I tried all answers provided here: editing phpMyAdmin.conf, changing selinux context for phpmyadmin folder, disabling selinux... but I still got a 'Forbidden' from the web server.

I finally found what I was missing in Edouard Thiel post here :

$ yum install php

then restart httpd :

$ service httpd restart => for centos 6 hots

$ systemctl restart httpd => for centos 7 hosts

What has me amazed is why php is not installed as dependency for phpmyadmin in the first place.

In short, it happens when the application which writes to the sqlite database does not have write permission.

This can be solved in three ways:

1. Granting ownership of db.sqlite3 file and its parent directory (thereby write access also) to the user using chown (Eg: chown username db.sqlite3 )
2. Running the webserver (often gunicorn) as root user (run the command sudo -i before you run gunicorn or django runserver)
3. Allowing read and write access to all users by running command chmod 777 db.sqlite3 (Dangerous option)

Never go for the third option unless you are running the webserver in a local machine or the data in the database is not at all important for you.

Second option is also not recommended. But you can go for it, if you are sure that your application is not vulnerable for code injection attack.

1. Mount the centos live cd and boot
2. Go into rescue mode and wait for it load up
3. Read the terminal to see where it mounted the OS
4. Go into OS
5. vim or nano /etc/selinux/config
6. Make sure SELINUX=enforcing or disabled

You can use

Dispatcher.Invoke(Delegate, object[])

on the Application's (or any UIElement's) dispatcher.

You can use it for example like this:

Application.Current.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));

or

someControl.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));

Ref denotes whether the function can get its hands on the object itself, or only on its value.

Passing by reference is not bound to a language; it's a parameter binding strategy next to pass-by-value, pass by name, pass by need etc...

A sidenote: the class name TestRef is a hideously bad choice in this context ;).

AnyObject is the official way to use a weak reference in Swift.

class MyClass {
    weak var delegate: MyClassDelegate?
}

protocol MyClassDelegate: AnyObject {
}

From Apple:

To prevent strong reference cycles, delegates should be declared as weak references. For more information about weak references, see Strong Reference Cycles Between Class Instances. Marking the protocol as class-only will later allow you to declare that the delegate must use a weak reference. You mark a protocol as being class-only by inheriting from AnyObject, as discussed in Class-Only Protocols.

You must set the setOpaque(true) to true other wise the background will not be painted to the form. I think from reading that if it is not set to true that it will paint some or not any of its pixels to the form. The background is transparent by default which seems odd to me at least but in the way of programming you have to set it to true as shown below.

      JLabel lb = new JLabel("Test");
      lb.setBackground(Color.red);
      lb.setOpaque(true); <--This line of code must be set to true or otherwise the 

From the JavaDocs

setOpaque

public void setOpaque(boolean isOpaque)
  If true the component paints every pixel within its bounds. Otherwise, 
  the component may not paint some or all of its pixels, allowing the underlying 
  pixels to show through.
  The default value of this property is false for JComponent. However, 
  the default value for this property on most standard JComponent subclasses 
   (such as JButton and JTree) is look-and-feel dependent.

Parameters:
isOpaque - true if this component should be opaque
See Also:
isOpaque()

I recently had to build something similar. You can check it out in the snippet below.

The version I had to build uses the same button to start and stop the spinner, but you can manipulate to code if you have a button to start the spin and a different button to stop the spin

Basically, my code looks like this...

I am using mysql and below syntax worked well for me,

ALTER TABLE table_name MODIFY col_name VARCHAR(12);

    [data-value] {
  /* Attribute exists */
}

[data-value="foo"] {
  /* Attribute has this exact value */
}

[data-value*="foo"] {
  /* Attribute value contains this value somewhere in it */
}

[data-value~="foo"] {
  /* Attribute has this value in a space-separated list somewhere */
}

[data-value^="foo"] {
  /* Attribute value starts with this */
}

[data-value|="foo"] {
  /* Attribute value starts with this in a dash-separated list */
}

[data-value$="foo"] {
  /* Attribute value ends with this */
}

Basically an index is a map of all your keys that is sorted in order. With a list in order, then instead of checking every key, it can do something like this:

1: Go to middle of list - is higher or lower than what I'm looking for?

2: If higher, go to halfway point between middle and bottom, if lower, middle and top

3: Is higher or lower? Jump to middle point again, etc.

Using that logic, you can find an element in a sorted list in about 7 steps, instead of checking every item.

Obviously there are complexities, but that gives you the basic idea.

I know this question is for Bootstrap 3, but as some Bootstrap 4 related question are redirected to this one as duplicates, here's the snippet Bootstrap 4-compatible:

$.validator.setDefaults({
    highlight: function(element) {
        $(element).closest('.form-group').addClass('has-danger');
    },
    unhighlight: function(element) {
        $(element).closest('.form-group').removeClass('has-danger');
    },
    errorElement: 'small',
    errorClass: 'form-control-feedback d-block',
    errorPlacement: function(error, element) {
        if(element.parent('.input-group').length) {
            error.insertAfter(element.parent());
        } else if(element.prop('type') === 'checkbox') {
            error.appendTo(element.parent().parent().parent());
        } else if(element.prop('type') === 'radio') {
            error.appendTo(element.parent().parent().parent());
        } else {
            error.insertAfter(element);
        }
    },
});

The few differences are:

• The use of class has-danger instead of has-error
• Better error positioning radios and checkboxes

It's worth noting that iframes will, regardless of the speed of your users' internet connection or the contents of the iframe, cause a small (0.3s or so) but noticeable slowdown in the speed your page downloads. This is not something you'll see when testing it locally. Actually, this is true for any element added to a page, but iframes seem to be worse.

Since required quite often it might as well be brief:

=1*(A1="")

This will not return 1 if the cell appears empty but contains say a space or a formula of the kind =IF(B1=3,"Yes","") where B1 does not contain 3.

=A1="" will return either TRUE or FALSE but those in an equation are treated as 1 and 0 respectively so multiplying TRUE by 1 returns 1.

Much the same can be achieved with the double unary --:

=--(A1="")  

where when A1 is empty one minus negates TRUE into -1 and the other negates that to 1 (just + in place of -- however does not change TRUE to 1).

I wanted an "expand/collapse" container with a plus and minus button to open and close it. This uses the standard bootstrap event and has animation. This is BS3.

HTML:

<button id="button" type="button" class="btn btn-primary" 
  data-toggle="collapse" data-target="#demo">
  <span class="glyphicon glyphicon-collapse-down"></span> Show
</button>

<div id="demo" class="collapse">
  <ol class="list-group">
      <li class="list-group-item">Warrior</li>
      <li class="list-group-item">Adventurer</li>
      <li class="list-group-item">Mage</li>
  </ol>
</div>

JS:

$(function(){
  $('#demo').on('hide.bs.collapse', function () {
    $('#button').html('<span class="glyphicon glyphicon-collapse-down"></span> Show');
  })
  $('#demo').on('show.bs.collapse', function () {
    $('#button').html('<span class="glyphicon glyphicon-collapse-up"></span> Hide');
  })
})

Example:

Just use an ALTER TABLE... MODIFY... query and add NOT NULL into your existing column definition. For example:

ALTER TABLE Person MODIFY P_Id INT(11) NOT NULL;

A word of caution: you need to specify the full column definition again when using a MODIFY query. If your column has, for example, a DEFAULT value, or a column comment, you need to specify it in the MODIFY statement along with the data type and the NOT NULL, or it will be lost. The safest practice to guard against such mishaps is to copy the column definition from the output of a SHOW CREATE TABLE YourTable query, modify it to include the NOT NULL constraint, and paste it into your ALTER TABLE... MODIFY... query.

table td{
  color:#0000ff;
}

<table>
  <tbody>
    <tr>
    <td>
      <select name="test">
        <option value="Basic">Basic : $30.00 USD - yearly</option>
        <option value="Sustaining">Sustaining : $60.00 USD - yearly</option>
        <option value="Supporting">Supporting : $120.00 USD - yearly</option>
      </select>
    </td>
    </tr>

You can use Bootbox dialog boxes

$(document).ready(function() {

  $('#btnDelete').click(function() {
    bootbox.confirm("Are you sure want to delete?", function(result) {
      alert("Confirm result: " + result);
    });
  });
});

You have to initialize the data directory by running the following command

mysqld --initialize [with random root password]

mysqld --initialize-insecure [with blank root password]

Just wrote a script to do this without too much typing while maintaining portability as setting ~ to be %userprofile% needs a manual setup on each Windows PC while cloning and setting the directory as part of the PATH is mechanical.

https://github.com/yxliang01/Snippets/blob/master/windows/

Delimiters, delimiters...

You really need them when there are multiple statements in your procedure. (in other words, do you have a ; in your code and then more statements/commands? Then, you need to use delimiters).

For such a simpler rpocedure as yours though, you could just do:

CREATE PROCEDURE ProG()
  SELECT * FROM `hs_hr_employee_leave_quota`;

You should set async = false in head. Use post/get instead of ajax.

jQuery.ajaxSetup({ async: false });

    $.post({
        url: 'api.php',
        data: 'id1=' + q + '',
        dataType: 'json',
        success: function (data) {

            id = data[0];
            vname = data[1];

        }
    });

Any - boolean function that returns true when any of object in list satisfies condition set in function parameters. For example:

List<string> strings = LoadList();
boolean hasNonEmptyObject = strings.Any(s=>string.IsNullOrEmpty(s));

Where - function that returns list with all objects in list that satisfy condition set in function parameters. For example:

IEnumerable<string> nonEmptyStrings = strings.Where(s=> !string.IsNullOrEmpty(s));

Exists - basically the same as any but it's not generic - it's defined in List class, while Any is defined on IEnumerable interface.

Alternatively, if you can customize your server response, you could return a 403 Forbidden.

The browser will not open the authentication popup and the jquery callback will be called.

Here's my only-somewhat-contrived example of a case where the null key can be useful:

public class Timer {
    private static final Logger LOG = Logger.getLogger(Timer.class);
    private static final Map<String, Long> START_TIMES = new HashMap<String, Long>();

    public static synchronized void start() {
        long now = System.currentTimeMillis();
        if (START_TIMES.containsKey(null)) {
            LOG.warn("Anonymous timer was started twice without being stopped; previous timer has run for " + (now - START_TIMES.get(null).longValue()) +"ms"); 
        }
        START_TIMES.put(null, now);
    }

    public static synchronized long stop() {
        if (! START_TIMES.containsKey(null)) {
            return 0;
        }

        return printTimer("Anonymous", START_TIMES.remove(null), System.currentTimeMillis());
    }

    public static synchronized void start(String name) {
        long now = System.currentTimeMillis();
        if (START_TIMES.containsKey(name)) {
            LOG.warn(name + " timer was started twice without being stopped; previous timer has run for " + (now - START_TIMES.get(name).longValue()) +"ms"); 
        }
        START_TIMES.put(name, now);
    }

    public static synchronized long stop(String name) {
        if (! START_TIMES.containsKey(name)) {
            return 0;
        }

        return printTimer(name, START_TIMES.remove(name), System.currentTimeMillis());
    }

    private static long printTimer(String name, long start, long end) {
        LOG.info(name + " timer ran for " + (end - start) + "ms");
        return end - start;
    }
}

Sometimes it is located in different places. It depends on the server. You can use find to find it:

 find / -name catalina.out 

If you encounter permission issues, add sudo to the command:

sudo find / -name catalina.out

That's all.

I hope this helps

I have written a node module that provides a wrapper around setInterval using moment durations providing a declarative interface:

npm install every-moment

var every = require('every-moment');

var timer = every(5, 'seconds', function() {
    console.log(this.duration);
});

every(2, 'weeks', function() {
    console.log(this.duration);
    timer.stop();
    this.set(1, 'week');
    this.start();
});

https://www.npmjs.com/package/every-moment

You will have to use a flag shared between the main thread and the BackgroundWorker, such as BackgroundWorker.CancellationPending. When you want the BackgroundWorker to exit, just set the flag using BackgroundWorker.CancelAsync().

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

So this is a little bit of a subtle point, because while Python only passes variables by value, every variable in Python is a reference. If you want to be able to change your values with a function call, what you need is a mutable object. For example:

l = [0]

def set_3(x):
    x[0] = 3

set_3(l)
print(l[0])

In the above code, the function modifies the contents of a List object (which is mutable), and so the output is 3 instead of 0.

I write this answer only to illustrate what 'by value' means in Python. The above code is bad style, and if you really want to mutate your values you should write a class and call methods within that class, as MPX suggests.

In HTML, SGML and XML, ⁽¹⁾ attributes cannot be repeated, and should only be defined in an element once.

So your example:

<span style="color:blue" style="font-style:italic">Test</span>

is non-conformant to the HTML standard, and will result in undefined behaviour, which explains why different browsers are rendering it differently.

Since there is no defined way to interpret this, browsers can interpret it however they want and merge them, or ignore them as they wish.

^{(1): Every article I can find states that attributes are "key/value" pairs or "attribute-value" pairs, heavily implying the keys must be unique. The best source I can find states:}

^{Attribute names (id and status in this example) are subject to the same restrictions as other names in XML; they need not be unique across the whole DTD, however, but only within the list of attributes for a given element. (Emphasis mine.)}

In case anyone are still interested in this subject, I find that the best approach for filtering lists is to create a generic Filter class and use it with some base reflection/generics techniques contained in the Java old school SDK package. Here's what I did:

public class GenericListFilter<T> extends Filter {

    /**
     * Copycat constructor
     * @param list  the original list to be used
     */
    public GenericListFilter (List<T> list, String reflectMethodName, ArrayAdapter<T> adapter) {
        super ();

        mInternalList = new ArrayList<>(list);
        mAdapterUsed  = adapter;

        try {
            ParameterizedType stringListType = (ParameterizedType)
                    getClass().getField("mInternalList").getGenericType();
            mCompairMethod =
                    stringListType.getActualTypeArguments()[0].getClass().getMethod(reflectMethodName);
        }
        catch (Exception ex) {
            Log.w("GenericListFilter", ex.getMessage(), ex);

            try {
                if (mInternalList.size() > 0) {
                    T type = mInternalList.get(0);
                    mCompairMethod = type.getClass().getMethod(reflectMethodName);
                }
            }
            catch (Exception e) {
                Log.e("GenericListFilter", e.getMessage(), e);
            }

        }
    }

    /**
     * Let's filter the data with the given constraint
     * @param constraint
     * @return
     */
    @Override protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();
        List<T> filteredContents = new ArrayList<>();

        if ( constraint.length() > 0 ) {
            try {
                for (T obj : mInternalList) {
                    String result = (String) mCompairMethod.invoke(obj);
                    if (result.toLowerCase().startsWith(constraint.toString().toLowerCase())) {
                        filteredContents.add(obj);
                    }
                }
            }
            catch (Exception ex) {
                Log.e("GenericListFilter", ex.getMessage(), ex);
            }
        }
        else {
            filteredContents.addAll(mInternalList);
        }

        results.values = filteredContents;
        results.count  = filteredContents.size();
        return results;
    }

    /**
     * Publish the filtering adapter list
     * @param constraint
     * @param results
     */
    @Override protected void publishResults(CharSequence constraint, FilterResults results) {
        mAdapterUsed.clear();
        mAdapterUsed.addAll((List<T>) results.values);

        if ( results.count == 0 ) {
            mAdapterUsed.notifyDataSetInvalidated();
        }
        else {
            mAdapterUsed.notifyDataSetChanged();
        }
    }

    // class properties
    private ArrayAdapter<T> mAdapterUsed;
    private List<T> mInternalList;
    private Method  mCompairMethod;
}

And afterwards, the only thing you need to do is to create the filter as a member class (possibly within the View's "onCreate") passing your adapter reference, your list, and the method to be called for filtering:

this.mFilter = new GenericFilter<MyObjectBean> (list, "getName", adapter);

The only thing missing now, is to override the "getFilter" method in the adapter class:

@Override public Filter getFilter () {
     return MyViewClass.this.mFilter;
}

All done! You should successfully filter your list - Of course, you should also implement your filter algorithm the best way that describes your need, the code bellow is just an example.. Hope it helped, take care.

It is more Ruby-like to ask objects whether they respond to a method you need or not, using respond_to?. This allows both minimal interface and implementation unaware programming.

It is not always applicable of course, thus there is still a possibility to ask about more conservative understanding of "type", which is class or a base class, using the methods you're asking about.

How Magento log cleaning can be done both manually, automatically and other Magento database maintenance. Below the three things are most important of Magento database maintenance and optimization techniques;

• Log Cleaning
• Smart use of MySQL updated versions
• Buffer pool size settings

I've implemented cross-browser compatible page to test browser's refresh behavior (here is the source code) and get results similar to @some, but for modern browsers:

Note: This answer is a pure Gradle answer, I use this in IntelliJ on a regular basis but I don't know how the integration is with Android Studio. I am a believer in knowing what is going on for me, so this is how I use Gradle and Android.

TL;DR Full Example - https://github.com/ethankhall/driving-time-tracker/

Disclaimer: This is a project I am/was working on.

Gradle has a defined structure ( that you can change, link at the bottom tells you how ) that is very similar to Maven if you have ever used it.

Project Root
+-- src
|   +-- main (your project)
|   |   +-- java (where your java code goes)
|   |   +-- res  (where your res go)
|   |   +-- assets (where your assets go)
|   |   \-- AndroidManifest.xml
|   \-- instrumentTest (test project)
|       \-- java (where your java code goes)
+-- build.gradle
\-- settings.gradle

If you only have the one project, the settings.gradle file isn't needed. However you want to add more projects, so we need it.

Now let's take a peek at that build.gradle file. You are going to need this in it (to add the android tools)

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.3'
    }
}

Now we need to tell Gradle about some of the Android parts. It's pretty simple. A basic one (that works in most of my cases) looks like the following. I have a comment in this block, it will allow me to specify the version name and code when generating the APK.

build.gradle

apply plugin: "android"
android {
        compileSdkVersion 17
        /*
        defaultConfig {
            versionCode = 1
            versionName = "0.0.0"
        }
        */
    }

Something we are going to want to add, to help out anyone that hasn't seen the light of Gradle yet, a way for them to use the project without installing it.

build.gradle

task wrapper(type: org.gradle.api.tasks.wrapper.Wrapper) {
    gradleVersion = '1.4'
}

So now we have one project to build. Now we are going to add the others. I put them in a directory, maybe call it deps, or subProjects. It doesn't really matter, but you will need to know where you put it. To tell Gradle where the projects are you are going to need to add them to the settings.gradle.

Directory Structure:

Project Root
+-- src (see above)
+-- subProjects (where projects are held)
|   +-- reallyCoolProject1 (your first included project)
|       \-- See project structure for a normal app
|   \-- reallyCoolProject2 (your second included project)
|       \-- See project structure for a normal app
+-- build.gradle
\-- settings.gradle

settings.gradle:

include ':subProjects:reallyCoolProject1'
include ':subProjects:reallyCoolProject2'

The last thing you should make sure of is the subProjects/reallyCoolProject1/build.gradle has apply plugin: "android-library" instead of apply plugin: "android".

Like every Gradle project (and Maven) we now need to tell the root project about it's dependency. This can also include any normal Java dependencies that you want.

build.gradle

dependencies{
    compile 'com.fasterxml.jackson.core:jackson-core:2.1.4'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.1.4'
    compile project(":subProjects:reallyCoolProject1")
    compile project(':subProjects:reallyCoolProject2')
}

I know this seems like a lot of steps, but they are pretty easy once you do it once or twice. This way will also allow you to build on a CI server assuming you have the Android SDK installed there.

NDK Side Note: If you are going to use the NDK you are going to need something like below. Example build.gradle file can be found here: https://gist.github.com/khernyo/4226923

build.gradle

task copyNativeLibs(type: Copy) {
    from fileTree(dir: 'libs', include: '**/*.so' )  into  'build/native-libs'
}
tasks.withType(Compile) { compileTask -> compileTask.dependsOn copyNativeLibs }

clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
  pkgTask.jniDir new File('build/native-libs')
}

I don't Know you use any Bootstrap version but the useful helper class for centering and block an element in center it is .center-block because this class contain margin and display CSS properties but the .text-center class only contain the text-align property

Bootstrap Helper Class center-block

netstat -l (assuming it comes with that version of UNIX)

The SSPI context error definitely indicates authentication is being attempted using Kerberos.

Since Kerberos authentication SQL Server's Windows Authentication relies on Active Directory, which requires a thrusted relationship between your computer and your network domain controller, you should start by validating that relationship.

You can quickly check that relationship, thru the following Powershell command Test-ComputerSecureChannel.

Test-ComputerSecureChannel -verbose

If it returns False, you must repair your computer Active Directory secure channel, since without it no domain credencials validation is possible outside your computer.

You can repair your Computer Secure Channel, thru the following Powershell command:

Test-ComputerSecureChannel -Repair

Check the security event logs, if you are using kerberos you should see logon attempts with authentication package: Kerberos.

The NTLM authentication may be failing and so a kerberos authentication attempt is being made. You might also see an NTLM logon attempt failure in your security event log?

You can turn on kerberos event logging in dev to try to debug why the kerberos is failing, although it is very verbose.

Microsoft's Kerberos Configuration Manager for SQL Server may help you quickly diagnose and fix this issue.

Here is a good story to read: http://houseofbrick.com/microsoft-made-an-easy-button-for-spn-and-double-hop-issues/

I think what you are looking for may be

int fsync(int fd);

or

int fdatasync(int fd);

fsync will flush the file from kernel buffer to the disk. fdatasync will also do except for the meta data.

How about running many instances of your application. If crashes are due to random memory bit changes, chances are some of your app instances will make it through and produce accurate results. It's probably quite easy (for someone with statistical background) to calculate how many instances do you need given bit flop probability to achieve as tiny overall error as you wish.

I don't know what your string is, but I'm going to assume that it manages its own memory.

You have two solutions:

1: Return a struct which contains all the types you need.

struct Tuple {
    int a;
    string b;
};

struct Tuple getPair() {
    Tuple r = { 1, getString() };
    return r;
}

void foo() {
    struct Tuple t = getPair();
}

2: Use pointers to pass out values.

void getPair(int* a, string* b) {
    // Check that these are not pointing to NULL
    assert(a);
    assert(b);
    *a = 1;
    *b = getString();
}

void foo() {
    int a, b;
    getPair(&a, &b);
}

Which one you choose to use depends largely on personal preference as to whatever semantics you like more.

This works using grep without needing to use perl or find.

grep -rli 'old-word' * | xargs -i@ sed -i 's/old-word/new-word/g' @

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

For both Python 2 and 3:

import six

six.next(six.itervalues(d))

A possible solutions is to declare a second bean which reads from the same properties file:

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="/WEB-INF/app.properties" />
</bean> 

<util:properties id="appProperties" location="classpath:/WEB-INF/app.properties"/>

The bean named 'appProperties' is of type java.util.Properties and can be dependency injected using the @Resource attruibute shown above.

This way worked for me when adding random data to MySql table using a python script.
First install the following packages using the below commands

pip install mysql-connector-python<br>
pip install random

import mysql.connector
import random

from datetime import date


start_dt = date.today().replace(day=1, month=1).toordinal()
end_dt = date.today().toordinal()

mydb = mysql.connector.connect(
    host="localhost",
    user="root",
    password="root",
    database="your_db_name"
)

mycursor = mydb.cursor()

sql_insertion = "INSERT INTO customer (name,email,address,dateJoined) VALUES (%s, %s,%s, %s)"
#insert 10 records(rows)
for x in range(1,11):
    #generate a random date
    random_day = date.fromordinal(random.randint(start_dt, end_dt))
    value = ("customer" + str(x),"customer_email" + str(x),"customer_address" + str(x),random_day)
    mycursor.execute(sql_insertion , value)

mydb.commit()

print("customer records inserted!")

Following is a sample output of the insertion

cid       |  name      |  email           |    address        |  dateJoined  |

1         | customer1  |  customer_email1 | customer_address1 |  2020-11-15  |
2         | customer2  |  customer_email2 | customer_address2 |  2020-10-11  |
3         | customer3  |  customer_email3 | customer_address3 |  2020-11-17  |
4         | customer4  |  customer_email4 | customer_address4 |  2020-09-20  |
5         | customer5  |  customer_email5 | customer_address5 |  2020-02-18  |
6         | customer6  |  customer_email6 | customer_address6 |  2020-01-11  |
7         | customer7  |  customer_email7 | customer_address7 |  2020-05-30  |
8         | customer8  |  customer_email8 | customer_address8 |  2020-04-22  |
9         | customer9  |  customer_email9 | customer_address9 |  2020-01-05  |
10        | customer10 |  customer_email10| customer_address10|  2020-11-12  |

A function returns a value and a procedure just executes commands.

The name function comes from math. It is used to calculate a value based on input.

A procedure is a set of command which can be executed in order.

In most programming languages, even functions can have a set of commands. Hence the difference is only in the returning a value part.

But if you like to keep a function clean, (just look at functional languages), you need to make sure a function does not have a side effect.

It can be done with excellent py-spy. It's a sampling profiler for Python programs, so its job is to attach to a Python processes and sample their call stacks. Hence, py-spy dump --pid $SOME_PID is all you need to do to dump call stacks of all threads in the $SOME_PID process. Typically it needs escalated privileges (to read the target process' memory).

Here's an example of how it looks like for a threaded Python application.

$ sudo py-spy dump --pid 31080
Process 31080: python3.7 -m chronologer -e production serve -u www-data -m

While not yet supported on iOS (as of iOS 10), websites can send push notifications to Firefox and Chrome (Desktop/Android) with the Push API.

The Push API is used in conjunction with the older Web Notifications to display the message. The advantage is that the Push API allow the notification to be delivered even when the user is not surfing your website, because they are built upon Service Workers (scripts that are registered by the browser and can be executed in background at a later time even after your user has left your website).

The process of sending a notification involves the following:

1. a user visits your website (must be secured over HTTPS): you ask permission to display push notifications and you register a service worker (a script that will be executed when a push notification is received)
2. if the user has granted permission, you can read the device token (endpoint) which should be sent to the server and stored
3. now you can send notifications to the user: your server makes an HTTP POST request to the endpoint (which is an URL that contains the device token). The server which receives the request is owned by the browser manufacturer (e.g. Google, Mozilla): the browser is constantly connected to it and can read the incoming notifications.
4. when the user browser receives a notification executes the service worker, which is responsible for managing the event, retrieving the notification data from the server and displaying the notification to the user

The Push API is currently supported on desktop and Android by Chrome, Firefox and Opera.

You can also send push notifications to Apple / Safari desktop using APNs. The approach is similar, but with many complications (apple developer certificates, push packages, low-level TCP connection to APNs).

If you want to implement the push notifications by yourself start with these tutorials:

• Push API: Push Notifications on the Open Web
• Apple Push Notification system: Configuring Safari Push Notifications

If you are looking for a drop in solution I would suggest Pushpad, which is a service I have built.

Update (September 2017): Apple has started developing the service workers for WebKit (status). Since the service workers are a fundamental technology for web push, this is a big step forward.

I just checked it in MySQL 5.7 and am really surprised how no one offered a simple answer: NATURAL JOIN

When the tables or (select outcome) have IDENTICAL columns, you can use NATURAL JOIN as a way to find intersection:

For example:

table1:

id, name, jobid

'1', 'John', '1'

'2', 'Jack', '3'

'3', 'Adam', '2'

'4', 'Bill', '6'

table2:

id, name, jobid

'1', 'John', '1'

'2', 'Jack', '3'

'3', 'Adam', '2'

'4', 'Bill', '5'

'5', 'Max', '6'

And here is the query:

SELECT * FROM table1 NATURAL JOIN table2;

Query Result: id, name, jobid

'1', 'John', '1'

'2', 'Jack', '3'

'3', 'Adam', '2'

Note: In react you can put javascript expression inside curly bracket. We can use this property in this example.
Note: give one look to below example:

class LoginForm extends React.Component {

  constructor(props) {
    super(props);

    this.state = {i:1};
  }

  handleClick() {
    this.setState(prevState => ({i : prevState.i + 1}));

    console.log(this.state.j);  
  }


  render() {

    return (
      <div>
        <p onClick={this.handleClick.bind(this)}>Click to change image</p>
        <img src={'images/back'+ this.state.i+'.jpg'}/>
      </div>
      );

  }
}

Another alternative , might not work in all enviroments.Atleast assured it works in nodejs 0.8 This approach uses a non standard way of modifying the internal proto prop

function myError(msg){ 
      var e = new Error(msg); 
      _this = this; 
      _this.__proto__.__proto__ = e;
}

plt.show() should come after plt.savefig()

Explanation: plt.show() clears the whole thing, so anything afterwards will happen on a new empty figure

Given the html below:

<button class="btn-without-border"> Submit </button>

In the css style do the following:

.btn-without-border:focus {
    border: none;
    outline: none;
}

This code will remove button border and will disable button border focus when the button is clicked.

It happens that /etc/hosts file doesn't support wild card entries.

You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf and add the following line:

address=/example.com/127.0.0.1

To throw in another solution that has no need for subclassing:

UITextField *txtField = [UITextField new];
txtField.borderStyle = UITextBorderStyleRoundedRect;

// grab BG layer
CALayer *bgLayer = txtField.layer.sublayers.lastObject;
bgLayer.opacity = 0.f;

// add new bg view
UIView *bgView = [UIView new];
bgView.backgroundColor = [UIColor whiteColor];
bgView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
bgView.userInteractionEnabled = NO;

[txtField addSubview: bgView];
[txtField sendSubviewToBack: bgView];

Tested with iOS 7 and iOS 8. Both working. Still there might be the chance of Apple modifying the UITextField's layer hierarchy screwing up things badly.

You can do this using generic SQL with group by:

SELECT C.Content_ID, C.Content_Title, MAX(M.Media_Id)
FROM tbl_Contents C LEFT JOIN
     tbl_Media M
     ON M.Content_Id = C.Content_Id 
GROUP BY C.Content_ID, C.Content_Title
ORDER BY MAX(C.Content_DatePublished) ASC;

Or with a correlated subquery:

SELECT C.Content_ID, C.Contt_Title,
       (SELECT M.Media_Id
        FROM tbl_Media M
        WHERE M.Content_Id = C.Content_Id
        ORDER BY M.MEDIA_ID DESC
        LIMIT 1
       ) as Media_Id
FROM tbl_Contents C 
ORDER BY C.Content_DatePublished ASC;

Of course, the syntax for limit 1 varies between databases. Could be top. Or rownum = 1. Or fetch first 1 rows. Or something like that.

The HTML code is for three div align side by side and can be used for two also by some changes

<div id="wrapper">
  <div id="first">first</div>
  <div id="second">second</div>
  <div id="third">third</div>
</div>

The CSS will be

#wrapper {
  display:table;
  width:100%;
}
#row {
  display:table-row;
}
#first {
  display:table-cell;
  background-color:red;
  width:33%;
}
#second {
  display:table-cell;
  background-color:blue;
  width:33%;
}
#third {
  display:table-cell;
  background-color:#bada55;
  width:34%;
}

This code will workup towards responsive layout as it will resize the

<div> 

according to device width. Even one can silent anyone

<div>

as

<!--<div id="third">third</div> --> 

and can use rest two for two

<div> 

side by side.

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

The answers so far will work.. if you only want to use the height without padding, borders, etc.

If you would like to account for padding, borders, and margin, you should use .outerHeight.

var bottom = $('#bottom').position().top + $('#bottom').outerHeight(true);

This can be done for a normal subview inside a larger UIView, but it doesn't work automatically for headerViews. The height of a headerView is determined by what's returned by tableView:heightForHeaderInSection: so you have to calculate the height based on the height of the UILabel plus space for the UIButton and any padding you need. You need to do something like this:

-(CGFloat)tableView:(UITableView *)tableView 
          heightForHeaderInSection:(NSInteger)section {
    NSString *s = self.headeString[indexPath.section];
    CGSize size = [s sizeWithFont:[UIFont systemFontOfSize:17] 
                constrainedToSize:CGSizeMake(281, CGFLOAT_MAX)
                    lineBreakMode:NSLineBreakByWordWrapping];
    return size.height + 60;
}

Here headerString is whatever string you want to populate the UILabel, and the 281 number is the width of the UILabel (as setup in Interface Builder)

An NDF file is a user defined secondary database file of Microsoft SQL Server with an extension .ndf, which store user data. Moreover, when the size of the database file growing automatically from its specified size, you can use .ndf file for extra storage and the .ndf file could be stored on a separate disk drive. Every NDF file uses the same filename as its corresponding MDF file. We cannot open an .ndf file in SQL Server Without attaching its associated .mdf file.

I had this problem recently when I changed the development server for a project. I was getting this error on the line of code where I declared a new OracleConnection variable.

After trying many things, including installing hotfixes, I tried changing the references Oracle.DataAccess and System.Data.OracleClient in the project and it worked!

When a project is moved to a new machine, I suggest you renew all the references added in that project.

No need to calculate it manually.

Just use getGlobalVisibleRect like so:

Rect myViewRect = new Rect();
myView.getGlobalVisibleRect(myViewRect);
float x = myViewRect.left;
float y = myViewRect.top;

Also note that for the centre coordinates, rather than something like:

...
float two = (float) 2
float cx = myViewRect.left + myView.getWidth() / two;
float cy = myViewRect.top + myView.getHeight() / two;

You can just do:

float cx = myViewRect.exactCenterX();
float cy = myViewRect.exactCenterY();

CAST both fields to datatype DATE and you can use a minus:

(CAST(MAX(joindate) AS date) - CAST(MIN(joindate) AS date)) as DateDifference

Test case:

SELECT  (CAST(MAX(joindate) AS date) - CAST(MIN(joindate) AS date)) as DateDifference
FROM 
    generate_series('2014-01-01'::timestamp, '2014-02-01'::timestamp, interval '1 hour') g(joindate);

Result: 31

Or create a function datediff():

CREATE OR REPLACE FUNCTION datediff(timestamp, timestamp) 
RETURNS int 
LANGUAGE sql 
AS
$$
    SELECT CAST($1 AS date) - CAST($2 AS date) as DateDifference
$$;

Good. I suggest creating a Value Object (Vo) that contains the fields you need. The code is simpler, we do not change the functioning of Jackson and it is even easier to understand. Regards!

You can use fall-through method in switch case.

const x = 'Welcome';

switch (x) {
  case 'Come':
    console.log(1)
    break;

  case 'Welcome':
  case 'Wel':
  case 'come':
    console.log(2)
    break;

  case 'Wel':
    console.log(3)
    break;

  default:
    break;
}

To return a value from a VBScript function, assign the value to the name of the function, like this:

Function getNumber
    getNumber = "423"
End Function

2016 update:

You can create a new stacking context, as seen on Coderwall:

<div style="transform: translate3d(0,0,0);overflow:hidden">
   <img style="position:fixed; ..." />
</div>

Which refers to http://dev.w3.org/csswg/css-transforms/#transform-rendering

For elements whose layout is governed by the CSS box model, any value other than none for the transform results in the creation of both a stacking context and a containing block. The object acts as a containing block for fixed positioned descendants.

You can, if they are uploaded. Generally they are called "frameworkname-version-source(s)"

I would put the secondSet in a HashMap before the comparison. This way you will reduce the second list's search time to n(1). Like this:

HashMap<Integer,Record> hm = new HashMap<Integer,Record>(secondSet.size());
int i = 0;
for(Record secondRecord : secondSet){
    hm.put(i,secondRecord);
    i++;
}
for(Record firstRecord : firstSet){
    for(int i=0; i<secondSet.size(); i++){
    //use hm for comparison
    }
}

userIdeaUC = userIdea.substring(0, 1).toUpperCase() + userIdea.length() > 1 ? userIdea.substring(1) : "";

or

userIdeaUC = userIdea.substring(0, 1).toUpperCase();
if(userIdea.length() > 1)
   userIdeaUC += userIdea.substring(1);

The problem is the circular dependency between the modules. a imports b and b imports a. But one of them needs to be loaded first - in this case python ends up initializing module a before b and b.hi() doesn't exist yet when you try to access it in a.

Basically local variables aren't automatically initialized. Hence using them without initializing would result in an exception.

Only the following variables are automatically initialized to their default values:

• Static variables
• Instance variables of class and struct instances
• Array elements

The default values are as follows (assigned in default constructor of a class):

• The default value of a variable of reference type is null.
• For integer types, the default value is 0
• For char, the default value is `\u0000'
• For float, the default value is 0.0f
• For double, the default value is 0.0d
• For decimal, the default value is 0.0m
• For bool, the default value is false
• For an enum type, the default value is 0
• For a struct type, the default value is obtained by setting all value type fields to their default values

As far as later parts of your question are conerned:

• The reason why all variables which are not automatically initialized to default values should be initialized is a restriction imposed by compiler.
• private bool foo = false; This is indeed redundant since this is an instance variable of a class. Hence this would be initialized to false in the default constructor. Hence no need to set this to false yourself.

Some disadvantage of "INTERVAL '1' DAY" is that bind variables cannot be used for the number of days added. Instead, numtodsinterval can be used, like in this small example:

select trunc(sysdate) + numtodsinterval(:x, 'day') tag
from dual

You have to install libpq-dev/postgresql-libs, which is the header files and static library for compiling C programs to link with the libpq library in order to communicate with a PostgreSQL database backend.

On Arch this will run:

$ sudo pacman -S postgresql-libs

On Debian and Ubuntu:

$ sudo apt-get install libpq-dev

On Mac OS X:

$ brew install postgresql

On Red Hat/CentOS/Fedora:

$ sudo yum install postgresql-devel

Refreshing an old topic. I was able to achieve that my activity does not fold when the home button (physical or virtual) is pressed. Here is my code for activity onCreate() method:

super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_alarm_screen);
        context = getApplicationContext();
        int windowType;
        if (Build.VERSION.SDK_INT>=26) windowType = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
        else windowType = WindowManager.LayoutParams.TYPE_TOAST;
        final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                windowType,
                WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                        | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                        | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                        | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
                        | WindowManager.LayoutParams.FLAG_FULLSCREEN,
                PixelFormat.TRANSLUCENT
        );
        wm = (WindowManager) getApplicationContext()
                .getSystemService(Context.WINDOW_SERVICE);

        mTopView = (ViewGroup) getLayoutInflater().inflate(R.layout.activity_alarm_screen, null);
        getWindow().setAttributes(params);
        //Set up your views here
        testView = mTopView.findViewById(R.id.test);
        wm.addView(mTopView, params);

On API 26 and abovem you need to get screen overlay permission from the user. Tested on Android 7 and 8.

Here's a very simple, fast dplyr/tidy solution:

Remove rows that are entirely the same:

library(dplyr)
iris %>% 
  distinct(.keep_all = TRUE)

Remove rows that are the same only in certain columns:

iris %>% 
  distinct(Sepal.Length, Sepal.Width, .keep_all = TRUE)

Create a foreground service with the START_STICKY flag.

@Override
public int onStartCommand(Intent startIntent, int flags, int startId) {
   if (startIntent != null) {
       String action = startIntent.getAction();
       String command = startIntent.getStringExtra(CMD_NAME);
       if (ACTION_CMD.equals(action)) {
           if (CMD_PAUSE.equals(command)) {
               if (mPlayback != null && mPlayback.isPlaying()) {
                   handlePauseRequest();
               }
           } else if (CMD_PLAY.equals(command)) {
               ArrayList<Track> queue = new ArrayList<>();
               for (Parcelable input : startIntent.getParcelableArrayListExtra(ARG_QUEUE)) {
                   queue.add((Track) Parcels.unwrap(input));
               }
               int index = startIntent.getIntExtra(ARG_INDEX, 0);
               playWithQueue(queue, index);
           }
       }
   }

   return START_STICKY;
}

This can then be called from any activity to play some music

Intent intent = new Intent(MusicService.ACTION_CMD, fileUrlToPlay, activity, MusicService::class.java)
intent.putParcelableArrayListExtra(MusicService.ARG_QUEUE, tracks)
intent.putExtra(MusicService.ARG_INDEX, position)
intent.putExtra(MusicService.CMD_NAME, MusicService.CMD_PLAY)
activity.startService(intent)

You can bind to the service using bindService and to make the Service pause/stop from the corresponding activity lifecycle methods.

if you have repository for entity Foo and need to select all entries with exact string value boo (also works for other primitive types or entity types). Put this into your repository interface:

List<Foo> findByBoo(String boo);

if you need to order results:

List<Foo> findByBooOrderById(String boo);

You need to add a <meta> tag in your <head> containing name="theme-color", with your HEX code as the content value. For example:

<meta name="theme-color" content="#999999" />

Update:

If the android device has native dark-mode enabled, then this meta tag is ignored.

Chrome for Android does not use the color on devices with native dark-mode enabled.

If you do "docker attach "container id" you get into the container. To exit from the container without stopping the container you need to enter Ctrl+P+Q

None of this worked in my specific instance. What did was changing to a NetBIOS name from the FQDN.

Instead of:
\\server.domain.net\file.ps1
use:
\\server\file.ps1

Using the name bypasses the "automatically detect intranet network" config in IE.

Haha, Lovely - let me also include my version of stackPusher's code :). We are using this functionality in C#. Works fine for all Excel ranges.:

public static String ConvertToLiteral(int number)
{
        int firstLetter = (((number - 27) / (26 * 26))) % 26;
        int middleLetter = ((((number - 1) / 26)) % 26);

        int lastLetter = (number % 26);
        firstLetter = firstLetter == 0 ? 26 : firstLetter;
        middleLetter = middleLetter == 0 ? 26 : middleLetter;
        lastLetter = lastLetter == 0 ? 26 : lastLetter;
        String returnedString = "";
        returnedString = number > 27 * 26 ? (Convert.ToChar(firstLetter + 64).ToString()) : returnedString;
        returnedString += number > 26 ? (Convert.ToChar(middleLetter + 64).ToString()) : returnedString;
        returnedString += lastLetter >= 0 ? (Convert.ToChar(lastLetter + 64).ToString()) : returnedString;
        return returnedString;
}

Try the following:

select * From emp_master 
where emp_last_name= 
case emp_first_name 
 when 'test'    then 'test' 
 when 'Mr name' then 'name'
end

You can focus on a split window using # ctrl-ww.

for example, pressing:

1 ctrl-ww

would focus on the first window, usually being NERDTree.

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

For v4 this is a known issue that won't be addressed in 4.0 but there is a workaround. Check https://github.com/select2/select2/issues/2830

After digging through the PowerShell documentation, I discovered some useful information about this issue. You can't use the $args if you used the param(...) at the beginning of your file; instead you will need to use $PSBoundParameters. I copy/pasted your code into a PowerShell script, and it worked as you'd expect in PowerShell version 2 (I am not sure what version you were on when you ran into this issue).

If you are using $PSBoundParameters (and this ONLY works if you are using param(...) at the beginning of your script), then it is not an array, it is a hash table, so you will need to reference it using the key / value pair.

param($p1, $p2, $p3, $p4)
$Script:args=""
write-host "Num Args: " $PSBoundParameters.Keys.Count
foreach ($key in $PSBoundParameters.keys) {
    $Script:args+= "`$$key=" + $PSBoundParameters["$key"] + "  "
}
write-host $Script:args

And when called with...

PS> ./foo.ps1 a b c d

The result is...

Num Args:  4
$p1=a  $p2=b  $p3=c  $p4=d

You could implement a JavaScript block which contains a function with your needs.

<div style="position: absolute; left: 10px; top: 40px;"> 
    <img src="logg.png" width="114" height="38" onclick="DoSomething();" />
</div>

Edit

gulp-util is deprecated and should be avoid, so it's recommended to use minimist instead, which gulp-util already used.

So I've changed some lines in my gulpfile to remove gulp-util:

var argv = require('minimist')(process.argv.slice(2));

gulp.task('styles', function() {
  return gulp.src(['src/styles/' + (argv.theme || 'main') + '.scss'])
    …
});

Original

In my project I use the following flag:

gulp styles --theme literature

Gulp offers an object gulp.env for that. It's deprecated in newer versions, so you must use gulp-util for that. The tasks looks like this:

var util = require('gulp-util');

gulp.task('styles', function() {
  return gulp.src(['src/styles/' + (util.env.theme ? util.env.theme : 'main') + '.scss'])
    .pipe(compass({
        config_file: './config.rb',
        sass   : 'src/styles',
        css    : 'dist/styles',
        style  : 'expanded'

    }))
    .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9', 'ff 17', 'opera 12.1', 'ios 6', 'android 4'))
    .pipe(livereload(server))
    .pipe(gulp.dest('dist/styles'))
    .pipe(notify({ message: 'Styles task complete' }));
});

The environment setting is available during all subtasks. So I can use this flag on the watch task too:

gulp watch --theme literature

And my styles task also works.

Ciao Ralf

In C/C++ you have header files (*.H). There you declare your functions/classes. So for example you will have to #include "second.h" to your main.cpp file.

In second.h you just declare like this void yourFunction(); In second.cpp you implement it like

void yourFunction() { 
   doSomethng(); 
}

Don't forget to #include "second.h" also in the beginning of second.cpp

Hope this helps:)

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

Set

display: block;

on a and give some height

This is going to depend on your application but in general the fastest way to transpose a matrix would be to invert your coordinates when you do a look up, then you do not have to actually move any data.

You must to wrap your following code into a block (Either method or static).

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is your name?");
String name = in.readLine(); ;
System.out.println("Hello " + name);

Without a block you can only declare variables and more than that assign them a value in single statement.

For method main() will be best choice for now:

public class details {
    public static void main(String[] args){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or If you want to use static block then...

public class details {
    static {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or if you want to build another method then..

public class details {
    public static void main(String[] args){
        myMethod();
    }
    private static void myMethod(){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

Also worry about exception due to BufferedReader .

Also note that using the "foreach" method in the original question does have some limitations, such as not being able to remove items from the list during the iteration.

The new for-loop is easier to read and removes the need for a separate iterator, but is only really usable in read-only iteration passes.

Just in case you do this for a lot of functions in your class:

class Foo {
public:
  virtual void f1() {
    // ...
  }
  virtual void f2() {
    // ...
  }
  //...
};

class Bar : public Foo {
private:
  typedef Foo super;
public:
  void f1() {
    super::f1();
  }
};

This might save a bit of writing if you want to rename Foo.

How about this as a simple example:

SELECT Customer.Name, Customer.Address FROM Customer WHERE Customer.Name > "def"

vs.

SELECT Customers.Name, Customers.Address FROM Customers WHERE Customers.Name > "def"

The SQL in the latter is stranger sounding than the former.

I vote for singular.

Why not using: SELECT home, MAX(datetime) AS MaxDateTime,player,resource FROM topten GROUP BY home Did I miss something?

TL;DR: A service in ng6 with providedIn: "root" cannot find the ComponentFactory when the Component is not added in the entryComponents of app.module.

This problem can also occur if you are using angular 6 in combination with dynamically creating a Component in a service!

For example, creating an Overlay:

@Injectable({
  providedIn: "root"
})
export class OverlayService {

  constructor(private _overlay: Overlay) {}

  openOverlay() {
    const overlayRef = this._createOverlay();
    const portal = new ComponentPortal(OverlayExampleComponent);

    overlayRef.attach(portal).instance;
  }
}

The Problem is the

providedIn: "root"

definition, which provides this service in app.module.

So if your service is located in, for example, the "OverlayModule", where you also declared the OverlayExampleComponent and added it to the entryComponents, the service cannot find the ComponentFactory for OverlayExampleComponent.

$( "#myId option:selected" ).text(); will give you the text that you selected in the drop down element. either way you can change it to .val(); to get the value of it . check the below coding

<select id="myId">
    <option value="1">Mr</option>
    <option value="2">Mrs</option>
    <option value="3">Ms</option>`
    <option value="4">Dr</option>
    <option value="5">Prof</option>
</select>

If I understood your question, try something like this

declare @dd varchar(50)='Jan 30 2013 12:00:00:000AM'

Select convert(varchar,(CONVERT(date,@dd,103)),103)

Update

SELECT
PREFIX_TableName.ColumnName1 AS Name,
PREFIX_TableName.ColumnName2 AS E-Mail,
convert(varchar,(CONVERT(date,PREFIX_TableName.ColumnName3,103)),103) AS TransactionDate,
PREFIX_TableName.ColumnName4 AS OrderNumber

• Compiler : Which convert Human understandable format into machine understandable format
• Linker : Which convert machine understandable format into Operating system understandable format
• Loader : is entity which actually load and runs the program into RAM

Linker & Interpreter are mutually exclusive Interpreter getting code line by line and execute line by line.

With text files, maybe the EOF is -1 when using BufferReader.read(), char by char. I made a test with BufferReader.readLine()!=null and it worked properly.

This is a favorite interview question. With this questions, the interviewer tries to find out how well you understand the behavior of objects with respect to constructors, methods, class variables (static variables) and instance variables.

import java.util.ArrayList;
import java.util.List;

class Test {
    private final List foo;

    public Test() {
        foo = new ArrayList();
        foo.add("foo"); // Modification-1
    }

    public void setFoo(List foo) {
       //this.foo = foo; Results in compile time error.
    }
}

In the above case, we have defined a constructor for 'Test' and gave it a 'setFoo' method.

About constructor: Constructor can be invoked only one time per object creation by using the new keyword. You cannot invoke constructor multiple times, because constructor are not designed to do so.

About method: A method can be invoked as many times as you want (Even never) and the compiler knows it.

Scenario 1

private final List foo;  // 1

foo is an instance variable. When we create Test class object then the instance variable foo, will be copied inside the object of Test class. If we assign foo inside the constructor, then the compiler knows that the constructor will be invoked only once, so there is no problem assigning it inside the constructor.

If we assign foo inside a method, the compiler knows that a method can be called multiple times, which means the value will have to be changed multiple times, which is not allowed for a final variable. So the compiler decides constructor is good choice! You can assign a value to a final variable only one time.

Scenario 2

private static final List foo = new ArrayList();

foo is now a static variable. When we create an instance of Test class, foo will not be copied to the object because foo is static. Now foo is not an independent property of each object. This is a property of Test class. But foo can be seen by multiple objects and if every object which is created by using the new keyword which will ultimately invoke the Test constructor which changes the value at the time of multiple object creation (Remember static foo is not copied in every object, but is shared between multiple objects.)

Scenario 3

t.foo.add("bar"); // Modification-2

Above Modification-2 is from your question. In the above case, you are not changing the first referenced object, but you are adding content inside foo which is allowed. Compiler complains if you try to assign a new ArrayList() to the foo reference variable.
Rule If you have initialized a final variable, then you cannot change it to refer to a different object. (In this case ArrayList)

final classes cannot be subclassed
final methods cannot be overridden. (This method is in superclass)
final methods can override. (Read this in grammatical way. This method is in a subclass)

Campaign Monitor have an excellent support matrix detailing what's supported and what isn't among various mail clients.

You can use a service like Litmus to view how an email appears across several clients and whether they get caught by filters, etc.

In order to use my example,Your file "abc.txt" needs to look like:

[your-config]
path1 = "D:\test1\first"
path2 = "D:\test2\second"
path3 = "D:\test2\third"

Then in your software you can use the config parser:

import ConfigParser

and then in you code:

 configParser = ConfigParser.RawConfigParser()   
 configFilePath = r'c:\abc.txt'
 configParser.read(configFilePath)

Use case:

self.path = configParser.get('your-config', 'path1')

*Edit (@human.js)

in python 3, ConfigParser is renamed to configparser (as described here)

2D scatter plot

Using the scatter method of the matplotlib.pyplot module should work (at least with matplotlib 1.2.1 with Python 2.7.5), as in the example code below. Also, if you are using scatter plots, use scatterpoints=1 rather than numpoints=1 in the legend call to have only one point for each legend entry.

In the code below I've used random values rather than plotting the same range over and over, making all the plots visible (i.e. not overlapping each other).

import matplotlib.pyplot as plt
from numpy.random import random

colors = ['b', 'c', 'y', 'm', 'r']

lo = plt.scatter(random(10), random(10), marker='x', color=colors[0])
ll = plt.scatter(random(10), random(10), marker='o', color=colors[0])
l  = plt.scatter(random(10), random(10), marker='o', color=colors[1])
a  = plt.scatter(random(10), random(10), marker='o', color=colors[2])
h  = plt.scatter(random(10), random(10), marker='o', color=colors[3])
hh = plt.scatter(random(10), random(10), marker='o', color=colors[4])
ho = plt.scatter(random(10), random(10), marker='x', color=colors[4])

plt.legend((lo, ll, l, a, h, hh, ho),
           ('Low Outlier', 'LoLo', 'Lo', 'Average', 'Hi', 'HiHi', 'High Outlier'),
           scatterpoints=1,
           loc='lower left',
           ncol=3,
           fontsize=8)

plt.show()

3D scatter plot

To plot a scatter in 3D, use the plot method, as the legend does not support Patch3DCollection as is returned by the scatter method of an Axes3D instance. To specify the markerstyle you can include this as a positional argument in the method call, as seen in the example below. Optionally one can include argument to both the linestyle and marker parameters.

import matplotlib.pyplot as plt
from numpy.random import random
from mpl_toolkits.mplot3d import Axes3D

colors=['b', 'c', 'y', 'm', 'r']

ax = plt.subplot(111, projection='3d')

ax.plot(random(10), random(10), random(10), 'x', color=colors[0], label='Low Outlier')
ax.plot(random(10), random(10), random(10), 'o', color=colors[0], label='LoLo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[1], label='Lo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[2], label='Average')
ax.plot(random(10), random(10), random(10), 'o', color=colors[3], label='Hi')
ax.plot(random(10), random(10), random(10), 'o', color=colors[4], label='HiHi')
ax.plot(random(10), random(10), random(10), 'x', color=colors[4], label='High Outlier')

plt.legend(loc='upper left', numpoints=1, ncol=3, fontsize=8, bbox_to_anchor=(0, 0))

plt.show()

If you're dealing with natural language text and need to replace a word, not just part of a string, you have to add a pinch of regular expressions to your gsub as a plain text substitution can lead to disastrous results:

'mislocated cat, vindicating'.gsub('cat', 'dog')
=> "mislodoged dog, vindidoging"

Regular expressions have word boundaries, such as \b which matches start or end of a word. Thus,

'mislocated cat, vindicating'.gsub(/\bcat\b/, 'dog')
=> "mislocated dog, vindicating"

In Ruby, unlike some other languages like Javascript, word boundaries are UTF-8-compatible, so you can use it for languages with non-Latin or extended Latin alphabets:

'???? ? ??????, ??? ??????'.gsub(/\b????\b/, '?????')
=> "????? ? ??????, ??? ??????"

I am adding a second answer. I wrote a quick benchmarking script to try various methods here.

$arr = array(0 => 123456);
for($i = 1; $i < 500000; $i++) {
    $arr[$i] = rand(0,PHP_INT_MAX);
}

shuffle($arr);
$arr2 = $arr;
$arr3 = $arr;

/** 
 * Method 1 - array_search()
 */
$start = microtime(true);
while(($key = array_search(123456,$arr)) !== false) {
    unset($arr[$key]);
}
echo count($arr). ' left, in '.(microtime(true) - $start).' seconds<BR>';

/** 
 * Method 2 - basic loop
 */
$start = microtime(true);
foreach($arr2 as $k => $v) {
    if ($v == 123456) {
        unset($arr2[$k]);
    }
}
echo count($arr2). 'left, in '.(microtime(true) - $start).' seconds<BR>';

/** 
 * Method 3 - array_keys() with search parameter
 */
$start = microtime(true);
$keys = array_keys($arr3,123456);
foreach($keys as $k) {
    unset($arr3[$k]);
}
echo count($arr3). 'left, in '.(microtime(true) - $start).' seconds<BR>';

The third method, array_keys() with the optional search parameter specified, seems to be by far the best method. Output example:

499999 left, in 0.090957164764404 seconds
499999left, in 0.43156313896179 seconds
499999left, in 0.028877019882202 seconds

Judging by this, the solution I would use then would be:

$keysToRemove = array_keys($items,$id);
foreach($keysToRemove as $k) {
    unset($items[$k]);
}

Note, adding

$.support.cors = true;

was sufficient to force $.ajax calls to work on IE8

Add android:checked = "true" in your activity.xml

filter_by uses keyword arguments, whereas filter allows pythonic filtering arguments like filter(User.name=="john")

I had a similar challenge when writing a Powershell script to interact with AWS CLI using the AWS Powershell Tools

I ran the command:

Get-S3Bucket // List AWS S3 buckets

And then I got the error:

Get-S3Bucket : A positional parameter cannot be found that accepts argument list

Here's how I fixed it:

Get-S3Bucket does not accept // List AWS S3 buckets as an attribute.

I had put it there as a comment, but it's not acceptable by the AWS CLI as a comment. AWS CLI rather sees it as a parameter.

I had to do it this way:

#List AWS S3 buckets
Get-S3Bucket

That's all.

I hope this helps

Use the "MMMM" format specifier:

string month = dateTime.ToString("MMMM");

this works flawlessly for me. insert any code before or after the "do until" loop. In your case, put the 5 lines (time1= & time2= & "do until" loop) at the end inside your do loop

sub whatever()
Dim time1, time2

time1 = Now
time2 = Now + TimeValue("0:00:01")
    Do Until time1 >= time2
        DoEvents
        time1 = Now()
    Loop

End sub

I was using reactive forms and ran into similar problems. What helped me was to make sure that I set up a corresponding FormGroup in the class. Something like this:

myFormGroup: FormGroup = this.builder.group({
    dob: ['', Validators.required]
});

A pixel is the smallest unit value to render something with, but you can trick thickness with optical illusions by modifying colors (the eye can only see up to a certain resolution too).

Here is a test to prove this point:

div { border-color: blue; border-style: solid; margin: 2px; }

div.b1 { border-width: 1px; }
div.b2 { border-width: 0.1em; }
div.b3 { border-width: 0.01em; }
div.b4 { border-width: 1px; border-color: rgb(160,160,255); }

<div class="b1">Some text</div>
<div class="b2">Some text</div>
<div class="b3">Some text</div>
<div class="b4">Some text</div>

Output

Which gives the illusion that the last DIV has a smaller border width, because the blue border blends more with the white background.

Edit: Alternate solution

Alpha values may also be used to simulate the same effect, without the need to calculate and manipulate RGB values.

.container {
  border-style: solid;
  border-width: 1px;
  
  margin-bottom: 10px;
}

.border-100 { border-color: rgba(0,0,255,1); }
.border-75 { border-color: rgba(0,0,255,0.75); }
.border-50 { border-color: rgba(0,0,255,0.5); }
.border-25 { border-color: rgba(0,0,255,0.25); }

<div class="container border-100">Container 1 (alpha = 1)</div>
<div class="container border-75">Container 2 (alpha = 0.75)</div>
<div class="container border-50">Container 3 (alpha = 0.5)</div>
<div class="container border-25">Container 4 (alpha = 0.25)</div>

My activity calls finish() (which doesn't make it finish immediately, but will do eventually) and calls Google Street Viewer. When I debug it on Eclipse, my connection to the app breaks when Street Viewer is called, which I understand as the (whole) application being closed, supposedly to free up memory (as a single activity being finished shouldn't cause this behavior). Nevertheless, I'm able to save state in a Bundle via onSaveInstanceState() and restore it in the onCreate() method of the next activity in the stack. Either by using a static singleton or subclassing Application I face the application closing and losing state (unless I save it in a Bundle). So from my experience they are the same with regards to state preservation. I noticed that the connection is lost in Android 4.1.2 and 4.2.2 but not on 4.0.7 or 3.2.4, which in my understanding suggests that the memory recovery mechanism has changed at some point.

don't have to use grep either

an example:

sed -n '/searchwords/{s/^\(.\{12\}\).*/\1/g;p}' file

UPDATE will change only the columns you specifically list.

UPDATE some_table
SET field1='Value 1'
WHERE primary_key = 7;

The WHERE clause limits which rows are updated. Generally you'd use this to identify your table's primary key (or ID) value, so that you're updating only one row.

The SET clause tells MySQL which columns to update. You can list as many or as few columns as you'd like. Any that you do not list will not get updated.

Directly from the node.js tag wiki, make sure watch some of the talk videos linked there to get a better idea.

Node.js is an event based, asynchronous I/O framework that uses Google's V8 JavaScript Engine.

Node.js - or just Node as it's commonly called - is used for developing applications that make heavy use of the ability to run JavaScript both on the client, as well as on server side and therefore benefit from the re-usability of code and the lack of context switching.

It's also possible to use matured JavaScript frameworks like YUI and jQuery for server side DOM manipulation.

To ease the development of complex JavaScript further, Node.js supports the CommonJS standard that allows for modularized development and the distribution of software in packages via the Node Package Manager.

Applications that can be written using Node.js include, but are not limited to:

• Static file servers
• Web Application frameworks
• Messaging middle ware
• Servers for HTML5 multi player games

Session_unset(); only destroys the session variables. To end the session there is another function called session_destroy(); which also destroys the session .

update :

In order to kill the session altogether, like to log the user out, the session id must also be unset. If a cookie is used to propagate the session id (default behavior), then the session cookie must be deleted. setcookie() may be used for that

In JAVA, values like:

1. 8.5
2. 3.9
3. (and so on..)

Is assumed as double and not float.

You can also perform a cast in order to solve the problem:

float b = (float) 3.5;

Another solution:

float b = 3.5f;

There is also another convention, used by many open source projects including Spring.

interface User {
}

class DefaultUser implements User {
}

class AnotherClassOfUser implements User {
}

I personally do not like the "I" prefix for the simple reason that its an optional convention. So if I adopt this does IIOPConnection mean an interface for IOPConnection? What if the class does not have the "I" prefix, do I then know its not an interface..the answer here is no, because conventions are not always followed, and policing them will create more work that the convention itself saves.

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");

You can confirm this by printing out the string to see that it turns out identical to the first case.

Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string, which would make it look perhaps like this:

$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
               mysql_real_escape_string($prefix));
$query = mysql_query($sql);

Note that inside the first argument of sprintf the percent sign needs to be doubled to end up appearing once in the result.

I found this sample script here that seems to be working pretty well:

SELECT r.session_id,r.command,CONVERT(NUMERIC(6,2),r.percent_complete)
AS [Percent Complete],CONVERT(VARCHAR(20),DATEADD(ms,r.estimated_completion_time,GetDate()),20) AS [ETA Completion Time],
CONVERT(NUMERIC(10,2),r.total_elapsed_time/1000.0/60.0) AS [Elapsed Min],
CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0) AS [ETA Min],
CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0/60.0) AS [ETA Hours],
CONVERT(VARCHAR(1000),(SELECT SUBSTRING(text,r.statement_start_offset/2,
CASE WHEN r.statement_end_offset = -1 THEN 1000 ELSE (r.statement_end_offset-r.statement_start_offset)/2 END)
FROM sys.dm_exec_sql_text(sql_handle))) AS [SQL]
FROM sys.dm_exec_requests r WHERE command IN ('RESTORE DATABASE','BACKUP DATABASE')

If you're posting a json body, dont use the form parameter. Using form will make the arrays into field[0].attribute, field[1].attribute etc. Instead use body like so.

var jsonDataObj = {'mes': 'hey dude', 'yo': ['im here', 'and here']};
request.post({
    url: 'https://api.site.com',
    body: jsonDataObj,
    json: true
  }, function(error, response, body){
  console.log(body);
});

This error appears when you try to upload an apk that has same version values as the one already on playstore.

Just change the following in your build.gradle file => versionCode and versionName

defaultConfig {
    applicationId "com.my.packageId"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 2      <-- increment this by 1
    versionName "2.0"  <-- this is the version that shows up in playstore, 
                           remember that the versioning scheme goes as follows.
                           first digit = major breaking changes version
                           second digit = minor changes version
                           third digit = minor patches and bug fixes.
                           e.g versionName "2.0.1"
}

Seeing a user banging away at a control that overrides her decisions is a sad sight. Set the control's Enabled property to False. If you don't like that then change its Items property so only one item is selectable.

Use '!' before the pip:

! pip install opencv-python

The easy way to fix this is to add this to your form.

{{ csrf_field() }}
<input type="hidden" name="_method" value="PUT">

then the update method will be like this :

public function update(Request $request, $id)
{
    $project = Project::findOrFail($id);
    $project->name = $request->name;
    $project->description = $request->description;

    $post->save();
}

Check your SMTP settings in your php.ini file. Your host should have some documentation about what credentials to use. Perhaps you can check your error log file, it might have more information available.

REST is just a software architecture style for exposing resources.

• Use HTTP methods explicitly.
• Be stateless.
• Expose directory structure-like URIs.
• Transfer XML, JavaScript Object Notation (JSON), or both.

A typical REST call to return information about customer 34456 could look like:

http://example.com/customer/34456

Have a look at the IBM tutorial for REST web services

http://jqapi.com/ Traversing--> Tree Traversal --> Children

set ORACLE_SID=<YOUR_SID>

or maybe

shutdown abort;

or maybe

You can use this script to find dates between two dates. Reference taken from this Article:

DECLARE @StartDateTime DATETIME
DECLARE @EndDateTime DATETIME

SET @StartDateTime = '2015-01-01'
SET @EndDateTime = '2015-01-12';

WITH DateRange(DateData) AS 
(
    SELECT @StartDateTime as Date
    UNION ALL
    SELECT DATEADD(d,1,DateData)
    FROM DateRange 
    WHERE DateData < @EndDateTime
)
SELECT DateData
FROM DateRange
OPTION (MAXRECURSION 0)
GO

const char *one = "Hello ";
const char *two = "World";

string total( string(one) + two );

// to use the concatenation as const char*, use:
total.c_str()

Updated: changed string total = string(one) + string(two); to string total( string(one) + two ); for performance reasons (avoids construction of string two and temporary string total)

// string total(move(move(string(one)) + two));  // even faster?

WHY INTERFACE??????

It starts with a dog. In particular, a pug.

The pug has various behaviors:

public class Pug { 
private String name;
public Pug(String n) { name = n; } 
public String getName() { return name; }  
public String bark() { return  "Arf!"; } 
public boolean hasCurlyTail() { return true; } }

And you have a Labrador, who also has a set of behaviors.

public class Lab { 
private String name; 
public Lab(String n) { name = n; } 
public String getName() { return name; } 
public String bark() { return "Woof!"; } 
public boolean hasCurlyTail() { return false; } }

We can make some pugs and labs:

Pug pug = new Pug("Spot"); 
Lab lab = new Lab("Fido");

And we can invoke their behaviors:

pug.bark() -> "Arf!" 
lab.bark() -> "Woof!" 
pug.hasCurlyTail() -> true 
lab.hasCurlyTail() -> false 
pug.getName() -> "Spot"

Let's say I run a dog kennel and I need to keep track of all the dogs I'm housing. I need to store my pugs and labradors in separate arrays:

public class Kennel { 
Pug[] pugs = new Pug[10]; 
Lab[] labs = new Lab[10];  
public void addPug(Pug p) { ... } 
public void addLab(Lab l) { ... } 
public void printDogs() { // Display names of all the dogs } }

But this is clearly not optimal. If I want to house some poodles, too, I have to change my Kennel definition to add an array of Poodles. In fact, I need a separate array for each kind of dog.

Insight: both pugs and labradors (and poodles) are types of dogs and they have the same set of behaviors. That is, we can say (for the purposes of this example) that all dogs can bark, have a name, and may or may not have a curly tail. We can use an interface to define what all dogs can do, but leave it up to the specific types of dogs to implement those particular behaviors. The interface says "here are the things that all dogs can do" but doesn't say how each behavior is done.

public interface Dog 
{
public String bark(); 
public String getName(); 
public boolean hasCurlyTail(); }

Then I slightly alter the Pug and Lab classes to implement the Dog behaviors. We can say that a Pug is a Dog and a Lab is a dog.

public class Pug implements Dog {
// the rest is the same as before } 

public class Lab implements Dog { 
// the rest is the same as before 
}

I can still instantiate Pugs and Labs as I previously did, but now I also get a new way to do it:

Dog d1 = new Pug("Spot"); 
Dog d2 = new Lab("Fido");

This says that d1 is not only a Dog, it's specifically a Pug. And d2 is also a Dog, specifically a Lab. We can invoke the behaviors and they work as before:

d1.bark() -> "Arf!" 
d2.bark() -> "Woof!" 
d1.hasCurlyTail() -> true 
d2.hasCurlyTail() -> false 
d1.getName() -> "Spot"

Here's where all the extra work pays off. The Kennel class become much simpler. I need only one array and one addDog method. Both will work with any object that is a dog; that is, objects that implement the Dog interface.

public class Kennel {
Dog[] dogs = new Dog[20]; 
public void addDog(Dog d) { ... } 
public void printDogs() {
// Display names of all the dogs } }

Here's how to use it:

Kennel k = new Kennel(); 
Dog d1 = new Pug("Spot"); 
Dog d2 = new Lab("Fido"); 
k.addDog(d1); 
k.addDog(d2); 
k.printDogs();

The last statement would display: Spot Fido

An interface give you the ability to specify a set of behaviors that all classes that implement the interface will share in common. Consequently, we can define variables and collections (such as arrays) that don't have to know in advance what kind of specific object they will hold, only that they'll hold objects that implement the interface.

To extend Ted Cambron's answer above and something that hasn't been addressed here: If you remove all line breaks indiscriminately from a chunk of entered text, you will end up with paragraphs running into each other without spaces when you output that text later. This is what I use:

sub cleanLines{

    my $text = shift;

    $text =~ s/\r/ /; #replace \r with space
    $text =~ s/\n/ /; #replace \n with space
    $text =~ s/  / /g; #replace double-spaces with single space

    return $text;
}

The last substitution uses the g 'greedy' modifier so it continues to find double-spaces until it replaces them all. (Effectively substituting anything more that single space)

To quote the jasmine github project,

expect(x).toEqual(y); compares objects or primitives x and y and passes if they are equivalent

expect(x).toBe(y); compares objects or primitives x and y and passes if they are the same object

This seems to be the canonical reference point for high-level database interaction in Python: http://wiki.python.org/moin/HigherLevelDatabaseProgramming

From there, it looks like Dejavu implements Martin Fowler's DataMapper pattern fairly abstractly in Python.

I made a sample WebApp in May 2012 that uses JDO 3.0 & DataNucleus 3.0 - take a look how clean it is: https://github.com/TorbenVesterager/BadAssWebApp

Okay maybe it's a little bit too clean, because I use the POJOs both for the database and the JSON client, but it's fun :)

If you're using the org.apache.poi.ss.usermodel (not HSSF or XSSF) you can use:

style.setBorderBottom(BorderStyle.THIN);
style.setBorderTop(BorderStyle.THIN);
style.setBorderLeft(BorderStyle.THIN);
style.setBorderRight(BorderStyle.THIN);

all the border styles are here at the apache documentation

A couple of quick notes:

• It's "length" not "lenght"
• Table aliases in your query would probably make it a lot more readable

Now onto the problem...

You need to explicitly convert your parameters to VARCHAR before trying to concatenate them. When SQL Server sees @my_int + 'X' it thinks you're trying to add the number "X" to @my_int and it can't do that. Instead try:

SET @ActualWeightDIMS =
     CAST(@Actual_Dims_Lenght AS VARCHAR(16)) + 'x' +
     CAST(@Actual_Dims_Width  AS VARCHAR(16)) + 'x' +
     CAST(@Actual_Dims_Height  AS VARCHAR(16))

Reformat affects the whole source code and may rebreak your lines, while Correct Indentation only affects the whitespace at the beginning of the lines.

I think you want $data[$category] = $question;

Or in case you want an array that maps categories to array of questions:

$data = array();
foreach($file_data as $value) {
    list($category, $question) = explode('|', $value, 2);

    if(!isset($data[$category])) {
        $data[$category] = array();
    }
    $data[$category][] = $question;
}
print_r($data);

Thanks Cody, that was very helpful. I've just added an example for guys using the Delegate Command in C#

            // Get Password as Binding not supported for control-type PasswordBox
            LoginPassword = ((PasswordBox) args).Password;

            // Rest of code here
        });
   }
}

This is along the lines of Lawrence Wenham's answer, but depending on your use case, it may or may not be an improvement -- you don't need the setters.

public interface IPerson {
  int GetAge();
  string GetName();
}

public interface IGetPerson {
  IPerson GetPerson();
}

public static class IGetPersonAdditions {
  public static int GetAgeViaPerson(this IGetPerson getPerson) { // I prefer to have the "ViaPerson" in the name in case the object has another Age property.
    IPerson person = getPerson.GetPersion();
    return person.GetAge();
  }
  public static string GetNameViaPerson(this IGetPerson getPerson) {
    return getPerson.GetPerson().GetName();
  }
}

public class Person: IPerson, IGetPerson {
  private int Age {get;set;}
  private string Name {get;set;}
  public IPerson GetPerson() {
    return this;
  }
  public int GetAge() {  return Age; }
  public string GetName() { return Name; }
}

Now any object that knows how to get a person can implement IGetPerson, and it will automatically have the GetAgeViaPerson() and GetNameViaPerson() methods. From this point, basically all Person code goes into IGetPerson, not into IPerson, other than new ivars, which have to go into both. And in using such code, you don't have to be concerned about whether or not your IGetPerson object is itself actually an IPerson.

If the entire site uses HTTPS, your sessionId cookie is as secure as the HTTPS encryption at the very least. This is because cookies are sent as HTTP headers, and when using SSL, the HTTP headers are encrypted using the SSL when being transmitted.

Another possible solution is to create your own custom Image view(say RotateableImageView extends ImageView )...and override the onDraw() to rotate either the canvas/bitmaps before redering on to the canvas.Don't forget to restore the canvas back.

But if you are going to rotate only a single instance of image view,your solution should be good enough.

To change width is not that hard. Just remove the width attribute from the tag and add width: 100%; in the css for #canvas

#canvas{
  border: solid 1px blue;  
  width: 100%;
}

Changing height is a bit harder: you need javascript. I have used jQuery because i'm more comfortable with.

you need to remove the height attribute from the canvas tag and add this script:

  <script>
  function resize(){    
    $("#canvas").outerHeight($(window).height()-$("#canvas").offset().top- Math.abs($("#canvas").outerHeight(true) - $("#canvas").outerHeight()));
  }
  $(document).ready(function(){
    resize();
    $(window).on("resize", function(){                      
        resize();
    });
  });
  </script>

You can see this fiddle: https://jsfiddle.net/1a11p3ng/3/

EDIT:

To answer your second question. You need javascript

0) First of all i changed your #border id into a class since ids must be unique for an element inside an html page (you can't have 2 tags with the same id)

.border{
  border: solid 1px black;
}

#canvas{
  border: solid 1px blue;  
  width: 100%;
}

1) Changed your HTML to add ids where needed, two inputs and a button to set the values

<div class="row">
  <div class="col-xs-2 col-sm-2 border">content left</div>
  <div class="col-xs-6 col-sm-6 border" id="main-content">
    <div class="row">
      <div class="col-xs-6">
        Width <input id="w-input" type="number" class="form-control">
      </div>
      <div class="col-xs-6">
        Height <input id="h-input" type="number" class="form-control">
      </div>
      <div class="col-xs-12 text-right" style="padding: 3px;">
        <button id="set-size" class="btn btn-primary">Set</button>
      </div> 
    </div>
    canvas
    <canvas id="canvas"></canvas>

  </div>
  <div class="col-xs-2 col-sm-2 border">content right</div>
</div>

2) Set the canvas height and width so that it fits inside the container

$("#canvas").outerHeight($(window).height()-$("#canvas").offset().top-Math.abs( $("#canvas").outerHeight(true) - $("#canvas").outerHeight()));

3) Set the values of the width and height forms

$("#h-input").val($("#canvas").outerHeight());
$("#w-input").val($("#canvas").outerWidth());

4) Finally, whenever you click on the button you set the canvas width and height to the values set. If the width value is bigger than the container's width then it will resize the canvas to the container's width instead (otherwise it will break your layout)

    $("#set-size").click(function(){
        $("#canvas").outerHeight($("#h-input").val());
        $("#canvas").outerWidth(Math.min($("#w-input").val(), $("#main-content").width()));
    });

See a full example here https://jsfiddle.net/1a11p3ng/7/

UPDATE 2:

To have full control over the width you can use this:

<div class="container-fluid">
<div class="row">
  <div class="col-xs-2 border">content left</div>
  <div class="col-xs-8 border" id="main-content">
    <div class="row">
      <div class="col-xs-6">
        Width <input id="w-input" type="number" class="form-control">
      </div>
      <div class="col-xs-6">
        Height <input id="h-input" type="number" class="form-control">
      </div>
      <div class="col-xs-12 text-right" style="padding: 3px;">
        <button id="set-size" class="btn btn-primary">Set</button>
      </div> 
    </div>
      canvas
    <canvas id="canvas">

    </canvas>

  </div>
  <div class="col-xs-2 border">content right</div>
</div>
</div>
  <script>
   $(document).ready(function(){
    $("#canvas").outerHeight($(window).height()-$("#canvas").offset().top-Math.abs( $("#canvas").outerHeight(true) - $("#canvas").outerHeight()));
    $("#h-input").val($("#canvas").outerHeight());
    $("#w-input").val($("#canvas").outerWidth());
    $("#set-size").click(function(){
        $("#canvas").outerHeight($("#h-input").val());
      $("#main-content").width($("#w-input").val());
      $("#canvas").outerWidth($("#main-content").width());
    });
   });
  </script>

the content left and content right columns will move above and belove the central div if the width is too high, but this can't be helped if you are using bootstrap. This is not, however, what responsive means. a truly responsive site will adapt its size to the user screen to keep the layout as you have intended without any external input, letting the user set any size which may break your layout does not mean making a responsive site.

DisplacedAussie's answer is correct, but usually a shorter method is just to reverse the single axis in question:

plt.scatter(x_arr, y_arr)
ax = plt.gca()
ax.set_ylim(ax.get_ylim()[::-1])

where the gca() function returns the current Axes instance and the [::-1] reverses the list.

Following single line of code will avoid the duplicate rows of a DataTable:

dataTable.DefaultView.ToTable(true, "employeeid");

Where:

• first parameter in ToTable() is a boolean which indicates whether you want distinct rows or not.

• second parameter in the ToTable() is the column name based on which we have to select distinct rows. Only these columns will be in the returned datatable.

The same can be done from a DataSet, by accessing a specific DataTable:

dataSet.Tables["Employee"].DefaultView.ToTable(true, "employeeid");

Open a new worksheet on the related instance (Alt-F10) and run the following query

SELECT view_name, owner
FROM sys.all_views 
ORDER BY owner, view_name

No guarantee, but I suspect IE uses the older Protected Storage API.

Please consider using some code like this:

SqlDataReader reader = command.ExecuteReader();
int numRows = 0;
DataTable dt = new DataTable();

dt.Load(reader);
numRows = dt.Rows.Count;

string attended_type = "";

for (int index = 0; index < numRows; index++)
{
    attended_type = dt.Rows[indice2]["columnname"].ToString();
}

reader.Close();

The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.

The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.

The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.

Edit: Also worth a look - kashif's comment about json-streamer and Henrik Heino's comment about bigjson.

You can retrieve bitmap from uri like this

Bitmap bitmap = null;
try {
    bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
} catch (IOException e) {
    e.printStackTrace();
}

git mv moves the file, updating the index to record the replaced file path, as well as updating any affected git submodules. Unlike a manual move, it also detects case-only renames that would not otherwise be detected as a change by git.

It is similar (though not identical) in behavior to moving the file externally to git, removing the old path from the index using git rm, and adding the new one to the index using git add.

Answer Motivation

This question has a lot of great partial answers. This answer is an attempt to combine them into a single cohesive answer. Additionally, one thing not called out by any of the other answers is the fact that the man page actually does mostly answer the question, but it's perhaps less obvious than it could be.

Detailed Explanation

Three different effects are called out in the man page:

1. The file, directory, or symlink is moved in the filesystem:

   git-mv - Move or rename a file, a directory, or a symlink

2. The index is updated, adding the new path and removing the previous one:

   The index is updated after successful completion, but the change must still be committed.

3. Moved submodules are updated to work at the new location:

   Moving a submodule using a gitfile (which means they were cloned with a Git version 1.7.8 or newer) will update the gitfile and core.worktree setting to make the submodule work in the new location. It also will attempt to update the submodule.<name>.path setting in the gitmodules(5) file and stage that file (unless -n is used).

As mentioned in this answer, git mv is very similar to moving the file, adding the new path to the index, and removing the previous path from the index:

mv oldname newname
git add newname
git rm oldname

However, as this answer points out, git mv is not strictly identical to this in behavior. Moving the file via git mv adds the new path to the index, but not any modified content in the file. Using the three individual commands, on the other hand, adds the entire file to the index, including any modified content. This could be relevant when using a workflow which patches the index, rather than adding all changes in the file.

Additionally, as mentioned in this answer and this comment, git mv has the added benefit of handling case-only renames on file systems that are case-insensitive but case-preserving, as is often the case in current macOS and Windows file systems. For example, in such systems, git would not detect that the file name has changed after moving a file via mv Mytest.txt MyTest.txt, whereas using git mv Mytest.txt MyTest.txt would successfully update its name.

If you are starting the python interpreter from a shell on Linux or similar systems (BSD, not sure about Mac), you should also check the default encoding for the shell.

Call locale charmap from the shell (not the python interpreter) and you should see

[user@host dir] $ locale charmap
UTF-8
[user@host dir] $ 

If this is not the case, and you see something else, e.g.

[user@host dir] $ locale charmap
ANSI_X3.4-1968
[user@host dir] $ 

Python will (at least in some cases such as in mine) inherit the shell's encoding and will not be able to print (some? all?) unicode characters. Python's own default encoding that you see and control via sys.getdefaultencoding() and sys.setdefaultencoding() is in this case ignored.

If you find that you have this problem, you can fix that by

[user@host dir] $ export LC_CTYPE="en_EN.UTF-8"
[user@host dir] $ locale charmap
UTF-8
[user@host dir] $ 

(Or alternatively choose whichever keymap you want instead of en_EN.) You can also edit /etc/locale.conf (or whichever file governs the locale definition in your system) to correct this.

This error can happen because some MFC library (eg. mfc120.dll) from which the DLL is dependent is missing in windows/system32 folder.

It sounds like you just want a copy of the source code. If so why not just copy the directory and exclude the .git directory from the copy?

You could store this into a temporary table.

So instead of doing the CTE/sub query you would use a temp table.

Good article on these here http://codingsight.com/introduction-to-temporary-tables-in-sql-server/

If you want to pursue a "simple" solution, you might find this class I put together useful:

http://www.architectshack.com/TextFileEncodingDetector.ashx

It does the BOM detection automatically first, and then tries to differentiate between Unicode encodings without BOM, vs some other default encoding (generally Windows-1252, incorrectly labelled as Encoding.ASCII in .Net).

As noted above, a "heavier" solution involving NCharDet or MLang may be more appropriate, and as I note on the overview page of this class, the best is to provide some form of interactivity with the user if at all possible, because there simply is no 100% detection rate possible!

There are many realizations of hash functions written in JS. For example:

• SHA-1: http://www.webtoolkit.info/javascript-sha1.html
• SHA-256: http://www.webtoolkit.info/javascript-sha256.html
• MD5: http://www.webtoolkit.info/javascript-md5.html

If you don't need security, you can also use base64 which is not hash-function, has not fixed output and could be simply decoded by user, but looks more lightweight and could be used for hide values: http://www.webtoolkit.info/javascript-base64.html

If you are using PHP you can get it this way:

<?php
    $dbname = 'base.db';
    $db = new SQLite3($dbname);
    $sturturequery = $db->query("SELECT sql FROM sqlite_master WHERE name='foo'");

    $table = $sturturequery->fetchArray();
    echo '<pre>' . $table['sql'] . '</pre>';

    $db->close();
?>

Actually adding any header field to the NSURLRequest argument in shouldStartLoadWithRequest seems to work, because the request responds to setValue:ForHTTPHeaderField - but it doesn't actually work - the request is sent out without the header.

So I used this workaround in shouldStartLoadWithRequest which just copies the given request to a new mutable request, and re-loads it. This does in fact modify the header which is sent out.

if ( [request valueForHTTPHeaderField:@"MyUserAgent"] == nil )
{
    NSMutableURLRequest *modRequest = [request mutableCopyWithZone:NULL];
    [modRequest setValue:@"myagent" forHTTPHeaderField:@"MyUserAgent"];
    [webViewArgument loadRequest:modRequest];
    return NO;
}

Unfortunately, this still doesn't allow overriding the user-agent http header, which is apparently overwritten by Apple. I guess for overriding it you would have to manage a NSURLConnection by yourself.

You probably can't. Here's something that comes close. You won't get content to flow around it if there's space below.

Starting with Python 3, raw_input() was renamed to input().

From What’s New In Python 3.0, Builtins section second item.

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

You can simply add another join like this:

SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data 
    INNER JOIN dashboard_messages 
        ON dashboard_message_id = dashboard_messages.id
    INNER JOIN images
        ON dashboard_messages.image_id = images.image_id 

However be aware that, because it is an INNER JOIN, if you have a message without an image, the entire row will be skipped. If this is a possibility, you may want to do a LEFT OUTER JOIN which will return all your dashboard messages and an image_filename only if one exists (otherwise you'll get a null)

SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data 
    INNER JOIN dashboard_messages 
        ON dashboard_message_id = dashboard_messages.id
    LEFT OUTER JOIN images
        ON dashboard_messages.image_id = images.image_id

May be you are using this checking :

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
}

To resolve this you need to import android.provider.DocumentsContract class.

To resolve this issue you'll need to set the build SDK version to 19 (4.4) or higher to have API level 19 symbols available while compiling.

First, use the SDK Manager to download API 19 if you don't have it yet. Then, configure your project to use API 19:

• In Android Studio: File -> Project Structure -> General Settings -> Project SDK.
• In Eclipse ADT: Project Properties -> Android -> Project Build Target

Thanks .

You could use the ngSwitch directive:

  <div ng-switch on="selection" >
    <div ng-switch-when="settings">Settings Div</div>
    <span ng-switch-when="home">Home Span</span>
    <span ng-switch-default>default</span>
  </div>

If you don't want the DOM to be loaded with empty divs, you need to create your custom directive using $http to load the (sub)templates and $compile to inject it in the DOM when a certain condition has reached.

This is just an (untested) example. It can and should be optimized:

HTML:

<conditional-template ng-model="element" template-url1="path/to/partial1" template-url2="path/to/partial2"></div>

Directive:

app.directive('conditionalTemplate', function($http, $compile) {
   return {
      restrict: 'E',
      require: '^ngModel',
      link: function(sope, element, attrs, ctrl) {
        // get template with $http
        // check model via ctrl.$viewValue
        // compile with $compile
        // replace element with element.replaceWith()
      }
   };
});

I written in main activity like this,

override fun onSupportNavigateUp(): Boolean {
        return findNavController(R.id.my_nav_host_fragment).navigateUp(appBarConfiguration)
    }   

tomcat-maven-plugin in test

Tomcat usually does not add classes in src/test/java to the classpath. They are missing if you run tomcat in scope test. To order tomcat to respect classes in test, use -Dmaven.tomcat.useTestClasspath=true or add

<properties>
   <maven.tomcat.useTestClasspath>true</maven.tomcat.useTestClasspath>
</properties>

To your pom.xml.

<%: DateTime.Today.ToShortDateString() %>

Try this:

select sum(a), sum(b), sum(c)

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);

Simple and understandable

It is not possible to use the VOLUME instruction to tell docker what to mount. That would seriously break portability. This instruction tells docker that content in those directories does not go in images and can be accessed from other containers using the --volumes-from command line parameter. You have to run the container using -v /path/on/host:/path/in/container to access directories from the host.

Mounting host volumes during build is not possible. There is no privileged build and mounting the host would also seriously degrade portability. You might want to try using wget or curl to download whatever you need for the build and put it in place.

var result = decimal.ToDouble(decimal.Divide(5, 2));

If someone is using Sequel the migration would look something like:

add_column :products, :price, "decimal(8,2)"

somehow Sequel ignores :precision and :scale

(Sequel Version: sequel (3.39.0, 3.38.0))

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

You can also use file_put_contents():

file_put_contents('ids.txt', implode("\n", $gemList) . "\n", FILE_APPEND);

You can use regexp grep for finding + second grep for highlight

echo "some123_string_and_another" | grep -o -P '.{0,3}string.{0,4}' | grep string

23_string_and
