does not make it up to Twitter. PostMessage and PostMessageBasic are based on examples that I found here on SO.

FYI - I just now found a comment by @Jason Diller to an answer in this post that says that twitter is going to turn off basic authentication "next month". This was back in May 2010 and it is now December 2010, so I guess that could be why this is not working.

    <target name="twitter" type="TwitterTarget" TwitterUserName="yourtwittername" TwitterPassword="yourtwitterpassword" layout="${longdate} ${logger} ${level} ${message}" />
</targets>

If someone tries this out and has success, post back with your findings.

You'll have to include/require the class anyway, otherwise PHP won't know about the namespace.
You don't necessary have to do it in the same file though. You can do it in a bootstrap file for example. (or use an autoloader, but that's not the topic actually)

Hope this helps: http://nrecursions.blogspot.in/2014/02/how-to-trigger-jenkins-build-on-git.html

It's just a matter of using curl to trigger a Jenkins job using the git hooks provided by git.
The command

curl http://localhost:8080/job/someJob/build?delay=0sec

can run a Jenkins job, where someJob is the name of the Jenkins job.

Search for the hooks folder in your hidden .git folder. Rename the post-commit.sample file to post-commit. Open it with Notepad, remove the : Nothing line and paste the above command into it.

That's it. Whenever you do a commit, Git will trigger the post-commit commands defined in the file.

1. ADD THIS

**<HEAD>**

  < link rel="icon" href="directory/image.png">

Then run and enjoy it

If you want 08:30 ( HH:MM) format then try this,

SELECT EmplID
    , EmplName
    , InTime
    , [TimeOut]
    , [DateVisited]
    ,  RIGHT('0' + CONVERT(varchar(3),DATEDIFF(minute,InTime, TimeOut)/60),2) + ':' +
      RIGHT('0' + CONVERT(varchar(2),DATEDIFF(minute,InTime,TimeOut)%60),2)
      as TotalHours from times Order By EmplID, DateVisited

A regular expression will do the trick with very little code:

import re

...

if re.match("^[A-Za-z0-9_-]*$", my_little_string):
    # do something here

HTML 4 does not make it explicit. The current HTML5 working draft specifies that the first submit button must be the default:

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

Have you ever tried to do this? :p

var str = '3.8';ie
alert( +(str) + 0.2 );

+(string) will cast string into float.

Handy!

So in order to solve your problem, you can do something like this:

var floatValue = +(str.replace(/,/,'.'));

I'd recommend using NSString for strings that you want to manipulate. Actually come to think of it as a developer I've never run into a problem with NSString that Swift String would solve... I understand the subtleties. But I've yet to have an actual need for them.

var foo = someSwiftString as NSString

or

var foo = "Foo" as NSString

or

var foo: NSString = "blah"

And then the whole world of simple NSString string operations is open to you.

As answer to the question

// check bounds before you do this, e.g. foo.length > 0
// Note shortFoo is of type NSString
var shortFoo = foo.substringToIndex(foo.length-1)

You can annotate your bean with jaxb annotations.

  @XmlRootElement
  public class MyJaxbBean {
    public String name;
    public int age;

    public MyJaxbBean() {} // JAXB needs this

    public MyJaxbBean(String name, int age) {
      this.name = name;
      this.age = age;
    }
  }

and then your method would look like this:

   @GET @Produces("application/json")
   public MyJaxbBean getMyBean() {
      return new MyJaxbBean("Agamemnon", 32);
   }

There is a chapter in the latest documentation that deals with this:

Sorry I know this is an old one but still felt like helping out ^_^

Maybe it's the way I read this but assuming the excel sheet 1 is called "London" and has this information; B5="Marleybone" B6="Paddington" B7="Victoria" B8="Hammersmith". And the excel sheet 2 is called "Nottingham" and has this information; C5="Alverton" C6="Annesley" C7="Arnold" C8="Askham". Then I think this code below would work. ^_^

$xlCellTypeLastCell = 11 
$startRow = 5

$excel = new-object -com excel.application
$wb = $excel.workbooks.open("C:\users\administrator\my_test.xls")

for ($i = 1; $i -le $wb.sheets.count; $i++)
    {
        $sh = $wb.Sheets.Item($i)
        $endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
        $col = $col + $i - 1
        $city = $wb.Sheets.Item($i).name
        $rangeAddress = $sh.Cells.Item($startRow, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
        $sh.Range($rangeAddress).Value2 | foreach{
            New-Object PSObject -Property @{City = $city; Area=$_}
        }
    }

$excel.Workbooks.Close()

This should be the output (without the commas):

City, Area
---- ----
London, Marleybone
London, Paddington
London, Victoria
London, Hammersmith
Nottingham, Alverton
Nottingham, Annesley
Nottingham, Arnold
Nottingham, Askham

Andy E is correct that there is no HTML-based way to do this*; but if you are willing to use Flash, you can do it. The following works reliably on systems that have Flash installed. If your app needs to work on iPhone, then of course you'll need a fallback HTML-based solution.

* (Update 4/22/2013: HTML does now support this, in HTML5. See the other answers.)

Flash uploading also has other advantages -- Flash gives you the ability to show a progress bar as the upload of a large file progresses. (I'm pretty sure that's how Gmail does it, by using Flash behind the scenes, although I may be wrong about that.)

Here is a sample Flex 4 app that allows the user to pick a file, and then displays it:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
               creationComplete="init()">
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:Button x="10" y="10" label="Choose file..." click="showFilePicker()" />
    <mx:Image id="myImage" x="9" y="44"/>
    <fx:Script>
        <![CDATA[
            private var fr:FileReference = new FileReference();

            // Called when the app starts.
            private function init():void
            {
                // Set up event handlers.
                fr.addEventListener(Event.SELECT, onSelect);
                fr.addEventListener(Event.COMPLETE, onComplete);
            }

            // Called when the user clicks "Choose file..."
            private function showFilePicker():void
            {
                fr.browse();
            }

            // Called when fr.browse() dispatches Event.SELECT to indicate
            // that the user has picked a file.
            private function onSelect(e:Event):void
            {
                fr.load(); // start reading the file
            }

            // Called when fr.load() dispatches Event.COMPLETE to indicate
            // that the file has finished loading.
            private function onComplete(e:Event):void
            {
                myImage.data = fr.data; // load the file's data into the Image
            }
        ]]>
    </fx:Script>
</s:Application>

Chances are, you'll have cut as well. If so:

[me@home]$ echo "pid: 1234" | cut -d" " -f2
1234

You could use a variable to make the calculation and use toFixed when you set the #diskamountUnit element value:

var amount = $("#disk").slider("value") * 1.60;
$("#diskamountUnit").val('$' + amount.toFixed(2));

You can also do that in one step, in the val method call but IMO the first way is more readable:

$("#diskamountUnit").val('$' + ($("#disk").slider("value") * 1.60).toFixed(2));

Mockito [3.4.0] can mock static methods!

1. Replace mockito-core dependency with mockito-inline:3.4.0.

2. Class with static method:

   class Buddy {
     static String name() {
       return "John";
     }
   }
   

3. Use new method Mockito.mockStatic():

   @Test
   void lookMomICanMockStaticMethods() {
     assertThat(Buddy.name()).isEqualTo("John");
   
     try (MockedStatic<Buddy> theMock = Mockito.mockStatic(Buddy.class)) {
       theMock.when(Buddy::name).thenReturn("Rafael");
       assertThat(Buddy.name()).isEqualTo("Rafael");
     }
   
     assertThat(Buddy.name()).isEqualTo("John");
   }
   

   Mockito replaces the static method within the try block only.

What I do in my Asp Net Core Api applications it is to create a class that extends from ObjectResult and provide many constructors to customize the content and the status code. Then all my Controller actions use one of the costructors as appropiate. You can take a look at my implementation at: https://github.com/melardev/AspNetCoreApiPaginatedCrud

and

https://github.com/melardev/ApiAspCoreEcommerce

here is how the class looks like(go to my repo for full code):

public class StatusCodeAndDtoWrapper : ObjectResult
{



    public StatusCodeAndDtoWrapper(AppResponse dto, int statusCode = 200) : base(dto)
    {
        StatusCode = statusCode;
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, string message) : base(dto)
    {
        StatusCode = statusCode;
        if (dto.FullMessages == null)
            dto.FullMessages = new List<string>(1);
        dto.FullMessages.Add(message);
    }

    private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, ICollection<string> messages) : base(dto)
    {
        StatusCode = statusCode;
        dto.FullMessages = messages;
    }
}

Notice the base(dto) you replace dto by your object and you should be good to go.

Try This it worked like a charm for me,

Objective C

I have set RGB gradient background Color to UIview

   UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,35)];
   CAGradientLayer *gradient = [CAGradientLayer layer];
   gradient.frame = view.bounds;
   gradient.startPoint = CGPointZero;
   gradient.endPoint = CGPointMake(1, 1);
   gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor colorWithRed:34.0/255.0 green:211/255.0 blue:198/255.0 alpha:1.0] CGColor],(id)[[UIColor colorWithRed:145/255.0 green:72.0/255.0 blue:203/255.0 alpha:1.0] CGColor], nil];
   [view.layer addSublayer:gradient];

UPDATED :- Swift3 +

Code :-

 var gradientView = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 35))
 let gradientLayer:CAGradientLayer = CAGradientLayer()
 gradientLayer.frame.size = self.gradientView.frame.size
 gradientLayer.colors = 
 [UIColor.white.cgColor,UIColor.red.withAlphaComponent(1).cgColor] 
//Use diffrent colors
 gradientView.layer.addSublayer(gradientLayer)

You can add starting and end point of gradient color.

  gradientLayer.startPoint = CGPoint(x: 0.0, y: 1.0)
  gradientLayer.endPoint = CGPoint(x: 1.0, y: 1.0)

For more details description refer CAGradientLayer Doc

Hope this is help for some one .

This error message appeared for me when I tried to debug two solutions at the same time as I wanted to visually compare the differences. Unchecking the Enable JavaScript Debugging for ASP.NET (Chrome and IE) option worked, but I am still confused why I could not debug more than one solution at a time. Since it is a known issue, maybe this will be address in an update from Visual Studio. Here is to hoping ....

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

"localhost" is normally the hostname for the 127.0.0.1 IP address. It's usually set in /etc/hosts (or the Windows equivalent named "hosts" somewhere under %WINDIR%). You can use it just like any other hostname - try "ping localhost" to see how it resolves to 127.0.0.1.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

That hopefully answers the IP side of your question. I'm not familiar with Jekyll or Vagrant, but I'm guessing that your port forwarding 8080 => 4000 is somehow bound to a particular network adapter, so it isn't in the path when you connect locally to 127.0.0.1

For me, It's working like this one.

C:\Program Files\PostgreSQL\12\bin> psql -U postgres -p 5432  -d dummy -f C:\Users\Downloads\d2cm_test.sql

function removeRow(row) {
    $(row).remove();
}

<tr onmousedown="removeRow(this)"><td>Foo</td></tr>

Maybe something like this could work as well? I haven't tried doing something with "this", so I don't know if it works or not.

Use a T-SQL IF:

IF @ABC IS NOT NULL AND @ABC != -1
    UPDATE [TABLE_NAME] SET XYZ=@ABC

Take a look at the MSDN docs.

I was having the same issue and none of the above made any difference for me what did work was having my location php above any other location blocks.

location ~ [^/]\.php(/|$) {
fastcgi_split_path_info  ^(.+\.php)(/.+)$;
fastcgi_index            index.php;
fastcgi_pass             unix:/var/run/php/php7.3-fpm.sock;
include                  fastcgi_params;
fastcgi_param   PATH_INFO       $fastcgi_path_info;
fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
** The below is specifically for moodle **
location /dataroot/ {
internal;
alias <full_moodledata_path>; # ensure the path ends with /
}

With the release of Mercurial 2.2, you can use the --amend option with hg commit to update the last commit with the current working directory

From the command line reference:

The --amend flag can be used to amend the parent of the working directory with a new commit that contains the changes in the parent in addition to those currently reported by hg status, if there are any. The old commit is stored in a backup bundle in .hg/strip-backup (see hg help bundle and hg help unbundle on how to restore it).

Message, user and date are taken from the amended commit unless specified. When a message isn't specified on the command line, the editor will open with the message of the amended commit.

The great thing is that this mechanism is "safe", because it relies on the relatively new "Phases" feature to prevent updates that would change history that's already been made available outside of the local repository.

You will have to use something like below

#menu ul{_x000D_
  list-style: none;_x000D_
}_x000D_
#menu li{_x000D_
  display: inline;_x000D_
}_x000D_
 

<div id="menu">_x000D_
  <ul>_x000D_
    <li>First menu item</li>_x000D_
    <li>Second menu item</li>_x000D_
    <li>Third menu item</li>_x000D_
  </ul>_x000D_
</div>

In order to answer you questions;

"?v=1" this is written only beacuse to download a fresh copy of the css and js files instead of using from the cache of the browser.

If you mention this query string parameter at the end of your stylesheet or the js file then it forces the browser to download a new file, Due to which the recent changes in the .css and .js files are made effetive in your browser.

If you dont use this versioning then you may need to clear the cache of refresh the page in order to view the recent changes in those files.

Here is an article that explains this thing How and Why to make versioning of CSS and JS files

What about creating an additional wrapper class?

package com.naveen.research.sql;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public abstract class PreparedStatementWrapper implements AutoCloseable {

    protected PreparedStatement stat;

    public PreparedStatementWrapper(Connection con, String query, Object ... params) throws SQLException {
        this.stat = con.prepareStatement(query);
        this.prepareStatement(params);
    }

    protected abstract void prepareStatement(Object ... params) throws SQLException;

    public ResultSet executeQuery() throws SQLException {
        return this.stat.executeQuery();
    }

    public int executeUpdate() throws SQLException {
        return this.stat.executeUpdate();
    }

    @Override
    public void close() {
        try {
            this.stat.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Then in the calling class you can implement prepareStatement method as:

try (Connection con = DriverManager.getConnection(JDBC_URL, prop);
    PreparedStatementWrapper stat = new PreparedStatementWrapper(con, query,
                new Object[] { 123L, "TEST" }) {
            @Override
            protected void prepareStatement(Object... params) throws SQLException {
                stat.setLong(1, Long.class.cast(params[0]));
                stat.setString(2, String.valueOf(params[1]));
            }
        };
        ResultSet rs = stat.executeQuery();) {
    while (rs.next())
        System.out.println(String.format("%s, %s", rs.getString(2), rs.getString(1)));
} catch (SQLException e) {
    e.printStackTrace();
}

Points To Remember:

--> No spaces in src

--> Remember to use single quotation in double quotation for src

@user1417684 and @chris-foster are right!

excerpt from working code (without error handling):

var SubItemModel = mongoose.model('subitems', SubItemSchema);
var ItemModel    = mongoose.model('items', ItemSchema);

var new_sub_item_model = new SubItemModel(new_sub_item_plain);
new_sub_item_model.save(function (error, new_sub_item) {

  var new_item = new ItemModel(new_item);
  new_item.subitem = new_sub_item._id;
  new_item.save(function (error, new_item) {
    // so this is a valid way to populate via the Model
    // as documented in comments above (here @stack overflow):
    ItemModel.populate(new_item, { path: 'subitem', model: 'subitems' }, function(error, new_item) {
      callback(new_item.toObject());
    });
    // or populate directly on the result object
    new_item.populate('subitem', function(error, new_item) {
      callback(new_item.toObject());
    });
  });

});

Obviously, the syntax are completely different (Groovy is closest to Java), but I suppose that is not what you are asking for.

If you are interested in using them to script a Java application, Scala is probably not a good choice, as there is no easy way to evaluate it from Java, whereas Groovy is especially suited for that purpose.

Try this:

change line 4 to: mysql_connect("localhost","root","enter password here");
change line 64 to: if(!mysql_connect("localhost","root","enter password here"))

From here

it is because view child require two argument try like this

@ViewChild('nameInput', { static: false, }) nameInputRef: ElementRef;

@ViewChild('amountInput', { static: false, }) amountInputRef: ElementRef;

If you need to change the bottom position of the modal, you need to modify the max-height of the modal-body:

.modal-body {
  max-height: 75vh;
}

As other answers have said, you can adjust the right and top on the modal-dialog :

.modal-dialog {
  top: 10vh;
  right: 5vw;
}

• "vh" means "% of view height"
• "vw" means "% of view width"

You could "simulate" shifting and masking: if((0x5e/(2*2*2))%2) ...

The venerable DateJS library has a formatting routine (it overrides ".toString()"). You could also do one yourself pretty easily because the "Date" methods give you all the numbers you need.

You could use

Calendar cal = Calendar.getInstance();
cal.setTime(beginupd);
long millis = cal.getTimeInMillis();

If cleaning the solution didn't work and for anybody who see's this question and tried moving a project or renaming.

Open Package manager console and type "dotnet restore".

Here is a more complete way.

1. Get the timezone offset for the user
2. Test some days on daylight saving boundaries to determine if they are in a zone that uses daylight saving.

An excerpt is below:

function TimezoneDetect(){
    var dtDate = new Date('1/1/' + (new Date()).getUTCFullYear());
    var intOffset = 10000; //set initial offset high so it is adjusted on the first attempt
    var intMonth;
    var intHoursUtc;
    var intHours;
    var intDaysMultiplyBy;

    // Go through each month to find the lowest offset to account for DST
    for (intMonth=0;intMonth < 12;intMonth++){
        //go to the next month
        dtDate.setUTCMonth(dtDate.getUTCMonth() + 1);

        // To ignore daylight saving time look for the lowest offset.
        // Since, during DST, the clock moves forward, it'll be a bigger number.
        if (intOffset > (dtDate.getTimezoneOffset() * (-1))){
            intOffset = (dtDate.getTimezoneOffset() * (-1));
        }
    }

    return intOffset;
}

unsigned char takes only positive values: 0 to 255 while signed char takes positive and negative values: -128 to +127.

I'm a new-ish R user and thought I'd post this in case it helps anyone else. I was trying to read in data from a text file (separated with commas) that included a few Spanish characters and it took me forever to figure it out. I knew I needed to use UTF-8 encoding, set the header arg to TRUE, and that I need to set the sep arguemnt to ",", but then I still got hang ups. After reading this post I tried setting the fill arg to TRUE, but then got the same "EOF within quoted string" which I was able to fix in the same manner as above. My successful read.table looks like this:

target <- read.table("target2.txt", fill=TRUE, header=TRUE, quote="", sep=",", encoding="UTF-8")

The result has Spanish language characters and same dims I had originally, so I'm calling it a success! Thanks all!

In this case, to validate Date (DD-MM-YYYY) or (DD/MM/YYYY), with a year between 1900 and 2099,like this with month and Days validation

if (!Regex.Match(txtDob.Text, @"^(0[1-9]|1[0-9]|2[0-9]|3[0,1])([/+-])(0[1-9]|1[0-2])([/+-])(19|20)[0-9]{2}$").Success)                  
{
   MessageBox.Show("InValid Date of Birth");
   txtDob.Focus();
}
