In my case, VS 2019 on Windows 10 x64, I followed mostly what it was said in the answers but pasted rc.exe and rcdll.dll from C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x86 to C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin, which is where link.exe is.

You can use this command:

curl -X POST --header 'Content-Type: multipart/form-data' --header 'Accept: application/json' --header 'Authorization: <<Removed>>' -F file=@"/home/xxx/Desktop/customers.json"  'API_SERVER_URL' -k 

KISS answer

Difference:

START_STICKY

the system will try to re-create your service after it is killed

START_NOT_STICKY

the system will not try to re-create your service after it is killed

Standard example:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return START_STICKY;
}

Applying the DRY principle to Omar's solution, here's an HTML Helper extension:

using System.Web.Mvc;
using System.Text.RegularExpressions;

namespace System.Web.Mvc.Html {
    public static class MyHtmlHelpers {
        public static MvcHtmlString EncodedReplace(this HtmlHelper helper, string input, string pattern, string replacement) {
            return new MvcHtmlString(Regex.Replace(helper.Encode(input), pattern, replacement));
        }
    }
}

Usage (with improved regex):

@Html.EncodedReplace(Model.CommentText, "[\n\r]+", "<br />")

This also has the added benefit of putting less onus on the Razor View developer to ensure security from XSS vulnerabilities.

My concern with Jacob's solution is that rendering the line breaks with CSS breaks the HTML semantics.

Try this:

Right(RC[-1],Len(RC[-1])-InStrRev(RC[-1]," "))

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();

I wrote an article of when to use an abstract class and when to use an interface. There is a lot more of a difference between them other than "one IS-A... and one CAN-DO...". To me, those are canned answers. I mention a few reasons when to use either of them. Hope it helps.

http://codeofdoom.com/wordpress/2009/02/12/learn-this-when-to-use-an-abstract-class-and-an-interface/

The application is a server which simply runs until the system shuts down or it receives a Ctrl+C or the console window is closed.

Due to the extraordinary nature of the application, it is not feasible to "gracefully" exit. (It may be that I could code another application which would send a "server shutdown" message but that would be overkill for one application and still insufficient for certain circumstances like when the server (Actual OS) is actually shutting down.)

Because of these circumstances I added a "ConsoleCtrlHandler" where I stop my threads and clean up my COM objects etc...

Public Declare Auto Function SetConsoleCtrlHandler Lib "kernel32.dll" (ByVal Handler As HandlerRoutine, ByVal Add As Boolean) As Boolean

Public Delegate Function HandlerRoutine(ByVal CtrlType As CtrlTypes) As Boolean

Public Enum CtrlTypes
  CTRL_C_EVENT = 0
  CTRL_BREAK_EVENT
  CTRL_CLOSE_EVENT
  CTRL_LOGOFF_EVENT = 5
  CTRL_SHUTDOWN_EVENT
End Enum

Public Function ControlHandler(ByVal ctrlType As CtrlTypes) As Boolean
.
.clean up code here
.
End Function

Public Sub Main()
.
.
.
SetConsoleCtrlHandler(New HandlerRoutine(AddressOf ControlHandler), True)
.
.
End Sub

This setup seems to work out perfectly. Here is a link to some C# code for the same thing.

Source: java-implementation-of-rubys-gsub

Usage:

// Rewrite an ancient unit of length in SI units.
String result = new Rewriter("([0-9]+(\\.[0-9]+)?)[- ]?(inch(es)?)") {
    public String replacement() {
        float inches = Float.parseFloat(group(1));
        return Float.toString(2.54f * inches) + " cm";
    }
}.rewrite("a 17 inch display");
System.out.println(result);

// The "Searching and Replacing with Non-Constant Values Using a
// Regular Expression" example from the Java Almanac.
result = new Rewriter("([a-zA-Z]+[0-9]+)") {
    public String replacement() {
        return group(1).toUpperCase();
    }
}.rewrite("ab12 cd efg34");
System.out.println(result);

Implementation (redesigned):

import static java.lang.String.format;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public abstract class Rewriter {
    private Pattern pattern;
    private Matcher matcher;

    public Rewriter(String regularExpression) {
        this.pattern = Pattern.compile(regularExpression);
    }

    public String group(int i) {
        return matcher.group(i);
    }

    public abstract String replacement() throws Exception;

    public String rewrite(CharSequence original) {
        return rewrite(original, new StringBuffer(original.length())).toString();
    }

    public StringBuffer rewrite(CharSequence original, StringBuffer destination) {
        try {
            this.matcher = pattern.matcher(original);
            while (matcher.find()) {
                matcher.appendReplacement(destination, "");
                destination.append(replacement());
            }
            matcher.appendTail(destination);
            return destination;
        } catch (Exception e) {
            throw new RuntimeException("Cannot rewrite " + toString(), e);
        }
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(pattern.pattern());
        for (int i = 0; i <= matcher.groupCount(); i++)
            sb.append(format("\n\t(%s) - %s", i, group(i)));
        return sb.toString();
    }
}

Have you tried using Form.ShowDialog() instead of Form.Show()?

ShowDialog shows your window as modal, which means you cannot interact with the parent form until it closes.

It looks like the phoneGap plugin will allow you to get the device's uid.

http://docs.phonegap.com/en/3.0.0/cordova_device_device.md.html#device.uuid

Update: This is dependent on running native code. We used this solution writing javascript that was being compiled to native code for a native phone application we were creating.

Deploy your application in the IIS with the default port. Try to debug it using visual studio. It's a good practice. If you use visual studio, it will keep changing the port number most of the time. So better deploy the application in the IIS first and Open the same in visual studio and Debug it.

I find this Angular How-to: Editable Config Files from Microsoft Dev blogs being the best solution. You can configure dev build settings or prod build settings.

A nice way to achieve this "if you have an office 365 account" is to use Office 365 outlook connector integrated with Azure Logic App,

Hope this helps someone!

1. Install Xcode and Xcode Command Line Tools as mentioned.
2. Use Pillow instead, as PIL is basically dead. Pillow is a maintained fork of PIL.

https://pypi.org/project/Pillow/

pip install Pillow

If you have both Pythons installed and want to install this for Python3:

python3 -m pip install Pillow

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

INSERT INTO mt_magazine_subscription SELECT *
       FROM tbl_magazine_subscription 
       ORDER BY magazine_subscription_id ASC

Why not just use rm -rf /some/dir? That will remove the directory if it's present, otherwise do nothing. Unlike rm -r /some/dir this flavor of the command won't crash if the folder doesn't exist.

I have created a simple, lightweight class (about 260 LoC) that extends the standard android.util.Log implementation with file based logging:
Every log message is logged via android.util.Log and also written to a text file on the device.

You can find it on github:
https://github.com/volkerv/FileLog

You should use #!/usr/bin/env bash for portability: different *nixes put bash in different places, and using /usr/bin/env is a workaround to run the first bash found on the PATH. And sh is not bash.

I figured out this workaround:

>>> p = subprocess.Popen(['grep','f'],stdout=subprocess.PIPE,stdin=subprocess.PIPE)
>>> p.stdin.write(b'one\ntwo\nthree\nfour\nfive\nsix\n') #expects a bytes type object
>>> p.communicate()[0]
'four\nfive\n'
>>> p.stdin.close()

Is there a better one?

I had this problem despite:

• having a main(); and
• configuring all other projects in my solution to be static libraries.

My eventual fix was the following:

• my main() was in a namespace, so was effectively called something::main() ...removing this namespace fixed the problem.

Arrays.asList("Ryan", "Julie", "Bob");

One trick is to turn on the rewrite log. To turn it on, try this line in your apache main config or current virtual host file (not in .htaccess):

LogLevel alert rewrite:trace6

Before Apache httpd 2.4 mod_rewrite, such a per-module logging configuration did not exist yet, instead you could use the following logging settings:

RewriteEngine On
RewriteLog "/var/log/apache2/rewrite.log"
RewriteLogLevel 3

I also faced that problem and there are two ways to solve this in laravel.

1. first one is you can set the default value as null. I will show you an example:

   public function up()
   {
       Schema::create('users', function (Blueprint $table) {
           $table->increments('id');
           $table->string('name');
           $table->string('gender');
           $table->string('slug');
           $table->string('pic')->nullable();
           $table->string('email')->unique();
           $table->string('password');
           $table->rememberToken();
           $table->timestamps();
       });
   }
   

as the above example, you can set nullable() for that feature. then when you are inserting data MySQL set the default value as null.

2. second one is in your model set your input field in protected $fillable field. as example:

   protected $fillable = [
       'name', 'email', 'password', 'slug', 'gender','pic'
   ];
   

I think the second one is fine than the first one and also you can set nullable feature as well as fillable in the same time without a problem.

write this

To hide

{document.getElementById("p2").style.display="none";}

to show

{document.getElementById("p2").style.display="block";}

The <Leader> key is mapped to \ by default. So if you have a map of <Leader>t, you can execute it by default with \+t. For more detail or re-assigning it using the mapleader variable, see

:help leader

To define a mapping which uses the "mapleader" variable, the special string
"<Leader>" can be used.  It is replaced with the string value of "mapleader".
If "mapleader" is not set or empty, a backslash is used instead.  
Example:
    :map <Leader>A  oanother line <Esc>
Works like:
    :map \A  oanother line <Esc>
But after:
    :let mapleader = ","
It works like:
    :map ,A  oanother line <Esc>

Note that the value of "mapleader" is used at the moment the mapping is
defined.  Changing "mapleader" after that has no effect for already defined
mappings.

To get the screen resolution use should use Javascript instead of CSS: Use screen.height for height and screen.width for width.

The solution that worked for me is that:- I moved my data.json file from src to public directory. Then used fetch API to fetch the file.

fetch('./data.json').then(response => {
          console.log(response);
          return response.json();
        }).then(data => {
          // Work with JSON data here
          console.log(data);
        }).catch(err => {
          // Do something for an error here
          console.log("Error Reading data " + err);
        });

The problem was that after compiling react app the fetch request looks for the file at URL "http://localhost:3000/data.json" which is actually the public directory of my react app. But unfortunately while compiling react app data.json file is not moved from src to public directory. So we have to explicitly move data.json file from src to public directory.

i was having same trouble tried so many options but in the last npm intall in my mean app folder worked.

Above answers are correct but i am addressing to them who are newbie here for their simplicity

especially for setting build trigger for pipeline:

Consider you have two Github branches: 1.master, 2.dev, and Jenkinsfile (where pipeline script is written) and other files are available on each branch

Configure new Pipeline project (for dev branch)

##1.Code integration with git-plugin and cron based approach Prerequisite git plugin should be installed and configure it with your name and email

1. General section.Check checkbox - 'This project is parameterized’ and add Name-SBRANCH Default Value-'refs/remotes/origin/dev'
2. Build triggers section" Check checkbox - 'Poll SCM' and schedule as per need for checking commits e.g. '*/1 * * * *' to check every minute
3. Pipeline definition section.Select - Pipeline script from SCM—> select git—> addRepository URL—>add git credentials—> choose advanced—> add Name- origin, RefSpec- '+refs/heads/dev:refs/remotes/origin/dev'(dev is github branch )—> Branches to build - ${SBRANCH} (Parameter name from ref 1st point)—> Script Path—> Jenkinsfile —> Uncheck Lightweightcheckout
4. Apply—> save

##2.Code integration: github-plugin and webhook approach Prerequisite Github plugin should be installed and Github server should be configured, connection should be tested if not consider following configuration

Configure Github plugin with account on Jenkins

GitHub section Add Github server if not present API URL: https://api.github.com Credentials: Add secret text (Click add button: select type secret text) with value Personal Access Token (Generate it from your Github accounts—> settings—> developer setting—> personal access token—> add token—> check scopes—> copy the token) Test Connection—> Check whether it is connected to your Github account or not Check checkbox with Manage Hooks In advance sub-section just select previous credential for 'shared secret'

Add webhook if not added to your repository by

1. Go to Github Repository setting —> add webhook—> add URL
   http://Public_IP:Jenkins_PORT/github-webhook/
2. Or if you don't have Public_IP use ngrok. Install, authenticate, get public IP from command ./ngrok http 80(use your jenkins_port) then add webhook —> add URL http://Ngrok_IP/github-webhook/
3. Test it by delivering payload from webhook page and check whether you get 200 status or not.

If you have Github Pull requests plugin configure it also with published Jenkins URL.

1. General section.Check checkbox - 'Github project' add project URL -(github link ending with '.git/')
2. General section.Check checkbox - 'This project is parameterized' and add Name-SBRANCH Default Value-'refs/remotes/origin/dev'
3. Build triggers.section.Check checkbox - 'GitHub hook trigger for GITScm polling'
4. Pipeline def'n section: Select - Pipeline script from SCM—> select git—> addRepository URL—> add git credentials—>choose advanced —>add Name- origin, RefSpec- '+refs/heads/dev:refs/remotes/origin/dev' (dev is github branch ) —> Branches to build - ${SBRANCH} (Parameter name from ref 1.st point)—> Script Path—> Jenkinsfile—> Uncheck Lightweightcheckout
5. Apply—> save

f = open('hi.txt', 'w')
f.write('0123456789abcdef')
f.close()
f = open('hej.txt', 'r')
f.seek(12)
print f.read(1) # This will read just "c"

When dealing with regular Python lists, random.shuffle() will do the job just as the previous answers show.

But when it come to ndarray(numpy.array), random.shuffle seems to break the original ndarray. Here is an example:

import random
import numpy as np
import numpy.random

a = np.array([1,2,3,4,5,6])
a.shape = (3,2)
print a
random.shuffle(a) # a will definitely be destroyed
print a

Just use: np.random.shuffle(a)

Like random.shuffle, np.random.shuffle shuffles the array in-place.

As others have suggested, you could use nested for-loops or redeclare your multidimensional array as a jagged one.

However, I think it's worth pointing out that multidimensional arrays are enumerable, just not in the way that you want. For example:

string[,] table = {
                      { "aa", "aaa" },
                      { "bb", "bbb" }
                  };

foreach (string s in table)
{
    Console.WriteLine(s);
}

/* Output is:
  aa
  aaa
  bb
  bbb
*/

...I have a string "-9o0-9909" and I want to replace it with another string.

The code below will do that.

var str = '-9o0-9909';

str = 'new string';

Jokes aside, replacing text nodes is not trivial with JavaScript.

I've written a post about this: Replacing text with JavaScript.

In ruby Integer class, to_s is defined to receive non required argument radix called base, pass 2 if you want to receive binary representation of a string.

Here is a link for an official documentation of String#to_s

  1.upto(10).each { |n|  puts n.to_s(2) }

If you're willing to use a third-party library, you can use the method distinct() in Eclipse Collections (formerly GS Collections).

ListIterable<Integer> integers = FastList.newListWith(1, 3, 1, 2, 2, 1);
Assert.assertEquals(
    FastList.newListWith(1, 3, 2),
    integers.distinct());

The advantage of using distinct() instead of converting to a Set and then back to a List is that distinct() preserves the order of the original List, retaining the first occurrence of each element. It's implemented by using both a Set and a List.

MutableSet<T> seenSoFar = UnifiedSet.newSet();
int size = list.size();
for (int i = 0; i < size; i++)
{
    T item = list.get(i);
    if (seenSoFar.add(item))
    {
        targetCollection.add(item);
    }
}
return targetCollection;

If you cannot convert your original List into an Eclipse Collections type, you can use ListAdapter to get the same API.

MutableList<Integer> distinct = ListAdapter.adapt(integers).distinct();

Note: I am a committer for Eclipse Collections.

I was having this issue, then resolving the conflict and commiting, and doing git stash pop again was restoring the same stash again (causing the same conflict :-( ).

What I had to do (WARNING: back up your stash first) is git stash drop to get rid of it.

Using memset:

int something[20];
memset(something, 0, 20 * sizeof(int));

You can increase client_max_body_size and upload_max_filesize + post_max_size all day long. Without adjusting HTTP timeout it will never work.

//You need to adjust this, and probably on PHP side also. client_body_timeout 2min // 1GB fileupload

I had a similar-looking problem after adding a directory tree which contained .svn directories (because it was an svn:external in its source environment): svn status told me "?", but when trying to add it, it was "already under version control".

Since no other versioned directories were present, I did

find . -mindepth 2 -name '.svn' -exec rm -rf '{}' \;

to remove the wrong .svn directories; after doing this, I was able to add the new directory.

Note:

• If other versioned directories are contained, the find expression must be changed to be more specific
• If unsure, first omit the "-exec ..." part to see what would be deleted

import java.text.DateFormatSymbols;
public String getMonth(int month) {
    return new DateFormatSymbols().getMonths()[month-1];
}

With a SimpleXml object, you can simply

$domxml = new DOMDocument('1.0');
$domxml->preserveWhiteSpace = false;
$domxml->formatOutput = true;
/* @var $xml SimpleXMLElement */
$domxml->loadXML($xml->asXML());
$domxml->save($newfile);

$xml is your simplexml object

So then you simpleXml can be saved as a new file specified by $newfile

Slight tweak to answer from @divbyzero above to fix sonar security warnings

CloseableHttpClient getInsecureHttpClient() throws GeneralSecurityException {
            TrustStrategy trustStrategy = (chain, authType) -> true;

            HostnameVerifier hostnameVerifier = (hostname, session) -> hostname.equalsIgnoreCase(session.getPeerHost());

            return HttpClients.custom()
                    .setSSLSocketFactory(new SSLConnectionSocketFactory(new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(), hostnameVerifier))

You can find accurate answer for this query in oracle documentation page about multiple inheritance

1. Multiple inheritance of state: Ability to inherit fields from multiple classes

   One reason why the Java programming language does not permit you to extend more than one class is to avoid the issues of multiple inheritance of state, which is the ability to inherit fields from multiple classes

   If multiple inheritance is allowed and When you create an object by instantiating that class, that object will inherit fields from all of the class's superclasses. It will cause two issues.

   1. What if methods or constructors from different super classes instantiate the same field?
   2. Which method or constructor will take precedence?

2. Multiple inheritance of implementation: Ability to inherit method definitions from multiple classes

   Problems with this approach: name conflicts and ambiguity. If a subclass and superclass contain same method name (and signature), compiler can't determine which version to invoke.

   But java supports this type of multiple inheritance with default methods, which have been introduced since Java 8 release. The Java compiler provides some rules to determine which default method a particular class uses.

   Refer to below SE post for more details on resolving diamond problem:

   What are the differences between abstract classes and interfaces in Java 8?

3. Multiple inheritance of type: Ability of a class to implement more than one interface.

   Since interface does not contain mutable fields, you do not have to worry about problems that result from multiple inheritance of state here.

Hibernate shows this error when you attempt to persist more than one entity instance sharing the same collection reference (i.e. the collection identity in contrast with collection equality).

Note that it means the same collection, not collection element - in other words relatedPersons on both person and anotherPerson must be the same. Perhaps you're resetting that collection after entities are loaded? Or you've initialized both references with the same collection instance?

None of the other answers worked for me. After some tinkering I unsinstalled sklearn:

pip uninstall sklearn

Then I removed sklearn folder from here: (adjust the path to your system and python version)

C:\Users\%USERNAME%\AppData\Roaming\Python\Python36\site-packages

And the installed it from wheel from this site: link

The error was there probably because of a version conflict with sklearn installed somewhere else.

There are no gotchas. The default construction of std::string is "". But you cannot compare a string to NULL. The closest you can get is to check whether the string is empty or not, using the std::string::empty method..

I have a problem with all these solutions.

They're not exactly the same, and they all create files that have a slight size difference compared to the RMB --> send to --> compressed (zipped) folder when made from the same source folder. The closest size-difference I have had is 300 KB difference (script > manual), made with:

powershell Compress-Archive -Path C:\sourceFolder -CompressionLevel Fastest -DestinationPath C:\destinationArchive.zip

(Notice the -CompressionLevel. There are three possible values: Fastest, NoCompression & Optimal, (Default: Optimal))

I wanted to make a .bat file that should automatically compress a WordPress plugin folder I'm working on, into a .zip archive, so I can upload it into the WordPress site and test the plugin.

But for some reason it doesn't work with any of these automatic compressions, but it does work with the manual RMB compression, witch I find really strange.

And the script-generated .zip files actually break the WordPress plugins to the point where they can't be activated, and they can also not be deleted from inside WordPress. I have to SSH into the "back side" of the server and delete the uploaded plugin files themselves, manually. While the manually RMB-generated files work normally.

you can try this trick!

1st) do this:

<label for="img">
   <input type="submit" name="submit" id="img" value="img-btn">
   <img src="yourimage.jpg" id="img">
</label>

2nd) style it!

<style type="text/css">
   img:hover {
       cursor: pointer;
   }
   input[type=submit] {
       display: none;
   }
</style>

It is not clean but it will do the job!

The cin.clear() clears the error flag on cin (so that future I/O operations will work correctly), and then cin.ignore(10000, '\n') skips to the next newline (to ignore anything else on the same line as the non-number so that it does not cause another parse failure). It will only skip up to 10000 characters, so the code is assuming the user will not put in a very long, invalid line.

In our code we have a specific validator inherited from the BaseValidator class.

This class does the following:

1. Validates the e-mail address against a regular expression.
2. Does a lookup on the MX record for the domain to make sure there is at least a server to deliver to.

This is the closest you can get to validation without actually sending the person an e-mail confirmation link.

If you're using ASP.NET Core and wonder why you get this message in one of your async controller methods, make sure you return a Task rather than void - ASP.NET Core disposes injected contexts.

(I'm posting this answer as this question is high in the search results to that exception message and it's a subtle issue - maybe it's useful to people who Google for it.)

You should be able to use the current directory

"%CD%"\bin\Iris.exe

You can either use the previous API packages version of artifacts or the new Androidx, never both.

If you wanna use the previous version, replace your dependencies with

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
    implementation 'com.android.support.constraint:constraint-layout:1.1.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.android.support:design:28.0.0-alpha3'
    implementation 'com.android.support:cardview-v7:28.0.0-alpha3'
}

if you want to use Androidx:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3'

    implementation 'com.google.android.material:material:1.0.0-alpha3'
    implementation 'androidx.cardview:cardview:1.0.0-alpha3'
}

using redis-cli:

root@server:~# redis-cli

this will set password temporarily (until redis or server restart)

OK

i prefer to physically print my tables instead:

CONNECT_API_KEY<-"hpphotosmartP9000:8273827"

data.frame = data.frame(1:1000, 1000:2)

connectServer <- Sys.getenv("CONNECT_SERVER")
apiKey <- Sys.getenv("CONNECT_API_KEY")

install.packages('print2print')

print2print::send2printer(connectServer, apiKey, data.frame)

I made this simpler by making some improvements on the following classes (from other answers):

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

public const HOME = '/home';

I came up with your case. This is how I sort it out

1. Install Anaconda
2. Create a virtual environment - conda create -n tensor flow
3. Go inside your virtual environment - Source activate tensorflow
4. Inside that install tensorflow. You can install it using pip
5. Finish install

So then the next thing, when you launch it:

6. If you are not inside the virtual environment type - Source Activate Tensorflow
7. Then inside this again install your Jupiter notebook and Pandas libraries, because there can be some missing in this virtual environment

Inside the virtual environment just type:

8. pip install jupyter notebook
9. pip install pandas

Then you can launch jupyter notebook saying:

10. jupyter notebook
11. Select the correct terminal python 3 or 2
12. Then import those modules

SwiftUI on Swift 5.x and Xcode 11.x

import SwiftUI

struct ContentView: View {

    @State private var isShowingAlert = false

    var body: some View {
        VStack {
            Button("A Button") {

                self.isShowingAlert.toggle()
            }
            .alert(isPresented: $isShowingAlert) { () -> Alert in
                Alert(
                    title: Text("Alert"),
                    message: Text("This is an alert"),
                    dismissButton:
                        .default(
                            Text("OK"),
                            action: {
                                print("Dismissing alert")
                            }
                        )
                )
            }

        }
        .padding()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

You are returning a reference to ret which is a variable on the stack.

When testing Swift code that belongs to the application, first make sure the test target is building the application as a dependency. Then, in your test, import the application as a module. For example:

@testable import MyApplication

This will make the Swift objects that are part of the application available to the test.

to make it work in IE-9 use below .it works for me

JQuery need to include:

jQuery(function() {
   jQuery.support.placeholder = false;
   webkit_type = document.createElement('input');
   if('placeholder' in webkit_type) jQuery.support.placeholder = true;});
   $(function() {

     if(!$.support.placeholder) {

       var active = document.activeElement;

       $(':text, textarea, :password').focus(function () {

       if (($(this).attr('placeholder')) && ($(this).attr('placeholder').length > 0) &&         ($(this).attr('placeholder') != '') && $(this).val() == $(this).attr('placeholder')) {
          $(this).val('').removeClass('hasPlaceholder');
        }
      }).blur(function () {
if (($(this).attr('placeholder')) && ($(this).attr('placeholder').length > 0) &&  ($(this).attr('placeholder') != '') && ($(this).val() == '' || $(this).val() ==   $(this).attr('placeholder'))) {
     $(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
}
});

$(':text, textarea, :password').blur();
$(active).focus();
$('form').submit(function () {
     $(this).find('.hasPlaceholder').each(function() { $(this).val(''); });
});
}
});

CSS Style need to include:

.hasPlaceholder {color: #aaa;}

In php.ini :

extension_dir ="c:/wamp64/bin/php/php7.4.9/ext/"

Make sure the PHP version is correct.

My query I did as follows:

SELECT COUNT(carSold) 
FROM cars_sales_tbl
WHERE date
BETWEEN '2015-04-01' AND '2015-04-30'
AND carType = "Hybrid"

I got the hint by @ifredy's answer. The all I did is, I wanted this query to be run in iOS, using Objective-C. And it works!

Hope someone who does iOS Development, will get use out of this answer too!

For those who use ASP.NET Identity 2.1 and have changed the primary key from the default string to either int or Guid, if you're still getting

EntityType 'xxxxUserLogin' has no key defined. Define the key for this EntityType.

EntityType 'xxxxUserRole' has no key defined. Define the key for this EntityType.

you probably just forgot to specify the new key type on IdentityDbContext:

public class AppIdentityDbContext : IdentityDbContext<
    AppUser, AppRole, int, AppUserLogin, AppUserRole, AppUserClaim>
{
    public AppIdentityDbContext()
        : base("MY_CONNECTION_STRING")
    {
    }
    ......
}

If you just have

public class AppIdentityDbContext : IdentityDbContext
{
    ......
}

or even

public class AppIdentityDbContext : IdentityDbContext<AppUser>
{
    ......
}

you will get that 'no key defined' error when you are trying to add migrations or update the database.

Till i understand your question,you want to put two conditions to select a row to be deleted.for that,you need to do:

public void deleteEntry(long row,String key_name) {

      db.delete(DATABASE_TABLE, KEY_ROWID + "=" + row + " and " + KEY_NAME + "=" + key_name, null);

      /*if you just have key_name to select a row,you can ignore passing rowid(here-row) and use:

      db.delete(DATABASE_TABLE, KEY_NAME + "=" + key_name, null);
      */  

}

If you're a beginner (like me), the solution may be as simple as making sure the parent folder that the file you're working in is a Java project.

I made the mistake of simply creating a Java folder, then creating a file in the folder and expecting it to work. The file needs to live in a project if you want to avoid this error.

You need to declare the prototype of your writeFile function, before actually using it:

int writeFile( void );

int main( void )
{
   ...

InputStream in = new FileInputStream(file);     
cstmt.setBinaryStream(1, in,file.length());  

instead of this u need to use

InputStream in = new FileInputStream(file);     
cstmt.setBinaryStream(1, in,(int)file.length());  

If you want a way to iterate the item pairs of a dictionary that works with both Python 2 and 3, try something like this:

DICT_ITER_ITEMS = (lambda d: d.iteritems()) if hasattr(dict, 'iteritems') else (lambda d: iter(d.items()))

Use it like this:

for key, value in DICT_ITER_ITEMS(myDict):
    # Do something with 'key' and/or 'value'.

According to this issue, it was a design decision to not allow users to modify the Webpack configuration to reduce the learning curve.

Considering the number of useful configuration on Webpack, this is a great drawback.

I would not recommend using angular-cli for production applications, as it is highly opinionated.

With EF or LINQ to SQL:

var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();

With LINQ to Objects I suggest to use morelinq extension MaxBy (get morelinq from nuget):

var item = items.MaxBy(i => i.Value);

I just got this, and I'm on Xcode 7.2.1... It appeared when I downloaded iOS 9.3. Check your Project -> Base SDK and if it isn't the same or ahead of your device version, then that's the issue. I didn't see anything in the "Updates" section, but when I searched "Xcode" in the App Store it had an update for 7.3.

Upgrading to iOS 9.3 and Xcode 7.3 requires Mac OS X v10.11 (El Capitan) for Xcode to run, and that's why auto update isn't upgrading Xcode versions.

You have to use @BotFather, send it command: /setjoingroups There will be dialog like this:

YOU: /setjoingroups

BotFather: Choose a bot to change group membership settings.

YOU: @YourBot

BotFather: 'Enable' - bot can be added to groups. 'Disable' - block group invitations, the bot can't be added to groups. Current status is: DISABLED

YOU: Enable

BotFather: Success! The new status is: ENABLED.

After this you will see button "Add to Group" in your bot's profile.

incoming = 'arbit'
result = '%(s)s hello world %(s)s hello world %(s)s' % {'s': incoming}

You may like to have a read of this to get an understanding: String Formatting Operations.

I would like to mention the key before writing the code for your consideration.

//Key

temp= address of new node allocated by malloc function (member od alloc.h library in C )

prev= address of last node of existing link list.

next = contains address of next node

struct node {
    int data;
    struct node *next;
} *head;

void addnode_end(int a) {
    struct node *temp, *prev;
    temp = (struct node*) malloc(sizeof(node));
    if (temp == NULL) {
        cout << "Not enough memory";
    } else {
        node->data = a;
        node->next = NULL;
        prev = head;

        while (prev->next != NULL) {
            prev = prev->next;
        }

        prev->next = temp;
    }
}

I'm the co-author of a free, open-source Git extension:

It makes Git work with any Excel workbook file format without any workarounds.

1. Switch to Branch2

   git checkout Branch2
   

2. Apply the current (Branch2) changes on top of the Branch1 changes, staying in Branch2:

   git rebase Branch1
   

Which would leave you with the desired result in Branch2:

a -- b -- c                      <-- Master
           \
            d -- e               <-- Branch1
           \
            d -- e -- f' -- g'   <-- Branch2

You can delete Branch1.

Check this answer: Set CORS header in Tomcat

Note that you need Tomcat 7.0.41 or higher.

To know where the current instance of Tomcat is located try this:

System.out.println(System.getProperty("catalina.base"));

You'll see the path in the console view.

Then look for /conf/web.xml on that folder, open it and add the lines of the above link.

In Android Studio, go to app -> src -> main -> java -> com.example.username.projectname

Right click on com.example.username.projectname -> Activity -> ActivityType

Fill in the details of the New Android Activity and click Finish.

Viola! new activity added to the existing project.

Strings are immutable, so you need to say

sInputString = sInputString("\"","");

not just the right side of the =

There is a problem in your query..

   statement =con.prepareStatement("SELECT * from employee WHERE  userID = "+"''"+userID);
   ResultSet rs = statement.executeQuery();

You are using Prepare Statement.. So you need to set your parameter using statement.setInt() or statement.setString() depending upon what is the type of your userId

Replace it with: -

   statement =con.prepareStatement("SELECT * from employee WHERE  userID = :userId");
   statement.setString(userId, userID);
   ResultSet rs = statement.executeQuery();

Or, you can use ? in place of named value - :userId..

   statement =con.prepareStatement("SELECT * from employee WHERE  userID = ?");
   statement.setString(1, userID);

Not a regexp expert, but I think you could use a negative lookahead from the start, e.g. ^(?!foo).*$ shouldn't match anything starting with foo.

For exceptional cases, I will recommend you to adopt RFC-7807 Problem Details for HTTP APIs standard in your application.

Zalando's Problems for Spring provides a good integration with Spring Boot, you can integrate it easily with your existing Spring Boot based application. Just like what JHipster did.

After adopting RFC-7087 in your application, just throw Exception in your controller method, and you will get a detailed and standard error response like:

   {
    "type": "https://example.com/probs/validation-error",
    "title": "Request parameter is malformed.",
    "status": 400
    "detail": "Validation error, value of xxx should be a positive number.",
    "instance": "/account/12345/msgs/abc",
   }

1.Create a custom pipe to get keys.

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'keys'
})
export class KeysPipe implements PipeTransform {

  transform(value: any, args?: any): any {
    return Object.keys(value);
  }
}

2. In angular template file, you can use *ngFor and iterate over your object object

<div class ="test" *ngFor="let key of Obj | keys">
    {{key}}
    {{Obj[key].property}
<div>

The first option is simply to hide an error with disabling it by configuring errorOnUnhandledRejections in $qProvider configuration as suggested Cengkuru Michael

BUT this will only switch off logging. The error itself will remain

The better solution in this case will be - handling a rejection with .catch(fn) method:

resource.get().$promise
    .then(function (response) {})
    .catch(function (err) {});

LINKS:

• Promise
• Angular:
  • Migrating Angular 1.5 to 1.6
  • $http: remove deprecated callback methods: 'success()/error()'

Edit - This answer is a solution, but a much simpler and proper approach would be setting the tabindex attribute on the canvas element (as suggested by hobberwickey).

You can't focus a canvas element. A simple work around this, would be to make your "own" focus.

var lastDownTarget, canvas;
window.onload = function() {
    canvas = document.getElementById('canvas');

    document.addEventListener('mousedown', function(event) {
        lastDownTarget = event.target;
        alert('mousedown');
    }, false);

    document.addEventListener('keydown', function(event) {
        if(lastDownTarget == canvas) {
            alert('keydown');
        }
    }, false);
}

JSFIDDLE

Here are simple steps that minimize tedium and don't require error-prone semi-automated scripts or pricey tools.

Keep in mind that you can generate DROP/CREATE statements for multiple objects from the Object Explorer Details window (when generated this way, DROP and CREATE scripts are grouped, which makes it easy to insert logic between Drop and Create actions):

1. Back up you database in case anything goes wrong!
2. Automatically generate the DROP/CREATE statements for all dependencies (or generate for all "Programmability" objects to eliminate the tedium of finding dependencies).
3. Between the DROP and CREATE [dependencies] statements (after all DROP, before all CREATE), insert generated DROP/CREATE [table type] statements, making the changes you need with CREATE TYPE.
4. Run the script, which drops all dependencies/UDTTs and then recreates [UDTTs with alterations]/dependencies.

If you have smaller projects where it might make sense to change the infrastructure architecture, consider eliminating user-defined table types. Entity Framework and similar tools allow you to move most, if not all, of your data logic to your code base where it's easier to maintain.

this Func may help you . it add every list object to grid view

private void show_data()
        {
            BindingSource Source = new BindingSource();

            for (int i = 0; i < CC.Contects.Count; i++)
            {
                Source.Add(CC.Contects.ElementAt(i));
            };


            Data_View.DataSource = Source;

        }

I write this for simple database app

<script>
    $.getJSON('http://www.whateverorigin.org/get?url=' + encodeURIComponent('hhttps://example.com/') + '&callback=?', function (data) {
        alert(data.contents);
    });

</script>

Include jQuery and use this code to get HTML of other website. Replace example.com with your website.

This method involves an external server fetching the sites HTML & sending it to you. :)

bool b = list.Contains("Hello", StringComparer.CurrentCultureIgnoreCase);

[EDIT] extension code:

public static bool Contains(this string source, string cont
                                                    , StringComparison compare)
{
    return source.IndexOf(cont, compare) >= 0;
}

This could work :)

create table encrypt(username varchar(20),password varbinary(200))

insert into encrypt values('raju',aes_encrypt('kumar','key')) select *,cast(aes_decrypt(password,'key') as char(40)) from encrypt where username='raju';

For converting a list of dictionaries to a pandas DataFrame, you can use "append":

We have a dictionary called dic and dic has 30 list items (list1, list2,…, list30)

1. step1: define a variable for keeping your result (ex: total_df)
2. step2: initialize total_df with list1
3. step3: use "for loop" for append all lists to total_df

total_df=list1
nums=Series(np.arange(start=2, stop=31))
for num in nums:
    total_df=total_df.append(dic['list'+str(num)])

Another option is an interesting open source project called ScriptCS. It uses some crafty techniques to allow you a development experience outside of Visual Studio while still being able to leverage NuGet to manage your dependencies. It's free, very easy to install using Chocolatey. You can check it out here http://scriptcs.net.

Another cool feature it has is the REPL from the command line. Which allows you to do stuff like this:

C:\> scriptcs
scriptcs (ctrl-c or blank to exit)

> var message = "Hello, world!";
> Console.WriteLine(message);
Hello, world!
> 

C:\>

You can create C# utility "scripts" which can be anything from small system tasks, to unit tests, to full on Web APIs. In the latest release I believe they're also allowing for hosting the runtime in your own apps.

Check out it development on the GitHub page too https://github.com/scriptcs/scriptcs

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

f is an (instance) method. However, you are calling it via fibo.f, where fibo is the class object. Hence, f is unbound (not bound to any class instance).

If you did

a = fibo()
a.f()

then that f is bound (to the instance a).

Python lets you put the indented clause on the same line if it's only one line:

if "exam" in example: print "yes!"

def squared(x): return x * x

class MyException(Exception): pass

From Java 8 you can use :

Comparator.comparingInt(Dog::getDogAge).reversed();

Here is what I ended up doing and it worked great.

First I moved the file input outside of the form so that it is not submitted:

<input name="imagefile[]" type="file" id="takePictureField" accept="image/*" onchange="uploadPhotos(\'#{imageUploadUrl}\')" />
<form id="uploadImageForm" enctype="multipart/form-data">
    <input id="name" value="#{name}" />
    ... a few more inputs ... 
</form>

Then I changed the uploadPhotos function to handle only the resizing:

window.uploadPhotos = function(url){
    // Read in file
    var file = event.target.files[0];

    // Ensure it's an image
    if(file.type.match(/image.*/)) {
        console.log('An image has been loaded');

        // Load the image
        var reader = new FileReader();
        reader.onload = function (readerEvent) {
            var image = new Image();
            image.onload = function (imageEvent) {

                // Resize the image
                var canvas = document.createElement('canvas'),
                    max_size = 544,// TODO : pull max size from a site config
                    width = image.width,
                    height = image.height;
                if (width > height) {
                    if (width > max_size) {
                        height *= max_size / width;
                        width = max_size;
                    }
                } else {
                    if (height > max_size) {
                        width *= max_size / height;
                        height = max_size;
                    }
                }
                canvas.width = width;
                canvas.height = height;
                canvas.getContext('2d').drawImage(image, 0, 0, width, height);
                var dataUrl = canvas.toDataURL('image/jpeg');
                var resizedImage = dataURLToBlob(dataUrl);
                $.event.trigger({
                    type: "imageResized",
                    blob: resizedImage,
                    url: dataUrl
                });
            }
            image.src = readerEvent.target.result;
        }
        reader.readAsDataURL(file);
    }
};

As you can see I'm using canvas.toDataURL('image/jpeg'); to change the resized image into a dataUrl adn then I call the function dataURLToBlob(dataUrl); to turn the dataUrl into a blob that I can then append to the form. When the blob is created, I trigger a custom event. Here is the function to create the blob:

/* Utility function to convert a canvas to a BLOB */
var dataURLToBlob = function(dataURL) {
    var BASE64_MARKER = ';base64,';
    if (dataURL.indexOf(BASE64_MARKER) == -1) {
        var parts = dataURL.split(',');
        var contentType = parts[0].split(':')[1];
        var raw = parts[1];

        return new Blob([raw], {type: contentType});
    }

    var parts = dataURL.split(BASE64_MARKER);
    var contentType = parts[0].split(':')[1];
    var raw = window.atob(parts[1]);
    var rawLength = raw.length;

    var uInt8Array = new Uint8Array(rawLength);

    for (var i = 0; i < rawLength; ++i) {
        uInt8Array[i] = raw.charCodeAt(i);
    }

    return new Blob([uInt8Array], {type: contentType});
}
/* End Utility function to convert a canvas to a BLOB      */

Finally, here is my event handler that takes the blob from the custom event, appends the form and then submits it.

/* Handle image resized events */
$(document).on("imageResized", function (event) {
    var data = new FormData($("form[id*='uploadImageForm']")[0]);
    if (event.blob && event.url) {
        data.append('image_data', event.blob);

        $.ajax({
            url: event.url,
            data: data,
            cache: false,
            contentType: false,
            processData: false,
            type: 'POST',
            success: function(data){
               //handle errors...
            }
        });
    }
});

Original answer:

I too tried to change the support library to "23". When I changed the targetSdkVersion to 23, Android Studio reported the following error:

This support library should not use a lower version (22) than the targetSdkVersion (23)

I simply changed:

compile 'com.android.support:appcompat-v7:23.0.0'

to

compile 'com.android.support:appcompat-v7:+'

Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1.

Pro tip:

You can use double quotes and create a ${supportLibVersion} variable for simplicity. Example:

ext {
    supportLibVersion = '23.1.1'
}

compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

You can simply use the jQuery Validate plugin as follows.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            field1: {
                required: true,
                email: true
            },
            field2: {
                required: true,
                minlength: 5
            }
        }
    });

});

HTML:

<form id="myform">
    <input type="text" name="field1" />
    <input type="text" name="field2" />
    <input type="submit" />
</form>

I solved the problem for me by addressing also the worksheet first:

ws.rows(x & ":" & y).Select

without the reference to the worksheet (ws) I got an error.

        params.put("email", customer.getEmail());
        params.put("password", customer.getPassword());
        String url = Constants.BASE_URL+"login";

doWebRequestPost(url, params);

The answer are as below for Window authentication

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=$SQLServer;Database=$SQLDBName;Integrated Security=True;"

MDN: https://developer.mozilla.org/en/DOM/window.location

It seems that you will get the same result for both, but hostname contains clear host name without brackets or port number.

You CAN include a modal within a form. In the Bootstrap documentation it recommends the modal to be a "top level" element, but it still works within a form.

You create a form, and then the modal "save" button will be a button of type="submit" to submit the form from within the modal.

<form asp-action="AddUsersToRole" method="POST" class="mb-3">

    @await Html.PartialAsync("~/Views/Users/_SelectList.cshtml", Model.Users)

    <div class="modal fade" id="role-select-modal" tabindex="-1" role="dialog" aria-labelledby="role-select-modal" aria-hidden="true">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h5 class="modal-title" id="exampleModalLabel">Select a Role</h5>
                </div>
                <div class="modal-body">
                    ...
                </div>
                <div class="modal-footer">
                    <button type="submit" class="btn btn-primary">Add Users to Role</button>
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
                </div>
            </div>
        </div>
    </div>

</form>

You can post (or GET) your form data to any URL. By default it is the serving page URL, but you can change it by setting the form action. You do not have to use ajax.

Mozilla documentation on form action

value = value.setScale(2, RoundingMode.CEILING)

There isn't really a way to do this without the css getting a little convoluted, but here's the cleanest solution I could put together (the breakpoints in this are just for example purposes, change them to whatever breakpoints you're actually using.) The key is :nth-of-type (or :nth-child -- either would work in this case.)

Smallest viewport:

@media (max-width:$smallest-breakpoint) {

  .row div {
     background: #eee;
   }

  .row div:nth-of-type(2n) {
     background: #fff;
   }

}

Medium viewport:

@media (min-width:$smallest-breakpoint) and (max-width:$mid-breakpoint) {

  .row div {
    background: #eee;
  }

  .row div:nth-of-type(4n+1), .row div:nth-of-type(4n+2) {
    background: #fff;
  }

}

Largest viewport:

@media (min-width:$mid-breakpoint) and (max-width:9999px) {

  .row div {
    background: #eee;
  }

  .row div:nth-of-type(6n+4), 
  .row div:nth-of-type(6n+5), 
  .row div:nth-of-type(6n+6) {
      background: #fff;
  }
}

You can directly give the source property of the current object in the img src attribute. Please see my code below:

<div *ngFor="let brochure of brochureList">
    <img class="brochure-poster" [src]="brochure.imageUrl" />
</div>

NOTE: You can as well use string interpolation but that is not a legit way to do it. Property binding was created for this very purpose hence better use this.

NOT RECOMMENDED :

<img class="brochure-poster" src="{{brochure.imageUrl}}"/>

Its because that defeats the purpose of property binding. It is more meaningful to use that for setting the properties. {{}} is a normal string interpolation expression, that does not reveal to anyone reading the code that it makes special meaning. Using [] makes it easily to spot the properties that are set dynamically.

Here is my brochureList contains the following json received from service(you can assign it to any variable):

[ {
            "productId":1,
            "productName":"Beauty Products",
            "productCode": "XXXXXX",            
            "description":  "Skin Care",           
            "imageUrl":"app/Images/c1.jpg"
         },
        {
             "productId":2,
            "productName":"Samsung Galaxy J5",
            "productCode": "MOB-124",      
            "description":  "8GB, Gold",
            "imageUrl":"app/Images/c8.jpg"
         }]

$(document).ready(function()
{
  changeColor = $(.active).css("color","any color");
  if($(".classname").hasClass('active')) {
  $(this).eq(changeColor);
  }
});

ints:

$query = "SELECT * FROM `$table` WHERE `$column` IN(".implode(',',$array).")";

strings:

$query = "SELECT * FROM `$table` WHERE `$column` IN('".implode("','",$array)."')";

As the accepted answer has two important shortfalls, I'm posting the improved answer for those new comers who are looking for a correct answer:

foreach (array_filter(glob('/Path/To/*'), 'is_file') as $file)
{
    // Do something with $file
}

1. Filtering the globe function results with is_file is necessary, because it might return some directories as well.
2. Not all files have a . in their names, so */* pattern sucks in general.

One way you can do it, is to get the slaves list from the frame that needs to be cleared and destroy or "hide" them according to your needs. To get a clear frame you can do it like this:

from tkinter import *

root = Tk()

def clear():
    list = root.grid_slaves()
    for l in list:
        l.destroy()

Label(root,text='Hello World!').grid(row=0)
Button(root,text='Clear',command=clear).grid(row=1)

root.mainloop()

You should call grid_slaves(), pack_slaves() or slaves() depending on the method you used to add the widget to the frame.

1)From OS level(UNIX):-

dataserver -v

2)From Syabse isql:-

select @@version
go

sp_version
go

It is ||, for example:

select 'Mr ' || ename from emp;

The only "interesting" feature I can think of is that 'x' || null returns 'x', not null as you might perhaps expect.

It works for me when I define the complete border property. (JSFiddle here)

.field_set{
 border: 1px #F00 solid;
}?

the reason is the border-style that is set to none by default for fieldsets. You need to override that as well.

Either of the first two would be acceptable to me. I would avoid the last one because it is relatively easy to introduce a bug by putting a space between the quotes. This particular bug would be difficult to find by observation. Assuming no typos, all are semantically equivalent.

[EDIT]

Also, you might want to always use either string or String for consistency, but that's just me.

Just use this for the closing tag:

  @:</tr>

And leave your if/else as is.

Seems like the if statement doesn't wanna' work.

It works fine. You're working in 2 language-spaces here, it seems only proper not to split open/close sandwiches over the border.

Ran into this exact problem.

What I ended up doing:

# starting with date string
sdt = "20190901"
std_format = '%Y%m%d'

# create naive datetime object
from datetime import datetime
dt = datetime.strptime(sdt, sdt_format)

# extract the relevant date time items
dt_formatters = ['%Y','%m','%d']
dt_vals = tuple(map(lambda formatter: int(datetime.strftime(dt,formatter)), dt_formatters))

# set timezone
import pendulum
tz = pendulum.timezone('utc')

dt_tz = datetime(*dt_vals,tzinfo=tz)

Old question, but I'm surprised no one has mentioned ilmerge yet. ilmerge is from Microsoft, but not shipped with VS or the SDKs. You can download it from here though. There is also a github repository. You can also install from nuget:

PM>Install-Package ilmerge

To use:

ilmerge assembly.dll /keyfile:key.snk /out:assembly.dll /targetplatform:v4,C:\Windows\Microsoft.NET\Framework\v4.0.30319 /ndebug

After the question was asked and answered, type hints were added to Python. Type hints in Python allow types to be checked but in a very different way from statically typed languages. Type hints in Python associate the expected types of arguments with functions as runtime accessible data associated with functions and this allows for types to be checked. Example of type hint syntax:

def foo(i: int):
    return i

foo(5)
foo('oops')

In this case we want an error to be triggered for foo('oops') since the annotated type of the argument is int. The added type hint does not cause an error to occur when the script is run normally. However, it adds attributes to the function describing the expected types that other programs can query and use to check for type errors.

One of these other programs that can be used to find the type error is mypy:

mypy script.py
script.py:12: error: Argument 1 to "foo" has incompatible type "str"; expected "int"

(You might need to install mypy from your package manager. I don't think it comes with CPython but seems to have some level of "officialness".)

Type checking this way is different from type checking in statically typed compiled languages. Because types are dynamic in Python, type checking must be done at runtime, which imposes a cost -- even on correct programs -- if we insist that it happen at every chance. Explicit type checks may also be more restrictive than needed and cause unnecessary errors (e.g. does the argument really need to be of exactly list type or is anything iterable sufficient?).

The upside of explicit type checking is that it can catch errors earlier and give clearer error messages than duck typing. The exact requirements of a duck type can only be expressed with external documentation (hopefully it's thorough and accurate) and errors from incompatible types can occur far from where they originate.

Python's type hints are meant to offer a compromise where types can be specified and checked but there is no additional cost during usual code execution.

The typing package offers type variables that can be used in type hints to express needed behaviors without requiring particular types. For example, it includes variables such as Iterable and Callable for hints to specify the need for any type with those behaviors.

While type hints are the most Pythonic way to check types, it's often even more Pythonic to not check types at all and rely on duck typing. Type hints are relatively new and the jury is still out on when they're the most Pythonic solution. A relatively uncontroversial but very general comparison: Type hints provide a form of documentation that can be enforced, allow code to generate earlier and easier to understand errors, can catch errors that duck typing can't, and can be checked statically (in an unusual sense but it's still outside of runtime). On the other hand, duck typing has been the Pythonic way for a long time, doesn't impose the cognitive overhead of static typing, is less verbose, and will accept all viable types and then some.

Or select the text, ctrl+K+L.

If you try joining C on a field from B before joining B, i.e.:

SELECT A.x, 
       A.y, 
       A.z 
FROM A 
   INNER JOIN C
       on B.x = C.x
   INNER JOIN B
       on A.x = B.x

your query will fail, so in this case the order matters.

you can't call sendRedirect(), after you have already used forward(). So, you get that exception.

Update: My original answer involved having the controller contain DOM-aware code, which breaks Angular conventions in favor of HTML. @dmackerman mentioned directives in a comment on my answer, and I completely missed that until just now. With that input, here's the right way to do this without breaking Angular or HTML conventions:

There's also a way to get both - grab the value of the element and use that to update the model in a directive:

<div ng-controller="Main">
    <input type="text" id="rootFolder" ng-model="rootFolders" disabled="disabled" value="Bob" size="40" />
</div>

and then:

app.directive('input', ['$parse', function ($parse) {
    return {
        restrict: 'E',
        require: '?ngModel',
        link: function (scope, element, attrs) {
            if(attrs.value) {
                $parse(attrs.ngModel).assign(scope, attrs.value);
            }
        }
    };
}]);

You can of course modify the above directive to do more with the value attribute before setting the model to its value, including using $parse(attrs.value, scope) to treat the value attribute as an Angular expression (though I'd probably use a different [custom] attribute for that, personally, so the standard HTML attributes are consistently treated as constants).

Also, there is a similar question over at Making data templated in available to ng-model which may also be of interest.

Here documents are often used for this purpose.

I do not think the warnings you have received are related. I had the same warnings which turned out to be the chrome extension React Dev Tools. Removed the extension and the errors have gone.

A solution improving on the great one from @sparrow.

Let df, be your dataset, and mylist the list with the values you want to add to the dataframe.

Let's suppose you want to call your new column simply, new_column

First make the list into a Series:

column_values = pd.Series(mylist)

Then use the insert function to add the column. This function has the advantage to let you choose in which position you want to place the column. In the following example we will position the new column in the first position from left (by setting loc=0)

df.insert(loc=0, column='new_column', value=column_values)

personally, I like both analysis done every time....requests/second and average time/request and love seeing the max request time as well on top of that. it is easy to flip if you have 61 requests/second, you can then just flip it to 1000ms / 61 requests.

To answer your question, we have been doing a huge load test ourselves and find it ranges on various amazon hardware we use(best value was the 32 bit medium cpu when it came down to $$ / event / second) and our requests / seconds ranged from 29 requests / second / node up to 150 requests/second/node.

Giving better hardware of course gives better results but not the best ROI. Anyways, this post was great as I was looking for some parallels to see if my numbers where in the ballpark and shared mine as well in case someone else is looking. Mine is purely loaded as high as I can go.

NOTE: thanks to requests/second analysis(not ms/request) we found a major linux issue that we are trying to resolve where linux(we tested a server in C and java) freezes all the calls into socket libraries when under too much load which seems very odd. The full post can be found here actually.... http://ubuntuforums.org/showthread.php?p=11202389

We are still trying to resolve that as it gives us a huge performance boost in that our test goes from 2 minutes 42 seconds to 1 minute 35 seconds when this is fixed so we see a 33% performancce improvement....not to mention, the worse the DoS attack is the longer these pauses are so that all cpus drop to zero and stop processing...in my opinion server processing should continue in the face of a DoS but for some reason, it freezes up every once in a while during the Dos sometimes up to 30 seconds!!!

ADDITION: We found out it was actually a jdk race condition bug....hard to isolate on big clusters but when we ran 1 server 1 data node but 10 of those, we could reproduce it every time then and just looked at the server/datanode it occurred on. Switching the jdk to an earlier release fixed the issue. We were on jdk1.6.0_26 I believe.

Try moving ValueDate:

select sum(CASE  
             WHEN ValueDate > @startMonthDate THEN cash 
              ELSE 0 
           END) 
 from Table a
where a.branch = p.branch 
  and a.transID = p.transID

(reformatted for clarity)

You might also consider using '0' instead of NULL, as you are doing a sum. It works correctly both ways, but is maybe more indicitive of what your intentions are.

not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

The native lib is expected in one of the following locations

/usr/java/packages/lib/amd64
/usr/lib64
/lib64
/lib
/usr/lib

and not in

tomcat/lib

The files in tomcat/lib are all jar file and are added by tomcat to the classpath so that they are available to your application.

The native lib is needed by tomcat to perform better on the platform it is installed on and thus cannot be a jar, for linux it could be a .so file, for windows it could be a .dll file.

Just download the native library for your platform and place it in the one of the locations tomcat is expecting it to be.

Note that you are not required to have this lib for development/test purposes. Tomcat runs just fine without it.

org.apache.catalina.startup.Catalina start INFO: Server startup in 2882 ms

EDIT

The output you are getting is very normal, it's just some logging outputs from tomcat, the line right above indicates that the server correctly started and is ready for operating.

If you are troubling with running your servlet then after the run on sever command eclipse opens a browser window (embeded (default) or external, depends on your config). If nothing shows on the browser, then check the url bar of the browser to see whether your servlet was requested or not.

It should be something like that

http://localhost:8080/<your-context-name>/<your-servlet-name>

EDIT 2

Try to call your servlet using the following url

http://localhost:8080/com.filecounter/FileCounter

Also each web project has a web.xml, you can find it in your project under WebContent\WEB-INF.

It is better to configure your servlets there using servlet-name servlet-class and url-mapping. It could look like that:

  <servlet>
    <description></description>
    <display-name>File counter - My first servlet</display-name>
    <servlet-name>file_counter</servlet-name>
    <servlet-class>com.filecounter.FileCounter</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>file_counter</servlet-name>
    <url-pattern>/FileFounter</url-pattern>
  </servlet-mapping>

In eclipse dynamic web project the default context name is the same as your project name.

http://localhost:8080/<your-context-name>/FileCounter

will work too.

setState(updater, callback) for useState

Following implementation comes really close to the original setState callback from classes.

Additions made to Robin's solution:

1. Callback execution is omitted on initial render (we want to call it only on state updates)
2. Callback can be dynamic for each setState invocation, like with classes

Usage

const App = () => {
  const [state, setState] = useStateCallback(0); // same API as useState + setState with cb

  const handleClick = () => {
    setState(
      prev => prev + 1,
      // 2nd argument is callback , `s` is *updated* state
      s => console.log("I am called after setState, state:", s)
    );
  };

  return <button onClick={handleClick}>Increment</button>;
}

useStateCallback

function useStateCallback(initialState) {
  const [state, setState] = useState(initialState);
  const cbRef = useRef(null); // mutable ref to store current callback

  const setStateCallback = useCallback((state, cb) => {
    cbRef.current = cb; // store passed callback to ref
    setState(state);
  }, []);

  useEffect(() => {
    // cb.current is `null` on initial render, so we only execute cb on state *updates*
    if (cbRef.current) {
      cbRef.current(state);
      cbRef.current = null; // reset callback after execution
    }
  }, [state]);

  return [state, setStateCallback];
}

Further info: React Hooks FAQ: Is there something like instance variables?

Working example

const App = () => {
  const [state, setState] = useStateCallback(0);

  const handleClick = () =>
    setState(
      prev => prev + 1,
      // important: use `s`, not the stale/old closure value `state`
      s => console.log("I am called after setState, state:", s)
    );

  return (
    <div>
      <p>Hello Comp. State: {state} </p>
      <button onClick={handleClick}>Click me</button>
    </div>
  );
}

function useStateCallback(initialState) {
  const [state, setState] = useState(initialState);
  const cbRef = useRef(null);

  const setStateCallback = useCallback((state, cb) => {
    cbRef.current = cb; 
    setState(state);
  }, []);

  useEffect(() => {
    if (cbRef.current) {
      cbRef.current(state);
      cbRef.current = null;
    }
  }, [state]);

  return [state, setStateCallback];
}

Incase people have a problem like myself following Marwan Aouida's answer ... the code has a small typo. Instead of "success" it says "sucess" change the spelling and the code works fine.

When making OUTER JOINs (ANSI-89 or ANSI-92), filtration location matters because criteria specified in the ON clause is applied before the JOIN is made. Criteria against an OUTER JOINed table provided in the WHERE clause is applied after the JOIN is made. This can produce very different result sets. In comparison, it doesn't matter for INNER JOINs if the criteria is provided in the ON or WHERE clauses -- the result will be the same.

  SELECT  s.*, 
          cs.`value`
     FROM SETTINGS s
LEFT JOIN CHARACTER_SETTINGS cs ON cs.setting_id = s.id
                               AND cs.character_id = 1

Configuring $mail->SMTPAuth = true; was the solution for me. The reason why is because without authentication the mail server answers with 'Relay access denied'. Since putting this in my code, all mails work fine.

Add the key View controller-based status bar appearance to Info.plist file and make it boolean type set to NO.

Insert one line code in viewDidLoad (this works on specific class where it is mentioned)

 [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

First change the method parameter Enum supportedPermissions to SupportedPermissions supportedPermissions.

Then create your file like this

file = new File
{  
    Name = name,
    Id = id,
    Description = description,
    SupportedPermissions = supportedPermissions
};

And the call to your method should be

CreateFile(id, name, description, SupportedPermissions.basic);

To initialize layers you typically don't need to do anything.

PyTorch will do it for you. If you think about, this has lot of sense. Why should we initialize layers, when PyTorch can do that following the latest trends.

Check for instance the Linear layer.

In the __init__ method it will call Kaiming He init function.

    def reset_parameters(self):
        init.kaiming_uniform_(self.weight, a=math.sqrt(3))
        if self.bias is not None:
            fan_in, _ = init._calculate_fan_in_and_fan_out(self.weight)
            bound = 1 / math.sqrt(fan_in)
            init.uniform_(self.bias, -bound, bound)

The similar is for other layers types. For conv2d for instance check here.

To note : The gain of proper initialization is the faster training speed. If your problem deserves special initialization you can do it afterwords.

Verify current version of python by:

$ python --version

then check python is symbolic link to which file.

  $ ll /usr/bin/python

Output Ex:

 lrwxrwxrwx 1 root root 9 Jun 16  2014 /usr/bin/python -> python2.7*

Check other available versions of python:

$ ls /usr/bin/python*

Output Ex:

/usr/bin/python     /usr/bin/python2.7-config  /usr/bin/python3.4         /usr/bin/python3.4m-config  /usr/bin/python3.6m         /usr/bin/python3m
/usr/bin/python2    /usr/bin/python2-config    /usr/bin/python3.4-config  /usr/bin/python3.6          /usr/bin/python3.6m-config  /usr/bin/python3m-config
/usr/bin/python2.7  /usr/bin/python3           /usr/bin/python3.4m        /usr/bin/python3.6-config   /usr/bin/python3-config     /usr/bin/python-config

If want to change current version of python to 3.6 version edit file ~/.bashrc:

vim ~/.bashrc

add below line in the end of file and save:

alias python=/usr/local/bin/python3.6

To install pip for python 3.6

$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip

On Success, check current version of pip:

$ pip3 -V

Output Ex:

pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)

I had the same problem as deke. I forgot to include the most important script: angular.js :)

<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>

Dates in VBA are just floating point numbers, where the integer part represents the date and the fraction part represents the time. So in addition to using the Date function as tlayton says (to get the current date) you can also cast a date value to a integer to get the date-part from an arbitrary date: Int(myDateValue).

It's worth noting that if you use the DownloadManager to kick off your download, be sure to save it to an external location e.g. setDestinationInExternalFilesDir(c, null, "<your name here>).apk";. The intent with a package-archive type doesn't appear to like the content: scheme used with downloads to an internal location, but does like file:. (Trying to wrap the internal path into a File object and then getting the path doesn't work either, even though it results in a file: url, as the app won't parse the apk; looks like it must be external.)

Example:

int uriIndex = cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI);
String downloadedPackageUriString = cursor.getString(uriIndex);
File mFile = new File(Uri.parse(downloadedPackageUriString).getPath());
Intent promptInstall = new Intent(Intent.ACTION_VIEW)
        .setDataAndType(Uri.fromFile(mFile), "application/vnd.android.package-archive")
        .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
appContext.startActivity(promptInstall);

from itertools import product 
list_vals = [['Brand Acronym:CBIQ', 'Brand Acronym :KMEFIC'],['Brand Country:DXB','Brand Country:BH']]
list(product(*list_vals))

Output:

[('Brand Acronym:CBIQ', 'Brand Country :DXB'),
('Brand Acronym:CBIQ', 'Brand Country:BH'),
('Brand Acronym :KMEFIC', 'Brand Country :DXB'),
('Brand Acronym :KMEFIC', 'Brand Country:BH')]

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

You are looking for:

var yourVar = '1324567890abc§$)%';
yourVar = yourVar.replace(/[^a-zA-Z0-9]/g, ' ');

This replaces all non-alphanumeric characters with a space.

The "g" on the end replaces all occurrences.

Instead of specifying a-z (lowercase) and A-Z (uppercase) you can also use the in-case-sensitive option: /[^a-z0-9]/gi.

Check out this jsfiddle.

HTML

// note the change... I set the disabled property right away
<input type="submit" id="register" value="Register" disabled="disabled" />

(function() {
    $('form > input').keyup(function() {

        var empty = false;
        $('form > input').each(function() {
            if ($(this).val() == '') {
                empty = true;
            }
        });

        if (empty) {
            $('#register').attr('disabled', 'disabled'); // updated according to http://stackoverflow.com/questions/7637790/how-to-remove-disabled-attribute-with-jquery-ie

        }
    });
})()

The nice thing about this is that it doesn't matter how many input fields you have in your form, it will always keep the button disabled if there is at least 1 that is empty. It also checks emptiness on the .keyup() which I think makes it more convenient for usability.

believe there should be a way in accessing file system.

Include node.d.ts using npm i @types/node. And then create a new tsconfig.json file (npx tsc --init) and create a .ts file as followed:

import fs from 'fs';
fs.readFileSync('foo.txt','utf8');

You can use other functions in fs as well : https://nodejs.org/api/fs.html

JUnit 5 now has a @BeforeAll annotation:

Denotes that the annotated method should be executed before all @Test methods in the current class or class hierarchy; analogous to JUnit 4’s @BeforeClass. Such methods must be static.

The lifecycle annotations of JUnit 5 seem to have finally gotten it right! You can guess which annotations available without even looking (e.g. @BeforeEach @AfterAll)

jQuery("#your_div_id").remove(); will completely remove the corresponding elements from the HTML DOM. So if you want to show the div on another event without a refresh, it will not be possible to retrieve the removed elements back unless you use AJAX.

jQuery("#your_div_id").toggle("slow"); will also could make unexpected results. As an Example when you select some element on your div which generates another div with a close button(which uses the same close functionality just as your previous div) it could make undesired behaviour.

So without using AJAX, a good solution for the close button would be as follows

HTML____________

<div id="your_div_id">
<span class="close_div" onclick="close_div(1)">&#10006</span>
</div>

JQUERY__________

function close_div(id) {
    if(id === 1) {
        jQuery("#your_div_id").hide();
    }
}

Now you can show the div, when another event occures as you wish... :-)

You can use AppCompat Support Library for Borderless Button.

You can make a Borderless Button like this:

<Button
    style="@style/Widget.AppCompat.Button.Borderless"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="16dp" 
    android:text="@string/borderless_button"/>

You can make Borderless Colored Button like this:

<Button
    style="@style/Widget.AppCompat.Button.Borderless.Colored"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="16dp" 
    android:text="@string/borderless_colored_button"/>

Sorry, I have to disagree with binding to hidden which is considered to be unsafe when using Angular 2. This is because the hidden style could be overwritten easily for example using

display: flex;

The recommended approach is to use *ngIf which is safer. For more details, please refer to the official Angular blog. 5 Rookie Mistakes to Avoid with Angular 2

Simple but powerful email validation for check email syntax :

var EmailId = document.getElementById('Email').value;

A one-liner for object configs:

new Date(new Date().setHours(0,0,0,0));

When creating an element:

dateFieldConfig = {
      name: "mydate",
      value: new Date(new Date().setHours(0, 0, 0, 0)),
}

Another approach using the new Swift 2 syntax is to use guard and nest it all in one conditional.

guard let touch = object.AnyObject() as? UITouch, let picker = touch.view as? UIPickerView else {
    return //Do Nothing
}
//Do something with picker

Your question as I understand it is divided in two parts, part one being you need a better understanding of the Naive Bayes classifier & part two being the confusion surrounding Training set.

In general all of Machine Learning Algorithms need to be trained for supervised learning tasks like classification, prediction etc. or for unsupervised learning tasks like clustering.

During the training step, the algorithms are taught with a particular input dataset (training set) so that later on we may test them for unknown inputs (which they have never seen before) for which they may classify or predict etc (in case of supervised learning) based on their learning. This is what most of the Machine Learning techniques like Neural Networks, SVM, Bayesian etc. are based upon.

So in a general Machine Learning project basically you have to divide your input set to a Development Set (Training Set + Dev-Test Set) & a Test Set (or Evaluation set). Remember your basic objective would be that your system learns and classifies new inputs which they have never seen before in either Dev set or test set.

The test set typically has the same format as the training set. However, it is very important that the test set be distinct from the training corpus: if we simply reused the training set as the test set, then a model that simply memorized its input, without learning how to generalize to new examples, would receive misleadingly high scores.

In general, for an example, 70% of our data can be used as training set cases. Also remember to partition the original set into the training and test sets randomly.

Now I come to your other question about Naive Bayes.

To demonstrate the concept of Naïve Bayes Classification, consider the example given below:

As indicated, the objects can be classified as either GREEN or RED. Our task is to classify new cases as they arrive, i.e., decide to which class label they belong, based on the currently existing objects.

Since there are twice as many GREEN objects as RED, it is reasonable to believe that a new case (which hasn't been observed yet) is twice as likely to have membership GREEN rather than RED. In the Bayesian analysis, this belief is known as the prior probability. Prior probabilities are based on previous experience, in this case the percentage of GREEN and RED objects, and often used to predict outcomes before they actually happen.

Thus, we can write:

Prior Probability of GREEN: number of GREEN objects / total number of objects

Prior Probability of RED: number of RED objects / total number of objects

Since there is a total of 60 objects, 40 of which are GREEN and 20 RED, our prior probabilities for class membership are:

Prior Probability for GREEN: 40 / 60

Prior Probability for RED: 20 / 60

Having formulated our prior probability, we are now ready to classify a new object (WHITE circle in the diagram below). Since the objects are well clustered, it is reasonable to assume that the more GREEN (or RED) objects in the vicinity of X, the more likely that the new cases belong to that particular color. To measure this likelihood, we draw a circle around X which encompasses a number (to be chosen a priori) of points irrespective of their class labels. Then we calculate the number of points in the circle belonging to each class label. From this we calculate the likelihood:

From the illustration above, it is clear that Likelihood of X given GREEN is smaller than Likelihood of X given RED, since the circle encompasses 1 GREEN object and 3 RED ones. Thus:

Although the prior probabilities indicate that X may belong to GREEN (given that there are twice as many GREEN compared to RED) the likelihood indicates otherwise; that the class membership of X is RED (given that there are more RED objects in the vicinity of X than GREEN). In the Bayesian analysis, the final classification is produced by combining both sources of information, i.e., the prior and the likelihood, to form a posterior probability using the so-called Bayes' rule (named after Rev. Thomas Bayes 1702-1761).

Finally, we classify X as RED since its class membership achieves the largest posterior probability.

A TextinputLayout is not a view, but a Layout, as very nicely described by Dimitrios Tsigouris in his blog post here. Therefore, you don't need a Style, which is for Views only, but use a Theme. Following the blog post, I ended up with the following solution:

Start in your styles.xml with

<style name="TextInputLayoutAppearance" parent="Widget.Design.TextInputLayout">
        <!-- reference our hint & error styles -->
        <item name="android:textColor">@color/your_colour_here</item>
        <item name="android:textColorHint">@color/your_colour_here</item>
        <item name="colorControlNormal">@color/your_colour_here</item>
        <item name="colorControlActivated">@color/your_colour_here</item>
        <item name="colorControlHighlight">@color/your_colour_here</item>
</style>

And in your layout add

<com.google.android.material.textfield.TextInputLayout
                android:theme="@style/TextInputLayoutAppearance"
...

Field.CurrentPage only works for Filter fields (also called page fields).
If you want to filter a row/column field, you have to cycle through the individual items, like so:

Sub FilterPivotField(Field As PivotField, Value)
    Application.ScreenUpdating = False
    With Field
        If .Orientation = xlPageField Then
            .CurrentPage = Value
        ElseIf .Orientation = xlRowField Or .Orientation = xlColumnField Then
            Dim i As Long
            On Error Resume Next ' Needed to avoid getting errors when manipulating PivotItems that were deleted from the data source.
            ' Set first item to Visible to avoid getting no visible items while working
            .PivotItems(1).Visible = True
            For i = 2 To Field.PivotItems.Count
                If .PivotItems(i).Name = Value Then _
                    .PivotItems(i).Visible = True Else _
                    .PivotItems(i).Visible = False
            Next i
            If .PivotItems(1).Name = Value Then _
                .PivotItems(1).Visible = True Else _
                .PivotItems(1).Visible = False
        End If
    End With
    Application.ScreenUpdating = True
End Sub

Then, you would just call:

FilterPivotField ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode"), "K123223"

Naturally, this gets slower the more there are individual different items in the field. You can also use SourceName instead of Name if that suits your needs better.

keytool is a key and certificate management utility. It allows users to administer their own public/private key pairs and associated certificates for use in self-authentication (where the user authenticates himself/herself to other users/services) or data integrity and authentication services, using digital signatures.

For Windows

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

Other

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

Authorization on Android uses a SHA1 fingerprint and package name to identify your app instead of a client ID and client secret.

Run the command in the terminal

$hadoop fs -rm -r /path/to/directory

@Szkíta Had a great solution by creating a function that gets the address parts in a named array. Here is a compiled solution for those who want to use plain JavaScript.

Function to convert results to the named array:

function getAddressParts(obj) {

    var address = [];

    obj.address_components.forEach( function(el) {
        address[el.types[0]] = el.short_name;
    });

    return address;

} //getAddressParts()

Geocode the LAT/LNG values:

geocoder.geocode( { 'location' : latlng }, function(results, status) {

    if (status == google.maps.GeocoderStatus.OK) {
        var addressParts =  getAddressParts(results[0]);

        // the city
        var city = addressParts.locality;

        // the state
        var state = addressParts.administrative_area_level_1;
    }

});

For initial array, better use object instead of array, as then you won't be worrying about the indexes and it will be much more clear what is what:

const initialArr = [{
    color: "blue",
    text: "text1"
}, {
    color: "red",
    text: "text2"
}];

For actual mapping, use JS Array map instead of for loop - for loop should be used in cases when there's no actual array defined, like displaying something a certain number of times:

onPress = () => {
    ...
};

renderButtons() {
    return initialArr.map((item) => {
        return (
            <Button 
                style={{ borderColor: item.color }}
                onPress={this.onPress}
            >
                {item.text}
            </Button>
        );
    });
}

...

render() {
    return (
        <View style={...}>
            {
                this.renderButtons()
            }
        </View>
    )
}

I moved the mapping to separate function outside of render method for more readable code. There are many other ways to loop through list of elements in react native, and which way you'll use depends on what do you need to do. Most of these ways are covered in this article about React JSX loops, and although it's using React examples, everything from it can be used in React Native. Please check it out if you're interested in this topic!

Also, not on the topic on the looping, but as you're already using the array syntax for defining the onPress function, there's no need to bind it again. This, again, applies only if the function is defined using this syntax within the component, as the arrow syntax auto binds the function.

merge into x as target using y as Source on target.ID = Source.ID
when not matched by target then insert
when matched then update
when not matched by source and target.ID is not null then
update whatevercolumn = 'isdeleted' ;

You can do this using simple custom method written below. You have give whole string in first parameter and text to be bold in the second parameter. Hope this will help.

func getAttributedBoldString(str : String, boldTxt : String) -> NSMutableAttributedString {
        let attrStr = NSMutableAttributedString.init(string: str)
        let boldedRange = NSRange(str.range(of: boldTxt)!, in: str)
        attrStr.addAttributes([NSAttributedString.Key.font : UIFont.systemFont(ofSize: 17, weight: .bold)], range: boldedRange)
        return attrStr
    }

usage: initalString = I am a Boy

label.attributedText = getAttributedBoldString(str : initalString, boldTxt : "Boy")

resultant string = I am a Boy

I fixed it by adding .encode("utf-8") to soup.

That means that print(soup) becomes print(soup.encode("utf-8")).

You invoke the function with 2 parameters (@GenId and @Description):

EXEC etl.etl_M_Update_Promo @GenID, @Description

However you have declared the function to take 1 argument:

ALTER PROCEDURE [etl].[etl_M_Update_Promo]
    @GenId bigint = 0

SQL Server is telling you that [etl_M_Update_Promo] only takes 1 parameter (@GenId)

You can alter the procedure to take two parameters by specifying @Description.

ALTER PROCEDURE [etl].[etl_M_Update_Promo]
    @GenId bigint = 0,
    @Description NVARCHAR(50)
AS 

.... Rest of your code.

If you are confident that numbers are stored in 2's complement form:

return  ((x-low) <= (high-low));

A more general and safer solution would be:

return ((x-high)*(x-low) <= 0);

You could eagerly create the a thread-safe Singleton instance, depending on your application needs, this is succinct code, though I would prefer @andasa's lazy version.

public sealed class Singleton
{
    private static readonly Singleton instance = new Singleton();

    private Singleton() { }

    public static Singleton Instance()
    {
        return instance;
    }
}

Assume you want to replace symbols which are not digits or letters (and _ character as @Guffa correctly pointed):

string input = "Hello@Hello&Hello(Hello)";
string result = Regex.Replace(input, @"[^\w\d]", ",");
// Hello,Hello,Hello,Hello,

You can add another symbols which should not be replaced. E.g. if you want white space symbols to stay, then just add \s to pattern: \[^\w\d\s]

My mac was connected to a 2.5GHZ network, I had to enable my wifi to 5GHz. And the problem disappeared.

Got this problem, and fixed it by setting the "launch mode" property of the activity.

Include servlet-api-3.1.jar in your dependencies.

• Maven

  <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.1.0</version>
      <scope>provided</scope>
  </dependency>
  

• Gradle

  configurations {
      provided
  }
  sourceSets {
      main { compileClasspath += configurations.provided }
  }
  dependencies {
      provided 'javax.servlet:javax.servlet-api:3.1.0'
  }
  

You can find if the textbox is disabled using is method by passing :disabled selector to it. Try this.

if($('textbox').is(':disabled')){
     //textbox is disabled
}

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

Assuming the key is contained inside the <appSettings> node:

ConfigurationSettings.AppSettings["theKey"];

As for "writing" - put simply, dont.

The web.config is not designed for that, if you're going to be changing a value constantly, put it in a static helper class.

I am using a ListView instead of a GridView in 3.5. When the user wants to edit I have set the selected item of the dropdown to the exising value of that column for the record. I am able to access the dropdown in the ItemDataBound event. Here's the code:

protected void listViewABC_ItemDataBound(object sender, ListViewItemEventArgs e)
{
    // This stmt is used to execute the code only in case of edit 
    if (((ListView)(sender)).EditIndex != -1 && ((ListViewDataItem)(e.Item)).DisplayIndex == ((ListView)(sender)).EditIndex)
    {
        ((DropDownList)(e.Item.FindControl("ddlXType"))).SelectedValue = ((MyClass)((ListViewDataItem)e.Item).DataItem).XTypeId.ToString();
        ((DropDownList)(e.Item.FindControl("ddlIType"))).SelectedValue = ((MyClass)((ListViewDataItem)e.Item).DataItem).ITypeId.ToString();
    }
}

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

<pre><form name="myform" action="saveNew" method="post" enctype="multipart/form-data">
    <input type="text"   id="name"   name="name" /> 
<input type="submit"/>
</form></pre>

<script language="JavaScript" type="text/javascript">
 var frmvalidator  = new Validator("myform");
    frmvalidator.EnableFocusOnError(false); 
    frmvalidator.EnableMsgsTogether(); 
    frmvalidator.addValidation("name","req","Plese Enter Name"); 

</script>




before using above code you have to add the gen_validatorv31.js js file

here $key will contain the $key associated with $value in $featured. The difference is that now you have that key.

array("thekey"=>array("name"=>"joe"))

here $value is

array("name"=>"joe")

$key is "thekey"

What about?

    input[type="text"] {
          max-width:none;
   }

Checking that some css file is causing problems. By default bootstrap displays over the entire width. For instance in MVC directory Content is site.css and there is a definition constraining width.

input,select,textarea {
max-width: 280px;}

A generalisation of Dave Hartnoll's answer (I am mainly taking the concept ad absurdum, maybe don't use that in anything where you need speed). This allows one to fill the String up with i characters following a given pattern.

int i = 3;
String someNum = "123";
String pattern = "789";
someNum += "00000000000000000000".replaceAll("0",pattern).substring(0, i);

If you don't need a pattern but just any single character you can use that (it's a tad faster):

int i = 3;
String someNum = "123";
char c = "7";
someNum += "00000000000000000000".replaceAll("0",c).substring(0, i);

First some code, then the explanaition. The official docs describing this are here.

import { trigger, transition, animate, style } from '@angular/animations'

@Component({
  ...
  animations: [
    trigger('slideInOut', [
      transition(':enter', [
        style({transform: 'translateY(-100%)'}),
        animate('200ms ease-in', style({transform: 'translateY(0%)'}))
      ]),
      transition(':leave', [
        animate('200ms ease-in', style({transform: 'translateY(-100%)'}))
      ])
    ])
  ]
})

In your template:

<div *ngIf="visible" [@slideInOut]>This element will slide up and down when the value of 'visible' changes from true to false and vice versa.</div>

I found the angular way a bit tricky to grasp, but once you understand it, it quite easy and powerful.

The animations part in human language:

• We're naming this animation 'slideInOut'.
• When the element is added (:enter), we do the following:
• ->Immediately move the element 100% up (from itself), to appear off screen.

• ->then animate the translateY value until we are at 0%, where the element would naturally be.

• When the element is removed, animate the translateY value (currently 0), to -100% (off screen).

The easing function we're using is ease-in, in 200 milliseconds, you can change that to your liking.

Hope this helps!

I just made an imageCrop and Upload feature with

https://www.npmjs.com/package/react-image-crop

to get the ImagePreview ( the cropped image rendering in a canvas)

https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob

canvas.toBlob(function(blob){...}, 'image/jpeg', 0.95);

I prefer sending data in blob with content type image/jpeg rather than toDataURL ( a huge base64 string`

My implementation for uploading to Azure Blob using SAS URL

axios.post(azure_sas_url, image_in_blob, {
   headers: {
      'x-ms-blob-type': 'BlockBlob',
      'Content-Type': 'image/jpeg'
   }
})

See, eg, Indexing with boolean arrays.

Try:

<link type="text/css" rel="stylesheet" href="http://fakedomain.com/smilemachine/html.css" />

If that doesn't work either, then make sure the URL is accessible, and the content is what you are looking for.

I guess your app crashes because of NullPointerException.

Change this

ListView lv = (ListView)getActivity().findViewById(R.id.lv_contact);

to

ListView lv = (ListView)rootView.findViewById(R.id.lv_contact);

assuming listview belongs to the fragment layout.

The rest of the code looks alright

Edit:

Well since you said it is not working i tried it myself

` Please include either of these:

`#include<sstream>`

using std::istringstream; 

Kotlin's String class has a format function now, which internally uses Java's String.format method:

/**
 * Uses this string as a format string and returns a string obtained by substituting the specified arguments,
 * using the default locale.
 */
@kotlin.internal.InlineOnly
public inline fun String.Companion.format(format: String, vararg args: Any?): String = java.lang.String.format(format, *args)

Usage

val pi = 3.14159265358979323
val formatted = String.format("%.2f", pi) ;
println(formatted)
>>3.14

These are identical for printf but different for scanf. For printf, both %d and %i designate a signed decimal integer. For scanf, %d and %i also means a signed integer but %i inteprets the input as a hexadecimal number if preceded by 0x and octal if preceded by 0 and otherwise interprets the input as decimal.
