I think you want to print the name of the person or both the name and email :

const renObjData = this.props.data.map(function(data, idx) {
    return <p key={idx}>{data.name}</p>;
});

or :

const renObjData = this.props.data.map(function(data, idx) {
   return ([
       <p key={idx}>{data.name}</p>,
       <p key={idx}>{data.email}</p>,
   ]);
});

Safe Methods : Get Resource/No modification in resource
Idempotent : No change in resource status if requested many times
Unsafe Methods : Create or Update Resource/Modification in resource
Non-Idempotent : Change in resource status if requested many times

According to your requirement :

1) For safe and idempotent operation (Fetch Resource) use --------- GET METHOD
2) For unsafe and non-idempotent operation (Insert Resource) use--------- POST METHOD
3) For unsafe and idempotent operation (Update Resource) use--------- PUT METHOD
3) For unsafe and idempotent operation (Delete Resource) use--------- DELETE METHOD

This is not a bug- you can only transition on ordinal/calculable properties (an easy way of thinking of this is any property with a numeric start and end number value..though there are a few exceptions).

This is because transitions work by calculating keyframes between two values, and producing an animation by extrapolating intermediate amounts.

visibility in this case is a binary setting (visible/hidden), so once the transition duration elapses, the property simply switches state, you see this as a delay- but it can actually be seen as the final keyframe of the transition animation, with the intermediary keyframes not having been calculated (what constitutes the values between hidden/visible? Opacity? Dimension? As it is not explicit, they are not calculated).

opacity is a value setting (0-1), so keyframes can be calculated across the duration provided.

A list of transitionable (animatable) properties can be found here

Clyde's solution works, but it is a broadcast, which I am pretty sure will be less efficient than calling a method directly. I could be mistaken, but I think the broadcasts are meant more for inter-application communication.

I'm assuming you already know how to bind a service with an Activity. I do something sort of like the code below to handle this kind of problem:

class MyService extends Service {
    MyFragment mMyFragment = null;
    MyFragment mMyOtherFragment = null;

    private void networkLoop() {
        ...

        //received new data for list.
        if(myFragment != null)
            myFragment.updateList();
        }

        ...

        //received new data for textView
        if(myFragment !=null)
            myFragment.updateText();

        ...

        //received new data for textView
        if(myOtherFragment !=null)
            myOtherFragment.updateSomething();

        ...
    }
}


class MyFragment extends Fragment {

    public void onResume() {
        super.onResume()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyFragment=this;
    }

    public void onPause() {
        super.onPause()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyFragment=null;
    }

    public void updateList() {
        runOnUiThread(new Runnable() {
            public void run() {
                //Update the list.
            }
        });
    }

    public void updateText() {
       //as above
    }
}

class MyOtherFragment extends Fragment {
             public void onResume() {
        super.onResume()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyOtherFragment=this;
    }

    public void onPause() {
        super.onPause()
        //Assuming your activity bound to your service
        getActivity().mMyService.mMyOtherFragment=null;
    }

    public void updateSomething() {//etc... }
}

I left out bits for thread safety, which is essential. Make sure to use locks or something like that when checking and using or changing the fragment references on the service.

This is a sample implementation of taking input in java, I added some fault tolerance on just the salary field to show how it's done. If you notice, you also have to close the input stream .. Enjoy :-)

    System.out.println("** Taking in User input **");

    Scanner input = new Scanner(System.in);

To lose the focus when other view is touched , both views should be set as view.focusableInTouchMode(true).

But it seems that use focuses in touch mode are not recommended. Please take a look here: http://android-developers.blogspot.com/2008/12/touch-mode.html

I have struggled a long time to modify the extension attributes in our domain. Then I wrote a powershell script and created an editor with a GUI to set and remove extAttributes from an account.

If you like, you can take a look at it at http://toolbocks.de/viewtopic.php?f=3&t=4

I'm sorry, that the description in the text is in German. The GUI itself is in English.

I use this script on a regular basis in our domain and it never deleted anything or did any other harm. I provide no guarantee, that this script works as expected in your domain. But as I provide the source, you can (and should) have a look at it, before you run it.

If you don't have repeated values, you could use set difference.

x = set(range(10))
y = x - set([2, 3, 7])
# y = set([0, 1, 4, 5, 6, 8, 9])

and then convert back to list, if needed.

It's a simplifications but very easy... You need to add the the focusable flag to the checkbox, as written before. You need also to add the clickable flag, as shown here:

android:focusable="false"
android:clickable="false"

Than you control the checkbox state from within the ListView (ListFragment in my case) onListItemClick event.

This the sample onListItemClick method:

public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
//Get related checkbox and change flag status..
CheckBox cb = (CheckBox)v.findViewById(R.id.rowDone);
cb.setChecked(!cb.isChecked());
Toast.makeText(getActivity(), "Click item", Toast.LENGTH_SHORT).show();
}

Perhaps there are those still looking for this but finding Google Dynamic icons deprecated and other map-icon libraries just a little bit too ugly.

To add a simple marker with any number inside using a URL. In Google Drive using the Google My Maps, it creates numbered icons when using a map layer that is set to 'Sequence of Numbers' and then adding markers/points on the map.

Looking at the source code, Google has their own way of doing it through a URL:

https://mt.google.com/vt/icon/name=icons/onion/SHARED-mymaps-container-bg_4x.png,icons/onion/SHARED-mymaps-container_4x.png,icons/onion/1738-blank-sequence_4x.png&highlight=ff000000,0288D1,ff000000&scale=2.0&color=ffffffff&psize=15&text=56&font=fonts/Roboto-Medium.ttf

Above URL

I haven't played extensively with it but by changing the hex color codes in the 'highlight' parameter(color parameter does not change the color as you may think), the 'text' value can be set to any string and you can make a nice round icon with any number/value inside. I'm sure the other parameters may be of use too.

One caveat with this approach, who knows when Google will remove this URL from the world!

Or you can do it like this!

    def skip_elements(elements):
        # Initialize variables
        new_list = []
        i = 0

        # Iterate through the list
        for words in elements:

            # Does this element belong in the resulting list?
            if i <= len(elements):
                # Add this element to the resulting list
                new_list.append(elements[i])
            # Increment i
                i += 2

        return new_list

    print(skip_elements(["a", "b", "c", "d", "e", "f", "g"])) # Should be ['a', 'c', 'e', 'g']
    print(skip_elements(['Orange', 'Pineapple', 'Strawberry', 'Kiwi', 'Peach'])) # Should be ['Orange', 'Strawberry', 'Peach']
    print(skip_elements([])) # Should be []

At the moment there are three realy powerfull cmd.exe alternatives:

• cmder
  
• PowerCmd
• ComEmu
• Terminal for Windows 10
  

cmder is an enhancement off ConEmu and Clink

All have features like Copy & Paste, Window Resize per Mouse, Splitscreen, Tabs and a lot of other usefull features.

I'm interpreting your question to be about getting row numbers.

• You can try as.numeric(rownames(df)) if you haven't set the rownames. Otherwise use a sequence of 1:nrow(df).
• The which() function converts a TRUE/FALSE row index into row numbers.

On ubuntu you can add this PPA Repository and use it to install python 3.7: https://launchpad.net/~jonathonf/+archive/ubuntu/python-3.7

Or a different PPA that provides several Python versions is Deadsnakes: https://launchpad.net/~deadsnakes/+archive/ubuntu/ppa

See also here: https://askubuntu.com/questions/865554/how-do-i-install-python-3-6-using-apt-get (I know it says 3.6 in the url, but the deadsnakes ppa also contains 3.7 so you can use it for 3.7 just the same)

If you want "official" you'd have to install it from the sources from the site, get the code (which you already downloaded) and do this:

tar -xf Python-3.7.0.tar.xz
cd Python-3.7.0
./configure
make
sudo make install        <-- sudo is required.

This might take a while

NewLine (\n) is 10 (0xA) and CarriageReturn (\r) is 13 (0xD).

Different operating systems picked different end of line representations for files. Windows uses CRLF (\r\n). Unix uses LF (\n). Older Mac OS versions use CR (\r), but OS X switched to the Unix character.

Here is a relatively useful FAQ.

You can use

adb shell ps | grep apps | awk '{print $9}'

to produce an output like:

com.google.process.gapps
com.google.android.apps.uploader
com.google.android.apps.plus
com.google.android.apps.maps
com.google.android.apps.maps:GoogleLocationService
com.google.android.apps.maps:FriendService
com.google.android.apps.maps:LocationFriendService

adb shell ps returns a list of all running processes on the android device, grep apps searches for any row with contains "apps", as you can see above they are all com.google.android.APPS. or GAPPS, awk extracts the 9th column which in this case is the package name.

To search for a particular package use

adb shell ps | grep PACKAGE.NAME.HERE | awk '{print $9}'

i.e adb shell ps | grep com.we7.player | awk '{print $9}'

If it is running the name will appear, if not there will be no result returned.

Taking @chrissr's answer and running with it, this code can be implemented into a nice category on NSUserDefaults to save and retrieve custom objects:

@interface NSUserDefaults (NSUserDefaultsExtensions)

- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key;
- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key;

@end


@implementation NSUserDefaults (NSUserDefaultsExtensions)


- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key {
    NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    [self setObject:encodedObject forKey:key];
    [self synchronize];

}

- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key {
    NSData *encodedObject = [self objectForKey:key];
    id<NSCoding> object = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];
    return object;
}

@end

Usage:

[[NSUserDefaults standardUserDefaults] saveCustomObject:myObject key:@"myKey"];

It is the CSS child selector. Example:

div > p selects all paragraphs that are direct children of div.

According to the packages list in Ubuntu Wily Xenial Bionic there is a package named openjfx. This should be a candidate for what you're looking for:

JavaFX/OpenJFX 8 - Rich client application platform for Java

You can install it via:

sudo apt-get install openjfx

It provides the following JAR files to the OpenJDK installation on Ubuntu systems:

/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/jfxswt.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/ant-javafx.jar
/usr/lib/jvm/java-8-openjdk-amd64/lib/javafx-mx.jar

If you want to have sources available, for example for debugging, you can additionally install:

sudo apt-get install openjfx-source

Just add 'change' listener on your input whose type is file. i.e

<input type="file" id="file_to_upload" name="file_to_upload" />

I have done using jQuery and obviously anyone can use valina JS (as per the requirement).

$("#file_to_upload").change(function() {

            if (this.files.length) {

            alert('file choosen');

            } else {

            alert('file NOT choosen');

            }

    });

This piece of code may help..

#include <bits/stdc++.h>
using namespace std;    

class node{
public:
    int age;
    string name;
    node(int a, string b){
        age = a;
        name = b;
    }
};

bool operator<(const node& a, const node& b) {

    node temp1=a,temp2=b;
    if(a.age != b.age)
        return a.age > b.age;
    else{
        return temp1.name.append(temp2.name) > temp2.name.append(temp1.name);
    }
}

int main(){
    priority_queue<node> pq;
    node b(23,"prashantandsoon..");
    node a(22,"prashant");
    node c(22,"prashantonly");
    pq.push(b);
    pq.push(a);
    pq.push(c);

    int size = pq.size();
    for (int i = 0; i < size; ++i)
    {
        cout<<pq.top().age<<" "<<pq.top().name<<"\n";
        pq.pop();
    }
}

Output:

22 prashantonly
22 prashant
23 prashantandsoon..

I know this is old, but I thought it might be helpful to show what these functions look like in code. This really illustrates the logic, better than text or a table IMO. In reality they are implemented in C rather than pure Python, but these are equivalent.

def any(iterable):
    for item in iterable:
        if item:
            return True
    return False

def all(iterable):
    for item in iterable:
        if not item:
            return False
    return True

In particular, you can see that the result for empty iterables is just the natural result, not a special case. You can also see the short-circuiting behaviour; it would actually be more work for there not to be short-circuiting.

When Guido van Rossum (the creator of Python) first proposed adding any() and all(), he explained them by just posting exactly the above snippets of code.

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

I had the same problem with nothing was returned from render.

It turns out that my code issue with curly braces {}. I wrote my code like this:

import React from 'react';

const Header = () => {
    <nav class="navbar"></nav>
}

export default Header;

It must be within ():

import React from 'react';

const Header = () => (
    <nav class="navbar"></nav>
);

export default Header;

You could use Universal Encoding Detector, but be aware that it will just give you best guess, not the actual encoding, because it's impossible to know encoding of a string "abc" for example. You will need to get encoding information elsewhere, eg HTTP protocol uses Content-Type header for that.

Here's the answer that I found for my question:

urlList1.FocusedItem.Index

And I am getting selected item value by:

urlList1.Items(urlList1.FocusedItem.Index).SubItems(0).Text

You can use pickle

import pickle
dict = {'one': 1, 'two': 2}
file = open('dump.txt', 'wb')
pickle.dump(dict, file)
file.close()

and to read it again

file = open('dump.txt', 'rb')
dict = pickle.load(file)

EDIT: Guess I misread your question, sorry ... but pickle might help all the same. :)

See this picture. :)

import --> const --> var --> init()

1. If a package imports other packages, the imported packages are initialized first.

2. Current package's constant initialized then.

3. Current package's variables are initialized then.

4. Finally, init() function of current package is called.

A package can have multiple init functions (either in a single file or distributed across multiple files) and they are called in the order in which they are presented to the compiler.

A package will be initialised only once even if it is imported from multiple packages.

function my_get_tags_sitemap(){
    if ( !function_exists('wp_tag_cloud') || get_option('cb2_noposttags')) return;
    $unlinkTags = get_option('cb2_unlinkTags'); 
    echo '<div class="tags"><h2>Tags</h2>';
    $ret = []; // here you need to add array which you call inside implode function
    if($unlinkTags)
    {
        $tags = get_tags();
        foreach ($tags as $tag){
            $ret[]= $tag->name;
        }
        //ERROR OCCURS HERE
        echo implode(', ', $ret);
    }
    else
    {
        wp_tag_cloud('separator=, &smallest=11&largest=11');
    }
    echo '</div>';
}

Phuong:

Sorting 40,000 random numbers:

0.022 seconds

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Random;


public class test
{
    public static void main(String[] args)
    {
        List<Integer> nums = new ArrayList<Integer>();
        Random rand = new Random();
        for( int i = 0; i < 40000; i++ )
        {
            nums.add( rand.nextInt(Integer.MAX_VALUE) );
        }

        long start = System.nanoTime();
        Collections.sort(nums);
        long end = System.nanoTime();

        System.out.println((end-start)/1e9);
    }
}   

Since you rarely need sorting, as per your problem statement, this is probably more efficient than it needs to be.

The body element takes the available width, which is usually your browser viewport. As such, it will be different dimensions cross browser due to browser chrome borders, scrollbars, vertical space being take up by menus and whatnot...

The fact that the heights also vary, also tells me you set the body/html height to 100% through css since the height is usually dependant on elements inside the body..

Unless you set the width of the body element to a fixed value through css or it's style property, it's dimensions will as a rule, always vary cross browsers/versions and perhaps even depending on plugins you installed for the browser. Constant values in such a case is more an exception to the rule...

When you invoke .clientWidth on other elements that do not take the automatic width of the browser viewport, it will always return the elements 'width' + 'padding'. So a div with width 200 and a padding of 20 will have clientWidth = 240 (20 padding left and right).

The main reason however, why one would invoke clientWidth, is exactly due to possible expected discrepancies in results. If you know you will get a constant width and the value is known, then invoking clientWidth is redundant...

You need to understand, the component hierarchy you are having and how you are passing props, definitely your case is special and not usually encountered by the devs.

Parent Component -myProp-> Child Component -myProp-> Grandchild Component

If myProp is changed in parent component it will be reflected in the child component too.

And if myProp is changed in child component it will be reflected in grandchild component too.

So if myProp is changed in parent component then it will be reflected in grandchild component. (so far so good).

Therefore down the hierarchy you don't have to do anything props will be inherently reactive.

Now talking about going up in hierarchy

If myProp is changed in grandChild component it won't be reflected in the child component. You have to use .sync modifier in child and emit event from the grandChild component.

If myProp is changed in child component it won't be reflected in the parent component. You have to use .sync modifier in parent and emit event from the child component.

If myProp is changed in grandChild component it won't be reflected in the parent component (obviously). You have to use .sync modifier child and emit event from the grandchild component, then watch the prop in child component and emit an event on change which is being listened by parent component using .sync modifier.

Let's see some code to avoid confusion

But after this you wont help notice the screaming warnings of vue saying

'Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders.'

Again as I mentioned earlier most of the devs don't encounter this issue, because it's an anti pattern. That's why you get this warning.

But in order to solve your issue (according to your design). I believe you have to do the above work around(hack to be honest). I still recommend you should rethink your design and make is less prone to bugs.

I hope it helps.

To get the logical xor of two or more variables in Python:

1. Convert inputs to booleans
2. Use the bitwise xor operator (^ or operator.xor)

For example,

bool(a) ^ bool(b)

When you convert the inputs to booleans, bitwise xor becomes logical xor.

Note that the accepted answer is wrong: != is not the same as xor in Python because of the subtlety of operator chaining.

For instance, the xor of the three values below is wrong when using !=:

True ^  False ^  False  # True, as expected of XOR
True != False != False  # False! Equivalent to `(True != False) and (False != False)`

(P.S. I tried editing the accepted answer to include this warning, but my change was rejected.)

In my scenario, I want to update the status of status based on his id

student_obj = StudentStatus.objects.get(student_id=101)
student_obj.status= 'Enrolled'
student_obj.save()

Or If you want the last id from Student_Info table you can use the following.

student_obj = StudentStatus.objects.get(student_id=StudentInfo.objects.last().id)
student_obj.status= 'Enrolled'
student_obj.save()

Here is the way to access :after and :before style properties, defined in css:

// Get the color value of .element:before
var color = window.getComputedStyle(
    document.querySelector('.element'), ':before'
).getPropertyValue('color');

// Get the content value of .element:before
var content = window.getComputedStyle(
    document.querySelector('.element'), ':before'
).getPropertyValue('content');

cfeduke notes the possibility of calling GetPEKind. It's potentially interesting to do this from PowerShell.

Here, for example, is code for a cmdlet that could be used: https://stackoverflow.com/a/16181743/64257

Alternatively, at https://stackoverflow.com/a/4719567/64257 it is noted that "there's also the Get-PEHeader cmdlet in the PowerShell Community Extensions that can be used to test for executable images."

I needed to specify min-height

#login
    display: flex
    align-items: center
    justify-content: center
    min-height: 16em

Still pretty bewildering. It seems some combination of the above suggestions worked in Eclipse 3.7.2.

First, I had to move to a network that dl-ssl.google.com hasn't blocked (this is an ongoing problem with the Google server) (Easy with a laptop, less so with my tower.)

The Eclipse folks should look at this problem. The user sees an error, something about a missing package "org.eclipse.wst.sse.core', say. There are 50 or so plugin repositories listed. which of these is the one that has this package??? None has a name containing a 'wst' or 'sse'.

This is very poor. There needs to be a way for the user to associate the error message with a repository solution.

Anyway: after some hunt-and-peck I ended up selecting (and reloading each repository, and with Contact all update sites during install to find required software checked)

• https://dl-ssl.google.com/android/eclipse/ (ADT Plugin, which I added according to the Google instructions)
• http://download.eclipse.org/releases/helios (Helios Milestone repository)
• http://download.eclipse.org/eclipse/updates/3.6 (Eclipse Project Test Site)

One of these provided the packages needed for the Android plugin . Best guess: Helios.

After processing the POST page, redirect the user to the same page.

On http://test.com/test.php

header('Location: http://test.com/test.php');

This will get rid of the box, as refreshing the page will not resubmit the data.

You can use arg(), as follow:

double dbl = 0.25874601;
QString str = QString("%1").arg(dbl);

This overcomes the problem of: "Fixed precision" at the other functions like: setNum() and number(), which will generate random numbers to complete the defined precision

Obligatory: SHA1 is broken, you can compute SHA1 collisions for 45,000 USD. You should use sha256:

var getSHA256ofJSON = function(input){
    return crypto.createHash('sha256').update(JSON.stringify(input)).digest('hex')
}

To answer your question and make a SHA1 hash:

const INSECURE_ALGORITHM = 'sha1'
var getInsecureSHA1ofJSON = function(input){
    return crypto.createHash(INSECURE_ALGORITHM).update(JSON.stringify(input)).digest('hex')
}

Then:

getSHA256ofJSON('whatever')

or

getSHA256ofJSON(['whatever'])

or

getSHA256ofJSON({'this':'too'})

Official node docs on crypto.createHash()

Strangely enough, the solution ended up being to change

volumes:
  - ./postgres-data:/var/lib/postgresql

to

volumes:
  - ./postgres-data:/var/lib/postgresql/data

The working code

var jsonData = [{person:"me", age :"30"},{person:"you",age:"25"}];_x000D_
_x000D_
for(var obj in jsonData){_x000D_
    if(jsonData.hasOwnProperty(obj)){_x000D_
    for(var prop in jsonData[obj]){_x000D_
        if(jsonData[obj].hasOwnProperty(prop)){_x000D_
           alert(prop + ':' + jsonData[obj][prop]);_x000D_
        }_x000D_
    }_x000D_
}_x000D_
}

I'd like to do this way :)

const sthError = () => Promise.reject('sth error');

const test = opts => {
  return (async () => {

    // do sth
    await sthError();
    return 'ok';

  })().catch(err => {
    console.error(err); // error will be catched there 
  });
};

test().then(ret => {
  console.log(ret);
});

It's similar to handling error with co

const test = opts => {
  return co(function*() {

    // do sth
    yield sthError();
    return 'ok';

  }).catch(err => {
    console.error(err);
  });
};

You could use regular expressions to count for you.

String subject = "First Line\n Second Line\nThird Line";  
Matcher wordM = Pattern.compile("\\b\\S+?\\b").matcher(subject); //matches a word
Matcher charM = Pattern.compile(".").matcher(subject); //matches a character
Matcher newLineM = Pattern.compile("\\r?\\n").matcher(subject); //matches a linebreak

int words=0,chars=0,newLines=1; //newLines is initially 1 because the first line has no corresponding linebreak

while(wordM.find()) words++;
while(charM.find()) chars++;
while(newLineM.find()) newLines++;

System.out.println("Words: "+words);
System.out.println("Chars: "+chars);
System.out.println("Lines: "+newLines);

UserDict from the Python standard library is designed for this purpose.

//paste required image on C disk
JButton button = new JButton(new ImageIcon("C:water.bmp");

There are two main differences from double:

• Arbitrary precision, similarly to BigInteger they can contain number of arbitrary precision and size
• Base 10 instead of Base 2, a BigDecimal is n*10^scale where n is an arbitrary large signed integer and scale can be thought of as the number of digits to move the decimal point left or right

The reason you should use BigDecimal for monetary calculations is not that it can represent any number, but that it can represent all numbers that can be represented in decimal notion and that include virtually all numbers in the monetary world (you never transfer 1/3 $ to someone).

I know this is an older post but one thing to watch out for when you cannot change the security is to make sure that your username and password are set.

I had a service with authenticationMode as UserNameOverTransport, when the username and password were not set for the service client I would get this error.

Do it like this:

SSLSocket socket = (SSLSocket) sslFactory.createSocket(host, port);
socket.setEnabledProtocols(new String[]{"SSLv3", "TLSv1"});

Simple Steps:

-Open Eclipse.

• Select Project which you want to push on github->rightclick.
• select Team->share Project->Git->Create repository->finish.(it will ask to login in Git account(popup).
• Right click again to Project->Team->commit. you are done

If anyone is looking into this, I've been trying different options and the following approach yields very good results. The following are the steps to get a working example:

1. Add .NET Wrapper for tesseract to your project. It can be added via NuGet package Install-Package Tesseract(https://github.com/charlesw/tesseract).
2. Go to the Downloads section of the official Tesseract project (https://code.google.com/p/tesseract-ocr/ EDIT: It's now located here: https://github.com/tesseract-ocr/langdata).
3. Download the preferred language data, example: tesseract-ocr-3.02.eng.tar.gz English language data for Tesseract 3.02.
4. Create tessdata directory in your project and place the language data files in it.
5. Go to Properties of the newly added files and set them to copy on build.
6. Add a reference to System.Drawing.
7. From .NET Wrapper repository, in the Samples directory copy the sample phototest.tif file into your project directory and set it to copy on build.
8. Create the following two files in your project (just to get started):

Program.cs

using System;
using Tesseract;
using System.Diagnostics;

namespace ConsoleApplication
{
    class Program
    {
        public static void Main(string[] args)
        {
            var testImagePath = "./phototest.tif";
            if (args.Length > 0)
            {
                testImagePath = args[0];
            }

            try

                using (var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
                {
                    using (var img = Pix.LoadFromFile(testImagePath))
                    {

                            using (var page = engine.Process(img))
                            {

I think gradle 2.14.1 fixes the issue. The accepted answer is correct, but there is a bug in gradle with –refresh-dependencies. 2.14.1 fixes that.

This is not the exact answer for your question, but this may help you

public class JsonParser {

    private static DefaultHttpClient httpClient = ConnectionManager.getClient();

    public static List<Club> getNearestClubs(double lat, double lon) {
        // YOUR URL GOES HERE
        String getUrl = Constants.BASE_URL + String.format("getClosestClubs?lat=%f&lon=%f", lat, lon);

        List<Club> ret = new ArrayList<Club>();

        HttpResponse response = null;
        HttpGet getMethod = new HttpGet(getUrl);
        try {
            response = httpClient.execute(getMethod);

            // CONVERT RESPONSE TO STRING
            String result = EntityUtils.toString(response.getEntity());

            // CONVERT RESPONSE STRING TO JSON ARRAY
            JSONArray ja = new JSONArray(result);

            // ITERATE THROUGH AND RETRIEVE CLUB FIELDS
            int n = ja.length();
            for (int i = 0; i < n; i++) {
                // GET INDIVIDUAL JSON OBJECT FROM JSON ARRAY
                JSONObject jo = ja.getJSONObject(i);

                // RETRIEVE EACH JSON OBJECT'S FIELDS
                long id = jo.getLong("id");
                String name = jo.getString("name");
                String address = jo.getString("address");
                String country = jo.getString("country");
                String zip = jo.getString("zip");
                double clat = jo.getDouble("lat");
                double clon = jo.getDouble("lon");
                String url = jo.getString("url");
                String number = jo.getString("number");

                // CONVERT DATA FIELDS TO CLUB OBJECT
                Club c = new Club(id, name, address, country, zip, clat, clon, url, number);
                ret.add(c);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        // RETURN LIST OF CLUBS
        return ret;
    }

}
Again, it’s relatively straight forward, but the methods I’ll make special note of are:

JSONArray ja = new JSONArray(result);
JSONObject jo = ja.getJSONObject(i);
long id = jo.getLong("id");
String name = jo.getString("name");
double clat = jo.getDouble("lat");

Use the document.createElement function and then add it as a child of your select.

var newOption = document.createElement("option");
newOption.text = 'the options text';
newOption.value = 'some value if you want it';
daySelect.appendChild(newOption);

It's short hand for the ternary operator.

FormsAuth = (formsAuth != null) ? formsAuth : new FormsAuthenticationWrapper();

Or for those who don't do ternary:

if (formsAuth != null)
{
  FormsAuth = formsAuth;
}
else
{
  FormsAuth = new FormsAuthenticationWrapper();
}

This is not lightweight but is a nice solution that gives docker feature parity with full desktop virtualization. Both Xfce4 or IceWM for Ubuntu and CentOS work, and the noVNC option makes for an easy access through a browser.

https://github.com/ConSol/docker-headless-vnc-container

It runs noVNC as well as tigerVNC's vncserver. Then it calls startx for given Window Manager. In addition, libnss_wrapper.so is used to emulate password management for the users.

In my experience, it's just a matter of iteration. Put your data and code wherever you think they go. Chances are, you'll be wrong anyway. But once you get a better idea of exactly how things are going to shape up, you're in a much better position to make these kinds of guesses.

As far as extension sources, we have a Code directory under trunk that contains a directory for python and a directory for various other languages. Personally, I'm more inclined to try putting any extension code into its own repository next time around.

With that said, I go back to my initial point: don't make too big a deal out of it. Put it somewhere that seems to work for you. If you find something that doesn't work, it can (and should) be changed.

Whenever you want to execute an SQL statement that shouldn't return a value or a record set, the ExecuteNonQuery should be used.

So if you want to run an update, delete, or insert statement, you should use the ExecuteNonQuery. ExecuteNonQuery returns the number of rows affected by the statement. This sounds very nice, but whenever you use the SQL Server 2005 IDE or Visual Studio to create a stored procedure it adds a small line that ruins everything.

That line is: SET NOCOUNT ON; This line turns on the NOCOUNT feature of SQL Server, which "Stops the message indicating the number of rows affected by a Transact-SQL statement from being returned as part of the results" and therefore it makes the stored procedure always to return -1 when called from the application (in my case a web application).

In conclusion, remove that line from your stored procedure, and you will now get a value indicating the number of rows affected by the statement.

Happy programming!

Make SymbolIndexer( const SymbolIndexer& ) private. If you're assigning to a reference, you're not copying.

I have used this a few moments ago, requires the least potentially destructive commands:

cd existing-dir
git clone --bare repo-to-clone .git
git config --unset core.bare
git remote rm origin
git remote add origin repo-to-clone
git reset

And voilá!

On your storyboard page, go to File Inspector and uncheck 'Use Size Classes'. This should shrink your view controller to regular IPhone size you were familiar with. Note that using 'size classes' will let you design your project across many devices. Once you uncheck this the Xcode will give you a warning dialogue as follows. This should be self-explainatory.

"Disabling size classes will limit this document to storing data for a single device family. The data for the size class best representing the targeted device will be retained, and all other data will be removed. In addition, segues will be converted to their non-adaptive equivalents."

Here is a simple one liner function

//ECHMA5
function GetMonth(anyDate) { 
   return 'Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec'.split(',')[anyDate.getMonth()];
 }
//
// ECMA6
var GetMonth = (anyDate) => 'Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec'.split(',')[anyDate.getMonth()];

From Android Support Library 23.2.1 update, all WRAP_CONTENT should work correctly.

In general, you can use the System.Diagnostics.StackTrace class to get a System.Diagnostics.StackFrame, and then use the GetMethod() method to get a System.Reflection.MethodBase object. However, there are some caveats to this approach:

1. It represents the runtime stack -- optimizations could inline a method, and you will not see that method in the stack trace.
2. It will not show any native frames, so if there's even a chance your method is being called by a native method, this will not work, and there is in-fact no currently available way to do it.

(NOTE: I am just expanding on the answer provided by Firas Assad.)

If you can live with 01 for January instead of 1, then try...

d = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print datetime.date.strftime(d, "%m/%d/%y")

You can check the docs for other formatting directives.

In my case I had to add both 'user agent' and 'default credentials = True'. I know this is pretty old, still wanted to share. Hope this helps. Below code is in powershell, but it should help others who are using c#.

[System.Net.HttpWebRequest] $req = [System.Net.HttpWebRequest]::Create($uri)
$req.UserAgent = "BlackHole"
$req.UseDefaultCredentials = $true

A Java String is an Object. (String extends Object.)

So you can get an Object reference via assignment/initialisation:

String a = "abc";
Object b = a;

A portable and reliable solution is to use python, which is preinstalled pretty much everywhere (including Darwin). You have two options:

1. abspath returns an absolute path but does not resolve symlinks:

   python -c "import os,sys; print(os.path.abspath(sys.argv[1]))" path/to/file

2. realpath returns an absolute path and in doing so resolves symlinks, generating a canonical path:

   python -c "import os,sys; print(os.path.realpath(sys.argv[1]))" path/to/file

In each case, path/to/file can be either a relative or absolute path.

numpy.isnan(number) tells you if it's NaN or not.

You can do this from info.plist:

1) "View controller-based status bar appearance" set to "NO"

2) "Status bar style" set to "UIStatusBarStyleLightContent"

done

You can use Random.nextInt(n). This returns a random int in [0,n). Just using max-min+1 in place of n and adding min to the answer will give a value in the desired range.

Use LayoutBuilder and Get the output you want

Wrap the SingleChildScrollView with LayoutBuilder and implement the Builder function.

we can use a LayoutBuilder to get the box contains or the amount of space available.

LayoutBuilder(
    builder: (BuildContext context, BoxConstraints constraints){
      return SingleChildScrollView(
        child: Stack(
          children: <Widget>[
            Container(
              height: constraints.maxHeight,
            ),
            topTitle(context),
            middleView(context),
            bottomView(context),
          ],
        ),
      );
    }
)

In Laravel 6 you have to add 'change' to your migrations file as follows:

org.apache.commons.lang3.StringUtils.substring(s, -7) 

gives you the answer. It returns the input if it is shorter than 7, and null if s == null. It never throws an exception.

First, you must know that you will never be able to get the source code of a page that is not on the same domain as your page in javascript. (See http://en.wikipedia.org/wiki/Same_origin_policy).

In PHP, this is how you do it:

file_get_contents($theUrl);

In javascript, there is three ways :

Firstly, by XMLHttpRequest : http://jsfiddle.net/635YY/1/

var url="../635YY",xmlhttp;//Remember, same domain
if("XMLHttpRequest" in window)xmlhttp=new XMLHttpRequest();
if("ActiveXObject" in window)xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");
xmlhttp.open('GET',url,true);
xmlhttp.onreadystatechange=function()
{
    if(xmlhttp.readyState==4)alert(xmlhttp.responseText);
};
xmlhttp.send(null);

Secondly, by iFrames : http://jsfiddle.net/XYjuX/1/

var url="../XYjuX";//Remember, same domain
var iframe=document.createElement("iframe");
iframe.onload=function()
{
    alert(iframe.contentWindow.document.body.innerHTML);
}
iframe.src=url;
iframe.style.display="none";
document.body.appendChild(iframe);

Thirdly, by jQuery : [http://jsfiddle.net/edggD/2/

$.get('../edggD',function(data)//Remember, same domain
{
    alert(data);
});

1. Create a .gitignore file in your home directory

touch ~/.gitignore

2. Add files to it (folders aren't recognised)

Example

# these work
*.gz
*.tmproj
*.7z

# these won't as they are folders
.vscode/
build/

# but you can do this
.vscode/*
build/*

3. Check if a git already has a global gitignore

git config --get core.excludesfile

4. Tell git where the file is

git config --global core.excludesfile '~/.gitignore'

Voila!!

This is a property setting rather than a valued attribute

These property settings are values per see and don't need any assignments to them. When they are present, an element has this boolean property set to true, when they're absent they're false.

<input type="text" readonly />

It's actually browsers that are liberal toward value assignment to them. If you assign any value to them it will simply get ignored. Browsers will only see the presence of a particular property and ignore the value you're trying to assign to them.

This is of course good, because some frameworks don't have the ability to add such properties without providing their value along with them. Asp.net MVC Html helpers are one of them. jQuery used to be the same until version 1.6 where they added the concept of properties.

There are of course some implications that are related to XHTML as well, because attributes in XML need values in order to be well formed. But that's a different story. Hence browsers have to ignore value assignments.

Anyway. Never mind the value you're assigning to them as long as the name is correctly spelled so it will be detected by browsers. But for readability and maintainability it's better to assign meaningful values to them like:

readonly="true" <-- arguably best human readable
readonly="readonly"

as opposed to

readonly="johndoe"
readonly="01/01/2000"

that may confuse future developers maintaining your code and may interfere with future specification that may define more strict rules to such property settings.

A short version:

$NewString = substr_replace($String,$Replacement,strrpos($String,$Replace),strlen($Replace));

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

Syntax for establishing a raw network connection using telnet is this:

telnet {domain_name} {port_number}

So telnet to your smtp server like

telnet smtp.mydomain.com 25

And copy and paste the below

helo client.mydomain.com
mail from:<[email protected]>
rcpt to:<[email protected]>
data
From: [email protected]
Subject: test mail from command line

this is test number 1

quit

Note : Do not forgot the "." at the end which represents the end of the message. The "quit" line exits ends the session.

You mentioned getting the result list from the Query, since you don't know that there is a UniqueResult (hence the exception) you could use list and check the size?

if (query.list().size() == 1) 

Since you're not doing a get() to get your unique object a query will be executed whether you call uniqueResult or list.

char* charP = createStr();

Would be correct if your function was correct. Unfortunately you are returning a pointer to a local variable in the function which means that it is a pointer to undefined data as soon as the function returns. You need to use heap allocation like malloc for the string in your function in order for the pointer you return to have any meaning. Then you need to remember to free it later.

You have 1 to 9 in the array, and you want remove 5. Use the below code:

var numberArray = [1, 2, 3, 4, 5, 6, 7, 8, 9];_x000D_
_x000D_
var newNumberArray = numberArray.filter(m => {_x000D_
  return m !== 5;_x000D_
});_x000D_
_x000D_
console.log("new Array, 5 removed", newNumberArray);

If you want to multiple values. Example:- 1,7,8

var numberArray = [1, 2, 3, 4, 5, 6, 7, 8, 9];_x000D_
_x000D_
var newNumberArray = numberArray.filter(m => {_x000D_
  return (m !== 1) && (m !== 7) && (m !== 8);_x000D_
});_x000D_
_x000D_
console.log("new Array, 1,7 and 8 removed", newNumberArray);

If you want to remove an array value in an array. Example: [3,4,5]

var numberArray = [1, 2, 3, 4, 5, 6, 7, 8, 9];_x000D_
var removebleArray = [3,4,5];_x000D_
_x000D_
var newNumberArray = numberArray.filter(m => {_x000D_
    return !removebleArray.includes(m);_x000D_
});_x000D_
_x000D_
console.log("new Array, [3,4,5] removed", newNumberArray);

Includes supported browser is link.

$start_date = new DateTime();
$start_date->setTimestamp($dbResult->db_timestamp);

I also like to wrap session variables in properties. The setters here are trivial, but I like to write the get methods so they have only one exit point. To do that I usually check for null and set it to a default value before returning the value of the session variable. Something like this:

string Name
{
   get 
   {
       if(Session["Name"] == Null)
           Session["Name"] = "Default value";
       return (string)Session["Name"];
   }
   set { Session["Name"] = value; }
}

}

Anyone wants to use command line to sync projects with gradle files, please note:

Since Gradle 5.0,

The --recompile-scripts command-line option has been removed.

I am using Android Studio 3.3.

Go to View -> Tools Window -> Device File Explorer. Or you can find it on the Bottom Right corner of the Android Studio.

If the Emulator is running, the Device File Explorer will display the File structure on Emulator Storage.

Here you can right click on a Folder and select "Upload" to place the file

This is what the official Anaconda documentation recommends:

conda update conda
conda update anaconda=2020.07

If the second line throws an error (typo in the documentation?) this worked here:

conda install anaconda=2020.07

(You can find all version specifier here.)

The command will update to a specific release of the Anaconda meta-package.

This is, IMHO, what 95% of Anaconda users want. Simply upgrading to the latest version of the Anaconda meta-package (put together and tested by the Anaconda Distributors) and not caring about the update status of individual packages (which would be issued by conda update --all).

In the case of Windows 10 this is not exactly accurate, in fact none of the answers on stackoverflow was, I found this out when I tried to use pixel art as an icon and it got rescaled when it was not supposed to(it was easy to see in this case cause of the interpolation and smoothing windows does) even thou I used the sizes from this post.

So I made an app and did the work on all DPI settings, see it here:
Windows 10 all icon resolutions on all DPI settings
You can also use my app to create icons, also with nearest neighbor interpolation with smoothing off, which is not done with any of the bad editors I have seen.

If you only want the resolutions:
16, 20, 24, 28, 30, 31, 32, 40, 42, 47, 48, 56, 60, 63, 84, 256
and you should use all PNG icons and anything you put in beside these it won't be displayed. See my post why.

Output :

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

Yes - just do it this way:

WITH DependencedIncidents AS
(
  ....
),  
lalala AS
(
  ....
)

You don't need to repeat the WITH keyword

You can just read from stdin unless the user supply a filename ?

If not, treat the special "filename" - as meaning "read from stdin". The user would have to start the program like cat file | myprogram - if he wants to pipe data to it, and myprogam file if he wants it to read from a file.

int main(int argc,char *argv[] ) {
  FILE *input;
  if(argc != 2) {
     usage();
     return 1;
   }
   if(!strcmp(argv[1],"-")) {
     input = stdin;
    } else {
      input = fopen(argv[1],"rb");
      //check for errors
    }

If you're on *nix, you can check whether stdin is a fifo:

 struct stat st_info;
 if(fstat(0,&st_info) != 0)
   //error
  }
  if(S_ISFIFO(st_info.st_mode)) {
     //stdin is a pipe
  }

Though that won't handle the user doing myprogram <file

You can also check if stdin is a terminal/console

if(isatty(0)) {
  //stdin is a terminal
}

The MSDN article lists MVC routing (the example that really clicked the concept for me) among several others. The (formatted) description paragraph reads:

• When reporting errors in code,
• hooking up model-view-controller (MVC) links,
• firing property changed events, etc.,

you often want to capture the string name of a method. Using nameof helps keep your code valid when renaming definitions.

Before you had to use string literals to refer to definitions, which is brittle when renaming code elements because tools do not know to check these string literals.

The accepted / top rated answers already give several excellent concrete examples.

I recommend XML reader/writer class for files because it is easily serialized.

Serialization in C#

Serialization (known as pickling in python) is an easy way to convert an object to a binary representation that can then be e.g. written to disk or sent over a wire.

It's useful e.g. for easy saving of settings to a file.

You can serialize your own classes if you mark them with [Serializable] attribute. This serializes all members of a class, except those marked as [NonSerialized].

The following is code to show you how to do this:

using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;


namespace ConfigTest
{ [ Serializable() ]

    public class ConfigManager
    {
        private string windowTitle = "Corp";
        private string printTitle = "Inventory";

        public string WindowTitle
        {
            get
            {
                return windowTitle;
            }
            set
            {
                windowTitle = value;
            }
        }

        public string PrintTitle
        {
            get
            {
                return printTitle;
            }
            set
            {
                printTitle = value;
            }
        }
    }
}

You then, in maybe a ConfigForm, call your ConfigManager class and Serialize it!

public ConfigForm()
{
    InitializeComponent();
    cm = new ConfigManager();
    ser = new XmlSerializer(typeof(ConfigManager));
    LoadConfig();
}

private void LoadConfig()
{     
    try
    {
        if (File.Exists(filepath))
        {
            FileStream fs = new FileStream(filepath, FileMode.Open);
            cm = (ConfigManager)ser.Deserialize(fs);
            fs.Close();
        } 
        else
        {
            MessageBox.Show("Could not find User Configuration File\n\nCreating new file...", "User Config Not Found");
            FileStream fs = new FileStream(filepath, FileMode.CreateNew);
            TextWriter tw = new StreamWriter(fs);
            ser.Serialize(tw, cm);
            tw.Close();
            fs.Close();
        }    
        setupControlsFromConfig();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

After it has been serialized, you can then call the parameters of your config file using cm.WindowTitle, etc.

Try going with Switch case or ternary operator

render(){
    return (
        <div>
            <Element1/>
            <Element2/>
            // updated code works here
            {(() => {
                        switch (this.props.hasImage) {
                            case (this.props.hasImage):
                                return <MyImage />;
                            default:
                                return (
                                   <OtherElement/>; 
                                );
                        }
                    })()}
        </div>
    )
}

This worked for me and should work for you else. Try Ternary Operator

Do not run the application using node.js icon.

Go to All Programmes->Node.js->Node.js command prompt.

Below is example screen shot.

If you are using a newer version (over 1.3.x) you should learn more about the function parseJSON! I experienced the same problem. Use an old version or change your code

success=function(data){
  //something like this
  jQuery.parseJSON(data)
}

Jasypt provides the org.jasypt.properties.EncryptableProperties class for loading, managing and transparently decrypting encrypted values in .properties files, allowing the mix of both encrypted and not-encrypted values in the same file.

http://www.jasypt.org/encrypting-configuration.html

By using an org.jasypt.properties.EncryptableProperties object, an application would be able to correctly read and use a .properties file like this:

datasource.driver=com.mysql.jdbc.Driver 
datasource.url=jdbc:mysql://localhost/reportsdb 
datasource.username=reportsUser 
datasource.password=ENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm) 

Note that the database password is encrypted (in fact, any other property could also be encrypted, be it related with database configuration or not).

How do we read this value? like this:

/*
* First, create (or ask some other component for) the adequate encryptor for   
* decrypting the values in our .properties file.   
*/  
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();     
encryptor.setPassword("jasypt"); // could be got from web, env variable...    
/*   
* Create our EncryptableProperties object and load it the usual way.   
*/  
Properties props = new EncryptableProperties(encryptor);  
props.load(new FileInputStream("/path/to/my/configuration.properties"));

/*   
* To get a non-encrypted value, we just get it with getProperty...   
*/  
String datasourceUsername = props.getProperty("datasource.username");

/*   
* ...and to get an encrypted value, we do exactly the same. Decryption will   
* be transparently performed behind the scenes.   
*/ 
String datasourcePassword = props.getProperty("datasource.password");

 // From now on, datasourcePassword equals "reports_passwd"...

Based on the Microsoft support KBs, this can occur if TCP/IP is damaged or is not bound to your dial-up adapter.You can try reinstalling or resetting TCP/IP as follows:

• Reset TCP/IP to Original Configuration- Using the NetShell utility, type this command (in CommandLine): netsh int ip reset [file_name.txt], [file_name.txt] is the name of the file where the actions taken by NetShell are record, for example netsh hint ip reset fixtcpip.txt.

• Remove and re-install NIC – Open Controller and select System. Click Hardware tab and select devices. Double-click on Network Adapter and right-click on the NIC, select Uninstall. Restart the computer and the Windows should auto detect the NIC and re-install it.

• Upgrade the NIC driver – You may download the latest NIC driver and upgrade the driver.

Hope it could help.

The locks are always taken at DB level:-

Oracle official Document:- To avoid conflicts during a transaction, a DBMS uses locks, mechanisms for blocking access by others to the data that is being accessed by the transaction. (Note that in auto-commit mode, where each statement is a transaction, locks are held for only one statement.) After a lock is set, it remains in force until the transaction is committed or rolled back. For example, a DBMS could lock a row of a table until updates to it have been committed. The effect of this lock would be to prevent a user from getting a dirty read, that is, reading a value before it is made permanent. (Accessing an updated value that has not been committed is considered a dirty read because it is possible for that value to be rolled back to its previous value. If you read a value that is later rolled back, you will have read an invalid value.)

How locks are set is determined by what is called a transaction isolation level, which can range from not supporting transactions at all to supporting transactions that enforce very strict access rules.

One example of a transaction isolation level is TRANSACTION_READ_COMMITTED, which will not allow a value to be accessed until after it has been committed. In other words, if the transaction isolation level is set to TRANSACTION_READ_COMMITTED, the DBMS does not allow dirty reads to occur. The interface Connection includes five values that represent the transaction isolation levels you can use in JDBC.

In case its useful or a better way:

str = str.replace(/(\s*,?\s*)*$/, "");

It will replace all following combination end of the string:

1. ,<no space>
2. ,<spaces> 
3. ,  ,  , ,   ,
4. <spaces>
5. <spaces>,
6. <spaces>,<spaces>

There are plenty available. Try using Modal windows of Jquery or DHTML would do good. Put the content in your div or Change your content in div dynamically and show it to the user. It won't be a popup but a modal window.
Jquery's Thickbox would clear your problem.

If you are familiar with iptables service like in centos 6 or earlier, you can still use iptables service by manual installation:

step 1 => install epel repo

yum install epel-release

step 2 => install iptables service

yum install iptables-services

step 3 => stop firewalld service

systemctl stop firewalld

step 4 => disable firewalld service on startup

systemctl disable firewalld

step 5 => start iptables service

systemctl start iptables

step 6 => enable iptables on startup

systemctl enable iptables

finally you're now can editing your iptables config at /etc/sysconfig/iptables.

So -> edit rule -> reload/restart.

do like older centos with same function like firewalld.

I had the same problem. If I add one Environment.Newline I get one new line in the textbox. But if I add two Environment.Newline I get one new line. In my web app I use a whitespace modul that removes all unnecessary white spaces. If i disable this module I get two new lines in my textbox. Hope that helps.

%pip install fedex    #fedex = package name

in 2019.

In older versions of conda:

import sys
!{sys.executable} -m pip install fedex     #fedex = package name

*note - you do need to import sys

Woff is a compressed (zipped) form of the TrueType - OpenType font. It is small and can be delivered over the network like a graphic file. Most importantly, this way the font is preserved completely including rendering rule tables that very few people care about because they use only Latin script.

Take a look at [dead URL removed]. The font you see is an experimental web delivered smartfont (woff) that has thousands of combined characters making complex shapes. The underlying text is simple Latin code of romanized Singhala. (Copy and paste to Notepad and see).

Only woff can do this because nobody has this font and yet it is seen anywhere (Mac, Win, Linux and even on smartphones by all browsers except by IE. IE does not have full support for Open Types).

Looks like you can construct the link to the NDK that you want and download it from dl.google.com:

Linux example:

OS X example:
http://dl.google.com/android/ndk/android-ndk-r9b-darwin-x86.tar.bz2 http://dl.google.com/android/ndk/android-ndk-r9b-darwin-x86_64.tar.bz2

Windows example:
http://dl.google.com/android/ndk/android-ndk-r9b-windows.zip

Extensions up to r10b:
.tar.bz2 for linux / os x and .zip for windows.

Since r10c the extensions have changed to:
.bin for linux / os x and .exe for windows

Since r11:

.zip for linux and OS X as well, a new URL base, and no 32 bit versions for OS X and linux.

Your error

InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

appears because you must call setRequestHeader after calling open. Simply move your setRequestHeader line below your open line (but before send):

xmlhttp.open("POST", url);
xmlhttp.setRequestHeader("x-filename", photoId);
xmlhttp.send(formData);

Iterate through...

• ...files in current dir: for %f in (.\*) do @echo %f

• ...subdirs in current and all subdirs: for /R /D %s in (.\*) do @echo %s

Unfortunately I did not find any way to iterate over files and subdirs at the same time.

Just use cygwin with its bash for much more functionality.

if (CollectionUtils.isNotEmpty(listName))

Is the same as:

if(listName != null && !listName.isEmpty())

In first approach listName can be null and null pointer exception will not be thrown. In second approach you have to check for null manually. First approach is better because it requires less work from you. Using .size() != 0 is something unnecessary at all, also i learned that it is slower than using .isEmpty()

import numpy as np
import scipy.stats


def mean_confidence_interval(data, confidence=0.95):
    a = 1.0 * np.array(data)
    n = len(a)
    m, se = np.mean(a), scipy.stats.sem(a)
    h = se * scipy.stats.t.ppf((1 + confidence) / 2., n-1)
    return m, m-h, m+h

you can calculate like this way.

The only way to know for sure is to benchmark it, and even that is not as simple as it may sound. The JIT compiler can do very unexpected things to your code.

Solved: The problem lies here:

I set POST via both _CUSTOMREQUEST and _POST and the _CUSTOMREQUEST persisted as POST while _POST switched to _HTTPGET. The Server assumed the header from _CUSTOMREQUEST to be the right one and came back with a 411.

curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'POST');

Here is an example using RSA.

Important: There is a limit to the size of data you can encrypt with the RSA encryption, KeySize - MinimumPadding. e.g. 256 bytes (assuming 2048 bit key) - 42 bytes (min OEAP padding) = 214 bytes (max plaintext size)

Replace your_rsa_key with your RSA key.

var provider = new System.Security.Cryptography.RSACryptoServiceProvider();
provider.ImportParameters(your_rsa_key);

var encryptedBytes = provider.Encrypt(
    System.Text.Encoding.UTF8.GetBytes("Hello World!"), true);

string decryptedTest = System.Text.Encoding.UTF8.GetString(
    provider.Decrypt(encryptedBytes, true));

This is a variation to the answer provided by @Metrics and edited by @Max Ghenis...

l <- sapply(iris, function(x) is.factor(x))
m <- iris[,l]

n <- sapply( m, function(x) { y <- summary(x)/length(x)
len <- length(y[y<0.005 | y>0.995])
cbind(len,t(y))} )

drop_cols_df <- data.frame(var = names(l[l]), 
                           status = ifelse(as.vector(t(n[1,]))==0,"NODROP","DROP" ),
                           level1 = as.vector(t(n[2,])),
                           level2 = as.vector(t(n[3,])))

Here, after identifying factor variables, the second sapply computes what percent of records belong to each level / category of the variable. Then it identifies number of levels over 99.5% or below 0.5% incidence rate (my arbitrary thresholds).

It then goes on to return the number of valid levels and the incidence rate of each level in each categorical variable.

Variables with zero levels crossing the thresholds should not be dropped, while the other should be dropped from the linear model.

The last data frame makes viewing the results easy. It's hard coded for this data set since all factor variables are binomial. This data frame can be made generic easily enough.

You must use 'gem uninstall gem_name' to uninstall a gem.

Note that if you installed the gem system-wide (ie. sudo bundle install) then you may need to specify the binary directory using the -n option, to ensure binaries belonging to the gem are removed. For example

sudo gem uninstall gem_name  -n /usr/lib/ruby/gems/1.9.1/bin

Just use the formatting with %.2f which gives you rounding down to 2 decimals.

def printC(answer):
    print "\nYour Celsius value is %.2f C.\n" % answer

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

First up let me start by saying why we need a database.

We need a database to help organise information in such a manner that we can retrieve that data stored in a efficient manner.

Examples of relational database management systems(SQL):

1)Oracle Database

2)SQLite

3)PostgreSQL

4)MySQL

5)Microsoft SQL Server

6)IBM DB2

Examples of non relational database management systems(NoSQL)

1)MongoDB

2)Cassandra

3)Redis

4)Couchbase

5)HBase

6)DocumentDB

7)Neo4j

Relational databases have normalized data, as in information is stored in tables in forms of rows and columns, and normally when data is in normalized form, it helps to reduce data redundancy, and the data in tables are normally related to each other, so when we want to retrieve the data, we can query the data by using join statements and retrieve data as per our need.This is suited when we want to have more writes, less reads, and not much data involved, also its really easy relatively to update data in tables than in non relational databases. Horizontal scaling not possible, vertical scaling possible to some extent.CAP(Consistency, Availability, Partition Tolerant), and ACID (Atomicity, Consistency, Isolation, Duration)compliance.

Let me show entering data to a relational database using PostgreSQL as an example.

First create a product table as follows:

CREATE TABLE products (
    product_no integer,
    name text,
    price numeric
);

then insert the data

INSERT INTO products (product_no, name, price) VALUES (1, 'Cheese', 9.99);

Let's look at another different example:

Here in a relational database, we can link the student table and subject table using relationships, via foreign key, subject ID, but in a non relational database no need to have two documents, as no relationships, so we store all the subject details and student details in one document say student document, then data is getting duplicated, which makes updating records troublesome.

In non relational databases, there is no fixed schema, data is not normalized. no relationships between data is created, all data mostly put in one document. Well suited when handling lots of data, and can transfer lots of data at once, best where high amounts of reads and less writes, and less updates, bit difficult to query data, as no fixed schema. Horizontal and vertical scaling is possible.CAP (Consistency, Availability, Partition Tolerant)and BASE (Basically Available, soft state, Eventually consistent)compliance.

Let me show an example to enter data to a non relational database using Mongodb

db.users.insertOne({name: ‘Mary’, age: 28 , occupation: ‘writer’ })
db.users.insertOne({name: ‘Ben’ , age: 21})

Hence you can understand that to the database called db, and there is a collections called users, and document called insertOne to which we add data, and there is no fixed schema as our first record has 3 attributes, and second attribute has 2 attributes only, this is no problem in non relational databases, but this cannot be done in relational databases, as relational databases have a fixed schema.

Let's look at another different example

({Studname: ‘Ash’, Subname: ‘Mathematics’, LecturerName: ‘Mr. Oak’})

Hence we can see in non relational database we can enter both student details and subject details into one document, as no relationships defined in non relational databases, but here this way can lead to data duplication, and hence errors in updating can occur therefore.

Hope this explains everything

I could not find a solution to what I was looking for so I created some custom functions. You can try them out.

There is a built-in way to format LocalDate in Joda library

import org.joda.time.LocalDate;

LocalDate localDate = LocalDate.now();
String dateFormat = "MM/dd/yyyy";
localDate.toString(dateFormat);

In case you don't have it already - add this to the build.gradle:

implementation 'joda-time:joda-time:2.9.5'

Happy coding! :)

If I understand correctly, you want to have one class implement multiple of those interfaces with different input/output parameters? This will not work in Java, because the generics are implemented via erasure.

The problem with the Java generics is that the generics are in fact nothing but compiler magic. At runtime, the classes do not keep any information about the types used for generic stuff (class type parameters, method type parameters, interface type parameters). Therefore, even though you could have overloads of specific methods, you cannot bind those to multiple interface implementations which differ in their generic type parameters only.

In general, I can see why you think that this code has a smell. However, in order to provide you with a better solution, it would be necessary to know a little more about your requirements. Why do you want to use a generic interface in the first place?

HTTP Solution

From the documentation, "the right way is to define a separate server for example.org":

server {
    listen       80;
    server_name  example.com;
    return       301 http://www.example.com$request_uri;
}

server {
    listen       80;
    server_name  www.example.com;
    ...
}

HTTPS Solution

For those who want a solution including https://...

server {
        listen 80;
        server_name www.domain.com;
        # $scheme will get the http protocol
        # and 301 is best practice for tablet, phone, desktop and seo
        return 301 $scheme://domain.com$request_uri;
}

server {
        listen 80;
        server_name domain.com;
        # here goes the rest of your config file
        # example 
        location / {

            rewrite ^/cp/login?$ /cp/login.php last;
            # etc etc...

        }
}

Note: I have not originally included https:// in my solution since we use loadbalancers and our https:// server is a high-traffic SSL payment server: we do not mix https:// and http://.

To check the nginx version, use nginx -v.

Strip www from url with nginx redirect

server {
    server_name  www.domain.com;
    rewrite ^(.*) http://domain.com$1 permanent;
}

server {
    server_name  domain.com;
    #The rest of your configuration goes here#
}

So you need to have TWO server codes.

Add the www to the url with nginx redirect

If what you need is the opposite, to redirect from domain.com to www.domain.com, you can use this:

server {
    server_name  domain.com;
    rewrite ^(.*) http://www.domain.com$1 permanent;
}

server {
    server_name  www.domain.com;
    #The rest of your configuration goes here#
}

As you can imagine, this is just the opposite and works the same way the first example. This way, you don't get SEO marks down, as it is complete perm redirect and move. The no WWW is forced and the directory shown!

Some of my code shown below for a better view:

server {
    server_name  www.google.com;
    rewrite ^(.*) http://google.com$1 permanent;
}
server {
       listen 80;
       server_name google.com;
       index index.php index.html;
       ####
       # now pull the site from one directory #
       root /var/www/www.google.com/web;
       # done #
       location = /favicon.ico {
                log_not_found off;
                access_log off;
       }
}

You can filter by multiple columns (more than two) by using the np.logical_and operator to replace & (or np.logical_or to replace |)

Here's an example function that does the job, if you provide target values for multiple fields. You can adapt it for different types of filtering and whatnot:

def filter_df(df, filter_values):
    """Filter df by matching targets for multiple columns.

    Args:
        df (pd.DataFrame): dataframe
        filter_values (None or dict): Dictionary of the form:
                `{<field>: <target_values_list>}`
            used to filter columns data.
    """
    import numpy as np
    if filter_values is None or not filter_values:
        return df
    return df[
        np.logical_and.reduce([
            df[column].isin(target_values) 
            for column, target_values in filter_values.items()
        ])
    ]

Usage:

df = pd.DataFrame({'a': [1, 2, 3, 4], 'b': [1, 2, 3, 4]})

filter_df(df, {
    'a': [1, 2, 3],
    'b': [1, 2, 4]
})

To remove you tube controls and title you can do something like this

<iframe width="560" height="315" src="https://www.youtube.com/embed/zP0Wnb9RI9Q?autoplay=1&showinfo=0&controls=0" frameborder="0" allowfullscreen ></iframe>

code with output

showinfo=0 is used to remove title and &controls=0 is used for remove controls like volume,play,pause,expend.

If you have a text as

var sampleText ="ä_öü_ßÄ_ TESTED Ö_Ü!@#$%^&())(&&++===.XYZ"

To replace all special character (!@#$%^&())(&&++= ==.) without replacing the characters(including umlaut)

Use below regex

sampleText = sampleText.replace(/[`~!@#$%^&*()|+-=?;:'",.<>{}[]\/\s]/gi,'');

OUTPUT : sampleText = "ä_öü_ßÄ____TESTED_Ö_Ü_____________________XYZ"

This would replace all with an underscore which is provided as second argument to the replace function.You can add whatever you want as per your requirement

It has been almost 8 years since the question was asked, but I will venture an answer not previously given. The OP said this doesn't work:

action="javascript:simpleCart.checkout()"

And the OP said that this code continued to fail despite trying all the good advice he got. So I will venture a guess. The action is calling checkout() as a static method of the simpleCart class; but maybe checkout() is actually an instance member, and not static. It depends how he defined checkout().

By the way, simpleCart is presumably a class name, and by convention class names have an initial capital letter, so let's use that convention, here. Let's use the name SimpleCart.

Here is some sample code that illustrates defining checkout() as an instance member. This was the correct way to do it, prior to ECMA-6:

function SimpleCart() {
    ...
}
SimpleCart.prototype.checkout = function() { ... };

Many people have used a different technique, as illustrated in the following. This was popular, and it worked, but I advocate against it, because instances are supposed to be defined on the prototype, just once, while the following technique defines the member on this and does so repeatedly, with every instantiation.

function SimpleCart() {
    ...
    this.checkout = function() { ... };
}

And here is an instance definition in ECMA-6, using an official class:

class SimpleCart {
    constructor() { ... }
    ...
    checkout()    { ... }
}

Compare to a static definition in ECMA-6. The difference is just one word:

class SimpleCart {
    constructor() { ... }
    ...
    static checkout()    { ... }
}

And here is a static definition the old way, pre-ECMA-6. Note that the checkout() method is defined outside of the function. It is a member of the function object, not the prototype object, and that's what makes it static.

function SimpleCart() {
    ...
}
SimpleCart.checkout = function() { ... };

Because of the way it is defined, a static function will have a different concept of what the keyword this references. Note that instance member functions are called using the this keyword:

this.checkout();

Static member functions are called using the class name:

SimpleCart.checkout();

The problem is that the OP wants to put the call into HTML, where it will be in global scope. He can't use the keyword this because this would refer to the global scope (which is window).

action="javascript:this.checkout()" // not as intended
action="javascript:window.checkout()" // same thing

There is no easy way to use an instance member function in HTML. You can do stuff in combination with JavaScript, creating a registry in the static scope of the Class, and then calling a surrogate static method, while passing an argument to that surrogate that gives the index into the registry of your instance, and then having the surrogate call the actual instance member function. Something like this:

// In Javascript:
SimpleCart.registry[1234] = new SimpleCart();

// In HTML
action="javascript:SimpleCart.checkout(1234);"

// In Javascript
SimpleCart.checkout = function(myIndex) {
    var myThis = SimpleCart.registry[myIndex];
    myThis.checkout();
}

You could also store the index as an attribute on the element.

But usually it is easier to just do nothing in HTML and do everything in JavaScript with .addEventListener() and use the .bind() capability.

I was playing around with the following code for another question on StackOverflow and thought that it might be appropriate for here. The function printList2 allows the use of a regex and lists all the occurrences in order. (printList was an attempt at an earlier solution, but it failed in a number of cases.)

From the documentations:

Add the support library to the dependencies section. For example, to add the v4 core-utils library, add the following lines:

dependencies {
    ...
    implementation "com.android.support:support-core-utils:28.0.0"
}

If you have a self-signed certificate generated by makecert.exe on a Windows machine, you will get two files: cert.pvk and cert.cer. These can be converted to a pfx using pvk2pfx

pvk2pfx is found in the same location as makecert (e.g. C:\Program Files (x86)\Windows Kits\10\bin\x86 or similar)

pvk2pfx -pvk cert.pvk -spc cert.cer -pfx cert.pfx

The general problem here is that git fetch will fetch +refs/heads/*:refs/remotes/$remote/*. If any of these commits have tags, those tags will also be fetched. However if there are tags not reachable by any branch on the remote, they will not be fetched.

The --tags option switches the refspec to +refs/tags/*:refs/tags/*. You could ask git fetch to grab both. I'm pretty sure to just do a git fetch && git fetch -t you'd use the following command:

git fetch origin "+refs/heads/*:refs/remotes/origin/*" "+refs/tags/*:refs/tags/*"

And if you wanted to make this the default for this repo, you can add a second refspec to the default fetch:

git config --local --add remote.origin.fetch "+refs/tags/*:refs/tags/*"

This will add a second fetch = line in the .git/config for this remote.

I spent a while looking for the way to handle this for a project. This is what I came up with.

git fetch -fup origin "+refs/*:refs/*"

In my case I wanted these features

• Grab all heads and tags from the remote so use refspec refs/*:refs/*
• Overwrite local branches and tags with non-fast-forward + before the refspec
• Overwrite currently checked out branch if needed -u
• Delete branches and tags not present in remote -p
• And force to be sure -f

I came across the same problem, but I wasn't enamoured by any of the solutions I found here. So, I wrote one that iterates over the characters of the string using a matcher to find and replace the escape sequences. This solution assumes properly formatted input. That is, it happily skips over nonsensical escapes, and it decodes Unicode escapes for line feed and carriage return (which otherwise cannot appear in a character literal or a string literal, due to the definition of such literals and the order of translation phases for Java source). Apologies, the code is a bit packed for brevity.

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

public class Decoder {

    // The encoded character of each character escape.
    // This array functions as the keys of a sorted map, from encoded characters to decoded characters.
    static final char[] ENCODED_ESCAPES = { '\"', '\'', '\\',  'b',  'f',  'n',  'r',  't' };

    // The decoded character of each character escape.
    // This array functions as the values of a sorted map, from encoded characters to decoded characters.
    static final char[] DECODED_ESCAPES = { '\"', '\'', '\\', '\b', '\f', '\n', '\r', '\t' };

    // A pattern that matches an escape.
    // What follows the escape indicator is captured by group 1=character 2=octal 3=Unicode.
    static final Pattern PATTERN = Pattern.compile("\\\\(?:(b|t|n|f|r|\\\"|\\\'|\\\\)|((?:[0-3]?[0-7])?[0-7])|u+(\\p{XDigit}{4}))");

    public static CharSequence decodeString(CharSequence encodedString) {
        Matcher matcher = PATTERN.matcher(encodedString);
        StringBuffer decodedString = new StringBuffer();
        // Find each escape of the encoded string in succession.
        while (matcher.find()) {
            char ch;
            if (matcher.start(1) >= 0) {
                // Decode a character escape.
                ch = DECODED_ESCAPES[Arrays.binarySearch(ENCODED_ESCAPES, matcher.group(1).charAt(0))];
            } else if (matcher.start(2) >= 0) {
                // Decode an octal escape.
                ch = (char)(Integer.parseInt(matcher.group(2), 8));
            } else /* if (matcher.start(3) >= 0) */ {
                // Decode a Unicode escape.
                ch = (char)(Integer.parseInt(matcher.group(3), 16));
            }
            // Replace the escape with the decoded character.
            matcher.appendReplacement(decodedString, Matcher.quoteReplacement(String.valueOf(ch)));
        }
        // Append the remainder of the encoded string to the decoded string.
        // The remainder is the longest suffix of the encoded string such that the suffix contains no escapes.
        matcher.appendTail(decodedString);
        return decodedString;
    }

    public static void main(String... args) {
        System.out.println(decodeString(args[0]));
    }
}

I should note that Apache Commons Lang3 doesn't seem to suffer the weaknesses indicated in the accepted solution. That is, StringEscapeUtils seems to handle octal escapes and multiple u characters of Unicode escapes. That means unless you have some burning reason to avoid Apache Commons, you should probably use it rather than my solution (or any other solution here).

>>> average =  [1,3,2,1,1,0,24,23,7,2,727,2,7,68,7,83,2]
>>> matches = [i for i in range(0,len(average)) if average[i]<2 or average[i]>4]
>>> matches
[0, 3, 4, 5, 6, 7, 8, 10, 12, 13, 14, 15]

javac -version in a terminal will do

Quite simple with a closure:

def map = [
           'iPhone':'iWebOS',
           'Android':'2.3.3',
           'Nokia':'Symbian',
           'Windows':'WM8'
           ]

map.each{ k, v -> println "${k}:${v}" }

If you've recently updated, a reboot might solve this problem.

apt-get install python-setuptools python-pip

or

apt-get install python3-setuptools python3-pip

you'd also want to install the python packages...

It's PHP where the string "0" is falsy (false-when-used-in-boolean-context). In JavaScript, all non-empty strings are truthy.

The trick is that == against a boolean doesn't evaluate in a boolean context, it converts to number, and in the case of strings that's done by parsing as decimal. So you get Number 0 instead of the truthiness boolean true.

This is a really poor bit of language design and it's one of the reasons we try not to use the unfortunate == operator. Use === instead.

Either way gets the job done. I assume that by zigzag you mean something like this: (numbers are order of rendering)

..  ..  01  ..  ..
  ..  06  02  ..
..  11  07  03  ..
  16  12  08  04
21  17  13  09  05
  22  18  14  10
..  23  19  15  ..
  ..  24  20  ..
..  ..  25  ..  ..

And by diamond you mean:

..  ..  ..  ..  ..
  01  02  03  04
..  05  06  07  ..
  08  09  10  11
..  12  13  14  ..
  15  16  17  18
..  19  20  21  ..
  22  23  24  25
..  ..  ..  ..  ..

The first method needs more tiles rendered so that the full screen is drawn, but you can easily make a boundary check and skip any tiles fully off-screen. Both methods will require some number crunching to find out what is the location of tile 01. In the end, both methods are roughly equal in terms of math required for a certain level of efficiency.

FileUtils is class from apache org.apache.commons.io package, you need to download org.apache.commons.io.jar and then configure that jar file in your class path.

The other answers and comments covered table renaming, file renaming, and grepping through your code.

I'd like to add a few more caveats:

Let's use a real-world example I faced today: renaming a model from 'Merchant' to 'Business.'

• Don't forget to change the names of dependent tables and models in the same migration. I changed my Merchant and MerchantStat models to Business and BusinessStat at the same time. Otherwise I'd have had to do way too much picking and choosing when performing search-and-replace.
• For any other models that depend on your model via foreign keys, the other tables' foreign-key column names will be derived from your original model name. So you'll also want to do some rename_column calls on these dependent models. For instance, I had to rename the 'merchant_id' column to 'business_id' in various join tables (for has_and_belongs_to_many relationship) and other dependent tables (for normal has_one and has_many relationships). Otherwise I would have ended up with columns like 'business_stat.merchant_id' pointing to 'business.id'. Here's a good answer about doing column renames.
• When grepping, remember to search for singular, plural, capitalized, lowercase, and even UPPERCASE (which may occur in comments) versions of your strings.
• It's best to search for plural versions first, then singular. That way if you have an irregular plural - such as in my merchants :: businesses example - you can get all the irregular plurals correct. Otherwise you may end up with, for example, 'businesss' (3 s's) as an intermediate state, resulting in yet more search-and-replace.
• Don't blindly replace every occurrence. If your model names collide with common programming terms, with values in other models, or with textual content in your views, you may end up being too over-eager. In my example, I wanted to change my model name to 'Business' but still refer to them as 'merchants' in the content in my UI. I also had a 'merchant' role for my users in CanCan - it was the confusion between the merchant role and the Merchant model that caused me to rename the model in the first place.

Click on options on the connect to Server dialog and on the Connection Properties, you can choose the database to connect to on startup. Its better to leave it default which will make master as default. Otherwise you might inadvertently run sql on a wrong database after connecting to a database.

For Db2 for Linux, Unix and Windows (i.e. Db2 LUW) or for Db2 Warehouse use the SYSCAT.TABLES catalog view. E.g.

SELECT TABSCHEMA, TABNAME FROM SYSCAT.TABLES WHERE TABSCHEMA LIKE '%CUR%' AND TYPE = 'T'

Which is a SQL statement that will return all standard tables in all schema that contains the substring CUR. From a Db2 command line you could also use a CLP command e.g. db2 list tables for all | grep CUR to similar effect

This page describes the columns in SYSCAT.TABLES including the different values for the TYPE column.

A = Alias
G = Created temporary table
H = Hierarchy table
L = Detached table
N = Nickname
S = Materialized query table
T = Table (untyped)
U = Typed table
V = View (untyped)
W = Typed view

Other commonly used catalog views incude

SYSCAT.COLUMNS      Lists the columns in each table, view and nickname
SYSCAT.VIEWS        Full SQL text for view and materialized query tables
SYSCAT.KEYCOLUSE    Column that are in PK, FK or Uniuqe constraints

In Db2 LUW it is considered bad practice to use the SYSIBM catalog tables (which the SYSCAT catalog views select thier data from). They are less consistent as far as column names go, are not quite as easy to use, are not documented and are more likely to change between versions.

This page has a list of all the catalog views Road map to the catalog views

For Db2 for z/OS, use SYSIBM.TABLES which is described here. E.g.

SELECT CREATOR, NAME FROM SYSIBM.SYSTABLES WHERE OWNER LIKE '%CUR%' AND TYPE = 'T'

For Db2 for i (i.e. iSeries aka AS/400) use QSYS2.SYSTABLES which is described here

SELECT TABLE_OWNER, TABLE_NAME FROM QSYS2.SYSTABLES WHERE TABLE_SCHEMA LIKE '%CUR%' AND TABLE_TYPE = 'T'

For DB2 Server for VSE and VM use SYSTEM.SYSCATALOG which is described here DB2 Server for VSE and VM SQL Reference

SELECT CREATOR, TNAME FROM SYSTEM.SYSCATALOG WHERE TABLETYPE = 'R'

Here is an example for Python 3 that you can edit for Python 2 ;)

from tkinter import *
from PIL import ImageTk, Image
from tkinter import filedialog
import os

root = Tk()
root.geometry("550x300+300+150")
root.resizable(width=True, height=True)

def openfn():
    filename = filedialog.askopenfilename(title='open')
    return filename
def open_img():
    x = openfn()
    img = Image.open(x)
    img = img.resize((250, 250), Image.ANTIALIAS)
    img = ImageTk.PhotoImage(img)
    panel = Label(root, image=img)
    panel.image = img
    panel.pack()

btn = Button(root, text='open image', command=open_img).pack()

root.mainloop()

If none of these solutions are clearing an image you've already set (especially setImageResource(0) or setImageResources(android.R.color.transparent), check to make sure the current image isn't set as background using setBackgroundDrawable(...) or something similar.

Your code will just set the image resource in the foreground to something transparent in front of that background image you've set and will still show.

The problem is that omega in your case is matrix of dimensions 1 * 1. You should convert it to a vector if you wish to multiply t(X) %*% X by a scalar (that is omega)

In particular, you'll have to replace this line:

omega   = rgamma(1,a0,1) / L0

with:

omega   = as.vector(rgamma(1,a0,1) / L0)

everywhere in your code. It happens in two places (once inside the loop and once outside). You can substitute as.vector(.) or c(t(.)). Both are equivalent.

Here's the modified code that should work:

gibbs = function(data, m01 = 0, m02 = 0, k01 = 0.1, k02 = 0.1, 
                     a0 = 0.1, L0 = 0.1, nburn = 0, ndraw = 5000) {
    m0      = c(m01, m02) 
    C0      = matrix(nrow = 2, ncol = 2) 
    C0[1,1] = 1 / k01 
    C0[1,2] = 0

Most of these answers are out of date. JsonResponse is not recommended because it escapes the characters, which is usually undesired. Here's what I use:

views.py (returns HTML)

from django.shortcuts import render
from django.core import serializers

def your_view(request):
    data = serializers.serialize('json', YourModel.objects.all())
    context = {"data":data}
    return render(request, "your_view.html", context)

views.py (returns JSON)

from django.core import serializers
from django.http import HttpResponse

def your_view(request):
    data = serializers.serialize('json', YourModel.objects.all())
    return HttpResponse(data, content_type='application/json')

Bonus for Vue Users

If you want to bring your Django Queryset into Vue, you can do the following.

template.html

<div id="dataJson" style="display:none">
{{ data }}
</div>

<script>
let dataParsed = JSON.parse(document.getElementById('dataJson').textContent);
var app = new Vue({
  el: '#app',
  data: {
    yourVariable: dataParsed,
  },
})
</script>

malloc does not allocate on specific boundaries, so it must be assumed that it allocates on a byte boundary.

The returned pointer can then not be used if converted to any other type, since accessing that pointer will probably produce a memory access violation by the CPU, and the application will be immediately shut down.

I've just had the same problem and found a different solution. I was getting

error: There was a problem with the editor 'ec'

I've got VISUAL=ec, and a batch file called ec.bat on my path that contains one line:

c:\emacs\emacs-23.1\bin\emacsclient.exe %*

This lets me edit files from the command line with ec <filename>, and having VISUAL set means most unixy programs pick it up too. Git seems to search the path differently to my other commands though - when I looked at a git commit in Process Monitor I saw it look in every folder on the path for ec and for ec.exe, but not for ec.bat. I added another environment variable (GIT_EDITOR=ec.bat) and all was fine.

You can add a shebang line the to the top of the script:

#!/usr/bin/env python2.7

But that will only work when executing as ./my_program.py.

If you execute as python my_program.py, then the whatever Python version that which python returns will be used.

In re: to virtualenv use: virtualenv -p /usr/bin/python3.2 or whatever to set it up to use that Python executable.

See ?boxplot for all the help you need.

 outline: if ‘outline’ is not true, the outliers are not drawn (as
          points whereas S+ uses lines).

boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)

And for extending the range of the whiskers and suppressing the outliers inside this range:

   range: this determines how far the plot whiskers extend out from the
          box.  If ‘range’ is positive, the whiskers extend to the most
          extreme data point which is no more than ‘range’ times the
          interquartile range from the box. A value of zero causes the
          whiskers to extend to the data extremes.

# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)

I had issues with all mentioned answers, except with solution i did myself: Container(width: MediaQuery.of(context).size.width, height: MediaQuery.of(context).padding.top, color: Colors.green) For views, where is no appBar added i just use container with background which exact height matches status bar height. In this scenario each view can have different status color and i don't need to worry and think about some logic, that somehow wrong views has somehow wrong colors.

It's deprecated but it still works so you could just use it. But if you want to be completly correct, just for the completeness of it... You'd do something like following:

int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    setBackgroundDrawable();
} else {
    setBackground();
}

For this to work you need to set buildTarget api 16 and min build to 7 or something similar.

It is better to use onchange(event) with <select>. With <input> you can use below event:

- onkeyup(event)
- onkeydown(event)
- onkeypress(event)

Traditionally whenever I've wanted to commit and empty directory structure, I create the structure and then in the leaf directories place an empty file called empty.txt.

Then when I put stuff in that's ready to commit, I can simply remove the empty.txt file and commit the real files.

i.e.

• data/
  • images/
    • empty.txt

If you want to add the value on aspx page , Just enter <a href='your link'>clickhere</a>

If you are trying to achieve it via Code-Behind., Make use of the Hyperlink control

HyperLink hl1 = new HyperLink();
hl1.text="Click Here";
hl1.NavigateUrl="http://www.stackoverflow.com";

For a nice looking screencast, have a look at SimFinger. You will still need a screen recoder such as Snapz Pro.

Note that the if $myVar; then ... ;fi construct has a security problem you might want to avoid with

case $myvar in
  (true)    echo "is true";;
  (false)   echo "is false";;
  (rm -rf*) echo "I just dodged a bullet";;
esac

You might also want to rethink why if [ "$myvar" = "true" ] appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case solution is also handled without forks.

Modify the package you're using:

import org.apache.commons.codec.binary.Base64;

And then use it like this:

byte[] decoded = Base64.decodeBase64("YWJjZGVmZw==");
System.out.println(new String(decoded, "UTF-8") + "\n");

Normally beans are POJO, so they have accessors anyway.

So the question is not "which one is better?", but simply "when to use field access?". And the answer is "when you don't need a setter/getter for the field!".

You can run easy_install to install python packages in your home directory even without root access. There's a standard way to do this using site.USER_BASE which defaults to something like $HOME/.local or $HOME/Library/Python/2.7/bin and is included by default on the PYTHONPATH

To do this, create a .pydistutils.cfg in your home directory:

cat > $HOME/.pydistutils.cfg <<EOF
[install]
user=1
EOF

Now you can run easy_install without root privileges:

easy_install boto

Alternatively, this also lets you run pip without root access:

pip install boto

This works for me.

First i tried with this sample code:

$(document).ready(function(){ 
     $('#upload-file').click(); 
});

It didn't work for me. Then after, tried with this

$(document).ready(function(){ 
     $('#upload-file')[0].click(); 
});

No change. At last, tried with this

$(document).ready(function(){ 
     $('#upload-file')[0].click(function(){
     }); 
});

Solved my problem. Helpful for anyone.

One thing you could do is:

$date.ToString("yyyyMMdd")

Here's another way through the GUI that does exactly what your script does even though it goes through Indexes (not Constraints) in the object explorer.

1. Right click on "Indexes" and click "New Index..." (note: this is disabled if you have the table open in design view)

2. Give new index a name ("U_Name"), check "Unique", and click "Add..."

3. Select "Name" column in the next windown

4. Click OK in both windows

dict((k, v) for k, v in points.items() if all(x < 5 for x in v))

You could choose to call .iteritems() instead of .items() if you're in Python 2 and points may have a lot of entries.

all(x < 5 for x in v) may be overkill if you know for sure each point will always be 2D only (in that case you might express the same constraint with an and) but it will work fine;-).

What I did was to use SimpleDateFormat to create a format string, and parse the text to a date, and then retrieve the month from that. The code is below:

int year = 2012 \\or any other year
String monthName = "January" \\or any other month
SimpleDateFormat format = new SimpleDateFormat("dd-MMM-yyyy");
int monthNumber = format.parse("01-" + monthName + "-" + year).getMonth();

Avoid hardcoding try making the code that is dynamic below is the code it will work for any xml I have used SAX Parser you can use dom,xpath it's upto you I am storing all the tags name and values in the map after that it becomes easy to retrieve any values you want I hope this helps
SAMPLE XML:

<parent>
<child >
    <child1> value 1 </child1>
    <child2> value 2 </child2>
    <child3> value 3 </child3>
    </child>
    <child >
     <child4> value 4 </child4>
    <child5> value 5</child5>
    <child6> value 6 </child6>

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

OK, so forget about C. Suppose I give you a number and ask you to determine if it's prime. How do you do it? Write down the steps clearly, then worry about translating them into code.

Once you have the algorithm determined, it will be much easier for you to figure out how to write a program, and for others to help you with it.

edit: Here's the C# code you posted:

static bool IsPrime(int number) {
    for (int i = 2; i < number; i++) {
        if (number % i == 0 && i != number) return false;
    }
    return true;
}

This is very nearly valid C as is; there's no bool type in C, and no true or false, so you need to modify it a little bit (edit: Kristopher Johnson correctly points out that C99 added the stdbool.h header). Since some people don't have access to a C99 environment (but you should use one!), let's make that very minor change:

int IsPrime(int number) {
    int i;
    for (i=2; i<number; i++) {
        if (number % i == 0 && i != number) return 0;
    }
    return 1;
}

This is a perfectly valid C program that does what you want. We can improve it a little bit without too much effort. First, note that i is always less than number, so the check that i != number always succeeds; we can get rid of it.

Also, you don't actually need to try divisors all the way up to number - 1; you can stop checking when you reach sqrt(number). Since sqrt is a floating-point operation and that brings a whole pile of subtleties, we won't actually compute sqrt(number). Instead, we can just check that i*i <= number:

int IsPrime(int number) {
    int i;
    for (i=2; i*i<=number; i++) {
        if (number % i == 0) return 0;
    }
    return 1;
}

One last thing, though; there was a small bug in your original algorithm! If number is negative, or zero, or one, this function will claim that the number is prime. You likely want to handle that properly, and you may want to make number be unsigned, since you're more likely to care about positive values only:

int IsPrime(unsigned int number) {
    if (number <= 1) return 0; // zero and one are not prime
    unsigned int i;
    for (i=2; i*i<=number; i++) {
        if (number % i == 0) return 0;
    }
    return 1;
}

This definitely isn't the fastest way to check if a number is prime, but it works, and it's pretty straightforward. We barely had to modify your code at all!

Add two headers Content-Type and Accept to be equal to application/json.

handleGetJson(){
  console.log("inside handleGetJson");
  fetch(`./fr.json`, {
      headers : { 
        'Content-Type': 'application/json',
        'Accept': 'application/json'
       }

    })
    .then((response) => response.json())
    .then((messages) => {console.log("messages");});
}

Some code to walk through a list of titles (circularily or one-shot):

    var titles = [
            " title",
            "> title",
            ">> title",
            ">>> title"
    ];

    // option 1:
    function titleAniCircular(i) {
            // from first to last title and back again, forever
            i = (!i) ? 0 : (i*1+1) % titles.length;
            $('title').html(titles[i]);
            setTimeout(titleAniCircular, 1000, [i]);
    };

    // option 2:
    function titleAniSequence(i) {
            // from first to last title and stop
            i = (!i) ? 0 : (i*1+1);
            $('title').html(titles[i]);
            if (i<titles.length-1) setTimeout(titleAniSequence, 1000, [i]);
    };

    // then call them when you like.
    // e.g. to call one on document load, uncomment one of the rows below:

    //$(document).load( titleAniCircular() );
    //$(document).load( titleAniSequence() );

Try binaryjs. Its just like socket.io but only thing it do well is that it stream audio video. Binaryjs google it

If you also want to bind closing of infowindow to some event, try something like this

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
        windows.push(infowindow)
        google.maps.event.addListener(map,'click', function(){ 
            infowindow.close();
        }); 
    };
})(marker,content,infowindow)); 

timestamp (or date or time columns) do NOT have "a format".

Any formatting you see is applied by the SQL client you are using.

To insert the current time use current_timestamp as documented in the manual:

INSERT into "Group" (name,createddate) 
VALUES ('Test', current_timestamp);

To display that value in a different format change the configuration of your SQL client or format the value when SELECTing the data:

select name, to_char(createddate, ''yyyymmdd hh:mi:ss tt') as created_date
from "Group"

For psql (the default command line client) you can configure the display format through the configuration parameter DateStyle: https://www.postgresql.org/docs/current/static/runtime-config-client.html#GUC-DATESTYLE

A solution is to add captures for the preceding and following text:

str.replace(/(.*name="\w+)(\d+)(\w+".*)/, "$1!NEW_ID!$3")

I know this is an old question, but I've found another answer that worked better for me and it doesn't seem to appear in any of the answers.

Create a layout xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="5dip"
    android:paddingBottom="5dip"
    android:paddingStart="10dip"
    android:paddingEnd="10dip">

<ImageView
    android:id="@+id/shoe_select_icon"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:layout_gravity="center_vertical"
    android:scaleType="fitXY" />

<TextView
    android:id="@+id/shoe_select_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:textSize="20sp"
    android:paddingStart="10dp"
    android:paddingEnd="10dp"/>

</LinearLayout>

Create a ListPopupWindow and a map with the content:

ListPopupWindow popupWindow;
List<HashMap<String, Object>> data = new ArrayList<>();
HashMap<String, Object> map = new HashMap<>();
    map.put(TITLE, getString(R.string.left));
    map.put(ICON, R.drawable.left);
    data.add(map);
    map = new HashMap<>();
    map.put(TITLE, getString(R.string.right));
    map.put(ICON, R.drawable.right);
    data.add(map);

Then on click, display the menu using this function:

private void showListMenu(final View anchor) {
    popupWindow = new ListPopupWindow(this);

    ListAdapter adapter = new SimpleAdapter(
            this,
            data,
            R.layout.shoe_select,
            new String[] {TITLE, ICON}, // These are just the keys that the data uses (constant strings)
            new int[] {R.id.shoe_select_text, R.id.shoe_select_icon}); // The view ids to map the data to

    popupWindow.setAnchorView(anchor);
    popupWindow.setAdapter(adapter);
    popupWindow.setWidth(400);
    popupWindow.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            switch (position){
                case 0:
                    devicesAdapter.setSelectedLeftPosition(devicesList.getChildAdapterPosition(anchor));

Using the CLI, to create a functioning NUnit project is really easy. The template does everything for you.

dotnet new -i NUnit3.DotNetNew.Template
dotnet new nunit

On .NET Core, this is definitely my preferred way to go.

You can use setText(java.lang.String text, boolean html) from MimeMessageHelper:

MimeMessage mimeMsg = javaMailSender.createMimeMessage();
MimeMessageHelper msgHelper = new MimeMessageHelper(mimeMsg, false, "utf-8");
boolean isHTML = true;
msgHelper.setText("<h1>some html</h1>", isHTML);

But you need to:

mimeMsg.saveChanges();

Before:

javaMailSender.send(mimeMsg);

For DB2, the syntax is:

ALTER TABLE one ADD two_id INTEGER FOREIGN KEY (two_id) REFERENCES two (id);

All I'm really interested in is the ownership and permissions information for the first level subdirectories.

I found a easy solution while playing my fish, which fits your need perfectly.

ls -l $(ls)

Use JSON classes for parsing e.g

JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String  uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");

JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
