Zookeeper is one of the best open source server and service that helps to reliably coordinates distributed processes. Zookeeper is a CP system (Refer CAP Theorem) that provides Consistency and Partition tolerance. Replication of Zookeeper state across all the nodes makes it an eventually consistent distributed service.

Moreover, any newly elected leader will update its followers with missing proposals or with a snapshot of the state, if the followers have many proposals missing.

Zookeeper also provides an API that is very easy to use. This blog post, Zookeeper Java API examples, has some examples if you are looking for examples.

So where do we use this? If your distributed service needs a centralized, reliable and consistent configuration management, locks, queues etc, you will find Zookeeper a reliable choice.

To all the great answers I would like to add that repartition is one the best option to take advantage of data parallelization. While coalesce gives a cheap option to reduce the partitions and it is very useful when writing data to HDFS or some other sink to take advantage of big writes.

I have found this useful when writing data in parquet format to get full advantage.

There is no difference. From RDD.scala.

/** Persist this RDD with the default storage level (`MEMORY_ONLY`). */
def persist(): this.type = persist(StorageLevel.MEMORY_ONLY)

/** Persist this RDD with the default storage level (`MEMORY_ONLY`). */
def cache(): this.type = persist()

I'm surprised that nobody has mentioned the use of this in the event handler. It works automatically in modern browsers and can be made to work in other browsers. If you use addEventListener or attachEvent to install your event handler, then you can make the value of this automatically be assigned to the object the created the event.

Further, the user of programmatically installed event handlers allows you to separate javascript code from HTML which is often considered a good thing.

Here's how you would do that in your code in plain javascript:

Remove the onmouseover="zoom()" from your HTML and install the event handler in your javascript like this:

// simplified utility function to register an event handler cross-browser
function setEventHandler(obj, name, fn) {
    if (typeof obj == "string") {
        obj = document.getElementById(obj);
    }
    if (obj.addEventListener) {
        return(obj.addEventListener(name, fn));
    } else if (obj.attachEvent) {
        return(obj.attachEvent("on" + name, function() {return(fn.call(obj));}));
    }
}

function zoom() {
    // you can use "this" here to refer to the object that caused the event
    // this here will refer to the calling object (which in this case is the <map>)
    console.log(this.id);
    document.getElementById("preview").src="http://photos.smugmug.com/photos/344290962_h6JjS-Ti.jpg";
}

// register your event handler
setEventHandler("nose", "mouseover", zoom);

I had the same problem. SSMS launches the 32bit version of the import and export wizard which has this issue. Try launching the 64bit version application and it should work fine.

Extend is used when a use case adds steps to another first-class use case.

For example, imagine "Withdraw Cash" is a use case of an Automated Teller Machine (ATM). "Assess Fee" would extend Withdraw Cash and describe the conditional "extension point" that is instantiated when the ATM user doesn't bank at the ATM's owning institution. Notice that the basic "Withdraw Cash" use case stands on its own, without the extension.

Include is used to extract use case fragments that are duplicated in multiple use cases. The included use case cannot stand alone and the original use case is not complete without the included one. This should be used sparingly and only in cases where the duplication is significant and exists by design (rather than by coincidence).

For example, the flow of events that occurs at the beginning of every ATM use case (when the user puts in their ATM card, enters their PIN, and is shown the main menu) would be a good candidate for an include.

These are different Form content types defined by W3C. If you want to send simple text/ ASCII data, then x-www-form-urlencoded will work. This is the default.

But if you have to send non-ASCII text or large binary data, the form-data is for that.

You can use Raw if you want to send plain text or JSON or any other kind of string. Like the name suggests, Postman sends your raw string data as it is without modifications. The type of data that you are sending can be set by using the content-type header from the drop down.

Binary can be used when you want to attach non-textual data to the request, e.g. a video/audio file, images, or any other binary data file.

Refer to this link for further reading: Forms in HTML documents

One wrinkle I ran into (that isn't covered in other answers):

Suppose you have these namespaces:

• Something.Other
• Parent.Something.Other

When you use using Something.Other outside of a namespace Parent, it refers to the first one (Something.Other).

However if you use it inside of that namespace declaration, it refers to the second one (Parent.Something.Other)!

There is a simple solution: add the "global::" prefix: docs

namespace Parent
{
   using global::Something.Other;
   // etc
}

If you want to execute any procedure then firstly you have to set serveroutput on in the sqldeveloper work environment like.

->  SET SERVEROUTPUT ON;
-> BEGIN
dbms_output.put_line ('Hello World..');
dbms_output.put_line('Its displaying the values only for the Testing purpose');
END;
/

why not use background-color: #ff0000; opacity: 0.5; filter: alpha(opacity=50); /* in IE */

if you target a color for a text or probably an element, this should be a lot easier to do.

Good news for developers who is working with latest version of visual studio

The Web Essentials are coming with this feature .

Check this out

Note: For VS 2017 use JavaScript Regions : https://marketplace.visualstudio.com/items?itemName=MadsKristensen.JavaScriptRegions

You're in replace mode. Press the Insert key on your keyboard to switch back to insert mode. Many applications that handle text have this in common.

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

Both SAX and DOM are used to parse the XML document. Both has advantages and disadvantages and can be used in our programming depending on the situation

SAX:

1. Parses node by node

2. Does not store the XML in memory

3. We cant insert or delete a node

4. Top to bottom traversing

DOM

1. Stores the entire XML document into memory before processing

2. Occupies more memory

3. We can insert or delete nodes

4. Traverse in any direction.

If we need to find a node and does not need to insert or delete we can go with SAX itself otherwise DOM provided we have more memory.

If you install your mysql with apt install mysql.
you can just login to your mysql with sudo mysql.

I'd like to add to this the enormously simple, but oh so easily made mistake of writing:

this.state.something = 'changed';

... and then not understanding why it's not rendering and Googling and coming on this page, only to realize that you should have written:

this.setState({something: 'changed'});

React only triggers a re-render if you use setState to update the state.

<input type="button" /> buttons will not submit a form - they don't do anything by default. They're generally used in conjunction with JavaScript as part of an AJAX application.

<input type="submit"> buttons will submit the form they are in when the user clicks on them, unless you specify otherwise with JavaScript.

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']

I'm not a git expert, but I think this should work:

git clone http://git.abc.net/git/abc.git
cd abc
git checkout my_abc 

OR

git clone http://git.abc.net/git/abc.git
cd abc
git checkout -b new_branch my_abc

The second variation establishes a new branch based on the tag, which lets you avoid a 'detached HEAD'. (git-checkout manual)

Every git repo contains the entire revision history, so cloning the repo gives you access to the latest commit, plus everything that came before, including the tag you're looking for.

One more thing - if You edited the shell script in some Windows text editor, which produces the \r\n line-endings, cygwin's bash wouldn't accept those \r. Just run dos2unix testit.sh before executing the script:

C:\cygwin\bin\dos2unix testit.sh
C:\cygwin\bin\bash testit.sh

I much prefer the array module to the struct module for this kind of tasks (ones involving sequences of homogeneous values):

>>> import array
>>> array.array('B', [17, 24, 121, 1, 12, 222, 34, 76]).tostring()
'\x11\x18y\x01\x0c\xde"L'

no len call, no string manipulation needed, etc -- fast, simple, direct, why prefer any other approach?!

Android makes it easy.

public void setTabTextColors(int normalColor, int selectedColor) {
    setTabTextColors(createColorStateList(normalColor, selectedColor));
}

So, we just say

mycooltablayout.setTabTextColors(Color.parseColor("#1464f4"), Color.parseColor("#880088"));

That will give us a blue normal color and purple selected color.

Now we set the height

public void setSelectedTabIndicatorHeight(int height) {
    mTabStrip.setSelectedIndicatorHeight(height);
}

And for height we say

mycooltablayout.setSelectedIndicatorHeight(6);

No need to use string functions. You can use something that's actually designed for what you want: pathinfo():

$path = $_FILES['image']['name'];
$ext = pathinfo($path, PATHINFO_EXTENSION);

This code implements the logic of how search works (one of the ways) without using any ready-made function:

public int findSubString(char[] original, char[] searchString)
{
    int returnCode = 0; //0-not found, -1 -error in imput, 1-found
    int counter = 0;
    int ctr = 0;
    if (original.Length < 1 || (original.Length)<searchString.Length || searchString.Length<1)
    {
        returnCode = -1;
    }

    while (ctr <= (original.Length - searchString.Length) && searchString.Length > 0)
    {
        if ((original[ctr]) == searchString[0])
        {
            counter = 0;
            for (int count = ctr; count < (ctr + searchString.Length); count++)
            {
                if (original[count] == searchString[counter])
                {
                    counter++;
                }
                else
                {
                    counter = 0;
                    break;
                }
            }
            if (counter == (searchString.Length))
            {
                returnCode = 1;
            }
        }
        ctr++;
    }
    return returnCode;
}

If the response code isn't 200 or 2xx, use getErrorStream() instead of getInputStream().

The better and correct solution is to have a directive. The scope is the same, whether in the controller of the directive or the main controller. Use $element to do DOM operations. The method defined in the directive controller is accessible in the main controller.

Example, finding a child element:

var app = angular.module('myapp', []);
app.directive("testDir", function () {
    function link(scope, element) { 

    }
    return {
        restrict: "AE", 
        link: link, 
        controller:function($scope,$element){
            $scope.name2 = 'this is second name';
            var barGridSection = $element.find('#barGridSection'); //helps to find the child element.
    }
    };
})

app.controller('mainController', function ($scope) {
$scope.name='this is first name'
});

I was has same problem and i solved using the below code :

(change)="onChange($event.target.value)"

I've been searching answer but couldn't find but finally I could fix this by adding play-service-ads dependency let's try this

*) File -> Project Structure... -> Under the module you can find app and there is a option called dependencies and you can add com.google.android.gms:play-services-ads:x.x.x dependency to your project

I faced this problem when I try to import eclipse project into android studio

Click here to see screenshot

Try this it may help you:

private void changeFragment(Fragment targetFragment){

    getSupportFragmentManager()
         .beginTransaction()
         .replace(R.id.main_fragment, targetFragment, "fragment")
         .setTransitionStyle(FragmentTransaction.TRANSIT_FRAGMENT_FADE)
         .commit();

}

The easiest way would be:

String[] myArray = ...;
List<String> strs = Arrays.asList(myArray);

using the handy Arrays utility class. Note, that you can even do

List<String> strs = Arrays.asList("a", "b", "c");

They are Synonyms. No Difference At all

Sticky Session / Session Affinity:

Affinity/Stickiness/Contact between user session and, the server to which user request is sent is retained.

For the benefit of searchers; if you are using jQuery, you can do the following:

var currentOverride = $('#customoverridestyles');

if (currentOverride) {
 currentOverride.remove();
}

$('body').append("<style id=\"customoverridestyles\">body{background-color:pink;}</style>");

Obviously you can change the inner css to whatever you want.

Appreciate some people prefer pure JavaScript, but it works and has been pretty robust for writing/overwriting styles dynamically.

Another Solution : you get the marker by its title

public class MarkerDemoActivity extends android.support.v4.app.FragmentActivity implements OnMarkerClickListener
{
      private Marker myMarker;    

      private void setUpMap()
      {
      .......
      googleMap.setOnMarkerClickListener(this);

      myMarker = googleMap.addMarker(new MarkerOptions()
                  .position(latLng)
                  .title("My Spot")
                  .snippet("This is my spot!")
                  .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
      ......
      }

  @Override
  public boolean onMarkerClick(final Marker marker) 
  {

     String name= marker.getTitle();

      if (name.equalsIgnoreCase("My Spot")) 
      {
          //write your code here
      }
  }
}

i had this issue, and fixed it. the problem seemed to be this:

wrong:

<add key="aaa" value="server=[abc\SQL2K8];database=bbb;uid=ccc;password=ddd;" />

right

<add key="aaa" value="server=abc\SQL2K8;database=bbb;uid=ccc;password=ddd;" />

It is amusing to return 418 I'm a teapot to requests that are obviously crafted or malicious and "can't happen", such as failing CSRF check or missing request properties.

2.3.2 418 I'm a teapot

Any attempt to brew coffee with a teapot should result in the error code "418 I'm a teapot". The resulting entity body MAY be short and stout.

To keep it reasonably serious, I restrict usage of funny error codes to RESTful endpoints that are not directly exposed to the user.

The following is something I used that worked for me across browsers so I hope it helps someone in the future:

#contentblock th:first-child {
    -moz-border-radius: 6px 0 0 0;
    -webkit-border-radius: 6px 0 0 0;
    border-radius: 6px 0 0 0;
    behavior: url(/images/border-radius.htc);
    border-radius: 6px 0 0 0;
}

#contentblock th:last-child {
    -moz-border-radius: 0 6px 0 0;
    -webkit-border-radius: 0 6px 0 0;
    border-radius: 0 6px 0 0;
    behavior: url(/images/border-radius.htc);
    border-radius: 0 6px 0 0;
}
#contentblock tr:last-child td:last-child {
     border-radius: 0 0 6px 0;
    -moz-border-radius: 0 0 6px 0;
    -webkit-border-radius: 0 0 6px 0;
    behavior: url(/images/border-radius.htc);
    border-radius: 0 0 6px 0;
 }

#contentblock tr:last-child td:first-child {
    -moz-border-radius: 0 0 0 6px;
    -webkit-border-radius: 0 0 0 6px;
    border-radius: 0 0 0 6px;
    behavior: url(/images/border-radius.htc);
    border-radius: 0 0 0 6px;
}

Obviously the #contentblock portion can be replaced/edited as needed and you can find the border-radius.htc file by doing a search in Google or your favorite web browser.

you have an array of int which is a primitive type, primitive type doesn't have the method add. You should look for Collections.

You could simply add a click listener on the map inside the function that creates the InfoWindow

google.maps.event.addListener(marker, 'click', function() {
    var infoWindow = createInfoWindowForMarker(marker);
    infoWindow.open(map, marker);
    google.maps.event.addListener(map, 'click', function() {
        infoWindow.close();
    });
});

The server at x3.chatforyoursite.com needs to output the following header:

Access-Control-Allow-Origin: http://www.example.com

Where http://www.example.com is your website address. You should check your settings on chatforyoursite.com to see if you can enable this - if not their technical support would probably be the best way to resolve this. However to answer your question, you need the remote site to allow your site to access AJAX responses client side.

I did an upgraded version of jezzipin's answer (and I'm animating padding top instead of height but you still get the point.

Increasing the heap size is not a "fix" it is a "plaster", 100% temporary. It will crash again in somewhere else. To avoid these issues, write high performance code.

1. Use local variables wherever possible.
2. Make sure you select the correct object (EX: Selection between String, StringBuffer and StringBuilder)
3. Use a good code system for your program(EX: Using static variables VS non static variables)
4. Other stuff which could work on your code.
5. Try to move with multy THREADING

Bootstrap 4.0

Be aware of all migration changes from Bootstrap 3 to 4. On the table you now need to enable flex box by adding the class d-flex, and drop the xs to allow bootstrap to automatically detect the viewport.

<div class="container-fluid">
    <table id="productSizes" class="table">
        <thead>
            <tr class="d-flex">
                <th class="col-1">Size</th>
                <th class="col-3">Bust</th>
                <th class="col-3">Waist</th>
                <th class="col-5">Hips</th>
            </tr>

Bootstrap 3.2

Table column width use the same layout as grids do; using col-[viewport]-[size]. Remember the column sizes should total 12; 1 + 3 + 3 + 5 = 12 in this example.

        <thead>
            <tr>
                <th class="col-xs-1">Size</th>
                <th class="col-xs-3">Bust</th>
                <th class="col-xs-3">Waist</th>
                <th class="col-xs-5">Hips</th>
            </tr>
        </thead>

Remember to set the <th> elements rather than the <td> elements so it sets the whole column. Here is a working BOOTPLY.

Thanks to @Dan for reminding me to always work mobile view (col-xs-*) first.

I can run on my device at last, just I enabled the "USB debugging" and "Allow mock location" options from the Debug Menu of my device.

YOu can also rewrite it like this

FROM Resource r WHERE r.ResourceNo IN
        ( 
            SELECT m.ResourceNo FROM JobMember m
            JOIN Job j ON j.JobNo = m.JobNo
            WHERE j.ProjectManagerNo = @UserResourceNo 
            OR
            j.AlternateProjectManagerNo = @UserResourceNo

            Union All

            SELECT m.ResourceNo FROM JobMember m
            JOIN JobTask t ON t.JobTaskNo = m.JobTaskNo
            WHERE t.TaskManagerNo = @UserResourceNo
            OR
            t.AlternateTaskManagerNo = @UserResourceNo

        )

Also a return table is expected in your RETURN statement

protected void grvSecondaryLocations_RowEditing(object sender, GridViewEditEventArgs e)  
{  
    grvSecondaryLocations.EditIndex = e.NewEditIndex;  

    DropDownList ddlPbx = (DropDownList)(grvSecondaryLocations.Rows[grvSecondaryLocations.EditIndex].FindControl("ddlPBXTypeNS"));
    if (ddlPbx != null)  
    {  
        ddlPbx.DataSource = _pbxTypes;  
        ddlPbx.DataBind();  
    }  

    .... (more stuff)  
}

You could use a javascript snippit

$(function()
{
    // Enable drop menu clicks
    $(".nav li > a").off();
});

That will unbind the click event preventing url changing.

They are hint to the compiler to emit instructions that will cause branch prediction to favour the "likely" side of a jump instruction. This can be a big win, if the prediction is correct it means that the jump instruction is basically free and will take zero cycles. On the other hand if the prediction is wrong, then it means the processor pipeline needs to be flushed and it can cost several cycles. So long as the prediction is correct most of the time, this will tend to be good for performance.

Like all such performance optimisations you should only do it after extensive profiling to ensure the code really is in a bottleneck, and probably given the micro nature, that it is being run in a tight loop. Generally the Linux developers are pretty experienced so I would imagine they would have done that. They don't really care too much about portability as they only target gcc, and they have a very close idea of the assembly they want it to generate.

Use attributed string:

// Define attributes
let labelFont = UIFont(name: "HelveticaNeue-Bold", size: 18)
let attributes :Dictionary = [NSFontAttributeName : labelFont]

// Create attributed string
var attrString = NSAttributedString(string: "Foo", attributes:attributes)
label.attributedText = attrString

You need to define attributes.

Using attributed string you can mix colors, sizes, fonts etc within one text

Use a Java to C# translator on the Java implementation (java.util.PriorityQueue) in the Java Collections framework, or more intelligently use the algorithm and core code and plug it into a C# class of your own making that adheres to the C# Collections framework API for Queues, or at least Collections.

I tried all the above and nothing worked for me. This solved all my problems:

pip install -U numpy

pip install -U scipy

Note that the -U option to pip install requests that the package be upgraded. Without it, if the package is already installed pip will inform you of this and exit without doing anything.

I guess it depends on what you are processing. If you are calculating the FFT over a large duration you might find that it does take a while depending on how many frequency points you are wanting. However, in most cases for audio it is considered non-stationary (that is the signals mean and variance changes to much over time), so taking one large FFT (Periodogram PSD estimate) is not an accurate representation. Alternatively you could use Short-time Fourier transform, whereby you break the signal up into smaller frames and calculate the FFT. The frame size varies depending on how quickly the statistics change, for speech it is usually 20-40ms, for music I assume it is slightly higher.

This method is good if you are sampling from the microphone, because it allows you to buffer each frame at a time, calculate the fft and give what the user feels is "real time" interaction. Because 20ms is quick, because we can't really perceive a time difference that small.

I developed a small bench mark to test the difference between FFTW and KissFFT c-libraries on a speech signal. Yes FFTW is highly optimised, but when you are taking only short-frames, updating the data for the user, and using only a small fft size, they are both very similar. Here is an example on how to implement the KissFFT libraries in Android using LibGdx by badlogic games. I implemented this library using overlapping frames in an Android App I developed a few months ago called Speech Enhancement for Android.

An easy way to overcome this problem is to use 64 bit type

list = numpy.array(list, dtype=numpy.float64)

Like this?

In LINQ:

var sortedList = originalList.OrderBy(foo => !foo.AVC)
                             .ToList();

Or in-place:

originalList.Sort((foo1, foo2) => foo2.AVC.CompareTo(foo1.AVC));

As Jon Skeet says, the trick here is knowing that false is considered to be 'smaller' than true.

If you find that you are doing these ordering operations in lots of different places in your code, you might want to get your type Foo to implement the IComparable<Foo> and IComparable interfaces.

Create a new keypair: (go with the defaults)

ssh-keygen

Copy the public key to the server: (password for the last time)

ssh-copy-id [email protected]

From now on the server should recognize your key and not ask you for the password anymore:

ssh [email protected]

just remove this because constructor don't have a return type like void it will be like this :

private Flow()
    {
        X = x;
        Y = y;
    }  

following code works just fine for me.

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(movieurl));
startActivity(intent);

"[a-zA-Z]" matches only one character. To match multiple characters, use "[a-zA-Z]+".

Since a dot is a joker for any character, you have to mask it: "abc\." To make the dot optional, you need a question mark: "abc\.?"

If you write the Pattern as literal constant in your code, you have to mask the backslash:

System.out.println ("abc".matches ("abc\\.?"));
System.out.println ("abc.".matches ("abc\\.?"));
System.out.println ("abc..".matches ("abc\\.?"));

Combining both patterns:

System.out.println ("abc.".matches ("[a-zA-Z]+\\.?"));

Instead of a-zA-Z, \w is often more appropriate, since it captures foreign characters like äöüßø and so on:

System.out.println ("abc.".matches ("\\w+\\.?"));   

The question title is ambiguous.

• If you need to get a commit, just use this URL: https://github.com/facebook/facebook-ios-sdk/commit/91f256424531030a454548693c3a6ca49ca3f35a.patch (like explain here for the question How to download a single commit-diff from GitHub?)
• if you need to download the entire project at the commit you need, use this URL: https://github.com/facebook/facebook-ios-sdk/archive/91f256424531030a454548693c3a6ca49ca3f35a.zip
• if you need the git revision log, clone the repository and checkout the commit you want.

You'll find debugging errors like this a lot easier if you catch any errors thrown from the execSQL call. eg:

 try 
 {
      db.execSQL(Create_CashBook);  
 }
 catch (Exception e) 
 {
       Log.e("ERROR", e.toString());
 }

Use an interpolated string, this generates a rounded up string:

var strlen = 6;
$"{48.485:F2}"

Output

"48.49"

Here's a one-module Python replacement for perl -p:

# Provide compatibility with `perl -p`

# Usage:
#
#     python -mloop_over_stdin_lines '<program>'

# In, `<program>`, use the variable `line` to read and change the current line.

# Example:
#
#         python -mloop_over_stdin_lines 'line = re.sub("pattern", "replacement", line)'

# From the perlrun documentation:
#
#        -p   causes Perl to assume the following loop around your
#             program, which makes it iterate over filename arguments
#             somewhat like sed:
# 
#               LINE:
#                 while (<>) {
#                     ...             # your program goes here
#                 } continue {
#                     print or die "-p destination: $!\n";
#                 }
# 
#             If a file named by an argument cannot be opened for some
#             reason, Perl warns you about it, and moves on to the next
#             file. Note that the lines are printed automatically. An
#             error occurring during printing is treated as fatal. To
#             suppress printing use the -n switch. A -p overrides a -n
#             switch.
# 
#             "BEGIN" and "END" blocks may be used to capture control
#             before or after the implicit loop, just as in awk.
# 

import re
import sys

for line in sys.stdin:
    exec(sys.argv[1], globals(), locals())
    try:
        print line,
    except:
        sys.exit('-p destination: $!\n')

Please note that, the repeatable in repeatable read regards to a tuple, but not to the entire table. In ANSC isolation levels, phantom read anomaly can occur, which means read a table with the same where clause twice may return different return different result sets. Literally, it's not repeatable.

It is the equivalent to \n -> LF (Line Feed).

Sometimes it is used in HTML and JavaScript. Otherwise in .NET environments, use Environment.NewLine.

You are missing setter for salt property as indicated by the exception

Please add the setter as

You can also use map:

a = [1, 1, 1, 1, 1]
b = 1
list(map(lambda x: x + b, a))

It gives:

[2, 2, 2, 2, 2]

The other answers either present a manual string replacement, URLEncoder which actually encodes for HTML format, Apache's abandoned URIUtil, or using Guava's UrlEscapers. The last one is fine, except it doesn't provide a decoder.

Apache Commons Lang provides the URLCodec, which encodes and decodes according to URL format rfc3986.

String encoded = new URLCodec().encode(str);
String decoded = new URLCodec().decode(str);

If you are already using Spring, you can also opt to use its UriUtils class as well.

Mutex is basically mutual exclusion. Only one thread can acquire the resource at once. When one thread acquires the resource, no other thread is allowed to acquire the resource until the thread owning the resource releases. All threads waiting for acquiring resource would be blocked.

Semaphore is used to control the number of threads executing. There will be fixed set of resources. The resource count will gets decremented every time when a thread owns the same. When the semaphore count reaches 0 then no other threads are allowed to acquire the resource. The threads get blocked till other threads owning resource releases.

In short, the main difference is how many threads are allowed to acquire the resource at once ?

• Mutex --its ONE.
• Semaphore -- its DEFINED_COUNT, ( as many as semaphore count)

JavaScript is single-threaded, and all the time you work on a normal synchronous code-flow execution.

Good examples of the asynchronous behavior that JavaScript can have are events (user interaction, Ajax request results, etc) and timers, basically actions that might happen at any time.

I would recommend you to give a look to the following article:

• How JavaScript Timers Work

That article will help you to understand the single-threaded nature of JavaScript and how timers work internally and how asynchronous JavaScript execution works.

You can write your native or non-native query the way you want, and you can wrap JPQL query results with instances of custom result classes. Create a DTO with the same names of columns returned in query and create an all argument constructor with same sequence and names as returned by the query. Then use following way to query the database.

@Query("SELECT NEW example.CountryAndCapital(c.name, c.capital.name) FROM Country AS c")

Create DTO:

package example;

public class CountryAndCapital {
    public String countryName;
    public String capitalName;

    public CountryAndCapital(String countryName, String capitalName) {
        this.countryName = countryName;
        this.capitalName = capitalName;
    }
}

I'm surprised this question is 11yrs old and not one of the answers mentioned the #1 advantage of utf-8.

utf-8 generally works even with programs that are not utf-8 aware. That's partly what it was designed for. Other answers mention that the first 128 code points are the same as ASCII. All other code points are generated by 8bit values with the high bit set (values from 128 to 255) so that from the POV of a non-unicode aware program it just sees strings as ASCII with some extra characters.

As an example let's say you wrote a program to add line numbers that effectively does this (and to keep it simple let's assume end of line is just ASCII 13)

// pseudo code

function readLine
  if end of file
     return null
  read bytes (8bit values) into string until you hit 13 or end or file
  return string

function main
  lineNo = 1
  do {
    s = readLine
    if (s == null) break;
    print lineNo++, s
  }  

Passing a utf-8 file to this program will continue to work. Similarly, splitting on tabs, commas, parsing for ASCII quotes, or other parsing for which only ASCII values are significant all just work with utf-8 because no ASCII value appear in utf-8 except when they are actually meant to be those ASCII values

Some other answers or comments mentions that utf-32 has the advantage that you can treat each codepoint separately. This would suggest for example you could take a string like "ABCDEFGHI" and split it at every 3rd code point to make

ABC
DEF
GHI

This is false. Many code points affect other code points. For example the color selector code points that lets you choose between ?????. If you split at any arbitrary code point you'll break those.

Another example is the bidirectional code points. The following paragraph was not entered backward. It is just preceded by the 0x202E codepoint

• ?This line is not typed backward it is only displayed backward

So no, utf-32 will not let you just randomly manipulate unicode strings without a thought to their meanings. It will let you look at each codepoint with no extra code.

FYI though, utf-8 was designed so that looking at any individual byte you can find out the start of the current code point or the next code point.

If you take a arbitrary byte in utf-8 data. If it is < 128 it's the correct code point by itself. If it's >= 128 and < 192 (the top 2 bits are 10) then to find the start of the code point you need to look the preceding byte until you find a byte with a value >= 192 (the top 2 bits are 11). At that byte you've found the start of a codepoint. That byte encodes how many subsequent bytes make the code point.

If you want to find the next code point just scan until the byte < 128 or >= 192 and that's the start of the next code point.

Where xxxxxx are the bits of the code point. Concatenate the xxxx bits from the bytes to get the code point

This example doesn't work for me, for an obscure reason.

Not obscure, it's simple routing.

On OpenBSD

route add -inet 224.0.0.0/4 224.0.0.1

You can set the route to a dev on Linux

route add -net 224.0.0.0 netmask 240.0.0.0 dev wlp2s0

force all multicast traffic to one interface on Linux

   ifconfig wlp2s0 allmulti

tcpdump is super simple

tcpdump -n multicast

In your code you have:

while True:
  # For Python 3, change next line to "print(sock.recv(10240))"

Why 10240?

multicast packet size should be 1316 bytes

The most clean and modern way to use singletons in Android is just to use the Dependency Injection framework called Dagger 2. Here you have an explanation of possible scopes you can use. Singleton is one of these scopes. Dependency Injection is not that easy but you shall invest a bit of your time to understand it. It also makes testing easier.

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

This may help... use the following code and browse the folder you want to set as the working folder

setwd(choose.dir())

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.

       var request = require('request');
        request({
            url: "http://localhost:8001/xyz",
            json: true,
            headers: {
                "content-type": "application/json",
            },
            body: JSON.stringify(requestData)
        }, function(error, response, body) {
            console.log(response);
        });

use onPause() method to do what you want to do on home button.

i saw following in a book:

this.setState(state => state.someProperty.falg = false);

but i'm not sure if it's right..

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

The most reliable and technically correct approach is to transform the data in the controller. Here's a simple chunk function and usage.

function chunk(arr, size) {
  var newArr = [];
  for (var i=0; i<arr.length; i+=size) {
    newArr.push(arr.slice(i, i+size));
  }
  return newArr;
}

$scope.chunkedData = chunk(myData, 3);

Then your view would look like this:

<div class="row" ng-repeat="rows in chunkedData">
  <div class="span4" ng-repeat="item in rows">{{item}}</div>
</div>

If you have any inputs within the ng-repeat, you will probably want to unchunk/rejoin the arrays as the data is modified or on submission. Here's how this would look in a $watch, so that the data is always available in the original, merged format:

$scope.$watch('chunkedData', function(val) {
  $scope.data = [].concat.apply([], val);
}, true); // deep watch

Many people prefer to accomplish this in the view with a filter. This is possible, but should only be used for display purposes! If you add inputs within this filtered view, it will cause problems that can be solved, but are not pretty or reliable.

The problem with this filter is that it returns new nested arrays each time. Angular is watching the return value from the filter. The first time the filter runs, Angular knows the value, then runs it again to ensure it is done changing. If both values are the same, the cycle is ended. If not, the filter will fire again and again until they are the same, or Angular realizes an infinite digest loop is occurring and shuts down. Because new nested arrays/objects were not previously tracked by Angular, it always sees the return value as different from the previous. To fix these "unstable" filters, you must wrap the filter in a memoize function. lodash has a memoize function and the latest version of lodash also includes a chunk function, so we can create this filter very simply using npm modules and compiling the script with browserify or webpack.

Remember: display only! Filter in the controller if you're using inputs!

Install lodash:

npm install lodash-node

Create the filter:

var chunk = require('lodash-node/modern/array/chunk');
var memoize = require('lodash-node/modern/function/memoize');

angular.module('myModule', [])
.filter('chunk', function() {
  return memoize(chunk);
});

And here's a sample with this filter:

<div ng-repeat="row in ['a','b','c','d','e','f'] | chunk:3">
  <div class="column" ng-repeat="item in row">
    {{($parent.$index*row.length)+$index+1}}. {{item}}
  </div>
</div>

Order items vertically

1  4
2  5
3  6

Regarding vertical columns (list top to bottom) rather than horizontal (left to right), the exact implementation depends on the desired semantics. Lists that divide up unevenly can be distributed different ways. Here's one way:

<div ng-repeat="row in columns">
  <div class="column" ng-repeat="item in row">
    {{item}}
  </div>
</div>

var data = ['a','b','c','d','e','f','g'];
$scope.columns = columnize(data, 3);
function columnize(input, cols) {
  var arr = [];
  for(i = 0; i < input.length; i++) {
    var colIdx = i % cols;
    arr[colIdx] = arr[colIdx] || [];
    arr[colIdx].push(input[i]);
  }
  return arr;
}

However, the most direct and just plainly simple way to get columns is to use CSS columns:

.columns {
  columns: 3;
}

<div class="columns">
  <div ng-repeat="item in ['a','b','c','d','e','f','g']">
    {{item}}
  </div>
</div>

    public int getMin(int[] values){
        int ret = values[0];
        for(int i = 1; i < values.length; i++)
            ret = Math.min(ret,values[i]);
        return ret;
    }

If you installed the system image and still get this error, it might be that the Android SDK manager did not put the files in the right folder for the AVD manager. See an answer to Stack Overflow question How to create an AVD for Android 4.0.3? (Unable to find a 'userdata.img').

Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve(), dgesv spits this kind of error when the matrix you passed as a parameter is singular.

As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)

I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

In Windows, do this in the command prompt from the repo directory:

cd .git
del index.lock

UPDATE: I have found that I don't need to do this procedure if I wait a moment after I close out the files I'm working on before I try to switch branches. I think sometimes this issue occurs due to git catching up with a slow file system. Other, more git-knowledgeable developers can chime in if they think this is correct.

the problem here is that by using the apostrophes you are setting the value being passed to be a string, when in fact, as @Shijo stated from the documentation, the function is expecting a label or list, but not a string! If the list contains each of the name of the columns beings passed for both the left and right dataframe, then each column-name must individually be within apostrophes. With what has been stated, we can understand why this is inccorect:

new_df = pd.merge(A_df, B_df,  how='left', left_on='[A_c1,c2]', right_on = '[B_c1,c2]')

And this is the correct way of using the function:

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

Http is stateless. In order to authorize you, you have to "sign" every single request you're sending to server.

Token authentication

• A request to the server is signed by a "token" - usually it means setting specific http headers, however, they can be sent in any part of the http request (POST body, etc.)

• Pros:

  • You can authorize only the requests you wish to authorize. (Cookies - even the authorization cookie are sent for every single request.)
  • Immune to XSRF (Short example of XSRF - I'll send you a link in email that will look like <img src="http://bank.com?withdraw=1000&to=myself" />, and if you're logged in via cookie authentication to bank.com, and bank.com doesn't have any means of XSRF protection, I'll withdraw money from your account simply by the fact that your browser will trigger an authorized GET request to that url.) Note there are anti forgery measure you can do with cookie-based authentication - but you have to implement those.
  • Cookies are bound to a single domain. A cookie created on the domain foo.com can't be read by the domain bar.com, while you can send tokens to any domain you like. This is especially useful for single page applications that are consuming multiple services that are requiring authorization - so I can have a web app on the domain myapp.com that can make authorized client-side requests to myservice1.com and to myservice2.com.
• Cons:
  • You have to store the token somewhere; while cookies are stored "out of the box". The locations that comes to mind are localStorage (con: the token is persisted even after you close browser window), sessionStorage (pro: the token is discarded after you close browser window, con: opening a link in a new tab will render that tab anonymous) and cookies (Pro: the token is discarded after you close the browser window. If you use a session cookie you will be authenticated when opening a link in a new tab, and you're immune to XSRF since you're ignoring the cookie for authentication, you're just using it as token storage. Con: cookies are sent out for every single request. If this cookie is not marked as https only, you're open to man in the middle attacks.)
  • It is slightly easier to do XSS attack against token based authentication (i.e. if I'm able to run an injected script on your site, I can steal your token; however, cookie based authentication is not a silver bullet either - while cookies marked as http-only can't be read by the client, the client can still make requests on your behalf that will automatically include the authorization cookie.)
  • Requests to download a file, which is supposed to work only for authorized users, requires you to use File API. The same request works out of the box for cookie-based authentication.

Cookie authentication

• A request to the server is always signed in by authorization cookie.
• Pros:
  • Cookies can be marked as "http-only" which makes them impossible to be read on the client side. This is better for XSS-attack protection.
  • Comes out of the box - you don't have to implement any code on the client side.
• Cons:
  • Bound to a single domain. (So if you have a single page application that makes requests to multiple services, you can end up doing crazy stuff like a reverse proxy.)
  • Vulnerable to XSRF. You have to implement extra measures to make your site protected against cross site request forgery.
  • Are sent out for every single request, (even for requests that don't require authentication).

Overall, I'd say tokens give you better flexibility, (since you're not bound to single domain). The downside is you have to do quite some coding by yourself.

This is my solution for your problem :

$('#startdatetime-from').datetimepicker({
language: 'en',
format: 'yyyy-MM-dd hh:mm'
}).on('dp.change', function (e) {
        var specifiedDate = new Date(e.date);
        if (specifiedDate.getMinutes() == 0)
        {
            specifiedDate.setMinutes(1);
            $(this).data('DateTimePicker').date(specifiedDate);
        }
    });

This also work for setting a default hour or both. Note that this code sample works with the useCurrent: false parameter too.

When the user pick a date, we check if the minute is 0 (hard-coded default value). In this case, we set a 1. Then, the user cannot select 0.

Use a colon:

: ${A:=hello}

The colon is a null command that does nothing and ignores its arguments. It is built into bash so a new process is not created.

I had also entered the path of MinGW complier for C++. After removing it, the error disappeared.

In MSSQL (tested on 11.0.5569) using

SELECT TOP 100 * FROM employee ORDER BY CRYPT_GEN_RANDOM(10)

is significantly faster than

SELECT TOP 100 * FROM employee ORDER BY NEWID()

Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.

Usage is simple.

string directoryPath = Path.GetDirectoryName(filePath);

say you define the static getFactorial function inside a CodeController

then this is the way you need to call a static function, because static properties and methods exists with in the class, not in the objects created using the class.

CodeController::getFactorial($index);

----------------UPDATE----------------

To best practice I think you can put this kind of functions inside a separate file so you can maintain with more easily.

to do that

create a folder inside app directory and name it as lib (you can put a name you like).

this folder to needs to be autoload to do that add app/lib to composer.json as below. and run the composer dumpautoload command.

"autoload": {
    "classmap": [
                "app/commands",
                "app/controllers",
                ............
                "app/lib"
    ]
},

then files inside lib will autoloaded.

then create a file inside lib, i name it helperFunctions.php

inside that define the function.

if ( ! function_exists('getFactorial'))
{

    /**
     * return the factorial of a number
     *
     * @param $number
     * @return string
     */
    function getFactorial($date)
    {
        $fact = 1;

        for($i = 1; $i <= $num ;$i++)
            $fact = $fact * $i;

        return $fact;

     }
}

and call it anywhere within the app as

$fatorial_value = getFactorial(225);

Parameter names are only useful to the compiler. When the compiler generates a class file, the parameter names are not included - a method's argument list only consists of the number and types of its arguments. So it would be impossible to retrieve the parameter name using reflection (as tagged in your question) - it doesn't exist anywhere.

However, if the use of reflection is not a hard requirement, you can retrieve this information directly from the source code (assuming you have it).

i Did it, just follow this tutorial. helps a lot

Update both gem and dependencies:

bundle update gem-name 

or

Update exclusively the gem:

bundle update --source gem-name

along with some nice examples of possible side-effects.

Update

As @Tim's answer says, as of Bundler 1.14 the officially-supported way to this is with bundle update --conservative gem-name.

Command EXPOSE in your Dockerfile lets you bind container's port to some port on the host machine but it doesn't do anything else. When running container, to bind ports specify -p option.

So let's say you expose port 5000. After building the image when you run the container, run docker run -p 5000:5000 name. This binds container's port 5000 to your laptop/computers port 5000 and that portforwarding lets container to receive outside requests.

This should do it.

You should reference the textarea ID and include the runat="server" attribute to the textarea

What is test123?

The JWT aud (Audience) Claim

According to RFC 7519:

The "aud" (audience) claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the "aud" claim when this claim is present, then the JWT MUST be rejected. In the general case, the "aud" value is an array of case- sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the "aud" value MAY be a single case-sensitive string containing a StringOrURI value. The interpretation of audience values is generally application specific. Use of this claim is OPTIONAL.

The Audience (aud) claim as defined by the spec is generic, and is application specific. The intended use is to identify intended recipients of the token. What a recipient means is application specific. An audience value is either a list of strings, or it can be a single string if there is only one aud claim. The creator of the token does not enforce that aud is validated correctly, the responsibility is the recipient's to determine whether the token should be used.

Whatever the value is, when a recipient is validating the JWT and it wishes to validate that the token was intended to be used for its purposes, it MUST determine what value in aud identifies itself, and the token should only validate if the recipient's declared ID is present in the aud claim. It does not matter if this is a URL or some other application specific string. For example, if my system decides to identify itself in aud with the string: api3.app.com, then it should only accept the JWT if the aud claim contains api3.app.com in its list of audience values.

Of course, recipients may choose to disregard aud, so this is only useful if a recipient would like positive validation that the token was created for it specifically.

My interpretation based on the specification is that the aud claim is useful to create purpose-built JWTs that are only valid for certain purposes. For one system, this may mean you would like a token to be valid for some features but not for others. You could issue tokens that are restricted to only a certain "audience", while still using the same keys and validation algorithm.

Since in the typical case a JWT is generated by a trusted service, and used by other trusted systems (systems which do not want to use invalid tokens), these systems simply need to coordinate the values they will be using.

Of course, aud is completely optional and can be ignored if your use case doesn't warrant it. If you don't want to restrict tokens to being used by specific audiences, or none of your systems actually will validate the aud token, then it is useless.

Example: Access vs. Refresh Tokens

One contrived (yet simple) example I can think of is perhaps we want to use JWTs for access and refresh tokens without having to implement separate encryption keys and algorithms, but simply want to ensure that access tokens will not validate as refresh tokens, or vice-versa.

By using aud, we can specify a claim of refresh for refresh tokens and a claim of access for access tokens upon creating these tokens. When a request is made to get a new access token from a refresh token, we need to validate that the refresh token was a genuine refresh token. The aud validation as described above will tell us whether the token was actually a valid refresh token by looking specifically for a claim of refresh in aud.

OAuth Client ID vs. JWT aud Claim

The OAuth Client ID is completely unrelated, and has no direct correlation to JWT aud claims. From the perspective of OAuth, the tokens are opaque objects.

The application which accepts these tokens is responsible for parsing and validating the meaning of these tokens. I don't see much value in specifying OAuth Client ID within a JWT aud claim.

You could also check the request accept content type as specified in the rfc. That way you can render by default HTML and where your client accept application/jason you can return json in your response without a template being required

I could not get it to work with alert.('close') either.

However I am using this and it works a treat! The alert will fade away after 5 seconds, and once gone, the content below it will slide up to its natural position.

window.setTimeout(function() {
    $(".alert-message").fadeTo(500, 0).slideUp(500, function(){
        $(this).remove(); 
    });
}, 5000);

In Visual Studio 2019, there is the "Go To Member" action located in Edit - Go To that is mapped by default to ALT+\. I think this was added in Visual Studio 2017.

This is what pops up which provides the desired functionality and a couple of options:

For List :

List<Integer> intList 
 = stringList.stream().map(Integer::valueOf).collect(Collectors.toList());

For Array :

int[] intArray = Arrays.stream(stringArray).mapToInt(Integer::valueOf).toArray();

Try with below code.

Like GridView in LinkButton, Label, HtmlAnchor and HtmlInputControl.

<asp:GridView ID="mainGrid" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-hover tablesorter"
    OnRowDataBound="mainGrid_RowDataBound"  EmptyDataText="No Data Found.">
    <Columns>
        <asp:TemplateField HeaderText="HeaderName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
            <ItemTemplate>
                <asp:Label runat="server" ID="lblName" Text=' <%# Eval("LabelName") %>'></asp:Label>
                <asp:LinkButton ID="btnLink" runat="server">ButtonName</asp:LinkButton>
                <a href="javascript:void(0);" id="btnAnchor" runat="server">ButtonName</a>
                <input type="hidden" runat="server" id="hdnBtnInput" value='<%#Eval("ID") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Handling RowDataBound event,

protected void mainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lblName = (Label)e.Row.FindControl("lblName");
        LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
        HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
        HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
    }
}

Let me offer a more extensive answer considering things that you haven't mentioned as yet but will find useful.

For your current problem the answer is

$("div[id^='editDialog']");

The caret (^) is taken from regular expressions and means starts with.

Solution 1

// Select elems where 'attribute' ends with 'Dialog'
$("[attribute$='Dialog']"); 

// Selects all divs where attribute is NOT equal to value    
$("div[attribute!='value']"); 

// Select all elements that have an attribute whose value is like
$("[attribute*='value']"); 

// Select all elements that have an attribute whose value has the word foobar
$("[attribute~='foobar']"); 

// Select all elements that have an attribute whose value starts with 'foo' and ends
//  with 'bar'
$("[attribute^='foo'][attribute$='bar']");

attribute in the code above can be changed to any attribute that an element may have, such as href, name, id or src.

Solution 2

Use classes

// Matches all items that have the class 'classname'
$(".className");

// Matches all divs that have the class 'classname'
$("div.className");

Solution 3

List them (also noted in previous answers)

$("#id1,#id2,#id3");

Solution 4

For when you improve, regular expression (Never actually used these, solution one has always been sufficient, but you never know!

// Matches all elements whose id takes the form editDialog-{one_or_more_integers}
$('div').filter(function () {this.id.match(/editDialog\-\d+/)});

To grant permissions to all of the existing tables in the schema use:

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA <schema> TO <role>

To specify default permissions that will be applied to future tables use:

ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> 
  GRANT <privileges> ON TABLES TO <role>;

e.g.

ALTER DEFAULT PRIVILEGES IN SCHEMA public 
  GRANT SELECT, INSERT, UPDATE, DELETE ON TABLES TO admin;

If you use SERIAL or BIGSERIAL columns then you will probably want to do the same for SEQUENCES, or else your INSERT will fail (Postgres 10's IDENTITY doesn't suffer from that problem, and is recommended over the SERIAL types), i.e.

ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> GRANT ALL ON SEQUENCES TO <role>;

See also my answer to PostgreSQL Permissions for Web App for more details and a reusable script.

Ref:

GRANT

ALTER DEFAULT PRIVILEGES

This will do the trick for you:

foreach (int indexChecked in checkedListBox1.CheckedIndices)
{
    string itemtxt = checkedListBox11.Items[indexChecked];
}

It will return whatever string value is in the checkedlistbox items.

You may test if a string is convertible to integer by using boost::lexical_cast. If it throws bad_lexical_cast exception then string could not be converted, otherwise it can.

See example of such a test program below:

#include <boost/lexical_cast.hpp>
#include <iostream>

int main(int, char** argv)
{
        try
        {
                int x = boost::lexical_cast<int>(argv[1]);
                std::cout << x << " YES\n";
        }
        catch (boost::bad_lexical_cast const &)
        {
                std:: cout << "NO\n";
        }
        return 0;
}

Sample execution:

# ./a.out 12
12 YES
# ./a.out 12/3
NO

Try the following:

with open('data.txt', 'r') as myfile:
    data = myfile.read()

    sentences = data.split('\\n')
    for sentence in sentences:
        print(sentence)

Caution: It does not remove the \n. It is just for viewing the text as if there were no \n

Here is what I came up with and this is with not much lines of code

function show_files($start) {
    $contents = scandir($start);
    array_splice($contents, 0,2);
    echo "<ul>";
    foreach ( $contents as $item ) {
        if ( is_dir("$start/$item") && (substr($item, 0,1) != '.') ) {
            echo "<li>$item</li>";
            show_files("$start/$item");
        } else {
            echo "<li>$item</li>";
        }
    }
    echo "</ul>";
}

show_files('./');

It outputs something like

..idea
.add.php
.add_task.php
.helpers
 .countries.php
.mysqli_connect.php
.sort.php
.test.js
.test.php
.view_tasks.php

** The dots are the dots of unoordered list.

Hope this helps.

In [5]: set(df.Col1).union(set(df.Col2))
Out[5]: {'Bill', 'Bob', 'Joe', 'Mary', 'Steve'}

Or:

set(df.Col1) | set(df.Col2)

You have to define which type of exception you want to catch. So write except Exception, e: instead of except, e: for a general exception (that will be logged anyway).

Other possibility is to write your whole try/except code this way:

try:
    with open(filepath,'rb') as f:
        con.storbinary('STOR '+ filepath, f)
    logger.info('File successfully uploaded to '+ FTPADDR)
except Exception, e: # work on python 2.x
    logger.error('Failed to upload to ftp: '+ str(e))

in Python 3.x and modern versions of Python 2.x use except Exception as e instead of except Exception, e:

try:
    with open(filepath,'rb') as f:
        con.storbinary('STOR '+ filepath, f)
    logger.info('File successfully uploaded to '+ FTPADDR)
except Exception as e: # work on python 3.x
    logger.error('Failed to upload to ftp: '+ str(e))

If you are in a MySQL shell, exit it by typing exit, which will return you to the command prompt.

Now start MySQL by using exactly the following command:

sudo mysql -u root -p

If your username is something other than root, replace 'root' in the above command with your username:

sudo mysql -u <your-user-name> -p

It will then ask you the MySQL account/password, and your MySQL won't show any access privilege issue then on.

l = [1, 2, 3, 4, 5]
del l[0:3] # Here 3 specifies the number of items to be deleted.

This is the code if you want to delete a number of items from the list. You might as well skip the zero before the colon. It does not have that importance. This might do as well.

l = [1, 2, 3, 4, 5]
del l[:3] # Here 3 specifies the number of items to be deleted.

Go to that directory/folder and then click on the setting. In the section of "Repository name" simply rename it.

So I run into this a lot because I keep cp aliased to cp -iv, and I found a neat trick. It turns out that while -i and -n both cancel previous overwrite directives, -f does not. However, if you use -nf it adds the ability to clear the -i. So:

cp -f /foo/* /bar  <-- Prompt
cp -nf /foo/* /bar <-- No Prompt

Pretty neat huh? /necropost

Because one moderator deleted my detailed image-supported answer on this question, just because I copied and pasted from another question, I am forced to put a less detailed answer and I will link the original answer if you want a more visual way to see the solution.

For Visual Studio 2019 and Visual Studio 2017 Users
For People who are missing this old feature in VS2019 (or maybe VS2017) from the old versions of Visual Studio

This feature still available, but it is NOT available by default, you have to install it separately.

1. Open VS 2019 go to Tools -> Get Tools and Features
2. Select the Individual components tab and search for Class Designer
3. Select this Component and Install it, After finish installing this component (you may need to restart visual studio)
4. Right-click on the project and select Add -> Add New Item
5. Search for 'class' word and NOW you can see Class Diagram component

see this answer also to see an image associated

Update to create a class-diagram for the whole project
I received a downvote because I did not mention how to generate a diagram for the whole project, here is how to do it (after applying the previous steps)

1. Add class diagram to the project
2. if the option Preview Selected Items is enabled in the solution explorer, disabled it temporarily, you can re-enable it later

3. open the class diagram that you created in step 2 (by double-clicking on it)
4. drag-and-drop the project from the solution explorer to the class diagram

you could be shocked by the results to the point that you can change your mind and remove your downvote (please do NOT upvote, it is enough to remove your downvote)

I have once written a little SQL*Plus script that uses dbms_sql and dbms_output to create a csv (actually an ssv). You can find it on my githup repository.

Slice notation a[start_index:end_index:step]

return a[::2]

where start_index defaults to 0 and end_index defaults to the len(a).

For Eclipse Mars the following worked

1. In Eclipse select Help - Install New Software.
2. Search for "EE". Got two hits and it what obvious which to use.
3. Let IDE restart.

Try a javascript pure:

Library JS:

appendHtml = function(element, html) {
    var div = document.createElement('div');
    div.innerHTML = html;
    while (div.children.length > 0) {
        element.appendChild(div.children[0]);
    }
}

Type: appendHtml(document.head, '<link rel="stylesheet" type="text/css" href="http://example.com/example.css"/>');

or jQuery:

$('head').append($('<link rel="stylesheet" type="text/css" />').attr('href', 'http://example.com/example.css'));

for the sake of completeness, you could use:

(DT_STR,8, 1252) (YEAR(GetDate()) * 10000 + MONTH(GetDate()) * 100 + DAY(GetDate()))

for YYYYMMDD or

RIGHT("000000" + (DT_STR,8, 1252) (DAY(GetDate()) * 1000000 + MONTH(GetDate()) * 10000 + YEAR(GetDate())), 8)

for DDMMYYYY (without hyphens). If you want / need the date as integer (e.g. for _key-columns in DWHs), just remove the DT_STR / RIGTH function and do just the math.

I'm surprised that I didn't see any mention of Java's Executor framework for this question's answers. One of the main selling points of the Executor framework is so that you don't have do deal with low level threads. Instead, you're dealing with the higher level of abstraction of ExecutorServices. So, instead of manually starting a thread, just execute the executor that wraps a Runnable. Using the single thread executor, the Runnable instance you create will internally be wrapped and executed as a thread.

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
// ...

ExecutorService threadExecutor = Executors.newSingleThreadExecutor();
try {
  threadExecutor.execute(
    new Runnable() {
      @Override
      public void run() {
        System.out.println("blah");
      }
    }
  );
} finally {
    threadExecutor.shutdownNow();
}

For convenience, see the code on JDoodle.

The answers are outdated. You simply have to conda install pip and git. Then you can use pip normally:

1. Activate your conda environment source activate myenv

2. conda install git pip

3. pip install git+git://github.com/scrappy/scrappy@master

Since you are using this for configuration, your best bet is apache commons-configuration. For simple files it's way easier to use than "raw" XML parsers.

See the XML how-to

Do a import os and then use os.sep

The short answer is that the --dbpath parameter in MongoDB will allow you to control what directory MongoDB reads and writes it's data from.

mongod --dbpath /usr/local/mongodb-data

Would start mongodb and put the files in /usr/local/mongodb-data.

Depending on your distribution and MongoDB installation, you can also configure the mongod.conf file to do this automatically:

# Store data in /usr/local/var/mongodb instead of the default /data/db
dbpath = /usr/local/var/mongodb

The official 10gen Linux packages (Ubuntu/Debian or CentOS/Fedora) ship with a basic configuration file which is placed in /etc/mongodb.conf, and the MongoDB service reads this when it starts up. You could make your change here.

In case you have only one controller and you want to access every action on root you can skip controller name like this

routes.MapRoute(
        "Default", 
        "{action}/{id}", 
        new { controller = "Home", action = "Index", 
        id = UrlParameter.Optional }
);

As said before, you code will not work the way it is. A solution to that would be using a callback function, but if you think it would carry you to a 'Callback hell', you can search for "Promisses".

A possible solution using a callback function:

//DECLARE  numberofDocs OUT OF FUNCTIONS
     var  numberofDocs;
     userModel.count({}, setNumberofDocuments); //this search all DOcuments in a Collection

if you want to search the number of documents based on a query, you can do this:

 userModel.count({yourQueryGoesHere}, setNumberofDocuments);

setNumberofDocuments is a separeted function :

var setNumberofDocuments = function(err, count){ 
        if(err) return handleError(err);

        numberofDocs = count;

      };

Now you can get the number of Documents anywhere with a getFunction:

     function getNumberofDocs(){
           return numberofDocs;
        }
 var number = getNumberofDocs();

In addition , you use this asynchronous function inside a synchronous one by using a callback, example:

function calculateNumberOfDoc(someParameter, setNumberofDocuments){

       userModel.count({}, setNumberofDocuments); //this search all DOcuments in a Collection

       setNumberofDocuments(true);


} 

Hope it can help others. :)

You can create a batch by PreparedStatement#addBatch() and execute it by PreparedStatement#executeBatch().

Here's a kickoff example:

public void save(List<Entity> entities) throws SQLException {
    try (
        Connection connection = database.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL_INSERT);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setString(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

It's executed every 1000 items because some JDBC drivers and/or DBs may have a limitation on batch length.

Below is an adaptation of previous code for using under PyQt5 and Matplotlib 2.0. There are a number of small changes: structure of PyQt submodules, other submodule from matplotlib, deprecated method has been replaced...

import sys
from PyQt5.QtWidgets import QDialog, QApplication, QPushButton, QVBoxLayout

from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt5agg import NavigationToolbar2QT as NavigationToolbar
import matplotlib.pyplot as plt

import random

class Window(QDialog):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        # a figure instance to plot on
        self.figure = plt.figure()

        # this is the Canvas Widget that displays the `figure`
        # it takes the `figure` instance as a parameter to __init__
        self.canvas = FigureCanvas(self.figure)

        # this is the Navigation widget
        # it takes the Canvas widget and a parent
        self.toolbar = NavigationToolbar(self.canvas, self)

        # Just some button connected to `plot` method
        self.button = QPushButton('Plot')
        self.button.clicked.connect(self.plot)

        # set the layout
        layout = QVBoxLayout()
        layout.addWidget(self.toolbar)
        layout.addWidget(self.canvas)
        layout.addWidget(self.button)
        self.setLayout(layout)

    def plot(self):
        ''' plot some random stuff '''
        # random data
        data = [random.random() for i in range(10)]

        # instead of ax.hold(False)
        self.figure.clear()

        # create an axis
        ax = self.figure.add_subplot(111)

        # discards the old graph
        # ax.hold(False) # deprecated, see above

        # plot data
        ax.plot(data, '*-')

        # refresh canvas
        self.canvas.draw()

if __name__ == '__main__':
    app = QApplication(sys.argv)

    main = Window()
    main.show()

    sys.exit(app.exec_())

You will need to convert your response to json before you can access response.body

From the docs

fetch(url)
  .then(response => response.json())
  .then(json => {
    console.log('parsed json', json) // access json.body here
  })

As a slight (but related) asside, if you use a javascript library such as jquery (v1.3) to do your dom manipulation you can make use of live events whereby you set up a handler like:

 $("#myspan").live("click", function(){
  alert('hi');
});

and it will be applied to that selector at all times during any kind of jquery manipulation. For live events see: docs.jquery.com/events/live for jquery manipulation see: docs.jquery.com/manipulation

Surprised no one mentioned xml_parse_into_struct:

$simple = "<para><note>simple note</note></para>";
$p = xml_parser_create();
xml_parse_into_struct($p, $simple, $vals, $index);
xml_parser_free($p);
echo "Index array\n";
print_r($index);
echo "\nVals array\n";
print_r($vals);

I was doing something for a list which is a set of strings and you want to remove all lines that have a certain substring you can do this

import re
def RemoveInList(sub,LinSplitUnOr):
    indices = [i for i, x in enumerate(LinSplitUnOr) if re.search(sub, x)]
    A = [i for j, i in enumerate(LinSplitUnOr) if j not in indices]
    return A

where sub is a patter that you do not wish to have in a list of lines LinSplitUnOr

for example

A=['Apple.good','Orange.good','Pear.bad','Pear.good','Banana.bad','Potato.bad']
sub = 'good'
A=RemoveInList(sub,A)

Then A will be

What you're trying to do is to monitor the property of attribute in directive. You can watch the property of attribute changes using $observe() as follows:

angular.module('myApp').directive('conversation', function() {
  return {
    restrict: 'E',
    replace: true,
    compile: function(tElement, attr) {
      attr.$observe('typeId', function(data) {
            console.log("Updated data ", data);
      }, true);

    }
  };
});

Keep in mind that I used the 'compile' function in the directive here because you haven't mentioned if you have any models and whether this is performance sensitive.

If you have models, you need to change the 'compile' function to 'link' or use 'controller' and to monitor the property of a model changes, you should use $watch(), and take of the angular {{}} brackets from the property, example:

<conversation style="height:300px" type="convo" type-id="some_prop"></conversation>

And in the directive:

angular.module('myApp').directive('conversation', function() {
  return {
    scope: {
      typeId: '=',
    },
    link: function(scope, elm, attr) {

      scope.$watch('typeId', function(newValue, oldValue) {
          if (newValue !== oldValue) {
            // You actions here
            console.log("I got the new value! ", newValue);
          }
      }, true);

    }
  };
});

I'm using opencv which relies on binaries etc so I have scripts where every other line has this silly error. Python is a dynamic language so such occasions shouldn't be considered errors.

I removed these errors altogether by going to:

Window -> Preferences -> PyDev -> Editor -> Code Analysis -> Undefined -> Undefined Variable From Import -> Ignore

And that's that.

It may also be, Window -> Preferences -> PyDev -> Editor -> Code Analysis -> Imports -> Import not found -> Ignore

I used a slight variant of Reuban's answer, which proved to be more helpful in certain circumstances, especially with high resolution devices.

final View activityRootView = findViewById(android.R.id.content);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(
        new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int heightView = activityRootView.getHeight();
                int widthView = activityRootView.getWidth();
                if (1.0 * widthView / heightView > 3) {
                    //Make changes for Keyboard not visible
                } else {
                    //Make changes for keyboard visible
                }
            }
        });

For this example we take it for granted that varcharcol doesn't contain '' and have no empty cell against this column

select * from some_table where varcharCol = ''
select * from some_table where varcharCol like ''

The first one results in 0 row output while the second one shows the whole list. = is strictly-match case while like acts like a filter. if filter has no criteria, every data is valid.

like - by the virtue of its purpose works a little slower and is intended for use with varchar and similar data.

if (drMyRow.Table.Columns["ColNameToCheck"] != null)
{
   doSomethingUseful;
{
else { return; }

Although the DataRow does not have a Columns property, it does have a Table that the column can be checked for.

 $('mainCheckBox').click(function(){
    if($(this).prop('checked')){
        $('Id or Class of checkbox').prop('checked', true);
    }else{
        $('Id or Class of checkbox').prop('checked', false);
    }
});

This technique is usually used for multiple axis in a figure. In this context it is often required to have a colorbar that corresponds in size with the result from imshow. This can be achieved easily with the axes grid tool kit:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
divider = make_axes_locatable(ax)
cax = divider.append_axes('right', size='5%', pad=0.05)

im = ax.imshow(data, cmap='bone')

fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

All OS comes with a default version of python and it resides in /usr/bin. All scripts that come with the OS (e.g. yum) point this version of python residing in /usr/bin. When you want to install a new version of python you do not want to break the existing scripts which may not work with new version of python.

The right way of doing this is to install the python as an alternate version.

e.g.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure --prefix=/usr/local/
make && make altinstall

Now by doing this the existing scripts like yum still work with /usr/bin/python. and your default python version would be the one installed in /usr/local/bin. i.e. when you type python you would get 2.7.3

This happens because. $PATH variable has /usr/local/bin before usr/bin.

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

If python2.7 still does not take effect as the default python version you would need to do

export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"

For making addition of foreign key constraint in laravel, the following worked for me:

1. Create the column to be foreign key as follows:

   $table->integer('column_name')->unsigned();

2. Adding the constraint line immediately after (1) i.e.

   $table->integer('column_name')->unsigned();
   $table->foreign('column_name')->references('pk_of_other_table')->on('other_table');

This error would suggest that User::where('email', '=', $userEmail)->first() is returning null, rather than a problem with updating your model.

Check that you actually have a User before attempting to change properties on it, or use the firstOrFail() method.

$UpdateDetails = User::where('email', $userEmail)->first();

if (is_null($UpdateDetails)) {
    return false;
}

or using the firstOrFail() method, theres no need to check if the user is null because this throws an exception (ModelNotFoundException) when a model is not found, which you can catch using App::error() http://laravel.com/docs/4.2/errors#handling-errors

$UpdateDetails = User::where('email', $userEmail)->firstOrFail();

In addition to Daniel Howard's answer, here is what new does (or at least seems to do):

function New(func) {
    var res = {};
    if (func.prototype !== null) {
        res.__proto__ = func.prototype;
    }
    var ret = func.apply(res, Array.prototype.slice.call(arguments, 1));
    if ((typeof ret === "object" || typeof ret === "function") && ret !== null) {
        return ret;
    }
    return res;
}

While

var obj = New(A, 1, 2);

is equivalent to

var obj = new A(1, 2);

You could do something with APIs.

Private Const SW_SHOW = 5

The advantage of IEnumerable is deferred execution (usually with databases). The query will not get executed until you actually loop through the data. It's a query waiting until it's needed (aka lazy loading).

If you call ToList, the query will be executed, or "materialized" as I like to say.

There are pros and cons to both. If you call ToList, you may remove some mystery as to when the query gets executed. If you stick to IEnumerable, you get the advantage that the program doesn't do any work until it's actually required.

Unfortunately using an XML drawable and overriding the background means you have to explicitly set the colour instead of being able to use the app style colours.

Rather than hardcode the button colours for every behaviour I opted to hardcode the corner radius, which feels marginally less hacky and retains all the default button behaviour (changing colour when it's pressed and other visual effects) and uses the app style colours by default:

1. Set android:layout_height and android:layout_width to the same value

2. Set app:cornerRadius to half of the height/width

   (It actually appears that anything greater than or equal to half of the height/width works, so to avoid having to change the radius every time you update the height/width, you could instead set it to a very high value such as 1000dp, the risk being it could break if this behaviour ever changes.)

3. Set android:insetBottom and android:insetTop to 0dp to get a perfect circle

For example:

<Button
    android:insetBottom="0dp"
    android:insetTop="0dp"
    android:layout_height="150dp"
    android:layout_width="150dp"
    app:cornerRadius="75dp"
    />

You can call java myProg arg1 arg2 ... :

public static void main (String args[]) {
    BufferedReader in = new BufferedReader(new FileReader(args[0]));
}

Working and just tested solution for Swift 3 with Xcode 8.3.3:

self.view.layoutIfNeeded()
self.calendarViewHeight.constant = 56.0

UIView.animate(withDuration: 0.5, delay: 0.0, options: UIViewAnimationOptions.curveEaseIn, animations: {
        self.view.layoutIfNeeded()
    }, completion: nil)

Just keep in mind that self.calendarViewHeight is a constraint referred to a customView (CalendarView). I called the .layoutIfNeeded() on self.view and NOT on self.calendarView

Hope this help.

for more advanced python editing consider installing the simplefold vim plugin. it allows you do advanced code folding using regular expressions. i use it to fold my class and method definitions for faster editing.

You can try: a=[0,1,2,3,4,5,6,7,8,9];

[abs(x[1]-x[0]) for x in zip(a[1:],a[:-1])]

You are applying the formatting to the workbook that has the code, not the added workbook. You'll want to get in the habit of fully qualifying sheet and range references. The code below does that and works for me in Excel 2010:

Sub test()
Dim wb As Excel.Workbook
Set wb = Workbooks.Add
With wb.Sheets(1)
    .Range("A1") = "Acctdate"
    .Range("B1") = "Ledger"
    .Range("C1") = "CY"
    .Range("D1") = "BusinessUnit"
    .Range("E1") = "OperatingUnit"
    .Range("F1") = "LOB"
    .Range("G1") = "Account"
    .Range("H1") = "TreatyCode"
    .Range("I1") = "Amount"
    .Range("J1") = "TransactionCurrency"
    .Range("K1") = "USDEquivalentAmount"
    .Range("L1") = "KeyCol"
    .Range("A2", "A50000").Value = Me.TextBox3.Value
    .Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"
End With
End Sub

You can also use the Builder pattern if you want to show that some parameters are mandatory.

    public enum EnumSingleton {

    INSTANCE;

    private String name; // Mandatory
    private Double age = null; // Not Mandatory

    private void build(SingletonBuilder builder) {
        this.name = builder.name;
        this.age = builder.age;
    }

    // Static getter
    public static EnumSingleton getSingleton() {
        return INSTANCE;
    }

    public void print() {
        System.out.println("Name "+name + ", age: "+age);
    }


    public static class SingletonBuilder {

        private final String name; // Mandatory
        private Double age = null; // Not Mandatory

        private SingletonBuilder(){
          name = null;
        }

        SingletonBuilder(String name) {
            this.name = name;
        }

        public SingletonBuilder age(double age) {
            this.age = age;
            return this;
        }

        public void build(){
            EnumSingleton.INSTANCE.build(this);
        }

    }


}

Then you could create/instantiate/parametrized it as follow:

public static void main(String[] args) {
    new EnumSingleton.SingletonBuilder("nico").age(41).build();
    EnumSingleton.getSingleton().print();
}

It would be best to use:

var pattern = /^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,20}$/;

This allows domains such as: whatever.info (4 letters at the end)

Also to test, using

pattern.test("[email protected]")

returns true if it works

The value of the certificate comes mostly from the trust of the internet users in the issuer of the certificate. To that end, Verisign is tough to beat. A certificate says to the client that you are who you say you are, and the issuer has verified that to be true.

You can get a free SSL certificate signed, for example, by StartSSL. This is an improvement on self-signed certificates, because your end-users would stop getting warning pop-ups informing them of a suspicious certificate on your end. However, the browser bar is not going to turn green when communicating with your site over https, so this solution is not ideal.

The cheapest SSL certificate that turns the bar green will cost you a few hundred dollars, and you would need to go through a process of proving the identity of your company to the issuer of the certificate by submitting relevant documents.

This answer is based on the title and not the specific case in the original post.

I had an insert procedure that kept throwing this annoying error, and even though the error says, "procedure....has too many arguments specified," the fact is that the procedure did NOT have enough arguments.

The table had an incremental id column, and since it is incremental, I did not bother to add it as a variable/argument to the proc, but it turned out that it is needed, so I added it as @Id and viola like they say...it works.

Strings are immutable, meaning you can't change a character. Instead, you create new strings.

What you are asking can be done several ways. The most appropriate solution will vary depending on the nature of the changes you are making to the original string. Are you changing only one character? Do you need to insert/delete/append?

Here are a couple ways to create a new string from an existing string, but having a different first character:

str = 'M' + str.Remove(0, 1);

str = 'M' + str.Substring(1);

Above, the new string is assigned to the original variable, str.

I'd like to add that the answers from others demonstrating StringBuilder are also very appropriate. I wouldn't instantiate a StringBuilder to change one character, but if many changes are needed StringBuilder is a better solution than my examples which create a temporary new string in the process. StringBuilder provides a mutable object that allows many changes and/or append operations. Once you are done making changes, an immutable string is created from the StringBuilder with the .ToString() method. You can continue to make changes on the StringBuilder object and create more new strings, as needed, using .ToString().

For whatever reason $('.panel-collapse').collapse({'toggle': true, 'parent': '#accordion'}); only seems to work the first time and it only works to expand the collapsible. (I tried to start with a expanded collapsible and it wouldn't collapse.)

It could just be something that runs once the first time you initialize collapse with those parameters.

You will have more luck using the show and hide methods.

Here is an example:

$(function() {

  var $active = true;

  $('.panel-title > a').click(function(e) {
    e.preventDefault();
  });

  $('.collapse-init').on('click', function() {
    if(!$active) {
      $active = true;
      $('.panel-title > a').attr('data-toggle', 'collapse');
      $('.panel-collapse').collapse('hide');
      $(this).html('Click to disable accordion behavior');
    } else {
      $active = false;
      $('.panel-collapse').collapse('show');
      $('.panel-title > a').attr('data-toggle','');
      $(this).html('Click to enable accordion behavior');
    }
  });

});

Update

Granted KyleMit seems to have a way better handle on this then me. I'm impressed with his answer and understanding.

I don't understand what's going on or why the show seemed to be toggling in some places.

But After messing around for a while.. Finally came with the following solution:

$(function() {
  var transition = false;
  var $active = true;

  $('.panel-title > a').click(function(e) {
    e.preventDefault();
  });

  $('#accordion').on('show.bs.collapse',function(){
    if($active){
        $('#accordion .in').collapse('hide');
    }
  });

  $('#accordion').on('hidden.bs.collapse',function(){
    if(transition){
        transition = false;
        $('.panel-collapse').collapse('show');
    }
  });

  $('.collapse-init').on('click', function() {
    $('.collapse-init').prop('disabled','true');
    if(!$active) {
      $active = true;
      $('.panel-title > a').attr('data-toggle', 'collapse');
      $('.panel-collapse').collapse('hide');
      $(this).html('Click to disable accordion behavior');
    } else {
      $active = false;
      if($('.panel-collapse.in').length){
        transition = true;
        $('.panel-collapse.in').collapse('hide');       
      }
      else{
        $('.panel-collapse').collapse('show');
      }
      $('.panel-title > a').attr('data-toggle','');
      $(this).html('Click to enable accordion behavior');
    }
    setTimeout(function(){
        $('.collapse-init').prop('disabled','');
    },800);
  });
});

I made this:

function repeat(func, times) {
    for (var i=0; i<times; i++) {
        func(i);
    }
}

Usage:

repeat(function(i) {
    console.log("Hello, World! - "+i);
}, 5)

/*
Returns:
Hello, World! - 0
Hello, World! - 1
Hello, World! - 2
Hello, World! - 3
Hello, World! - 4
*/

The i variable returns the amount of times it has looped - useful if you need to preload an x amount of images.

Add

<form target="_blank" ...></form>

or

form.setAttribute("target", "_blank");

You don't need JDK to run Java based programs. JDK is for development which stands for Java Development Kit.

You need JRE which should be there in Mac.

Try: java -jar Myjar_file.jar

EDIT: According to this article, for Mac OS 10

The Java runtime is no longer installed automatically as part of the OS installation.

Then, you need to install JRE to your machine.

A sample - write multiple rows with boolean column (using example above by GaretJax and Eran?).

import csv
RESULT = [['IsBerry','FruitName'],
          [False,'apple'],
          [True, 'cherry'],
          [False,'orange'],
          [False,'pineapple'],
          [True, 'strawberry']]
with open("../datasets/dashdb.csv", 'wb') as resultFile:
    wr = csv.writer(resultFile, dialect='excel')
    wr.writerows(RESULT)

Result:

df_data_4 = pd.read_csv('../datasets/dashdb.csv')
df_data_4.head()

Output:

   IsBerry  FruitName
   0    False   apple
   1    True    cherry
   2    False   orange
   3    False   pineapple
   4    True    strawberry

I am on Windows 10, I had the problem with a new fresh installation of Anaconda on python 3.7.4, this post on github solved my problem:

For the people struggling in Kotlin, it works like this:

lateinit var runnable: Runnable //global variable

 runOnUiThread { //Lambda
            runnable = Runnable {

                //do something here

                runDelayedHandler(5000)
            }
        }

        runnable.run()

 //you need to keep the handler outside the runnable body to work in kotlin
 fun runDelayedHandler(timeToWait: Long) {

        //Keep it running
        val handler = Handler()
        handler.postDelayed(runnable, timeToWait)
    }

I use Consolas for everything, including Notepad++, SQL Studio, Eclipse, etc. I wish there was a Mac version. Also, if you notice, the text area field on Stack Overflow uses Consolas, so we have some other fans out there as well :p

The C# compiler infers the true type of the var variable at compile time. There's no difference in the generated IL.

Possible redundant answer but since I found it useful, here it is:

While a FreeBSD root (i.e. using csh) I wanted to copy my whole root filesystem to /mnt but without /usr and (obviously) /mnt. This is what worked (I am at /):

tar --exclude ./usr --exclude ./mnt --create --file - . (cd /mnt && tar xvd -)

My whole point is that it was necessary (by putting the ./) to specify to tar that the excluded directories where part of the greater directory being copied.

I think the fastest solution is

select * from table where rand() <= .3

Here is why I think this should do the job.

• It will create a random number for each row. The number is between 0 and 1
• It evaluates whether to display that row if the number generated is between 0 and .3 (30%).

This assumes that rand() is generating numbers in a uniform distribution. It is the quickest way to do this.

I saw that someone had recommended that solution and they got shot down without proof.. here is what I would say to that -

• This is O(n) but no sorting is required so it is faster than the O(n lg n)

• mysql is very capable of generating random numbers for each row. Try this -

  select rand() from INFORMATION_SCHEMA.TABLES limit 10;

Since the database in question is mySQL, this is the right solution.

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
        MyCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

        cell.poster.image = nil; // or cell.poster.image = [UIImage imageNamed:@"placeholder.png"];

        NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://myurl.com/%@.jpg", self.myJson[indexPath.row][@"movieId"]]];

        NSURLSessionTask *task = [[NSURLSession sharedSession] dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
            if (data) {
                UIImage *image = [UIImage imageWithData:data];
                if (image) {
                    dispatch_async(dispatch_get_main_queue(), ^{
                        MyCell *updateCell = (id)[tableView cellForRowAtIndexPath:indexPath];
                        if (updateCell)
                            updateCell.poster.image = image;
                    });
                }
            }

1.First create a xml file name shadow.xml in "drawable" folder and copy the below code into it.

 <?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item>
            <shape android:shape="rectangle">
                <solid android:color="#CABBBBBB" />
                <corners android:radius="10dp" />
            </shape>
        </item>

        <item
            android:bottom="6dp"
            android:left="0dp"
            android:right="6dp"
            android:top="0dp">
            <shape android:shape="rectangle">
                <solid android:color="@android:color/white" />
                <corners android:radius="4dp" />
            </shape>
        </item>
    </layer-list>

Then add the the layer-list as background in your LinearLayout.

<LinearLayout
        android:id="@+id/header_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

If you are using six, you can try this, by which utilizing the latest Python 3 API and can run in both Python 2/3:

import six

if six.PY2:
    # FileNotFoundError is only available since Python 3.3
    FileNotFoundError = IOError
    from io import open

fname = 'index.rst'
try:
    with open(fname, "rt", encoding="utf-8") as f:
        pass
        # do_something_with_f ...
except FileNotFoundError:
    print('Oops.')

And, Python 2 support abandon is just deleting everything related to six.

It's a default font on Macs, but rare on PCs. Since it's not technically web-safe, some people may have it and some people may not. If you want to use a font like that, without using @font-face, you may want to write it out several different ways because it might not work the same for everyone.

I like using a font stack that touches on all bases like this:

font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", 
  Helvetica, Arial, "Lucida Grande", sans-serif;

This recommended font-family stack is further described in this CSS-Tricks snippet Better Helvetica which uses a font-weight: 300; as well.

You can check the CSS display property:

if ($('#car').css('display') == 'none') {
    alert('Car 2 is hidden');
}

The following (C#) code should do the trick

Uri uri = new Uri("http://www.mywebsite.com:80/pages/page1.aspx");
string requested = uri.Scheme + Uri.SchemeDelimiter + uri.Host + ":" + uri.Port;

Pandas Timestamp to datetime.datetime:

pd.Timestamp('2014-01-23 00:00:00', tz=None).to_pydatetime()

datetime.datetime to Timestamp

pd.Timestamp(datetime(2014, 1, 23))

Just running through a Visual Studio Code tutorial and came across a similiar issue.

Replace #include "stdafx.h" with #include "pch.h" which is the updated name for the precompiled headers.

'Is not possible!'

Oh yes it is ....

//------------------------------
function unloadJS(scriptName) {
  var head = document.getElementsByTagName('head').item(0);
  var js = document.getElementById(scriptName);
  js.parentNode.removeChild(js);
}


//----------------------
function unloadAllJS() {
  var jsArray = new Array();
  jsArray = document.getElementsByTagName('script');
  for (i = 0; i < jsArray.length; i++){
    if (jsArray[i].id){
      unloadJS(jsArray[i].id)
    }else{
      jsArray[i].parentNode.removeChild(jsArray[i]);
    }
  }      
}

Say for example, we want to remove all 1's from x. This is how I would go about it:

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

Now, this is a practical use of my method:

def Function(List, Unwanted):
    [List.remove(Unwanted) for Item in range(List.count(Unwanted))]
    return List
x = Function(x, 1)
print(x)

And this is my method in a single line:

[x.remove(1) for Item in range(x.count(1))]
print(x)

Both yield this as an output:

[2, 3, 2, 3, 2, 3]

Hope this helps. PS, pleas note that this was written in version 3.6.2, so you might need to adjust it for older versions.

Use this code (taken from css-tricks) that will work on all browser

overflow-wrap: break-word;
word-wrap: break-word;

-ms-word-break: break-all;
/* This is the dangerous one in WebKit, as it breaks things wherever */
word-break: break-all;
/* Instead use this non-standard one: */
word-break: break-word;

/* Adds a hyphen where the word breaks, if supported (No Blink) */
-ms-hyphens: auto;
-moz-hyphens: auto;
-webkit-hyphens: auto;
hyphens: auto;

I think there is a simpler way:

 public async Task<string> CreateSoapEnvelope()
 {
      string soapString = @"<?xml version=""1.0"" encoding=""utf-8""?>
          <soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
              <soap:Body>
                  <HelloWorld xmlns=""http://tempuri.org/"" />
              </soap:Body>
          </soap:Envelope>";

          HttpResponseMessage response = await PostXmlRequest("your_url_here", soapString);
          string content = await response.Content.ReadAsStringAsync();

      return content;
 }

 public static async Task<HttpResponseMessage> PostXmlRequest(string baseUrl, string xmlString)
 {
      using (var httpClient = new HttpClient())
      {
          var httpContent = new StringContent(xmlString, Encoding.UTF8, "text/xml");
          httpContent.Headers.Add("SOAPAction", "http://tempuri.org/HelloWorld");

          return await httpClient.PostAsync(baseUrl, httpContent);
       }
 }

You could use a :

@RequestParam(value="somvalue",required=false)

for optional params rather than a pathVariable

If your problem is like the following while using Google Chrome:

[XMLHttpRequest cannot load file. Received an invalid response. Origin 'null' is therefore not allowed access.]

Then create a batch file by following these steps:

Open notepad in Desktop.

1. Just copy and paste the followings in your currently opened notepad file:

start "chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files exit

1. Note: In the previous line, Replace the full absolute address with your location of chrome installation. [To find it...Right click your short cut of chrome.exe link or icon and Click on Properties and copy-paste the target link][Remember : start to files in one line, & exit in another line by pressing enter]
2. Save the file as fileName.bat [Very important: .bat]
3. If you want to change the file later then right-click on the .bat file and click on edit. After modifying, save the file.

This will do what? It will open Chrome.exe with file access. Now, from any location in your computer, browse your html files with Google Chrome. I hope this will solve the XMLHttpRequest problem.

Keep in mind : Just use the shortcut bat file to open Chrome when you require it. Tell me if it solves your problem. I had a similar problem and I solved it in this way. Thanks.

for mac I can tell you that first you have to check your path

by executing this command

which python or which python3

then you have to configure it in your pycharm.

pycharm-->preferences-->gear button-->add..

click on system interpreter--> then on ...

then you search where your python version is installed

once it is done then you have to configure for your project

click on edit configuration

then choose the python interpreter

You can do like this

$q  = $this->db->get()->row();

return $q->campaign_id;

Gradle can be used for many purposes - it's a much better Swiss army knife than Ant - but it's specifically focused on multi-project builds.

First of all, Gradle is a dependency programming tool which also means it's a programming tool. With Gradle you can execute any random task in your setup and Gradle will make sure all declared dependecies are properly and timely executed. Your code can be spread across many directories in any kind of layout (tree, flat, scattered, ...).

Gradle has two distinct phases: evaluation and execution. Basically, during evaluation Gradle will look for and evaluate build scripts in the directories it is supposed to look. During execution Gradle will execute tasks which have been loaded during evaluation taking into account task inter-dependencies.

On top of these dependency programming features Gradle adds project and JAR dependency features by intergration with Apache Ivy. As you know Ivy is a much more powerful and much less opinionated dependency management tool than say Maven.

Gradle detects dependencies between projects and between projects and JARs. Gradle works with Maven repositories (download and upload) like the iBiblio one or your own repositories but also supports and other kind of repository infrastructure you might have.

In multi-project builds Gradle is both adaptable and adapts to the build's structure and architecture. You don't have to adapt your structure or architecture to your build tool as would be required with Maven.

Gradle tries very hard not to get in your way, an effort Maven almost never makes. Convention is good yet so is flexibility. Gradle gives you many more features than Maven does but most importantly in many cases Gradle will offer you a painless transition path away from Maven.

This is solution without jquery.

Add Calendar and TextBox in WebForm -> Source of WebForm has this:

<asp:Calendar ID="Calendar1" runat="server" OnSelectionChanged="DateChange">
</asp:Calendar>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

Create methods in cs file of WebForm:

protected void Page_Load(object sender, EventArgs e)
    {
        TextBox1.Text = DateTime.Today.ToShortDateString()+'.';
    }

    protected void DateChange(object sender, EventArgs e)
    {
        TextBox1.Text = Calendar1.SelectedDate.ToShortDateString() + '.';
    }

Method DateChange is connected with Calendar event SelectionChanged. It looks like this: DatePicker Image
