One more alternative is json-simple which can be found in Maven Central:

(JSONObject)JSONValue.parse(someString); //JSONObject is actually a Map.

The artifact is 24kbytes, doesn't have other runtime dependencies.

Use Microsoft Message Analyzer v1.4

Navigate to ProcessId from the field chooser.

Etw
-> EtwProviderMsg
--> EventRecord
---> Header
----> ProcessId

Right click and Add as Column

You can query the USER_TAB_COLUMNS table for table column metadata.

SELECT table_name, column_name, data_type, data_length
FROM USER_TAB_COLUMNS
WHERE table_name = 'MYTABLE'

No need to use BufferedImage, as you already have the image file in a byte array

    byte dearr[] = Base64.decodeBase64(crntImage);
    FileOutputStream fos = new FileOutputStream(new File("c:/decode/abc.bmp")); 
    fos.write(dearr); 
    fos.close();

Sometimes even the simplest things can make a difference. One of these simple items that should be part of every stored procedure is SET NOCOUNT ON. This one line of code, put at the top of a stored procedure turns off the messages that SQL Server sends back to the client after each T-SQL statement is executed. This is performed for all SELECT, INSERT, UPDATE, and DELETE statements. Having this information is handy when you run a T-SQL statement in a query window, but when stored procedures are run there is no need for this information to be passed back to the client.

By removing this extra overhead from the network it can greatly improve overall performance for your database and application.

If you still need to get the number of rows affected by the T-SQL statement that is executing you can still use the @@ROWCOUNT option. By issuing a SET NOCOUNT ON this function (@@ROWCOUNT) still works and can still be used in your stored procedures to identify how many rows were affected by the statement.

You could use the concrete class LinkedList instead of the general interface List. Then you have a descendingIterator for iterating with the reverse direction.

LinkedList<String > linkedList;
for( Iterator<String > it = linkedList.descendingIterator(); it.hasNext(); ) {
    String text = it.next();
}

Don't know why there is no descendingIterator with ArrayList...

I got this same error working in Eclipse with Maven with the additional information

schema_reference.4: Failed to read schema document 'https://maven.apache.org/xsd/maven-4.0.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

This was after copying in a new controller and it's interface from a Thymeleaf example. Honestly, no matter how careful I am I still am at a loss to understand how one is expected to figure this out. On a (lucky) guess I right clicked the project, clicked Maven and Update Project which cleared up the issue.

An XSD is a formal contract that specifies how an XML document can be formed. It is often used to validate an XML document, or to generate code from.

assuming your project is maven based, add it to your POM:

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.26</version>
    </dependency>

Save > Build > and test connection again. It works! Your actual mysql java connector version may vary.

You can find some useful query here:

This is my implementation of Multi-Dimension Array.

In this approach, I am creating a single dimension array

I have added a prototype function multi to Array object, Which can be used to create any dimension Array.

I have also added a prototype function index to Array object, Which can be used to get index in linear Array from multi-dimension indexes.

Creating a Array

//Equivalent to arr[I][J][K]..[] in C
var arr = new Array().multi(I,J,K,..);

Accessing array value at any index

//Equivalent in C arr[i][j][k];
var vaue = arr[arr.index(i,j,k)];

Use the reset function, which is available on the form element.

var form = document.getElementById("myForm");
form.reset();

Have you seen this? Sending email using Smtp.mail.microsoftonline.com

Setting the UseDefaultCredentials after setting the Credentials would be resetting your Credentials property.

When you want a relative path from your home directory (on any UNIX) you use this strange syntax:

ssh://[user@]host.xz[:port]/~[user]/path/to/repo

For Example, if the repo is in /home/jack/projects/jillweb on the server jill.com and you are logging in as jack with sshd listening on port 4242:

ssh://[email protected]:4242/~/projects/jillweb

And when logging in as jill (presuming you have file permissions):

ssh://[email protected]:4242/~jack/projects/jillweb

maybe this is what you want

I have made an attempt with illustrative pictures and working code in Java,

Here's from my own code:
Window.setTimeout executes only when browser is idle.
So calling the function recursively (42 times) will take 100ms if there is no activity in the browser and much more if the browser is busy doing something else.

    ExpectedCondition<Boolean> javascriptDone = new ExpectedCondition<Boolean>() {
        public Boolean apply(WebDriver d) {
            try{//window.setTimeout executes only when browser is idle,
                //introduces needed wait time when javascript is running in browser
                return  ((Boolean) ((JavascriptExecutor) d).executeAsyncScript( 

                        " var callback =arguments[arguments.length - 1]; " +
                        " var count=42; " +
                        " setTimeout( collect, 0);" +
                        " function collect() { " +
                            " if(count-->0) { "+
                                " setTimeout( collect, 0); " +
                            " } "+
                            " else {callback(" +
                            "    true" +                            
                            " );}"+                             
                        " } "
                    ));
            }catch (Exception e) {
                return Boolean.FALSE;
            }
        }
    };
    WebDriverWait w = new WebDriverWait(driver,timeOut);  
    w.until(javascriptDone);
    w=null;

As a bonus the counter can be reset on document.readyState or on jQuery Ajax calls or if any jQuery animations are running (only if your app uses jQuery for ajax calls...)
...

" function collect() { " +
                            " if(!((typeof jQuery === 'undefined') || ((jQuery.active === 0) && ($(\":animated\").length === 0))) && (document.readyState === 'complete')){" +
                            "    count=42;" +
                            "    setTimeout( collect, 0); " +
                            " }" +
                            " else if(count-->0) { "+
                                " setTimeout( collect, 0); " +
                            " } "+ 

...

EDIT: I notice executeAsyncScript doesn't work well if a new page loads and the test might stop responding indefinetly, better to use this on instead.

A left rotation operation on an array of size n shifts each of the array's elements unit to the left, check this out!!!!!!

public class Solution {
    private static final Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {
        String[] nd = scanner.nextLine().split(" ");

        int n = Integer.parseInt(nd[0]);  //no. of elements in the array

        int d = Integer.parseInt(nd[1]);  //number of left rotations

        int[] a = new int[n]; 

      for(int i=0;i<n;i++){
          a[i]=scanner.nextInt();
      }

        Solution s= new Solution();     
//number of left rotations
        for(int j=0;j<d;j++){
              s.rotate(a,n);
        }
   //print the shifted array  
        for(int i:a){System.out.print(i+" ");}
    }

//shift each elements to the left by one 
   public static void rotate(int a[],int n){
            int  temp=a[0];
        for(int i=0;i<n;i++){
            if(i<n-1){a[i]=a[i+1];}
            else{a[i]=temp;}
      }}
}

IF they are both UTC date-time values you can do TimeSpan diff = dateTime1 - dateTime2;

Otherwise your chance of getting the correct answer in every single possible case is zero.

Add the following code before you instantiate your web service client:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Or for backward compatibility with TLS 1.1 and prior:

System.Net.ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12; 

If you want to change all columns of a certain type to another type, you can generate queries using a query like this:

select distinct concat('alter table ',
                       table_name,
                       ' modify ',
                       column_name,
                       ' <new datatype> ',
                       if(is_nullable = 'NO', ' NOT ', ''),
                       ' NULL;')
  from information_schema.columns
  where table_schema = '<your database>' 
    and column_type = '<old datatype>';

For instance, if you want to change columns from tinyint(4) to bit(1), run it like this:

select distinct concat('alter table ',
                       table_name,
                       ' modify ',
                       column_name,
                       ' bit(1) ',
                       if(is_nullable = 'NO', ' NOT ', ''),
                       ' NULL;')
  from information_schema.columns
  where table_schema = 'MyDatabase' 
    and column_type = 'tinyint(4)';

and get an output like this:

alter table table1 modify finished bit(1)  NOT  NULL;
alter table table2 modify canItBeTrue bit(1)  NOT  NULL;
alter table table3 modify canBeNull bit(1)  NULL;

!! Does not keep unique constraints, but should be easily fixed with another if-parameter to concat. I'll leave it up to the reader to implement that if needed..

I've installed and use VB6 for legacy projects many times on Windows 7.

What I have done and never came across any issues, is to install VB6, ignore the errors and then proceed to install the latest service pack, currently SP6.

Download here: http://www.microsoft.com/en-us/download/details.aspx?id=5721

Bonus: Also once you install it and realize that scrolling doesn't work, use the below: http://www.joebott.com/vb6scrollwheel.htm

Switch to the branch from which you created the pull request:

$ git checkout pull-request-branch

Overwrite the modified file(s) with the file in another branch, let's consider it's master:

git checkout origin/master -- src/main/java/HelloWorld.java

Commit and push it to the remote:

git commit -m "Removed a modified file from pull request"
git push origin pull-request-branch

This is my working variant for Laravel 7

  ->select('id','name')
  ->whereNotIn('id', DB::table('curses')->where('id_user', $id)->pluck('id_user')->toArray())
  ->get();

updated for swift 1.2

You can use dateutil.parser.parse (install with python -m pip install python-dateutil) to parse strings into datetime objects.

dateutil.parser.parse will attempt to guess the format of your string, if you know the exact format in advance then you can use datetime.strptime which you supply a format string to (see Brent Washburne's answer).

from dateutil.parser import parse

a = "2012-10-09T19:00:55Z"

b = parse(a)

print(b.weekday())
# 1 (equal to a Tuesday)

Just add these to libraries to your project:

<link href="https://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.min.css" rel="stylesheet"></link>
<script src="https://code.jquery.com/ui/1.10.2/jquery-ui.min.js"></script>

Save and reload. You're good to go.

I solved a problem like yours by this way:

foreach(array_keys($idarr) as $i) {
 echo "Student ID: ".$idarr[$i]."<br />";
 echo "Present: ".$presentarr[$i]."<br />";
 echo "Reason: ".$reasonarr[$i]."<br />";
 echo "Mark: ".$markarr[$i]."<br />";
}

I hope this work for you.

After checking the error log, I found this:

120309 17:42:49 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data

120309 17:42:50 mysqld_safe mysqld from pid file /usr/local/mysql/data/lu1s.local.pid ended

And to solve it, I gave ownership rights to the entire mysql folder:

cd /usr/local
sudo chown mysql mysql
sudo chown mysql mysql-5.5.21-osx10.6-x86_64
sudo chown _mysql mysql
sudo chown _mysql mysql-5.5.21-osx10.6-x86_64

Then (you can do it command-line too), I applied the permissions (once I gave that ownership to _mysql and mysql users) to all enclosed folders from within the "get info" menu of the folder at /usr/local/mysql-5.5.21-osx10.6-x86_64 . You don't need to tho that to the alias since it's only an alias.

The name of the folder depends of the installation version of mysql that you have.

If you want to retrieve the length (and possibly all other metadata) from your media file with ffmpeg by using a python script you could try this:

import subprocess
import json

input_file  = "< path to your input file here >"

metadata = subprocess.check_output(f"ffprobe -i {input_file} -v quiet -print_format json -show_format -hide_banner".split(" "))

metadata = json.loads(metadata)
print(f"Length of file is: {float(metadata['format']['duration'])}")
print(metadata)

Output:

Length of file is: 7579.977143

Depends on implementation but I would use

(?i)G[a-b].

VARIATIONS:

(?i) case-insensitive mode ON    
(?-i) case-insensitive mode OFF

Modern regex flavors allow you to apply modifiers to only part of the regular expression. If you insert the modifier (?im) in the middle of the regex then the modifier only applies to the part of the regex to the right of the modifier. With these flavors, you can turn off modes by preceding them with a minus sign (?-i).

Description is from the page: https://www.regular-expressions.info/modifiers.html

Here is some production code that sends the file to an ftp (may be a good solution for you):

// This is the entire file that was uploaded to a temp location.
$localFile = $_FILES[$fileKey]['tmp_name']; 

$fp = fopen($localFile, 'r');

// Connecting to website.
$ch = curl_init();

curl_setopt($ch, CURLOPT_USERPWD, "[email protected]:password");
curl_setopt($ch, CURLOPT_URL, 'ftp://@ftp.website.net/audio/' . $strFileName);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400); // 1 Day Timeout
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'CURL_callback');
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localFile));
curl_exec ($ch);

if (curl_errno($ch)) {

    $msg = curl_error($ch);
}
else {

    $msg = 'File uploaded successfully.';
}

curl_close ($ch);

$return = array('msg' => $msg);

echo json_encode($return);

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

I just done it this way ...

$('body').css('overflow', 'hidden');

But when the scroller dissapeared it moved everything right 20px, so i added

$('body').css('margin-right', '20px');

straight after it.

Works for me.

I've managed to achieve it with minimal effort (just as simple as with ASP.NET Core).

For that I use OWIN Startup.cs file and Microsoft.Owin.Security.Jwt library.

In order for the app to hit Startup.cs we need to amend Web.config:

<configuration>
  <appSettings>
    <add key="owin:AutomaticAppStartup" value="true" />
    ...

Here's how Startup.cs should look:

using MyApp.Helpers;
using Microsoft.IdentityModel.Tokens;
using Microsoft.Owin;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Jwt;
using Owin;

[assembly: OwinStartup(typeof(MyApp.App_Start.Startup))]

namespace MyApp.App_Start
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.UseJwtBearerAuthentication(
                new JwtBearerAuthenticationOptions
                {
                    AuthenticationMode = AuthenticationMode.Active,
                    TokenValidationParameters = new TokenValidationParameters()
                    {
                        ValidAudience = ConfigHelper.GetAudience(),
                        ValidIssuer = ConfigHelper.GetIssuer(),
                        IssuerSigningKey = ConfigHelper.GetSymmetricSecurityKey(),
                        ValidateLifetime = true,
                        ValidateIssuerSigningKey = true
                    }
                });
        }
    }
}

Many of you guys use ASP.NET Core nowadays, so as you can see it doesn't differ a lot from what we have there.

It really got me perplexed first, I was trying to implement custom providers, etc. But I didn't expect it to be so simple. OWIN just rocks!

Just one thing to mention - after I enabled OWIN Startup NSWag library stopped working for me (e.g. some of you might want to auto-generate typescript HTTP proxies for Angular app).

The solution was also very simple - I replaced NSWag with Swashbuckle and didn't have any further issues.

Ok, now sharing ConfigHelper code:

public class ConfigHelper
{
    public static string GetIssuer()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Issuer"];
        return result;
    }

    public static string GetAudience()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Audience"];
        return result;
    }

    public static SigningCredentials GetSigningCredentials()
    {
        var result = new SigningCredentials(GetSymmetricSecurityKey(), SecurityAlgorithms.HmacSha256);
        return result;
    }

    public static string GetSecurityKey()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["SecurityKey"];
        return result;
    }

    public static byte[] GetSymmetricSecurityKeyAsBytes()
    {
        var issuerSigningKey = GetSecurityKey();
        byte[] data = Encoding.UTF8.GetBytes(issuerSigningKey);
        return data;
    }

    public static SymmetricSecurityKey GetSymmetricSecurityKey()
    {
        byte[] data = GetSymmetricSecurityKeyAsBytes();
        var result = new SymmetricSecurityKey(data);
        return result;
    }

    public static string GetCorsOrigins()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["CorsOrigins"];
        return result;
    }
}

Another important aspect - I sent JWT Token via Authorization header, so typescript code looks for me as follows:

(the code below is generated by NSWag)

@Injectable()
export class TeamsServiceProxy {
    private http: HttpClient;
    private baseUrl: string;
    protected jsonParseReviver: ((key: string, value: any) => any) | undefined = undefined;

    constructor(@Inject(HttpClient) http: HttpClient, @Optional() @Inject(API_BASE_URL) baseUrl?: string) {
        this.http = http;
        this.baseUrl = baseUrl ? baseUrl : "https://localhost:44384";
    }

    add(input: TeamDto | null): Observable<boolean> {
        let url_ = this.baseUrl + "/api/Teams/Add";
        url_ = url_.replace(/[?&]$/, "");

        const content_ = JSON.stringify(input);

        let options_ : any = {
            body: content_,
            observe: "response",
            responseType: "blob",
            headers: new HttpHeaders({
                "Content-Type": "application/json", 
                "Accept": "application/json",
                "Authorization": "Bearer " + localStorage.getItem('token')
            })
        };

See headers part - "Authorization": "Bearer " + localStorage.getItem('token')

Whatever happens outside the Scope of Angular, Angular will never know that.

Digest cycle put the changes from the model -> controller and then from controller -> model.

If you need to see the latest Model, you need to trigger the digest cycle

But there is a chance of a digest cycle in progress, so we need to check and init the cycle.

Preferably, always perform a safe apply.

       $scope.safeApply = function(fn) {
            if (this.$root) {
                var phase = this.$root.$$phase;
                if (phase == '$apply' || phase == '$digest') {
                    if (fn && (typeof (fn) === 'function')) {
                        fn();
                    }
                } else {
                    this.$apply(fn);
                }
            }
        };


      $scope.safeApply(function(){
          // your function here.
      });

You need to do this in transaction to ensure two simultaneous clients won't insert same fieldValue twice:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
BEGIN TRANSACTION
    DECLARE @id AS INT
    SELECT @id = tableId FROM table WHERE fieldValue=@newValue
    IF @id IS NULL
    BEGIN
       INSERT INTO table (fieldValue) VALUES (@newValue)
       SELECT @id = SCOPE_IDENTITY()
    END
    SELECT @id
COMMIT TRANSACTION

you can also use Double-checked locking to reduce locking overhead

DECLARE @id AS INT
SELECT @id = tableID FROM table (NOLOCK) WHERE fieldValue=@newValue
IF @id IS NULL
BEGIN
    SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
    BEGIN TRANSACTION
        SELECT @id = tableID FROM table WHERE fieldValue=@newValue
        IF @id IS NULL
        BEGIN
           INSERT INTO table (fieldValue) VALUES (@newValue)
           SELECT @id = SCOPE_IDENTITY()
        END
    COMMIT TRANSACTION
END
SELECT @id

As for why ISOLATION LEVEL SERIALIZABLE is necessary, when you are inside a serializable transaction, the first SELECT that hits the table creates a range lock covering the place where the record should be, so nobody else can insert the same record until this transaction ends.

Without ISOLATION LEVEL SERIALIZABLE, the default isolation level (READ COMMITTED) would not lock the table at read time, so between SELECT and UPDATE, somebody would still be able to insert. Transactions with READ COMMITTED isolation level do not cause SELECT to lock. Transactions with REPEATABLE READS lock the record (if found) but not the gap.

A jQuery solution

HTML

<select id="foo">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
</select>

Javascript

// remove child "option" element with a "value" attribute equal to "2"
$("#foo > option[value='2']").remove();

// remove all child "option" elements
$("#foo > option").remove();

References:

Attribute Equals Selector [name=value]

Selects elements that have the specified attribute with a value exactly equal to a certain value.

Child Selector (“parent > child”)

Selects all direct child elements specified by "child" of elements specified by "parent"

.remove()

Similar to .empty(), the .remove() method takes elements out of the DOM. We use .remove() when we want to remove the element itself, as well as everything inside it. In addition to the elements themselves, all bound events and jQuery data associated with the elements are removed.

If you use %pylab inline you can (on a new line) insert the following command:

%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)

This will set all figures in your document (unless otherwise specified) to be of the size (10, 6), where the first entry is the width and the second is the height.

See this SO post for more details. https://stackoverflow.com/a/17231361/1419668

Here is an example of accessing the ith index of a std::vector using an std::iterator within a loop which does not require incrementing two iterators.

std::vector<std::string> strs = {"sigma" "alpha", "beta", "rho", "nova"};
int nth = 2;
std::vector<std::string>::iterator it;
for(it = strs.begin(); it != strs.end(); it++) {
    int ith = it - strs.begin();
    if(ith == nth) {
        printf("Iterator within  a for-loop: strs[%d] = %s\n", ith, (*it).c_str());
    }
}

Without a for-loop

it = strs.begin() + nth;
printf("Iterator without a for-loop: strs[%d] = %s\n", nth, (*it).c_str());

and using at method:

printf("Using at position: strs[%d] = %s\n", nth, strs.at(nth).c_str());

Other answers have given clear enough examples of a record referencing another record in the same table.

There are even valid use cases for a record referencing itself in the same table. For example, a point of sale system accepting many tenders may need to know which tender to use for change when the payment is not the exact value of the sale. For many tenders that's the same tender, for others that's domestic cash, for yet other tenders, no form of change is allowed.

All this can be pretty elegantly represented with a single tender attribute which is a foreign key referencing the primary key of the same table, and whose values sometimes match the respective primary key of same record. In this example, the absence of value (also known as NULL value) might be needed to represent an unrelated meaning: this tender can only be used at its full value.

Popular relational database management systems support this use case smoothly.

Take-aways:

1. When inserting a record, the foreign key reference is verified to be present after the insert, rather than before the insert.

2. When inserting multiple records with a single statement, the order in which the records are inserted matters. The constraints are checked for each record separately.

3. Certain other data patterns, such as those involving circular dependences on record level going through two or more tables, cannot be purely inserted at all, or at least not with all the foreign keys enabled, and they have to be established using a combination of inserts and updates (if they are truly necessary).

Jupyter has its own PATH variable, JUPYTER_PATH.

Adding this line to the .bashrc file worked for me:

export JUPYTER_PATH=<directory_for_your_module>:$JUPYTER_PATH

Adding this to manifest solved my problem

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Try adding this:

$mail->SMTPAuth   = true;
$mail->SMTPSecure = "tls";

By looking at your debug logs, you can notice that the failing PhpMailer log shows this:

(..snip..)
SMTP -> ERROR: AUTH not accepted from server: 250 orion.bommtempo.net.br Hello admin-teste.bommtempo.com.br [200.155.129.6]
(..snip..)
503 AUTH command used when not advertised
(..snip..)

While your successful PEAR log shows this:

DEBUG: Send: STARTTLS
DEBUG: Recv: 220 TLS go ahead

My guess is that explicitly asking PHPMailer to use TLS will put it on the right track.
Also, make sure you're using the latest versin of PHPMailer.

No, you would have to use a for-loop for that.

for (int i = 0; i < lst1.Count; i++)
{
    //lst1[i]...
    //lst2[i]...
}

You can't do something like

foreach (var objCurrent1 int lst1, var objCurrent2 in lst2)
{
    //...
}

The two methods of adding do generate slightly different byte code:

  17: iconst_2
  18: iload         4
  20: iload         4
  22: imul
  23: imul
  24: iadd

For 2 * (i * i) vs:

  17: iconst_2
  18: iload         4
  20: imul
  21: iload         4
  23: imul
  24: iadd

For 2 * i * i.

And when using a JMH benchmark like this:

@Warmup(iterations = 5, batchSize = 1)
@Measurement(iterations = 5, batchSize = 1)
@Fork(1)
@BenchmarkMode(Mode.AverageTime)
@OutputTimeUnit(TimeUnit.MILLISECONDS)
@State(Scope.Benchmark)
public class MyBenchmark {

    @Benchmark
    public int noBrackets() {
        int n = 0;
        for (int i = 0; i < 1000000000; i++) {
            n += 2 * i * i;
        }
        return n;
    }

    @Benchmark
    public int brackets() {
        int n = 0;
        for (int i = 0; i < 1000000000; i++) {
            n += 2 * (i * i);
        }
        return n;
    }

}

The difference is clear:

# VM version: JDK 11, Java HotSpot(TM) 64-Bit Server VM, 11+28

What you observe is correct, and not just an anomaly of your benchmarking style (i.e. no warmup, see How do I write a correct micro-benchmark in Java?)

You see that the results are much closer, which makes sense, since Graal is an overall better performing, more modern, compiler.

So this is really just up to how well the JIT compiler is able to optimize a particular piece of code, and doesn't necessarily have a logical reason to it.

Not sure why this worked for me while nothing else did but just in case anyone else is still looking...

In between head tags:

<script>
     function myFunction() {
           script code
     }
</script>

Then for the < a > tag:

<a href='' onclick='myFunction()' > Call Function </a>

$('element[id$=txtTitle]')

It's not strictly necessary to quote the text fragment you are matching against

Normalization is your best friend in comment/rank/vote system. Learn it. A lot of sites are now moving to PDO ... learn that as well.

there are no right , right-er, or wrong (well there is) ways of doing it, you need to know the basic concepts and take them from there. IF you don't feel like learning, then perhaps invest in a framework like cakephp or zend framework, or a ready made system like wordpress or joomla.

I'd also recommend the book wicked cool php scripts as it has a comment system example in it.

Another thing to check is that some routers have issues bridging the requests when both 2.4G and 5G are enabled and the devices are on different frequencies. Trying disabling one of the frequencies so both devices are connected to the same interface.

If you don't care about the data, you can drop database first and then recreate it:

DROP DATABASE IF EXISTS dbname;
CREATE DATABASE dbname;

I believe it's in C:\Windows\System32\WindowsPowershell\v1.0\. In order to confuse the innocent, MS kept it in a directory labeled "v1.0". Running this on Windows 7 and checking the version number via $Host.Version (Determine installed PowerShell version) shows it's 2.0.

Another option is type $PSVersionTable at the command prompt. If you are running v2.0, the output will be:

Name                           Value
----                           -----
CLRVersion                     2.0.50727.4927

PSCompatibleVersions           {1.0, 2.0}
SerializationVersion           1.1.0.1
PSRemotingProtocolVersion      2.1

If you're running version 1.0, the variable doesn't exist and there will be no output.

If you add your site to "Local Intranet" in

use

head -n 1 filename | od -c 

to figure WHAT is the offending character. then use

tr -d '\n' <filename

I found this solution in this article

.parent-element {
  -webkit-transform-style: preserve-3d;
  -moz-transform-style: preserve-3d;
  transform-style: preserve-3d;
}

.element {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

It work like a charm if the height of element is not fixed.

I just wanted to share how I did this find/replace thing with sql database, because I needed to replace links from Chrome's sessionbuddy db file.

• So I exported sql database file as .txt file by using SQLite Database Browser 2.0 b1
• Find/replace in notepad++
• Imported the .txt file back on SQLite Database Browser 2.0 b1

Actually this is possible without position absolute and specifying any height. All You need to do, is use display: grid on parent element and put descendants, into the same row and column.

Please check example below, based on Your HTML. I added only <span> and some colors, so You can see the result.

You can also easily change z-index each of descendant elements, to manipulate its visibility (which one should be on top).

.container_row{_x000D_
  display: grid;_x000D_
}_x000D_
_x000D_
.layer1, .layer2{_x000D_
  grid-column: 1;_x000D_
  grid-row: 1;_x000D_
}_x000D_
_x000D_
.layer1 span{_x000D_
  color: #fff;_x000D_
  background: #000cf6;_x000D_
}_x000D_
_x000D_
.layer2{_x000D_
  background: rgba(255, 0, 0, 0.4);_x000D_
}

<div class="container_row">_x000D_
    <div class="layer1">_x000D_
        <span>Lorem ipsum...<br>Test test</span>_x000D_
    </div>_x000D_
    <div class="layer2">_x000D_
        More lorem ipsum..._x000D_
    </div>_x000D_
</div>_x000D_
<div class="container_row">_x000D_
    ...same HTML as above. This one should never overlap the .container_row above._x000D_
</div>

You could also use BufferedReader:

import java.io.*;

public class TestApplication {
   public static void main (String[] args) {
      System.out.print("Enter a password: ");
      BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
      String password = null;
      try {
         password = br.readLine();
      } catch (IOException e) {
         System.out.println("IO error trying to read your password!");
         System.exit(1);
      }
      System.out.println("Successfully read your password.");
   }
}

A method group is the name for a set of methods (that might be just one) - i.e. in theory the ToString method may have multiple overloads (plus any extension methods): ToString(), ToString(string format), etc - hence ToString by itself is a "method group".

It can usually convert a method group to a (typed) delegate by using overload resolution - but not to a string etc; it doesn't make sense.

Once you add parentheses, again; overload resolution kicks in and you have unambiguously identified a method call.

You're inserting values for OperationId that is an identity column.

You can turn on identity insert on the table like this so that you can specify your own identity values.

SET IDENTITY_INSERT Table1 ON

INSERT INTO Table1
/*Note the column list is REQUIRED here, not optional*/
            (OperationID,
             OpDescription,
             FilterID)
VALUES      (20,
             'Hierachy Update',
             1)

SET IDENTITY_INSERT Table1 OFF 

Since you are using an INNER JOIN you can just put the conditions in the WHERE clause, like this:

SELECT 
    p1.kArtikel, 
    p1.cName, 
    p1.cKurzBeschreibung, 
    p1.dLetzteAktualisierung, 
    p1.dErstellt, 
    p1.cSeo,
    p2.kartikelpict,
    p2.nNr,
    p2.cPfad  
FROM 
    tartikel AS p1 INNER JOIN tartikelpict AS p2 
    ON p1.kArtikel = p2.kArtikel
WHERE
  DATE(dErstellt) > (NOW() - INTERVAL 7 DAY)
  AND p2.nNr = 1
ORDER BY 
  p1.kArtikel DESC
LIMIT
    100;

...We don't have a newer version of MySQL yet, so I was able to do this (works only on UNIX):

 host=maindb

 echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked

The above will query for all locked sessions, and return the information and SQL that is involved.

...So- assuming you wanted to query for sessions that were sleeping:

  host=maindb

  echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep

Or, assuming you needed to provide additional connection parameters for MySQL:

  host=maindb

  user=me

  password=mycoolpassword 

  echo "show full processlist\G" | mysql -h$host -u$user -p$password | grep -B 6 -A 1 Locked

With a couple of tweaks, I'm sure a shell script could be easily created to query the processlist the way you want it.

Just to offer you a different angle -

I find it's not a good idea to maintain public variables between function calls. Any variables you need to use should be stored in Subs and Functions and passed as parameters. Once the code is done running, you shouldn't expect the VBA Project to maintain the values of any variables.

The reason for this is that there is just a huge slew of things that can inadvertently reset the VBA Project while using the workbook. When this happens, any public variables get reset to 0.

If you need a value to be stored outside of your subs and functions, I highly recommend using a hidden worksheet with named ranges for any information that needs to persist.

Call

perror("execl");

in case of error.

Sample:

if(read(fd, buf, 1)==-1) {
    perror("read");
}

The manpages of errno(3) and perror(3) are interesting, too...

Here is the example in which you can easily find the way to use Post,GET method and use the same way to add other curd operations as well..

#libraries to include

import os
from flask import request, jsonify
from app import app, mongo
import logger
ROOT_PATH = os.environ.get('ROOT_PATH')<br>
@app.route('/get/questions/', methods=['GET', 'POST','DELETE', 'PATCH'])
    def question():
    # request.args is to get urls arguments 


    if request.method == 'GET':
        start = request.args.get('start', default=0, type=int)
        limit_url = request.args.get('limit', default=20, type=int)
        questions = mongo.db.questions.find().limit(limit_url).skip(start);
        data = [doc for doc in questions]
        return jsonify(isError= False,
                    message= "Success",
                    statusCode= 200,
                    data= data), 200

# request.form to get form parameter

    if request.method == 'POST':
        average_time = request.form.get('average_time')
        choices = request.form.get('choices')
        created_by = request.form.get('created_by')
        difficulty_level = request.form.get('difficulty_level')
        question = request.form.get('question')
        topics = request.form.get('topics')

    ##Do something like insert in DB or Render somewhere etc. it's up to you....... :)

Another way to do this in Notepad++ is all in the Find/Replace dialog and with regex:

• Ctrl + h to bring up the find replace dialog.

• In the Find what: text box include your regex: .*help.*\r?\n (where the \r is optional in case the file doesn't have Windows line endings).

• Leave the Replace with: text box empty.

• Make sure the Regular expression radio button in the Search Mode area is selected. Then click Replace All and voila! All lines containing your search term help have been removed.

I have tried some of the answers and found them not working.

This works for me:

from sklearn.metrics import classification_report

print(classification_report(y_test, predicted)) 

if your intention is send the full array from the html to the controller, can use this:

from the blade.php:

 <input type="hidden" name="quotation" value="{{ json_encode($quotation,TRUE)}}"> 

in controller

    public function Get(Request $req) {

    $quotation = array('quotation' => json_decode($req->quotation));

    //or

    return view('quotation')->with('quotation',json_decode($req->quotation))


}

Escaping a double quote can absolutely be necessary in sed: for instance, if you are using double quotes in the entire sed expression (as you need to do when you want to use a shell variable).

Here's an example that touches on escaping in sed but also captures some other quoting issues in bash:

# cat inventory
PURCHASED="2014-09-01"
SITE="Atlanta"
LOCATION="Room 154"

Let's say you wanted to change the room using a sed script that you can use over and over, so you variablize the input as follows:

# i="Room 101" (these quotes are there so the variable can contains spaces)

This script will add the whole line if it isn't there, or it will simply replace (using sed) the line that is there with the text plus the value of $i.

if grep -q LOCATION inventory; then 
## The sed expression is double quoted to allow for variable expansion; 
## the literal quotes are both escaped with \ 
    sed -i "/^LOCATION/c\LOCATION=\"$i\"" inventory
## Note the three layers of quotes to get echo to expand the variable
## AND insert the literal quotes
else 
    echo LOCATION='"'$i'"' >> inventory
fi

P.S. I wrote out the script above on multiple lines to make the comments parsable but I use it as a one-liner on the command line that looks like this:

i="your location"; if grep -q LOCATION inventory; then sed -i "/^LOCATION/c\LOCATION=\"$i\"" inventory; else echo LOCATION='"'$i'"' >> inventory; fi

Few things to fix here:

1. No parenthesis in class declaration
2. Make the "correct" property as public
3. And then do the selection

Your code will look something like this

List<Answer> answers = new List<Answer>();
/* test
answers.Add(new Answer() { correct = false });
answers.Add(new Answer() { correct = true });
answers.Add(new Answer() { correct = false });
*/
Answer answer = answers.Single(a => a.correct == true);

and the class

class Answer
{
   public bool correct;
}

Another, pretty simple approach is to call list function:

list(df['one'][2])
# output:
['This is very long string very long string very long string veryvery long string']

No worth to mention, that is not good to convent to list the whole columns, but for a simple line - why not

"currently yes but i think it might cause problems at peak moments" I can confirm, that I had a problem where I got timeouts because of peak requests. After I set the max pool size, the application ran without any problems. IIS 7.5 / ASP.Net

To call the function you have to add ()

{this.renderIcon()}   

.communicate() writes input (there is no input in this case so it just closes subprocess' stdin to indicate to the subprocess that there is no more input), reads all output, and waits for the subprocess to exit.

The exception EOFError is raised in the child process by raw_input() (it expected data but got EOF (no data)).

p.stdout.read() hangs forever because it tries to read all output from the child at the same time as the child waits for input (raw_input()) that causes a deadlock.

To avoid the deadlock you need to read/write asynchronously (e.g., by using threads or select) or to know exactly when and how much to read/write, for example:

from subprocess import PIPE, Popen

p = Popen(["python", "-u", "1st.py"], stdin=PIPE, stdout=PIPE, bufsize=1)
print p.stdout.readline(), # read the first line
for i in range(10): # repeat several times to show that it works
    print >>p.stdin, i # write input
    p.stdin.flush() # not necessary in this case
    print p.stdout.readline(), # read output

print p.communicate("n\n")[0], # signal the child to exit,
                               # read the rest of the output, 
                               # wait for the child to exit

Note: it is a very fragile code if read/write are not in sync; it deadlocks.

Beware of block-buffering issue (here it is solved by using "-u" flag that turns off buffering for stdin, stdout in the child).

bufsize=1 makes the pipes line-buffered on the parent side.

It happened with me when I changed the instance type of my AWS server.

#2002 Cannot log in to the MySQL server can also occur when the mysqld service is not started.

So first of all you need to execute :

$ sudo service mysqld restart

This will give you :

$ sudo service mysqld restart
Stopping mysqld:                                           [  OK  ]
Starting mysqld:                                           [  OK  ]

After that the error will not come.

P.S. On EC2 instances, one should also change the host from localhost to 127.0.0.1 as mentioned in the top answer.

One more Windows recipe: use system-wide environment variable NUMBER_OF_PROCESSORS:

printf("%d\n", atoi(getenv("NUMBER_OF_PROCESSORS")));

Follow @abs solution

If you still continue to get the error even after setting the JAVA_HOME variable Copy the studio folder to your C drive and then run the studio.exe or studio64.exe depending upon your java versio

It worked for me to add a class name to the input and then apply CSS rules to that:

<input type="text" name="product" class="product" />

<style>
input[value=""].product {
    display: none;
}
</style>

> df2 <- data.frame(sapply(df1, function(x) as.numeric(as.character(x))))
> df2
     a b
1 0.01 2
2 0.02 4
3 0.03 5
4 0.04 7
> sapply(df2, class)
        a         b 
"numeric" "numeric" 

Exec can be messy on windows. There is a more "nodie" solution. Fundamentally, you have a recursive call to see if a directory exists and dive into the child (if it does exist) or create it. Here is a function that will create the children and call a function when finished:

fs = require('fs');
makedirs = function(path, func) {
 var pth = path.replace(/['\\]+/g, '/');
 var els = pth.split('/');
 var all = "";
 (function insertOne() {
   var el = els.splice(0, 1)[0];
   if (!fs.existsSync(all + el)) {
    fs.mkdirSync(all + el);
   }
   all += el + "/";
   if (els.length == 0) {
    func();
   } else {
     insertOne();
   }
   })();

}

Add ID attributes with same values as name attributes and then you can do this:

$('#first_name').change(function () {
  $('#firstname').val($(this).val());
});

I know that the title of the thread refers to the use of a regex, but just as the Zawinski quote says, I really think that avoiding regexes is best here. I'd recommend this function instead:

function get_youtube_id($url)
{
    if (strpos( $url,"v=") !== false)
    {
        return substr($url, strpos($url, "v=") + 2, 11);
    }
    elseif(strpos( $url,"embed/") !== false)
    {
        return substr($url, strpos($url, "embed/") + 6, 11);
    }

}

I recommend this because the ID of YouTube videos is always the same, independent from the style of the URL, e.g.

• http://www.youtube.com/watch?v=t_uW44Bsezg
• http://www.youtube.com/watch?feature=endscreen&v=Id3xG4xnOfA&NR=1
• `And Other Ulr Form In Which The Word "embed/" Is Placed Before The Id ... !!

and that might be the case for embedded and iframe-ed stuff.

if you implement with dialog edittext. use like this:. its same with use to other edittext.

dialog.getInputEditText().addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence charSequence, int start, int before, int count) {
    }

    @Override
    public void onTextChanged(CharSequence charSequence, int start, int before, int count) {
        if (start<2){
                dialog.getActionButton(DialogAction.POSITIVE).setEnabled(false);
            }else{
                double size =  Double.parseDouble(charSequence.toString());
                if (size > 0.000001 && size < 0.999999){
                    dialog.getActionButton(DialogAction.POSITIVE).setEnabled(true);
                }else{
                    ToastHelper.show(HistoryActivity.this, "Size must between 0.1 - 0.9");
                    dialog.getActionButton(DialogAction.POSITIVE).setEnabled(false);
                }

            }
    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
});

Scripting languages are programming languages that don't require an explicit compilation step.

For example, in the normal case, you have to compile a C program before you can run it. But in the normal case, you don't have to compile a JavaScript program before you run it. So JavaScript is sometimes called a "scripting" language.

This line is getting more and more blurry since compilation can be so fast with modern hardware and modern compilation techniques. For instance, V8, the JavaScript engine in Google Chrome and used a lot outside of the browser as well, actually compiles the JavaScript code on the fly into machine code, rather than interpreting it. (In fact, V8's an optimizing two-phase compiler.)

Also note that whether a language is a "scripting" language or not can be more about the environment than the language. There's no reason you can't write a C interpreter and use it as a scripting language (and people have). There's also no reason you can't compile JavaScript to machine code and store that in an executable file (and people have). The language Ruby is a good example of this: The original implementation was entirely interpreted (a "scripting" language), but there are now multiple compilers for it.

Some examples of "scripting" languages (e.g., languages that are traditionally used without an explicit compilation step):

• Lua
• JavaScript
• VBScript and VBA
• Perl

And a small smattering of ones traditionally used with an explicit compilation step:

• C
• C++
• D
• Java (but note that Java is compiled to bytecode, which is then interpreted and/or recompiled at runtime)
• Pascal

...and then you have things like Python that sit in both camps: Python is widely used without a compilation step, but the main implementation (CPython) does that by compiling to bytecode on-the-fly and then running the bytecode in a VM, and it can write that bytecode out to files (.pyc, .pyo) for use without recompiling.

That's just a very few, if you do some research you can find a lot more.

Try this from cmd line as Administrator

optional part, if you need to use a proxy:

set HTTP_PROXY=http://login:password@your-proxy-host:your-proxy-port
set HTTPS_PROXY=http://login:password@your-proxy-host:your-proxy-port

npm install -g --production windows-build-tools

No need for Visual Studio. This has what you need.

Check what $TERM gives: mine is xterm-color and ls -alG then does colorised output.

This can also cause some trouble: Accidentally one of my layouts was parked in my tablet resources folder, so I got this error only with phone layout. The phone layout simply had no suitable layout file.

I worked again after moving the layout file in the correct standard folder and a following project rebuild.

    printf("%8d\n",1);
    printf("%8d\n",10);
    printf("%8d\n",100);
    printf("%8d\n",1000);

Just Define following lines at top of your Database SQL file.

SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";

It is working for me.

You can do like this. Open a ts file ad there make an interface with inputs you want and in the page you want to show under export class write

readonly yourinterface = yourinterface
readonly level: number[] = [];

and in your template do like this *ngFor="let yourtype of yourinterface"

You can't launch arbitrary commands, but if your users are willing to go through some extra setup, you can use custom protocols.

E.g. you have the users set things up so that some-app:// links start "SomeApp", and then in my-awesome-extension you open a tab pointing to some-app://some-data-the-app-wants, and you're good to go!

Several of the answers on this page are 'single use' fixes to the described problem. Meaning, the next time you open a document with vim, the previous tab settings will return.

If anyone is interested in permanently changing the tab settings:

• find/open your .vimrc - instructions here

• add the following lines: (more info here)

   set tabstop=4
   set shiftwidth=4
   set expandtab
  

• then save file and test

You can also use .map() as:

var list=[];

response.data.message.map(function(value, key) {
     list.push(value);
   });

In my case it was installing into an already existing directory. When you choose a directory for the installation. The programm won't allow you to type in a non-existing directory. So choose the path, get back to the main window and type the new folder name where you want install the SDK, probably feature.

model.predict() expects the first parameter to be a numpy array. You supply a list, which does not have the shape attribute a numpy array has.

Otherwise your code looks fine, except that you are doing nothing with the prediction. Make sure you store it in a variable, for example like this:

prediction = model.predict(np.array(tk.texts_to_sequences(text)))
print(prediction)

If you are working with a FileInfo object, then there is an easy way to extract a string representation of the directory's full path via the DirectoryName property.

Description of the FileInfo.DirectoryName Property via MSDN:

Gets a string representing the directory's full path.

Sample usage:

string filename = @"C:\MyDirectory\MyFile.bat";
FileInfo fileInfo = new FileInfo(filename);
string directoryFullPath = fileInfo.DirectoryName; // contains "C:\MyDirectory"

Link to the MSDN documentation.

You don't import scripts in Python you import modules. Some python modules are also scripts that you can run directly (they do some useful work at a module-level).

In general it is preferable to use absolute imports rather than relative imports.

toplevel_package/
+-- __init__.py
+-- moduleA.py
+-- subpackage
    +-- __init__.py
    +-- moduleB.py

In moduleB:

from toplevel_package import moduleA

If you'd like to run moduleB.py as a script then make sure that parent directory for toplevel_package is in your sys.path.

You can't run PHP in .html files because the server does not recognize that as a valid PHP extension unless you tell it to. To do this you need to create a .htaccess file in your root web directory and add this line to it:

AddType application/x-httpd-php .htm .html

This will tell Apache to process files with a .htm or .html file extension as PHP files.

If the other solutions here do not work, make sure you are not in 'offline' mode. If enabled, android will not download the required files and you will get this error.

I had the same problem and I found out that if you add the URL param ?v=3 you won't get the warning message anymore:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3"></script>

Reproduction online

As pointed out in the comments by @Zia Ul Rehman Mughal

Turns out specifying this means you are referring to old frozen version 3.0 not the latest version. Frozen old versions are not updated with bug fixes or anything. But this is good to mention though. https://developers.google.com/maps/documentation/javascript/versions#the-frozen-version

Update 07-Jun-2016

This solution doesn't work anymore.

You may emulate a map with a closure:

package main

import (
    "fmt"
)

// http://stackoverflow.com/a/27457144/10278

func romanNumeralDict() func(int) string {
    // innerMap is captured in the closure returned below
    innerMap := map[int]string{
        1000: "M",
        900:  "CM",
        500:  "D",
        400:  "CD",
        100:  "C",
        90:   "XC",
        50:   "L",
        40:   "XL",
        10:   "X",
        9:    "IX",
        5:    "V",
        4:    "IV",
        1:    "I",
    }

    return func(key int) string {
        return innerMap[key]
    }
}

func main() {
    fmt.Println(romanNumeralDict()(10))
    fmt.Println(romanNumeralDict()(100))

    dict := romanNumeralDict()
    fmt.Println(dict(400))
}

Try it on the Go playground

There are quite significant differences when it comes to working with branches (especially short-term ones).

It is explained in this article (BranchingExplained) which compares Mercurial with Git.

I'd like to make some changes: In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
   int int_a = * ( (int*) a );
   int int_b = * ( (int*) b );

   // an easy expression for comparing
   return (int_a > int_b) - (int_a < int_b);
}

qsort( a, 6, sizeof(int), compare )

ogdate is itself a string, why are you trying to access it's value property that it doesn't have ?

console.log(og_date.split('-'));

pyarrow compatibility across versions

Overall move has been to pyarrow/feather (deprecation warnings from pandas/msgpack). However I have a challenge with pyarrow with transient in specification Data serialized with pyarrow 0.15.1 cannot be deserialized with 0.16.0 ARROW-7961. I'm using serialization to use redis so have to use a binary encoding.

I've retested various options (using jupyter notebook)

import sys, pickle, zlib, warnings, io
class foocls:
    def pyarrow(out): return pa.serialize(out).to_buffer().to_pybytes()
    def msgpack(out): return out.to_msgpack()
    def pickle(out): return pickle.dumps(out)
    def feather(out): return out.to_feather(io.BytesIO())
    def parquet(out): return out.to_parquet(io.BytesIO())

warnings.filterwarnings("ignore")
for c in foocls.__dict__.values():
    sbreak = True
    try:
        c(out)
        print(c.__name__, "before serialization", sys.getsizeof(out))
        print(c.__name__, sys.getsizeof(c(out)))
        %timeit -n 50 c(out)
        print(c.__name__, "zlib", sys.getsizeof(zlib.compress(c(out))))
        %timeit -n 50 zlib.compress(c(out))
    except TypeError as e:
        if "not callable" in str(e): sbreak = False
        else: raise
    except (ValueError) as e: print(c.__name__, "ERROR", e)
    finally: 
        if sbreak: print("=+=" * 30)        
warnings.filterwarnings("default")

With following results for my data frame (in out jupyter variable)

feather and parquet do not work for my data frame. I'm going to continue using pyarrow. However I will supplement with pickle (no compression). When writing to cache store pyarrow and pickle serialised forms. When reading from cache fallback to pickle if pyarrow deserialisation fails.

EDIT: I'm getting a lot of downvotes on this recently...so I thought I'd just add a note that this answer was written before the question underwent it's most recent edit, where returning null was highlighted as an option...which seems very acceptable. Some of my answer was addressed to concerns like that of Edwardo, in the comments, who seemed to be advocating returning a 0. This is the case I was railing against.

ANSWER: I think there's an underlying issue here, which is that division by 0 is not legal. It's an indication that something is fundementally wrong. If you're dividing by zero, you're trying to do something that doesn't make sense mathematically, so no numeric answer you can get will be valid. (Use of null in this case is reasonable, as it is not a value that will be used in later mathematical calculations).

So Edwardo asks in the comments "what if the user puts in a 0?", and he advocates that it should be okay to get a 0 in return. If the user puts zero in the amount, and you want 0 returned when they do that, then you should put in code at the business rules level to catch that value and return 0...not have some special case where division by 0 = 0.

That's a subtle difference, but it's important...because the next time someone calls your function and expects it to do the right thing, and it does something funky that isn't mathematically correct, but just handles the particular edge case it's got a good chance of biting someone later. You're not really dividing by 0...you're just returning an bad answer to a bad question.

Imagine I'm coding something, and I screw it up. I should be reading in a radiation measurement scaling value, but in a strange edge case I didn't anticipate, I read in 0. I then drop my value into your function...you return me a 0! Hurray, no radiation! Except it's really there and it's just that I was passing in a bad value...but I have no idea. I want division to throw the error because it's the flag that something is wrong.

You can double protect your file removal with NSFileManager.defaultManager().isDeletableFileAtPath(PathName) As of now you MUST use do{}catch{} as the old error methods no longer work. isDeletableFileAtPath() is not a "throws" (i.e. "public func removeItemAtPath(path: String) throws") so it does not need the do...catch

let killFile = NSFileManager.defaultManager()

            if (killFile.isDeletableFileAtPath(PathName)){


                do {
                  try killFile.removeItemAtPath(arrayDictionaryFilePath)
                }
                catch let error as NSError {
                    error.description
                }
            }

Am I doing that right, as far as iterating through the Arraylist goes?

No: by calling iterator twice in each iteration, you're getting new iterators all the time.

The easiest way to write this loop is using the for-each construct:

for (String s : arrayList)
    if (s.equals(value))
        // ...

As for

java.lang.ArrayIndexOutOfBoundsException: -1

You just tried to get element number -1 from an array. Counting starts at zero.

according to this link: http://www.authorcode.com/how-to-check-file-permission-to-write-in-c/

it's easier to use existing class SecurityManager

string FileLocation = @"C:\test.txt";
FileIOPermission writePermission = new FileIOPermission(FileIOPermissionAccess.Write, FileLocation);
if (SecurityManager.IsGranted(writePermission))
{
  // you have permission
}
else
{
 // permission is required!
}

but it seems it's been obsoleted, it is suggested to use PermissionSet instead.

[Obsolete("IsGranted is obsolete and will be removed in a future release of the .NET Framework.  Please use the PermissionSet property of either AppDomain or Assembly instead.")]

It is like

<?php
use yii\helpers\ArrayHelper;
use backend\models\Standard;
?>

<?= Html::activeDropDownList($model, 's_id',
      ArrayHelper::map(Standard::find()->all(), 's_id', 'name')) ?>

ArrayHelper in Yii2 replaces the CHtml list data in Yii 1.1.[Please load array data from your controller]

EDIT

Load data from your controller.

Controller

$items = ArrayHelper::map(Standard::find()->all(), 's_id', 'name');
...
return $this->render('your_view',['model'=>$model, 'items'=>$items]);

In View

<?= Html::activeDropDownList($model, 's_id',$items) ?>

No need to use static in this case as thoroughly explained. You might as well initialise your property without GetItem() method, example of both below:

namespace MyNamespace
{
    using System;

    public class MyType
    {
        public string MyProperty { get; set; } = new string();
        public static string MyStatic { get; set; } = "I'm static";
    }
}

Consuming:

using MyType;

public class Somewhere 
{
    public void Consuming(){

        // through instance of your type
        var myObject = new MyType(); 
        var alpha = myObject.MyProperty;

        // through your type 
        var beta = MyType.MyStatic;
    }
}       

JButton#isEnabled changes the user interactivity of a component, that is, whether a user is able to interact with it (press it) or not.

When a JButton is pressed, it fires a actionPerformed event.

You are receiving Add button is pressed when you press the confirm button because the add button is enabled. As stated, it has nothing to do with the pressed start of the button.

Based on you code, if you tried to check the "pressed" start of the add button within the confirm button's ActionListener it would always be false, as the button will only be in the pressed state while the add button's ActionListeners are being called.

Based on all this information, I would suggest you might want to consider using a JCheckBox which you can then use JCheckBox#isSelected to determine if it has being checked or not.

Take a closer look at How to Use Buttons for more details

$('#someid').attr('disabled', 'true');

Is this what you are looking for.

$("input.address_field").on('click', function(){  
     $(this).css('border', '2px solid red');
});

raw_input is a form of input that takes the argument in the form of a string whereas the input function takes the value depending upon your input. Say, a=input(5) returns a as an integer with value 5 whereas a=raw_input(5) returns a as a string of "5"

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html> 

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

getElementById returns null if there is no such element.

You need to use cat to get the contents of the file named 'DSC_0251.JPG', rather than the filename itself.

test="$(cat DSC_0251.JPG | base64)"

However, base64 can read from the file itself:

test=$( base64 DSC_0251.JPG )

create a class create a object globally and call this

using System.IO;
using System.Reflection;


   public class LogWriter
{
    private string m_exePath = string.Empty;
    public LogWriter(string logMessage)
    {
        LogWrite(logMessage);
    }
    public void LogWrite(string logMessage)
    {
        m_exePath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
        try
        {
            using (StreamWriter w = File.AppendText(m_exePath + "\\" + "log.txt"))
            {
                Log(logMessage, w);
            }
        }
        catch (Exception ex)
        {
        }
    }

    public void Log(string logMessage, TextWriter txtWriter)
    {
        try
        {
            txtWriter.Write("\r\nLog Entry : ");
            txtWriter.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(),
                DateTime.Now.ToLongDateString());
            txtWriter.WriteLine("  :");
            txtWriter.WriteLine("  :{0}", logMessage);
            txtWriter.WriteLine("-------------------------------");
        }
        catch (Exception ex)
        {

You can use Pusher

It's a hosted service that makes it super-easy to add real-time data and functionality to web and mobile applications.
Pusher offers libraries to integrate into all the main runtimes and frameworks.

PHP, Ruby, Python, Java, .NET, Go and Node on the server
JavaScript, Objective-C (iOS) and Java (Android) on the client.

dataGridView1[1,1].Value="tes";

Several ways to do so, here are some possible one-line approaches:

2. Use getch() (need #include <conio.h>).

3. Use getchar() (expected for Enter, need #include <iostream>).

4. Use cin.get() (expected for Enter, need #include <iostream>).

5. Use system("pause") (need #include <iostream>).

   PS: This method will also print Press any key to continue . . . on the screen. (seems perfect choice for you :))

Edit: As discussed here, There is no completely portable solution for this. Question 19.1 of the comp.lang.c FAQ covers this in some depth, with solutions for Windows, Unix-like systems, and even MS-DOS and VMS.

There's a really good paper by Microsoft Research called To Blob or Not To Blob.

Their conclusion after a large number of performance tests and analysis is this:

• if your pictures or document are typically below 256K in size, storing them in a database VARBINARY column is more efficient

• if your pictures or document are typically over 1 MB in size, storing them in the filesystem is more efficient (and with SQL Server 2008's FILESTREAM attribute, they're still under transactional control and part of the database)

• in between those two, it's a bit of a toss-up depending on your use

If you decide to put your pictures into a SQL Server table, I would strongly recommend using a separate table for storing those pictures - do not store the employee photo in the employee table - keep them in a separate table. That way, the Employee table can stay lean and mean and very efficient, assuming you don't always need to select the employee photo, too, as part of your queries.

For filegroups, check out Files and Filegroup Architecture for an intro. Basically, you would either create your database with a separate filegroup for large data structures right from the beginning, or add an additional filegroup later. Let's call it "LARGE_DATA".

Now, whenever you have a new table to create which needs to store VARCHAR(MAX) or VARBINARY(MAX) columns, you can specify this file group for the large data:

 CREATE TABLE dbo.YourTable
     (....... define the fields here ......)
     ON Data                   -- the basic "Data" filegroup for the regular data
     TEXTIMAGE_ON LARGE_DATA   -- the filegroup for large chunks of data

Check out the MSDN intro on filegroups, and play around with it!

The Google collections framework offers a good and elegant way to achieve the null check.

There is a method in a library class like this:

static <T> T checkNotNull(T e) {
   if (e == null) {
      throw new NullPointerException();
   }
   return e;
}

And the usage is (with import static):

...
void foo(int a, Person p) {
   if (checkNotNull(p).getAge() > a) {
      ...
   }
   else {
      ...
   }
}
...

Or in your example:

checkNotNull(someobject).doCalc();

I believe this is the NSDate's selector you're looking for:

- (NSTimeInterval)timeIntervalSince1970

Try this:

       import java.net.HttpURLConnection;

       URL url = new URL("http://www.myurl.com/sample.xml");

       HttpURLConnection huc = (HttpURLConnection) url.openConnection();
       HttpURLConnection.setFollowRedirects(false);
       huc.setConnectTimeout(15 * 1000);
       huc.setRequestMethod("GET");
       huc.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
       huc.connect();
       InputStream input = huc.getInputStream();

OR

       import org.jsoup.nodes.Document;

       Document doc = null;
       try {
           doc = Jsoup.connect("http://www.myurl.com/sample.xml").get();
       } catch (Exception e) {
           //log error
       }

And take look on how to use Jsoup: http://jsoup.org/cookbook/input/load-document-from-url

The VCS files can have its information coded in Quoted printable which is a nightmare. The above solution recommending "VCS to ICS Calendar Converter" is the way to go.

"You should always use GridFS for storing files larger than 16MB" - When should I use GridFS?

MongoDB BSON documents are capped at 16 MB. So if the total size of your array of files is less than that, you may store them directly in your document using the BinData data type.

Videos, images, PDFs, spreadsheets, etc. - it doesn't matter, they are all treated the same. It's up to your application to return an appropriate content type header to display them.

Check out the GridFS documentation for more details.

A class is a reference type. When an object of the class is created, the variable to which the object is assigned holds only a reference to that memory. When the object reference is assigned to a new variable, the new variable refers to the original object. Changes made through one variable are reflected in the other variable because they both refer to the same data. A struct is a value type. When a struct is created, the variable to which the struct is assigned holds the struct's actual data. When the struct is assigned to a new variable, it is copied. The new variable and the original variable therefore contain two separate copies of the same data. Changes made to one copy do not affect the other copy. In general, classes are used to model more complex behavior, or data that is intended to be modified after a class object is created. Structs are best suited for small data structures that contain primarily data that is not intended to be modified after the struct is created.

Classes and Structs (C# Programming Guide)

• Under Server Administration on the Home window select the server instance you want to restore database to (Create New Server Instance if doing it first time).
• Click on Manage Import/Export
• Click on Data Import/Restore on the left side of the screen.
• Select Import from Self-Contained File radio button (right side of screen)
• Select the path of .sql
• Click Start Import button at the right bottom corner of window.

Hope it helps.

---Edited answer---

Regarding selection of the schema. MySQL Workbench (5.2.47 CE Rev1039) does not yet support exporting to the user defined schema. It will create only the schema for which you exported the .sql... In 5.2.47 we see "New" target schema. But it does not work. I use MySQL Administrator (the old pre-Oracle MySQL Admin beauty) for my work for backup/restore. You can still download it from Googled trustable sources (search MySQL Administrator 1.2.17).

I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.

public abstract class ExternalScript extends Script {

    private String source;

    public void setSource(String file) {
        source = file;
    }

    public String getSource() {
        return source;
    }
}

Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:

• If source was protected (so accessible by subclasses) then code gets messy: who's changing the variables? When it's an object it then becomes hard when you need to refactor, whereas a method tends to make this step easier.
• If your getter/setter methods aren't getting and setting, then describe them as something else.

Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.

Agree with all above answers of using MutableList but you can also add/remove from List and get a new list as below.

val newListWithElement = existingList + listOf(element)
val newListMinusElement = existingList - listOf(element)

Or

val newListWithElement = existingList.plus(element)
val newListMinusElement = existingList.minus(element)

.border-blue.background { ... } is for one item with multiple classes.
.border-blue, .background { ... } is for multiple items each with their own class.
.border-blue .background { ... } is for one item where '.background' is the child of '.border-blue'.

See Chris' answer for a more thorough explanation.

Vim mailing list says (re-formatted for better readability):

To change two vertically split windows to horizonally split

Ctrl-w t Ctrl-w K

Horizontally to vertically:

Ctrl-w t Ctrl-w H

Explanations:

Ctrl-w t makes the first (topleft) window current

Ctrl-w K moves the current window to full-width at the very top

Ctrl-w H moves the current window to full-height at far left

Note that the t is lowercase, and the K and H are uppercase.

Also, with only two windows, it seems like you can drop the Ctrl-w t part because if you're already in one of only two windows, what's the point of making it current?

Try using this instead:

var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();

It's bit hard to navigate Google's api but here is the relevant documentation.

One thing I had trouble finding was how to go in the other direction. From coordinates to an address. Here is the code I neded upp using. Please not that I also use jquery.

$.each(results[0].address_components, function(){
    $("#CreateDialog").find('input[name="'+ this.types+'"]').attr('value', this.long_name);
});

What I'm doing is to loop through all the returned address_components and test if their types match any input element names I have in a form. And if they do I set the value of the element to the address_components value.
If you're only interrested in the whole formated address then you can follow Google's example

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

Would suggest NOT using INSERT IGNORE as it ignores ALL errors (ie its a sloppy global ignore). Instead, since in your example tag is the unique key, use:

INSERT INTO table_tags (tag) VALUES ('tag_a'),('tab_b'),('tag_c') ON DUPLICATE KEY UPDATE tag=tag;

on duplicate key produces:

Query OK, 0 rows affected (0.07 sec)

typeperf "\processor(_total)\% processor time"

does work on Win7, you just need to extract the percent value yourself from the last quoted string.

Pandas >= 0.25: Remove Case Distinctions with str.casefold

Starting from v0.25, I recommend using the "vectorized" string method str.casefold if you're dealing with unicode data (it works regardless of string or unicodes):

s = pd.Series(['lower', 'CAPITALS', np.nan, 'SwApCaSe'])
s.str.casefold()

0       lower
1    capitals
2         NaN
3    swapcase
dtype: object

Also see related GitHub issue GH25405.

casefold lends itself to more aggressive case-folding comparison. It also handles NaNs gracefully (just as str.lower does).

But why is this better?

The difference is seen with unicodes. Taking the example in the python str.casefold docs,

Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. For example, the German lowercase letter 'ß' is equivalent to "ss". Since it is already lowercase, lower() would do nothing to 'ß'; casefold() converts it to "ss".

Compare the output of lower for,

s = pd.Series(["der Fluß"])
s.str.lower()

0    der fluß
dtype: object

Versus casefold,

s.str.casefold()

0    der fluss
dtype: object

Also see Python: lower() vs. casefold() in string matching and converting to lowercase.

I don't hear about "apstring".If you want to use string with c++ ,you can do like this:

#include<string>
using namespace std;
int main()
{
   string str;
   cin>>str;
   cout<<str;
   ...
   return 0;
}

I hope this can avail

proposed solution edit works if you replace the row

Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

with

Set rDst = ThisWorkbook.Sheets("SomeSheet").Range("YourRange").Resize(rSrc.Rows.Count, rSrc.Columns.Count)

Presumably the method does something, and doesn't simply return?

Assuming this is the case, then:

1. If it modifies the state of it's owner object, then you should test that the state changed correctly.
2. If it takes in some object as a parameter and modifies that object, then your should test the object is correctly modified.
3. If it throws exceptions is certain cases, test that those exceptions are correctly thrown.
4. If its behaviour varies based on the state of its own object, or some other object, preset the state and test the method has the correct Ithrough one of the three test methods above).

If youy let us know what the method does, I could be more specific.

Here is a pretty simple stored procedure that does the trick as well...

    CREATE PROCEDURE GetBCPTable
    @table_name varchar(200)
AS
BEGIN
    DECLARE @raw_sql nvarchar(3000)

    DECLARE @columnHeader VARCHAR(8000)
    SELECT @columnHeader = COALESCE(@columnHeader+',' ,'')+ ''''+column_name +'''' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @table_name

    DECLARE @ColumnList VARCHAR(8000)
    SELECT @ColumnList = COALESCE(@ColumnList+',' ,'')+ 'CAST('+column_name +' AS VARCHAR)' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @table_name

    SELECT @raw_sql = 'SELECT '+ @columnHeader +' UNION ALL SELECT ' + @ColumnList + ' FROM ' + @table_name
    --PRINT @raw_SQL
    EXECUTE sp_executesql  @raw_sql
END
GO

Here is my re-thought solution for the problem. Still not perfect. The only true solution would be if the device manufacturers start to take seriously the "Mobile" and "Tablet" user-agent strings.

window.onload = userAgentDetect;
function userAgentDetect() {
  if(window.navigator.userAgent.match(/Mobile/i)
  || window.navigator.userAgent.match(/iPhone/i)
  || window.navigator.userAgent.match(/iPod/i)
  || window.navigator.userAgent.match(/IEMobile/i)
  || window.navigator.userAgent.match(/Windows Phone/i)
  || window.navigator.userAgent.match(/Android/i)
  || window.navigator.userAgent.match(/BlackBerry/i)
  || window.navigator.userAgent.match(/webOS/i)) {
    document.body.className += ' mobile';
    alert('True - Mobile - ' + navigator.userAgent);
  } else {
    alert('False - Mobile - ' + navigator.userAgent);
  }
  if(window.navigator.userAgent.match(/Tablet/i)
  || window.navigator.userAgent.match(/iPad/i)
  || window.navigator.userAgent.match(/Nexus 7/i)
  || window.navigator.userAgent.match(/Nexus 10/i)
  || window.navigator.userAgent.match(/KFAPWI/i)) {
    document.body.className -= ' mobile';
    document.body.className += ' tablet';
    alert('True - Tablet - ' + navigator.userAgent);
  } else {
    alert('False - Tablet - ' + navigator.userAgent);
  }
}

What happens when the Nexus 7 tablet only have the Android UA string? First, the Mobile become true, than later on the Tablet also become true, but Tablet will delete the Mobile UA string from the body tag.

CSS:

body.tablet { background-color: green; }
body.mobile { background-color: red; }

alert lines added for development. Chrome console can emulate many handheld devices. Test there.

EDIT:

Just don't use this, use feature detection instead. There are so many devices and brands out there that targeting a brand NEVER will be the right solution.

java.lang.VerifyError are the worst.

You would get this error if the bytecode size of your method exceeds the 64kb limit; but you would probably have noticed that.

Are you 100% sure this class isn't present in the classpath elsewhere in your application, maybe in another jar?

Also, from your stacktrace, is the character encoding of the source file (utf-8?) Is that correct?

Daniel Imms answer is excellent in regards to applying your CSS rotation to an inner element. However, it is possible to accomplish the end goal in a way that does not require JavaScript and works with longer strings of text.

Typically the whole reason to have vertical text in the first table column is to fit a long line of text in a short horizontal space and to go alongside tall rows of content (as in your example) or multiple rows of content (which I'll use in this example).

By using the ".rotate" class on the parent TD tag, we can not only rotate the inner DIV, but we can also set a few CSS properties on the parent TD tag that will force all of the text to stay on one line and keep the width to 1.5em. Then we can use some negative margins on the inner DIV to make sure that it centers nicely.

One thing to keep in mind with this solution is that it does not work well if the height of the row (or spanned rows) is shorter than the vertical text in the first column. It works best if you're spanning multiple rows or you have a lot of content creating tall rows.

Have fun playing around with this on jsFiddle.

Google's Android Documentation Says that :

An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called onPreExecute, doInBackground, onProgressUpdate and onPostExecute.

AsyncTask's generic types :

The three types used by an asynchronous task are the following:

Params, the type of the parameters sent to the task upon execution.
Progress, the type of the progress units published during the background computation.
Result, the type of the result of the background computation.

Not all types are always used by an asynchronous task. To mark a type as unused, simply use the type Void:

 private class MyTask extends AsyncTask<Void, Void, Void> { ... }

You Can further refer : http://developer.android.com/reference/android/os/AsyncTask.html

Or You Can clear whats the role of AsyncTask by refering Sankar-Ganesh's Blog

Well The structure of a typical AsyncTask class goes like :

private class MyTask extends AsyncTask<X, Y, Z>

    protected void onPreExecute(){

    }

This method is executed before starting the new Thread. There is no input/output values, so just initialize variables or whatever you think you need to do.

    protected Z doInBackground(X...x){

    }

The most important method in the AsyncTask class. You have to place here all the stuff you want to do in the background, in a different thread from the main one. Here we have as an input value an array of objects from the type “X” (Do you see in the header? We have “...extends AsyncTask” These are the TYPES of the input parameters) and returns an object from the type “Z”.

   protected void onProgressUpdate(Y y){

   }

This method is called using the method publishProgress(y) and it is usually used when you want to show any progress or information in the main screen, like a progress bar showing the progress of the operation you are doing in the background.

  protected void onPostExecute(Z z){

  }

This method is called after the operation in the background is done. As an input parameter you will receive the output parameter of the doInBackground method.

What about the X, Y and Z types?

As you can deduce from the above structure:

 X – The type of the input variables value you want to set to the background process. This can be an array of objects.

 Y – The type of the objects you are going to enter in the onProgressUpdate method.

 Z – The type of the result from the operations you have done in the background process.

How do we call this task from an outside class? Just with the following two lines:

MyTask myTask = new MyTask();

myTask.execute(x);

Where x is the input parameter of the type X.

Once we have our task running, we can find out its status from “outside”. Using the “getStatus()” method.

 myTask.getStatus();

and we can receive the following status:

RUNNING - Indicates that the task is running.

PENDING - Indicates that the task has not been executed yet.

FINISHED - Indicates that onPostExecute(Z) has finished.

Hints about using AsyncTask

1. Do not call the methods onPreExecute, doInBackground and onPostExecute manually. This is automatically done by the system.

2. You cannot call an AsyncTask inside another AsyncTask or Thread. The call of the method execute must be done in the UI Thread.

3. The method onPostExecute is executed in the UI Thread (here you can call another AsyncTask!).

4. The input parameters of the task can be an Object array, this way you can put whatever objects and types you want.

Use git log to obtain the hash key for specific version and then use git checkout <hashkey>

Note: Do not forget to type the hash before the last one. Last hash points your current position (HEAD) and changes nothing.

Here's the nicer (IMO) Swifty/Cocoa style syntax to achieve the same result as the other answers:

NSOperationQueue.mainQueue().addOperationWithBlock({
    // Your code here
})

Or you could grab the popular Async Swift library for even less code and more functionality:

Async.main {
    // Your code here
}

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

this.options[this.selectedIndex].innerHTML

should provide you with the "displayed" text of the selected item. this.value, like you said, merely provides the value of the value attribute.

Java 11 and newer

This solution is better than others and more portable:

Path cwd = Paths.get("").toAbsolutePath();

Or even

String cwd = Paths.get("").toAbsolutePath().toString();

Use the escape function of querystring. It generates a URL safe string.

var escaped_str = require('querystring').escape('Photo on 30-11-12 at 8.09 AM #2.jpg');
console.log(escaped_str);
// prints 'Photo%20on%2030-11-12%20at%208.09%20AM%20%232.jpg'

I had the same issue and I found that this happened after I installed an update for my SQL 2012. What fixed it for me was going into programs and features and running a repair on it.

I always use this link to see what type is the number I get with type():
LIST OF MAT TYPE IN OPENCV
I hope this can help you.

There are many ways to achieve this but the easiest way in Python 3.6+, in my opinion, is this:

print(f"{1:03}")

What you're looking for is setattr I believe. Use this to set an attribute on an object.

>>> def printme(s): print repr(s)
>>> class A: pass
>>> setattr(A,'printme',printme)
>>> a = A()
>>> a.printme() # s becomes the implicit 'self' variable
< __ main __ . A instance at 0xABCDEFG>

Snapshot Dependencies Snapshot dependencies are dependencies (JAR files) which are under development. Instead of constantly updating the version numbers to get the latest version, you can depend on a snapshot version of the project. Snapshot versions are always downloaded into your local repository for every build, even if a matching snapshot version is already located in your local repository. Always downloading the snapshot dependencies assures that you always have the latest version in your local repository, for every build.

your pom contains a lot of -SNAPSHOT dependencies and those -SNAPSHOT dependencies are a moving target

Adding the jquery*.js file reference twice can also cause the issue. It could be part of your bundle and you might have added to the page too. Hence you need to remove the additional reference like

I = imread('peppers.png');
H = fspecial('average', [5 5]);
I = imfilter(I, H);
imshow(I)

Note that filters can be applied to intensity images (2D matrices) using filter2, while on multi-dimensional images (RGB images or 3D matrices) imfilter is used.

Also on Intel processors, imfilter can use the Intel Integrated Performance Primitives (IPP) library to accelerate execution.

Please use this. You will get table names along with schema names:

SELECT SYSSCHEMA.NAME, SYSTABLE.NAME
FROM SYS.tables SYSTABLE
INNER JOIN SYS.SCHEMAS SYSSCHEMA
ON SYSTABLE.SCHEMA_ID = SYSSCHEMA.SCHEMA_ID

It would return NULL but if taken as BIGINT would show the number

Just for fun, this one also works.

a = num;
b = 0;
if (a % 10 == 0)
  return a == 0;
do {
  b = 10 * b + a % 10;
  if (a == b)
    return true;
  a = a / 10;
} while (a > b);
return a == b;

So, you essentially want to delete multiple elements in one pass? In that case, the position of the next element to delete will be offset by however many were deleted previously.

Our goal is to delete all the vowels, which are precomputed to be indices 1, 4, and 7. Note that its important the to_delete indices are in ascending order, otherwise it won't work.

to_delete = [1, 4, 7]
target = list("hello world")
for offset, index in enumerate(to_delete):
  index -= offset
  del target[index]

It'd be a more complicated if you wanted to delete the elements in any order. IMO, sorting to_delete might be easier than figuring out when you should or shouldn't subtract from index.

When you are not sure of the number of rows, then you can do it this way:

followers_df.index = range(len(followers_df))

You can't make the div a link itself, but you can make an <a> tag act as a block, the same behaviour a <div> has.

a {
    display: block;
}

You can then set the width and height on it.

Assuming code.cpp is the source code, the following will not throw errors:

make code
./code

Here the first command compiles the code and creates an executable with the same name, and the second command runs it. There is no need to specify g++ keyword in this case.

Sample Code:

ListView list = (ListView) findViewById(R.id.listview);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
      Object listItem = list.getItemAtPosition(position);
   } 
});

In the sample code above, the listItem should contain the selected data for the textView.

Try adding the RunAs option to your Start-Process

Start-Process powershell.exe -Credential $Credential -Verb RunAs -ArgumentList ("-file $args")

The default behaviour of divs is to take the full width available in their parent container.
This is the same as if you'd give the inner divs a width of 100%.

By floating the divs, they ignore their default and size their width to fit the content. Everything behind it (in the HTML), is placed under the div (on the rendered page).
This is the reason that they align theirselves next to each other.

The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it. A floating element is one where the computed value of float is not none.

Source: https://developer.mozilla.org/en-US/docs/Web/CSS/float

Get rid of the float, and the divs will be aligned under each other.
If this does not happen, you'll have some other css on divs or children of wrapper defining a floating behaviour or an inline display.

If you want to keep the float, for whatever reason, you can use clear on the 2nd div to reset the floating properties of elements before that element.
clear has 5 valid values: none | left | right | both | inherit. Clearing no floats (used to override inherited properties), left or right floats or both floats. Inherit means it'll inherit the behaviour of the parent element

Also, because of the default behaviour, you don't need to set the width and height on auto.
You only need this is you want to set a hardcoded height/width. E.g. 80% / 800px / 500em / ...

<div id="wrapper">
    <div id="inner1"></div>
    <div id="inner2"></div>
</div>

CSS is

#wrapper{
    margin-left:auto;
    margin-right:auto;
    height:auto; // this is not needed, as parent container, this div will size automaticly
    width:auto; // this is not needed, as parent container, this div will size automaticly
}

/*
You can get rid of the inner divs in the css, unless you want to style them.
If you want to style them identicly, you can use concatenation
*/
#inner1, #inner2 {
    border: 1px solid black;
}

A database contains one or more named schemas, which in turn contain tables. Schemas also contain other kinds of named objects, including data types, functions, and operators. The same object name can be used in different schemas without conflict; for example, both schema1 and myschema can contain tables named mytable. Unlike databases, schemas are not rigidly separated: a user can access objects in any of the schemas in the database he is connected to, if he has privileges to do so.

There are several reasons why one might want to use schemas:

To allow many users to use one database without interfering with each other.

To organize database objects into logical groups to make them more manageable.

Third-party applications can be put into separate schemas so they do not collide with the names of other objects.

Schemas are analogous to directories at the operating system level, except that schemas cannot be nested.

Official documentation can be referred https://www.postgresql.org/docs/9.1/ddl-schemas.html

Just to play with it, question is strong entity type and answer is weak. Question is always there, but an answer requires a question to exist.

Example: Don't ask 'Why?' if Your Dad's a Chemistry Professor

You might use ArrayList overloaded method toString()

String tmp=arr.toString();
PrintWriter pw=new PrintWriter(new FileOutputStream(file));
pw.println(tmp.substring(1,tmp.length()-1));

It's simple code to convert that to all lower case.

Not so simple to convert "true" back to "True", however.

true.ToString().ToLower() 

is what I use for xml output.

To make a translation in the controller you could use $translate service:

$translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
    vm.si = translations['COMMON.SI'];
    vm.no = translations['COMMON.NO'];
});

That statement only does the translation on controller activation but it doesn't detect the runtime change in language. In order to achieve that behavior, you could listen the $rootScope event: $translateChangeSuccess and do the same translation there:

    $rootScope.$on('$translateChangeSuccess', function () {
        $translate(['COMMON.SI', 'COMMON.NO']).then(function (translations) {
            vm.si = translations['COMMON.SI'];
            vm.no = translations['COMMON.NO'];
        });
    });

Of course, you could encapsulate the $translateservice in a method and call it in the controller and in the $translateChangeSucesslistener.

Just like leonbloy suggested, using two schemas in a database is the way to go. Suppose a source schema (old DB) and a target schema (new DB), you can try something like this (you should consider column names, types, etc.):

INSERT INTO target.Awards SELECT * FROM source.Nominations;

private void ClearFolder(string FolderName)
{
    DirectoryInfo dir = new DirectoryInfo(FolderName);

    foreach (FileInfo fi in dir.GetFiles())
    {
        fi.IsReadOnly = false;
        fi.Delete();
    }

    foreach (DirectoryInfo di in dir.GetDirectories())
    {
        ClearFolder(di.FullName);
        di.Delete();
    }
}

"This is my string with date in specified format $($theDate.ToString('u'))"

or

"This is my string with date in specified format $(Get-Date -format 'u')"

The sub-expression ($(...)) can include arbitrary expressions calls.

MSDN Documents both standard and custom DateTime format strings.

I've compared the different options for speed and found that – much to my surprise – all options (except diag) are equally fast. I personally use

A * b[:, None]

(or (A.T * b).T) because it's short.

Code to reproduce the plot:

def newaxis(data):
    A, b = data
    return A * b[:, numpy.newaxis]


def none(data):
    A, b = data
    return A * b[:, None]


def double_transpose(data):
    A, b = data
    return (A.T * b).T


def double_transpose_contiguous(data):
    A, b = data
    return numpy.ascontiguousarray((A.T * b).T)

I always use this:

function validEmail($email){
    // First, we check that there's one @ symbol, and that the lengths are right
    if (!preg_match("/^[^@]{1,64}@[^@]{1,255}$/", $email)) {
        // Email invalid because wrong number of characters in one section, or wrong number of @ symbols.
        return false;
    }
    // Split it into sections to make life easier
    $email_array = explode("@", $email);
    $local_array = explode(".", $email_array[0]);
    for ($i = 0; $i < sizeof($local_array); $i++) {
        if (!preg_match("/^(([A-Za-z0-9!#$%&'*+\/=?^_`{|}~-][A-Za-z0-9!#$%&'*+\/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$/", $local_array[$i])) {
            return false;
        }
    }
    if (!preg_match("/^\[?[0-9\.]+\]?$/", $email_array[1])) { // Check if domain is IP. If not, it should be valid domain name
        $domain_array = explode(".", $email_array[1]);
        if (sizeof($domain_array) < 2) {
            return false; // Not enough parts to domain
        }
        for ($i = 0; $i < sizeof($domain_array); $i++) {
            if (!preg_match("/^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$/", $domain_array[$i])) {
                return false;
            }
        }
    }

    return true;

pgpdump (https://www.lirnberger.com/tools/pgpdump/) is a tool that you can use to inspect pgp blocks.

It is not user friendly, and fairly technical, however,

• it parses public or private keys (without warning)
• it does not modify any keyring (sometimes it is not so clear what gpg does behind the hood, in my experience)
• it prints all packets, specifically userid's packets which shows the various text data about the keys.

unfortunately it does not read stdin : /

Try asmcrypto.js — it's really fast.

PS: I'm an author and I can answer your questions if any. Also I'd be glad to get some feedback :)

Just define your action method like this

public string ThemePath()

and simply return the string itself.

indexOf is case sensitive. This is because it uses the equals method to compare the elements in the list. The same thing goes for contains and remove.

Subclassing UITextField is the way to go. Open a playground and add the following code:

class MyTextField : UITextField {
    var leftTextMargin : CGFloat = 0.0

    override func textRectForBounds(bounds: CGRect) -> CGRect {
        var newBounds = bounds
        newBounds.origin.x += leftTextMargin
        return newBounds
    }

    override func editingRectForBounds(bounds: CGRect) -> CGRect {
        var newBounds = bounds
        newBounds.origin.x += leftTextMargin
        return newBounds
    }
}

let tf = MyTextField(frame: CGRect(x: 0, y: 0, width: 100, height: 44))
tf.text = "HELLO"
tf.leftTextMargin = 25
tf.setNeedsLayout()
tf.layoutIfNeeded()

Not my code, but I think it's pretty nicely written. It allows to check by the key as well as by the Object element itself and handles both the On Error method and iterating through all Collection elements.

I'll not copy the full explanation since it is available on the linked page. Solution itself copied in case the page eventually becomes unavailable in the future.

The doubt I have about the code is the overusage of GoTo in the first If block but that's easy to fix for anyone so I'm leaving the original code as it is.

'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'INPUT       : Kollection, the collection we would like to examine
'            : (Optional) Key, the Key we want to find in the collection
'            : (Optional) Item, the Item we want to find in the collection
'OUTPUT      : True if Key or Item is found, False if not
'SPECIAL CASE: If both Key and Item are missing, return False
Option Explicit
Public Function CollectionContains(Kollection As Collection, Optional Key As Variant, Optional Item As Variant) As Boolean
    Dim strKey As String
    Dim var As Variant

    'First, investigate assuming a Key was provided
    If Not IsMissing(Key) Then

        strKey = CStr(Key)

        'Handling errors is the strategy here
        On Error Resume Next
            CollectionContains = True
            var = Kollection(strKey) '<~ this is where our (potential) error will occur
            If Err.Number = 91 Then GoTo CheckForObject
            If Err.Number = 5 Then GoTo NotFound
        On Error GoTo 0
        Exit Function

CheckForObject:
        If IsObject(Kollection(strKey)) Then
            CollectionContains = True
            On Error GoTo 0
            Exit Function
        End If

NotFound:
        CollectionContains = False
        On Error GoTo 0
        Exit Function

    'If the Item was provided but the Key was not, then...
    ElseIf Not IsMissing(Item) Then

        CollectionContains = False '<~ assume that we will not find the item

        'We have to loop through the collection and check each item against the passed-in Item
        For Each var In Kollection
            If var = Item Then
                CollectionContains = True
                Exit Function
            End If
        Next var

    'Otherwise, no Key OR Item was provided, so we default to False
    Else
        CollectionContains = False
    End If

End Function

So ... you need to change some things in your code

<form method="POST" id="form-pass">
Password: <input type="text" name="pwd" id="input-pwd">
<input type="submit" value="Submit">
</form>

<script>
var form = document.querySelector('#form-pass');
var pwd = document.querySelector('#input-pwd');
pwd.focus();
form.onsubmit = checkForm;

function checkForm() {
  alert(pwd.value);
}
</script>

Try this way.

Compatibility with older browsers can be a drag, so be adviced.

If that is not a problem then go ahead. Run the snippet. Go to full page view and resize. Center will resize itself with no changes to the left or right divs.

Change left and right values to meet your requirement.

Thank you.

Hope this helps.

An additional solution with a different approach from the last mentioned solutions, is to check if your camera driver support the v4l2 camera controls (which is very common).
In the terminal just type:

v4l2-ctl -L

If your camera driver supports the v4l2 camera controls, you should get something like this (the list below depends on the controls that your camera driver supports):

               contrast (int)    : min=0 max=255 step=1 default=0 value=0 flags=slider
             saturation (int)    : min=0 max=255 step=1 default=64 value=64 flags=slider
                    hue (int)    : min=0 max=359 step=1 default=0 value=0 flags=slider
white_balance_automatic (bool)   : default=1 value=1 flags=update
            red_balance (int)    : min=0 max=4095 step=1 default=0 value=128 flags=inactive, slider
           blue_balance (int)    : min=0 max=4095 step=1 default=0 value=128 flags=inactive, slider
               exposure (int)    : min=0 max=65535 step=1 default=0 value=885 flags=inactive, volatile
         gain_automatic (bool)   : default=1 value=1 flags=update
                   gain (int)    : min=0 max=1023 step=1 default=0 value=32 flags=inactive, volatile
        horizontal_flip (bool)   : default=0 value=0
          vertical_flip (bool)   : default=0 value=0

And if you are lucky it supports horizontal_flip and vertical_flip.
Then all you need to do is to set the horizontal_flip by:

v4l2-ctl --set-ctrl horizontal_flip=1

or the vertical_flip by:

v4l2-ctl --set-ctrl vertical_flip=1

and then you can call your video device to capture a new video (see example below), and the video will be rotated/flipped.

ffmpeg -f v4l2 -video_size 640x480 -i /dev/video0 -vcodec libx264 -f mpegts input.mp4

Of-course that if you need to process an already existing video, than this method is not the solution you are looking for.

The advantage in this approach is that we flip the image in the sensor level, so the sensor of the driver already gives us the image flipped, and that's saves the application (like FFmpeg) any further and unnecessary processing.

I think you haven't messed up yet. Try:

git reset HEAD^

This will bring the dir to state before you've made the commit, HEAD^ means the parent of the current commit (the one you don't want anymore), while keeping changes from it (unstaged).

Use:

$intValue = 1;
$string = sprintf('%d', $intValue);

Or it could be:

$string = (string)$intValue;

Or:

settype(&$intValue, 'string');
