Probably the exact details of em.flush() are implementation-dependent. In general anyway, JPA providers like Hibernate can cache the SQL instructions they are supposed to send to the database, often until you actually commit the transaction. For example, you call em.persist(), Hibernate remembers it has to make a database INSERT, but does not actually execute the instruction until you commit the transaction. Afaik, this is mainly done for performance reasons.

In some cases anyway you want the SQL instructions to be executed immediately; generally when you need the result of some side effects, like an autogenerated key, or a database trigger.

What em.flush() does is to empty the internal SQL instructions cache, and execute it immediately to the database.

Bottom line: no harm is done, only you could have a (minor) performance hit since you are overriding the JPA provider decisions as regards the best timing to send SQL instructions to the database.

@Entity(name = "someThing") => this name will be used to name the Entity
@Table(name = "someThing")  => this name will be used to name a table in DB

So, in the first case your table and entity will have the same name, that will allow you to access your table with the same name as the entity while writing HQL or JPQL.

And in second case while writing queries you have to use the name given in @Entity and the name given in @Table will be used to name the table in the DB.

So in HQL your someThing will refer to otherThing in the DB.

1. Entities are managed by javax.persistence.EntityManager instance using persistence context.
2. Each EntityManager instance is associated with a persistence context.
3. Within the persistence context, the entity instances and their lifecycle are managed.
4. Persistence context defines a scope under which particular entity instances are created, persisted, and removed.
5. A persistence context is like a cache which contains a set of persistent entities , So once the transaction is finished, all persistent objects are detached from the EntityManager's persistence context and are no longer managed.

The JPA @Column Annotation

The nullable attribute of the @Column annotation has two purposes:

• it's used by the schema generation tool
• it's used by Hibernate during flushing the Persistence Context

Schema Generation Tool

The HBM2DDL schema generation tool translates the @Column(nullable = false) entity attribute to a NOT NULL constraint for the associated table column when generating the CREATE TABLE statement.

As I explained in the Hibernate User Guide, it's better to use a tool like Flyway instead of relying on the HBM2DDL mechanism for generating the database schema.

Persistence Context Flush

When flushing the Persistence Context, Hibernate ORM also uses the @Column(nullable = false) entity attribute:

new Nullability( session ).checkNullability( values, persister, true );

If the validation fails, Hibernate will throw a PropertyValueException, and prevents the INSERT or UPDATE statement to be executed needesly:

if ( !nullability[i] && value == null ) {
    //check basic level one nullablilty
    throw new PropertyValueException(
            "not-null property references a null or transient value",
            persister.getEntityName(),
            persister.getPropertyNames()[i]
        );    
}

The Bean Validation @NotNull Annotation

The @NotNull annotation is defined by Bean Validation and, just like Hibernate ORM is the most popular JPA implementation, the most popular Bean Validation implementation is the Hibernate Validator framework.

When using Hibernate Validator along with Hibernate ORM, Hibernate Validator will throw a ConstraintViolation when validating the entity.

I fixed the issue by changing the code to

@Basic(optional = false)
@Column(name = "LastTouched", insertable = false, updatable = false)
@Temporal(TemporalType.TIMESTAMP)
private Date lastTouched;

So the timestamp column is ignored when generating SQL inserts. Not sure if this is the best way to go about this. Feedback is welcome.

I disagree with the selected answer, and as davidxxx correctly pointed out, getReference does not provide such behaviour of dynamic updations without select. I asked a question concerning the validity of this answer, see here - cannot update without issuing select on using setter after getReference() of hibernate JPA.

I quite honestly haven't seen anybody who's actually used that functionality. ANYWHERE. And i don't understand why it's so upvoted.

Now first of all, no matter what you call on a hibernate proxy object, a setter or a getter, an SQL is fired and the object is loaded.

But then i thought, so what if JPA getReference() proxy doesn't provide that functionality. I can just write my own proxy.

Now, we can all argue that selects on primary keys are as fast as a query can get and it's not really something to go to great lengths to avoid. But for those of us who can't handle it due to one reason or another, below is an implementation of such a proxy. But before i you see the implementation, see it's usage and how simple it is to use.

USAGE

Order example = ProxyHandler.getReference(Order.class, 3);
example.setType("ABCD");
example.setCost(10);
PersistenceService.save(example);

And this would fire the following query -

UPDATE Order SET type = 'ABCD' and cost = 10 WHERE id = 3;

and even if you want to insert, you can still do PersistenceService.save(new Order("a", 2)); and it would fire an insert as it should.

IMPLEMENTATION

Add this to your pom.xml -

<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>3.2.10</version>
</dependency>

Make this class to create dynamic proxy -

@SuppressWarnings("unchecked")
public class ProxyHandler {

public static <T> T getReference(Class<T> classType, Object id) {
    if (!classType.isAnnotationPresent(Entity.class)) {
        throw new ProxyInstantiationException("This is not an entity!");
    }

    try {
        Enhancer enhancer = new Enhancer();
        enhancer.setSuperclass(classType);
        enhancer.setCallback(new ProxyMethodInterceptor(classType, id));
        enhancer.setInterfaces((new Class<?>[]{EnhancedProxy.class}));
        return (T) enhancer.create();
    } catch (Exception e) {
        throw new ProxyInstantiationException("Error creating proxy, cause :" + e.getCause());
    }
}

Make an interface with all the methods -

public interface EnhancedProxy {
    public String getJPQLUpdate();
    public HashMap<String, Object> getModifiedFields();
}

Now, make an interceptor which will allow you to implement these methods on your proxy -

import com.anil.app.exception.ProxyInstantiationException;
import javafx.util.Pair;
import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;

import javax.persistence.Id;
import java.lang.reflect.Field;
import java.lang.reflect.Method;
import java.util.*;
/**

public class ProxyMethodInterceptor implements MethodInterceptor, EnhancedProxy {

private Object target;
private Object proxy;
private Class classType;
private Pair<String, Object> primaryKey;
private static HashSet<String> enhancedMethods;

ProxyMethodInterceptor(Class classType, Object id) throws IllegalAccessException, InstantiationException {
    this.classType = classType;
    this.target = classType.newInstance();
    this.primaryKey = new Pair<>(getPrimaryKeyField().getName(), id);
}

static {
    enhancedMethods = new HashSet<>();
    for (Method method : EnhancedProxy.class.getDeclaredMethods()) {
        enhancedMethods.add(method.getName());
    }
}

@Override
public Object intercept(Object obj, Method method, Object[] args, MethodProxy proxy) throws Throwable {
    //intercept enhanced methods
    if (enhancedMethods.contains(method.getName())) {
        this.proxy = obj;
        return method.invoke(this, args);
    }
    //else invoke super class method
    else
        return proxy.invokeSuper(obj, args);
}

@Override
public HashMap<String, Object> getModifiedFields() {
    HashMap<String, Object> modifiedFields = new HashMap<>();
    try {
        for (Field field : classType.getDeclaredFields()) {

            field.setAccessible(true);

            Object initialValue = field.get(target);
            Object finalValue = field.get(proxy);

            //put if modified
            if (!Objects.equals(initialValue, finalValue)) {
                modifiedFields.put(field.getName(), finalValue);
            }
        }
    } catch (Exception e) {
        return null;
    }
    return modifiedFields;
}

@Override
public String getJPQLUpdate() {
    HashMap<String, Object> modifiedFields = getModifiedFields();
    if (modifiedFields == null || modifiedFields.isEmpty()) {
        return null;
    }
    StringBuilder fieldsToSet = new StringBuilder();
    for (String field : modifiedFields.keySet()) {
        fieldsToSet.append(field).append(" = :").append(field).append(" and ");
    }
    fieldsToSet.setLength(fieldsToSet.length() - 4);
    return "UPDATE "
            + classType.getSimpleName()
            + " SET "
            + fieldsToSet
            + "WHERE "
            + primaryKey.getKey() + " = " + primaryKey.getValue();
}

private Field getPrimaryKeyField() throws ProxyInstantiationException {
    for (Field field : classType.getDeclaredFields()) {
        field.setAccessible(true);
        if (field.isAnnotationPresent(Id.class))
            return field;
    }
    throw new ProxyInstantiationException("Entity class doesn't have a primary key!");
}
}

And the exception class -

public class ProxyInstantiationException extends RuntimeException {
public ProxyInstantiationException(String message) {
    super(message);
}

A service to save using this proxy -

@Service
public class PersistenceService {

@PersistenceContext
private EntityManager em;

@Transactional
private void save(Object entity) {
    // update entity for proxies
    if (entity instanceof EnhancedProxy) {
        EnhancedProxy proxy = (EnhancedProxy) entity;
        Query updateQuery = em.createQuery(proxy.getJPQLUpdate());
        for (Entry<String, Object> entry : proxy.getModifiedFields().entrySet()) {
            updateQuery.setParameter(entry.getKey(), entry.getValue());
        }
        updateQuery.executeUpdate();
    // insert otherwise
    } else {
        em.persist(entity);
    }

}
}

We are currently using protobuf-java-format to convert our Protobuf messages (anything subclass of Message) into a JSON format to send over our web API.

Simply do:

  JsonFormat.printToString(protoMessage)

• See the Hibernate Forum for a explanation of the subtle differences between persist and save. It looks like the difference is the time the INSERT statement is ultimately executed. Since save does return the identifier, the INSERT statement has to be executed instantly regardless of the state of the transaction (which generally is a bad thing). Persist won't execute any statements outside of the currently running transaction just to assign the identifier. Save/Persist both work on transient instances, ie instances which have no identifier assigned yet and as such are not saved in the DB.

• Update and Merge both work on detached instances, ie instances which have a corresponding entry in the DB but which are currently not attached to (or managed by) a Session. The difference between them are what happens to the instance which is passed to the function. update tries to reattach the instance, that means that there must be no other instance of the persistent entity attached to the Session right now, otherwise an exception is thrown. merge, however, just copies all values to a persistent instance in the Session (which will be loaded if it is not currently loaded). The input object is not changed. So merge is more general than update, but may use more resources.

The question has been answered already, but just wanted to post a tip that was holding me up. This exception was being thrown after previous errors. I was getting this:

property toplink.platform.class.name is deprecated, property toplink.target-database should be used instead.

Even though I had changed the persistence.xml to include the new property name:

<property name="toplink.target-database" value="oracle.toplink.platform.database.oracle.Oracle10Platform"/>

Following the message about the deprecated property name I was getting the same PersistenceException like above and a whole other string of exceptions. My tip: make sure to check the beginning of the exception sausage.

There seems to be a bug in Glassfish v2.1.1 where redeploys or undeploys and deploys are not updating the persistence.xml, which is being cached somewhere. I had to restart the server and then it worked.

I had the same problem. I found the tutorial Hibernate One-To-One Mapping Example using Foreign key Annotation and followed it step by step like below:

Create database table with this script:

create table ADDRESS (
   id INT(11) NOT NULL AUTO_INCREMENT,
   street VARCHAR(250) NOT NULL,
   city  VARCHAR(100) NOT NULL,
   country  VARCHAR(100) NOT NULL,
   PRIMARY KEY (id)
);

create table STUDENT (
    id            INT(11) NOT NULL AUTO_INCREMENT, 
    name          VARCHAR(100) NOT NULL, 
    entering_date DATE NOT NULL, 
    nationality   TEXT NOT NULL, 
    code          VARCHAR(30) NOT NULL,
    address_id INT(11) NOT NULL,
    PRIMARY KEY (id),
    CONSTRAINT student_address FOREIGN KEY (address_id) REFERENCES ADDRESS (id)   
);

Here is the entities with the above tables

@Entity
@Table(name = "STUDENT")
public class Student implements Serializable {

    private static final long serialVersionUID = 6832006422622219737L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

 }

@Entity
@Table(name = "ADDRESS")
public class Address {

    @Id @GeneratedValue
    @Column(name = "ID")
    private long id;
}

The problem was resolved.

Notice: The primary key must be set to AUTO_INCREMENT

Problem seems to be associated with the SET statement. I think the expression can't be more than 4,000 bytes in size. There is no need to make any changes to any settings if all you are trying to do is to assign a dynamically generated statement that is more than 4,000 characters. What you need to do is to split your assignment. If your statement is 6,000 characters long, find a logical break point and then concatenate second half to the same variable. For example:

SET @Query = 'SELECT ....' [Up To 4,000 characters, then rest of statement as below]

SET @Query = @Query + [rest of statement]

Now run your query as normal i.e. EXEC ( @Query )

switch($someString.ToLower()) 
{ 
    {($_ -eq "y") -or ($_ -eq "yes")} { "You entered Yes." } 
    default { "You entered No." } 
}

Try Request.Url.Query if you want the raw querystring as a string.

It's pretty late to write this answer, but I thought of including it anyhow. String.prototype now has a method includes which can check for substring. This method is case sensitive.

var str = 'It was a good date';
console.log(str.includes('good')); // shows true
console.log(str.includes('Good')); // shows false

To check for a substring, the following approach can be taken:

if (mainString.toLowerCase().includes(substringToCheck.toLowerCase())) {
    // mainString contains substringToCheck
}

Check out the documentation to know more.

If you set the text state, why not use that directly?

_handlePress(event) {
  var username=this.state.text;

Of course the variable naming could be more descriptive than 'text' but your call.

If you are making the boolean column as not null then the default 'default' value is false; you don't have to explicitly specify it.

Your question is very poorly worded. Your code (sort of) already does what you want. What exactly are you confused about? x.numpy() answer the original title of your question:

Pytorch tensor to numpy array

you need improve your question starting with your title.

Anyway, just in case this is useful to others. You might need to call detach for your code to work. e.g.

RuntimeError: Can't call numpy() on Variable that requires grad.

So call .detach(). Sample code:

# creating data and running through a nn and saving it

import torch
import torch.nn as nn

from pathlib import Path
from collections import OrderedDict

import numpy as np

path = Path('~/data/tmp/').expanduser()
path.mkdir(parents=True, exist_ok=True)

num_samples = 3
Din, Dout = 1, 1
lb, ub = -1, 1

x = torch.torch.distributions.Uniform(low=lb, high=ub).sample((num_samples, Din))

f = nn.Sequential(OrderedDict([
    ('f1', nn.Linear(Din,Dout)),
    ('out', nn.SELU())
]))
y = f(x)

# save data
y.numpy()
x_np, y_np = x.detach().cpu().numpy(), y.detach().cpu().numpy()
np.savez(path / 'db', x=x_np, y=y_np)

print(x_np)

cpu goes after detach. See: https://discuss.pytorch.org/t/should-it-really-be-necessary-to-do-var-detach-cpu-numpy/35489/5

Also I won't make any comments on the slicking since that is off topic and that should not be the focus of your question. See this:

Understanding slice notation

Define versionName in AndroidManifest.xml

android:versionName="5.1.5"

Inside android{...} block in build.gradle of app level :

defaultConfig {
        applicationId "com.example.autoincrement"
        minSdkVersion 18
        targetSdkVersion 23
        multiDexEnabled true
        def version = getIncrementationVersionName()
        versionName version
}

Outside android{...} block in build.gradle of app level :

def getIncrementedVersionName() {
    List<String> runTasks = gradle.startParameter.getTaskNames();

    //find version name in manifest
    def manifestFile = file('src/main/AndroidManifest.xml')
    def matcher = Pattern.compile('versionName=\"(\\d+)\\.(\\d+)\\.(\\d+)\"').matcher(manifestFile.getText())
    matcher.find()

    //extract versionName parts
    def firstPart = Integer.parseInt(matcher.group(1))
    def secondPart = Integer.parseInt(matcher.group(2))
    def thirdPart = Integer.parseInt(matcher.group(3))

    //check is runTask release or not
    // if release - increment version
    for (String item : runTasks) {
        if (item.contains("assemble") && item.contains("Release")) {
            thirdPart++
            if (thirdPart == 10) {
                thirdPart = 0;
                secondPart++
                if (secondPart == 10) {
                    secondPart = 0;
                    firstPart++
                }
            }
        }
    }

    def versionName = firstPart + "." + secondPart + "." + thirdPart

    // update manifest
    def manifestContent = matcher.replaceAll('versionName=\"' + versionName + '\"')
    manifestFile.write(manifestContent)

    println "incrementVersionName = " + versionName

    return versionName
}

After create singed APK :

android:versionName="5.1.6"

Note : If your versionName different from my, you need change regex and extract parts logic.

From iOS 7 there is an API and you can get (and set) the tint color with:

self.view.tintColor

Or if you need the CGColor:

self.view.tintColor.CGColor

If self could be nil in the closure use [weak self].

If self will never be nil in the closure use [unowned self].

The Apple Swift documentation has a great section with images explaining the difference between using strong, weak, and unowned in closures:

https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/AutomaticReferenceCounting.html

• getattr(x, 'y') is equivalent to x.y
• setattr(x, 'y', v) is equivalent to x.y = v
• delattr(x, 'y') is equivalent to del x.y

What about switch case instead of if-else

  render() {
    switch (this.state.route) {
      case 'loginRoute':
        return (
            <Login changeRoute={this.changeRoute}
              changeName={this.changeName}
              changeRole={this.changeRole} />
        );
      case 'adminRoute':
        return (
            <DashboardAdmin
              role={this.state.role}
              name={this.state.name}
              changeRoute={this.changeRoute}
            />
        );
      default: 
        return <></>;
    }

JSON

An alternative Solution could be converting your list in the JSON format and print the Json-String. The advantage is a well formatted and readable Object-String without a need of implementing the toString(). Additionaly it works for any other Object or Collection on the fly.

Example using Google's Gson:

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

...
public static void printJsonString(Object o) {
    GsonBuilder gsonBuilder = new GsonBuilder();
    /*
     * Some options for GsonBuilder like setting dateformat or pretty printing
     */
    Gson gson = gsonBuilder.create();
    String json= gson.toJson(o);
    System.out.println(json);
}

You can also use a circle as a marker icon, for example:

var oMarker = new google.maps.Marker({
    position: latLng,
    sName: "Marker Name",
    map: map,
    icon: {
        path: google.maps.SymbolPath.CIRCLE,
        scale: 8.5,
        fillColor: "#F00",
        fillOpacity: 0.4,
        strokeWeight: 0.4
    },
});

and then, if you want to change the marker dynamically (like on mouseover), you can, for example:

oMarker.setIcon({
            path: google.maps.SymbolPath.CIRCLE,
            scale: 10,
            fillColor: "#00F",
            fillOpacity: 0.8,
            strokeWeight: 1
        })

You can set custom git aliases using git's config. Here's the syntax:

git config --global alias.<aliasName> "<git command>"

For example, if you need an alias to display a list of files which have merge conflicts, run:

git config --global alias.conflicts "diff --name-only --diff-filter=U"

Now you can use the above command only using "conflicts":

git conflicts
# same as running: git diff --name-only --diff-filter=U

You would need to always consider the state of all checkboxes!

You could increase or decrease a number on checking or unchecking, but imagine the site loads with three of them checked.

So you always need to check all of them:

<script type="text/javascript">
<!--
function showMe (it, box) {
  // consider all checkboxes with same name
  var checked = amountChecked(box.name);

  var vis = (checked >= 3) ? "block" : "none";
  document.getElementById(it).style.display = vis;
}

function amountChecked(name) {
  var all = document.getElementsByName(name);

  // count checked
  var result = 0;
  all.forEach(function(el) {
    if (el.checked) result++;
  });

  return result;
}
//-->
</script>

its very simple... 1.Download and put ur custom font in assets..then write one separate class for text view as follows: here i used futura font

public class CusFntTextView extends TextView {

public CusFntTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init();
}

public CusFntTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}

public CusFntTextView(Context context) {
    super(context);
    init();
}

private void init() {
    if (!isInEditMode()) {
        Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "Futura.ttf");
        setTypeface(tf);
    }
}

}

and do the following in xml :

 <com.packagename.CusFntTextView
        android:id="@+id/tvtitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"         
        android:text="Hi Android"           
        android:textAppearance="?android:attr/textAppearanceLarge"
      />

I have a latin version of the code of Razvan Dumitru because us use a million indicator even. Offcourse I use a double replace :D

public static string CleanNumb(string numb) 
{
    foreach (char c in ".,'´")
       numb = numb.Replace(c, ' ');

    return numb.Replace(" ", "");
}

I've come across a good article about designing Android apps UI for different screen resolutions, and I'd like to leave it here just for somebody searching in this area. Yes, I know that it's somehow described in Google docs (and mentioned in the posts above), I read that but it was not good for me (yeah, I may be too stupid)). It remained unclear for me how to design layouts capable to handle different screen size. I hate DP concept and so on, when I need to implement a "flexible" UI layout for different screens. (Hey iOS developers - yes, you're right it's Storyboard concept).

Android has not bad UI concept, but lacks iOS Storyboard features, unfortunately. Designing flexible UI in Android is not easy thing (at the best).

Here goes the article that helped me to understand what to do in Android to make layouts for different screen sizes:

JMSTUDIO Blog :- Decide Android App Screen Size

How to Design UI for Android Apps for Different Screen Size

To design an app UI for different screen sizes, our initial design has to meet a minimum required space for each screen size. Android defines a minimum size (in dp) for each generalized screen type. Here is an Android screen size guideline. When we get the screen size in dp, it is not enough for us to design the Android app UI. For each screen size, we need to prepare graphics and bitmap images for each density. Here is an Android screen density guideline.

For easy calculation, we can follow the 3:4:6:8 scaling ratio between the four generalized densities. If we create a 36×36 pixel picture for ldpi device, the rest densities pictures size will be 48×48 for mdpi, 72×72 for hdpi, and 96×96 for xhdpi.

How to Design Android Apps UI in Photoshop

Many designers have problems for designing Android app UI in photoshop or other pixel based graphic design tools because of density-independent unit, dp. Designers don’t know how to map dp to pixel. Google also doesn’t give a clear Android UI design guide for them, though they give a basic formula for dp and pixel translation.

As Android’s definition, 1pd equal to 1px under 160 dpi device (mdpi). So we want to design an Android app for xlarge Android device with mdpi density, we can define our UI size in pixel as 960 pixel in width and 720px in height; Follow the same mapping rule, we can get following Android App screen size UI design guideline:

I met this issue due to operation system, simple to different platform about JRE implementation.

new SecureRandom(key.getBytes())

will get the same value in Windows, while it's different in Linux. So in Linux need to be changed to

SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
secureRandom.setSeed(key.getBytes());
kgen.init(128, secureRandom);

"SHA1PRNG" is the algorithm used, you can refer here for more info about algorithms.

This one was beyond helpful for me, especially for matching multiple things that include new lines, every single other answer ended up just grouping all of the matches together.

Compiler :it is a system software which correct the error of programs,object file ,messages etc

Linker:it is a system software which combines One or more objectfiles and possible some library code into either some exicutable some library or a list of error

Loader: A program which loads the executable file to the primary memory of the machine

Not sure if you are coding these programs, but this is a simple example of how you'd do it.

program1.c

#include <stdio.h>
int main (int argc, char * argv[] ) {
    printf("%s", argv[1]); 
    return 0;
}

rgx.cpp

#include <cstdio>
#include <regex>
#include <iostream>
using namespace std;
int main (int argc, char * argv[] ) {
    char input[200];
    fgets(input,200,stdin);
    string s(input)
    smatch m;
    string reg_exp(argv[1]);
    regex e(reg_exp);
    while (regex_search (s,m,e)) {
      for (auto x:m) cout << x << " ";
      cout << endl;
      s = m.suffix().str();
    }
    return 0;
}

Compile both then run program1.exe "this subject has a submarine as a subsequence" | rgx.exe "\b(sub)([^ ]*)"

The | operator simply redirects the output of program1's printf operation from the stdout stream to the stdin stream whereby it's sitting there waiting for rgx.exe to pick up.

When you float those two divs, the content div collapses to zero height. Just add

<br style="clear:both;"/>

after the #right div but inside the content div. That will force the content div to surround the two internal, floating divs.

Using docker compose you can mount a volume with postgresql.auto.conf. Example:

version: '2'

services:
  db:
    image: postgres:10.9-alpine
    volumes:
      - postgres:/var/lib/postgresql/data:z
      - ./docker/postgres/postgresql.auto.conf:/var/lib/postgresql/data/postgresql.auto.conf
    ports:
      - 5432:5432

I needed a simple boolean to work with. Because it's undefined of not present, and not false, I use the !! to convert to boolean:

var hasTimer = !!$("#dataTable").data('timer');
if( hasTimer ){ /* ....... */ }

An alternative solution would be using filter:

if( $("#dataTable").filter('[data-timer]').length!==0) { /* ....... */ }

From your feature branch (e.g configUpdate) run:

git fetch
git rebase origin/master

Or the shorter form:

git pull --rebase

Why this works:

• git merge branchname takes new commits from the branch branchname, and adds them to the current branch. If necessary, it automatically adds a "Merge" commit on top.

• git rebase branchname takes new commits from the branch branchname, and inserts them "under" your changes. More precisely, it modifies the history of the current branch such that it is based on the tip of branchname, with any changes you made on top of that.

• git pull is basically the same as git fetch; git merge origin/master.

• git pull --rebase is basically the same as git fetch; git rebase origin/master.

So why would you want to use git pull --rebase rather than git pull? Here's a simple example:

• You start working on a new feature.

• By the time you're ready to push your changes, several commits have been pushed by other developers.

• If you git pull (which uses merge), your changes will be buried by the new commits, in addition to an automatically-created merge commit.

• If you git pull --rebase instead, git will fast forward your master to upstream's, then apply your changes on top.

What you need is:

if (!File.Exists(@"c:\test\Test\SomeFile.txt")) {
    File.Move(@"c:\test\SomeFile.txt", @"c:\test\Test\SomeFile.txt");
}

or

if (File.Exists(@"c:\test\Test\SomeFile.txt")) {
    File.Delete(@"c:\test\Test\SomeFile.txt");
}
File.Move(@"c:\test\SomeFile.txt", @"c:\test\Test\SomeFile.txt");

This will either:

• If the file doesn't exist at the destination location, successfully move the file, or;
• If the file does exist at the destination location, delete it, then move the file.

Edit: I should clarify my answer, even though it's the most upvoted! The second parameter of File.Move should be the destination file - not a folder. You are specifying the second parameter as the destination folder, not the destination filename - which is what File.Move requires. So, your second parameter should be c:\test\Test\SomeFile.txt.

Like the other answers said, sp_reset_connection indicates that connection pool is being reused. Be aware of one particular consequence!

Jimmy Mays' MSDN Blog said:

sp_reset_connection does NOT reset the transaction isolation level to the server default from the previous connection's setting.

UPDATE: Starting with SQL 2014, for client drivers with TDS version 7.3 or higher, the transaction isolation levels will be reset back to the default.

ref: SQL Server: Isolation level leaks across pooled connections

Here is some additional information:

What does sp_reset_connection do?

Data access API's layers like ODBC, OLE-DB and System.Data.SqlClient all call the (internal) stored procedure sp_reset_connection when re-using a connection from a connection pool. It does this to reset the state of the connection before it gets re-used, however nowhere is documented what things get reset. This article tries to document the parts of the connection that get reset.

sp_reset_connection resets the following aspects of a connection:

• All error states and numbers (like @@error)

• Stops all EC's (execution contexts) that are child threads of a parent EC executing a parallel query

• Waits for any outstanding I/O operations that is outstanding

• Frees any held buffers on the server by the connection

• Unlocks any buffer resources that are used by the connection

• Releases all allocated memory owned by the connection

• Clears any work or temporary tables that are created by the connection

• Kills all global cursors owned by the connection

• Closes any open SQL-XML handles that are open

• Deletes any open SQL-XML related work tables

• Closes all system tables

• Closes all user tables

• Drops all temporary objects

• Aborts open transactions

• Defects from a distributed transaction when enlisted

• Decrements the reference count for users in current database which releases shared database locks

• Frees acquired locks

• Releases any acquired handles

• Resets all SET options to the default values

• Resets the @@rowcount value

• Resets the @@identity value

• Resets any session level trace options using dbcc traceon()

• Resets CONTEXT_INFO to NULL in SQL Server 2005 and newer _{[ not part of the original article ]}

sp_reset_connection will NOT reset:

• Security context, which is why connection pooling matches connections based on the exact connection string

• Application roles entered using sp_setapprole, since application roles could not be reverted at all prior to SQL Server 2005. Starting in SQL Server 2005, app roles can be reverted, but only with additional information that is not part of the session. Before closing the connection, application roles need to be manually reverted via sp_unsetapprole using a "cookie" value that is captured when sp_setapprole is executed.

Note: I am including the list here as I do not want it to be lost in the ever transient web.

just take the string and use the JavaScriptSerializer to deserialize it into a native object. For example, having this json:

string json = "[{Name:'John Simith',Age:35},{Name:'Pablo Perez',Age:34}]"; 

You'd need to create a C# class called, for example, Person defined as so:

public class Person
{
 public int Age {get;set;}
 public string Name {get;set;}
}

You can now deserialize the JSON string into an array of Person by doing:

JavaScriptSerializer js = new JavaScriptSerializer();
Person [] persons =  js.Deserialize<Person[]>(json);

Here's a link to JavaScriptSerializer documentation.

Note: my code above was not tested but that's the idea Tested it. Unless you are doing something "exotic", you should be fine using the JavascriptSerializer.

Show HTML code, as-is, using the (obsolete) <xmp> tag:

_x000D_

_x000D_

<xmp>
<div>
  <input placeholder='write something' value='test'>
</div>
</xmp>

_x000D_

_x000D_

_x000D_

It is very sad this tag has been deprecated, but it does still works on browsers, it it is a bad-ass tag. no need to escape anything inside it. What a joy!

Show HTML code, as-is, using the <textarea> tag:

<textarea readonly rows="4" style="background:none; border:none; resize:none; outline:none; width:100%;">
<div>
  <input placeholder='write something' value='test'>
</div>
</textarea>

md5.h also have MD5_* functions very useful for big file

#include <openssl/md5.h>
#include <fstream>
.......

std::ifstream file(filename, std::ifstream::binary);
MD5_CTX md5Context;
MD5_Init(&md5Context);
char buf[1024 * 16];
while (file.good()) {
    file.read(buf, sizeof(buf));
    MD5_Update(&md5Context, buf, file.gcount());
}
unsigned char result[MD5_DIGEST_LENGTH];
MD5_Final(result, &md5Context);

Very simple, isn`t it? Convertion to string also very simple:

#include <sstream>
#include <iomanip>
.......

std::stringstream md5string;
md5string << std::hex << std::uppercase << std::setfill('0');
for (const auto &byte: result)
    md5string << std::setw(2) << (int)byte;

return md5string.str();

When you use varargs, it can result in the creation of an Object[] to hold the arguments.

Due to escape analysis, the JIT can optimise away this array creation. (One of the few times I have found it does so) Its not guaranteed to be optimised away, but I wouldn't worry about it unless you see its an issue in your memory profiler.

AFAIK @SafeVarargs suppresses a warning by the compiler and doesn't change how the JIT behaves.

Sounds easier to do with the standard classes:

std::complex<double> vecA(0,1);
std::complex<double> i(0,1); // 90 degrees
std::complex<double> r45(sqrt(2.0),sqrt(2.0));
vecA *= i;
vecA *= r45;

Vector rotation is a subset of complex multiplication. To rotate over an angle alpha, you multiply by std::complex<double> { cos(alpha), sin(alpha) }

Running any shell command inside $(...) will help to store the output in a variable. So using that we can convert the files to array with IFS.

IFS=' ' read -r -a array <<< $(ls /path/to/dir)

SUM(Data_free) may or may not be valid. It depends on the history of innodb_file_per_table. More discussion is found here.

Ted Hopp answered this quite nicely. I have been using res/raw for my opengl texture and shader files. I was thinking about moving them to an assets directory to provide a hierarchical organization.

This thread convinced me not to. First, because I like the use of a unique resource id. Second because it's very simple to use InputStream/openRawResource or BitmapFactory to read in the file. Third because it's very useful to be able to use in a portable library.

You cannot use primitive types in HashMap. int, or double don't work. You have to use its enclosing type. for an example

Map<String,Integer> m = new HashMap<String,Integer>();

Now both are objects, so this will work.

It's not clear to me what you want, but I'll mention that the Date class also has a compareTo method, which can be used to determine with one call if two Date objects are equal or (if they aren't equal) which occurs sooner. This allows you to do something like:

switch (today.compareTo(questionDate)) {
    case -1:  System.out.println("today is sooner than questionDate");  break;
    case 0:   System.out.println("today and questionDate are equal");  break;
    case 1:   System.out.println("today is later than questionDate");  break;
    default:  System.out.println("Invalid results from date comparison"); break;
}

It should be noted that the API docs don't guarantee the results to be -1, 0, and 1, so you may want to use if-elses rather than a switch in any production code. Also, if the second date is null, you'll get a NullPointerException, so wrapping your code in a try-catch may be useful.

This link has some useful suggestions: http://forums.iis.net/t/1085990.aspx

It depends on where you have the config settings stored. By default IIS7 will have all of it's configuration settings stored in a file called "ApplicationHost.Config". If you have delegation configured then you will see site/app related config settings getting written to web.config file for the site/app. With IIS7 on vista there is an automatica backup file for master configuration is created. This file is called "application.config.backup" and it resides inside "C:\Windows\System32\inetsrv\config" You could rename this file to applicationHost.config and replace it with the applicationHost.config inside the config folder. IIS7 on server release will have better configuration back up story, but for now I recommend using APPCMD to backup/restore your configuration on regualr basis. Example: APPCMD ADD BACK "MYBACKUP" Another option (really the last option) is to uninstall/reinstall IIS along with WPAS (Windows Process activation service).

You can not remove an item from an IEnumerable; it can only be enumerated, as described here: http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.aspx

You have to use an ICollection if you want to add and remove items. Maybe you can try and casting your IEnumerable; this will off course only work if the underlying object implements ICollection`.

See here for more on ICollection: http://msdn.microsoft.com/en-us/library/92t2ye13.aspx

You can, of course, just create a new list from your IEnumerable, as pointed out by lante, but this might be "sub optimal", depending on your actual use case, of course.

ICollection is probably the way to go.

It can be done in a single command. You need to set the IDENTITY property for "auto number":

ALTER TABLE MyTable ADD mytableID int NOT NULL IDENTITY (1,1) PRIMARY KEY

More precisely, to set a named table level constraint:

ALTER TABLE MyTable
   ADD MytableID int NOT NULL IDENTITY (1,1),
   CONSTRAINT PK_MyTable PRIMARY KEY CLUSTERED (MyTableID)

See ALTER TABLE and IDENTITY on MSDN

sudo bash -c "nohup /opt/viptel/viptel_bin/log.sh $* &> /dev/null"  &

Redirecting the output of sudo causes sudo to reask for the password, thus an awkward mechanism is needed to do this variant.

I tried type(of:...) in Playground with Swift 3. This is my result. This is the code format version.

print(String(describing: type(of: UIButton.self)))
print(String(describing: type(of: UIButton())))
UIButton.Type
UIButton

Possible solutions -
1.Make sure that you don't have any other element with name/id as submit.
2.Try to call the function as onClick = "return submitAction();"
3.document.getElementById("form-name").submit();

The meaning of the completely undocumented error 800A03EC (shame on Microsoft!) is something like "OPERATION NOT SUPPORTED".

It may happen

• when you open a document that has a content created by a newer Excel version, which your current Excel version does not understand.
• when you save a document to the same path where you have loaded it from (file is already open and locked)

But mostly you will see this error due to severe bugs in Excel.

• For example Microsoft.Office.Interop.Excel.Picture has a property "Enabled". When you call it you should receive a bool value. But instead you get an error 800A03EC. This is a bug.
• And there is a very fat bug in Exel 2013 and 2016: When you automate an Excel process and set Application.Visible=true and Application.WindowState = XlWindowState.xlMinimized then you will get hundreds of 800A03EC errors from different functions (like Range.Merge(), CheckBox.Text, Shape.TopLeftCell, Shape.Locked and many more). This bug does not exist in Excel 2007 and 2010.

In addition to the setCustomSelectionActionModeCallback, and disabled long-click solutions, it's necessary to prevent the PASTE/REPLACE menus from appearing when the text selection handle is clicked, as per the image below:

The solution lies in preventing PASTE/REPLACE menu from appearing in the show() method of the (non-documented) android.widget.Editor class. Before the menu appears, a check is done to if (!canPaste && !canSuggest) return;. The two methods that are used as the basis to set these variables are both in the EditText class:

• isSuggestionsEnabled() is public, and may thus be overridden.
• canPaste() is not, and thus must be hidden by introducing a function of the same name in the derived class.

A more complete answer is available here.

Remove warnings.filterwarnings and add:

numpy.seterr(all='raise')

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

One way to share variables across multiple controllers is to create a service and inject it in any controller where you want to use it.

Simple service example:

angular.module('myApp', [])
    .service('sharedProperties', function () {
        var property = 'First';

        return {
            getProperty: function () {
                return property;
            },
            setProperty: function(value) {
                property = value;
            }
        };
    });

Using the service in a controller:

function Ctrl2($scope, sharedProperties) {
    $scope.prop2 = "Second";
    $scope.both = sharedProperties.getProperty() + $scope.prop2;
}

This is described very nicely in this blog (Lesson 2 and on in particular).

I've found that if you want to bind to these properties across multiple controllers it works better if you bind to an object's property instead of a primitive type (boolean, string, number) to retain the bound reference.

Example: var property = { Property1: 'First' }; instead of var property = 'First';.

UPDATE: To (hopefully) make things more clear here is a fiddle that shows an example of:

• Binding to static copies of the shared value (in myController1)
  • Binding to a primitive (string)
  • Binding to an object's property (saved to a scope variable)
• Binding to shared values that update the UI as the values are updated (in myController2)
  • Binding to a function that returns a primitive (string)
  • Binding to the object's property
  • Two way binding to an object's property

you need a file named __init__.py (two underscores on each side) in every folder in the hierarchy, so one in src/ and one in model/. This is what python looks for to know that it should access a particular folder. The files are meant to contain initialization instructions but even if you create them empty this will solve it.

It depends why the something is on the same line in the first place.

clear in the case of floats, display: block in the case of inline content naturally flowing, nothing will defeat position: absolute as the previous element will be taken out of the normal flow by it.

htmlspecialchars () does the minimum amount of encoding to ensure that your string is not parsed as HTML. This leaves your string more human-readable than it would be if you used htmlentities () to encode absolutely everything that has an encoding.

Two way to add Scroll in page

1. Using SingleChildScrollView :

     SingleChildScrollView(
          child: Column(
            children: [
              Container(....),
              SizedBox(...),
              Container(...),
              Text(....)
            ],
          ),
      ),

2. Using ListView : ListView is default provide Scroll no need to add extra widget for scrolling

     ListView(
          children: [
            Container(..),
            SizedBox(..),
            Container(...),
            Text(..)
          ],
      ),

With Winforms you can use Form.BackColor to do this.
From within the Form's code:

BackColor = Color.LightPink;

If you mean a WPF Window you can use the Background property.
From within the Window's code:

Background = Brushes.LightPink;

One thing I found out is that your folder holding your php/html files cannot be named the same name as the folder in your HTDOCS carrying your project.

If you are looking inside dockerfile while creating image, add this line:

RUN apk add --update yourPackageName

There are plenty of good answers given here for loading controllers within controllers, but for me, this contradicts the mvc pattern.

The sentence that worries me is;

(filled with data processed by the product controller)

The models are there for processing and returning data. If you put this logic into your product model then you can call it from any controller you like without having to try to pervert the framework.

Once of the most helpful quotes I read was that the controller was like the 'traffic cop', there to route requests and responses between models and views.

please use this

var uri = "ws://localhost:5000/ws";
var socket = new WebSocket(uri);
socket.onclose = function (e){
    console.log(connection closed);
};
window.addEventListener("unload", function () {
    if(socket.readyState == WebSocket.OPEN)
        socket.close();
});

Close browser doesn't trigger websocket close event. You must call socket.close() manually.

Ruby's Hash#compact, Hash#compact! and Hash#delete_if! do not work on nested nil, empty? and/or blank? values. Note that the latter two methods are destructive, and that all nil, "", false, [] and {} values are counted as blank?.

Hash#compact and Hash#compact! are only available in Rails, or Ruby version 2.4.0 and above.

Here's a non-destructive solution that removes all empty arrays, hashes, strings and nil values, while keeping all false values:

(blank? can be replaced with nil? or empty? as needed.)

def remove_blank_values(hash)
  hash.each_with_object({}) do |(k, v), new_hash|
    unless v.blank? && v != false
      v.is_a?(Hash) ? new_hash[k] = remove_blank_values(v) : new_hash[k] = v
    end
  end
end

A destructive version:

def remove_blank_values!(hash)
  hash.each do |k, v|
    if v.blank? && v != false
      hash.delete(k)
    elsif v.is_a?(Hash)
      hash[k] = remove_blank_values!(v)
    end
  end
end

Or, if you want to add both versions as instance methods on the Hash class:

class Hash
  def remove_blank_values
    self.each_with_object({}) do |(k, v), new_hash|
      unless v.blank? && v != false
        v.is_a?(Hash) ? new_hash[k] = v.remove_blank_values : new_hash[k] = v
      end
    end
  end

  def remove_blank_values!
    self.each_pair do |k, v|
      if v.blank? && v != false
        self.delete(k)
      elsif v.is_a?(Hash)
        v.remove_blank_values!
      end
    end
  end
end

Other options:

• Replace v.blank? && v != false with v.nil? || v == "" to strictly remove empty strings and nil values
• Replace v.blank? && v != false with v.nil? to strictly remove nil values
• Etc.

EDITED 2017/03/15 to keep false values and present other options

Use this code:

@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "YourId" })
}

On mobile devices sending everything to the GPU will cause a memory overload and crash the application. I encountered this on an iPad app in Cordova. Best to only send the required items to the GPU, the divs that you're specifically moving around.

Better yet, use the 3d transitions transforms to do the animations like translateX(50px) as opposed to left:50px;

Add sudo to your command line, like:

$ sudo firebase init

If you absolutely must use HTML to give your text color, you have to use the (deprecated) <font>-tag:

<h2><font color="#006699">Process Report</font></h2>

But otherwise, I strongly recommend you to do as rekire said: use CSS.

Here's a simplest example from ASP.NET Community, this gave me a clear understanding on the concept....

what difference does this make?

For an example of this, here is a way to put focus on a text box on a page when the page is loaded into the browser—with Visual Basic using the RegisterStartupScript method:

Page.ClientScript.RegisterStartupScript(Me.GetType(), "Testing", _ 
"document.forms[0]['TextBox1'].focus();", True)

This works well because the textbox on the page is generated and placed on the page by the time the browser gets down to the bottom of the page and gets to this little bit of JavaScript.

But, if instead it was written like this (using the RegisterClientScriptBlock method):

Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "Testing", _
"document.forms[0]['TextBox1'].focus();", True)

Focus will not get to the textbox control and a JavaScript error will be generated on the page

The reason for this is that the browser will encounter the JavaScript before the text box is on the page. Therefore, the JavaScript will not be able to find a TextBox1.

You could also make the ajax call more generic, reusable, so you can call it from different CRUD(create, read, update, delete) tasks for example and treat the success cases from those calls.

makePostCall = function (url, data) { // here the data and url are not hardcoded anymore
   var json_data = JSON.stringify(data);

    return $.ajax({
        type: "POST",
        url: url,
        data: json_data,
        dataType: "json",
        contentType: "application/json;charset=utf-8"
    });
}

// and here a call example
makePostCall("index.php?action=READUSERS", {'city' : 'Tokio'})
    .success(function(data){
               // treat the READUSERS data returned
   })
    .fail(function(sender, message, details){
           alert("Sorry, something went wrong!");
  });

We also can use

import { Home } from './layouts/Home'; 

using export keyword before class keyword.

export class Home extends React.Component{
    render(){
        ........
    }
}

For default

 import Home from './layouts/Home'; 

Default export class

 export default class Home extends React.Component{
    render(){
        ........
    }
 }

Both case don't need to write

export default Home;

after class.

It is not necessary to use System.Drawing to find the image format in a URI. System.Drawing is not available for .NET Core unless you download the System.Drawing.Common NuGet package and therefore I don't see any good cross-platform answers to this question.

Also, my example does not use System.Net.WebClient since Microsoft explicitly discourage the use of System.Net.WebClient.

We don't recommend that you use the WebClient class for new development. Instead, use the System.Net.Http.HttpClient class.

Download an image from a URL and write it to a file (cross platform)*

*Without old System.Net.WebClient and System.Drawing.

This method will asynchronously download an image (or any file as long as the URI has a file extension) using the System.Net.Http.HttpClient and then write it to a file, using the same file extension as the image had in the URI.

Getting the file extension

First part of getting the file extension is removing all the unnecessary parts from the URI.
We use Uri.GetLeftPart() with UriPartial.Path to get everything from the Scheme up to the Path.
In other words, https://www.example.com/image.png?query&with.dots becomes https://www.example.com/image.png.

After that, we use Path.GetExtension() to get only the extension (in my previous example, .png).

var uriWithoutQuery = uri.GetLeftPart(UriPartial.Path);
var fileExtension = Path.GetExtension(uriWithoutQuery);

Downloading the image

From here it should be straight forward. Download the image with HttpClient.GetByteArrayAsync, create the path, ensure the directory exists and then write the bytes to the path with File.WriteAllBytesAsync() (or File.WriteAllBytes if you are on .NET Framework)

private async Task DownloadImageAsync(string directoryPath, string fileName, Uri uri)
{
    using var httpClient = new HttpClient();

    // Get the file extension
    var uriWithoutQuery = uri.GetLeftPart(UriPartial.Path);
    var fileExtension = Path.GetExtension(uriWithoutQuery);

    // Create file path and ensure directory exists
    var path = Path.Combine(directoryPath, $"{fileName}{fileExtension}");
    Directory.CreateDirectory(directoryPath);

    // Download the image and write to the file
    var imageBytes = await _httpClient.GetByteArrayAsync(uri);
    await File.WriteAllBytesAsync(path, imageBytes);
}

Note that you need the following using directives.

using System;
using System.IO;
using System.Threading.Tasks;
using System.Net.Http;

Example usage

var folder = "images";
var fileName = "test";
var url = "https://cdn.discordapp.com/attachments/458291463663386646/592779619212460054/Screenshot_20190624-201411.jpg?query&with.dots";

await DownloadImageAsync(folder, fileName, new Uri(url));

Notes

• It's bad practice to create a new HttpClient for every method call. It is supposed to be reused throughout the application. I wrote a short example of an ImageDownloader(50 lines) with more documentation that correctly reuses the HttpClient and properly disposes of it that you can find here.

For GlassFish Jersey JAX-RS implementation I have resolved this issue by common method is describing all common parameters. At least three of parameters have to be equal: name(="name"), path(="/") and domain(=null) :

public static NewCookie createDomainCookie(String value, int maxAgeInMinutes) {
    ZonedDateTime time = ZonedDateTime.now().plusMinutes(maxAgeInMinutes);
    Date expiry = time.toInstant().toEpochMilli();
    NewCookie newCookie = new NewCookie("name", value, "/", null, Cookie.DEFAULT_VERSION,null, maxAgeInMinutes*60, expiry, false, false);
    return newCookie;
}

And use it the common way to set cookie:

NewCookie domainNewCookie = RsCookieHelper.createDomainCookie(token, 60);
Response res = Response.status(Response.Status.OK).cookie(domainNewCookie).build();

and to delete the cookie:

NewCookie domainNewCookie = RsCookieHelper.createDomainCookie("", 0);
Response res = Response.status(Response.Status.OK).cookie(domainNewCookie).build();

Change this:

<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">

To this:

<link href="http://maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet" type="text/css">

I believe you need the http: otherwise it doesn't know what protocol to use (and uses the wrong one, file: for instance, as a result).

I had this issue with a solution containing multiple projects.

It came from duplicating a .csproj and adding the copy to the solution. A .csproj file contains a <ProjectGuid> element. I set the GUID of the copied project to a new one.

Update: Which GUID you use doesn't matter, it just needs to be different from the other project's GUID. You can create a new GUID from within Visual Studio: Tools -> Create GUID and copy the part between the curly brackets, i.e. {...}. Use that as the new value for the <ProjectGuid> element.

I also performed the following steps (not neccessarily neccessary, but they don't hurt):

1. Close the solution
2. Delete bin folder
3. Delete all obj folders
4. Open solution and build

$var:25%;
$foo:5px;
.selector {
    height:unquote("calc( #{$var} - #{$foo} )");
}

This is Function which will convert most of the video formats to number of frames there are in the video. It works on Python3 with OpenCV 3+

import cv2
import time
import os

def video_to_frames(input_loc, output_loc):
    """Function to extract frames from input video file
    and save them as separate frames in an output directory.
    Args:
        input_loc: Input video file.
        output_loc: Output directory to save the frames.
    Returns:
        None
    """
    try:
        os.mkdir(output_loc)
    except OSError:
        pass
    # Log the time
    time_start = time.time()
    # Start capturing the feed
    cap = cv2.VideoCapture(input_loc)
    # Find the number of frames
    video_length = int(cap.get(cv2.CAP_PROP_FRAME_COUNT)) - 1
    print ("Number of frames: ", video_length)
    count = 0
    print ("Converting video..\n")
    # Start converting the video
    while cap.isOpened():
        # Extract the frame
        ret, frame = cap.read()
        # Write the results back to output location.
        cv2.imwrite(output_loc + "/%#05d.jpg" % (count+1), frame)
        count = count + 1
        # If there are no more frames left
        if (count > (video_length-1)):
            # Log the time again
            time_end = time.time()
            # Release the feed
            cap.release()
            # Print stats
            print ("Done extracting frames.\n%d frames extracted" % count)
            print ("It took %d seconds forconversion." % (time_end-time_start))
            break

if __name__=="__main__":

    input_loc = '/path/to/video/00009.MTS'
    output_loc = '/path/to/output/frames/'
    video_to_frames(input_loc, output_loc)

It supports .mts and normal files like .mp4 and .avi. Tried and Tested on .mts files. Works like a Charm.

My autocomplete also didn't work because Visual Studio Tools for Unity wasn't installed. So, after you install that, delete the auto generated Visual Studio files. Others said that you open file again and the problem is solved but it's not.

The trick is: instead of normally double-clicking the file, you need to open the C# file from Unity by right click and then "Open C# Project".

There's now a much simpler solution than when this question was originally asked, five years ago. A CSS Flexbox makes the two column layout originally asked for easy. This is the bare bones equivalent of the table in the original question:

<div style="display: flex">
    <div>AAA</div>
    <div>BBB</div>
</div>

One of the nice things about a Flexbox is that it lets you easily specify how child elements should shrink and grow to adjust to the container size. I will expand on the above example to make the box the full width of the page, make the left column a minimum of 75px wide, and grow the right column to capture the leftover space. I will also pull the style into its own proper block, assign some background colors so that the columns are apparent, and add legacy Flex support for some older browsers.

<style type="text/css">
.flexbox {
    display: -ms-flex;
    display: -webkit-flex;
    display: flex;
    width: 100%;
}

.left {
    background: #a0ffa0;
    min-width: 75px;
    flex-grow: 0;
}

.right {
    background: #a0a0ff;
    flex-grow: 1;
}
</style>

...

<div class="flexbox">
    <div class="left">AAA</div>
    <div class="right">BBB</div>
</div>

Flex is relatively new, and so if you're stuck having to support IE 8 and IE 9 you can't use it. However, as of this writing, http://caniuse.com/#feat=flexbox indicates at least partial support by browsers used by 94.04% of the market.

Generally if you are not sure of what value you will end up returning, you should consider using return-type as super-class of all the return values. In this case, where you need to return String or int, consider returning Object class(which is the base class of all the classes defined in java).

But be careful to have instanceof checks where you are calling this method. Or else you may end up getting ClassCastException.

public static void main(String args[]) {
        Object obj = myMethod(); // i am calling static method from main() which return Object
    if(obj instanceof String){
    // Do something
    }else(obj instance of Integer) {
    //do something else
     }

there are many causes such as

• The network link between server and client may be temporarily going down.
• running out of system resources.
• sending malformed data.

To examine the problem in detail, you can use Wireshark.

or you can just re-request or re-connect again.

If you want to see the contents of RDD then yes collect is one option, but it fetches all the data to driver so there can be a problem

<rdd.name>.take(<num of elements you want to fetch>)

Better if you want to see just a sample

Running foreach and trying to print, I dont recommend this because if you are running this on cluster then the print logs would be local to the executor and it would print for the data accessible to that executor. print statement is not changing the state hence it is not logically wrong. To get all the logs you will have to do something like

**Pseudocode**
collect
foreach print

But this may result in job failure as collecting all the data on driver may crash it. I would suggest using take command or if u want to analyze it then use sample collect on driver or write to file and then analyze it.

If i remember correctly, you need to use the "Shapes" property of your sheet.

Each Shape object has a TopLeftCell and BottomRightCell attributes that tell you the position of the image.

Here's a piece of code i used a while ago, roughly adapted to your needs. I don't remember the specifics about all those ChartObjects and whatnot, but here it is:

For Each oShape In ActiveSheet.Shapes
    strImageName = ActiveSheet.Cells(oShape.TopLeftCell.Row, 1).Value
    oShape.Select
    'Picture format initialization
    Selection.ShapeRange.PictureFormat.Contrast = 0.5: Selection.ShapeRange.PictureFormat.Brightness = 0.5: Selection.ShapeRange.PictureFormat.ColorType = msoPictureAutomatic: Selection.ShapeRange.PictureFormat.TransparentBackground = msoFalse: Selection.ShapeRange.Fill.Visible = msoFalse: Selection.ShapeRange.Line.Visible = msoFalse: Selection.ShapeRange.Rotation = 0#: Selection.ShapeRange.PictureFormat.CropLeft = 0#: Selection.ShapeRange.PictureFormat.CropRight = 0#: Selection.ShapeRange.PictureFormat.CropTop = 0#: Selection.ShapeRange.PictureFormat.CropBottom = 0#: Selection.ShapeRange.ScaleHeight 1#, msoTrue, msoScaleFromTopLeft: Selection.ShapeRange.ScaleWidth 1#, msoTrue, msoScaleFromTopLeft
    '/Picture format initialization
    Application.Selection.CopyPicture
    Set oDia = ActiveSheet.ChartObjects.Add(0, 0, oShape.Width, oShape.Height)
    Set oChartArea = oDia.Chart
    oDia.Activate
    With oChartArea
        .ChartArea.Select
        .Paste
        .Export ("H:\Webshop_Zpider\Strukturbildene\" & strImageName & ".jpg")
    End With
    oDia.Delete 'oChartArea.Delete
Next

Try:

import java.text.DateFormatSymbols;
monthString = new DateFormatSymbols().getMonths()[month-1];

Alternatively, you could use SimpleDateFormat:

import java.text.SimpleDateFormat;
System.out.println(new SimpleDateFormat("MMMM").format(date));

(You'll have to put a date with your month in a Date object to use the second option).

I know this is old, but maybe this will help someone else.

Do not log "new" values. Your existing table, GUESTS, has the new values. You'll have double entry of data, plus your DB size will grow way too fast that way.

I cleaned this up and minimized it for this example, but here is the tables you'd need for logging off changes:

CREATE TABLE GUESTS (
      GuestID INT IDENTITY(1,1) PRIMARY KEY, 
      GuestName VARCHAR(50), 
      ModifiedBy INT, 
      ModifiedOn DATETIME
)

CREATE TABLE GUESTS_LOG (
      GuestLogID INT IDENTITY(1,1) PRIMARY KEY, 
      GuestID INT, 
      GuestName VARCHAR(50), 
      ModifiedBy INT, 
      ModifiedOn DATETIME
)

When a value changes in the GUESTS table (ex: Guest name), simply log off that entire row of data, as-is, to your Log/Audit table using the Trigger. Your GUESTS table has current data, the Log/Audit table has the old data.

Then use a select statement to get data from both tables:

SELECT 0 AS 'GuestLogID', GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS] WHERE GuestID = 1
UNION
SELECT GuestLogID, GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS_LOG] WHERE GuestID = 1
ORDER BY ModifiedOn ASC

Your data will come out with what the table looked like, from Oldest to Newest, with the first row being what was created & the last row being the current data. You can see exactly what changed, who changed it, and when they changed it.

Optionally, I used to have a function that looped through the RecordSet (in Classic ASP), and only displayed what values had changed on the web page. It made for a GREAT audit trail so that users could see what had changed over time.

When you use a CASE expression (not statement) you have to be aware of data type precedence. In this case you can't just set a DATETIME to an empty string. Try it:

SELECT CONVERT(DATETIME, '');

One workaround is to present your date as a string:

CASE WHEN CONVERT(DATE, CreatedDate) = '1900-01-01' -- to account for accidental time
  THEN ''
  ELSE CONVERT(CHAR(10), CreatedDate, 120)
    + ' ' + CONVERT(CHAR(8), CreatedDate, 108)
END 

Or you could fiddle with the presentation stuff where it belongs, at the presentation tier.

Here is an example that works exactly as you seem to want:

DECLARE @d TABLE(CreatedDate DATETIME);

INSERT @d SELECT '19000101' UNION ALL SELECT '20130321';

SELECT d = CASE WHEN CreatedDate = '19000101'
  THEN ''
  ELSE CONVERT(CHAR(10), CreatedDate, 120)
    + ' ' + CONVERT(CHAR(8), CreatedDate, 108)
END FROM @d;

Results:

d
-------------------
                    <-- empty string
2013-03-21 00:00:00

Best way to do it without having a limited buffer size is by using asprintf()

char* concat(const char* str1, const char* str2)
{
    char* result;
    asprintf(&result, "%s%s", str1, str2);
    return result;
}

revoke all distribution certificate for developer.apple.com and the validate your app in Xcode there will be the option to create a new distribution certificate after you can export key for further use.

This work for me.

If you're adding a pile of anchors to the DOM, look into event delegation instead.

Here's a simple example:

$('#somecontainer').click(function(e) {   
  var $target = $(e.target);   
  if ($target.hasClass("myclass")) {
    // do something
  }
});

<form name="myForm" method="post">
  <p>Activity</p> 
  skiing:  <input type="checkbox" name="activity" value="skiing"  checked="yes" /><br /> 
  skating: <input type="checkbox" name="activity" value="skating" /><br /> 
  running: <input type="checkbox" name="activity" value="running" /><br /> 
  hiking:  <input type="checkbox" name="activity" value="hiking"  checked="yes" />
</form>

You declared them, but not initialized.

int a; // declaration, unknown value
a = 0; // initialization
int a = 0; // declaration with initialization

IF NOT USING THE SHORT HAND VERSION: Make sure the animation-fill-mode: forwards is AFTER the animation declaration or it will not work...

animation-fill-mode: forwards;
animation-name: appear;
animation-duration: 1s;
animation-delay: 1s;

vs

animation-name: appear;
animation-duration: 1s;
animation-fill-mode: forwards;
animation-delay: 1s;

Here is a trick if you want to calculate maximum(field, 0):

SELECT (ABS(field) + field)/2 FROM Table

returns 0 if field is negative, else, return field.

Another way: you can use RedisWorks library.

pip install redisworks

>>> from redisworks import Root
>>> root = Root()
>>> root.something = {1:"a", "b": {2: 2}}  # saves it as Hash type in Redis
...
>>> print(root.something)  # loads it from Redis
{'b': {2: 2}, 1: 'a'}
>>> root.something['b'][2]
2

It converts python types to Redis types and vice-versa.

>>> root.sides = [10, [1, 2]]  # saves it as list in Redis.
>>> print(root.sides)  # loads it from Redis
[10, [1, 2]]
>>> type(root.sides[1])
<class 'list'>

Disclaimer: I wrote the library. Here is the code: https://github.com/seperman/redisworks

It was interesting to find a better solution:

var escapeHTML = function(unsafe) {
  return unsafe.replace(/[&<"']/g, function(m) {
    switch (m) {
      case '&':
        return '&amp;';
      case '<':
        return '&lt;';
      case '"':
        return '&quot;';
      default:
        return '&#039;';
    }
  });
};

I do not parse > because it does not break XML/HTML code in the result.

Here are the benchmarks: http://jsperf.com/regexpairs Also, I created a universal escape function: http://jsperf.com/regexpairs2

Named instances?

URL: jdbc:sqlserver://[serverName][\instanceName][:portNumber][;property=value]

Note: backward slash

First install node-static server via npm install node-static -g -g is to install it global on your system, then navigate to the directory where your files are located, start the server with static it listens on port 8080, naviaget to the browser and type localhost:8080/yourhtmlfilename.

I know its quite late to answer this, but I guess it will help anyone ahead.

Well using CSS3 FlexBox. It can be acheived. Make you header as display:flex and divide its entire width into 3 parts. In the first part I have placed the logo, the searchbar in second part and buttons container in last part. apply justify-content: between to the header container and flex-grow:1 to the searchbar. That's it. The sample code is below.

#header {_x000D_
  background-color: #323C3E;_x000D_
  justify-content: space-between;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
#searchBar, img{_x000D_
  align-self: center;_x000D_
}_x000D_
_x000D_
#searchBar{_x000D_
  flex-grow:1;_x000D_
  background-color: orange;_x000D_
  padding: 10px;_x000D_
}_x000D_
_x000D_
#searchBar input {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
.button {_x000D_
  padding: 22px;_x000D_
}_x000D_
_x000D_
.buttonsHolder{_x000D_
  display:flex;_x000D_
}

<div id="header" class="d-flex justify-content-between">_x000D_
    <img src="img/logo.png" />_x000D_
    <div id="searchBar">_x000D_
      <input type="text" />_x000D_
    </div>_x000D_
    <div class="buttonsHolder">_x000D_
      <div class="button orange inline" id="myAccount">_x000D_
        My Account_x000D_
      </div>_x000D_
      <div class="button red inline" id="basket">_x000D_
        Basket (2)_x000D_
      </div>_x000D_
    </div>_x000D_
</div>

You need to give the array a size:

public static void main(String args[])
{
    int array[] = new int[4];
    int number = 5, i = 0,j = 0;
    while (i<4){
        array[i]=number;
        i=i+1;
    }
    while (j<4){
        System.out.println(array[j]);
        j++;
    }
}

Use quit() in this context. break expects to be inside a loop, and return expects to be inside a function.

my form:

<form method="post" action="radio.php">
   select your gender: 
    <input type="radio" name="radioGender" value="female">
    <input type="radio" name="radioGender" value="male">
    <input type="submit" name="btnSubmit" value="submit">
</form>

my php:

   <?php
      if (isset($_POST["btnSubmit"])) {
        if (isset($_POST["radioGender"])) {
        $answer = $_POST['radioGender'];
           if ($answer == "female") {
               echo "female";
           } else {
               echo "male";
           }    
        }else{
            echo "please select your gender";
             }
      }
  ?>

You should push the new viewcontroller by using current navigation controller, not present.

self.navigationController.pushViewController(nextViewController, animated: true)

The best way to force a specific JVM for MAVEN is to create a system wide file loaded by the mvn script.

This file is /etc/mavenrc and it must declare a JAVA_HOME environment variable pointing to your specific JVM.

Example:

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-amd64

If the file exists, it's loaded.

Here is an extract of the mvn script in order to understand :

  if [ -f /etc/mavenrc ] ; then
    . /etc/mavenrc
  fi

  if [ -f "$HOME/.mavenrc" ] ; then
    . "$HOME/.mavenrc"
  fi

Alternately, the same content can be written in ~/.mavenrc

SHOW CREATE TABLE bar;

you will get a create statement for that table, edit the table name, or anything else you like, and then execute it.

This will allow you to copy the indexes and also manually tweak the table creation.

You can also run the query within a program.

You are disabling only on document.ready and this happens only once when DOM is ready but you need to disable in keyup event too when textbox gets empty. Also change $(this).val.length to $(this).val().length

$(document).ready(function(){
    $('.sendButton').attr('disabled',true);
    $('#message').keyup(function(){
        if($(this).val().length !=0)
            $('.sendButton').attr('disabled', false);            
        else
            $('.sendButton').attr('disabled',true);
    })
});

Or you can use conditional operator instead of if statement. also use prop instead of attr as attribute is not recommended by jQuery 1.6 and above for disabled, checked etc.

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method, jQuery docs

$(document).ready(function(){
    $('.sendButton').prop('disabled',true);
    $('#message').keyup(function(){
        $('.sendButton').prop('disabled', this.value == "" ? true : false);     
    })
});  

onResume() is one of the methods called throughout the activity lifecycle. onResume() is the counterpart to onPause() which is called anytime an activity is hidden from view, e.g. if you start a new activity that hides it. onResume() is called when the activity that was hidden comes back to view on the screen.

You're question asks abou what method is used to restart an activity. onCreate() is called when the activity is first created. In practice, most activities persist in the background through a series of onPause() and onResume() calls. An activity is only really "restarted" by onRestart() if it is first fully stopped by calling onStop() and then brought back to life. Thus if you are not actually stopping activities with onStop() it is most likley you will be using onResume().

Read the android doc in the above link to get a better understanding of the relationship between the different lifestyle methods. Regardless of which lifecycle method you end up using the general format is the same. You must override the standard method and include your code, i.e. what you want the activity to do at that point, in the commented section.

@Override
public void onResume(){
 //will be executed onResume
}

Your query has 8 or possibly even 9 variables, ie. Name, Description etc. But the values, these things ---> '', '%s', '%s', '%s', '%s', '%s', '%s', '%s')", only total 7, the number of variables have to be the same as the values.

I had the same problem but I figured it out. Hopefully it will also work for you.

You have to write: sqrt = x**(1/2.0), otherwise an integer division is performed and the expression 1/2 returns 0.

This behavior is "normal" in Python 2.x, whereas in Python 3.x 1/2 evaluates to 0.5. If you want your Python 2.x code to behave like 3.x w.r.t. division write from __future__ import division - then 1/2 will evaluate to 0.5 and for backwards compatibility, 1//2 will evaluate to 0.

And for the record, the preferred way to calculate a square root is this:

import math
math.sqrt(x)

Heres a simple solution thats working for me... similar to some of the others posted, but it doesn't not include the need for calling sizeToFit

Note this is written in Swift 5

let lbl = UILabel()
lbl.numberOfLines = 0
lbl.font = UIFont.systemFont(ofSize: 12) // make sure you set this correctly 
lbl.text = "My text that may or may not wrap lines..."

let width = 100.0 // the width of the view you are constraint to, keep in mind any applied margins here

let height = lbl.systemLayoutSizeFitting(CGSize(width: width, height: UIView.layoutFittingCompressedSize.height), withHorizontalFittingPriority: .required, verticalFittingPriority: .fittingSizeLevel).height

This handles line wrapping and such. Not the most elegant code, but it gets the job done.

can't really see your table, but flag cannot be both 'Volunteer' and 'Uploaded'. If you have multiple values in a column, you can use

WHERE flag LIKE "%Volunteer%" AND flag LIKE "%UPLOADED%"

not really applicable seeing the formatted table.

Here is some help for 2Tier and 3Tier difference, please refer below.

ANSWER:
1. 2Tier is Client server architecture and 3Tier is Client, Server and Database architecture.
2. 3Tier has a Middle stage to communicate client to server, Where as in 2Tier client directly get communication to server.
3. 3Tier is like a MVC, But having difference in topologies
4. 3Tier is linear means in that request flow is Client>>>Middle Layer(SErver application) >>>Databse server and Response is reverse.
While in 2Tier it a Triangular View >>Controller>>Model
5. 3Tier is like Website while web browser is Client application(middle layer), and ASP/PHP language code is server application.

Use the basename method of the path module:

path.basename('/foo/bar/baz/asdf/quux.html')
// returns
'quux.html'

Here is the documentation the above example is taken from.

As an update to Scott Munro's answer:

• In C# 6.0 and VB.NET 14.0 (VS 2015), either Environment.ExitCode or Environment.Exit(exitCode) is required to return an non-zero code from a console application. Changing the return type of Main has no effect.
• In F# 4.0 (VS 2015), the return value of the main entry point is respected.

There's a KVC Object Operator that offers a more elegant solution uniquearray = [yourarray valueForKeyPath:@"@distinctUnionOfObjects.self"]; Here's an NSArray category.

Simplification of @Daira Hopwood method good for picking one single commit. Need no temporary branches.

In the case of the author:

• Z is wanted commit (fd9f578)
• Y is commit before it
• X current working branch

then do:

git checkout Z   # move HEAD to wanted commit
git reset Y      # have Z as changes in working tree
git stash        # save Z in stash
git checkout X   # return to working branch
git stash pop    # apply Z to current branch
git commit -a    # do commit

If your library is set up as an Android library (i.e. it uses the apply plugin: 'com.android.library' statement in its build.gradle file), it will output an .aar when it's built. It will show up in the build/outputs/aar/ directory in your module's directory.

You can choose the "Android Library" type in File > New Module to create a new Android Library.

type MyProps = {
  workoutType: string | null;
};

When dealing with day-of-week calculations, it's important to take account of the current DATEFIRST settings. This query will always correctly exclude weekend days, using @@DATEFIRST to account for any possible setting for the first day of the week.

SELECT *
FROM your_table
WHERE ((DATEPART(dw, date_created) + @@DATEFIRST) % 7) NOT IN (0, 1)

if you are looking for something speedy, here's a method I've been using that's worked for years:

from array import array

with open( path, 'rb' ) as file:
    data = array( 'B', file.read() ) # buffer the file

# evaluate it's data
for byte in data:
    v = byte # int value
    c = chr(byte)

if you want to iterate chars instead of ints, you can simply use data = file.read(), which should be a bytes() object in py3.

You can hide the title of a dialog using:

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

Previous version of this answer, which is overcomplicated:

You need to use an AlertDialog. There's a good explanation on the Android Developer's site about custom dialogs.

In very short summary, you do this with code like copied below from the official website. That takes a custom layot file, inflates it, gives it some basic text and icon, then creates it. You'd show it then with alertDialog.show().

AlertDialog.Builder builder;
AlertDialog alertDialog;

Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater)
        mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_dialog,
        (ViewGroup) findViewById(R.id.layout_root));

TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView) layout.findViewById(R.id.image);
image.setImageResource(R.drawable.android);

builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();

In response to comment:

I assume that TextView with the id nr is in the View you are inflating with View view = inflater..... If so, then you need to change just one bit: instead of dialog.findView... make it view.findView.... Then once you've done that, remember to use dialog.show(), or even builder.show() without bothering to do builder.create().

Working from what you've given I'll assume you want to check that someone has NOT entered any letters other than the ones you've listed. For that to work you want to search for any characters other than those listed:

[^A-Za-z0-9_.]

And use that in a match in your code, something like:

if ( /[^A-Za-z0-9_.]/.match( your_input_string ) ) {
   alert( "you have entered invalid data" );
}

Hows that?

You can try this:

select
  count(distinct tag) as tag_count,
  count(distinct (case when entryId > 0 then tag end)) as positive_tag_count
from
  your_table_name;

The first count(distinct...) is easy. The second one, looks somewhat complex, is actually the same as the first one, except that you use case...when clause. In the case...when clause, you filter only positive values. Zeros or negative values would be evaluated as null and won't be included in count.

One thing to note here is that this can be done by reading the table once. When it seems that you have to read the same table twice or more, it can actually be done by reading once, in most of the time. As a result, it will finish the task a lot faster with less I/O.

you can use the following to get all the lines in the file

$handle = @fopen('test.txt', "r");

if ($handle) { 
   while (!feof($handle)) { 
       $lines[] = fgets($handle, 4096); 
   } 
   fclose($handle); 
} 


print_r($lines);

and $lines[1] for your second line

Add hadoop.tmp.dir property in core-site.xml

<configuration>
  <property>
    <name>fs.defaultFS</name>
    <value>hdfs://localhost:9000</value>
  </property>
  <property>
    <name>hadoop.tmp.dir</name>
    <value>/home/yourname/hadoop/tmp/hadoop-${user.name}</value>
  </property>
</configuration>

and format hdfs (hadoop 2.7.1):

$ hdfs namenode -format

The default value in core-default.xml is /tmp/hadoop-${user.name}, which will be deleted after reboot.

Swift UI solution

Button(action: {}) {
            Text("Button")
        }.foregroundColor(Color(red: 1.0, green: 0.0, blue: 0.0))

Swift 3, Swift 4, Swift 5

to improve comments. This should work:

button.setTitleColor(.red, for: .normal)

Say you have a DIV you want centred horizontally:

 <div id="foo">Lorem ipsum</div>

In the CSS you'd style it with this:

#foo
{
  margin:0 auto; 
  width:30%;
}

Which states that you have a top and bottom margin of zero pixels, and on either left or right, automatically work out how much is needed to be even.

Doesn't really matter what you put in for the width, as long as it's there and isn't 100%. Otherwise you wouldn't be setting the centre on anything.

But if you float it, left or right, then the bets are off since that pulls it out of the normal flow of elements on the page and the auto margin setting won't work.

A not well known feature of numpy is to use r_. This is a simple way to build up arrays quickly:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.r_[a[None,:],b[None,:]]
print(c)
#[[1 2 3]
# [4 5 6]]

The purpose of a[None,:] is to add an axis to array a.

There's actually a good reason:
The non-static access does not always work, for reasons of ambiguity.

Suppose we have two classes, A and B, the latter being a subclass of A, with static fields with the same name:

public class A {
    public static String VALUE = "Aaa";
}

public class B extends A {
    public static String VALUE = "Bbb";
}

Direct access to the static variable:

A.VALUE (="Aaa")
B.VALUE (="Bbb")

Indirect access using an instance (gives a compiler warning that VALUE should be statically accessed):

new B().VALUE (="Bbb")

So far, so good, the compiler can guess which static variable to use, the one on the superclass is somehow farther away, seems somehow logical.

Now to the point where it gets tricky: Interfaces can also have static variables.

public interface C {
    public static String VALUE = "Ccc";
}

public interface D {
    public static String VALUE = "Ddd";
}

Let's remove the static variable from B, and observe following situations:

• B implements C, D
• B extends A implements C
• B extends A implements C, D
• B extends A implements C where A implements D
• B extends A implements C where C extends D
• ...

The statement new B().VALUE is now ambiguous, as the compiler cannot decide which static variable was meant, and will report it as an error:

error: reference to VALUE is ambiguous
both variable VALUE in C and variable VALUE in D match

And that's exactly the reason why static variables should be accessed in a static way.

You don't need jQuery for this. You can use JavaScript's .childNodes.length.

Just make sure to subtract 1 if you don't want to include the default text node (which is empty by default). Thus, you'd use the following:

var count = elem.childNodes.length - 1;

you are probably using android.support.v4.app.Fragment. For this instead of onAttach method, just use getActivity() to get the FragmentActivity with which the fragment is associated with. Else you could use onAttach(Context context) method.

I realize this question is old, but it recently popped up in a search I just ran, so I thought I'd post an alternative to the above answer.

If you are looking to generate create scripts programmatically in .Net, I would highly recommend looking into Server Management Objects (SMO) or Distributed Management Objects (DMO) -- depending on which version of SQL Server you are using (the former is 2005+, the latter 2000). Using these libraries, scripting a table is as easy as:

Server server      = new Server(".");
Database northwind = server.Databases["Northwind"];
Table categories   = northwind.Tables["Categories"];

StringCollection script = categories.Script();
string[] scriptArray    = new string[script.Count];

script.CopyTo(scriptArray, 0);

Here is a blog post with more information.

As Leigh Caldwell has stated, the query optimizer can produce different query plans based on what functionally looks like the same SQL statement. For further reading on this, have a look at the following two blog postings:-

If you are getting 'Enter Encryption Key' dialog box error:

I am using Swift 2.1 with Realm 0.96.2 and was getting this error when trying to open the database file:

'default' could not be opened. It may be encrypted, or it isn't in a compatible file format. If you know the file is encrypted, you can manually enter its encryption key to open it.

Found that using the pre-release version of the Realm Browser 0.96 fixed the issue:

https://github.com/realm/realm-browser-osx/releases/tag/0.96-prerelease

If you are using Eclipse, this should be easy:

1.Press Alt+Shift+S

2.Choose "Generate toString()..."

Enjoy! You can have any template of toString()s.

This also works with getter/setters.

If you want to match the error code exactly (eg equals 0), use this:

@echo off
my_nify_exe.exe
if %ERRORLEVEL% EQU 0 (
   echo Success
) else (
   echo Failure Reason Given is %errorlevel%
   exit /b %errorlevel%
)

if errorlevel 0 matches errorlevel >= 0. See if /?.

This is not the most robust solution - but if you're just looking to create a partitioned rank on a field with only a few different values, it may not be unwieldily to use some case when logic with as many variables as you require.

Something like this has worked for me in the past:

SELECT t.*, 
   CASE WHEN <partition_field> = @rownum1 := @rownum1 + 1 
     WHEN <partition_field> = @rownum2 := @rownum2 + 1 
     ...
     END AS rank
FROM YOUR_TABLE t, 
   (SELECT @rownum1 := 0) r1, (SELECT @rownum2 := 0) r2
ORDER BY <rank_order_by_field>
;

Hope that makes sense / helps!

I applied CSS styling to an anchored HREF attribute fully emulating the push button behaviors I needed (hover, active, background-color, etc., etc.). HTML markup is much simpler a-n-d eliminates the get/post complexity associated with using a form-based approach.

When you think your git is messed up, you can use this command to do everything up-to-date.

git rm -r --cached .
git add .
git commit -am 'git cache cleared'
git push

Also to revert back last commit use this :

git reset HEAD^ --hard

DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());         
connection = DriverManager.getConnection("jdbc:oracle:thin:@machinename:portnum:schemaname","userid","password");

In the link you provided, thats not a loop in sql...

thats a loop in programming language

they are first getting list of all distinct districts, and then for each district executing query again.

sendStickyBroadcast() performs a sendBroadcast(Intent) known as sticky, i.e. the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of registerReceiver(BroadcastReceiver, IntentFilter). In all other ways, this behaves the same as sendBroadcast(Intent). One example of a sticky broadcast sent via the operating system is ACTION_BATTERY_CHANGED. When you call registerReceiver() for that action -- even with a null BroadcastReceiver -- you get the Intent that was last broadcast for that action. Hence, you can use this to find the state of the battery without necessarily registering for all future state changes in the battery.

while and for statements can both be used for looping in programming. It will depend on the programmer as to whether the while loop or for loop is used. Some are comfortable using while loop and some are with for loop.

Use any loop you like. However, the do...while loop can be somewhat tricky in C programming.

This way you can set the fontSize and can handle it in just one class.

1. Created an extension of UIButton and added following code:

- (void)awakeFromNib{

    [super awakeFromNib];

    [self setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [self.titleLabel setFont:[UIFont fontWithName:@"font" 
                                     size:self.titleLabel.font.pointSize]];
    [self setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];
}

2.1 Create UIButton inside Code

Now if you create a UIButton inside your code, #import the extension of yourUIButton` and create the Button.

2.2 Create Button in Interface Builder

If you create the UIButton inside the Interface Builder, select the UIButton, go to the Identity Inspector and add the created extension as class for the UIButton.

String.Join() is implemented quite fast, and as you already have a collection of the strings in question, is probably the best choice. Above all, it shouts "I'm joining a list of strings!" Always nice.

It should be 236 bytes. There is no restriction on the size of the alert text as far as I know, but only the total payload size. So considering if the payload is minimal and only contains the alert information, it should look like:

{"aps":{"alert":""}}

That takes up 20 characters (20 bytes), leaving 236 bytes to put inside the alert string. With ASCII that will be 236 characters, and could be lesser with UTF8 and UTF16.

ProcessStartInfo startInfo = new ProcessStartInfo(string.Concat(cPath, "\\", "HHTCtrlp.exe"));
startInfo.Arguments =cParams;
startInfo.UseShellExecute = false; 
System.Diagnostics.Process.Start(startInfo);

I have a naive solution but useful. Here is the code:

<Grid Name="TVGrid" Background="#7F000000">  <ScrollBar Background="Black" Orientation="Vertical" Height="35" HorizontalAlignment="Left" Margin="215,254,0,0" Minimum="0" Maximum="10" LargeChange="10" Value="{Binding ElementName=channeltext2, Path=Text}" x:Name="scroll" VerticalAlignment="Top" Width="12" RenderTransformOrigin="0.5,0.5" ValueChanged="scroll_ValueChanged" >  
        <ScrollBar.RenderTransform>  
            <TransformGroup>  
                <ScaleTransform/>  
                <SkewTransform/>  
                <RotateTransform Angle="-180"/>  
                <TranslateTransform/>  
            </TransformGroup>  
        </ScrollBar.RenderTransform>  
    </ScrollBar>  
    <TextBox Name="channeltext" HorizontalContentAlignment="Center" FontSize="20"  Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />  
    <TextBox Name="channeltext2" Visibility="Hidden" HorizontalContentAlignment="Center" FontSize="20"  Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />  </Grid>  

Try this one:

.modal-open {
    overflow: hidden;
    position:fixed;
    width: 100%;
    height: 100%;
}

it worked for me. (supports IE8)

[your Array name] = Empty

Then the array will be without content and can be filled again.

Above solutions did not work for bitbucket. I figured this does the trick:

RUN ssh-keyscan bitbucket.org >> /root/.ssh/known_hosts \
    && eval `ssh-agent` \
    && ssh-add ~/.ssh/[key] \
    && git clone [email protected]:[team]/[repo].git

0 will get printed.

As in C++ true refers to 1 and false refers to 0.

In case, you want to print false instead of 0,then you have to sets the boolalpha format flag for the str stream.

When the boolalpha format flag is set, bool values are inserted/extracted by their textual representation: either true or false, instead of integral values.

#include <iostream>
int main()
{
  std::cout << std::boolalpha << false << std::endl;
}

output:

false

IDEONE

If you create a background Service that does all the heavy lifting (tcp requests/response, unmarshalling), the View and Activity can be destroyed and re-created without leaking window or losing data. This allows the Android recommended behavior, which is to destroy an Activity on each configuration change (eg. for each orientation change).

It is a bit more complex, but it is the best way for invoking server request, data pre/post-processing, etc.

You may even use your Service to queue each request to a server, so it makes it easy and efficient to handle those things.

The dev guide has a full chapter on Services.

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

I don't have enough points to comment on an answer, but I wanted to say that mikec's answer worked for me except that I had to change it to return !isScrollable like so:

mScroller.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
      return !isScrollable;
    }
});

Also useful:

let multiLineString = """
                  Line One
                  Line Two
                  Line Three
                  """

• Makes the code read more understandable
• Allows copy pasting

You are missimg @ModelAttribute annotation for UserProfessionalForm professionalForm parameter in forgotPassword method.

@RequestMapping(value = "proffessional", method = RequestMethod.POST)
public @ResponseBody
String forgotPassword(@ModelAttribute UserProfessionalForm professionalForm,
        BindingResult result, Model model) {

    UserProfileVO userProfileVO = new UserProfileVO();
    userProfileVO.setUser(sessionData.getUser());
    userService.saveUserProfile(userProfileVO);
    model.addAttribute("professional", professionalForm);
    return "Your Professional Details Updated";
}

I tried with an alternate method:

Hit F12 key Then, at right hand side in the drop down menu, select internet explorer version 9.

That's it and it worked for me.

If someone was looking for a way to remove all instances of repeated values, see "How can I efficiently extract repeated elements in a Ruby array?".

a = [1, 2, 2, 3]
counts = Hash.new(0)
a.each { |v| counts[v] += 1 }
p counts.select { |v, count| count == 1 }.keys # [1, 3]

Using print function without parentheses works with older versions of Python but is no longer supported on Python3, so you have to put the arguments inside parentheses. However, there are workarounds, as mentioned in the answers to this question. Since the support for Python2 has ended in Jan 1st 2020, the answer has been modified to be compatible with Python3.

You could do any of these (and there may be other ways):

(1)  print("First number is {} and second number is {}".format(first, second))
(1b) print("First number is {first} and number is {second}".format(first=first, second=second)) 

or

(2) print('First number is', first, 'second number is', second) 

(Note: A space will be automatically added afterwards when separated from a comma)

or

(3) print('First number %d and second number is %d' % (first, second))

or

(4) print('First number is ' + str(first) + ' second number is' + str(second))
  

Using format() (1/1b) is preferred where available.

This question has been answered already, but thought I'd add to the mix what I found out when I got these messages.

I have a repo called playground that contains a number of sandbox apps. I added two new apps from a tutorial to the playground directory by cloning the tutorial's repo. The result was that the new apps' git stuff pointed to the tutorial's repo and not to my repo. The solution was to delete the .git directory from each of those apps' directories, mv the apps' directories outside the playground directory, and then mv them back and run git add .. After that it worked.

Here ngOnChanges will trigger always when your input property changes:

ngOnChanges(changes: SimpleChanges): void {
 console.log(changes.categoryId.currentValue)
}

You can use async/await for this. I would explain more, but there's nothing really to it. It's just a regular for loop but I added the await keyword before the construction of your Promise

What I like about this is your Promise can resolve a normal value instead of having a side effect like your code (or other answers here) include. This gives you powers like in The Legend of Zelda: A Link to the Past where you can affect things in both the Light World and the Dark World – ie, you can easily work with data before/after the Promised data is available without having to resort to deeply nested functions, other unwieldy control structures, or stupid IIFEs.

// where DarkWorld is in the scary, unknown future
// where LightWorld is the world we saved from Ganondorf
LightWorld ... await DarkWorld

So here's what that will look like ...

const someProcedure = async n =>_x000D_
  {_x000D_
    for (let i = 0; i < n; i++) {_x000D_
      const t = Math.random() * 1000_x000D_
      const x = await new Promise(r => setTimeout(r, t, i))_x000D_
      console.log (i, x)_x000D_
    }_x000D_
    return 'done'_x000D_
  }_x000D_
_x000D_
someProcedure(10).then(x => console.log(x)) // => Promise_x000D_
// 0 0_x000D_
// 1 1_x000D_
// 2 2_x000D_
// 3 3_x000D_
// 4 4_x000D_
// 5 5_x000D_
// 6 6_x000D_
// 7 7_x000D_
// 8 8_x000D_
// 9 9_x000D_
// done

See how we don't have to deal with that bothersome .then call within our procedure? And async keyword will automatically ensure that a Promise is returned, so we can chain a .then call on the returned value. This sets us up for great success: run the sequence of n Promises, then do something important – like display a success/error message.

CoreUtils referred to in other posts does NOT show the real implementation of most of the functionality which I think you seek. In most cases it provides front-ends for the actual functions that retrieve the data, which can be found here:

It is build upon Gnulib with the actual source code in the lib-subdirectory

For Angular 2+ you can run this in the console:

document.querySelector('[ng-version]').getAttribute('ng-version')

For AngularJS 1.x:

angular.version.full

Very simple.... Try these steps:

Step 1: Add the SystemConfiguration framework into your project.

Step 2: Import the following code into your header file.

#import <SystemConfiguration/SystemConfiguration.h>

Step 3: Use the following method

• Type 1:

  - (BOOL) currentNetworkStatus {
      [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
      BOOL connected;
      BOOL isConnected;
      const char *host = "www.apple.com";
      SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL, host);
      SCNetworkReachabilityFlags flags;
      connected = SCNetworkReachabilityGetFlags(reachability, &flags);
      isConnected = NO;
      isConnected = connected && (flags & kSCNetworkFlagsReachable) && !(flags & kSCNetworkFlagsConnectionRequired);
      CFRelease(reachability);
      return isConnected;
  }
  

• Type 2:

  Import header : #import "Reachability.h"

  - (BOOL)currentNetworkStatus
  {
      Reachability *reachability = [Reachability reachabilityForInternetConnection];
      NetworkStatus networkStatus = [reachability currentReachabilityStatus];
      return networkStatus != NotReachable;
  }
  

Step 4: How to use:

- (void)CheckInternet
{
    BOOL network = [self currentNetworkStatus];
    if (network)
    {
        NSLog(@"Network Available");
    }
    else
    {
        NSLog(@"No Network Available");
    }
}

You can create table variable instead of tamp table in procedure A and execute procedure B and insert into temp table by below query.

DECLARE @T TABLE
(
TABLE DEFINITION
)
.
.
.
INSERT INTO @T
EXEC B @MYDATE

and you continue operation.

Much longer solution, but accounts for the following scenarios:

1. Is the image smaller than the bounding box?
2. Is the Image and the Bounding Box square?
3. Is the Image square and the bounding box isn't
4. Is the image wider and taller than the bounding box
5. Is the image wider than the bounding box

6. Is the image taller than the bounding box

   private Image ResizePhoto(FileInfo sourceImage, int desiredWidth, int desiredHeight)
   {
       //throw error if bouning box is to small
       if (desiredWidth < 4 || desiredHeight < 4)
           throw new InvalidOperationException("Bounding Box of Resize Photo must be larger than 4X4 pixels.");            
       var original = Bitmap.FromFile(sourceImage.FullName);
   
       //store image widths in variable for easier use
       var oW = (decimal)original.Width;
       var oH = (decimal)original.Height;
       var dW = (decimal)desiredWidth;
       var dH = (decimal)desiredHeight;
   
       //check if image already fits
       if (oW < dW && oH < dH)
           return original; //image fits in bounding box, keep size (center with css) If we made it bigger it would stretch the image resulting in loss of quality.
   
       //check for double squares
       if (oW == oH && dW == dH)
       {
           //image and bounding box are square, no need to calculate aspects, just downsize it with the bounding box
           Bitmap square = new Bitmap(original, (int)dW, (int)dH);
           original.Dispose();
           return square;

       //check original image is square
       if (oW == oH)
       {
           //image is square, bounding box isn't.  Get smallest side of bounding box and resize to a square of that center the image vertically and horizontally with Css there will be space on one side.
           int smallSide = (int)Math.Min(dW, dH);
           Bitmap square = new Bitmap(original, smallSide, smallSide);
           original.Dispose();
           return square;
       }
   
       //not dealing with squares, figure out resizing within aspect ratios            
       if (oW > dW && oH > dH) //image is wider and taller than bounding box
       {
           var r = Math.Min(dW, dH) / Math.Min(oW, oH); //two dimensions so figure out which bounding box dimension is the smallest and which original image dimension is the smallest, already know original image is larger than bounding box
           var nH = oH * r; //will downscale the original image by an aspect ratio to fit in the bounding box at the maximum size within aspect ratio.
           var nW = oW * r;
           var resized = new Bitmap(original, (int)nW, (int)nH);
           original.Dispose();
           return resized;
       }
       else
       {
           if (oW > dW) //image is wider than bounding box
           {
               var r = dW / oW; //one dimension (width) so calculate the aspect ratio between the bounding box width and original image width
               var nW = oW * r; //downscale image by r to fit in the bounding box...
               var nH = oH * r;
               var resized = new Bitmap(original, (int)nW, (int)nH);
               original.Dispose();
               return resized;
           }
           else
           {
               //original image is taller than bounding box
               var r = dH / oH;
               var nH = oH * r;
               var nW = oW * r;
               var resized = new Bitmap(original, (int)nW, (int)nH);
               original.Dispose();
               return resized;
           }
       }
   }
   

I also had an issue displaying charectors like "? U".I added the following to my web.xml.

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <page-encoding>UTF-8</page-encoding>
    </jsp-property-group>
</jsp-config>

This solved the issue in the pages except header. Tried many ways to solve this and nothing worked in my case. The issue with header was header jsp page is included from another jsp. So gave the encoding to the import and that solved my problem.

<c:import url="/Header1.jsp" charEncoding="UTF-8"/>

Thanks

It seems that each project may have a separate collection of python libraries in a project specific computing environment. To get this working with numpy I went to the terminal at the bottom of the pycharm window and ran pip install numpy and once the process finished running the install and indexing my python project was able to import numpy from the line of code import numpy as np. It seems you may need to do this for each project you setup in numpy.

Use jquery attr method. It works in all browsers.

var hiddenInput = document.createElement("input");
$(hiddenInput).attr({
    'id':'uniqueIdentifier',
    'type': 'hidden',
    'value': ID,
    'class': 'ListItem'
});

Or you could use folowing code:

var e = $('<input id = "uniqueIdentifier" type="hidden" value="' + ID + '" class="ListItem" />');

For modern reference, in Symfony 2.4+, you cannot name the arguments for the Constructor Injection method anymore. According to the documentation You would pass in:

services:
    test.common.userservice:
        class:  Test\CommonBundle\Services\UserService
        arguments: [ "@doctrine.orm.entity_manager" ]

And then they would be available in the order they were listed via the arguments (if there are more than 1).

public function __construct(EntityManager $entityManager) {
    $this->em = $entityManager;
}

SOLUTION After all this time, I managed to resolve the problem.

I am a beginner with Angular and I did the basic mistake of not including the app name in the angular root element. So, changing the code from

<html data-ng-app> 

to

<html data-ng-app="myApp"> 

worked for me. @PSL, has covered this already in his answer above.

This is due to path not set where keytool.exe present.

Open command prompt in windows machine, traverse where you would like to run keytool cmd and set path where keytool.exe present

Step 1 : Open cmd promt and run "cd C:\Program Files\Java\jdk1.8.0_131\jre\lib\security"

Step 2 : Run below cmd to set path using "set PATH=C:\Program Files\Java\jdk1.8.0_131\bin"

Step 3 : Run keytool cmd, now it will be able to recognize.

I'm not sure if there is but if there was such a property it wouldn't be considered reliable. A WebException can be fired for reasons other than HTTP error codes including simple networking errors. Those have no such matching http error code.

Can you give us a bit more info on what you're trying to accomplish with that code. There may be a better way to get the information you need.

There is a style that I've created based on dark style from VS 2015 to use on my VS 2010. You can download this style from Dark Style from VS 2015.

Example doubling the image size

There are two ways to resize an image. The new size can be specified:

1. Manually;

   height, width = src.shape[:2]

   dst = cv2.resize(src, (2*width, 2*height), interpolation = cv2.INTER_CUBIC)

2. By a scaling factor.

   dst = cv2.resize(src, None, fx = 2, fy = 2, interpolation = cv2.INTER_CUBIC), where fx is the scaling factor along the horizontal axis and fy along the vertical axis.

To shrink an image, it will generally look best with INTER_AREA interpolation, whereas to enlarge an image, it will generally look best with INTER_CUBIC (slow) or INTER_LINEAR (faster but still looks OK).

Example shrink image to fit a max height/width (keeping aspect ratio)

import cv2

img = cv2.imread('YOUR_PATH_TO_IMG')

height, width = img.shape[:2]
max_height = 300
max_width = 300

# only shrink if img is bigger than required
if max_height < height or max_width < width:
    # get scaling factor
    scaling_factor = max_height / float(height)
    if max_width/float(width) < scaling_factor:
        scaling_factor = max_width / float(width)
    # resize image
    img = cv2.resize(img, None, fx=scaling_factor, fy=scaling_factor, interpolation=cv2.INTER_AREA)

cv2.imshow("Shrinked image", img)
key = cv2.waitKey()

Using your code with cv2

import cv2 as cv

im = cv.imread(path)

height, width = im.shape[:2]

thumbnail = cv.resize(im, (round(width / 10), round(height / 10)), interpolation=cv.INTER_AREA)

cv.imshow('exampleshq', thumbnail)
cv.waitKey(0)
cv.destroyAllWindows()

The other answers and comments are correct in that to examine the contents of a stream, one must add a terminal operation, thereby "consuming" the stream. However, one can do this and turn the result back into a stream, without buffering up the entire contents of the stream. Here are a couple examples:

static <T> Stream<T> throwIfEmpty(Stream<T> stream) {
    Iterator<T> iterator = stream.iterator();
    if (iterator.hasNext()) {
        return StreamSupport.stream(Spliterators.spliteratorUnknownSize(iterator, 0), false);
    } else {
        throw new NoSuchElementException("empty stream");
    }
}

static <T> Stream<T> defaultIfEmpty(Stream<T> stream, Supplier<T> supplier) {
    Iterator<T> iterator = stream.iterator();
    if (iterator.hasNext()) {
        return StreamSupport.stream(Spliterators.spliteratorUnknownSize(iterator, 0), false);
    } else {
        return Stream.of(supplier.get());
    }
}

Basically turn the stream into an Iterator in order to call hasNext() on it, and if true, turn the Iterator back into a Stream. This is inefficient in that all subsequent operations on the stream will go through the Iterator's hasNext() and next() methods, which also implies that the stream is effectively processed sequentially (even if it's later turned parallel). However, this does allow you to test the stream without buffering up all of its elements.

There is probably a way to do this using a Spliterator instead of an Iterator. This potentially allows the returned stream to have the same characteristics as the input stream, including running in parallel.

Apple annoyingly rejects many HTML5 web standards on their iOS devices, for a variety of business reasons. Ultimately, you can't pre-load or auto-play sound files before a touch event, it only plays one sound at a time, and it doesn't support Ogg/Vorbis. However, I did find one nifty workaround to let you have a little more control over the audio.

<audio id="soundHandle" style="display:none;"></audio>

<script type="text/javascript">

var soundHandle = document.getElementById('soundHandle');

$(document).ready(function() {
    addEventListener('touchstart', function (e) {
        soundHandle.src = 'audio.mp3';
        soundHandle.loop = true;
        soundHandle.play();
        soundHandle.pause();
    });
});

</script>

Basically, you start playing the audio file on the very first touch event, then you pause it immediately. Now, you can use the soundHandle.play() and soundHandle.pause() commands throughout your Javascript and control the audio without touch events. If you can time it perfectly, just have the pause come in right after the sound is over. Then next time you play it again, it will loop back to the beginning. This won't resolve all the mess Apple has made here, but it's one solution.

mysqli_real_escape_string function requires the connection to your database.

$username = mysqli_real_escape_string($your_connection, $_POST['username']);

P.S.: Do not mix mysql_ functions* and mysqli_ functions*. Please use mysqli_* functions or PDO because mysql_* functions are deprecated and will be removed in the future.

You need to use this line of code to resolve your problem:

__block Person *aPerson = nil;

For more details, please refer to this tutorial: Blocks and Variables

The simple solution given by Jonathan works with a modification to cheat Pandoc. Instead of direct Latex commands such as

\begin{center}
Text
\end{center}

you can define your own commands in the YAML header:

header-includes:
- \newcommand{\bcenter}{\begin{center}}
- \newcommand{\ecenter}{\end{center}}

And then you use:

\bcenter
Text and more
\ecenter

This works for me for centering a whole document with many code chunks and markdown commands in between.
