SQL Server:

select * from table
except
select top N * from table

Oracle up to 11.2:

select * from table
minus
select * from table where rownum <= N

with TableWithNum as (
    select t.*, rownum as Num
    from Table t
)
select * from TableWithNum where Num > N

Oracle 12.1 and later (following standard ANSI SQL)

select *
from table
order by some_column 
offset x rows
fetch first y rows only

They may meet your needs more or less.

There is no direct way to do what you want by SQL. However, it is not a design flaw, in my opinion.

SQL is not supposed to be used like this.

In relational databases, a table represents a relation, which is a set by definition. A set contains unordered elements.

Also, don't rely on the physical order of the records. The row order is not guaranteed by the RDBMS.

If the ordering of the records is important, you'd better add a column such as `Num' to the table, and use the following query. This is more natural.

select * 
from Table 
where Num > N
order by Num

To understand this let's consider an example where we have a class Mammal which defines readAndGet method which is reading some file, doing some operation on it and returning an instance of class Mammal.

class Mammal {
    public Mammal readAndGet() throws IOException {//read file and return Mammal`s object}
}

Class Human extends class Mammal and overrides readAndGet method to return the instance of Human instead of the instance of Mammal.

class Human extends Mammal {
    @Override
    public Human readAndGet() throws FileNotFoundException {//read file and return Human object}
}

To call readAndGet we will need to handle IOException because its a checked exception and mammal's readAndMethod is throwing it.

Mammal mammal = new Human();
try {
    Mammal obj = mammal.readAndGet();
} catch (IOException ex) {..}

And we know that for compiler mammal.readAndGet() is getting called from the object of class Mammal but at, runtime JVM will resolve mammal.readAndGet() method call to a call from class Human because mammal is holding new Human().

Method readAndMethod from Mammal is throwing IOException and because it is a checked exception compiler will force us to catch it whenever we call readAndGet on mammal

Now suppose readAndGet in Human is throwing any other checked exception e.g. Exception and we know readAndGet will get called from the instance of Human because mammal is holding new Human().

Because for compiler the method is getting called from Mammal, so the compiler will force us to handle only IOException but at runtime we know method will be throwing Exception exception which is not getting handled and our code will break if the method throws the exception.

That's why it is prevented at the compiler level itself and we are not allowed to throw any new or broader checked exception because it will not be handled by JVM at the end.

There are other rules as well which we need to follow while overriding the methods and you can read more on Why We Should Follow Method Overriding Rules to know the reasons.

To open a URL with the default browser, you can execute:

rundll32 url.dll,FileProtocolHandler https://www.google.com

I had issues with URL parameters with the other solutions. However, this one seemed to work correctly.

Without using inline CSS you could set the text size of all your buttons using:

input[type="submit"], input[type="button"] {
  font-size: 14px;
}

In C++, you can use the global function std::getline, it takes a string and a stream and an optional delimiter and reads 1 line until the delimiter specified is reached. An example:

#include <string>
#include <iostream>
#include <fstream>

int main() {
    std::ifstream input("filename.txt");
    std::string line;

    while( std::getline( input, line ) ) {
        std::cout<<line<<'\n';
    }

    return 0;
}

This program reads each line from a file and echos it to the console.

For C you're probably looking at using fgets, it has been a while since I used C, meaning I'm a bit rusty, but I believe you can use this to emulate the functionality of the above C++ program like so:

#include <stdio.h>

int main() {
    char line[1024];
    FILE *fp = fopen("filename.txt","r");

    //Checks if file is empty
    if( fp == NULL ) {                       
        return 1;
    }

    while( fgets(line,1024,fp) ) {
        printf("%s\n",line);
    }

    return 0;
}

With the limitation that the line can not be longer than the maximum length of the buffer that you're reading in to.

Add this to you applicationContext:

 <bean id="userService" class="com.example.my.services.user.UserServiceImpl ">

Using MS SQL Server 2012, you need to perform 3 basic steps:

1. First, generate .sql file containing only the structure of the source DB

   • right click on the source DB and then Tasks then Generate Scripts
   • follow the wizard and save the .sql file locally

2. Second, replace the source DB with the destination one in the .sql file

   • Right click on the destination file, select New Query and Ctrl-H or (Edit - Find and replace - Quick replace)

3. Finally, populate with data

   • Right click on the destination DB, then select Tasks and Import Data
   • Data source drop down set to ".net framework data provider for SQL server" + set the connection string text field under DATA ex: Data Source=Mehdi\SQLEXPRESS;Initial Catalog=db_test;User ID=sa;Password=sqlrpwrd15
   • do the same with the destination
   • check the table you want to transfer or check box besides "source: ..." to check all of them

You are done.

If i understand your question right then,

Yes you can set style of individual element if its id or name is available,

e.g.

if id available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsById('goButton');

v_obj.setAttribute('style','color:red;background:none');

else if name is available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsByName('goButton');

v_obj.setAttribute('style','color:red;background:none');

I think the following is the simplest solution which allows for a given length:

Array(myLength).fill(0).map(x => Math.random().toString(36).charAt(2)).join('')

It depends on the arrow function syntax.

On the same win10 OS system using "two distinct method approaches" there appears to be an approximate "500 ns" time difference. If you care about nanosecond precision check my code below.

The modifications of the code is based on code from user cod3monk3y and Kevin S.

OS: python 3.7.3 (default, date, time) [MSC v.1915 64 bit (AMD64)]

def measure1(mean):

        if i-1 == 0:
            td = 0
        td = f'{td:.6f}'
        samples1.append((i, td, x))
        mean += float(td)
        print (mean)
        sys.stdout.flush()
        time.sleep(0.001)
    
    mean = mean/my_range
    
    return mean

def measure2(nr):
    t0 = time.time()
    t1 = t0
    while t1 == t0:

You have to convert the "DateTime" to a "Date". Then you can easier select just one for the given date no matter the time for that date.

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

One way is to use DispatchQueue.main.asyncAfter as a lot of people have answered.

Another way is to use perform(_:with:afterDelay:). More details here

perform(#selector(delayedFunc), with: nil, afterDelay: 3)

@IBAction func delayedFunc() {
    // implement code
}

I was looking for an easier-to-read time-loop when I encountered this question here. Something like:

for sec in max_seconds(10):
      do_something()

So I created this helper:

# allow easy time-boxing: 'for sec in max_seconds(42): do_something()'
def max_seconds(max_seconds, *, interval=1):
    interval = int(interval)
    start_time = time.time()
    end_time = start_time + max_seconds
    yield 0
    while time.time() < end_time:
        if interval > 0:
            next_time = start_time
            while next_time < time.time():
                next_time += interval
            time.sleep(int(round(next_time - time.time())))
        yield int(round(time.time() - start_time))
        if int(round(time.time() + interval)) > int(round(end_time)): 
            return

It only works with full seconds which was OK for my use-case.

Examples:

for sec in max_seconds(10) # -> 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
for sec in max_seconds(10, interval=3) # -> 0, 3, 6, 9
for sec in max_seconds(7): sleep(1.5) # -> 0, 2, 4, 6
for sec in max_seconds(8): sleep(1.5) # -> 0, 2, 4, 6, 8

Be aware that interval isn't that accurate, as I only wait full seconds (sleep never was any good for me with times < 1 sec). So if your job takes 500 ms and you ask for an interval of 1 sec, you'll get called at: 0, 500ms, 2000ms, 2500ms, 4000ms and so on. One could fix this by measuring time in a loop rather than sleep() ...

In my case, the site was fine in server but not in local. Then I remember I was working on secure website.
So in file config.session.php, set the variable secure to false

'secure' => env('SESSION_SECURE_COOKIE', false),

There is no explicit analogue - i think you are expected to use string concatenations(likely optimized as said before) or third-party class(i doubt that they are a lot more efficient - lists in python are dynamic-typed so no fast-working char[] for buffer as i assume). Stringbuilder-like classes are not premature optimization because of innate feature of strings in many languages(immutability) - that allows many optimizations(for example, referencing same buffer for slices/substrings). Stringbuilder/stringbuffer/stringstream-like classes work a lot faster than concatenating strings(producing many small temporary objects that still need allocations and garbage collection) and even string formatting printf-like tools, not needing of interpreting formatting pattern overhead that is pretty consuming for a lot of format calls.

Just make it fun !

Amazingly Scala might be the easiest if you try Kojo

If you are worrying about Case sensitive change the case and compare the string.

 if (stringvalue.toLocaleLowerCase().indexOf("mytexttocompare")!=-1)
        {

            alert("found");
        }

If you using eclipse, try below: 1. Right click on the project -> select Export 2. Select Runnable Jar file in the select an export destination 3. Enter jar's name and Select "Package required ... " (second radio button) -> Finish

Hope this helps...!

I know it's late answer but I had same problem for last two days, and none of the above solutions worked for me. My app supports min sdk 16, Jelly Bean 4.1.x, so I wanted to test my app on emulator with 16 android api version and I needed Google Play Services.

In short, solution that worked for me is:

• make new emulator Nexus 5X (with Play Store support) - Jelly Bean 4.1.x, 16 API level (WITHOUT Google APIs)
• manually download apks of Google Play Store and Google Play Services (it is necessary that both apks have similar version, they need to start with same number, for example 17.x)
• drag and drop those apks into new emulator
• congratulations you have updated Google Play Services on your 4.1.x emulator

Here are the steps and errors I have encountered during the problem.

So I have made new emulator in my AVD. I picked Nexus 5X (with Play Store support). After that I picked Jelly Bean 16 api level (with Google APIs). When I opened my app dialog pop up with message You need to update your Google play services. When I clicked on Update button, nothing happened. I did update everything necessary in SDK manager, but nothing worked. I didn't have installed Google Play Store on my emulator, even tho I picked Nexus 5X which comes with preinstalled Play Store. So I couldn't find Google Play Store tab in Extended Controls (tree dots next to my emulator).

Because nothings worked, I decided to try to install Google Play Services manually, by downloading APK and dragging it into emulator. When I tried this, I encountered problem The APK failed to install. Error: INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES. I figured that this was the problem because I picked Jelly Bean 16 api level (with Google APIs). So I made new emulator

Nexus 5X (with Play Store support) - Jelly Bean 16 api level (WITHOUT Google APIs)

This allowed me to install my Google Play Service manually. But when I run my app, it still didn't want to open it. Problem was that my emulator was missing Google Play Store. So I installed it manually like Google Play Service. But when it was successfully installed, dialog started popping out every second with message Unfortunately Google Play Services has stopped. Problem was that version of my Google Play Store was 17.x and Google Play Service was 19.x. So at the end I installed Google Play Service with version 17.x, and everything worked.

Extract your file with Tar archiving tool. you can use it in this way:

tar xf example.sql.gz

Hidden iframes can help

You can use sed for this. For example:

$ sed -n '/Feb 23 13:55/,/Feb 23 14:00/p' /var/log/mail.log
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: connect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: lost connection after CONNECT from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: disconnect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie pop3d: Connection, ip=[::ffff:127.0.0.1]
...

How it works

The -n switch tells sed to not output each line of the file it reads (default behaviour).

The last p after the regular expressions tells it to print lines that match the preceding expression.

The expression '/pattern1/,/pattern2/' will print everything that is between first pattern and second pattern. In this case it will print every line it finds between the string Feb 23 13:55 and the string Feb 23 14:00.

export default affects the syntax when importing the exported "thing", when allowing to import, whatever has been exported, by choosing the name in the import itself, no matter what was the name when it was exported, simply because it's marked as the "default".

A useful use case, which I like (and use), is allowing to export an anonymous function without explicitly having to name it, and only when that function is imported, it must be given a name:

Example:

Export 2 functions, one is default:

export function divide( x ){
    return x / 2;
}

// only one 'default' function may be exported and the rest (above) must be named
export default function( x ){  // <---- declared as a default function
    return x * x;
}

Import the above functions. Making up a name for the default one:

// The default function should be the first to import (and named whatever)
import square, {divide} from './module_1.js'; // I named the default "square" 

console.log( square(2), divide(2) ); // 4, 1

When the {} syntax is used to import a function (or variable) it means that whatever is imported was already named when exported, so one must import it by the exact same name, or else the import wouldn't work.

Erroneous Examples:

1. The default function must be first to import

   import {divide}, square from './module_1.js
   

2. divide_1 was not exported in module_1.js, thus nothing will be imported

   import {divide_1} from './module_1.js
   

3. square was not exported in module_1.js, because {} tells the engine to explicitly search for named exports only.

   import {square} from './module_1.js
   

From the jquery docs for POST (3rd example):

$.post("test.php", { 'choices[]': ["Jon", "Susan"] });

So I would just iterate over the checked boxes and build the array. Something like

var data = { 'user_ids[]' : []};
$(":checked").each(function() {
  data['user_ids[]'].push($(this).val());
});
$.post("ajax.php", data);

Alternatively you could use a for loop as shown in the Groovy Docs:

def map = ['a':1, 'b':2, 'c':3]
for ( e in map ) {
    print "key = ${e.key}, value = ${e.value}"
}

/*
Result:
key = a, value = 1
key = b, value = 2
key = c, value = 3
*/

One benefit of using a for loop as opposed to an each closure is easier debugging, as you cannot hit a break point inside an each closure (when using Netbeans).

The answers provided above solve the problem but don't explain the strange behaviour the OP described. This explanation should help anyone testing communication between sites in a development environment where these sites all reside on the same host (and the same virtualhost; I'm working with apache 2.4 and php7.0).

There's a subtlety with file_get_contents() I came across that is absolutely relevant here but unaddressed (probably because it's either barely documented or not documented from what I can tell or is documented in an obscure php security model whitepaper I can't find).

With allow_url_fopen set to Off in all relevant contexts (e.g. /etc/php/7.0/apache2/php.ini, /etc/php/7.0/fpm/php.ini, etc...) and allow_url_fopen set to On in the command line context (i.e. /etc/php/7.0/cli/php.ini), calls to file_get_contents() for a local resource will be allowed and no warning will be logged such as:

file_get_contents('php://input');

or

// Path outside document root that webserver user agent has permission to read. e.g. for an apache2 webserver this user agent might be www-data so a file at /etc/php/7.0/filetoaccess would be successfully read if www-data had permission to read this file
file_get_contents('<file path to file on local machine user agent can access>');

or

// Relative path in same document root
file_get_contents('data/filename.dat')

To conclude, the restriction allow_url_fopen = Off is analogous to an iptables rule in the OUTPUT chain, where the restriction is only applied when an attempt to "exit the system" or "change contexts" is made.

N.B. allow_url_fopen set to On in the command line context (i.e. /etc/php/7.0/cli/php.ini) is what I had on my system but I suspect it would have no bearing on the explanation I provided even if it were set to Off unless of course you're testing by running your scripts from the command line itself. I did not test the behaviour with allow_url_fopen set to Off in the command line context.

Sometimes it can be dangerous to convert charsets, specially on databases with huge amounts of data. I think the best option is to use the "binary" operator:

e.g : WHERE binary table1.column1 = binary table2.column1

There is a way to catch the error directly in the except clause with ConnectionResetError, better to isolate the right error. This example also catches the timeout.

from urllib.request import urlopen 
from socket import timeout

url = "http://......"
try: 
    string = urlopen(url, timeout=5).read()
except ConnectionResetError:
    print("==> ConnectionResetError")
    pass
except timeout: 
    print("==> Timeout")
    pass

Fetch promises only reject with a TypeError when a network error occurs. Since 4xx and 5xx responses aren't network errors, there's nothing to catch. You'll need to throw an error yourself to use Promise#catch.

A fetch Response conveniently supplies an ok , which tells you whether the request succeeded. Something like this should do the trick:

fetch(url).then((response) => {
  if (response.ok) {
    return response.json();
  } else {
    throw new Error('Something went wrong');
  }
})
.then((responseJson) => {
  // Do something with the response
})
.catch((error) => {
  console.log(error)
});

There is no way to distinct string and base64 encoded, except the string in your system has some specific limitation or identification.

Your instance name might differ. Either way pop over to VS and open Server Explorer, right click Data Connections, choose Add, choose SQL Server, in the server name type:

(localdb)\MSSQLLocalDB

Without entering in a DB name, click 'Test Connection'.

There are multiple methods for handling this problem.

My advice is to use the powerful Windows freeware console application SendEmail.

sendEmail.exe -f [email protected] -o message-file=body.txt -u subject message -t [email protected] -a attachment.zip -s smtp.gmail.com:446 -xu gmail.login -xp gmail.password

The below query helps to get the row number in oracle,

SELECT ROWNUM AS SNO,ID,NAME,EMAIL,BRANCH FROM student WHERE NAME LIKE '%ram%';

Do this:

 $( '#wrapper' ).on( 'click', 'a', function () { ... });

where #wrapper is a static element in which you add the dynamic links.

So, you have a wrapper which is hard-coded into the HTML source code:

<div id="wrapper"></div>

and you fill it with dynamic content. The idea is to delegate the events to that wrapper, instead of binding handlers directly on the dynamic elements.

Btw, I recommend Backbone.js - it gives structure to this process:

var YourThing = Backbone.View.extend({

    // the static wrapper (the root for event delegation)
    el: $( '#wrapper' ),

    // event bindings are defined here 
    events: {
        'click a': 'anchorClicked'
    },

    // your DOM event handlers
    anchorClicked: function () {
        // handle click event 
    }

});

new YourThing; // initializing your thing

My setup has got two cases for this error:

• __pycache__ files created by root user after I run integration tests inside container are inaccessible for docker (tells you original problem) and docker-compose (tells you about docker host ambiguously);
• microk8s blocked my port until I stopped it.

Taken from a related post:

public static boolean isInteger(String s) {
    try { 
        Integer.parseInt(s); 
    } catch(NumberFormatException e) { 
        return false; 
    }
    // only got here if we didn't return false
    return true;
}

For Windows:

• Ctrl+K,Ctrl+U for UPPERCASE.
• Ctrl+K,Ctrl+L for lowercase.

Method 1 (Two keys pressed at a time)

1. Press Ctrl and hold.
2. Now press K, release K while holding Ctrl. (Do not release the Ctrl key)
3. Immediately, press U (for uppercase) OR L (for lowercase) with Ctrl still being pressed, then release all pressed keys.

Method 2 (3 keys pressed at a time)

1. Press Ctrl and hold.
2. Now press K.
3. Without releasing Ctrl and K, immediately press U (for uppercase) OR L (for lowercase) and release all pressed keys.

Please note: If you press and hold Ctrl+K for more than two seconds it will start deleting text so try to be quick with it.

I use the above shortcuts, and they work on my Windows system.

Have you tried using connection.execute(text( <sql here> ), <bind params here> ) and bind parameters as described in the docs? This can help solve many parameter formatting and performance problems. Maybe the gateway error is a timeout? Bind parameters tend to make complex queries execute substantially faster.

Spark 2.2+

Spark 2.2 introduces typedLit to support Seq, Map, and Tuples (SPARK-19254) and following calls should be supported (Scala):

import org.apache.spark.sql.functions.typedLit

df.withColumn("some_array", typedLit(Seq(1, 2, 3)))
df.withColumn("some_struct", typedLit(("foo", 1, 0.3)))
df.withColumn("some_map", typedLit(Map("key1" -> 1, "key2" -> 2)))

Spark 1.3+ (lit), 1.4+ (array, struct), 2.0+ (map):

The second argument for DataFrame.withColumn should be a Column so you have to use a literal:

from pyspark.sql.functions import lit

df.withColumn('new_column', lit(10))

If you need complex columns you can build these using blocks like array:

from pyspark.sql.functions import array, create_map, struct

df.withColumn("some_array", array(lit(1), lit(2), lit(3)))
df.withColumn("some_struct", struct(lit("foo"), lit(1), lit(.3)))
df.withColumn("some_map", create_map(lit("key1"), lit(1), lit("key2"), lit(2)))

Exactly the same methods can be used in Scala.

import org.apache.spark.sql.functions.{array, lit, map, struct}

df.withColumn("new_column", lit(10))
df.withColumn("map", map(lit("key1"), lit(1), lit("key2"), lit(2)))

To provide names for structs use either alias on each field:

df.withColumn(
    "some_struct",
    struct(lit("foo").alias("x"), lit(1).alias("y"), lit(0.3).alias("z"))
 )

or cast on the whole object

df.withColumn(
    "some_struct", 
    struct(lit("foo"), lit(1), lit(0.3)).cast("struct<x: string, y: integer, z: double>")
 )

It is also possible, although slower, to use an UDF.

Note:

The same constructs can be used to pass constant arguments to UDFs or SQL functions.

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

1. First make sure sa is enabled
2. Change the authontication mode to mixed mode (Window and SQL authentication)
3. Stop your SQL Server
4. Restart your SQL Server

Easy one ;)

SELECT * FROM `WAYPOINTS` W ORDER BY
ABS(ABS(W.`LATITUDE`-53.63) +
ABS(W.`LONGITUDE`-9.9)) ASC LIMIT 30;

Just replace the coordinates with your required ones. The values have to be stored as double. This ist a working MySQL 5.x example.

Here is an answer to your question that goes into detail: http://www.velocityreviews.com/forums/t372598-maximum-size-of-byte-array.html

You may want to mention which version of .NET you are using and your memory size.

You will be stuck to a 2G, for your application, limit though, so it depends on what is in your array.

As an extension method:

//     Returns a copy of this string converted to `Title Case`.
/// </summary>
/// <param name="value">The string to convert.</param>
/// <returns>The `Title Case` equivalent of the current string.</returns>
public static string ToTitleCase(this string value)
{
    string result = string.Empty;

    for (int i = 0; i < value.Length; i++)
    {
        char p = i == 0 ? char.MinValue : value[i - 1];
        char c = value[i];

        result += char.IsLetter(c) && ((p is ' ') || p is char.MinValue) ? $"{char.ToUpper(c)}" : $"{char.ToLower(c)}";

    return result;

Add XAttribute in the constructor of the XElement, like

new XElement("Conn", new XAttribute("Server", comboBox1.Text));

You can also add multiple attributes or elements via the constructor

new XElement("Conn", new XAttribute("Server", comboBox1.Text), new XAttribute("Database", combobox2.Text));

or you can use the Add-Method of the XElement to add attributes

XElement element = new XElement("Conn");
XAttribute attribute = new XAttribute("Server", comboBox1.Text);
element.Add(attribute);

From the use of 8080 I'm assuming you are using a tomcat servlet container to serve your rest api. If this is the case you can also consider to have your webserver proxy the requests to the servlet container.

With apache you would typically use mod_jk (although there are other alternatives) to serve the api trough the web server behind port 80 instead of 8080 which would solve the cross domain issue.

This is common practice, have the 'static' content in the webserver and dynamic content in the container, but both served from behind the same domain.

The url for the rest api would be http://localhost/restws/json/product/get

Here a description on how to use mod_jk to connect apache to tomcat: http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html

Rsync daemon by default uses nobody/nogroup for all modules if it is running under root user. So you either need to define params uid and gid to the user you want, or set them to root/root.

In the course of developing an in-house address verification service at a German company I used to work for I've come across a number of ways to tackle this issue. I'll do my best to sum up my findings below:

Free, Open Source Software

Clearly, the first approach anyone would take is an open-source one (like openstreetmap.org), which is never a bad idea. But whether or not you can really put this to good and reliable use depends very much on how much you need to rely on the results.

Addresses are an incredibly variable thing. Verifying U.S. addresses is not an easy task, but bearable, but once you're going for Europe, especially the U.K. with their extensive Postal Code system, the open-source approach will simply lack data.

Web Services / APIs

Enterprise-Class Software

Money gets it done, obviously. But not every business or developer can spend ~$0.15 per address lookup (that's $150 for 1,000 API requests) - a very expensive business model the vast majority of address validation APIs have implemented.

What I ended up integrating: streetlayer API

Since I was not willing to take on the programmatic approach of verifying address data manually I finally came to the conclusion that I was in need of an API with a price tag that would not make my boss want to fire me and still deliver solid and reliable international verification results.

Long story short, I ended up integrating an API built by apilayer, called "streetlayer API". I was easily convinced by a simple JSON integration, surprisingly accurate validation results and their developer-friendly pricing. Also, 100 requests/month are entirely free.

Hope this helps!

.catch(error => { throw error}) is a no-op. It results in unhandled rejection in route handler.

As explained in this answer, Express doesn't support promises, all rejections should be handled manually:

router.get("/emailfetch", authCheck, async (req, res, next) => {
  try {
  //listing messages in users mailbox 
    let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
    emailFetch = emailFetch.data
    res.send(emailFetch)
  } catch (err) {
    next(err);
  }
})

Try this :

select replace (colname, char(39)+char(39), '') AS colname FROM .[dbo].[Db Name];

I have achieved the desired result. Example : Input value --> Like '%Pat') '' OR

      Want Output -->  *Like '%Pat') OR*

using above query achieved the desired result.

The thing about collations is that although the database has its own collation, every table, and every column can have its own collation. If not specified it takes the default of its parent object, but can be different.

When you change collation of the database, it will be the new default for all new tables and columns, but it doesn't change the collation of existing objects inside the database. You have to go and change manually the collation of every table and column.

Luckily there are scripts available on the internet that can do the job. I am not going to recommend any as I haven't tried them but here are few links:

http://www.codeproject.com/Articles/302405/The-Easy-way-of-changing-Collation-of-all-Database

Update Collation of all fields in database on the fly

http://www.sqlservercentral.com/Forums/Topic820675-146-1.aspx

If you need to have different collation on two objects or can't change collations - you can still JOIN between them using COLLATE command, and choosing the collation you want for join.

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE Latin1_General_CI_AS 

or using default database collation:

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE DATABASE_DEFAULT

I had this problem because I had a typo in my template near [(ngModel)]]. Extra bracket. Example:

<input id="descr" name="descr" type="text" required class="form-control width-half"
      [ngClass]="{'is-invalid': descr.dirty && !descr.valid}" maxlength="16" [(ngModel)]]="category.descr"
      [disabled]="isDescrReadOnly" #descr="ngModel">

This might be helpful to somebody. here is the snippet from httpd.conf (Apache version 2.2 windows)

# DirectoryIndex: sets the file that Apache will serve if a directory
# is requested.
#
<IfModule dir_module>
    DirectoryIndex index.html
    DirectoryIndex index.php
</IfModule>

now this will look for index.html file if not found it will look for index.php.

An <iframe> gives you a complete window to work with. The most direct way to do what you want is to have your server give you a complete page that only contains the fragment you want to show.

As an alternative, you could just use a simple <div> and use the jQuery "load" function to load the whole page and pluck out just the section you want:

$('#target-div').load('http://www.mywebsite.com/portfolio.php #portfolio-sports');

There may be other things you need to do, and a significant difference is that the content will become part of the main page instead of being segregated into a separate window.

All of the above might be true, however for me "online-updating" of figures only works with some backends, specifically wx. You just might try to change to this, e.g. by starting ipython/pylab by ipython --pylab=wx! Good luck!

if needed, changing the beginning clause of this regex to be /([^>[\s]?\r\n]?) will also ingore the cases where the newline comes after a tag AND some whitespace, instead of just a tag immediately followed by a newline

• .NET Core will install and run on macOS - and just about any other desktop OS.
  IDEs are available for the mac, including:

  • Visual Studio for Mac
  • VS Code (free, but not as professional/focused as VS)
  • JetBrains Rider (paid)

• Mono is a good option that I've used in the past. But with Core 3.0 out now, I would go that route.

Live Demo

The issue is in the line -

grade_1, grade_2, grade_3, average = 0.0

and

fName, lName, ID, converted_ID = ""

In python, if the left hand side of the assignment operator has multiple variables, python would try to iterate the right hand side that many times and assign each iterated value to each variable sequentially. The variables grade_1, grade_2, grade_3, average need three 0.0 values to assign to each variable.

You may need something like -

grade_1, grade_2, grade_3, average = [0.0 for _ in range(4)]
fName, lName, ID, converted_ID = ["" for _ in range(4)]

If you use Java >= 7, you could improve the accepted solution using try with resources:

private byte[] convertToBytes(Object object) throws IOException {
    try (ByteArrayOutputStream bos = new ByteArrayOutputStream();
         ObjectOutputStream out = new ObjectOutputStream(bos)) {
        out.writeObject(object);
        return bos.toByteArray();
    } 
}

And the other way around:

private Object convertFromBytes(byte[] bytes) throws IOException, ClassNotFoundException {
    try (ByteArrayInputStream bis = new ByteArrayInputStream(bytes);
         ObjectInputStream in = new ObjectInputStream(bis)) {
        return in.readObject();
    } 
}

for counting:

$('.yourClass').length;

should work fine.

storing in a variable is as easy as:

var count = $('.yourClass').length;

Here is a single line that will create (or overwrite) the file:

File.Create("C:\my files\2010\SomeFileName.txt").Dispose()

Note: calling Dispose() ensures that the reference to the file is closed.

If you found this thread trying to compare data fames in tests, then take a look at assert_frame_equal method: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.testing.assert_frame_equal.html

is there a problem with:

Rectangle box1 = new Rectangle(100,100,100,100);
Rectangle box2 = new Rectangle(200,200,100,100);

// what this means is if any pixel in box2 enters (hits) box1
if (box1.contains(box2)) 
{
     // collision occurred
}

// your code for moving the boxes 

this can also be applied to circles:

Ellipse2D.Double ball1 = new Ellipse2D.Double(100,100,200,200);
Ellipse2D.Double ball2 = new Ellipse2D.Double(400,100,200,200);

// what this means is if any pixel on the circumference in ball2 touches (hits)
// ball1
    if (ball1.contains(ball2)) 
    {
         // collision occurred
    }

    // your code for moving the balls

to check whether youve hit the edge of a screen you could use the following:

Rectangle screenBounds = jpanel.getBounds();
Ellipse2D.Double ball = new Ellipse2D.Double(100,100,200,200);  // diameter 200
Rectangle ballBounds = ball.getBounds();

if (!screenBounds.contains(ballBounds))
{
// the ball touched the edge of the screen
}

A standard width space for a standard 16px font is 4px.

Source: http://jkorpela.fi/styles/spaces.html

I don't think that you need to use each(), you can use standard for loop

var children = $element.children().not(".pb-sortable-placeholder");
for (var i = 0; i < children.length; i++) {
    var currentChild = children.eq(i);
    // whatever logic you want
    var oldPosition = currentChild.data("position");
}

this way you can have the standard for loop features like break and continue works by default

also, the debugging will be easier

Just if anyone is looking how to hide modal when clicking outside the modal. Since modal usually has its wrapper with class of modal-wrap or anything you named it, you can put @click="closeModal" on the wrapper. Using event handling stated in vuejs documentation, you can check if the clicked target is either on the wrapper or on the modal.

methods: {_x000D_
  closeModal(e) {_x000D_
    this.event = function(event) {_x000D_
      if (event.target.className == 'modal-wrap') {_x000D_
        // close modal here_x000D_
        this.$store.commit("catalog/hideModal");_x000D_
        document.body.removeEventListener("click", this.event);_x000D_
      }_x000D_
    }.bind(this);_x000D_
    document.body.addEventListener("click", this.event);_x000D_
  },_x000D_
}

<div class="modal-wrap" @click="closeModal">_x000D_
  <div class="modal">_x000D_
    ..._x000D_
  </div>_x000D_
<div>

Please add try catch also in your code so that you can be sure that there in no exception.

try {
    $hostname = "servername";
    $dbname = "dbname";
    $username = "username";
    $pw = "password";
    $pdo = new PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw");
  } catch (PDOException $e) {
    echo "Failed to get DB handle: " . $e->getMessage() . "\n";
    exit;
  }

The very easiest way to do this as of today is use pnpm rather than npm and simply type:

pnpm update --latest

Maybe you need to change semi-colon by coma...

when I create my JLabel and enter the text to it, there is no wordwrap or anything

HTML formatting can be used to cause word wrap in any Swing component that offers styled text. E.G. as demonstrated in this answer.

Using parenthesis in a programming language or a scripting language usually means that it is a function.

However $_COOKIE in php is not a function, it is an Array. To access data in arrays you use square braces ('[' and ']') which symbolize which index to get the data from. So by doing $_COOKIE['test'] you are basically saying: "Give me the data from the index 'test'.

Now, in your case, you have two possibilities: (1) either you want to see if it is false--by looking inside the cookie or (2) see if it is not even there.

For this, you use the isset function which basically checks if the variable is set or not.

Example

if ( isset($_COOKIE['test'] ) )

And if you want to check if the value is false and it is set you can do the following:

if ( isset($_COOKIE['test']) && $_COOKIE['test'] == "false" )

One thing that you can keep in mind is that if the first test fails, it wont even bother checking the next statement if it is AND ( && ).

And to explain why you actually get the error "Function must be a string", look at this page. It's about basic creation of functions in PHP, what you must remember is that a function in PHP can only contain certain types of characters, where $ is not one of these. Since in PHP $ represents a variable.

A function could look like this: _myFunction _myFunction123 myFunction and in many other patterns as well, but mixing it with characters like $ and % will not work.

CSS Styles are key-value pairs, not just "tags". By default, each element has a full set of CSS styles assigned to it, most of them is implicitly using the browser defaults and some of them is explicitly redefined in CSS stylesheets.

To get the value assigned to a particular CSS entry of an element and compare it:

if ($('#yourElement').css('position') == 'absolute')
{
   // true
}

If you didn't redefine the style, you will get the browser default for that particular element.

There is indeed a Groovier Way.

if(members){
    //Some work
}

does everything if members is a collection. Null check as well as empty check (Empty collections are coerced to false). Hail Groovy Truth. :)

You can just ask for cancellation but not really terminate it. See this answer.

The GNU guys REALLY messed up when they introduced recursive file searching to grep. grep is for finding REs in files and printing the matching line (g/re/p remember?) NOT for finding files. There's a perfectly good tool with a very obvious name for FINDing files. Whatever happened to the UNIX mantra of do one thing and do it well?

Anyway, here's how you'd do what you want using the traditional UNIX approach (untested):

find /path/to/folder -type f -print |
while IFS= read -r file
do
   awk -v old="$oldstring" -v new="$newstring" '
      BEGIN{ rlength = length(old) }
      rstart = index($0,old) { $0 = substr($0,rstart-1) new substr($0,rstart+rlength) }
      { print }
   ' "$file" > tmp &&
   mv tmp "$file"
done

Not that by using awk/index() instead of sed and grep you avoid the need to escape all of the RE metacharacters that might appear in either your old or your new string plus figure out a character to use as your sed delimiter that can't appear in your old or new strings, and that you don't need to run grep since the replacement will only occur for files that do contain the string you want. Having said all of that, if you don't want the file timestamp to change if you don't modify the file, then just do a diff on tmp and the original file before doing the mv or throw in an fgrep -q before the awk.

Caveat: The above won't work for file names that contain newlines. If you have those then let us know and we can show you how to handle them.

Isn't this code above wrong?

The close call directly after the shutdown call might make the kernel discard all outgoing buffers anyway.

I tried this in my Angular project and it worked fine without jQuery.

<input type='text' ng-paste='preventPaste($event)'>

And in script part:

};

In non angular project, use 'onPaste' instead of 'ng-paste' and 'event' instesd of '$event'.

cout << fixed << setprecision(2) << total;

setprecision specifies the minimum precision. So

cout << setprecision (2) << 1.2; 

will print 1.2

fixed says that there will be a fixed number of decimal digits after the decimal point

cout << setprecision (2) << fixed << 1.2;

will print 1.20

You could also use ?is.element:

dt[is.element(dt$fct, vc),]

HTTP 304 is "not modified". Your web server is basically telling the browser "this file hasn't changed since the last time you requested it." Whereas an HTTP 200 is telling the browser "here is a successful response" - which should be returned when it's either the first time your browser is accessing the file or the first time a modified copy is being accessed.

For more info on status codes check out http://en.wikipedia.org/wiki/List_of_HTTP_status_codes.

You want to pass in the optional second parameter to index, the location where you want index to start looking. After you find each match, reset this parameter to the location just after the match that was found.

def list_duplicates_of(seq,item):
    start_at = -1
    locs = []
    while True:
        try:
            loc = seq.index(item,start_at+1)
        except ValueError:
            break
        else:
            locs.append(loc)
            start_at = loc
    return locs

source = "ABABDBAAEDSBQEWBAFLSAFB"
print(list_duplicates_of(source, 'B'))

Prints:

[1, 3, 5, 11, 15, 22]

You can find all the duplicates at once in a single pass through source, by using a defaultdict to keep a list of all seen locations for any item, and returning those items that were seen more than once.

from collections import defaultdict

def list_duplicates(seq):
    tally = defaultdict(list)
    for i,item in enumerate(seq):
        tally[item].append(i)
    return ((key,locs) for key,locs in tally.items() 
                            if len(locs)>1)

for dup in sorted(list_duplicates(source)):
    print(dup)

Prints:

('A', [0, 2, 6, 7, 16, 20])
('B', [1, 3, 5, 11, 15, 22])
('D', [4, 9])
('E', [8, 13])
('F', [17, 21])
('S', [10, 19])

If you want to do repeated testing for various keys against the same source, you can use functools.partial to create a new function variable, using a "partially complete" argument list, that is, specifying the seq, but omitting the item to search for:

from functools import partial
dups_in_source = partial(list_duplicates_of, source)

for c in "ABDEFS":
    print(c, dups_in_source(c))

Prints:

A [0, 2, 6, 7, 16, 20]
B [1, 3, 5, 11, 15, 22]
D [4, 9]
E [8, 13]
F [17, 21]
S [10, 19]

Beware float: left…

…there are many ways to align elements side-by-side.

Below are the most common ways to achieve two elements side-by-side…

Demo: View/edit all the below examples on Codepen

Basic styles for all examples below…

Some basic css styles for parent and child elements in these examples:

.parent {
  background: mediumpurple;
  padding: 1rem;
}
.child {
  border: 1px solid indigo;
  padding: 1rem;
}

Using the float solution my have unintended affect on other elements. (Hint: You may need to use a clearfix.)

html

<div class='parent'>
  <div class='child float-left-child'>A</div>
  <div class='child float-left-child'>B</div>
</div>

css

.float-left-child {
  float: left;
}

html

<div class='parent'>
  <div class='child inline-block-child'>A</div>
  <div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

Note: the space between these two child elements can be removed, by removing the space between the div tags:

html

<div class='parent'>
  <div class='child inline-block-child'>A</div><div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

html

<div class='parent flex-parent'>
  <div class='child flex-child'>A</div>
  <div class='child flex-child'>B</div>
</div>

css

.flex-parent {
  display: flex;
}
.flex-child {
  flex: 1;
}

html

<div class='parent inline-flex-parent'>
  <div class='child'>A</div>
  <div class='child'>B</div>
</div>

css

.inline-flex-parent {
  display: inline-flex;
}

html

<div class='parent grid-parent'>
  <div class='child'>A</div>
  <div class='child'>B</div>
</div>

css

.grid-parent {
  display: grid;
  grid-template-columns: 1fr 1fr
}

Change/Add to data-interval="false" on carousel div

<div class="carousel slide" data-ride="carousel" data-type="multi" data-interval="false" id="myCarousel">

Add this before calling dialog

$( obiect ).css('zIndex',9999);

And remove

 zIndex: 700,

from dialog

You can find it like

SELECT DISTINCT OBJECT_NAME(id) FROM syscomments WHERE [text] LIKE '%User%'

It will list distinct stored procedure names that contain text like 'User' inside stored procedure. More info

Yup! That's very straight forward and that's where the package strategy comes into play. there are three ways to my knowledge. folder structure:

GOPATH/src/ github.com/ abc/ myproject/ adapter/ main.go pkg1 pkg2 warning: adapter can contain package main only and sun directories

1. navigate to "adapter" folder. Run:

    go build main.go

2. navigate to "adapter" folder. Run:

    go build main.go

3. navigate to GOPATH/src recognize relative path to package main, here "myproject/adapter". Run:

    go build myproject/adapter

exe file will be created at the directory you are currently at.

Keep it simple. No libraries required.

import subprocess

subprocess.Popen("ssh {user}@{host} {cmd}".format(user=user, host=host, cmd='ls -l'), shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()

The heap is the place in memory where your dynamically allocated objects live. If you used new then it's on the heap. That's as opposed to stack space, which is where the function stack lives. If you have a local variable then that reference is on the stack. Java's heap is subject to garbage collection and the objects are usable directly.

EHCache's off-heap storage takes your regular object off the heap, serializes it, and stores it as bytes in a chunk of memory that EHCache manages. It's like storing it to disk but it's still in RAM. The objects are not directly usable in this state, they have to be deserialized first. Also not subject to garbage collection.

Looks like maven is not present in your PATH. Add the absolute maven home\bin location to your PATH.

From the MongoDB cookbook page comments:

"dt" : 
{
    "$gte" : ISODate("2014-07-02T00:00:00Z"), 
    "$lt" : ISODate("2014-07-03T00:00:00Z") 
}

This worked for me. In full context, the following command gets every record where the dt date field has a date on 2013-10-01 (YYYY-MM-DD) Zulu:

db.mycollection.find({ "dt" : { "$gte" : ISODate("2013-10-01T00:00:00Z"), "$lt" : ISODate("2013-10-02T00:00:00Z") }})

I suspect you haven't authorize your Excel installation to run macro from an automated Excel. It is a security protection by default at installation. To change this:

1. File > Options > Trust Center
2. Click on Trust Center Settings... button
3. Macro Settings > Check Enable all macros

try

 String s = "SALES:0,SALE_PRODUCTS:1,EXPENSES:2,EXPENSES_ITEMS:3";
    HashMap<String,Integer> hm =new HashMap<String,Integer>();
    for(String s1:s.split(",")){
       String[] s2 = s1.split(":");
        hm.put(s2[0], Integer.parseInt(s2[1]));
    }

Your Print method likely needs to wait for the continuation to finish (ContinueWith returns a task which you can wait on). Otherwise the second ReadAsStringAsync finishes, the method returns (before result is assigned in the continuation). Same problem exists in your send method. Both need to wait on the continuation to consistently get the results you want. Similar to below

private static string Send(int id)
{
    Task<HttpResponseMessage> responseTask = client.GetAsync("aaaaa");
    string result = string.Empty;
    Task continuation = responseTask.ContinueWith(x => result = Print(x));
    continuation.Wait();
    return result;
}

private static string Print(Task<HttpResponseMessage> httpTask)
{
    Task<string> task = httpTask.Result.Content.ReadAsStringAsync();
    string result = string.Empty;
    Task continuation = task.ContinueWith(t =>
    {
        Console.WriteLine("Result: " + t.Result);
        result = t.Result;
    });
    continuation.Wait();  
    return result;
}

this bellow code gave me correct response

jar cvf MyJar.jar *.properties lib/*.jar -C bin .  

it added the (log4j) properties file, it added the jar files in lib. and then it went inside bin to retrieve the class files with package.

You can use String.Join. If you have a List<string> then you can call ToArray first:

List<string> names = new List<string>() { "John", "Anna", "Monica" };
var result = String.Join(", ", names.ToArray());

In .NET 4 you don't need the ToArray anymore, since there is an overload of String.Join that takes an IEnumerable<string>.

Results:

John, Anna, Monica

A great place to start learning about Subversion is http://svnbook.red-bean.com/.

As far as Visual Studio tools are concerned, I like AnkhSVN, but I haven't tried the VisualSVN plugin yet.

VisualSVN does rely on TortoiseSVN, but TortoiseSVN is also a nice complement to Ankh IMHO.

public Boolean IsPalindrome(string value)
{
   var one = value.ToList<char>();
   var two = one.Reverse<char>().ToList();
   return one.Equals(two);
}

In my case, the problem was styling header as "Header 1" but that style was not exist in the Word that I get the error because it was not an Office in English Language.

If you aren't worried about squeaking every single last bit of performance the suggestion to use a HashSet or binary search is solid. Your datasets just aren't large enough that this is going to be a problem 99% of the time.

But if this just one of thousands of times you are going to do this and performance is critical (and proven to be unacceptable using HashSet/binary search), you could certainly write your own algorithm that walked the sorted lists doing comparisons as you went. Each list would be walked at most once and in the pathological cases wouldn't be bad (once you went this route you'd probably find that the comparison, assuming it's a string or other non-integral value, would be the real expense and that optimizing that would be the next step).

When both values are zero, then the change is zero.

If one of the values is zero, it's infinite (ambiguous), but I would set it to 100%.

Here is a C++ code (where v1 is the previous value (old), and v2 is new):

double result = 0;
if (v1 != 0 && v2 != 0) {
  // If values are non-zero, use the standard formula.
  result = (v2 / v1) - 1;
} else if (v1 == 0 || v2 == 0) {
  // Change is zero when both values are zeros, otherwise it's 100%.
  result = v1 == 0 && v2 == 0 ? 0 : 1;
}
result = v2 > v1 ? abs(result) : -abs(result);
// Note: To have format in hundreds, multiply the result by 100.

You can use an instance of the StringFormat object passed into the DrawString method to center the text.

See Graphics.DrawString Method and StringFormat Class.

If kill -9 isn't working, then neither will killall (or even killall -9 which would be more "intense"). Apparently the chromium process is stuck in a non-interruptible system call (i.e., in the kernel, not in userland) -- didn't think MacOSX had any of those left, but I guess there's always one more:-(. If that process has a controlling terminal you can probably background it and kill it while backgrounded; otherwise (or if the intense killing doesn't work even once the process is bakcgrounded) I'm out of ideas and I'm thinking you might have to reboot:-(.

I have reproduced the issue in my system,

postgres=# alter user my-sys with password 'pass11';
ERROR:  syntax error at or near "-"
LINE 1: alter user my-sys with password 'pass11';
                       ^

Here is the issue,

psql is asking for input and you have given again the alter query see postgres-#That's why it's giving error at alter

postgres-# alter user "my-sys" with password 'pass11';
ERROR:  syntax error at or near "alter"
LINE 2: alter user "my-sys" with password 'pass11';
        ^

Solution is as simple as the error,

postgres=# alter user "my-sys" with password 'pass11';
ALTER ROLE

If you bind your service, you will get the Extra in onBind(Intent intent).

Activity:

 Intent intent = new Intent(this, LocationService.class);                                                                                     
 intent.putExtra("tour_name", mTourName);                    
 bindService(intent, mServiceConnection, BIND_AUTO_CREATE); 

Service:

@Override
public IBinder onBind(Intent intent) {
    mTourName = intent.getStringExtra("tour_name");
    return mBinder;
}

Found a workaround years later after encountering the same problem again - unable to click element even though it SHOULD be clickable. The solution is to catch ElementNotInteractable exception and attempt to execute a script to click the element.

Example in Typescript

async clickElement(element: WebElement) {
    try {
        return await element.click();
    } catch (error) {
        if (error.name == 'ElementNotInteractableError') {
            return await this.driver.executeScript((element: WebElement) => {
                element.click();
            }, element);
        }
    }
}

FYI, in newer versions of Windows, there's a new setting where if a program is running in Adminstrator mode, then another program not in administrator mode, cannot send any clicks or other input events to it. Check your source program to which you are trying to send the click (right click -> properties), and see if the 'run as administrator' checkbox is selected.

create shake.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromXDelta="0" 
        android:toXDelta="10" 
            android:duration="1000" 
                android:interpolator="@anim/cycle" />

and cycle.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
    android:cycles="4" />

now add animation on your code

Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
anyview.startAnimation(shake);

If you want vertical animation, change fromXdelta and toXdelta value to fromYdelta and toYdelta value

The post needs an update after the links option is deprecated.

Basically, links is no longer needed because its main purpose, making container reachable by another by adding environment variable, is included implicitly with network. When containers are placed in the same network, they are reachable by each other using their container name and other alias as host.

For docker run, --link is also deprecated and should be replaced by a custom network.

docker network create mynet
docker run -d --net mynet --name container1 my_image
docker run -it --net mynet --name container1 another_image

depends_on expresses start order (and implicitly image pulling order), which was a good side effect of links.

You shouldn't really be de-encrypting passwords.

You should be encrypting the password entered into your application and comparing against the encrypted password from the database.

Edit - and if this is because the password has been forgotten, then setup a mechanism to create a new password.

you can try this: 1. ensure you have added: compile 'com.android.support:design:25.3.1' (maybe you also should add compile 'com.android.support.constraint:constraint-layout:1.0.2') 2.

3.click the Infer Constraints, hope it can help you.

In case you need the answer to be a member of the input numpy array:

Just to add that the percentile function in numpy by default calculates the output as a linear weighted average of the two neighboring entries in the input vector. In some cases people may want the returned percentile to be an actual element of the vector, in this case, from v1.9.0 onwards you can use the "interpolation" option, with either "lower", "higher" or "nearest".

import numpy as np
x=np.random.uniform(10,size=(1000))-5.0

np.percentile(x,70) # 70th percentile

2.075966046220879

np.percentile(x,70,interpolation="nearest")

2.0729677997904314

The latter is an actual entry in the vector, while the former is a linear interpolation of two vector entries that border the percentile

To complement these other answers, the // operator also offers significant (3x) performance benefits over /, presuming you want integer division.

$ python -m timeit '20.5 // 2'
100,000,000 loops, best of 3: 14.9 nsec per loop

$ python -m timeit '20.5 / 2'
 10,000,000 loops, best of 3: 48.4 nsec per loop

$ python -m timeit '20 / 2'
 10,000,000 loops, best of 3: 43.0 nsec per loop

$ python -m timeit '20 // 2'
100,000,000 loops, best of 3: 14.4 nsec per loop

No, only using LIKE will not work. LIKE searches values matching exactly your given pattern. In this case LIKE would find only the text 'sOmeVal' and not 'someval'.

A pracitcable solution is using the LCASE() function. LCASE('sOmeVal') gets the lowercase string of your text: 'someval'. If you use this function for both sides of your comparison, it works:

SELECT * FROM myTable WHERE LCASE(myField) LIKE LCASE('sOmeVal')

The statement compares two lowercase strings, so that your 'sOmeVal' will match every other notation of 'someval' (e.g. 'Someval', 'sOMEVAl' etc.).

sc.nextLine() is better as compared to parsing the input. Because performance wise it will be good.

A couple more command-line mailer programs:

• mailsend
• Mail Alert Simple Mailer

Both support SSL too.

The 1s are because everything is perfectly correlated with itself, and the NAs are because there are NAs in your variables.

You will have to specify how you want R to compute the correlation when there are missing values, because the default is to only compute a coefficient with complete information.

You can change this behavior with the use argument to cor, see ?cor for details.

I know this is an old question, but I had a similar problem and wanted to post my solution in case it could benefit someone else. I encountered the problem while learning to use:

• ASP.NET 3.5
• C#
• VS2008

I was trying to create an AJAX-enabled page (look into a tutorial about using the ScriptManager object if you aren't familiar with this). I tried to access the HTML elements in the page via the C# code, and I was getting an error stating the the identifier for the HTML ID value "does not exist in the current context."

To solve it, I had to do the following:

1. Run at server

To access the HTML element as a variable in the C# code, the following value must be placed in the HTML element tag in the aspx file:

runat="server"

Some objects in the Toolbox in the Visual Studio IDE do not automatically include this value when added to the page.

2. Regenerate the auto-generated C# file:

• In the Solution Explorer, under the aspx file there should be two files: *.aspx.cs and *.aspx.designer.cs. The designer file is auto-generated.
• Delete the existing *.aspx.designer.cs file. Make sure you only delete the designer file. Do not delete the other one, because it contains your C# code for the page.
• Right-click on the parent aspx file. In the pop-up menu, select Convert to Web Application.

Now the element should be accessible in the C# code file.

I was getting this problem when using IBM RSA 9.6.1 when building a brand new development machine. The problem for me ended up being because of HTTPS on the Global Maven repository. My solution was to create a Maven settings.xml that forced it to use HTTP.

The key to me was that the central repository was empty when I exploded it under Maven Repositories -- > Global Repositories

Using the following settings file worked for me:

<settings>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>insecurecentral</activeProfile>
  </activeProfiles>
  <profiles>
    <profile>
      <id>insecurecentral</id>
      <!--Override the repository (and pluginRepository) "central" from the Maven Super POM -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://repo.maven.apache.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </repository>
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>central</id>
          <url>http://repo.maven.apache.org/maven2</url>
          <releases>
            <enabled>true</enabled>
          </releases>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
</settings>

I got the idea from this stackoverflow question.

The image you're using is Alpine based, so you can't use apt-get because it's Ubuntu's package manager.

To fix this just use:

apk update and apk add

Try this:

var itemsInCart = from o in db.OrderLineItems
                  where o.OrderId == currentOrder.OrderId
                  select o.WishListItem.Price;

return Convert.ToDecimal(itemsInCart.Sum());

I think it's more simple!

First, let me go over a few terms. If you just want your question answered, scroll down to "Answering your question".

Definitions

Object identity: When you create an object, you can assign it to a variable. You can then also assign it to another variable. And another.

>>> button = Button()
>>> cancel = button
>>> close = button
>>> dismiss = button
>>> print(cancel is close)
True

In this case, cancel, close, and dismiss all refer to the same object in memory. You only created one Button object, and all three variables refer to this one object. We say that cancel, close, and dismiss all refer to identical objects; that is, they refer to one single object.

Object equality: When you compare two objects, you usually don't care that it refers to the exact same object in memory. With object equality, you can define your own rules for how two objects compare. When you write if a == b:, you are essentially saying if a.__eq__(b):. This lets you define a __eq__ method on a so that you can use your own comparison logic.

Rationale for equality comparisons

Rationale: Two objects have the exact same data, but are not identical. (They are not the same object in memory.) Example: Strings

>>> greeting = "It's a beautiful day in the neighbourhood."
>>> a = unicode(greeting)
>>> b = unicode(greeting)
>>> a is b
False
>>> a == b
True

Note: I use unicode strings here because Python is smart enough to reuse regular strings without creating new ones in memory.

Here, I have two unicode strings, a and b. They have the exact same content, but they are not the same object in memory. However, when we compare them, we want them to compare equal. What's happening here is that the unicode object has implemented the __eq__ method.

class unicode(object):
    # ...

    def __eq__(self, other):
        if len(self) != len(other):
            return False

        for i, j in zip(self, other):
            if i != j:
                return False

        return True

Note: __eq__ on unicode is definitely implemented more efficiently than this.

Rationale: Two objects have different data, but are considered the same object if some key data is the same. Example: Most types of model data

>>> import datetime
>>> a = Monitor()
>>> a.make = "Dell"
>>> a.model = "E770s"
>>> a.owner = "Bob Jones"
>>> a.warranty_expiration = datetime.date(2030, 12, 31)
>>> b = Monitor()
>>> b.make = "Dell"
>>> b.model = "E770s"
>>> b.owner = "Sam Johnson"
>>> b.warranty_expiration = datetime.date(2005, 8, 22)
>>> a is b
False
>>> a == b
True

Here, I have two Dell monitors, a and b. They have the same make and model. However, they neither have the same data nor are the same object in memory. However, when we compare them, we want them to compare equal. What's happening here is that the Monitor object implemented the __eq__ method.

class Monitor(object):
    # ...

    def __eq__(self, other):
        return self.make == other.make and self.model == other.model

Answering your question

When comparing to None, always use is not. None is a singleton in Python - there is only ever one instance of it in memory.

By comparing identity, this can be performed very quickly. Python checks whether the object you're referring to has the same memory address as the global None object - a very, very fast comparison of two numbers.

By comparing equality, Python has to look up whether your object has an __eq__ method. If it does not, it examines each superclass looking for an __eq__ method. If it finds one, Python calls it. This is especially bad if the __eq__ method is slow and doesn't immediately return when it notices that the other object is None.

Did you not implement __eq__? Then Python will probably find the __eq__ method on object and use that instead - which just checks for object identity anyway.

When comparing most other things in Python, you will be using !=.

You can simply do it like this with an object literal:

function makeGamePlayer(name,totalScore,gamesPlayed) {
    return {
        name: name,
        totalscore: totalScore,
        gamesPlayed: gamesPlayed
    };
}

Besides && and || being short circuiting, also consider operator precedence when mixing the two forms. I think it will not be immediately apparent to everybody that result1 and result2 contain different values.

boolean a = true;
boolean b = false;
boolean c = false;

boolean result1 = a || b && c; //is true;  evaluated as a || (b && c)
boolean result2 = a  | b && c; //is false; evaluated as (a | b) && c

Don't store lists as strings; store them as arrays to avoid all this delimiter confusion. Here's an example script that'll either operate on all subdirectories of test, or the list supplied on its command line:

#!/bin/bash
if [ $# -eq 0 ]; then
        # if no args supplies, build a list of subdirs of test/
        dirlist=() # start with empty list
        for f in test/*; do # for each item in test/ ...
                if [ -d "$f" ]; then # if it's a subdir...
                        dirlist=("${dirlist[@]}" "$f") # add it to the list
                fi
        done
else
        # if args were supplied, copy the list of args into dirlist
        dirlist=("$@")
fi
# now loop through dirlist, operating on each one
for dir in "${dirlist[@]}"; do
        printf "Directory: %s\n" "$dir"
done

Now let's try this out on a test directory with a curve or two thrown in:

$ ls -F test
Baltimore/
Cherry Hill/
Edison/
New York City/
Philadelphia/
this is a dirname with quotes, lfs, escapes: "\''?'?\e\n\d/
this is a file, not a directory
$ ./test.sh 
Directory: test/Baltimore
Directory: test/Cherry Hill
Directory: test/Edison
Directory: test/New York City
Directory: test/Philadelphia
Directory: test/this is a dirname with quotes, lfs, escapes: "\''
'
\e\n\d
$ ./test.sh "Cherry Hill" "New York City"
Directory: Cherry Hill
Directory: New York City

You can not serialize a Python 3 'string' to bytes without explict conversion to some encoding.

outfile.write(plaintext.encode('utf-8'))

is possibly what you want. Also this works for both python 2.x and 3.x.

I'm using Visual Studio 2015, and I've found that the first thing to do is look in the build output.

I found this error reported there:

Reading build config file: \build.json... SyntaxError: Unexpected token

The solution for that was to remove the bom from the build.json file

Then I hit a second problem - with this message in the build output:

FAILURE: Build failed with an exception. * What went wrong: A problem was found with the configuration of task ':packageRelease'.

File 'C:\Users\Colin\etc' specified for property 'signingConfig.storeFile' is not a file.

Easily solved by putting the correct filename into the keystore property

You can't sort a Dictionary<TKey, TValue> - it's inherently unordered. (Or rather, the order in which entries are retrieved is implementation-specific. You shouldn't rely on it working the same way between versions, as ordering isn't part of its designed functionality.)

You can use SortedList<TKey, TValue> or SortedDictionary<TKey, TValue>, both of which sort by the key (in a configurable way, if you pass an IEqualityComparer<T> into the constructor) - might those be of use to you?

Pay little attention to the word "list" in the name SortedList - it's still a dictionary in that it maps keys to values. It's implemented using a list internally, effectively - so instead of looking up by hash code, it does a binary search. SortedDictionary is similarly based on binary searches, but via a tree instead of a list.

Update for Laravel 6

Now that Laravel 6 is released you need to install laravel/ui.

composer require laravel/ui --dev
php artisan ui vue --auth

You can change vue with react if you use React in your project (see Using React).

And then you need to perform the migrations and compile the frontend

php artisan migrate
npm install && npm run dev

Source : Laravel Documentation for authentication

Want to get started fast? Install the laravel/ui Composer package and run php artisan ui vue --auth in a fresh Laravel application. After migrating your database, navigate your browser to http://your-app.test/register or any other URL that is assigned to your application. These commands will take care of scaffolding your entire authentication system!

Note: That's only if you want to use scaffolding, you can use the default User model and the Eloquent authentication driver.

As a fallback there's always od -xc filename

To get the value from the servlet from POST command, you can follow the approach as explained on this post by using request.getParameter(key) format which will return the value you want.

You can use dict.pop:

 mydict.pop("key", None)

Note that if the second argument, i.e. None is not given, KeyError is raised if the key is not in the dictionary. Providing the second argument prevents the conditional exception.

To get all divs under 'container', use the following:

$(".container>div")  //or
$(".container").children("div");

You can stipulate a specific #id instead of div to get a particular one.

You say you want a div with an 'undefined' id. if I understand you right, the following would achieve this:

$(".container>div[id=]")

Source: https://nickjanetakis.com/blog/docker-tip-2-the-difference-between-copy-and-add-in-a-dockerile:

COPY and ADD are both Dockerfile instructions that serve similar purposes. They let you copy files from a specific location into a Docker image.

COPY takes in a src and destination. It only lets you copy in a local file or directory from your host (the machine building the Docker image) into the Docker image itself.

ADD lets you do that too, but it also supports 2 other sources. First, you can use a URL instead of a local file / directory. Secondly, you can extract a tar file from the source directly into the destination

A valid use case for ADD is when you want to extract a local tar file into a specific directory in your Docker image.

If you’re copying in local files to your Docker image, always use COPY because it’s more explicit.

All indexes with the zip function:

get_indexes = lambda x, xs: [i for (y, i) in zip(xs, range(len(xs))) if x == y]

print get_indexes(2, [1, 2, 3, 4, 5, 6, 3, 2, 3, 2])
print get_indexes('f', 'xsfhhttytffsafweef')

I came across this fairly recent (compared to the age of the question) TechNet article that includes some of the best techniques I could find on the topic:

WPF: Programmatically Selecting and Focusing a Row or Cell in a DataGrid

It includes details that should cover most requirements. It is important to remember that if you specify custom templates for the DataGridRow for some rows that these won't have DataGridCells inside and then the normal selection mechanisms of the grid doesn't work.

You'll need to be more specific on what datasource you've given the grid to answer the first part of your question, as the others have stated.

Hi Guys if u are using angular plugin in eclipse that time is plugin is limited periods after that if u want to used this plugin then u pay it so i suggest to you used webstrome and visual code ide that are very easy and comfort to used so take care if u start and developed a angular app using eclipse

Better to use android.R.drawable because it is public and documented.

Hello Friends Try This

1) How to Declare 2 File Provider in Manifest.

2) First Provider for file Download

3) second Provider used for camera and gallary

STEP 1

    </provider>

Provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths>
<files-path name="apks" path="." />
</paths>

Second Provider

     <provider
        android:name=".Utils.MyFileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true"

file_path.xml

<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="storage/emulated/0" path="."/>
</paths>

.Utils.MyFileProvider

Create Class MyFileProvider (only Create class no any method declare)

When you used File Provider used (.fileprovider) this name and you used for image (.provider) used this.

IF any one Problem to understand this code You can Contact on [email protected] i will help you.

malloc() (and its friends free() and realloc()) is the way to do this in C.

I believe this is what you are looking for:

Indexers (C# Programming Guide)

class SampleCollection<T>
{
    private T[] arr = new T[100];
    public T this[int i]
    {
        get => arr[i];
        set => arr[i] = value;
    }
}

// This class shows how client code uses the indexer
class Program
{
    static void Main(string[] args)
    {
        SampleCollection<string> stringCollection = 
            new SampleCollection<string>();
        stringCollection[0] = "Hello, World";
        System.Console.WriteLine(stringCollection[0]);
    }
}

Calling

for /?

in the command-line gives help about this syntax (which can be used outside FOR, too, this is just the place where help can be found).

In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file
%~$PATH:I   - searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

The modifiers can be combined to get compound results:

%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only
%~dp$PATH:I - searches the directories listed in the PATH
               environment variable for %I and expands to the
               drive letter and path of the first one found.
%~ftzaI     - expands %I to a DIR like output line

In the above examples %I and PATH can be replaced by other valid values. The %~ syntax is terminated by a valid FOR variable name. Picking upper case variable names like %I makes it more readable and avoids confusion with the modifiers, which are not case sensitive.

There are different letters you can use like f for "full path name", d for drive letter, p for path, and they can be combined. %~ is the beginning for each of those sequences and a number I denotes it works on the parameter %I (where %0 is the complete name of the batch file, just like you assumed).

It looks like Microsoft has deprecated lots of calls which use buffers to improve code security. However, the solutions they're providing aren't portable. Anyway, if you aren't interested in using the secure version of their calls (like fopen_s), you need to place a definition of _CRT_SECURE_NO_DEPRECATE before your included header files. For example:

#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>

The preprocessor directive can also be added to your project settings to effect it on all the files under the project. To do this add _CRT_SECURE_NO_DEPRECATE to Project Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions.

I've updated much of the code for Python 3 and threw it at perfplot (a project of mine) to see which is actually fastest. Turns out that, for large n, primesfrom{2,3}to takes the cake:

I tried t.boolean :active, :default => 1 in migration file for creating entire table. After ran that migration when i checked in db it made as null. Even though i told default as "1". After that slightly i changed migration file like this then it worked for me for setting default value on create table migration file.

t.boolean :active, :null => false,:default =>1. Worked for me.

My Rails framework version is 4.0.0

Remove the height will fix your problem because highchart is responsive by design if you adjust your screen it will also re-size.

I have removed it from my references.Then run this in Package Manager Console

Install-Package WebMatrix.Data

Finally add WebMatrix.WebData assembly to references,and rebuild project.It works for me.I hope it solves your problem too.

You should use heredoc or nowdoc.

$var = "some text";
$text = <<<EOT
  Place your text between the EOT. It's
  the delimiter that ends the text
  of your multiline string.
  $var
EOT;

The difference between heredoc and nowdoc is that PHP code embedded in a heredoc gets executed, while PHP code in nowdoc will be printed out as is.

$var = "foo";
$text = <<<'EOT'
  My $var
EOT;

In this case $text will have the value "My $var", not "My foo".

Notes:

• Before the closing EOT; there should be no spaces or tabs. otherwise you will get an error.
• The string/tag (EOT) that enclose the text is arbitrary, that is, one can use other strings, e.g. <<<FOO and FOO;
• EOT : End of transmission, EOD: End of data. ^[Q]

im use this code to and suggest you:

1) sudo sed -i -e 's|disco|eoan|g' /etc/apt/sources.list
2) sudo apt update

If you don't know the number of lines in your file, you don't have a size with which to init an array. In this case, it makes more sense to use a List :

List<String> tokens = new ArrayList<String>();
while (inFile1.hasNext()) {
    tokens.add(inFile1.nextLine());
}

After that, if you need to, you can copy to an array :

String[] tokenArray = tokens.toArray(new String[0]);

You can try this. Override the OnPaint event of the TextBox.

    protected override void OnPaint(PaintEventArgs e)
{
     SolidBrush drawBrush = new SolidBrush(ForeColor); //Use the ForeColor property
     // Draw string to screen.
     e.Graphics.DrawString(Text, Font, drawBrush, 0f,0f); //Use the Font property
}

set the ControlStyles to "UserPaint"

public MyTextBox()//constructor
{
     // This call is required by the Windows.Forms Form Designer.
     this.SetStyle(ControlStyles.UserPaint,true);

     InitializeComponent();

     // TODO: Add any initialization after the InitForm call
}

Refrence

Or you can try this hack

In Enter event set the focus

int index=this.Controls.IndexOf(this.textBox1);

this.Controls[index-1].Focus();

So your control will not focussed and behave like disabled.

From http://redis.io/topics/quickstart

wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make redis-cli
sudo cp src/redis-cli /usr/local/bin/

With Docker I normally use https://registry.hub.docker.com/_/redis/. If I need to add redis-cli to an image I use the following snippet.

RUN cd /tmp &&\
    curl http://download.redis.io/redis-stable.tar.gz | tar xz &&\
    make -C redis-stable &&\
    cp redis-stable/src/redis-cli /usr/local/bin &&\

Saving (w/o exception handling code):

FileOutputStream fos = context.openFileOutput(fileName, Context.MODE_PRIVATE);
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(this);
os.close();
fos.close();

Loading (w/o exception handling code):

FileInputStream fis = context.openFileInput(fileName);
ObjectInputStream is = new ObjectInputStream(fis);
SimpleClass simpleClass = (SimpleClass) is.readObject();
is.close();
fis.close();

Well after doing some more searching I discovered the error may be related to other issues as invalid keystores, passwords etc.

I then remembered that I had set two VM arguments for when I was testing SSL for my network connectivity.

I removed the following VM arguments to fix the problem:

-Djavax.net.ssl.keyStore=mySrvKeystore -Djavax.net.ssl.keyStorePassword=123456

Note: this keystore no longer exists so that's probably why the Exception.

We could type our variable with an explicit return type:

const script: HTMLScriptElement = document.getElementsByName(id).item(0);

Or assert as (needed with TSX):

const script = document.getElementsByName(id).item(0) as HTMLScriptElement;

Or in simpler cases assert with angle-bracket syntax.

A type assertion is like a type cast in other languages, but performs no special checking or restructuring of data. It has no runtime impact, and is used purely by the compiler.

Documentation:

TypeScript - Basic Types - Type assertions

Best:

 std::string subCondition;

This creates an empty string.

This:

std::string myStr = "";

does a copy initialization - creates a temporary string from "", and then uses the copy constructor to create myStr.

Bonus:

std::string myStr("");

does a direct initialization and uses the string(const char*) constructor.

To check if a string is empty, just use empty().

Following on from the answer by @marcel I found some functions were still missing on the cloned object. e.g.

function MyObject() {
  var methodAValue = null,
      methodBValue = null

  Object.defineProperty(this, "methodA", {
    get: function() { return methodAValue; },
    set: function(value) {
      methodAValue = value || {};
    },
    enumerable: true
  });

  Object.defineProperty(this, "methodB", {
    get: function() { return methodAValue; },
    set: function(value) {
      methodAValue = value || {};
    }
  });
}

where on MyObject I could clone methodA but methodB was excluded. This occurred because it is missing

enumerable: true

which meant it did not show up in

for(let key in item)

Instead I switched over to

Object.getOwnPropertyNames(item).forEach((key) => {
    ....
  });

which will include non-enumerable keys.

I also found that the prototype (proto) was not cloned. For that I ended up using

if (obj.__proto__) {
  copy.__proto__ = Object.assign(Object.create(Object.getPrototypeOf(obj)), obj);
}

PS: Frustrating that I could not find a built in function to do this.

You can use the native JS slice method:

<div v-for="item in shoppingItems.slice(0,10)">

The slice() method returns the selected elements in an array, as a new array object.

Based on tip in the migration guide: https://vuejs.org/v2/guide/migration.html#Replacing-the-limitBy-Filter

4 years later, ES6 way simpler version.

function getCookie(name) {
  let cookie = {};
  document.cookie.split(';').forEach(function(el) {
    let [k,v] = el.split('=');
    cookie[k.trim()] = v;
  })
  return cookie[name];
}

I have also created a gist to use it as a Cookie object. e.g., Cookie.set(name,value) and Cookie.get(name)

This read all cookies instead of scanning through. It's ok for small number of cookies.

    -o-transition: .5s all;   
    -o-transition-delay: 5s; 
    transition: .5s all;   
    transition-delay: 5s; 
}

div:hover {
    background:#5AC900;
    -webkit-transition-delay: 0s;
    -moz-transition-delay: 0s;
    -ms-transition-delay: 0s;
    -o-transition-delay: 0s;
    transition-delay: 0s;
}

This will add a transition delay, which will be applicable to almost every browser..

Do this :

<script type="text/javascript">
function showDetails(username)
{
   window.location = '/player_detail?username='+username;
}
</script>

<input type="button" name="theButton" value="Detail" onclick="showDetails('username');">

You can use MATCH for instance.

1. Select the column from the first cell, for example cell A2 to cell A100 and insert a conditional formatting, using 'New Rule...' and the option to conditional format based on a formula.

2. In the entry box, put:

   =MATCH(A2, 'Sheet2'!A:A, 0)
   

3. Pick the desired formatting (change the font to red or fill the cell background, etc) and click OK.

MATCH takes the value A2 from your data table, looks into 'Sheet2'!A:A and if there's an exact match (that's why there's a 0 at the end), then it'll return the row number.

Note: Conditional formatting based on conditions from other sheets is available only on Excel 2010 onwards. If you're working on an earlier version, you might want to get the list of 'Don't check' in the same sheet.

EDIT: As per new information, you will have to use some reverse matching. Instead of the above formula, try:

=SUM(IFERROR(SEARCH('Sheet2'!$A$1:$A$44, A2),0))

Detecting the HTTP method or so called REQUEST METHOD can be done using the following code snippet.

$method = $_SERVER['REQUEST_METHOD'];
if ($method == 'POST'){
    // Method is POST
} elseif ($method == 'GET'){
    // Method is GET
} elseif ($method == 'PUT'){
    // Method is PUT
} elseif ($method == 'DELETE'){
    // Method is DELETE
} else {
    // Method unknown
}

You could also do it using a switch if you prefer this over the if-else statement.

If a method other than GET or POST is required in an HTML form, this is often solved using a hidden field in the form.

<!-- DELETE method -->
<form action='' method='POST'>
    <input type="hidden" name'_METHOD' value="DELETE">
</form>

<!-- PUT method -->
<form action='' method='POST'>
    <input type="hidden" name'_METHOD' value="PUT">
</form>

For more information regarding HTTP methods I would like to refer to the following StackOverflow question:

HTTP protocol's PUT and DELETE and their usage in PHP

You can find the command line tools at the downloads page under the "Command line tools only" section.

• git revert is used to undo a previous commit. In git, you can't alter or erase an earlier commit. (Actually you can, but it can cause problems.) So instead of editing the earlier commit, revert introduces a new commit that reverses an earlier one.
• git reset is used to undo changes in your working directory that haven't been comitted yet.
• git checkout is used to copy a file from some other commit to your current working tree. It doesn't automatically commit the file.

Although we have great answers already, looking through a perspective of a beginner I'd like to add the additional information:

What does map(&:name) mean in Ruby?

This means, that you are passing another method as parameter to the map function. (In reality you're passing a symbol that gets converted into a proc. But this isn't that important in this particular case).

What is important is that you have a method named name that will be used by the map method as an argument instead of the traditional block style.

I have just copied and moved a Magento site to a local area so I could work on it offline and had the same problem.

But in the end I found out Magento was forcing a redirect from http to https and I didn't have a SSL setup. So this solved my problem http://www.magentocommerce.com/wiki/recover/ssl_access_with_phpmyadmin

It pretty much says set web/secure/use_in_adminhtml value from 1 to 0 in the core_config_data to allow non-secure access to the admin area

There're two kind of Django "projects" that I have in my ~/projects/ directory, both have a bit different structure.:

• Stand-alone websites
• Pluggable applications

Stand-alone website

Mostly private projects, but doesn't have to be. It usually looks like this:

~/projects/project_name/

docs/               # documentation
scripts/
  manage.py         # installed to PATH via setup.py
project_name/       # project dir (the one which django-admin.py creates)
  apps/             # project-specific applications
    accounts/       # most frequent app, with custom user model
    __init__.py
    ...
  settings/         # settings for different environments, see below
    __init__.py
    production.py
    development.py
    ...
        
  __init__.py       # contains project version
  urls.py
  wsgi.py
static/             # site-specific static files
templates/          # site-specific templates
tests/              # site-specific tests (mostly in-browser ones)
tmp/                # excluded from git
setup.py
requirements.txt
requirements_dev.txt
pytest.ini
...

Settings

The main settings are production ones. Other files (eg. staging.py, development.py) simply import everything from production.py and override only necessary variables.

For each environment, there are separate settings files, eg. production, development. I some projects I have also testing (for test runner), staging (as a check before final deploy) and heroku (for deploying to heroku) settings.

Requirements

I rather specify requirements in setup.py directly. Only those required for development/test environment I have in requirements_dev.txt.

Some services (eg. heroku) requires to have requirements.txt in root directory.

setup.py

Useful when deploying project using setuptools. It adds manage.py to PATH, so I can run manage.py directly (anywhere).

Project-specific apps

I used to put these apps into project_name/apps/ directory and import them using relative imports.

Templates/static/locale/tests files

I put these templates and static files into global templates/static directory, not inside each app. These files are usually edited by people, who doesn't care about project code structure or python at all. If you are full-stack developer working alone or in a small team, you can create per-app templates/static directory. It's really just a matter of taste.

The same applies for locale, although sometimes it's convenient to create separate locale directory.

Tests are usually better to place inside each app, but usually there is many integration/functional tests which tests more apps working together, so global tests directory does make sense.

Tmp directory

There is temporary directory in project root, excluded from VCS. It's used to store media/static files and sqlite database during development. Everything in tmp could be deleted anytime without any problems.

Virtualenv

I prefer virtualenvwrapper and place all venvs into ~/.venvs directory, but you could place it inside tmp/ to keep it together.

Project template

I've created project template for this setup, django-start-template

Deployment

Deployment of this project is following:

source $VENV/bin/activate
export DJANGO_SETTINGS_MODULE=project_name.settings.production
git pull
pip install -r requirements.txt

# Update database, static files, locales
manage.py syncdb  --noinput
manage.py migrate
manage.py collectstatic --noinput
manage.py makemessages -a
manage.py compilemessages

# restart wsgi
touch project_name/wsgi.py

You can use rsync instead of git, but still you need to run batch of commands to update your environment.

Recently, I made django-deploy app, which allows me to run single management command to update environment, but I've used it for one project only and I'm still experimenting with it.

Sketches and drafts

Draft of templates I place inside global templates/ directory. I guess one can create folder sketches/ in project root, but haven't used it yet.

Pluggable application

These apps are usually prepared to publish as open-source. I've taken example below from django-forme

~/projects/django-app/

docs/
app/
tests/
example_project/
LICENCE
MANIFEST.in
README.md
setup.py
pytest.ini
tox.ini
.travis.yml
...

Name of directories is clear (I hope). I put test files outside app directory, but it really doesn't matter. It is important to provide README and setup.py, so package is easily installed through pip.

The Android Developer Guide has a section called Building Custom Components. Unfortunately, the discussion of XML attributes only covers declaring the control inside the layout file and not actually handling the values inside the class initialisation. The steps are as follows:

1. Declare attributes in values\attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="MyCustomView">
        <attr name="android:text"/>
        <attr name="android:textColor"/>            
        <attr name="extraInformation" format="string" />
    </declare-styleable>
</resources>

Notice the use of an unqualified name in the declare-styleable tag. Non-standard android attributes like extraInformation need to have their type declared. Tags declared in the superclass will be available in subclasses without having to be redeclared.

2. Create constructors

Since there are two constructors that use an AttributeSet for initialisation, it is convenient to create a separate initialisation method for the constructors to call.

private void init(AttributeSet attrs) { 
    TypedArray a=getContext().obtainStyledAttributes(
         attrs,
         R.styleable.MyCustomView);

    //Use a
    Log.i("test",a.getString(
         R.styleable.MyCustomView_android_text));
    Log.i("test",""+a.getColor(
         R.styleable.MyCustomView_android_textColor, Color.BLACK));
    Log.i("test",a.getString(
         R.styleable.MyCustomView_extraInformation));

    //Don't forget this
    a.recycle();
}

R.styleable.MyCustomView is an autogenerated int[] resource where each element is the ID of an attribute. Attributes are generated for each property in the XML by appending the attribute name to the element name. For example, R.styleable.MyCustomView_android_text contains the android_text attribute for MyCustomView. Attributes can then be retrieved from the TypedArray using various get functions. If the attribute is not defined in the defined in the XML, then null is returned. Except, of course, if the return type is a primitive, in which case the second argument is returned.

If you don't want to retrieve all of the attributes, it is possible to create this array manually.The ID for standard android attributes are included in android.R.attr, while attributes for this project are in R.attr.

int attrsWanted[]=new int[]{android.R.attr.text, R.attr.textColor};

Please note that you should not use anything in android.R.styleable, as per this thread it may change in the future. It is still in the documentation as being to view all these constants in the one place is useful.

3. Use it in a layout files such as layout\main.xml

Include the namespace declaration xmlns:app="http://schemas.android.com/apk/res-auto" in the top level xml element. Namespaces provide a method to avoid the conflicts that sometimes occur when different schemas use the same element names (see this article for more info). The URL is simply a manner of uniquely identifying schemas - nothing actually needs to be hosted at that URL. If this doesn't appear to be doing anything, it is because you don't actually need to add the namespace prefix unless you need to resolve a conflict.

<com.mycompany.projectname.MyCustomView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent"
    android:text="Test text"
    android:textColor="#FFFFFF"
    app:extraInformation="My extra information"
/> 

Reference the custom view using the fully qualified name.

Android LabelView Sample

If you want a complete example, look at the android label view sample.

LabelView.java

 TypedArray a=context.obtainStyledAttributes(attrs, R.styleable.LabelView);
 CharSequences=a.getString(R.styleable.LabelView_text);

attrs.xml

<declare-styleable name="LabelView">
    <attr name="text"format="string"/>
    <attr name="textColor"format="color"/>
    <attr name="textSize"format="dimension"/>
</declare-styleable>

custom_view_1.xml

<com.example.android.apis.view.LabelView
    android:background="@drawable/blue"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    app:text="Blue" app:textSize="20dp"/>

This is contained in a LinearLayout with a namespace attribute: xmlns:app="http://schemas.android.com/apk/res-auto"

You can change it by going File => Settings (Shortcut CTRL+ ALT+ S) , from Left panel Choose Appearance , Now from Right Panel choose theme.

Android Studio 2.1

Preference -> Search for Appearance -> UI options , Click on DropDown Theme

Android 2.2

Android studio -> File -> Settings -> Appearance & Behavior -> Look for UI Options

EDIT :

Import External Themes

You can download custom theme from this website. Choose your theme, download it. To set theme Go to Android studio -> File -> Import Settings -> Choose the .jar file downloaded.

If you aren't sure how to run a rake task, first find out first what tasks you have and it will also list the commands to run the tasks.

Run rake --tasks on the terminal.

It will list the tasks like the following:

rake gobble:dev:prime             
rake gobble:dev:reset_number_of_kits                                    
rake gobble:dev:scrub_prod_data

You can then run your task with: rake gobble:dev:prime as listed.

I would simply use Path from Java 7

Path resourceDirectory = Paths.get("src","test","resources");

Neat and clean!

I'm afraid the DateTimePicker control doesn't have the ability to do those things. It's a pretty basic (and frustrating!) control. Your best option may be to find a third-party control that does what you want.

For the option of typing the date and time manually, you could build a custom component with a TextBox/DateTimePicker combination to accomplish this, and it might work reasonably well, if third-party controls are not an option.

you can use those function it's so easy the First one for encryption so you just call the function and send the text you wanna encrypt it and take the result from encryptWithAES function and send it to decrypt Function like this:

const CryptoJS = require("crypto-js");


   //The Function Below To Encrypt Text
   const encryptWithAES = (text) => {
      const passphrase = "My Secret Passphrase";
      return CryptoJS.AES.encrypt(text, passphrase).toString();
    };
    //The Function Below To Decrypt Text
    const decryptWithAES = (ciphertext) => {
      const passphrase = "My Secret Passphrase";
      const bytes = CryptoJS.AES.decrypt(ciphertext, passphrase);
      const originalText = bytes.toString(CryptoJS.enc.Utf8);
      return originalText;
    };

  let encryptText = encryptWithAES("YAZAN"); 
  //EncryptedText==>  //U2FsdGVkX19GgWeS66m0xxRUVxfpI60uVkWRedyU15I= 

  let decryptText = decryptWithAES(encryptText);
  //decryptText==>  //YAZAN 

From the MySQL 5.5 documentation:

One TIMESTAMP column in a table can have the current timestamp as the default value for initializing the column, as the auto-update value, or both. It is not possible to have the current timestamp be the default value for one column and the auto-update value for another column.

Changes in MySQL 5.6.5:

Previously, at most one TIMESTAMP column per table could be automatically initialized or updated to the current date and time. This restriction has been lifted. Any TIMESTAMP column definition can have any combination of DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP clauses. In addition, these clauses now can be used with DATETIME column definitions. For more information, see Automatic Initialization and Updating for TIMESTAMP and DATETIME.

In general, on GitHub, 1 repository = 1 project. For example: https://github.com/spring-projects/spring-boot . But it isn't a hard rule.

1 repository = many projects. For example: https://github.com/donhuvy/java_examples

1 projects = many repositories. For example: https://github.com/zendframework/zendframework (1 project named Zend Framework 3 has 61 + 1 = 62 repositories, don't believe? let count Zend Frameworks' modules + main repository)

I totally agree with @Brandon Ibbotson's comment:

A GitHub repository is just a "directory" where folders and files can exist.

You can convert it to char* if you don't need a modifiable string by using:

(char*) yourString.c_str();

This would be very useful when you want to publish a String variable via MQTT in arduino.

I use char 'f', 'm' and 'u' because I surmise the gender from name, voice and conversation, and sometimes don't know the gender. The final determination is their opinion.

It really depends how well you know the person and whether your criteria is physical form or personal identity. A psychologist might need additional options - cross to female, cross to male, trans to female, trans to male, hermaphrodite and undecided. With 9 options, not clearly defined by a single character, I might go with Hugo's advice of tiny integer.

Use a packet sniffer like Wireshark to look at what happens. You need to see a SYN-flagged packet outgoing, a SYN+ACK-flagged incoming and then a ACK-flagged outgoing. After that, the port is considered open on the local side.

If you only see the first packet and the error message comes after several seconds of waiting, the other side is not answering at all (like in: unplugged cable, overloaded server, misguided packet was discarded) and your local network stack aborts the connection attempt. If you see RST packets, the host actually denies the connection. If you see "ICMP Port unreachable" or host unreachable packets, a firewall or the target host inform you of the port actually being closed.

Of course you cannot expect the service to be available at all times (consider all the points of failure in between you and the data), so you should try again later.

I solved by deleting the derived data and this time it worked correctly. Tried with Xcode 7.3.1GM

You should be able to access the query using dot notation now.

If you want to access say you are receiving a GET request at /checkEmail?type=email&utm_source=xxxx&email=xxxxx&utm_campaign=XX and you want to fetch out the query used.

var type = req.query.type,
    email = req.query.email,
    utm = {
     source: req.query.utm_source,
     campaign: req.query.utm_campaign
    };

Params are used for the self defined parameter for receiving request, something like (example):

router.get('/:userID/food/edit/:foodID', function(req, res){
 //sample GET request at '/xavg234/food/edit/jb3552'

 var userToFind = req.params.userID;//gets xavg234
 var foodToSearch = req.params.foodID;//gets jb3552
 User.findOne({'userid':userToFind}) //dummy code
     .then(function(user){...})
     .catch(function(err){console.log(err)});
});

As another variation on Totem's known type solution, you can use reflection to create a generic type resolver to avoid the need to use known type attributes.

This uses a technique similar to Juval Lowy's GenericResolver for WCF.

As long as your base class is abstract or an interface, the known types will be automatically determined rather than having to be decorated with known type attributes.

In my own case I opted to use a $type property to designate type in my json object rather than try to determine it from the properties, though you could borrow from other solutions here to use property based determination.

 public class JsonKnownTypeConverter : JsonConverter
{
    public IEnumerable<Type> KnownTypes { get; set; }

    public JsonKnownTypeConverter() : this(ReflectTypes())
    {

    }
    public JsonKnownTypeConverter(IEnumerable<Type> knownTypes)
    {
        KnownTypes = knownTypes;
    }

    protected object Create(Type objectType, JObject jObject)
    {
        if (jObject["$type"] != null)
        {
            string typeName = jObject["$type"].ToString();
            return Activator.CreateInstance(KnownTypes.First(x => typeName == x.Name));
        }
        else
        {
            return Activator.CreateInstance(objectType);
        }
        throw new InvalidOperationException("No supported type");
    }

    public override bool CanConvert(Type objectType)
    {
        if (KnownTypes == null)
            return false;

        return (objectType.IsInterface || objectType.IsAbstract) && KnownTypes.Any(objectType.IsAssignableFrom);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        // Load JObject from stream
        JObject jObject = JObject.Load(reader);

        // Create target object based on JObject
        var target = Create(objectType, jObject);
        // Populate the object properties
        serializer.Populate(jObject.CreateReader(), target);
        return target;
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }

    //Static helpers
    static Assembly CallingAssembly = Assembly.GetCallingAssembly();

    static Type[] ReflectTypes()
    {
        List<Type> types = new List<Type>();
        var referencedAssemblies = Assembly.GetExecutingAssembly().GetReferencedAssemblies();
        foreach (var assemblyName in referencedAssemblies)
        {
            Assembly assembly = Assembly.Load(assemblyName);
            Type[] typesInReferencedAssembly = GetTypes(assembly);
            types.AddRange(typesInReferencedAssembly);
        }

        return types.ToArray();
    }

    static Type[] GetTypes(Assembly assembly, bool publicOnly = true)
    {
        Type[] allTypes = assembly.GetTypes();

        List<Type> types = new List<Type>();

        foreach (Type type in allTypes)
        {
            if (type.IsEnum == false &&
               type.IsInterface == false &&
               type.IsGenericTypeDefinition == false)
            {
                if (publicOnly == true && type.IsPublic == false)
                {
                    if (type.IsNested == false)
                    {
                        continue;
                    }
                    if (type.IsNestedPrivate == true)
                    {
                        continue;
                    }
                }
                types.Add(type);
            }
        }
        return types.ToArray();
    }

It can then be installed as a formatter

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Converters.Add(new JsonKnownTypeConverter());

I have encountered this problem a few times and in my case I uninstalled EntityFramework nuget package and installed EntityFrameworkCore nuget package, entityFramework.design and entityframework.tools
