A slight extension to the answer given, so, hopefully useful to the asker and anyone else looking.

You can also SELECT the values you want to delete. But watch out for the Error 1093 - You can't specify the target table for update in FROM clause.

DELETE FROM
    orders_products_history
WHERE
    (branchID, action) IN (
    SELECT
        branchID,
        action
    FROM
        (
        SELECT
            branchID,
            action
        FROM
            orders_products_history
        GROUP BY
            branchID,
            action
        HAVING
            COUNT(*) > 10000
        ) a
    );

I wanted to delete all history records where the number of history records for a single action/branch exceed 10,000. And thanks to this question and chosen answer, I can.

Hope this is of use.

I solved the problem by changing the compileSdkVersion in the Gradle.build file from 18 to 17.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 18
    }
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
}

Path.GetDirectoryName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName) Is the only one that has worked for me in every case I have tried.

Oneliner for doing all of the above operations:

for i in `ls -A .`; do if [ $i != ".git" ]; then rm -rf $i; fi; done; mv .git/* .; rm -rf .git; git config --bool core.bare true

(don't blame me if something blows up and you didn't have backups :P)

git log -1 --format="%an %ae%n%cn %ce" a2c25061

The Pretty Formats section of the git show documentation contains

• format:<string>

The format:<string> format allows you to specify which information you want to show. It works a little bit like printf format, with the notable exception that you get a newline with %n instead of \n …

The placeholders are:

• %an: author name
• %ae: author email
• %cn: committer name
• %ce: committer email

It's an old question but seems to me it wasn't completely answered, and I needed this information too so I'll post my answer.

If you want to use the Google Api Client Library, then you just need to have an access token that includes the refresh token in it, and then - even though the access token will expire after an hour - the library will refresh the token for you automatically.

In order to get an access token with a refresh token, you just need to ask for the offline access type (for example in PHP: $client->setAccessType("offline");) and you will get it. Just keep in mind you will get the access token with the refresh token only in the first authorization, so make sure to save that access token in the first time, and you will be able to use it anytime.

Hope that helps anyone :-)

The following was tested for IIS 8.5 and Windows 8.1.

As of IIS 7, Windows recommends restarting IIS via net stop/start. Via the command prompt (as Administrator):

> net stop WAS
> net start W3SVC

net stop WAS will stop W3SVC as well. Then when starting, net start W3SVC will start WAS as a dependency.

This is quite simple.

Assuming the data is stored in a column called A in a table called T, you can use

select A, count(A) from T group by A

This turned out to be a stupid error. My log4j wasn't configured to capture my error output. I was throwing configuration errors in the background and once I fixed those I was good to go and my request mappings worked fine.

I had this issue, it seems that I hadn't added the required NuGet packages, although I thought I had done so, make sure to check them, one by one.

Make sure your application.properties file is under src/main/resources/application.properties. Is one way to go. Then add @PostConstruct as follows

Sample Application.properties

file.directory = somePlaceOverHere

Sample Java Class

@ComponentScan
public class PrintProperty {

  @Value("${file.directory}")
  private String fileDirectory;

  @PostConstruct
  public void print() {
    System.out.println(fileDirectory);
  }
}

Code above will print out "somePlaceOverhere"

Here is a simple mathed to pass values from a route provider

        .then(function(res){

I'm using ubuntu 18.04 LTS release and I faced the same problem I tried to clean cache as above suggestions but it didn't work for me. However, I found another solution.

npm start

I run this command and it started to work

Default behavior in numpy is add componentwise

You need to put the iframe option in it's own context eg:

$(".someclass").fancybox({
    type : 'iframe',
    iframe : {
        scrolling : 'no'
    }
});

The problem was solved by reinstalling Visual Studio 2015.

It's this simple:

var a = [[12, 'AAA'], [58, 'BBB'], [28, 'CCC'],[18, 'DDD']];

a.sort(sortFunction);

function sortFunction(a, b) {
    if (a[0] === b[0]) {
        return 0;
    }
    else {
        return (a[0] < b[0]) ? -1 : 1;
    }
}

I invite you to read the documentation.

If you want to sort by the second column, you can do this:

a.sort(compareSecondColumn);

function compareSecondColumn(a, b) {
    if (a[1] === b[1]) {
        return 0;
    }
    else {
        return (a[1] < b[1]) ? -1 : 1;
    }
}

I wanted a simple example of the use of case that I could play with, this doesn't even need a table. This returns odd or even depending whether seconds is odd or even

SELECT CASE MOD(SECOND(NOW()),2) WHEN 0 THEN 'odd' WHEN 1 THEN 'even' END;

ssh-keygen -f private.pem -y > public.pub

Is that what you had in mind?

Here are the detailed steps needed to achieve this.

The existing commands can be simply run via the CLI terminal of VS-CODE. It is understood that Git is installed in the system, configured with desired username and email Id.

1) Navigate to the local project directory and create a local git repository:

 git init

2) Once that is successful, click on the 'Source Control' icon on the left navbar in VS-Code.One should be able to see files ready to be commit-ed. Press on 'Commit' button, provide comments, stage the changes and commit the files. Alternatively you can run from CLI

git commit -m "Your comment"

3) Now you need to visit your GitHub account and create a new Repository. Exclude creating 'README.md', '.gitIgnore' files. Also do not add any License to the repo. Sometimes these settings cause issue while pushing in.

4) Copy the link to this newly created GitHub Repository.

5) Come back to the terminal in VS-CODE and type these commands in succession:

git remote add origin <Link to GitHub Repo>     //maps the remote repo link to local git repo

git remote -v                                  //this is to verify the link to the remote repo 

git push -u origin master                      // pushes the commit-ed changes into the remote repo

Note: If it is the first time the local git account is trying to connect to GitHub, you may be required to enter credentials to GitHub in a separate window.

6) You can see the success message in the Terminal. You can also verify by refreshing the GitHub repo online.

Hope this helps

Create a Child Component that use ngOnChanges.

ChildComponent.ts::

import { Component, OnChanges, Input } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'child',
  templateUrl: 'child.component.html',
})

export class ChildComponent implements OnChanges {
  @Input() child_id;

  constructor(private route: ActivatedRoute) { }

  ngOnChanges() {
    // create header using child_id
    console.log(this.child_id);
  }
}

now use it in MasterComponent's template and pass data to ChildComponent like:

<child [child_id]="child_id"></child>

I was recently shown this website for liquid layouts using CSS. http://matthewjamestaylor.com/blog/perfect-multi-column-liquid-layouts (Take a look at the demo pages in the links below).

The author now provides an example for fixed width layouts. Check out; http://matthewjamestaylor.com/blog/how-to-convert-a-liquid-layout-to-fixed-width.

This provides the following example(s), http://matthewjamestaylor.com/blog/ultimate-2-column-left-menu-pixels.htm (for two column layout like you are after I think)

http://matthewjamestaylor.com/blog/fixed-width-or-liquid-layout.htm (for three column layout).

Sorry for so many links to this guys site, but I think it is an AWESOME resource.

First, in Python, if your code is CPU-bound, multithreading won't help, because only one thread can hold the Global Interpreter Lock, and therefore run Python code, at a time. So, you need to use processes, not threads.

This is not true if your operation "takes forever to return" because it's IO-bound—that is, waiting on the network or disk copies or the like. I'll come back to that later.

Next, the way to process 5 or 10 or 100 items at once is to create a pool of 5 or 10 or 100 workers, and put the items into a queue that the workers service. Fortunately, the stdlib multiprocessing and concurrent.futures libraries both wraps up most of the details for you.

The former is more powerful and flexible for traditional programming; the latter is simpler if you need to compose future-waiting; for trivial cases, it really doesn't matter which you choose. (In this case, the most obvious implementation with each takes 3 lines with futures, 4 lines with multiprocessing.)

If you're using 2.6-2.7 or 3.0-3.1, futures isn't built in, but you can install it from PyPI (pip install futures).

Finally, it's usually a lot simpler to parallelize things if you can turn the entire loop iteration into a function call (something you could, e.g., pass to map), so let's do that first:

def try_my_operation(item):
    try:
        api.my_operation(item)
    except:
        print('error with item')

Putting it all together:

executor = concurrent.futures.ProcessPoolExecutor(10)
futures = [executor.submit(try_my_operation, item) for item in items]
concurrent.futures.wait(futures)

If you have lots of relatively small jobs, the overhead of multiprocessing might swamp the gains. The way to solve that is to batch up the work into larger jobs. For example (using grouper from the itertools recipes, which you can copy and paste into your code, or get from the more-itertools project on PyPI):

def try_multiple_operations(items):
    for item in items:
        try:
            api.my_operation(item)
        except:
            print('error with item')

executor = concurrent.futures.ProcessPoolExecutor(10)
futures = [executor.submit(try_multiple_operations, group) 
           for group in grouper(5, items)]
concurrent.futures.wait(futures)

Finally, what if your code is IO bound? Then threads are just as good as processes, and with less overhead (and fewer limitations, but those limitations usually won't affect you in cases like this). Sometimes that "less overhead" is enough to mean you don't need batching with threads, but you do with processes, which is a nice win.

So, how do you use threads instead of processes? Just change ProcessPoolExecutor to ThreadPoolExecutor.

If you're not sure whether your code is CPU-bound or IO-bound, just try it both ways.

Can I do this for multiple functions in my python script? For example, if I had another for loop elsewhere in the code that I wanted to parallelize. Is it possible to do two multi threaded functions in the same script?

Yes. In fact, there are two different ways to do it.

First, you can share the same (thread or process) executor and use it from multiple places with no problem. The whole point of tasks and futures is that they're self-contained; you don't care where they run, just that you queue them up and eventually get the answer back.

Alternatively, you can have two executors in the same program with no problem. This has a performance cost—if you're using both executors at the same time, you'll end up trying to run (for example) 16 busy threads on 8 cores, which means there's going to be some context switching. But sometimes it's worth doing because, say, the two executors are rarely busy at the same time, and it makes your code a lot simpler. Or maybe one executor is running very large tasks that can take a while to complete, and the other is running very small tasks that need to complete as quickly as possible, because responsiveness is more important than throughput for part of your program.

If you don't know which is appropriate for your program, usually it's the first.

If you already have a service and want it to work all the time, you need to add 2 things:

1. in the service itself:

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

2. In the manifest:

   android:launchMode="singleTop"
   

No need to add bind unless you need it in the service.

You can also perform Implicit Type Conversions with template literals. Example:

let fruits = ["mango","orange","pineapple","papaya"];

console.log(`My favourite fruits are ${fruits}`);
// My favourite fruits are mango,orange,pineapple,papaya

gene_name = no_headers.iloc[1:,[1]]

This creates a DataFrame because you passed a list of columns (single, but still a list). When you later do this:

gene_name[x]

you now have a Series object with a single value. You can't hash the Series.

The solution is to create Series from the start.

gene_type = no_headers.iloc[1:,0]
gene_name = no_headers.iloc[1:,1]
disease_name = no_headers.iloc[1:,2]

Also, where you have orph_dict[gene_name[x]] =+ 1, I'm guessing that's a typo and you really mean orph_dict[gene_name[x]] += 1 to increment the counter.

Here is a rough explanation of the concepts.

[ACK] is the acknowledgement that the previously sent data packet was received.

[FIN] is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN).

So, suppose

• host A sends a data packet to host B
• and then host B wants to close the connection.
• Host B (depending on timing) can respond with [FIN,ACK] indicating that it received the sent packet and wants to close the session.
• Host A should then respond with a [FIN,ACK] indicating that it received the termination request (the ACK part) and that it too will close the connection (the FIN part).

However, if host A wants to close the session after sending the packet, it would only send a [FIN] packet (nothing to acknowledge) but host B would respond with [FIN,ACK] (acknowledges the request and responds with FIN).

Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST] instead of the usual [FIN,ACK]. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.

You can find a more detailed and comprehensive explanation here.

def total_subsets_matching_sum(numbers, sum):
    array = [1] + [0] * (sum)
    for current_number in numbers:
        for num in xrange(sum - current_number, -1, -1):
            if array[num]:
                array[num + current_number] += array[num]
    return array[sum]

assert(total_subsets_matching_sum(range(1, 10), 9)       == 8)
assert(total_subsets_matching_sum({1, 3, 2, 5, 4, 9}, 9) == 4)

Explanation

This is one of the classic problems. The idea is to find the number of possible sums with the current number. And its true that, there is exactly one way to bring sum to 0. At the beginning, we have only one number. We start from our target (variable Maximum in the solution) and subtract that number. If it is possible to get a sum of that number (array element corresponding to that number is not zero) then add it to the array element corresponding to the current number. The program would be easier to understand this way

for current_number in numbers:
    for num in xrange(sum, current_number - 1, -1):
        if array[num - current_number]:
            array[num] += array[num - current_number]

When the number is 1, there is only one way in which you can come up with the sum of 1 (1-1 becomes 0 and the element corresponding to 0 is 1). So the array would be like this (remember element zero will have 1)

[1, 1, 0, 0, 0, 0, 0, 0, 0, 0]

Now, the second number is 2. We start subtracting 2 from 9 and its not valid (since array element of 7 is zero we skip that) we keep doing this till 3. When its 3, 3 - 2 is 1 and the array element corresponding to 1 is 1 and we add it to the array element of 3. and when its 2, 2 - 2 becomes 0 and we the value corresponding to 0 to array element of 2. After this iteration the array looks like this

[1, 1, 1, 1, 0, 0, 0, 0, 0, 0]

We keep doing this till we process all the numbers and the array after every iteration looks like this

[1, 1, 0, 0, 0, 0, 0, 0, 0, 0]
[1, 1, 1, 1, 0, 0, 0, 0, 0, 0]
[1, 1, 1, 2, 1, 1, 1, 0, 0, 0]
[1, 1, 1, 2, 2, 2, 2, 2, 1, 1]
[1, 1, 1, 2, 2, 3, 3, 3, 3, 3]
[1, 1, 1, 2, 2, 3, 4, 4, 4, 5]
[1, 1, 1, 2, 2, 3, 4, 5, 5, 6]
[1, 1, 1, 2, 2, 3, 4, 5, 6, 7]
[1, 1, 1, 2, 2, 3, 4, 5, 6, 8]

After the last iteration, we would have considered all the numbers and the number of ways to get the target would be the array element corresponding to the target value. In our case, Array[9] after the last iteration is 8.

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

I created this and added to Site.css.

.img-responsive-center {
    display: block;
    height: auto;
    max-width: 100%;
    margin-left:auto;
    margin-right:auto;
}

You want to use transform this will return a Series with the index aligned to the df so you can then add it as a new column:

In [74]:

df = pd.DataFrame({'Date': ['2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05', '2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05'], 'Sym': ['aapl', 'aapl', 'aapl', 'aapl', 'aaww', 'aaww', 'aaww', 'aaww'], 'Data2': [11, 8, 10, 15, 110, 60, 100, 40],'Data3': [5, 8, 6, 1, 50, 100, 60, 120]})
?
df['Data4'] = df['Data3'].groupby(df['Date']).transform('sum')
df
Out[74]:
   Data2  Data3        Date   Sym  Data4
0     11      5  2015-05-08  aapl     55
1      8      8  2015-05-07  aapl    108
2     10      6  2015-05-06  aapl     66
3     15      1  2015-05-05  aapl    121
4    110     50  2015-05-08  aaww     55
5     60    100  2015-05-07  aaww    108
6    100     60  2015-05-06  aaww     66
7     40    120  2015-05-05  aaww    121

You can do it using dynamic instead of object:

dynamic item = AnyFunction(....);
string value = item.name;

Note that the Dynamic Language Runtime (DLR) has built-in caching mechanisms, so subsequent calls are very fast.

Please refer below TSQL. STRING_SPLIT function is available only under compatibility level 130 and above.

TSQL:

DECLARE @stringValue NVARCHAR(400) = 'red,blue,green,yellow,black'  
DECLARE @separator CHAR = ','

SELECT [value]  As Colour
FROM STRING_SPLIT(@stringValue, @separator); 

RESULT:

Colour

red blue green yellow black

getComboBox().addItemListener(this::comboBoxitemStateChanged);

so

public void comboBoxitemStateChanged(ItemEvent e) {
    if (e.getStateChange() == ItemEvent.SELECTED) {
        YourObject selectedItem = (YourObject) e.getItem();
        //TODO your actitons
    }
}

var log = { "page": window.location.href, 
        "item": "item", 
        "action": "action" };

log = JSON.stringify(log);
console.log(log);
console.log(JSON.parse(log));

//The output will be:

//For 1st Console is a String Like:

'{ "page": window.location.href,"item": "item","action": "action" }'

//For 2nd Console is a Object Like:

Object {
page   : window.location.href,  
item   : "item",
action : "action" }

Your class Delivery has no access modifier, which means it defaults to internal. If you then try to expose a property of that type as public, it won't work. Your type (class) needs to have the same, or higher access as your property.

Fixed. I was wrong: this only applies on element reassignment. I thought that the returned object wasn't referencing the new one.

It can be done.

Q: Why?
A: The get() method returns an object referencing the original one.

So, if you write myArrayList.get(15).itsVariable = 7
or
myArrayList.get(15).myMethod("My Value"),
you are actually assigning a value / using a method from the object referenced by the returned one (this means, the change is applied to the original object)

The only thing you can't do is myArrayList.get(15) = myNewElement. To do this you have to use list.set() method.

you can try to use cv2 like this

import cv2

image= cv2.imread('image page')

cv2.imshow('image', image)

cv2.waitKey(0)

cv2.destroyAllWindows()

Running assembly Code on Mac is just 3 steps away from you. It could be done using XCODE but better is to use NASM Command Line Tool. For My Ease I have already installed Xcode, if you have Xcode installed its good.

But You can do it without XCode as well.

Just Follow:

1. First Install NASM using Homebrew brew install nasm
2. convert .asm file into Obj File using this command nasm -f macho64 myFile.asm
3. Run Obj File to see OutPut using command ld -macosx_version_min 10.7.0 -lSystem -o OutPutFile myFile.o && ./64

Simple Text File named myFile.asm is written below for your convenience.

global start
section .text

start:
    mov     rax, 0x2000004 ; write
    mov     rdi, 1 ; stdout
    mov     rsi, msg
    mov     rdx, msg.len
    syscall

    mov     rax, 0x2000001 ; exit
    mov     rdi, 0
    syscall

section .data

msg:    db      "Assalam O Alaikum Dear", 10
.len:   equ     $ - msg

You would typically first read from the input stream and then close it. You can wrap the FileInputStream in another InputStream (or Reader). It will be automatically closed when you close the wrapping stream/reader.

If this is a method returning an InputStream to the caller, then it is the caller's responsibility to close the stream when finished with it. If you close it in your method, the caller will not be able to use it.

To answer some of your comments...

To send the contents InputStream to a remote consumer, you would write the content of the InputStream to an OutputStream, and then close both streams.

The remote consumer does not know anything about the stream objects you have created. He just receives the content, in an InputStream which he will create, read from and close.

Use the -e argument and the escape character \n:

echo -e "This will generate a next line \nThis new line is the result"

There is a massive difference in the example you have posted, the first version:

var urls = await context.Urls.ToListAsync();

This is bad, it basically does select * from table, returns all results into memory and then applies the where against that in memory collection rather than doing select * from table where... against the database.

The second method will not actually hit the database until a query is applied to the IQueryable (probably via a linq .Where().Select() style operation which will only return the db values which match the query.

If your examples were comparable, the async version will usually be slightly slower per request as there is more overhead in the state machine which the compiler generates to allow the async functionality.

However the major difference (and benefit) is that the async version allows more concurrent requests as it doesn't block the processing thread whilst it is waiting for IO to complete (db query, file access, web request etc).

First the bigint(20) not null auto_increment will not work, simply use bigserial primary key. Then datetime is timestamp in PostgreSQL. All in all:

CREATE TABLE article (
    article_id bigserial primary key,
    article_name varchar(20) NOT NULL,
    article_desc text NOT NULL,
    date_added timestamp default NULL
);

You can/should set your parameter to value to DBNull.Value;

if (variable == "")
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = DBNull.Value;
}
else
{
     cmd.Parameters.Add("@Param", SqlDbType.VarChar, 500).Value = variable;
}

Or you can leave your server side set to null and not pass the param at all.

You might do it this way:

function asoccArrayValueWithNumKey(&$arr, $key) {
   if (!(count($arr) > $key)) return false;
   reset($array);
   $aux   = -1;
   $found = false;
   while (($auxKey = key($array)) && !$found) {
      $aux++;
      $found = ($aux == $key);
   }
   if ($found) return $array[$auxKey];
   else return false;
}

$val = asoccArrayValueWithNumKey($array, 0);
$val = asoccArrayValueWithNumKey($array, 1);
etc...

Haven't tryed the code, but i'm pretty sure it will work.

Good luck!

The way to do this is near the top of the man page

grep -i -A 10 'error data'

Here is my answer, I am also using globals().items()

    def get_name_of_obj(obj, except_word = ""):

        for name, item in globals().items():
            if item == obj and name != except_word:
                return name

I added except_word because I want to filter off some word used in for loop. If you didn't add it, the keyword in for loop may confuse this function, sometimes the keyword like "each_item" in the following case may show in the function's result, depends on what you have done to your loop.

eg.

    for each_item in [objA, objB, objC]:
        get_name_of_obj(obj, "each_item")

eg.

    >>> objA = [1, 2, 3]
    >>> objB = ('a', {'b':'thi is B'}, 'c')
    >>> for each_item in [objA, objB]:
    ...     get_name_of_obj(each_item)
    ...
    'objA'
    'objB'
    >>>
    >>>
    >>> for each_item in [objA, objB]:
    ...     get_name_of_obj(each_item)
    ...
    'objA'
    'objB'
    >>>
    >>>
    >>> objC = [{'a1':'a2'}]
    >>>
    >>> for item in [objA, objB, objC]:
    ...     get_name_of_obj(item)
    ...
    'objA'
    'item'  <<<<<<<<<< --------- this is no good
    'item'
    >>> for item in [objA, objB]:
    ...     get_name_of_obj(item)
    ...
    'objA'
    'item'     <<<<<<<<--------this is no good
    >>>
    >>> for item in [objA, objB, objC]:
    ...     get_name_of_obj(item, "item")
    ...
    'objA'
    'objB'  <<<<<<<<<<--------- now it's ok
    'objC'
    >>>

Hope this can help.

I know what you mean, you want to trigger handleChange by click button.

But modify state value will not trigger onChange event, because onChange event is a form element event.

Steps to generate Create table DDLs for all the tables in the Hive database and export into text file to run later:

step 1)
create a .sh file with the below content, say hive_table_ddl.sh

#!/bin/bash
rm -f tableNames.txt
rm -f HiveTableDDL.txt
hive -e "use $1; show tables;" > tableNames.txt  
wait
cat tableNames.txt |while read LINE
   do
   hive -e "use $1;show create table $LINE;" >>HiveTableDDL.txt
   echo  -e "\n" >> HiveTableDDL.txt
   done
rm -f tableNames.txt
echo "Table DDL generated"

step 2)

Run the above shell script by passing 'db name' as paramanter

>bash hive_table_dd.sh <<databasename>>

output :

All the create table statements of your DB will be written into the HiveTableDDL.txt

It depends on your requirements, specially volume, users and frequency of search. But, for small or medium office, the best option is to use an application like Apple Photos or Adobe Lighroom. They are specialized to store, catalog, index, and organize this kind of resource. But, for large organizations, with strong requirements of storage and high number of users, it is recommend instantiate an Content Management plataform with a Digital Asset Management, like Nuxeo or Alfresco; both offers very good resources do manage very large volumes of data with simplified methods to retrive them. And, very important: there is an free (open source) option for both platforms.

Thanks for your post Joel, it helped me solve WPF's absence of support for animated GIFs. Just adding a little code since I had a heck of a time with setting the pictureBoxLoading.Image property due to the Winforms api.

I had to set my animated gif image's Build Action as "Content" and the Copy to output directory to "Copy if newer" or "always". Then in the MainWindow() I called this method. Only issue is that when I tried to dispose of the stream, it gave me a red envelope graphic instead of my image. I'll have to solve that problem. This removed the pain of loading a BitmapImage and changing it into a Bitmap (which obviously killed my animation because it is no longer a gif).

private void SetupProgressIcon()
{
   Uri uri = new Uri("pack://application:,,,/WPFTest;component/Images/animated_progress_apple.gif");
   if (uri != null)
   {
      Stream stream = Application.GetContentStream(uri).Stream;   
      imgProgressBox.Image = new System.Drawing.Bitmap(stream);
   }
}

In my case i wasn't exporting the module. module.exports = router;

I think what you are looking for is

Request.QueryString["QueryStringName"]

and you can access it on views by adding @

now look at my example,,, I generated a Url with QueryString

 var listURL = '@Url.RouteUrl(new { controller = "Sector", action = "List" , name = Request.QueryString["name"]})';

the listURL value is /Sector/List?name=value'

and when queryString is empty

listURL value is /Sector/List

MATLAB's FOR loop is static in nature; you cannot modify the loop variable between iterations, unlike the for(initialization;condition;increment) loop structure in other languages. This means that the following code always prints 1, 2, 3, 4, 5 regardless of the value of B.

A = 1:5;

for i = A
    A = B;
    disp(i);
end

If you want to be able to respond to changes in the data structure during iterations, a WHILE loop may be more appropriate --- you'll be able to test the loop condition at every iteration, and set the value of the loop variable(s) as you wish:

n = 10;
f = n;
while n > 1
    n = n-1;
    f = f*n;
end
disp(['n! = ' num2str(f)])

Btw, the for-each loop in Java (and possibly other languages) produces unspecified behavior when the data structure is modified during iteration. If you need to modify the data structure, you should use an appropriate Iterator instance which allows the addition and removal of elements in the collection you are iterating. The good news is that MATLAB supports Java objects, so you can do something like this:

A = java.util.ArrayList();
A.add(1);
A.add(2);
A.add(3);
A.add(4);
A.add(5);

itr = A.listIterator();

while itr.hasNext()

    k = itr.next();
    disp(k);

    % modify data structure while iterating
    itr.remove();
    itr.add(k);

end

pandas.isnull() (also pd.isna(), in newer versions) checks for missing values in both numeric and string/object arrays. From the documentation, it checks for:

NaN in numeric arrays, None/NaN in object arrays

Quick example:

import pandas as pd
import numpy as np
s = pd.Series(['apple', np.nan, 'banana'])
pd.isnull(s)
Out[9]: 
0    False
1     True
2    False
dtype: bool

The idea of using numpy.nan to represent missing values is something that pandas introduced, which is why pandas has the tools to deal with it.

Datetimes too (if you use pd.NaT you won't need to specify the dtype)

In [24]: s = Series([Timestamp('20130101'),np.nan,Timestamp('20130102 9:30')],dtype='M8[ns]')

In [25]: s
Out[25]: 
0   2013-01-01 00:00:00
1                   NaT
2   2013-01-02 09:30:00
dtype: datetime64[ns]``

In [26]: pd.isnull(s)
Out[26]: 
0    False
1     True
2    False
dtype: bool

Here's an awesome tool: Google Labs Browser Size

Generally it happens, because some browsers settings or plug-ins directly open PDF in the same window like a simple web page.

The following might help you. I have done it in PHP a few years back. But currently I'm not working on that platform.

<?php
    if (isset($_GET['file'])) {
        $file = $_GET['file'];
        if (file_exists($file) && is_readable($file) && preg_match('/\.pdf$/',$file)) {
            header('Content-type: application/pdf');
            header("Content-Disposition: attachment; filename=\"$file\"");
            readfile($file);
        }
    }
    else {
        header("HTTP/1.0 404 Not Found");
        echo "<h1>Error 404: File Not Found: <br /><em>$file</em></h1>";
    }
?>

Save the above as download.php.

Save this little snippet as a PHP file somewhere on your server and you can use it to make a file download in the browser, rather than display directly. If you want to serve files other than PDF, remove or edit line 5.

You can use it like so:

Add the following link to your HTML file.

<a href="download.php?file=my_pdf_file.pdf">Download the cool PDF.</a>

Reference from: This blog

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

Use

cd /d %Pathname%

or

pushd %Pathname%

instead.

For MySQL Workbench 8.0 navigate to:

Server > Data Import

A new tab called Administration - Data Import/Restore appears. There you can choose to import a Dump Project Folder or use a specific SQL file according to your needs. Then you must select a schema where the data will be imported to, or you have to click the New... button to type a name for the new schema.

Then you can select the database objects to be imported or just click the Start Import button in the lower right part of the tab area.

Having done that and if the import was successful, you'll need to update the Schema Navigator by clicking the arrow circle icon.

That's it!

For more detailed info, check the MySQL Workbench Manual: 6.5.2 SQL Data Export and Import Wizard

SHORTEST way (11 chars) in which you can do it is

I had this problem with a SOA system written in Java. I was running both the client and the server on different physical machines and they worked fine for a long time, then those nasty connection resets appeared in the client log and there wasn't anything strange in the server log. Restarting both client and server didn't solve the problem. Finally we discovered that the heap on the server side was rather full so we increased the memory available to the JVM: problem solved! Note that there was no OutOfMemoryError in the log: memory was just scarce, not exhausted.

The Servlet 2.4 specification says this about WEB-INF (page 70):

A special directory exists within the application hierarchy named WEB-INF. This directory contains all things related to the application that aren’t in the document root of the application. The WEB-INF node is not part of the public document tree of the application. No file contained in the WEB-INF directory may be served directly to a client by the container. However, the contents of the WEB-INF directory are visible to servlet code using the getResource and getResourceAsStream method calls on the ServletContext, and may be exposed using the RequestDispatcher calls.

This means that WEB-INF resources are accessible to the resource loader of your Web-Application and not directly visible for the public.

This is why a lot of projects put their resources like JSP files, JARs/libraries and their own class files or property files or any other sensitive information in the WEB-INF folder. Otherwise they would be accessible by using a simple static URL (usefull to load CSS or Javascript for instance).

Your JSP files can be anywhere though from a technical perspective. For instance in Spring you can configure them to be in WEB-INF explicitly:

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
    p:prefix="/WEB-INF/jsp/" 
    p:suffix=".jsp" >
</bean>

The WEB-INF/classes and WEB-INF/lib folders mentioned in Wikipedia's WAR files article are examples of folders required by the Servlet specification at runtime.

It is important to make the difference between the structure of a project and the structure of the resulting WAR file.

The structure of the project will in some cases partially reflect the structure of the WAR file (for static resources such as JSP files or HTML and JavaScript files, but this is not always the case.

The transition from the project structure into the resulting WAR file is done by a build process.

While you are usually free to design your own build process, nowadays most people will use a standardized approach such as Apache Maven. Among other things Maven defines defaults for which resources in the project structure map to what resources in the resulting artifact (the resulting artifact is the WAR file in this case). In some cases the mapping consists of a plain copy process in other cases the mapping process includes a transformation, such as filtering or compiling and others.

One example: The WEB-INF/classes folder will later contain all compiled java classes and resources (src/main/java and src/main/resources) that need to be loaded by the Classloader to start the application.

Another example: The WEB-INF/lib folder will later contain all jar files needed by the application. In a maven project the dependencies are managed for you and maven automatically copies the needed jar files to the WEB-INF/lib folder for you. That explains why you don't have a lib folder in a maven project.

You may write a proxy script for serving images - that's a bit more of work though. Something likes this:

HTML:

<img src="image.php?img=imageFile.jpg&some-random-number-262376" />

Script:

// PHP
if( isset( $_GET['img'] ) && is_file( IMG_PATH . $_GET['img'] ) ) {

  // read contents
  $f = open( IMG_PATH . $_GET['img'] );
  $img = $f.read();
  $f.close();

  // no-cache headers - complete set
  // these copied from [php.net/header][1], tested myself - works
  header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Some time in the past
  header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); 
  header("Cache-Control: no-store, no-cache, must-revalidate"); 
  header("Cache-Control: post-check=0, pre-check=0", false); 
  header("Pragma: no-cache"); 

  // image related headers
  header('Accept-Ranges: bytes');
  header('Content-Length: '.strlen( $img )); // How many bytes we're going to send
  header('Content-Type: image/jpeg'); // or image/png etc

  // actual image
  echo $img;
  exit();
}

Actually either no-cache headers or random number at image src should be sufficient, but since we want to be bullet proof..

Line from above answer:

HtmlDocument doc = new HtmlDocument();

This doesn't work in VS 2015 C#. You cannot construct an HtmlDocument any more.

Another MS "feature" that makes things more difficult to use. Try HtmlAgilityPack.HtmlWeb and check out this link for some sample code.

I find it very interesting that no one considered using UTC since it is not subject to DST. Therefore, I propose the following:

function daysIntoYear(date){
    return (Date.UTC(date.getFullYear(), date.getMonth(), date.getDate()) - Date.UTC(date.getFullYear(), 0, 0)) / 24 / 60 / 60 / 1000;
}

You can test it with the following:

[new Date(2016,0,1), new Date(2016,1,1), new Date(2016,2,1), new Date(2016,5,1), new Date(2016,11,31)]
    .forEach(d => 
        console.log(`${d.toLocaleDateString()} is ${daysIntoYear(d)} days into the year`));

Which outputs for the leap year 2016 (verified using http://www.epochconverter.com/days/2016):

1/1/2016 is 1 days into the year
2/1/2016 is 32 days into the year
3/1/2016 is 61 days into the year
6/1/2016 is 153 days into the year
12/31/2016 is 366 days into the year

I had a package-lock.json file from an old version of my package.json, I deleted that and then everything installed correctly.

Using Java 8 try with resources:

    StringBuilder stringBuilder = new StringBuilder();
    try(BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(request.getInputStream()))) {
        char[] charBuffer = new char[1024];
        int bytesRead;
        while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
            stringBuilder.append(charBuffer, 0, bytesRead);
        }
    }

When you define a function, you also define what info (arguments) that function needs to work. If it is designed to work without any additional info, and you pass it some, you are going to get that error.

Example: Takes no arguments:

def dog
end

Takes arguments:

def cat(name)
end

When you call these, you need to call them with the arguments you defined.

dog                  #works fine
cat("Fluffy")        #works fine


dog("Fido")          #Returns ArgumentError (1 for 0)
cat                  #Returns ArgumentError (0 for 1)

}

Lots of others have already advised you to rethink your code to make it more testable - good advice and usually simpler than what I'm about to suggest.

If you can't change the code to make it more testable, PowerMock: https://code.google.com/p/powermock/

PowerMock extends Mockito (so you don't have to learn a new mock framework), providing additional functionality. This includes the ability to have a constructor return a mock. Powerful, but a little complicated - so use it judiciously.

You use a different Mock runner. And you need to prepare the class that is going to invoke the constructor. (Note that this is a common gotcha - prepare the class that calls the constructor, not the constructed class)

@RunWith(PowerMockRunner.class)
@PrepareForTest({First.class})

Then in your test set-up, you can use the whenNew method to have the constructor return a mock

whenNew(Second.class).withAnyArguments().thenReturn(mock(Second.class));

.contains() is perfectly valid and a good way to check.

(http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/String.html#contains(java.lang.CharSequence))

Since you didn't post the error, I guess d is either null or you are getting the "Cannot refer to a non-final variable inside an inner class defined in a different method" error.

To make sure it's not null, first check for null in the if statement. If it's the other error, make sure d is declared as final or is a member variable of your class. Ditto for c.

section {
    position: relative;
    width: 50%;
    border: 1px solid;
}
h1 {
    display: inline;
}
div {
    position: relative;
    float:right;
    top: 0;
    right: 0;

}

The Basics

The simplist way to convert one date format into another is to use strtotime() with date(). strtotime() will convert the date into a Unix Timestamp. That Unix Timestamp can then be passed to date() to convert it to the new format.

$timestamp = strtotime('2008-07-01T22:35:17.02');
$new_date_format = date('Y-m-d H:i:s', $timestamp);

Or as a one-liner:

$new_date_format = date('Y-m-d H:i:s', strtotime('2008-07-01T22:35:17.02'));

Keep in mind that strtotime() requires the date to be in a valid format. Failure to provide a valid format will result in strtotime() returning false which will cause your date to be 1969-12-31.

Using DateTime()

As of PHP 5.2, PHP offered the DateTime() class which offers us more powerful tools for working with dates (and time). We can rewrite the above code using DateTime() as so:

$date = new DateTime('2008-07-01T22:35:17.02');
$new_date_format = $date->format('Y-m-d H:i:s');

Working with Unix timestamps

date() takes a Unix timeatamp as its second parameter and returns a formatted date for you:

$new_date_format = date('Y-m-d H:i:s', '1234567890');

DateTime() works with Unix timestamps by adding an @ before the timestamp:

$date = new DateTime('@1234567890');
$new_date_format = $date->format('Y-m-d H:i:s');

If the timestamp you have is in milliseconds (it may end in 000 and/or the timestamp is thirteen characters long) you will need to convert it to seconds before you can can convert it to another format. There's two ways to do this:

• Trim the last three digits off using substr()

Trimming the last three digits can be acheived several ways, but using substr() is the easiest:

$timestamp = substr('1234567899000', -3);

• Divide the substr by 1000

You can also convert the timestamp into seconds by dividing by 1000. Because the timestamp is too large for 32 bit systems to do math on you will need to use the BCMath library to do the math as strings:

$timestamp = bcdiv('1234567899000', '1000');

To get a Unix Timestamp you can use strtotime() which returns a Unix Timestamp:

$timestamp = strtotime('1973-04-18');

With DateTime() you can use DateTime::getTimestamp()

$date = new DateTime('2008-07-01T22:35:17.02');
$timestamp = $date->getTimestamp();

If you're running PHP 5.2 you can use the U formatting option instead:

$date = new DateTime('2008-07-01T22:35:17.02');
$timestamp = $date->format('U');

Working with non-standard and ambiguous date formats

Unfortunately not all dates that a developer has to work with are in a standard format. Fortunately PHP 5.3 provided us with a solution for that. DateTime::createFromFormat() allows us to tell PHP what format a date string is in so it can be successfully parsed into a DateTime object for further manipulation.

$date = DateTime::createFromFormat('F-d-Y h:i A', 'April-18-1973 9:48 AM');
$new_date_format = $date->format('Y-m-d H:i:s');

In PHP 5.4 we gained the ability to do class member access on instantiation has been added which allows us to turn our DateTime() code into a one-liner:

$new_date_format = (new DateTime('2008-07-01T22:35:17.02'))->format('Y-m-d H:i:s');

$new_date_format = DateTime::createFromFormat('F-d-Y h:i A', 'April-18-1973 9:48 AM')->format('Y-m-d H:i:s');

This provided a simple solution: Set data in Select2 after insert with AJAX

$("#select2").select2('data', {id: newID, text: newText});      

Try a category on UILabel:

Here's how it's used:

myLabel.text = @"Updated: 2012/10/14 21:59 PM";
[myLabel boldSubstring: @"Updated:"];
[myLabel boldSubstring: @"21:59 PM"];

And here's the category

UILabel+Boldify.h

- (void) boldSubstring: (NSString*) substring;
- (void) boldRange: (NSRange) range;

UILabel+Boldify.m

- (void) boldRange: (NSRange) range {
    if (![self respondsToSelector:@selector(setAttributedText:)]) {
        return;
    }
    NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithAttributedString:self.attributedText];
    [attributedText setAttributes:@{NSFontAttributeName:[UIFont boldSystemFontOfSize:self.font.pointSize]} range:range];

    self.attributedText = attributedText;    
}

- (void) boldSubstring: (NSString*) substring {
    NSRange range = [self.text rangeOfString:substring];
    [self boldRange:range];
}

Note that this will only work in iOS 6 and later. It will simply be ignored in iOS 5 and earlier.

Since the jar file 'executes' then it contains compiled java files known as .class files. You cannot import it to eclipse and modify the code. You should ask the supplier of the "demo" for the "source code". (or check the page you got the demo from for the source code)

Unless, you want to decompile the .class files and import to Eclipse. That may not be the case for starters.

Have you tried with Pandoc?

EDIT:

Although the documentation has become a bit complex, pandoc has supported inline LaTeX and LaTeX templates for 10 years.

Documents like the following one can be written in Markdown:

---
title: Just say hello!
author: My Friend
header-includes: |
    \usepackage{tikz,pgfplots}
    \usepackage{fancyhdr}
    \pagestyle{fancy}
    \fancyhead[CO,CE]{This is fancy}
    \fancyfoot[CO,CE]{So is this}
    \fancyfoot[LE,RO]{\thepage}
abstract: This is a pandoc test with Markdown + inline LaTeX
---

Just say hello!
===============

This could be a good example or inlined \LaTeX:

\begin{tikzpicture}
\begin{axis}
\addplot[color=red]{exp(x)};
\end{axis}
\end{tikzpicture}
%Here ends the furst plot
\hskip 5pt
%Here begins the 3d plot
\begin{tikzpicture}
\begin{axis}
\addplot3[
    surf,
]
{exp(-x^2-y^2)*x};
\end{axis}
\end{tikzpicture}

And now, just a few words to terminate:

> Goodbye folks!

Which can be converted to LaTeX using commands like this: pandoc -s -i Hello.md -o Hello.tex

Following is an image of the converted Hello.md to Hello.pdf file using MiKTeX as LaTeX processor with the command: pandoc -s -i Hello.md -o Hello.pdf

Finally, there are some open source LaTeX templates like this one: https://github.com/Wandmalfarbe/pandoc-latex-template, that can be used for better formatting.

As always, the reader should dig deeper if he has less trivial use cases than presented here.

you can use following command to create directory and give permissions at the same time

mkdir -m777 path/foldername 

You could use a watch instead, because that has the old and new value, but then you're adding to the digest cycle.

I'd just keep a second variable in the controller and set that.

For a reason I don't yet understand, after I used <%@include file="includes/footer.jsp" %> in my index.jsp then in the other jsp files like register.jsp I had to use <%@ include file="footer.jsp"%>. As you see there was no more need to use full path, STS had store my initial path.

You can convert the array objects into strings so they can be compared, add the strings to a Set so the comparable duplicates will be automatically removed and then convert each of the strings back into objects.

It might not be as performant as other answers, but it's readable.

const things = {};

things.thing = [];
things.thing.push({place:"here",name:"stuff"});
things.thing.push({place:"there",name:"morestuff"});
things.thing.push({place:"there",name:"morestuff"});

const uniqueArray = (arr) => {

  const stringifiedArray = arr.map((item) => JSON.stringify(item));
  const set = new Set(stringifiedArray);

  return Array.from(set).map((item) => JSON.parse(item));
}

const uniqueThings = uniqueArray(things.thing);

console.log(uniqueThings);

Try This:

HTML:

<div class="customselect">
    <select>
    <option>2000</option>
    <option>2001</option>
    <option>2002</option>
    </select>
</div>

CSS:

.customselect {
    width: 70px;
    overflow: hidden;
}

.customselect select {
   width: 100px;
   -moz-appearance: none;
   -webkit-appearance: none;
   appearance: none;
}

There's now a full-fledged plugin for that:

To understand this, you must take a step back. In OO, the customer owns the orders (orders are a list in the customer object). There can't be an order without a customer. So the customer seems to be the owner of the orders.

But in the SQL world, one item will actually contain a pointer to the other. Since there is 1 customer for N orders, each order contains a foreign key to the customer it belongs to. This is the "connection" and this means the order "owns" (or literally contains) the connection (information). This is exactly the opposite from the OO/model world.

This may help to understand:

public class Customer {
     // This field doesn't exist in the database
     // It is simulated with a SQL query
     // "OO speak": Customer owns the orders
     private List<Order> orders;
}

public class Order {
     // This field actually exists in the DB
     // In a purely OO model, we could omit it
     // "DB speak": Order contains a foreign key to customer
     private Customer customer;
}

The inverse side is the OO "owner" of the object, in this case the customer. The customer has no columns in the table to store the orders, so you must tell it where in the order table it can save this data (which happens via mappedBy).

Another common example are trees with nodes which can be both parents and children. In this case, the two fields are used in one class:

public class Node {
    // Again, this is managed by Hibernate.
    // There is no matching column in the database.
    @OneToMany(cascade = CascadeType.ALL) // mappedBy is only necessary when there are two fields with the type "Node"
    private List<Node> children;

    // This field exists in the database.
    // For the OO model, it's not really necessary and in fact
    // some XML implementations omit it to save memory.
    // Of course, that limits your options to navigate the tree.
    @ManyToOne
    private Node parent;
}

This explains for the "foreign key" many-to-one design works. There is a second approach which uses another table to maintain the relations. That means, for our first example, you have three tables: The one with customers, the one with orders and a two-column table with pairs of primary keys (customerPK, orderPK).

This approach is more flexible than the one above (it can easily handle one-to-one, many-to-one, one-to-many and even many-to-many). The price is that

• it's a bit slower (having to maintain another table and joins uses three tables instead of just two),
• the join syntax is more complex (which can be tedious if you have to manually write many queries, for example when you try to debug something)
• it's more error prone because you can suddenly get too many or too few results when something goes wrong in the code which manages the connection table.

That's why I rarely recommend this approach.

In connection string, the first string is the base in web.config

SchedulingContext is the base parameter of Entity file.

<connectionStrings>
     <add name="SchedulingContext" connectionString="Data Source=XXX\SQL2008R2DEV;Initial Catalog=YYY;Persist Security Info=True;User ID=sa;Password=XXX"   providerName="System.Data.SqlClient"/>

I am not sure, but maybe this logic would work.

var d = 10;
var prevDate = "";
var x = 0;
var oldVal = "";
var func = function (d) {
    if (x == 0 && d != prevDate && prevDate == "") {
        oldVal = d;
        prevDate = d;
    }
    else if (x == 1 && prevDate != d) {
        oldVal = prevDate;
        prevDate = d;
    }
    console.log(oldVal);
    x = 1;
};
/*
         ============================================
         Try:
         func(2);
         func(3);
         func(4);
*/

The workaround I used was a LifeCycleCallback. Still waiting to see if there is any more "native" method, for instance @Column(type="string", default="hello default value").

/**
 * @Entity @Table(name="posts") @HasLifeCycleCallbacks
 */
class Post implements Node, \Zend_Acl_Resource_Interface {

...

/**
 * @PrePersist
 */
function onPrePersist() {
    // set default date
    $this->dtPosted = date('Y-m-d H:m:s');
}

use std::map< std::string, std::map<std::string, std::string> >::const_iterator when map is const.

Here is a real world example which shows front/mid/back end.

General description:

• Frontend is responsible for presenting data to user. Please note interesting quirk that you may have two different front ends associated with single backend
• Backend provides business logic/data persistence.
• Middleware (activemq in the picture) is responsible for system to system. integration between backends. Usually it is installed as separate application

Overlapping:

It is possible to have overlapping between frontend and backend. This usually leaads to long-term issues with application maintenance and scalability. Fairly common in legacy applications.

Most modern technology stacks encourage developers to have strict separation. For example in the picture you can see that backend of the first system has rest web service which is a clear separation line.

Bottlenecks

Most bottlenecks in large are caused by database/network. Databases are located in backend. As for network issues every connection goes through netowrk, so every connection has potential for being slow. With good application design these issues are avoidable to large extend.

The important thing is one of the elements of calculation be a float-double type. Then to get a double result you need to cast this element like shown below:

c = static_cast<double>(a) / b;

or c = a / static_cast(b);

Or you can create it directly::

c = 7.0 / 3;

Note that one of elements of calculation must have the '.0' to indicate a division of a float-double type by an integer. Otherwise, despite the c variable be a double, the result will be zero too (an integer).

It should be much faster to use Newton's method to calculate the Integer Square Root, then square this number and check, as you do in your current solution. Newton's method is the basis for the Carmack solution mentioned in some other answers. You should be able to get a faster answer since you're only interested in the integer part of the root, allowing you to stop the approximation algorithm sooner.

Another optimization that you can try: If the Digital Root of a number doesn't end in 1, 4, 7, or 9 the number is not a perfect square. This can be used as a quick way to eliminate 60% of your inputs before applying the slower square root algorithm.

A more modern solution uses only purrr::transpose:

library(purrr)
iris[1:2,] %>% purrr::transpose()
#> [[1]]
#> [[1]]$Sepal.Length
#> [1] 5.1
#> 
#> [[1]]$Sepal.Width
#> [1] 3.5
#> 
#> [[1]]$Petal.Length
#> [1] 1.4
#> 
#> [[1]]$Petal.Width
#> [1] 0.2
#> 
#> [[1]]$Species
#> [1] 1
#> 
#> 
#> [[2]]
#> [[2]]$Sepal.Length
#> [1] 4.9
#> 
#> [[2]]$Sepal.Width
#> [1] 3
#> 
#> [[2]]$Petal.Length
#> [1] 1.4
#> 
#> [[2]]$Petal.Width
#> [1] 0.2
#> 
#> [[2]]$Species
#> [1] 1

I was recieving the same error when I was tring to call an object element by using another objects return value like;

$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes

$this->array2->$this->array1->country;// Error line

The above code was throwing the error and I tried many ways to fix it like; calling this part $this->array1->country in another function as return value, (string), taking it into quotations etc. I couldn't even find the solution on the web then i realised that the solution was very simple. All you have to do it wrap it with curly brackets and that allows you to target an object with another object's element value. like;

$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes

$this->array2->{$this->array1->country};

If anyone facing the same and couldn't find the answer, I hope this can help because i spend a night for this simple solution =)

You need to configure the remote first, then push.

git remote add origin url-to-your-repo

Actual Instructions

adapting the accepted answer to windows powershell:

Split-Path -Leaf (git symbolic-ref HEAD)

convert into string and then you can count tatal no of digit by .length method. Like:

String numberString = "855865264".toString();
int NumLen = numberString .Length;

Solr I am not sure but you can delete all the data from hbase using truncate command like below:

truncate 'table_name'

It will delete all row-keys from hbase table.

Use the android.webkit.URLUtil on android:

URLUtil.isValidUrl(URL_STRING);

Note: It is just checking the initial scheme of URL, not that the entire URL is valid.

You are already doing it in your code. Run this example below. The catch will "handle" the exception, and you can move forward, assuming whatever you caught and handled did not break code down the road which you did not anticipate.

 try{
      throw new Exception();
 }catch (Exception ex){
   ex.printStackTrace();
 }
 System.out.println("Made it!");

However, you should always handle an exception properly. You can get yourself into some pretty messy situations and write difficult to maintain code by "ignoring" exceptions. You should only do this if you are actually handling whatever went wrong with the exception to the point that it really does not affect the rest of the program.

Each image has a resource-number, which is an integer. Pass this number to "setImageResource" and you should be ok.

Check this link for further information:
http://developer.android.com/guide/topics/resources/accessing-resources.html

e.g.:

imageView.setImageResource(R.drawable.myimage);

to do it we have to know the three components

1. the place responsible for firing the Event
2. the place responsible for responding to the Event

3. the Event itself

   a. Event

   b .EventArgs

   c. EventArgs enumeration

now lets create Event that fired when a function is called

but I my order of solving this problem like this: I'm using the class before I create it

1. the place responsible for responding to the Event

   NetLog.OnMessageFired += delegate(object o, MessageEventArgs args) 
   {
           // when the Event Happened I want to Update the UI
           // this is WPF Window (WPF Project)  
           this.Dispatcher.Invoke(() =>
           {
               LabelFileName.Content = args.ItemUri;
               LabelOperation.Content = args.Operation;
               LabelStatus.Content = args.Status;
           });
   };
   

NetLog is a static class I will Explain it later

the next step is

2. the place responsible for firing the Event

   //this is the sender object, MessageEventArgs Is a class I want to create it  and Operation and Status are Event enums
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Started));
   downloadFile = service.DownloadFile(item.Uri);
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Finished));
   

the third step

3. the Event itself

I warped The Event within a class called NetLog

public sealed class NetLog
{
    public delegate void MessageEventHandler(object sender, MessageEventArgs args);

    public static event MessageEventHandler OnMessageFired;
    public static void FireMessage(Object obj,MessageEventArgs eventArgs)
    {
        if (OnMessageFired != null)
        {
            OnMessageFired(obj, eventArgs);
        }
    }
}

public class MessageEventArgs : EventArgs
{
    public string ItemUri { get; private set; }
    public Operation Operation { get; private set; }
    public Status Status { get; private set; }

    public MessageEventArgs(string itemUri, Operation operation, Status status)
    {
        ItemUri = itemUri;
        Operation = operation;
        Status = status;
    }
}

public enum Operation
{
    Upload,Download
}

public enum Status
{
    Started,Finished
}

this class now contain the Event, EventArgs and EventArgs Enums and the function responsible for firing the event

sorry for this long answer

If you really want to split every word (bash meaning) into a different array index completely changing the array in every while loop iteration, @ruakh's answer is the correct approach. But you can use the read property to split every read word into different variables column1, column2, column3 like in this code snippet

while IFS=$'\t' read -r column1 column2 column3 ; do
  printf "%b\n" "column1<${column1}>"
  printf "%b\n" "column2<${column2}>"
  printf "%b\n" "column3<${column3}>"
done < "myfile"

to reach a similar result avoiding array index access and improving your code readability by using meaningful variable names (of course using columnN is not a good idea to do so).

For Windows (7), the same folder is located at,

%APPDATA%\Subversion\auth

Type in the above in the Run(Win key + R) dialog box and hit Enter,

To check the existing username open the below file as a text file,

Using PHP's mail() function it's possible. Remember mail function will not work on a Local server.

<?php
$to      = '[email protected]';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: [email protected]' . "\r\n" .
    'Reply-To: [email protected]' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
?>

In XML:

android:divider="@null"

Or in Java:

listView.setDivider(null);

select CONVERT(NVARCHAR, SYSDATETIME(), 106) AS [DD-MON-YYYY]

or else

select REPLACE(CONVERT(NVARCHAR,GETDATE(), 106), ' ', '-')

both works fine

try it:

EXEC [ServerName].[DatabaseName].dbo.sp_columns 'TableName'

and you can get some table structure information, such as:

TABLE_QUALIFIER, TABLE_OWNER, TABLE_NAME, COLUMN_NAME, DATA_TYPE, TYPE_NAME...

Your regular expression should look like:

/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])[0-9a-zA-Z]{8,}$/

Here is an explanation:

/^
  (?=.*\d)          // should contain at least one digit
  (?=.*[a-z])       // should contain at least one lower case
  (?=.*[A-Z])       // should contain at least one upper case
  [a-zA-Z0-9]{8,}   // should contain at least 8 from the mentioned characters
$/

X-code is primarily made for OS-X or iPhone development on Mac systems. Versions for Windows are not available. However this might help!

There is no way to get Xcode on Windows; however you can use a different SDK like Corona instead although it will not use Objective-C (I believe it uses Lua). I have however heard that it is horrible to use.

The easiest solution is to toggleClass() both classes individually.

Let's say you have an icon:

    <i id="target" class="fa fa-angle-down"></i>

To toggle between fa-angle-down and fa-angle-up do the following:

    $('.sometrigger').click(function(){
        $('#target').toggleClass('fa-angle-down');
        $('#target').toggleClass('fa-angle-up');
    });

Since we had fa-angle-down at the beginning without fa-angle-up each time you toggle both, one leaves for the other to appear.

And now a keys iterator for range-based for loop.

template<typename C>
class keys_it
{
    typename C::const_iterator it_;
public:
    using key_type        = typename C::key_type;
    using pointer         = typename C::key_type*;
    using difference_type = std::ptrdiff_t;

    keys_it(const typename C::const_iterator & it) : it_(it) {}

    keys_it         operator++(int               ) /* postfix */ { return it_++         ; }
    keys_it&        operator++(                  ) /*  prefix */ { ++it_; return *this  ; }
    const key_type& operator* (                  ) const         { return it_->first    ; }
    const key_type& operator->(                  ) const         { return it_->first    ; }
    keys_it         operator+ (difference_type v ) const         { return it_ + v       ; }
    bool            operator==(const keys_it& rhs) const         { return it_ == rhs.it_; }
    bool            operator!=(const keys_it& rhs) const         { return it_ != rhs.it_; }
};

template<typename C>
class keys_impl
{
    const C & c;
public:
    keys_impl(const C & container) : c(container) {}
    const keys_it<C> begin() const { return keys_it<C>(std::begin(c)); }
    const keys_it<C> end  () const { return keys_it<C>(std::end  (c)); }
};

template<typename C>
keys_impl<C> keys(const C & container) { return keys_impl<C>(container); }

Usage:

std::map<std::string,int> my_map;
// fill my_map
for (const std::string & k : keys(my_map))
{
    // do things
}

That's what i was looking for. But nobody had it, it seems.

You get my OCD code alignment as a bonus.

As an exercise, write your own for values(my_map)

<mvc:annotation-driven /> means that you can define spring beans dependencies without actually having to specify a bunch of elements in XML or implement an interface or extend a base class. For example @Repository to tell spring that a class is a Dao without having to extend JpaDaoSupport or some other subclass of DaoSupport. Similarly @Controller tells spring that the class specified contains methods that will handle Http requests without you having to implement the Controller interface or extend a subclass that implements the controller.

When spring starts up it reads its XML configuration file and looks for <bean elements within it if it sees something like <bean class="com.example.Foo" /> and Foo was marked up with @Controller it knows that the class is a controller and treats it as such. By default, Spring assumes that all the classes it should manage are explicitly defined in the beans.XML file.

Component scanning with <context:component-scan base-package="com.mycompany.maventestwebapp" /> is telling spring that it should search the classpath for all the classes under com.mycompany.maventestweapp and look at each class to see if it has a @Controller, or @Repository, or @Service, or @Component and if it does then Spring will register the class with the bean factory as if you had typed <bean class="..." /> in the XML configuration files.

In a typical spring MVC app you will find that there are two spring configuration files, a file that configures the application context usually started with the Spring context listener.

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

And a Spring MVC configuration file usually started with the Spring dispatcher servlet. For example.

<servlet>
        <servlet-name>main</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>main</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

Spring has support for hierarchical bean factories, so in the case of the Spring MVC, the dispatcher servlet context is a child of the main application context. If the servlet context was asked for a bean called "abc" it will look in the servlet context first, if it does not find it there it will look in the parent context, which is the application context.

Common beans such as data sources, JPA configuration, business services are defined in the application context while MVC specific configuration goes not the configuration file associated with the servlet.

Hope this helps.

If you are running a modern Intel processor make sure HAXM (Intel® Hardware Accelerated Execution Manager) is installed:

1. In Android SDK Manager, ensure the option is ticked (and then installed)

2. Run the HAXM installer via the path below:

   your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe
   or
   your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-android.exe
   

This video shows all the required steps which may help you to solve the problem.

For AMD CPUs (or older Intel CPUs without VT-x technology), you will not be able to install this and the best option is to emulate your apps using Genymotion. See: Intel's HAXM equivalent for AMD on Windows OS

A simple way is to got to http://websitename.com:174, and you will be entering through a different port.

Using Moment library, see their website -> https://momentjs.com/timezone/docs/#/using-timezones/converting-to-zone/

i notice they also user their own library in their website, so you can have a try using the browser console before installing it

moment().tz(String);

The moment#tz mutator will change the time zone and update the offset.

moment("2013-11-18").tz("America/Toronto").format('Z'); // -05:00
moment("2013-11-18").tz("Europe/Berlin").format('Z');   // +01:00

This information is used consistently in other operations, like calculating the start of the day.

var m = moment.tz("2013-11-18 11:55", "America/Toronto");
m.format();                     // 2013-11-18T11:55:00-05:00
m.startOf("day").format();      // 2013-11-18T00:00:00-05:00
m.tz("Europe/Berlin").format(); // 2013-11-18T06:00:00+01:00
m.startOf("day").format();      // 2013-11-18T00:00:00+01:00

Without an argument, moment#tz returns:

Package graphql-type-json supports custom-scalars type JSON. Use it can show all the field of your json objects. Here is the link of the example in ApolloGraphql Server. https://www.apollographql.com/docs/apollo-server/schema/scalars-enums/#custom-scalars

Some rules of thumb for subprocess.

• Never use shell=True. It needlessly invokes an extra shell process to call your program.
• When calling processes, arguments are passed around as lists. sys.argv in python is a list, and so is argv in C. So you pass a list to Popen to call subprocesses, not a string.
• Don't redirect stderr to a PIPE when you're not reading it.
• Don't redirect stdin when you're not writing to it.

Example:

import subprocess, time, os, sys
cmd = ["rsync.exe", "-vaz", "-P", "source/" ,"dest/"]

p = subprocess.Popen(cmd,
                     stdout=subprocess.PIPE,
                     stderr=subprocess.STDOUT)

for line in iter(p.stdout.readline, b''):
    print(">>> " + line.rstrip())

That said, it is probable that rsync buffers its output when it detects that it is connected to a pipe instead of a terminal. This is the default behavior - when connected to a pipe, programs must explicitly flush stdout for realtime results, otherwise standard C library will buffer.

To test for that, try running this instead:

cmd = [sys.executable, 'test_out.py']

and create a test_out.py file with the contents:

import sys
import time
print ("Hello")
sys.stdout.flush()
time.sleep(10)
print ("World")

Executing that subprocess should give you "Hello" and wait 10 seconds before giving "World". If that happens with the python code above and not with rsync, that means rsync itself is buffering output, so you are out of luck.

A solution would be to connect direct to a pty, using something like pexpect.

It is usually much faster to script out all the objects in the database, and create an empty one, that to delete from or truncate tables.

I have published a header file to perform the switch on the strings in C. It contains a set of macro that hide the call to the strcmp() (or similar) in order to mimic a switch-like behaviour. I have tested it only with GCC in Linux, but I'm quite sure that it can be adapted to support other environment.

EDIT: added the code here, as requested

This is the header file you should include:

#ifndef __SWITCHS_H__
#define __SWITCHS_H__

#include <string.h>
#include <regex.h>
#include <stdbool.h>

/** Begin a switch for the string x */
#define switchs(x) \
    { char *__sw = (x); bool __done = false; bool __cont = false; \
        regex_t __regex; regcomp(&__regex, ".*", 0); do {

/** Check if the string matches the cases argument (case sensitive) */
#define cases(x)    } if ( __cont || !strcmp ( __sw, x ) ) \
                        { __done = true; __cont = true;

/** Check if the string matches the icases argument (case insensitive) */
#define icases(x)    } if ( __cont || !strcasecmp ( __sw, x ) ) { \
                        __done = true; __cont = true;

/** Check if the string matches the specified regular expression using regcomp(3) */
#define cases_re(x,flags) } regfree ( &__regex ); if ( __cont || ( \
                              0 == regcomp ( &__regex, x, flags ) && \
                              0 == regexec ( &__regex, __sw, 0, NULL, 0 ) ) ) { \
                                __done = true; __cont = true;

/** Default behaviour */
#define defaults    } if ( !__done || __cont ) {

/** Close the switchs */
#define switchs_end } while ( 0 ); regfree(&__regex); }

#endif // __SWITCHS_H__

And this is how you use it:

switchs(argv[1]) {
    cases("foo")
    cases("bar")
        printf("foo or bar (case sensitive)\n");
        break;

    icases("pi")
        printf("pi or Pi or pI or PI (case insensitive)\n");
        break;

    cases_re("^D.*",0)
        printf("Something that start with D (case sensitive)\n");
        break;

    cases_re("^E.*",REG_ICASE)
        printf("Something that start with E (case insensitive)\n");
        break;

    cases("1")
        printf("1\n");
        // break omitted on purpose

    cases("2")
        printf("2 (or 1)\n");
        break;

    defaults
        printf("No match\n");
        break;
} switchs_end;

private fun openOtherApp() {
        val sendIntent = packageManager.getLaunchIntentForPackage("org.mab.dhyanaqrscanner")
        startActivity(sendIntent)
        finishAffinity()
    }

If you need to retrieve more columns other than columns which are in group by then you can consider below query. Check it once whether it is performing well or not.

SELECT 
a.[CUSTOMER ID], 
a.[NAME], 
(select SUM(b.[AMOUNT]) from INV_DATA b
where b.[CUSTOMER ID] = a.[CUSTOMER ID]
GROUP BY b.[CUSTOMER ID]) AS [TOTAL AMOUNT]
FROM RES_DATA a

I've briefly covered a simple way to do this with Google Spreadsheets (importHTML) and in Python (Pandas read_html and to_csv) as well as an example Python script in my SO answer here: https://stackoverflow.com/a/28083469/1588795.

Here's in javascript: (For example, the future date is New Year's Day)

DEMO (updates every second)

var dateFuture = new Date(new Date().getFullYear() +1, 0, 1);
var dateNow = new Date();

var seconds = Math.floor((dateFuture - (dateNow))/1000);
var minutes = Math.floor(seconds/60);
var hours = Math.floor(minutes/60);
var days = Math.floor(hours/24);

hours = hours-(days*24);
minutes = minutes-(days*24*60)-(hours*60);
seconds = seconds-(days*24*60*60)-(hours*60*60)-(minutes*60);

(Additional step from solution above for if you are missing the AutoReconnect or Offline registry value)

For Visual Studio 2015, Version 14

1. Turn off all VS instances
2. HKEY_CURRENT_USER\SOFTWARE\Microsoft\VisualStudio\14.0\TeamFoundation\Instances{YourServerName}\Collections{TheCollectionName} (To get to this directory on Windows, hit the Windows + R key and search for "regedit")
3. Set both the Offline and AutoReconnect values to 0.
4. If you are missing one of those attributes (in my case I was missing AutoReconnect), right click and and create a new DWORD(32-bit) value with the desired missing name, AutoReconnect or Offline.
5. Again, make sure both values are set to zero.
6. Restart your solution

Use utf8_encode()

Man page can be found here http://php.net/manual/en/function.utf8-encode.php

Also read this article from Joel on Software. It provides an excellent explanation if what Unicode is and how it works. http://www.joelonsoftware.com/articles/Unicode.html

Simply you can use this snippet:

#include <iostream>
#include <string>
#include <array>

using namespace std;

int main()
{

  array<int,3> values;
  cout << "No. elements in valuea array: " << values.size() << " elements." << endl;
  cout << "sizeof(myints): " << sizeof(values) << endl;

}

and here is the reference : http://www.cplusplus.com/reference/array/array/size/

I'm going to offer up a way to return a boolean based on passing an argument of a reflection Kinds to a local type receiver (because I couldn't find anything like this).

First, we declare our anonymous type of type reflect.Value:

type AnonymousType reflect.Value

Then we add a builder for our local type AnonymousType which can take in any potential type (as an interface):

func ToAnonymousType(obj interface{}) AnonymousType {
    return AnonymousType(reflect.ValueOf(obj))
}

Then we add a function for our AnonymousType struct which asserts against a reflect.Kind:

func (a AnonymousType) IsA(typeToAssert reflect.Kind) bool {
    return typeToAssert == reflect.Value(a).Kind()
}

This allows us to call the following:

var f float64 = 3.4

anon := ToAnonymousType(f)

if anon.IsA(reflect.String) {
    fmt.Println("Its A String!")
} else if anon.IsA(reflect.Float32) {
    fmt.Println("Its A Float32!")
} else if anon.IsA(reflect.Float64) {
    fmt.Println("Its A Float64!")
} else {
    fmt.Println("Failed")
}

Can see a longer, working version here:https://play.golang.org/p/EIAp0z62B7

Another option, just for the heck of it would be:

if ( $('#myFav > *').length > 0 ) {
     // do something
}

May actually be the fastest since it strictly uses the Sizzle engine and not necessarily any jQuery, as it were. Could be wrong though. Nevertheless, it works.

SELECT CONVERT(Datetime, '2011-09-28 18:01:00', 120) -- to convert it to Datetime

SELECT CONVERT( VARCHAR(30), @date ,105) -- italian format [28-09-2011 18:01:00]
+ ' ' + SELECT CONVERT( VARCHAR(30), @date ,108 ) -- full date [with time/minutes/sec]

Try this one:

function show_sub(cat) {
    var parent = cat,
    sub = parent.getElementsByClassName('sub');
    if (sub[0].style.display == 'inline'){
        sub[0].style.display = 'none';
    }
    else {
        sub[0].style.display = 'inline';
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this);
};?

and use this for IE6 & 7

if (typeof document.getElementsByClassName!='function') {
    document.getElementsByClassName = function() {
        var elms = document.getElementsByTagName('*');
        var ei = new Array();
        for (i=0;i<elms.length;i++) {
            if (elms[i].getAttribute('class')) {
               ecl = elms[i].getAttribute('class').split(' ');
                for (j=0;j<ecl.length;j++) {
                    if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
                        ei.push(elms[i]);
                    }
                }
            } else if (elms[i].className) {
                ecl = elms[i].className.split(' ');
                for (j=0;j<ecl.length;j++) {
                    if (ecl[j].toLowerCase() == arguments[0].toLowerCase()) {
                        ei.push(elms[i]);
                    }
                }
            }
        }
        return ei;
    }
}

Consider this snippet of code. Modify as you see fit, or to fit your requirements. You'll need to have Imports statements for System.IO and System.Data.OleDb.

Dim fi As New FileInfo("c:\foo.csv")
Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=Text;Data Source=" & fi.DirectoryName

Dim conn As New OleDbConnection(connectionString)
conn.Open()

'the SELECT statement is important here, 
'and requires some formatting to pull dates and deal with headers with spaces.
Dim cmdSelect As New OleDbCommand("SELECT Foo, Bar, FORMAT(""SomeDate"",'YYYY/MM/DD') AS SomeDate, ""SOME MULTI WORD COL"", FROM " & fi.Name, conn)

Dim adapter1 As New OleDbDataAdapter
adapter1.SelectCommand = cmdSelect

Dim ds As New DataSet
adapter1.Fill(ds, "DATA")

myDataGridView.DataSource = ds.Tables(0).DefaultView 
myDataGridView.DataBind
conn.Close()

You can get a View's coordinates using getLocationOnScreen() or getLocationInWindow()

Afterwards, x and y should be the top-left corner of the view. If your root layout is smaller than the screen (like in a Dialog), using getLocationInWindow will be relative to its container, not the entire screen.

Java Solution

int[] point = new int[2];
view.getLocationOnScreen(point); // or getLocationInWindow(point)
int x = point[0];
int y = point[1];

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post(() -> {
    // Values should no longer be 0
    int[] point = new int[2];
    view.getLocationOnScreen(point); // or getLocationInWindow(point)
    int x = point[0];
    int y = point[1];
});

~~

Kotlin Solution

val point = IntArray(2)
view.getLocationOnScreen(point) // or getLocationInWindow(point)
val (x, y) = point

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post {
    // Values should no longer be 0
    val point = IntArray(2)
    view.getLocationOnScreen(point) // or getLocationInWindow(point)
    val (x, y) = point
}

I recommend creating an extension function for handling this:

// To use, call:
val (x, y) = view.screenLocation

val View.screenLocation get(): IntArray {
    val point = IntArray(2)
    getLocationOnScreen(point)
    return point
}

And if you require reliability, also add:

view.screenLocationSafe { x, y -> Log.d("", "Use $x and $y here") }

fun View.screenLocationSafe(callback: (Int, Int) -> Unit) {
    post {
        val (x, y) = screenLocation
        callback(x, y)
    }
}

I wrote the following to print a list of results to standard out based on available charsets. Note that it also tells you what line fails from a 0 based line number in case you are troubleshooting what character is causing issues.

public static void testCharset(String fileName) {
    SortedMap<String, Charset> charsets = Charset.availableCharsets();
    for (String k : charsets.keySet()) {
        int line = 0;
        boolean success = true;
        try (BufferedReader b = Files.newBufferedReader(Paths.get(fileName),charsets.get(k))) {
            while (b.ready()) {
                b.readLine();
                line++;
            }
        } catch (IOException e) {
            success = false;
            System.out.println(k+" failed on line "+line);
        }
        if (success) 
            System.out.println("*************************  Successs "+k);
    }
}

There are two types of links:

symbolic links: Refer to a symbolic path indicating the abstract location of another file

hard links: Refer to the specific location of physical data.

In your case symlinks:

ln -s source target

you can refer to http://man7.org/linux/man-pages/man7/symlink.7.html

you can create too hard links

A hard link to a file is indistinguishable from the original directory entry; any changes to a file are effectively independent of the name used to reference the file. Hard links may not normally refer to directories and may not span file systems.

ln source link

I know that two threads can not enter in Synchronize block at the same time

Two thread cannot enter a synchronized block on the same object twice. This means that two threads can enter the same block on different objects. This confusion can lead to code like this.

private Integer i = 0;

synchronized(i) {
   i++;
}

This will not behave as expected as it could be locking on a different object each time.

if this is true than How this atomic.incrementAndGet() works without Synchronize ?? and is thread safe ??

yes. It doesn't use locking to achieve thread safety.

If you want to know how they work in more detail, you can read the code for them.

And what is difference between internal reading and writing to Volatile Variable / Atomic Variable ??

Atomic class uses volatile fields. There is no difference in the field. The difference is the operations performed. The Atomic classes use CompareAndSwap or CAS operations.

i read in some article that thread has local copy of variables what is that ??

I can only assume that it referring to the fact that each CPU has its own cached view of memory which can be different from every other CPU. To ensure that your CPU has a consistent view of data, you need to use thread safety techniques.

This is only an issue when memory is shared at least one thread updates it.

Another option is to not read things in character by character -- read the entire file into memory. This is useful if you need to look at the characters more than once. One trivial way to do that is:

  /** Read the contents of a file into a string buffer      */
    public static void readFile(File file, StringBuffer buf)
        throws IOException
    {
    FileReader fr = null;
    try {
      fr = new FileReader(file);
      BufferedReader br = new BufferedReader(fr);
      char[] cbuf = new char[(int) file.length()];
      br.read(cbuf);  
      buf.append(cbuf);
      br.close();
    }
    finally {
      if (fr != null) {
        fr.close();
      }
    }
}

By using the -Xmx command line parameter when you invoke java.

See http://download.oracle.com/javase/6/docs/technotes/tools/windows/java.html

Itertools has a function just for that:

import itertools
it = itertools.repeat(e,n)

Of course itertools gives you a iterator instead of a list. [e] * n gives you a list, but, depending on what you will do with those sequences, the itertools variant can be much more efficient.

Yes it is possible. I have been doing that all the while.

dynamic Obj = JsonConvert.DeserializeObject(<your json string>);

It is a bit trickier for non native type. Suppose inside your Obj, there is a ClassA, and ClassB objects. They are all converted to JObject. What you need to do is:

ClassA ObjA = Obj.ObjA.ToObject<ClassA>();
ClassB ObjB = Obj.ObjB.ToObject<ClassB>();

Are you using C# 3.0? You can use object initializers like so:

static MyStruct[] myArray = 
            new MyStruct[]{
                new MyStruct() { id = 1, label = "1" },
                new MyStruct() { id = 2, label = "2" },
                new MyStruct() { id = 3, label = "3" }
            };

There must be some syntax error. Copy/paste this code and see if it works:

<?php
    $link = mysql_connect('localhost', 'root', '');
    if (!$link) {
        die('Could not connect:' . mysql_error());
    }
    echo 'Connected successfully';
    ?

I had the same error message. It turns out I was using the msql_connect() function instead of mysql_connect().

Flex

In case that you want to display in your <div> some kind of popUp message on screen center - then you don't need to read size of <div> but you can use flex

.box {
  width: 50px;
  height: 20px;
  background: red;
}

.container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
  width: 100vw;
  position: fixed; /* remove this in case there is no content under div (and remember to set body margins to 0)*/
}

<div class="container">
  <div class="box">My div</div>
</div>

Xenph Yan's answer was far cleaner than mine but here is mine all the same.

DECLARE @startStr AS Varchar (20)
SET @startStr = 'tableName'

DECLARE @startStrLen AS int
SELECT @startStrLen = LEN(@startStr)

SELECT 'DROP TABLE ' + name FROM sysobjects
WHERE type = 'U' AND LEFT(name, @startStrLen) = @startStr

Just change tableName to the characters that you want to search with.

Solution:

Use pattern modifier sU will get the desired matching in PHP.

example:

preg_match('/(.*)/sU',$content,$match);

If boolean() is not available (the tool I'm using does not) one way to achieve it is:

//SELECT[@id='xpto']/OPTION[not(not(@selected))]

In this case, within the /OPTION, one of the options is the selected one. The "selected" does not have a value... it just exists, while the other OPTION do not have "selected". This achieves the objective.

Your cells object is not fully qualified. You need to add a DOT before the cells object. For example

With Worksheets("Cable Cards")
    .Range(.Cells(RangeStartRow, RangeStartColumn), _
           .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

Similarly, fully qualify all your Cells object.

Working with position:absolute; along with flex:

Position the flex item with position: relative. Then inside of it, add another <div> element with:

position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;

This extends the element to the boundaries of its relative-positioned parent, but does not allow to extend it. Inside, overflow: auto; will then work as expected.

@Michael Borgwardt's answer actually does not work correctly in Android. Rounding errors exist. Example 19th to 21st May says 1 day because it casts 1.99 to 1. Use round before casting to int.

Fix

int diffInDays = (int)Math.round(( (newerDate.getTime() - olderDate.getTime()) 
                 / (1000 * 60 * 60 * 24) ))

Note that this works with UTC dates, so the difference may be a day off if you look at local dates. And getting it to work correctly with local dates requires a completely different approach due to daylight savings time.

If none of the above works, you might be dealing with a vfat filesystem. Use "df" to check.

See http://www.charlesmerriam.com/blog/2009/12/operation-not-permitted-and-the-fat-32-system/ for more details.

It seems you don't even have to specify the compression any more. The following snippet loads the data from filename.zip into df.

import pandas as pd
df = pd.read_csv('filename.zip')

(Of course you will need to specify separator, header, etc. if they are different from the defaults.)

By default, IUSR account is used for anonymous user.

All you need to do is:

IIS -> Authentication --> Set Anonymous Authentication to Application Pool Identity.

Problem solved :)

new allocates an amount of memory needed to store the object/array that you request. In this case n numbers of int.

The pointer will then store the address to this block of memory.

But be careful, this allocated block of memory will not be freed until you tell it so by writing

delete [] array;

If you look at the values returned by setInterval() they are usually single digits, so you can usually disable all such interrupts with a single line of code:

for (var j = 0 ; j < 256 ; ++j) clearInterval(j)

DEMO

There's a really cool function called document.elementFromPoint which does what it sounds like.

What we need is to find the x and y coords of the mouse and then call it using those values:

var x = event.clientX, y = event.clientY,
    elementMouseIsOver = document.elementFromPoint(x, y);

document.elementFromPoint

jQuery event object

instead of using jQuery.inArray() you can also use includes method for int array :

var array1 = [1, 2, 3];

console.log(array1.includes(2));
// expected output: true

var pets = ['cat', 'dog', 'bat'];

console.log(pets.includes('cat'));
// expected output: true

console.log(pets.includes('at'));
// expected output: false

For Guzzle <= 4:

It's a raw post request so putting the JSON in the body solved the problem

$request = $this->client->post(
    $url,
    [
        'content-type' => 'application/json'
    ],
);
$request->setBody($data); #set body!
$response = $request->send();

If it's a value you'd like to have for every request & template, using a context processor is more appropriate.

Here's how:

1. Make a context_processors.py file in your app directory. Let's say I want to have the ADMIN_PREFIX_VALUE value in every context:

   from django.conf import settings # import the settings file
   
   def admin_media(request):
       # return the value you want as a dictionnary. you may add multiple values in there.
       return {'ADMIN_MEDIA_URL': settings.ADMIN_MEDIA_PREFIX}
   

2. add your context processor to your settings.py file:

   TEMPLATES = [{
       # whatever comes before
       'OPTIONS': {
           'context_processors': [
               # whatever comes before
               "your_app.context_processors.admin_media",
           ],
       }
   }]
   

3. Use RequestContext in your view to add your context processors in your template. The render shortcut does this automatically:

   from django.shortcuts import render
   
   def my_view(request):
       return render(request, "index.html")
   

4. and finally, in your template:

   ...
   <a href="{{ ADMIN_MEDIA_URL }}">path to admin media</a>
   ...
   

SELECT to_char(emp_login_date,'DD-MON-YYYY HH24:MI:SS'),A.* 
FROM emp_log A
WHERE emp_login_date BETWEEN to_date(to_char('21-MAY-2015 11:50:14'),'DD-MON-YYYY HH24:MI:SS')
AND
to_date(to_char('22-MAY-2015 17:56:52'),'DD-MON-YYYY HH24:MI:SS') 
ORDER BY emp_login_date

Prepend the url prefix git+ (See VCS Support):

pip install git+https://github.com/tangentlabs/django-oscar-paypal.git@issue/34/oscar-0.6

And specify the branch name without the leading /.

By default, docker container will exit immediately if you do not have any task running on the container.

To keep the container running in the background, try to run it with --detach (or -d) argument.

For examples:

docker pull debian

docker run -t -d --name my_debian debian
e7672d54b0c2

docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
e7672d54b0c2        debian              "bash"              3 minutes ago       Up 3 minutes                            my_debian

#now you can execute command on the container
docker exec -it my_debian bash
root@e7672d54b0c2:/# 

If you are using Android Studio 3.2 & above,then issue will be solved by adding google() & jcenter() to build.gradle of the project:

repositories {
        google()
        jcenter()
}

The simplest answer is:

On whichever method you declare @Transactional the boundary of transaction starts and boundary ends when method completes.

If you are using JPA call then all commits are with in this transaction boundary.

Lets say you are saving entity1, entity2 and entity3. Now while saving entity3 an exception occur, then as enitiy1 and entity2 comes in same transaction so entity1 and entity2 will be rollback with entity3.

Transaction :

1. entity1.save
2. entity2.save
3. entity3.save

Any exception will result in rollback of all JPA transactions with DB.Internally JPA transaction are used by Spring.

Why can't it be the onResume() is invoked after onRestart() and onCreate() methods just excluding onStart()? What is its purpose?

OK, as my first answer was pretty long I won't extend it further so let's try this...

public DriveToWorkActivity extends Activity
    implements onReachedGroceryStoreListener {
}

public GroceryStoreActivity extends Activity {}

PLEASE NOTE: I've deliberately left out the calls to things like super.onCreate(...) etc. This is pseudo-code so give me some artistic licence here. ;)

The methods for DriveToWorkActivity follow...

protected void onCreate(...) {
    openGarageDoor();
    unlockCarAndGetIn();
    closeCarDoorAndPutOnSeatBelt();
    putKeyInIgnition();
}

protected void onStart() {
    startEngine();
    changeRadioStation();
    switchOnLightsIfNeeded();
    switchOnWipersIfNeeded();
}

protected void onResume() {
    applyFootbrake();
    releaseHandbrake();
    putCarInGear();
    drive();
}

protected void onPause() {
    putCarInNeutral();
    applyHandbrake();
}

protected void onStop() {
    switchEveryThingOff();
    turnOffEngine();
    removeSeatBeltAndGetOutOfCar();
    lockCar();
}

protected void onDestroy() {
    enterOfficeBuilding();
}

protected void onReachedGroceryStore(...) {
    Intent i = new Intent(ACTION_GET_GROCERIES, ...,  this, GroceryStoreActivity.class);
}

protected void onRestart() {
    unlockCarAndGetIn();
    closeDoorAndPutOnSeatBelt();
    putKeyInIgnition();
}

OK, so it's another long one (sorry folks). But here's my explanation...

onResume() is when I start driving and onPause() is when I come to a temporary stop. So I drive then reach a red light so I pause...the light goes green and I resume. Another red light and I pause, then green so I resume. The onPause() -> onResume() -> onPause() -> onResume() loop is a tight one and occurs many times through my journey.

The loop from being stopped back through a restart (preparing to carry on my journey) to starting again is perhaps less common. In one case, I spot the Grocery Store and the GroceryStoreActivity is started (forcing my DriveToWorkActivity to the point of onStop()). When I return from the store, I go through onRestart() and onStart() then resume my journey.

I could put the code that's in onStart() into both onCreate() and onRestart() and not bother to override onStart() at all but the more that needs to be done between onCreate() -> onResume() and onRestart() -> onResume(), the more I'm duplicating things.

So, to requote once more...

Why can't it be the onResume() is invoked after onRestart() and onCreate() methods just excluding onStart()?

If you don't override onStart() then this is effectively what happens. Although the onStart() method of Activity will be called implicitly, the effect in your code is effectively onCreate() -> onResume() or onRestart() -> onResume().

I'd like to add complementary information: In postman app you may use the "request" object to see your subsituted input data. (refer to https://www.getpostman.com/docs/postman/scripts/postman_sandbox in paragraph "Request/response related properties", ie.

console.log("header : " + request.headers["Content-Type"]);
console.log("body : " + request.data);
console.log("url : " + request.url);

I didn't test for header substitution but it works for url and body.

config - class which will read from property files

cache - caching mechanism class files

constants - constant defined class

controller - controller class

exception - exception class

model - pojos classes will be present

security - security classes

service - Impl classes

util - utility classes

validation - validators classes

bootloader - main class

Off the top of my head:

1. They enforce tight-coupling. If your singleton resides on a different assembly than its user, the using assembly cannot ever function without the assembly containing the singleton.
2. They allow for circular dependencies, e.g., Assembly A can have a singleton with a dependency on Assembly B, and Assembly B can use Assembly A's singleton. All without breaking the compiler.

• First create HashMap.

  HashMap> mapList = new HashMap>();

• Get value from HashMap against your input key.

  ArrayList arrayList = mapList.get(key);

• Add value to arraylist.

  arrayList.add(addvalue);

• Then again put arraylist against that key value. mapList.put(key,arrayList);

It will work.....

using Object.keys instead.

const data = {
  a: "first",
  b: "second",
};

const values = Object.keys(data).map(key => data[key]);

const commaJoinedValues = values.join(",");
console.log(commaJoinedValues);

The expression between the <%= %> is evaluated before the c:if tag is evaluated. So, supposing that |request.isUserInRole| returns |true|, your example would be evaluated to this first:

<c:if test="true">
    <li>user</li>
</c:if>

and then the c:if tag would be executed.

Thank for the answers,

The border is removed for Internet Explorer, but this there for Firefox.

So, I added this class to the img:

.clearBorder{border:none;}

And it worked!

At VS2012 V11, if I use "-Reinstall" at the end of the line it doesn't work.

So I simply used:

Update-Package -ProjectName 'NAME_OF_THE_PROJECT'

A line feed means moving one line forward. The code is \n.
A carriage return means moving the cursor to the beginning of the line. The code is \r.

Windows editors often still use the combination of both as \r\n in text files. Unix uses mostly only the \n.

The separation comes from typewriter times, when you turned the wheel to move the paper to change the line and moved the carriage to restart typing on the beginning of a line. This was two steps.

In some cases data was not encoded into JSON format, so you need to encode it first e.g

 json_encode($data);

Later you will use json Parse in your JS, like

JSON.parse(data);

There seems to be another (rather hacky) way to reuse the router-outlet in one template. This answer is intendend for informational purposes only and the techniques used here should probably not be used in production.

https://stackblitz.com/edit/router-outlet-twice-with-events

The router-outlet is wrapped by an ng-template. The template is updated by listening to events of the router. On every event the template is swapped and re-swapped with an empty placeholder. Without this "swapping" the template would not be updated.

This most definetly is not a recommended approach though, since the whole swapping of two templates seems a bit hacky.

in the controller:

  ngOnInit() {
    this.router.events.subscribe((routerEvent: Event) => {
      console.log(routerEvent);
      this.myTemplateRef = this.trigger;
      setTimeout(() => {
        this.myTemplateRef = this.template;
      }, 0);
    });
  }

in the template:

<div class="would-be-visible-on-mobile-only">
  This would be the mobile-layout with a router-outlet (inside a template): 
  <br>
  <ng-container *ngTemplateOutlet="myTemplateRef"></ng-container>
</div>

<hr>

<div class="would-be-visible-on-desktop-only">
  This would be the desktop-layout with a router-outlet (inside a template): 
  <br>
  <ng-container *ngTemplateOutlet="myTemplateRef"></ng-container>
</div>

<ng-template #template>
    <br>
    This is my counter: {{counter}}
    inside the template, the router-outlet should follow
    <router-outlet>
    </router-outlet>
</ng-template>

<ng-template #trigger>
  template to trigger changes...
</ng-template>

The type module also exists if you are checking more than ints and strings. http://docs.python.org/library/types.html

FILE *f = fopen("file.txt", "w");
if (f == NULL)
{
    printf("Error opening file!\n");
    exit(1);
}

/* print some text */
const char *text = "Write this to the file";
fprintf(f, "Some text: %s\n", text);

/* print integers and floats */
int i = 1;
float py = 3.1415927;
fprintf(f, "Integer: %d, float: %f\n", i, py);

/* printing single chatacters */
char c = 'A';
fprintf(f, "A character: %c\n", c);

fclose(f);

And yet another approach using the decorator pattern and PHPs magic getter & setters:

// A simple StdClass object    
$stdclass = new StdClass();
$stdclass->foo = 'bar';

// Decorator base class to inherit from
class Decorator {

    protected $object = NULL;

    public function __construct($object)
    {
       $this->object = $object;  
    }

    public function __get($property_name)
    {
        return $this->object->$property_name;   
    }

    public function __set($property_name, $value)
    {
        $this->object->$property_name = $value;   
    }
}

class MyClass extends Decorator {}

$myclass = new MyClass($stdclass)

// Use the decorated object in any type-hinted function/method
function test(MyClass $object) {
    echo $object->foo . '<br>';
    $object->foo = 'baz';
    echo $object->foo;   
}

test($myclass);

Unless you are forced to use C, you should never use malloc. Always use new.

If you need a big chunk of data just do something like:

char *pBuffer = new char[1024];

Be careful though this is not correct:

//This is incorrect - may delete only one element, may corrupt the heap, or worse...
delete pBuffer;

Instead you should do this when deleting an array of data:

//This deletes all items in the array
delete[] pBuffer;

The new keyword is the C++ way of doing it, and it will ensure that your type will have its constructor called. The new keyword is also more type-safe whereas malloc is not type-safe at all.

The only way I could think that would be beneficial to use malloc would be if you needed to change the size of your buffer of data. The new keyword does not have an analogous way like realloc. The realloc function might be able to extend the size of a chunk of memory for you more efficiently.

It is worth mentioning that you cannot mix new/free and malloc/delete.

Note: Some answers in this question are invalid.

int* p_scalar = new int(5);  // Does not create 5 elements, but initializes to 5
int* p_array  = new int[5];  // Creates 5 elements

Clang now supports dynamic overflow checks for both signed and unsigned integers. See the -fsanitize=integer switch. For now, it is the only C++ compiler with fully supported dynamic overflow checking for debug purposes.

Below methods are very Easy to understand and you can implement existing forms in minutes

With Jquery,

$(document).ready(function() {
  $('#check-all').click(function(){
    $("input:checkbox").attr('checked', true);
  });
  $('#uncheck-all').click(function(){
    $("input:checkbox").attr('checked', false);
  });
});

in HTML form put below buttons

<a id="check-all" href="javascript:void(0);">check all</a>
<a id="uncheck-all" href="javascript:void(0);">uncheck all</a> 

With just using javascript,

<script type="text/javascript">
function checkAll(formname, checktoggle)
{
  var checkboxes = new Array(); 
  checkboxes = document[formname].getElementsByTagName('input');

  for (var i=0; i<checkboxes.length; i++)  {
    if (checkboxes[i].type == 'checkbox')   {
      checkboxes[i].checked = checktoggle;
    }
  }
}
</script>

in HTML form put below buttons

<button onclick="javascript:checkAll('form3', true);" href="javascript:void();">check all</button>

<button onclick="javascript:checkAll('form3', false);" href="javascript:void();">uncheck all</button>

Altova XmlSpy does this well - you can find an overview here

You can also extract the event code from the HTML, like this :

<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" />
<label for="check_all_1">Select All</label>

<script>
function selectAll(frmElement, chkElement) {
    // ...
}
document.getElementById("check_all_1").onclick = function() {
    selectAll(document.wizard_form, this);
}
</script>

In this case, you might get some differences. Consider a line like:

"foo\tbar "

In this case, if you strip, then you'll get {"foo":"bar"} as the dictionary entry. If you don't strip, you'll get {"foo":"bar "} (note the extra space at the end)

Note that if you use line.split() instead of line.split('\t'), you'll split on every whitespace character and the "striping" will be done during splitting automatically. In other words:

line.strip().split()

is always identical to:

line.split()

but:

line.strip().split(delimiter)

Is not necessarily equivalent to:

line.split(delimiter)

Since the question is not directly mentioning Visual Studio, I will post how to do this in JetBrains Rider.

From context menu

1. Right-click your project
2. Go to edit
3. Edit '{project-name.csproj}'

With shortcut

1. Select project
2. Press F4

This solution worked for MacOS Sierra, and running MySQL version 8.0.11. Please make sure driver you have added in your build path - "add external jar" should match up with SQL version.

String url = "jdbc:mysql://localhost:3306/syscharacterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true";

Edit ~/.bash_profile, add this to it.

PATH=$PATH:$HOME/anaconda/bin

then run

source ~/.bash_profile

Hope can help you.
