Good Solution is to get Nearest Round Number is

var=2.5
echo $var | awk '{print int($1+0.5)}'

Logic is simple if the var decimal value is less then .5 then closest value taken is integer value. Well if decimal value is more than .5 then next integer value gets added and since awk then takes only integer part. Issue solved

The files are using some sort of template engine in which curly braces indicate variables being generated by that templating engine, the files creating such variables must be present elsewhere with the more or less same name as the tpl file name. Here are some of templates engine mostly used.

Smarty

Savant

Tinybutstrong

etc

With smarty being widely used.

Aliases can be used only if they were introduced in the preceding step. So aliases in the SELECT clause can be used in the ORDER BY but not the GROUP BY clause.

WHERE
GROUP BY
WITH CUBE or WITH ROLLUP
HAVING
SELECT

Hope this helps.

Apart from the settings explained in the answer by @DarkNeuron:

"files.encoding": "any encoding"

you can also specify settings for a specific language like so:

"[language id]": {
  "files.encoding": "any encoding"
}

For example, I use this when I need to edit PowerShell files previously created with ISE (which are created in ANSI format):

"[powershell]": {
    "files.encoding": "windows1252"
}

You can get a list of identifiers of well-known languages here.

I experience problems on Eclipse Neon when editing a file which does not belong to the project directory. When I copy the same file to the project root directory, not even to the src directory, the completion starts working.

When the file is opened from a different directory, only completion for JRE works. That is for example: java. completes, but junit. does not.

You can use PdfBox from Apache which is simple to use and has good performance.

Here is an example of extracting text from a PDF file (you can read more here) :

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}

UPDATE:

You can get the text using PDFTextStripper:

PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created

There is a new open-source effort to develop a Java library for push notifications on Android, using the Meteor comet server as a backend. You can check it out at the Deacon Project Blog. We need developers, so please spread the word!

Instead of writing echo $cars.length write echo @($cars).length

You can only do so during a transaction.

BEGIN;
INSERT INTO xxx ...;
DELETE FROM ...;

Then you can either:

COMMIT; -- will confirm your changes

Or

ROLLBACK -- will undo your previous changes

You can find the answer here: Is there a minlength validation attribute in HTML5?

Therefore this should do the job:

<input pattern=".{6,6}">

It's simple with open source 7zip SFX-Packager - easy way to just "Drag & drop" folders onto it, and it creates a portable/self-extracting package.

I just want to add that you have to make sure your database is created with COLLATE utf8_general_ci or whichever collation you want to use, Else you might end up with another one than intended.

In phpmyadmin you can see the collation by clicking your database and choose operations. If you try create tables with another collation than your database, your tables will end up with the database collation anyways.

So make sure the collation for your database is right before creating tables. Hope this saves someone a few hours lol

Compare to null is undefined, unless you use IS NULL.

So, when comparing 3 to NULL (query A), it returns undefined.

I.e. SELECT 'true' where 3 in (1,2,null) and SELECT 'true' where 3 not in (1,2,null)

will produce the same result, as NOT (UNDEFINED) is still undefined, but not TRUE

As suat said, most of the time the connection refused is due to the fact that the port you set up is in use or there is a difference between the port number in your remote application debugging configuration in Eclipse and the port number used in the address attribute in

-Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=n.

Check those things. Thanks!

In HTML you can specify a mailto: address in the <form> element's [action] attribute.

<form action="mailto:[email protected]" method="GET">
    <input name="subject" type="text" />
    <textarea name="body"></textarea>
    <input type="submit" value="Send" />
</form>

What this will do is allow the user's email client to create an email prepopulated with the fields in the <form>.

What this will not do is send an email.

If you use the Eclipse "New Android Project" wizard in a recent ADT bundle, you'll automatically get tabs implemented as a Fragments. This makes the conversion of your application to the tablet format much easier in the future.

For simple single screen layouts you may still use Activity.

You should use Enum.TryParse to achive your goal

This is a example:

[Flags]
private enum TestEnum
{
    Value1 = 1,
    Value2 = 2
}

static void Main(string[] args)
{
    var enumName = "Value1";
    TestEnum enumValue;

    if (!TestEnum.TryParse(enumName, out enumValue))
    {
        throw new Exception("Wrong enum value");
    }

    // enumValue contains parsed value
}

sprintf: Writes formatted data to a character string in memory instead of stdout

Syntax of sprintf is:

#include <stdio.h>
int sprintf (char *string, const char *format
[,item [,item]…]);

Here,

String refers to the pointer to a buffer in memory where the data is to be written.

Format refers to pointer to a character string defining the format.

Each item is a variable or expression specifying the data to write.

The value returned by sprintf is greater than or equal to zero if the operation is successful or in other words the number of characters written, not counting the terminating null character is returned and returns a value less than zero if an error occurred.

printf: Prints to stdout

Syntax for printf is:

printf format [argument]…

The only difference between sprintf() and printf() is that sprintf() writes data into a character array, while printf() writes data to stdout, the standard output device.

You are use PHP isset

Example

if (isset($_GET["id"])) {
    echo $_GET["id"];
}

If you facing grant permission access denied problem, you can try mysql to fix the problem:

grant all privileges on . to root@'localhost' identified by 'Your password';

grant all privileges on . to root@'IP ADDRESS' identified by 'Your password?';

your can try this on any mysql user, its working.

Use below command to login mysql with iP address.

mysql -h 10.0.0.23 -u root -p

If you have robocopy,

robocopy C:\Folder1 D:\Folder2 /COPYALL /E

otherwise,

xcopy /e /v C:\Folder1 D:\Folder2

The first code line, Option Explicit means (in simple terms) that all of your variables have to be explicitly declared by Dim statements. They can be any type, including object, integer, string, or even a variant.

This line: Dim envFrmwrkPath As Range is declaring the variable envFrmwrkPath of type Range. This means that you can only set it to a range.

This line: Set envFrmwrkPath = ActiveSheet.Range("D6").Value is attempting to set the Range type variable to a specific Value that is in cell D6. This could be a integer or a string for example (depends on what you have in that cell) but it's not a range.

I'm assuming you want the value stored in a variable. Try something like this:

Dim MyVariableName As Integer
MyVariableName = ActiveSheet.Range("D6").Value

This assumes you have a number (like 5) in cell D6. Now your variable will have the value.

For simplicity sake of learning, you can remove or comment out the Option Explicit line and VBA will try to determine the type of variables at run time.

Try this to get through this part of your code

Dim envFrmwrkPath As String
Dim ApplicationName As String
Dim TestIterationName As String

It's impossible. document.cookie contains information in string like this:

key1=value1;key2=value2;...

So there isn't any information about dates.

You can store these dates in separate cookie variable:

auth_user=Riateche;auth_expire=01/01/2012

But user can change this variable.

If the list is of type system.collections.generic you can use the "CopyTo" method available to copy elements of your array to other sub arrays. You specify the start element and number of elements to copy.

You could also make 3 clones of your original list and use the "RemoveRange" on each list to shrink the list to the size you want.

Or just create a helper method to do it for you.

You can (but no longer should - see below!) use android.text.format.Time:

Time now = new Time();
now.setToNow();

From the reference linked above:

The Time class is a faster replacement for the java.util.Calendar and java.util.GregorianCalendar classes. An instance of the Time class represents a moment in time, specified with second precision.

NOTE 1: It's been several years since I wrote this answer, and it is about an old, Android-specific and now deprecated class. Google now says that "[t]his class has a number of issues and it is recommended that GregorianCalendar is used instead".

NOTE 2: Even though the Time class has a toMillis(ignoreDaylightSavings) method, this is merely a convenience to pass to methods that expect time in milliseconds. The time value is only precise to one second; the milliseconds portion is always 000. If in a loop you do

Time time = new Time();   time.setToNow();
Log.d("TIME TEST", Long.toString(time.toMillis(false)));
... do something that takes more than one millisecond, but less than one second ...

The resulting sequence will repeat the same value, such as 1410543204000, until the next second has started, at which time 1410543205000 will begin to repeat.

I'm not sure exactly what you mean by "full Git Bash environment", but I get the nice prompt if I do

"C:\Program Files\Git\bin\sh.exe" --login

In PowerShell

& 'C:\Program Files\Git\bin\sh.exe' --login

The --login switch makes the shell execute the login shell startup files.

You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.

var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type   = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);

<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>

I once solved this kind of problem by moving all inlines after the class definition and putting the #include for the other classes just before the inlines in the header file. This way one make sure all definitions+inlines are set prior the inlines are parsed.

Doing like this makes it possible to still have a bunch of inlines in both(or multiple) header files. But it's necessary to have include guards.

Like this

// File: A.h
#ifndef __A_H__
#define __A_H__
class B;
class A
{
    int _val;
    B *_b;
public:
    A(int val);
    void SetB(B *b);
    void Print();
};

// Including class B for inline usage here 
#include "B.h"

inline A::A(int val) : _val(val)
{
}

inline void A::SetB(B *b)
{
    _b = b;
    _b->Print();
}

inline void A::Print()
{
    cout<<"Type:A val="<<_val<<endl;
}

#endif /* __A_H__ */

...and doing the same in B.h

In Command line mode: I have planned on Linux OS.

1. download the latest jmeter version. Apache JMeter 3.2 (Requires Java 8 or later) as of now.

2. Extract in your desired directory. For example, extract to /tmp/

3. Now, default output file format will be csv. No need to change anything or specify in the CLI command. for example: ./jmeter -n -t examples/test.jmx -l examples/output.csv

For changing the default format, change the following parameter in jmeter.properties : jmeter.save.saveservice.output_format=xml

Now if you run the command : ./jmeter -n -t examples/test.jmx -l examples/output.jtl output get stored in xml format.

Now, make the request on multiple server(Additional info query): We can specify host and port as tags in

./jmeter -n -t examples/test.jmx -l examples/output.jtl -JHOST=<HOST> -JPORT=<PORT>

I know this is three years old, but thought it might be helpful to someone.

The concept is to use the :after (or :before) selector to position a border within the parent element.

    .container{
        position:relative; /*Position must be set to something*/
    }

    .container:after{
        position:relative;
        top: 0;
        content:"";
        left:0;
        height: 100%; /*Set pixel height and width if not defined in parent element*/
        width: 100%; 

        -webkit-box-sizing:border-box;
        -moz-box-sizing:border-box;
        -ms-box-sizing:border-box;
        box-sizing:border-box;

        border:1px solid #000; /*set your border style*/

    }

I first struggled to understand how the flush option was working. I wanted to do a 'loading display' and here is the solution I found:

for i in range(100000):
    print('{:s}\r'.format(''), end='', flush=True)
    print('Loading index: {:d}/100000'.format(i+1), end='')

The first line flushes the previous print and the second line prints a new updated message. I don't know if an one-line syntax exists here.

My 5 cents:

1. Use async/await if and only if you do an IO operation, like DB or external service webservice.
2. Always prefer async calls to DB.
3. Each time you query the DB.

P.S. There are exceptional cases for point 1, but you need to have a good understanding of async internals for this.

As an additional advantage, you can do few IO calls in parallel if needed:

Task task1 = FooAsync(); // launch it, but don't wait for result
Task task2 = BarAsync(); // launch bar; now both foo and bar are running
await Task.WhenAll(task1, task2); // this is better in regard to exception handling
// use task1.Result, task2.Result

To get a line-by-line memory and time analysis of your program, I suggest using memory_profiler and line_profiler.

Installation:

# Time profiler
$ pip install line_profiler
# Memory profiler
$ pip install memory_profiler
# Install the dependency for a faster analysis
$ pip install psutil

The common part is, you specify which function you want to analyse by using the respective decorators.

Example: I have several functions in my Python file main.py that I want to analyse. One of them is linearRegressionfit(). I need to use the decorator @profile that helps me profile the code with respect to both: Time & Memory.

Make the following changes to the function definition

@profile
def linearRegressionfit(Xt,Yt,Xts,Yts):
    lr=LinearRegression()
    model=lr.fit(Xt,Yt)
    predict=lr.predict(Xts)
    # More Code

For Time Profiling,

Run:

$ kernprof -l -v main.py

Output

Total time: 0.181071 s
File: main.py
Function: linearRegressionfit at line 35

    39         1       1347.0   1347.0      3.5      predict=lr.predict(Xts)
    40                                           
    41         1       4924.0   4924.0     12.8      print("train Accuracy",lr.score(Xt,Yt))

For Memory Profiling,

Run:

$ python -m memory_profiler main.py

Output

    42  130.547 MiB    0.000 MiB       print("test Accuracy",lr.score(Xts,Yts))

Also, the memory profiler results can also be plotted using matplotlib using

$ mprof run main.py
$ mprof plot

Note: Tested on

line_profiler version == 3.0.2

memory_profiler version == 0.57.0

psutil version == 5.7.0

EDIT: The results from the profilers can be parsed using the TAMPPA package. Using it, we can get line-by-line desired plots as

Excel Encodings

I found the WINDOWS-1252 encoding to be the least frustrating when dealing with Excel. Since its basically Microsofts own proprietary character set, one can assume it will work on both the Mac and the Windows version of MS-Excel. Both versions at least include a corresponding "File origin" or "File encoding" selector which correctly reads the data.

Depending on your system and the tools you use, this encoding could also be named CP1252, ANSI, Windows (ANSI), MS-ANSI or just Windows, among other variations.

This encoding is a superset of ISO-8859-1 (aka LATIN1 and others), so you can fallback to ISO-8859-1 if you cannot use WINDOWS-1252 for some reason. Be advised that ISO-8859-1 is missing some characters from WINDOWS-1252 as shown here:

Conversion

Conversion is done differently in every tool and language. However, suppose you have a file query_result.csv which you know is UTF-8 encoded. Convert it to WINDOWS-1252 using iconv:

iconv -f UTF-8 -t WINDOWS-1252 query_result.csv > query_result-win.csv

For me just ${workspace} worked without even initializing the variable 'workspace.'

Also, a good reason to use a controller vs. link function (since they both have access to the scope, element, and attrs) is because you can pass in any available service or dependency into a controller (and in any order), whereas you cannot do that with the link function. Notice the different signatures:

controller: function($scope, $exceptionHandler, $attr, $element, $parse, $myOtherService, someCrazyDependency) {...

vs.

link: function(scope, element, attrs) {... //no services allowed

XmlDocument d = new XmlDocument();
d.Load(@"D:\Work_Time_Calculator\10-07-2013.xml");
XmlNodeList n = d.GetElementsByTagName("Short_Fall");
if(n != null) {
    Console.WriteLine(n[0].InnerText); //Will output '08:29:57'
}

or you could wrap in foreach loop to print each value

XmlDocument d = new XmlDocument();
d.Load(@"D:\Work_Time_Calculator\10-07-2013.xml");
XmlNodeList n = d.GetElementsByTagName("Short_Fall");
if(n != null) {
    foreach(XmlNode curr in n) {
        Console.WriteLine(curr.InnerText);
    }
}

What do you get from running which port as your regular user account? Try it from a freshly opened terminal. Try again after renaming .bash_profile to .profile. Can you run port as a regular user, even with no arguments?

I used Barry example for my new development. It worked great! but i had to include a slightly change, required to dismiss the keyboard only for the textfield being edited.

So, I added to Barry example the following:

- (void) textFieldDidBeginEditing:(UITextField *)textField
{
    _textBeingEdited = textField;
}
-(void) textFieldDidEndEditing:(UITextField *)textField
{
    _textBeingEdited = nil;
}

Also, I changed hideKeyboard method as follows:

- (IBAction)hideKeyboard:(id)sender
{
    // Just call resignFirstResponder on all UITextFields and UITextViews in this VC
    // Why? Because it works and checking which one was last active gets messy.
    //UITextField * tf = (UITextField *) sender;
    [_textBeingEdited resignFirstResponder];
}

I'd rather trust JDK over System property. Following is a working snippet.

    private boolean checkIfStringContainsNewLineCharacters(String str){
        if(!StringUtils.isEmpty(str)){
            Scanner scanner = new Scanner(str);
            scanner.nextLine();
            boolean hasNextLine =  scanner.hasNextLine();
            scanner.close();
            return hasNextLine;
        }
        return false;
    }

Here's a simple query:

SELECT t1.ID
FROM Table1 t1
    LEFT JOIN Table2 t2 ON t1.ID = t2.ID
WHERE t2.ID IS NULL

The key points are:

1. LEFT JOIN is used; this will return ALL rows from Table1, regardless of whether or not there is a matching row in Table2.

2. The WHERE t2.ID IS NULL clause; this will restrict the results returned to only those rows where the ID returned from Table2 is null - in other words there is NO record in Table2 for that particular ID from Table1. Table2.ID will be returned as NULL for all records from Table1 where the ID is not matched in Table2.

With Tomcat 7, you can add the StuckThreadDetectionValve which will enable you to identify threads that are "stuck". You can set-up the valve in the Context element of the applications where you want to do detecting:

<Context ...>
  ...
  <Valve 
    className="org.apache.catalina.valves.StuckThreadDetectionValve"
    threshold="60" />
  ...
</Context>

This would write a WARN entry into the tomcat log for any thread that takes longer than 60 seconds, which would enable you to identify the applications and ban them because they are faulty.

Based on the source code you may be able to write your own valve that attempts to stop the thread, however this would have knock on effects on the thread pool and there is no reliable way of stopping a thread in Java without the cooperation of that thread...

SELECTs do not normally do any locking that you care about on InnoDB tables. The default transaction isolation level means that selects don't lock stuff.

Of course contention still happens.

Let's test 3 methods:
1)

public static double round1(double value, int scale) {
    return Math.round(value * Math.pow(10, scale)) / Math.pow(10, scale);
}

2)

public static float round2(float number, int scale) {
    int pow = 10;
    for (int i = 1; i < scale; i++)
        pow *= 10;
    float tmp = number * pow;
    return ( (float) ( (int) ((tmp - (int) tmp) >= 0.5f ? tmp + 1 : tmp) ) ) / pow;
}

3)

public static float round3(float d, int decimalPlace) {
    return BigDecimal.valueOf(d).setScale(decimalPlace, BigDecimal.ROUND_HALF_UP).floatValue();
}

Number is 0.23453f
We'll test 100,000 iterations each method.

Results:
Time 1 - 18 ms
Time 2 - 1 ms
Time 3 - 378 ms

Try to use text-align in style attribute to align center.

<th class="not_mapped_style" style="text-align:center">DisplayName</th>

You'd need to make the enum expose value somehow, e.g.

public enum Tax {
    NONE(0), SALES(10), IMPORT(5);

    private final int value;
    private Tax(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }
}

...

public int getTaxValue() {
    Tax tax = Tax.NONE; // Or whatever
    return tax.getValue();
}

(I've changed the names to be a bit more conventional and readable, btw.)

This is assuming you want the value assigned in the constructor. If that's not what you want, you'll need to give us more information.

I use a fake php array

<?php 
       // instead to create your array like this
       $php_array = ["The","quick","brown","fox","jumps","over","the","lazy","dog"];

       // do it like this (a simple variable but with separator)
       $php_fake_array = "The,quick,brown,fox,jumps,over,the,lazy,dog";
?>

<script type="text/javascript">

        // use the same separator for the JS split() function
        js_array = '<?php echo $php_fake_array; ?>'.split(',');

</script>

if ever your array is unknown (already made)

<?php 
        $php_array = file('my_file.txt');
        $php_fake_array = "";

        // transform your array with concatenate like this
        foreach ($php_array as $cell){

            // since this array is unknown, use clever separator
            $php_fake_array .= $cell.",,,,,"; 
        }
?>

<script type="text/javascript">

        // use the same separator for the JS split() function
        js_array = '<?php echo $php_fake_array; ?>'.split(',,,,,');

</script>

Modifying each element while iterating a list is fine, as long as you do not change add/remove elements to list.

You can use list comprehension:

l = ['a', ' list', 'of ', ' string ']
l = [item.strip() for item in l]

or just do the C-style for loop:

for index, item in enumerate(l):
    l[index] = item.strip()

PostgreSQL 12 supports generated columns:

PostgreSQL 12 Beta 1 Released!

Generated Columns

PostgreSQL 12 allows the creation of generated columns that compute their values with an expression using the contents of other columns. This feature provides stored generated columns, which are computed on inserts and updates and are saved on disk. Virtual generated columns, which are computed only when a column is read as part of a query, are not implemented yet.

Generated Columns

A generated column is a special column that is always computed from other columns. Thus, it is for columns what a view is for tables.

CREATE TABLE people (
    ...,
    height_cm numeric,
    height_in numeric GENERATED ALWAYS AS (height_cm * 2.54) STORED
);

As Maciej Jonczyk mentioned, you may also need to increase margins

par(las=2)
par(mar=c(8,8,1,1)) # adjust as needed
plot(...)

You could try hbase api methods!

org.apache.hadoop.hbase.client.coprocessor.AggregationClient

Does the column allow null?

Seems to work. Just tested with phpMyAdmin, the column is of type int that allows nulls:

INSERT INTO `database`.`table` (`column`) VALUES (NULL);

You can easily make lists of lists

list1 <- list(a = 2, b = 3)
list2 <- list(c = "a", d = "b")
mylist <- list(list1, list2)

mylist is now a list that contains two lists. To access list1 you can use mylist[[1]]. If you want to be able to something like mylist$list1 then you need to do somethingl like

mylist <- list(list1 = list1, list2 = list2)
# Now you can do the following
mylist$list1

Edit: To reply to your edit. Just use double bracket indexing

a <- list_all[[1]]
a[[1]]
#[1] 1
a[[2]]
#[1] 2

In addition to the answers above:

$ python3 -m timeit -s 'import os' 'os.environ.get("TERM_PROGRAM")'
200000 loops, best of 5: 1.65 usec per loop

$ python3 -m timeit -s 'import os' 'os.getenv("TERM_PROGRAM")'
200000 loops, best of 5: 1.83 usec per loop

As long as you are assigning a single variable, you can also use plain assignment in a plpgsql function:

name := (SELECT t.name from test_table t where t.id = x);

Or use SELECT INTO like @mu already provided.

This works, too:

name := t.name from test_table t where t.id = x;

But better use one of the first two, clearer methods, as @Pavel commented.

I shortened the syntax with a table alias additionally.
Update: I removed my code example and suggest to use IF EXISTS() instead like provided by @Pavel.

If you only need to execute only one command all by itself and no wait needed, you should try "cmd /c", this works for me!

cmd /c start iexplore "http://your/url.html"

cmd /c means executing a command and then exit.

You can learn the functions of your switches by typing in your command prompt

anycmd /?

This answer relates to modern setups (TypeScript 2.x, Webpack > 2.x)

You don't need to install @types/node (which is all of Node.js types and is irrelevant for front-end code, actually complicating things such as setTimout different return values, etc..

You do need to install @types/webpack-env

npm i -D @types/webpack-env

which gives the runtime signatures that Webpack has (including require, require.ensure, etc.)

Also make sure that your tsconfig.json file has no set 'types' array -> which will make it pickup all type definitions in your node_modules/@types folder.

If you want to restrict search of types you can set the typeRoot property to node_modules/@types.

Below code will only print files within directory and exclude directories within given directory while traversing.

#include <dirent.h>
#include <stdio.h>
#include <errno.h>
#include <sys/stat.h>
#include<string.h>
int main(void)
{
    DIR *d;
    struct dirent *dir;
    char path[1000]="/home/joy/Downloads";
    d = opendir(path);
    char full_path[1000];
    if (d)
    {
        while ((dir = readdir(d)) != NULL)
        {
            //Condition to check regular file.
            if(dir->d_type==DT_REG){
                full_path[0]='\0';
                strcat(full_path,path);
                strcat(full_path,"/");
                strcat(full_path,dir->d_name);
                printf("%s\n",full_path);
            }
        }
        closedir(d);
    }
    return(0);     
}

This looks like a CSV file, so you could use the python csv module to read it. For example:

import csv

crimefile = open(fileName, 'r')
reader = csv.reader(crimefile)
allRows = [row for row in reader]

Using the csv module allows you to specify how things like quotes and newlines are handled. See the documentation I linked to above.

You don't need to use the clipboard, you can export directly the whole resultset (not just what you see) to a file :

1. Execute your query
2. Right click any anywhere in the results
3. click "Export resultset..." to open the export wizard
4. Choose the format you want (CSV according to your question)
5. Review the settings in the next panes when clicking "Next".
6. Set the folder where the file will be created, and "Finish"

The export runs in the background, a popup will appear when it's done.

In newer versions of DBeaver you can just :

1. right click the SQL of the query you want to export
2. Execute > Export from query
3. Choose the format you want (CSV according to your question)
4. Review the settings in the next panes when clicking "Next".
5. Set the folder where the file will be created, and "Finish"

The export runs in the background, a popup will appear when it's done.

Compared to the previous way of doing exports, this saves you step 1 (executing the query) which can be handy with time/resource intensive queries.

This prints all elements that contain sub:

for s in filter (lambda x: sub in x, list): print (s)

// create table
var dt = new System.Data.DataTable("tableName");

// create fields
dt.Columns.Add("field1", typeof(int));
dt.Columns.Add("field2", typeof(string));
dt.Columns.Add("field3", typeof(DateTime));

// insert row values
dt.Rows.Add(new Object[]{
                123456,
                "test",
                DateTime.Now
           });

Since you are loading in the spans via ajax you will have to attach delegate handlers to the events to catch them as they bubble up.

$(document).on('click','span',function(e){
    console.log(e.target.id)
})

you will want to attach the event to the closest static member you can to increase efficiency.

$('#main_div').on('click','span',function(e){
    console.log(e.target.id)
})

is better than binding to the document for instance.

This question may help you understand

Direct vs. Delegated - jQuery .on()

skipUntil() with last()

skipUntil : ignore emitted items until another observable has emitted

last: emit last value from a sequence (i.e. wait until it completes then emit)

Note that anything emitted from the observable passed to skipUntil will cancel the skipping, which is why we need to add last() - to wait for the stream to complete.

main$.skipUntil(sequence2$.pipe(last()))

Official: https://rxjs-dev.firebaseapp.com/api/operators/skipUntil

Possible issue: Note that last() by itself will error if nothing is emitted. The last() operator does have a default parameter but only when used in conjunction with a predicate. I think if this situation is a problem for you (if sequence2$ may complete without emitting) then one of these should work (currently untested):

main$.skipUntil(sequence2$.pipe(defaultIfEmpty(undefined), last()))
main$.skipUntil(sequence2$.pipe(last(), catchError(() => of(undefined))

Note that undefined is a valid item to be emitted, but could actually be any value. Also note that this is the pipe attached to sequence2$ and not the main$ pipe.

pdfrw will let you read in pages from an existing PDF and draw them to a reportlab canvas (similar to drawing an image). There are examples for this in the pdfrw examples/rl1 subdirectory on github. Disclaimer: I am the pdfrw author.

From jQuery.ajax()

async Boolean
Default: true
By default, all requests are sent asynchronously (i.e. this is set to true by default). If you need synchronous requests, set this option to false.

So in your request, you must do async: false instead of async: "false".

Update:

The return value of ajaxSubmit is not the return value of the success: function(){...}. ajaxSubmit returns no value at all, which is equivalent to undefined, which in turn evaluates to true.

And that is the reason, why the form is always submitted and is independent of sending the request synchronous or not.

If you want to submit the form only, when the response is "Successful", you must return false from ajaxSubmit and then submit the form in the success function, as @halilb already suggested.

Something along these lines should work

function ajaxSubmit() {
    var password = $.trim($('#employee_password').val());
    $.ajax({
        type: "POST",
        url: "checkpass.php",
        data: "password="+password,
        success: function(response) {
            if(response == "Successful")
            {
                $('form').removeAttr('onsubmit'); // prevent endless loop
                $('form').submit();
            }
        }
    });

    return false;
}

Here is how you can read the entire file contents, and if done successfully, start a webserver which displays the JPG image in response to every request:

var http = require('http')
var fs = require('fs')

fs.readFile('image.jpg', function(err, data) {
  if (err) throw err // Fail if the file can't be read.
  http.createServer(function(req, res) {
    res.writeHead(200, {'Content-Type': 'image/jpeg'})
    res.end(data) // Send the file data to the browser.
  }).listen(8124)
  console.log('Server running at http://localhost:8124/')
})

Note that the server is launched by the "readFile" callback function and the response header has Content-Type: image/jpeg.

[Edit] You could even embed the image in an HTML page directly by using an <img> with a data URI source. For example:

  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body><img src="data:image/jpeg;base64,')
  res.write(Buffer.from(data).toString('base64'));
  res.end('"/></body></html>');

Use vertical-align:top; for the element you want at the top, as I have demonstrated on your jsfiddle.

http://www.brunildo.org/test/inline-block.html

The is no array.push(newValue) in C#. You don't push to an Array in C#. What we use for this is a List<T>. What you may want to consider (for teaching purpose only) is the ArrayList (no generic and it is a IList, so ...).

static void Main()
{
    // Create an ArrayList and add 3 elements.
    ArrayList list = new ArrayList();
    list.Add("One"); // Add is your push
    list.Add("Two");
    list.Add("Three");
}

After deserializing the JSON, you have a python object. Use the regular object methods.

In this case you have a list made of dictionaries:

json_object[0].items()

json_object[0]["title"]

etc.

I have almost exactly the same code as you and mine works.

Do you have jQueryUI.js included in the page?

There's a fiddle here

<input type="text" ng-model="date" jqdatepicker />
<br/>
{{ date }}


var datePicker = angular.module('app', []);

datePicker.directive('jqdatepicker', function () {
    return {
        restrict: 'A',
        require: 'ngModel',
         link: function (scope, element, attrs, ngModelCtrl) {
            element.datepicker({
                dateFormat: 'DD, d  MM, yy',
                onSelect: function (date) {
                    scope.date = date;
                    scope.$apply();
                }
            });
        }
    };
});

You'll also need the ng-app="app" somewhere in your HTML

It is possible for the TCP socket to be "closing" and your code to not have yet been notified.

Here is a animation for the life cycle. http://tcp.cs.st-andrews.ac.uk/index.shtml?page=connection_lifecycle

Basically, the connection was closed by the client. You already have throws IOException and SocketException extends IOException. This is working just fine. You just need to properly handle IOException because it is a normal part of the api.

EDIT: The RST packet occurs when a packet is received on a socket which does not exist or was closed. There is no difference to your application. Depending on the implementation the reset state may stick and closed will never officially occur.

    System.out.println("Enter testcase");
   int testcase=in.nextInt(); 
   while(testcase>0)
   {
     int a=in.nextInt();
     PlaindromeNumbers obj=new PlaindromeNumbers();
       System.out.println(obj.func(a));
       testcase--;
   }
}

}

the problem mainly is because the width have to be == to the height, and in the case of bs, the height is set to auto so here is a fix for that in js instead

function img_circle() {
    $('.img-circle').each(function() {
        $w = $(this).width();
        $(this).height($w);
    });
}

$(document).ready(function() {
    img_circle();
});

$(window).resize(function() {
    img_circle();
});

If nothing else works, which was the case for me, try making a new app id that is longer, more unique, and possibly add some numbers.

Worked for me.

Update Nov 2015:

Sometime in late 2015, the Google Developers Console interface was overhauled again. For the new interface:

1. Select your project from the toolbar.

2. Open the "Gallery" using hamburger menu icon on the left side of the toolbar and select 'API Manager'.

3. Click 'Credentials' in the left-hand navigation.

Alternatively, you can click 'Switch to old console' under the the three-dot menu (right side of the toolbar), then follow the instructions below.

For the NEW (edit: OLD) Google Developers Console:

You get your 'Developer key' (a.k.a. API key) on the same screen where you get your client ID/secret. (This is the 'Credentials' screen, which can be found under 'APIs & auth' in the left nav.)

Below your client ID keys, there is a section titled 'Public API access'. If there are no keys in this this section, click 'Create new Key'. Your developer key is the 'API key' specified here.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

If you have multiple versions and you want to run something by using a specific version, use this example:

/usr/libexec/java_home -v 1.7.0_75 --exec java -jar you-file.jar

I'm a bit late to the party, but here's a bit of jQuery I've been using:

$('.carousel').on('touchstart', function(event){
    const xClick = event.originalEvent.touches[0].pageX;
    $(this).one('touchmove', function(event){
        const xMove = event.originalEvent.touches[0].pageX;
        const sensitivityInPx = 5;

        if( Math.floor(xClick - xMove) > sensitivityInPx ){
            $(this).carousel('next');
        }
        else if( Math.floor(xClick - xMove) < -sensitivityInPx ){
            $(this).carousel('prev');
        }
    });
    $(this).on('touchend', function(){
        $(this).off('touchmove');
    });
});

No need for jQuery mobile or any other plugins. If you need to adjust the sensitivity of the swipe adjust the 5 and -5. Hope this helps someone.

Just setting Skip Install to YES did not work for me. Hopefully this will help somebody.

I went to dependence of my project targets: Coreplot-CocoaTouch. Then went to Coreplot-CocoaTouch Targets. In its Targets opened Build Phases. Then opened Copy Headers. There I had some of headers in Public, some in Private and some in Project. Moved ALL of them to Project.

Of course, in Build Settings of Coreplot-CocoaTouch Targets checked that Skip Install was set to YES in Deployment options.

And this time Archive made an archive that could be signed and .ipa produced.

I think you are using 'global' incorrectly. See Python reference. You should declare variable without global and then inside the function when you want to access global variable you declare it global yourvar.

#!/usr/bin/python

total

def checkTotal():
    global total
    total = 0

See this example:

#!/usr/bin/env python

total = 0

def doA():
    # not accessing global total
    total = 10

def doB():
    global total
    total = total + 1

def checkTotal():
    # global total - not required as global is required
    # only for assignment - thanks for comment Greg
    print total

def main():
    doA()
    doB()
    checkTotal()

if __name__ == '__main__':
    main()

Because doA() does not modify the global total the output is 1 not 11.

try this. Based on what type of output you want. sometime you may not need single quote around printed string.

test = "qweqwe\n1212as\t121\\2asas"
print(repr(test)) # output: 'qweqwe\n1212as\t121\\2asas'
print( repr(test).strip("'"))  # output: qweqwe\n1212as\t121\\2asas

for a big database you should either remove the database from the disk (after you stop the engine first I guess) or use in Cypher something like:

MATCH (n)
OPTIONAL MATCH (n)-[r]-()
WITH n,r LIMIT 50000
DELETE n,r
RETURN count(n) as deletedNodesCount

see https://zoomicon.wordpress.com/2015/04/18/howto-delete-all-nodes-and-relationships-from-neo4j-graph-database/ for some more info I've gathered on this from various answers

Yes, Python3.6 installs PIP but it is unreachable as it is installed. There is no code which will invoke it as it is! I have been at it for more than a week and I read every single advice given, without success!

Finally, I tested going to the pip directory and upgrading the installed version:

root@bx:/usr/local/lib/python3.6/site-packages # python -m pip install --upgrade pip

That command created a PIP which now works properly from any location on my FreeBSD server!

Clearly, the tools installed simply do not work, as installed with Python3.6. The only way to run them is to invoke Python and the desired python files as you can see in the command issued. Once the update is called, however, the new PIP works globally without having to invoke Python3.6...

Simply do this...hope it help

$fifteendaysago = date_create('15 days ago');
echo date_format($fifteendaysago, 'Y-m-d');

try this one - self.navigationController?.navigationItem.hidesBackButton = true

To make the change for one session, use this command:

:set tabstop=4

To make the change permanent, add it to ~/.vimrc or ~/.vim/vimrc:

set tabstop=4

This will affect all files, not just css. To only affect css files:

autocmd Filetype css setlocal tabstop=4

as stated in Michal's answer.

Make sure you have all the required software to run node-gyp:

• https://github.com/TooTallNate/node-gyp

You can configure version of Visual Studio used by node-gyp via an environment variable so you can avoid having to set the --msvs_version=2012 property every time you do an npm install.

Examples:

• set GYP_MSVS_VERSION=2012 for Visual Studio 2012
• set GYP_MSVS_VERSION=2013e (the 'e' stands for FREE 'express edition')

For the full list see - https://github.com/joyent/node/blob/v0.10.29/tools/gyp/pylib/gyp/MSVSVersion.py#L209-294

This is still painful for Windows users of NodeJS as it assumes you have a copy of Visual Studio installed and many end users will never have this. So I'm lobbying Joyent to the encourage them to include web sockets as part of CORE node and also to possible ship a GNU gcc compiler as part of NodeJS install so we can permanently fix this problem.

Feel free to add your vote at:

• https://github.com/joyent/node/issues/8005#issuecomment-50545326

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

In this simple example you can just put synchronized as a modifier after public in both method signatures.

More complex scenarios require other stuff.

The basic colours are RGB not RYB. Yes most of the softwares use the traditional RGB which can be used to mix together to form any other color i.e. RGB are the fundamental colours (as defined in Physics & Chemistry texts).

The printer user CMYK (cyan, magenta, yellow, and black) coloring as said by @jcomeau_ictx. You can view the following article to know about RGB vs CMYK: RGB Vs CMYK

A bit more information from the extract about them:

Red, Green, and Blue are "additive colors". If we combine red, green and blue light you will get white light. This is the principal behind the T.V. set in your living room and the monitor you are staring at now. Additive color, or RGB mode, is optimized for display on computer monitors and peripherals, most notably scanning devices.

Cyan, Magenta and Yellow are "subtractive colors". If we print cyan, magenta and yellow inks on white paper, they absorb the light shining on the page. Since our eyes receive no reflected light from the paper, we perceive black... in a perfect world! The printing world operates in subtractive color, or CMYK mode.

For anyone using Koa and koa-passport:

Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:

this.session.passport.user

When you set in done(null, user) in deserializeUser where 'user' is some user object from your database:

this.req.user OR this.passport.user

for some reason this.user Koa context never gets set when you call done(null, user) in your deserializeUser method.

So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:

app.use(function * setUserInContext (next) {
  this.user = this.req.user
  yield next
})

If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher

From Android O, you cant use the services for the long running background operations due to this, https://developer.android.com/about/versions/oreo/background . Jobservice will be the better option with Jobscheduler implementation.

I fixed the bug by changing the port which was

app.set('port', process.env.PORT || 3000);<br>

and changed to:

app.set('port', process.env.PORT || 8080);<br>

With ES6: This is now part of the language:

function myFunc(a, b = 0) {
   // function body
}

Please keep in mind that ES6 checks the values against undefined and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).

With ES5:

function myFunc(a,b) {
  b = b || 0;

  // b will be set either to b or to 0.
}

This works as long as all values you explicitly pass in are truthy. Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''

It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.

A more general approach would be to set the UIView's appearance's tintColor.

UIColor *myColor = [UIColor purpleColor];
[[UIView appearance] setTintColor:myColor];

Makes sense if you're using many default UI elements.

get-aduser -Server "servername" -Identity %username% -Properties *

get-aduser -Server "testdomain.test.net" -Identity testuser -Properties *

These work when you have the username. Also less to type than using the -filter property.

EDIT: Formatting.

PyCharm Community/Professional 2018.2.1

I was having this problem just now and I was able to solve it in sort of a similar way that @Beatriz Fonseca and @Julie pointed out.

If you go to File -> Settings -> Project: YourProjectName -> Project Structure, you'll have a directory layout of the project you're currently working in. You'll have to go through your directories and label them as being either the Source directory for all your Source files, or as a Resource folder for files that are strictly for importing.

You'll also want to make sure that you place __init__.py files within your resource directories, or really anywhere that you want to import from, and it'll work perfectly fine.

I hope this answer helps someone, and hopefully JetBrains will fix this annoying bug.

DateTime now = DateTime.Now;
int prevMonth = now.AddMonths(-1).Month;
int year = now.AddMonths(-1).Year;
int daysInPrevMonth = DateTime.DaysInMonth(year, prevMonth);
DateTime firstDayPrevMonth = new DateTime(year, prevMonth, 1);
DateTime lastDayPrevMonth = new DateTime(year, prevMonth, daysInPrevMonth);
Console.WriteLine("{0} {1}", firstDayPrevMonth.ToShortDateString(),
  lastDayPrevMonth.ToShortDateString());

If you are trying to call another exe file inside the bat-file. You must use SET Path inside the bat-file that you are calling. set Path should point into the directory there the exe-file is located:

set PATH=C:\;C:\DOS     {Sets C:\;C:\DOS as the current search path.} 

Null pointers and void pointers are completely different from each other. If we request the operating system(through malloc() in c langauge) to allocate memory for a particular data type then the operating system allocates memory in heap (if space is available in heap) and sends the address of the memory which was allocated.

When memory is allocated by os in heap then we can assign this address value in any pointer type variable of that data type. This pointer is then called a void pointer until it is not taken for any process.

When the space is not available in heap then the operating system certainly allocates memory and sends an address value of that location but this memory is not allocated in heap by the os because there is no space in heap,in this case this memory is allocated by the os in the system memory.. This memory can not be accessed by the user hence when we assign this address value in a pointer then this pointer is known as null pointer, and we cannot use this pointer. In the case of void pointer we can use it for any process in any programming language.

Similarly if you want link through s3Client you can use below.

System.out.println("filelink: " + s3Client.getUrl("your_bucket_name", "your_file_key"));

Doubles are just like floats, except for the fact that they are twice as large. This allows for a greater accuracy.

I think what you need might be simply:

\d( \w)?

Note that your regex would have worked too if it was written as \d \w|\d instead of \d|\d \w.

This is because in your case, once the regex matches the first option, \d, it ceases to search for a new match, so to speak.

If you need a transparent cut out edge, you can use a rotated pseudo element as a background for the div and position it to cut out the desired corner:

body {_x000D_
  background: url(http://i.imgur.com/k8BtMvj.jpg);_x000D_
  background-size: cover;_x000D_
}_x000D_
div {_x000D_
  position: relative;_x000D_
  width: 50%;_x000D_
  margin: 0 auto;_x000D_
  overflow: hidden;_x000D_
  padding: 20px;_x000D_
  text-align: center;_x000D_
}_x000D_
div:after {_x000D_
  content: '';_x000D_
  position: absolute;_x000D_
  width: 1100%; height: 1100%;_x000D_
  top: 20px; right: -500%;_x000D_
  background: rgba(255,255,255,.8);_x000D_
  transform-origin: 54% 0;_x000D_
  transform: rotate(45deg);_x000D_
  z-index: -1;_x000D_
}

<div>_x000D_
  ... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>_x000D_
</div>

Note that this solution uses transforms and you need to add the required vendor prefixes. For more info see canIuse.

To cut the bottom right edge, you can change the top, transform and transform-origin properties of the pseudo element to:

body {_x000D_
  background: url(http://i.imgur.com/k8BtMvj.jpg);_x000D_
  background-size: cover;_x000D_
}_x000D_
div {_x000D_
  position: relative;_x000D_
  width: 50%;_x000D_
  margin: 0 auto;_x000D_
  overflow: hidden;_x000D_
  padding: 20px;_x000D_
  text-align: center;_x000D_
}_x000D_
div:after {_x000D_
  content: '';_x000D_
  position: absolute;_x000D_
  width: 1100%; height: 1100%;_x000D_
  bottom: 20px; right: -500%;_x000D_
  background: rgba(255,255,255,.8);_x000D_
  transform-origin: 54% 100%;_x000D_
  transform: rotate(-45deg);_x000D_
  z-index: -1;_x000D_
}

<div>_x000D_
  ... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>... content ...<br/>_x000D_
</div>

Try this, it should work if you have configured your view resolver properly

 return "redirect:/index.html";

Go to the first line from which you would like to delete, and press the keys dG

In my programs, by convention, this is what the pre-existing $REPLY variable is for, which read uses for that exact purpose.

function getSomeString {
  REPLY="tadaa"
}

getSomeString
echo $REPLY

This echoes

tadaa

But to avoid conflicts, any other global variable will do.

declare result

function getSomeString {
  result="tadaa"
}

getSomeString
echo $result

If that isn’t enough, I recommend Markarian451’s solution.

You could use XDocument:

new XDocument(
    new XElement("root", 
        new XElement("someNode", "someValue")    
    )
)
.Save("foo.xml");

If the file you want to create is very big and cannot fit into memory you might use XmlWriter.

In v2.0 of the Graph API, calling /me/friends returns the person's friends who also use the app.

In addition, in v2.0, you must request the user_friends permission from each user. user_friends is no longer included by default in every login. Each user must grant the user_friends permission in order to appear in the response to /me/friends. See the Facebook upgrade guide for more detailed information, or review the summary below.

If you want to access a list of non-app-using friends, there are two options:

1. If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.

2. If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.

In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends permission). This has been confirmed by Facebook as 'by design'.

For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

UPDATE: Facebook have published an FAQ on these changes here: https://developers.facebook.com/docs/apps/faq which explain all the options available to developers in order to invite friends etc.

You can use plt.subplots_adjust to change the spacing between the subplots Link

subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)

left  = 0.125  # the left side of the subplots of the figure
right = 0.9    # the right side of the subplots of the figure
bottom = 0.1   # the bottom of the subplots of the figure
top = 0.9      # the top of the subplots of the figure
wspace = 0.2   # the amount of width reserved for blank space between subplots
hspace = 0.2   # the amount of height reserved for white space between subplots

Here is an even simplier way, by writing directly to php error output

curl_setopt($curl, CURLOPT_VERBOSE, true);
curl_setopt($curl, CURLOPT_STDERR, fopen('php://stderr', 'w'));

As of 2019 here is what I elaborated from the answers above and Guzzle docs to handle the exception, get the response body, status code, message and the other sometimes valuable response items.

try {
    /**
     * We use Guzzle to make an HTTP request somewhere in the
     * following theMethodMayThrowException().
     */
    $result = theMethodMayThrowException();
} catch (\GuzzleHttp\Exception\RequestException $e) {
    /**
     * Here we actually catch the instance of GuzzleHttp\Psr7\Response
     * (find it in ./vendor/guzzlehttp/psr7/src/Response.php) with all
     * its own and its 'Message' trait's methods. See more explanations below.
     *
     * So you can have: HTTP status code, message, headers and body.
     * Just check the exception object has the response before.
     */
    if ($e->hasResponse()) {
        $response = $e->getResponse();
        var_dump($response->getStatusCode()); // HTTP status code;
        var_dump($response->getReasonPhrase()); // Response message;
        var_dump((string) $response->getBody()); // Body, normally it is JSON;
        var_dump(json_decode((string) $response->getBody())); // Body as the decoded JSON;
        var_dump($response->getHeaders()); // Headers array;
        var_dump($response->hasHeader('Content-Type')); // Is the header presented?
        var_dump($response->getHeader('Content-Type')[0]); // Concrete header value;
    }
}
// process $result etc. ...

Voila. You get the response's information in conveniently separated items.

Side Notes:

With catch clause we catch the inheritance chain PHP root exception class \Exception as Guzzle custom exceptions extend it.

This approach may be useful for use cases where Guzzle is used under the hood like in Laravel or AWS API PHP SDK so you cannot catch the genuine Guzzle exception.

In this case, the exception class may not be the one mentioned in the Guzzle docs (e.g. GuzzleHttp\Exception\RequestException as the root exception for Guzzle).

So you have to catch \Exception instead but bear in mind it is still the Guzzle exception class instance.

Though use with care. Those wrappers may make Guzzle $e->getResponse() object's genuine methods not available. In this case, you will have to look at the wrapper's actual exception source code and find out how to get status, message, etc. instead of using Guzzle $response's methods.

If you call Guzzle directly yourself you can catch GuzzleHttp\Exception\RequestException or any other one mentioned in their exceptions docs with respect to your use case conditions.

hostname also works just fine in Powershell

Here's a simple wrapper for steven's answer. This function doesn't do repeated runs/averaging, just saves you from having to repeat the timing code everywhere :)

'''function which prints the wall time it takes to execute the given command'''
def time_func(func, *args): #*args can take 0 or more 
  import time
  start_time = time.time()
  func(*args)
  end_time = time.time()
  print("it took this long to run: {}".format(end_time-start_time))

There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.

If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.

Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.

Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.

Another good use for Dispatcher.Invoke is for immediately updating the UI in a function that performs other tasks:

// Force WPF to render UI changes immediately with this magic line of code...
Dispatcher.Invoke(new Action(() => { }), DispatcherPriority.ContextIdle);

I use this to update button text to "Processing..." and disable it while making WebClient requests.

You can also use the Pivot Keyword if you are using SQL 2005 or above

more info and from Technet

python -m pip uninstall pip setuptools

First a few words about apply() in JavaScript to help understand why we use it:

The apply() method calls a function with a given this value, and arguments provided as an array.

Push expects a list of items to add to the array. The apply() method, however, takes the expected arguments for the function call as an array. This allows us to easily push the elements of one array into another array with the builtin push() method.

Imagine you have these arrays:

var a = [1, 2, 3, 4];
var b = [5, 6, 7];

and simply do this:

Array.prototype.push.apply(a, b);

The result will be:

a = [1, 2, 3, 4, 5, 6, 7];

The same thing can be done in ES6 using the spread operator ("...") like this:

a.push(...b); //a = [1, 2, 3, 4, 5, 6, 7]; 

Shorter and better but not fully supported in all browsers at the moment.

Also if you want to move everything from array b to a, emptying b in the process, you can do this:

while(b.length) {
  a.push(b.shift());
} 

and the result will be as follows:

a = [1, 2, 3, 4, 5, 6, 7];
b = [];

A good information: you don't need to check whether the Bundle object is null into the onCreate() method. Use the onRestoreInstanceState() method, which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

If you hate recursion - using a Stack and javax.json to convert a Json String into a List of Maps:

import java.io.InputStream;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

        JsonParser parser = Json.createParser(is);

        String nextKey = "";
        Object nextval = "";
        Stack s = new Stack<>();
        while(parser.hasNext()) {
            JsonParser.Event event = parser.next();
            switch(event) {

                case VALUE_NUMBER : setValue(s,nextKey,parser.getLong());

                case VALUE_FALSE :  setValue(s,nextKey,false);
                                    break;
                case VALUE_NULL :   setValue(s,nextKey,"");
                                    break;
                case END_OBJECT :   
                case END_ARRAY  :   if(s.size() > 1) {
                                        // If this is not a root object, move up
                                        s.pop();

        return extracted;

    private static void setValue(Stack s, String nextKey, Object v) {
        if(Map.class.isAssignableFrom(s.peek().getClass()) ) ((Map)s.peek()).put(nextKey, v);
        else ((List)s.peek()).add(v);
    }
}

Since you can never depend on exact comparisons when dealing with floating point computations (such as these ways of calculating the square root), a less error-prone implementation would be

import math

def is_square(integer):
    root = math.sqrt(integer)
    return integer == int(root + 0.5) ** 2

Imagine integer is 9. math.sqrt(9) could be 3.0, but it could also be something like 2.99999 or 3.00001, so squaring the result right off isn't reliable. Knowing that int takes the floor value, increasing the float value by 0.5 first means we'll get the value we're looking for if we're in a range where float still has a fine enough resolution to represent numbers near the one for which we are looking.

Which version of C are you using?

In C90, the standard practice is to cast to signed or unsigned long, as appropriate, and print accordingly. I've seen %z for size_t, but Harbison and Steele don't mention it under printf(), and in any case that wouldn't help you with ptrdiff_t or whatever.

In C99, the various _t types come with their own printf macros, so something like "Size is " FOO " bytes." I don't know details, but that's part of a fairly large numeric format include file.

If the command that you are trying to execute fails, it would write the output onto the error stream and would then be printed out to the console.

To avoid it, you must redirect the error stream:

result=$(ls -l something_that_does_not_exist 2>&1)

My solution:

let isEmpty = (val) => {
    let typeOfVal = typeof val;
    switch(typeOfVal){
        case 'object':
            return (val.length == 0) || !Object.keys(val).length;
            break;
        case 'string':
            let str = val.trim();
            return str == '' || str == undefined;
            break;
        case 'number':
            return val == '';
            break;
        default:
            return val == '' || val == undefined;
    }
};
console.log(isEmpty([1,2,4,5])); // false
console.log(isEmpty({id: 1, name: "Trung",age: 29})); // false
console.log(isEmpty('TrunvNV')); // false
console.log(isEmpty(8)); // false
console.log(isEmpty('')); // true
console.log(isEmpty('   ')); // true
console.log(isEmpty([])); // true
console.log(isEmpty({})); // true

The above solutions didn't work for me because I needed to check out a specific tagged version of the tree. That's how cvs export is meant to be used, by the way. git checkout-index doesn't take the tag argument, as it checks out files from index. git checkout <tag> would change the index regardless of the work tree, so I would need to reset the original tree. The solution that worked for me was to clone the repository. Shared clone is quite fast and doesn't take much extra space. The .git directory can be removed if desired.

git clone --shared --no-checkout <repository> <destination>
cd <destination>
git checkout <tag>
rm -rf .git

Newer versions of git should support git clone --branch <tag> to check out the specified tag automatically:

git clone --shared --branch <tag> <repository> <destination>
rm -rf <destination>/.git

This will help you. DateFormat df = new SimpleDateFormat("dd/MM/yyyy"); print (df.format(new Date());

It is too late but helps someone, I'm using node version v7.9.0 and express version 4.15.0

if your directory structure is something like this:

your-project
   uploads
   package.json
   server.js

server.js code:

var express         = require('express');
var app             = express();
app.use(express.static(__dirname + '/uploads'));// you can access image 
 //using this url: http://localhost:7000/abc.jpg
//make sure `abc.jpg` is present in `uploads` dir.

//Or you can change the directory for hiding real directory name:

`app.use('/images', express.static(__dirname+'/uploads/'));// you can access image using this url: http://localhost:7000/images/abc.jpg


app.listen(7000);

I realize the following suggestion doesn't answer your question, but the simplest method I have found to capture a rapidly-changing DirectX view, is to plug a video camera into the S-video port of the video card, and record the images as a movie. Then transfer the video from the camera back to an MPG, WMV, AVI etc. file on the computer.

The answer by Nick Mitchinson is for Bootstrap version 2.

If you are using Bootstrap version 3, then forms have changed a bit. For bootstrap 3, use the following instead:

<div class="form-horizontal">
    <div class="form-group">
        <div class="col-md-6">
            <textarea class="form-control" rows="3" placeholder="What's up?" required></textarea>
        </div>
    </div>
</div>

Where, col-md-6 will target medium sized devices. You can add col-xs-6 etc to target smaller devices.

If your grid is bound to a DataTable, I believe you can just do:

// Should probably add a DBNull check for safety; but you get the idea.
long sum = (long)table.Compute("Sum(count)", "True");

If it isn't bound to a table, you could easily make it so:

var table = new DataTable();
table.Columns.Add("type", typeof(string));
table.Columns.Add("count", typeof(int));

// This will automatically create the DataGridView's columns.
dataGridView.DataSource = table;

What I have done in this situation is that I put in the option elements OnClick event like this:

<option onClick="something();">Option Name</option>

Then just create a script function like this:

function something(){
    alert("Hello"); 
    }

You may be able to approximate the size by pretending to serializing it with a binary serializer (but routing the output to oblivion) if you're working with serializable objects.

class Program
{
    static void Main(string[] args)
    {
        A parent;
        parent = new A(1, "Mike");
        parent.AddChild("Greg");
        parent.AddChild("Peter");
        parent.AddChild("Bobby");

        System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bf =
           new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
        SerializationSizer ss = new SerializationSizer();
        bf.Serialize(ss, parent);
        Console.WriteLine("Size of serialized object is {0}", ss.Length);
    }
}

[Serializable()]
class A
{
    int id;
    string name;
    List<B> children;
    public A(int id, string name)
    {
        this.id = id;
        this.name = name;
        children = new List<B>();
    }

    public B AddChild(string name)
    {
        B newItem = new B(this, name);
        children.Add(newItem);
        return newItem;
    }
}

[Serializable()]
class B
{
    A parent;
    string name;
    public B(A parent, string name)
    {
        this.parent = parent;
        this.name = name;
    }
}

class SerializationSizer : System.IO.Stream
{
    private int totalSize;
    public override void Write(byte[] buffer, int offset, int count)
    {
        this.totalSize += count;
    }

    public override bool CanRead
    {
        get { return false; }
    }

    public override bool CanSeek
    {
        get { return false; }
    }

    public override bool CanWrite
    {
        get { return true; }
    }

    public override void Flush()
    {
        // Nothing to do
    }

    public override long Length
    {
        get { return totalSize; }
    }

    public override long Position
    {
        get
        {
            throw new NotImplementedException();
        }
        set
        {
            throw new NotImplementedException();
        }
    }

    public override int Read(byte[] buffer, int offset, int count)
    {
        throw new NotImplementedException();
    }

    public override long Seek(long offset, System.IO.SeekOrigin origin)
    {
        throw new NotImplementedException();
    }

    public override void SetLength(long value)
    {
        throw new NotImplementedException();
    }
}

@FurkanO has provided the right approach. Though to go for a more cleaner approach (es6 way) you can do something like this

[{
    name: 'Sam',
    email: '[email protected]'
 },
 {
    name: 'Ash',
    email: '[email protected]'
 }
].map( ( {name, email} ) => {
    return <p key={email}>{name} - {email}</p>
})

Cheers!

Set the list style and left padding to nothing.

ul {
    list-style: none;
    padding-left: 0;
}?

ul {_x000D_
  list-style: none;_x000D_
  padding-left: 0;_x000D_
}

<ul>_x000D_
  <li>a</li>_x000D_
  <li>b</li>_x000D_
  <li>c</li>_x000D_
</ul>

To maintain the bullets you can replace the list-style: none with list-style-position: inside or the shorthand list-style: inside:

ul {
  list-style-position: inside;
  padding-left: 0;
}

ul {_x000D_
  list-style-position: inside;_x000D_
  padding-left: 0;_x000D_
}

<ul>_x000D_
  <li>a</li>_x000D_
  <li>b</li>_x000D_
  <li>c</li>_x000D_
</ul>

I did with

ssh-keygen -i -f $sshkeysfile >> authorized_keys

Credit goes here

it's probably better to override the backbutton so you can handle the event before the view is popped for things such as user confirmation.

in viewDidLoad create a UIBarButtonItem and set self.navigationItem.leftBarButtonItem to it passing in a sel

- (void) viewDidLoad
{
// change the back button to cancel and add an event handler
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@”back”
style:UIBarButtonItemStyleBordered
target:self
action:@selector(handleBack:)];

self.navigationItem.leftBarButtonItem = backButton;
[backButton release];

}
- (void) handleBack:(id)sender
{
// pop to root view controller
[self.navigationController popToRootViewControllerAnimated:YES];

}

Then you can do things like raise an UIAlertView to confirm the action, then pop the view controller, etc.

Or instead of creating a new backbutton, you can conform to the UINavigationController delegate methods to do actions when the back button is pressed.

Removing some unnecessary SQL and then COUNT(*) will be faster than SQL_CALC_FOUND_ROWS. Example:

SELECT Person.Id, Person.Name, Job.Description, Card.Number
FROM Person
JOIN Job ON Job.Id = Person.Job_Id
LEFT JOIN Card ON Card.Person_Id = Person.Id
WHERE Job.Name = 'WEB Developer'
ORDER BY Person.Name

Then count without unnecessary part:

SELECT COUNT(*)
FROM Person
JOIN Job ON Job.Id = Person.Job_Id
WHERE Job.Name = 'WEB Developer'

I did a quick performance check on these with perfplot (a project of mine) and found that it's hard to recommend anything else but numpy (note the log scale):

Code to reproduce the plot:

import perfplot
import numpy


def sorted_enumerate(seq):
    return [i for (v, i) in sorted((v, i) for (i, v) in enumerate(seq))]


def sorted_enumerate_key(seq):
    return [x for x, y in sorted(enumerate(seq), key=lambda x: x[1])]


def sorted_range(seq):
    return sorted(range(len(seq)), key=seq.__getitem__)


def numpy_argsort(x):
    return numpy.argsort(x)


perfplot.save(
    "argsort.png",
    setup=lambda n: numpy.random.rand(n),
    kernels=[sorted_enumerate, sorted_enumerate_key, sorted_range, numpy_argsort],
    n_range=[2 ** k for k in range(15)],
    xlabel="len(x)",
)

Java 8 and above

Using Java 8+ lambda expressions, if you have a class or interface with only a single abstract method (sometimes called a SAM type), for example:

public interface MyInterface {
    String doSomething(int param1, String param2);
}

then anywhere where MyInterface is used, you can substitute a lambda expression:

class MyClass {
    public MyInterface myInterface = (p1, p2) -> { return p2 + p1; };
}

For example, you can create a new thread very quickly:

new Thread(() -> someMethod()).start();

And use the method reference syntax to make it even cleaner:

new Thread(this::someMethod).start();

Without lambda expressions, these last two examples would look like:

new Thread(new Runnable() { someMethod(); }).start();

Before Java 8

A common pattern would be to 'wrap' it within an interface, like Callable, for example, then you pass in a Callable:

public T myMethod(Callable<T> func) {
    return func.call();
}

This pattern is known as the Command Pattern.

Keep in mind you would be best off creating an interface for your particular usage. If you chose to go with callable, then you'd replace T above with whatever type of return value you expect, such as String.

In response to your comment below you could say:

public int methodToPass() { 
        // do something
}

public void dansMethod(int i, Callable<Integer> myFunc) {
       // do something
}

then call it, perhaps using an anonymous inner class:

dansMethod(100, new Callable<Integer>() {
   public Integer call() {
        return methodToPass();
   }
});

Keep in mind this is not a 'trick'. It's just java's basic conceptual equivalent to function pointers.

This worked for me.

 1. git fetch --all
 2. git reset --hard origin/{branch_name}

You can bypass the security concerns, and create a much politer application by simply checking if the Word process is running, and asking the user to close it, then click a 'Continue' button in your app. This is the approach taken by many installers.

private bool isWordRunning() 
{
    return System.Diagnostics.Process.GetProcessesByName("winword").Length > 0;
}

Of course, you can only do this if your app has a GUI

The simplest I've been able to come up with is:

In [1]: import numpy as np

In [2]: arr = np.array([1, 3, 2, 4, 5])

In [3]: arr.argsort()[-3:][::-1]
Out[3]: array([4, 3, 1])

This involves a complete sort of the array. I wonder if numpy provides a built-in way to do a partial sort; so far I haven't been able to find one.

If this solution turns out to be too slow (especially for small n), it may be worth looking at coding something up in Cython.

Use a sub query similar to the below.

UPDATE P
SET extrasPrice = sub.TotalPrice from
BookingPitches p
inner join 
(Select PitchID, Sum(Price) TotalPrice
    from  dbo.BookingPitchExtras
    Where [Required] = 1
    Group by Pitchid
) as Sub
on p.Id = e.PitchId 
where p.BookingId = 1

Kill our own processes started from a common PPID is quite frequently, pkill associated to the –P flag is a winner for me. Using @ghostdog74 example :

# sleep 30 &                                                                                                      
[1] 68849
# sleep 30 &
[2] 68879
# sleep 30 &
[3] 68897
# sleep 30 &
[4] 68900
# pkill -P $$                                                                                                         
[1]   Terminated              sleep 30
[2]   Terminated              sleep 30
[3]-  Terminated              sleep 30
[4]+  Terminated              sleep 30

The appropriate way to read text files in Cocoa/Objective-C is documented in Apple's String programming guide. The section for reading and writing files should be just what you're after. PS: What's a "line"? Two sections of a string separated by "\n"? Or "\r"? Or "\r\n"? Or maybe you're actually after paragraphs? The previously mentioned guide also includes a section on splitting a string into lines or paragraphs. (This section is called "Paragraphs and Line Breaks", and is linked to in the left-hand-side menu of the page I pointed to above. Unfortunately this site doesn't allow me to post more than one URL as I'm not a trustworthy user yet.)

To paraphrase Knuth: premature optimisation is the root of all evil. Don't simply assume that "reading the whole file into memory" is slow. Have you benchmarked it? Do you know that it actually reads the whole file into memory? Maybe it simply returns a proxy object and keeps reading behind the scenes as you consume the string? (Disclaimer: I have no idea if NSString actually does this. It conceivably could.) The point is: first go with the documented way of doing things. Then, if benchmarks show that this doesn't have the performance you desire, optimise.

After digging a bit through the perlre docs a bit, I'll present my best suggestion so far that seems to work pretty good. Perl 5.10 added the \R character class as a generalized linebreak:

$line =~ s/\R//g;

It's the same as:

(?>\x0D\x0A?|[\x0A-\x0C\x85\x{2028}\x{2029}])

I'll keep this question open a while yet, just to see if there's more nifty ways waiting to be suggested.

The ab (apache bench) tool allows you to send many requests to a single page and you specify how many clients you want to be used and how many concurrent connection you want.

This may be the first step when developing a site. Just test some pages with a specific load. This way of benchmarking may have some problem, like caching being over used.

Later you may want a tool that simulate some concrete traffic and not for a single page. I don't have a refence handy on such tool yet.

Microsoft Azure offers a framework that makes it easy to perform this. http://azure.github.io/azure-mobile-services/iOS/v2/Classes/MSTable.html#//api/name/readWithQueryString:completion:

The google collections framework offers quote a good transform method,so you can transform your Objects into Strings. The only downside is that it has to be from Iterable to Iterable but this is the way I would do it:

Iterable<Object> objects = ....... //Your chosen iterable here
Iterable<String> strings = com.google.common.collect.Iterables.transform(objects, new Function<Object, String>(){
        String apply(Object from){
             return from.toString();
        }
 });

This take you away from using arrays,but I think this would be my prefered way.

This line calls the selector secondMethod after 3 seconds:

[self performSelector:@selector(secondMethod) withObject:nil afterDelay:3.0 ];

Use it on your second operation with your desired delay. If you have a lot of code, place it in its own method and call that method with performSelector:. It wont block the UI like sleep

Edit: If you do not want a second method you could add a category to be able to use blocks with performSelector:

@implementation NSObject (PerformBlockAfterDelay)

- (void)performBlock:(void (^)(void))block 
          afterDelay:(NSTimeInterval)delay
{
    block = [block copy];
    [self performSelector:@selector(fireBlockAfterDelay:) 
               withObject:block 
               afterDelay:delay];
}

- (void)fireBlockAfterDelay:(void (^)(void))block
{
    block();
}

@end

Or perhaps even cleaner:

void RunBlockAfterDelay(NSTimeInterval delay, void (^block)(void))
{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC*delay),
      dispatch_get_current_queue(), block);
}

Instructions

Things You'll Need

• Proficiency in C++
• C++ compiler
• Debugger and other investigative software tools

1

Understand the operator basics. The C++ operator new allocates heap memory. The delete operator frees heap memory. For every new, you should use a delete so that you free the same memory you allocated:

char* str = new char [30]; // Allocate 30 bytes to house a string.

delete [] str; // Clear those 30 bytes and make str point nowhere.

2

Reallocate memory only if you've deleted. In the code below, str acquires a new address with the second allocation. The first address is lost irretrievably, and so are the 30 bytes that it pointed to. Now they're impossible to free, and you have a memory leak:

char* str = new char [30]; // Give str a memory address.

// delete [] str; // Remove the first comment marking in this line to correct.

str = new char [60]; /* Give str another memory address with
                                                    the first one gone forever.*/

delete [] str; // This deletes the 60 bytes, not just the first 30.

3

Watch those pointer assignments. Every dynamic variable (allocated memory on the heap) needs to be associated with a pointer. When a dynamic variable becomes disassociated from its pointer(s), it becomes impossible to erase. Again, this results in a memory leak:

char* str1 = new char [30];

char* str2 = new char [40];

strcpy(str1, "Memory leak");

str2 = str1; // Bad! Now the 40 bytes are impossible to free.

delete [] str2; // This deletes the 30 bytes.

delete [] str1; // Possible access violation. What a disaster!

4

Be careful with local pointers. A pointer you declare in a function is allocated on the stack, but the dynamic variable it points to is allocated on the heap. If you don't delete it, it will persist after the program exits from the function:

void Leak(int x){

char* p = new char [x];

// delete [] p; // Remove the first comment marking to correct.

}

5

Pay attention to the square braces after "delete." Use delete by itself to free a single object. Use delete [] with square brackets to free a heap array. Don't do something like this:

char* one = new char;

delete [] one; // Wrong

char* many = new char [30];

delete many; // Wrong!

6

If the leak yet allowed - I'm usually seeking it with deleaker (check it here: http://deleaker.com).

Change the set of installed JREs in your eclipse. Window > Preferences > Java > Installed JREs, change the location of jre to %JAVA_HOME%/jre, but not something like C:\Program Files\Java\jre7

If you are able to wrap your XML in a root element - say then the following is your solution:

DECLARE @PersonsXml XML = '<persons><person><firstName>Jon</firstName><lastName>Johnson</lastName></person>
<person><firstName>Kathy</firstName><lastName>Carter</lastName></person>
<person><firstName>Bob</firstName><lastName>Burns</lastName></person></persons>'

SELECT  b.value('(./firstName/text())[1]','nvarchar(max)') as FirstName, b.value('(./lastName/text())[1]','nvarchar(max)') as LastName
FROM @PersonsXml.nodes('/persons/person') AS a(b)

In addition to the already excellent answers, also consider this function to retrieve both the number of dimensions and their bounds, which is similar to John's answer, but works and looks a little differently:

Function sizeOfArray(arr As Variant) As String
    Dim str As String
    Dim numDim As Integer

    numDim = NumberOfArrayDimensions(arr)
    str = "Array"

    For i = 1 To numDim
        str = str & "(" & LBound(arr, i) & " To " & UBound(arr, i)
        If Not i = numDim Then
            str = str & ", "
        Else
            str = str & ")"
        End If
    Next i

    sizeOfArray = str
End Function


Private Function NumberOfArrayDimensions(arr As Variant) As Integer
' By Chip Pearson
' http://www.cpearson.com/excel/vbaarrays.htm
Dim Ndx As Integer
Dim Res As Integer
On Error Resume Next
' Loop, increasing the dimension index Ndx, until an error occurs.
' An error will occur when Ndx exceeds the number of dimension
' in the array. Return Ndx - 1.
    Do
        Ndx = Ndx + 1
        Res = UBound(arr, Ndx)
    Loop Until Err.Number <> 0
NumberOfArrayDimensions = Ndx - 1
End Function

Example usage:

Sub arrSizeTester()
    Dim arr(1 To 2, 3 To 22, 2 To 9, 12 To 18) As Variant
    Debug.Print sizeOfArray(arr())
End Sub

And its output:

Array(1 To 2, 3 To 22, 2 To 9, 12 To 18)

In the latest R (3.2.3) there is a bug, preventing it some times from finding correct package. The workaround is to set repository manually:

install.packages("lubridate", dependencies=TRUE, repos='http://cran.rstudio.com/')

Found solution in other question

Try this:

CONCATENATE(""""; B2 ;"""")

@widor provided a nice solution alternative too - integrated with mine:

CONCATENATE(char(34); B2 ;char(34))

I am using node version manager. I was getting this error message because I had switched to a different version of node. When I switched back to the version of node where I installed bower, this error went away. In my case, the command was nvm use stable

This is old but as it is the first result in Google,

Please note that this also happens when your MySql service is down,

I fixed this by simply restarting MySQL Server using:

/etc/init.d/mysql restart

in SSH (Command is for a CentOS/CPanel server)

If you use C++11, you can use the specifier "override", and it will give you a compiler error if your aren't correctly overriding an abstract method. You probably have a method that doesn't match exactly with an abstract method in the base class, so your aren't actually overriding it.

http://en.cppreference.com/w/cpp/language/override

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

That's a problem with your version of jquery. Look here https://code.jquery.com/ and add this script

<script
  src="https://code.jquery.com/jquery-3.5.1.js"
  integrity="sha256-QWo7LDvxbWT2tbbQ97B53yJnYU3WhH/C8ycbRAkjPDc="
  crossorigin="anonymous">
</script>

I would think that now you have the range for each of the row, you can easily manipulate that range with the offset(row, column) action? What is the point of counting the records filtered (unless you need that count in a variable)? So instead of (or as well as in the same block) write your code action to move each row to an empty hidden sheet and once all done, you can do any work you like from the transferred range data?

Try this:

SELECT Count(*)
FROM <DATABASE_NAME>.INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

/**
 * @param filePath
 * @param fs
 * @return list of absolute file path present in given path
 * @throws FileNotFoundException
 * @throws IOException
 */
public static List<String> getAllFilePath(Path filePath, FileSystem fs) throws FileNotFoundException, IOException {
    List<String> fileList = new ArrayList<String>();
    FileStatus[] fileStatus = fs.listStatus(filePath);
    for (FileStatus fileStat : fileStatus) {
        if (fileStat.isDirectory()) {
            fileList.addAll(getAllFilePath(fileStat.getPath(), fs));
        } else {
            fileList.add(fileStat.getPath().toString());
        }
    }
    return fileList;
}

Quick Example : Suppose you have the following file structure:

a  ->  b
   ->  c  -> d
          -> e 
   ->  d  -> f

Using the code above, you get:

a/b
a/c/d
a/c/e
a/d/f

If you want only the leaf (i.e. fileNames), use the following code in else block :

 ...
    } else {
        String fileName = fileStat.getPath().toString(); 
        fileList.add(fileName.substring(fileName.lastIndexOf("/") + 1));
    }

This will give:

b
d
e
f

If you want to run a script to a database:

mysql -u user -p data_base_name_here < db.sql

The accepted answer is correct but needs to be wary that this way imposes a 255 character limit. Better to reference an actual worksheet range object.

For gitlab v10+ (as of Sept 2018), this has moved to settings-> repository -> default branch

As stated by @Luke this is still valid as on 4/1/2021

Lazy notes in comments.

#include <stdio.h>
// for malloc
#include <stdlib.h>

// you need the prototype
char *substring(int i,int j,char *ch);


int main(void /* std compliance */)
{
  int i=0,j=2;
  char s[]="String";
  char *test;
  // s points to the first char, S
  // *s "is" the first char, S
  test=substring(i,j,s); // so s only is ok
  // if test == NULL, failed, give up
  printf("%s",test);
  free(test); // you should free it
  return 0;
}


char *substring(int i,int j,char *ch)
{
  int k=0;
  // avoid calc same things several time
  int n = j-i+1; 
  char *ch1;
  // you can omit casting - and sizeof(char) := 1
  ch1=malloc(n*sizeof(char));
  // if (!ch1) error...; return NULL;

  // any kind of check missing:
  // are i, j ok? 
  // is n > 0... ch[i] is "inside" the string?...
  while(k<n)
    {   
      ch1[k]=ch[i];
      i++;k++;
    }   

  return ch1;
}

Here a bit easier:

@echo off
set /p var=Are You Sure?[Y/N]: 
if %var%== Y goto ...
if not %var%== Y exit

or

@echo off
echo Are You Sure?[Y/N]
choice /c YN
if %errorlevel%==1 goto yes
if %errorlevel%==2 goto no
:yes
echo yes
goto :EOF
:no
echo no

I would recommend node-cron. It allows to run tasks using Cron patterns e.g.

'* * * * * *' - runs every second
'*/5 * * * * *' - runs every 5 seconds
'10,20,30 * * * * *' - run at 10th, 20th and 30th second of every minute
'0 * * * * *' - runs every minute
'0 0 * * * *' - runs every hour (at 0 minutes and 0 seconds)

But also more complex schedules e.g.

'00 30 11 * * 1-5' - Runs every weekday (Monday through Friday) at 11:30:00 AM. It does not run on Saturday or Sunday.

Sample code: running job every 10 minutes:

var cron = require('cron');
var cronJob = cron.job("0 */10 * * * *", function(){
    // perform operation e.g. GET request http.get() etc.
    console.info('cron job completed');
}); 
cronJob.start();

You can find more examples in node-cron wiki

More on cron configuration can be found on cron wiki

I've been using that library in many projects and it does the job. I hope that will help.

I am using this to validate JSON Object

function isJsonObject(obj) {
    try {
        JSON.parse(JSON.stringify(obj));
    } catch (e) {
        return false;
    }
    return true;
}

I am using this to validate JSON String

function isJsonString(str) {
    try {
        JSON.parse(str);
    } catch (e) {
        return false;
    }
    return true;
}

If dealing with numbers that are either one or two digits:

'0'+str(number)[-2:] or '0{0}'.format(number)[-2:]

Its strange that such a simple setting would require this amount of 'hocus-pocus' to work.

To answer your question now, for me it seemed to work with the combination of the following:

:set wrap linebreak nolist

(this seems to prevent existing lines from breaking, just wrap.)

AND

set formatoptions=l

(this prevents new/edited lines from breaking, while += does not do it for me as other settings/plugins seem to find space and add their own options which override mine.)

I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:

@media all and (max-width: 600px) and (orientation:landscape) 
{
    /* styles here */
}

I had a similar problem.

Issue was there was a trigger on the table that would write changes to an audit log table. Columns were missing in audit log table.

dec = int(input("Enter a number below 256: "))
hex1 = dec // 16

if hex1 >= 10:
    hex1 = hex(dec)

hex2 = dec % 16
if hex2 >= 10:
    hex2 = hex(hex2)

print(hex1.strip("0x"))

Works well.

Seems to work fine.

If you have an empty BEGIN ... END block you might see

Msg 102, Level 15, State 1, Line 10 Incorrect syntax near 'END'.

I had the same issue. It was damaged the archive file...

in javascript, object properties can be accessed with . operator or with associative array indexing using []. ie. object.property is equivalent to object["property"]

this should do the trick

var smth = mydata.list[0]["points.bean.pointsBase"][0].time;

Try this:

Update TableB Set
  Code = Coalesce(
    (Select Max(Value)
    From TableA 
    Where Id = b.Id), 123)
From TableB b

If you're like me, when I first started using Java, I wanted to use the "==" operator to test whether two String instances were equal, but for better or worse, that's not the correct way to do it in Java.

In this tutorial I'll demonstrate several different ways to correctly compare Java strings, starting with the approach I use most of the time. At the end of this Java String comparison tutorial I'll also discuss why the "==" operator doesn't work when comparing Java strings.

Option 1: Java String comparison with the equals method Most of the time (maybe 95% of the time) I compare strings with the equals method of the Java String class, like this:

if (string1.equals(string2))

This String equals method looks at the two Java strings, and if they contain the exact same string of characters, they are considered equal.

Taking a look at a quick String comparison example with the equals method, if the following test were run, the two strings would not be considered equal because the characters are not the exactly the same (the case of the characters is different):

String string1 = "foo";
String string2 = "FOO";

if (string1.equals(string2))
{
    // this line will not print because the
    // java string equals method returns false:
    System.out.println("The two strings are the same.")
}

But, when the two strings contain the exact same string of characters, the equals method will return true, as in this example:

String string1 = "foo";
String string2 = "foo";

// test for equality with the java string equals method
if (string1.equals(string2))
{
    // this line WILL print
    System.out.println("The two strings are the same.")
}

Option 2: String comparison with the equalsIgnoreCase method

In some string comparison tests you'll want to ignore whether the strings are uppercase or lowercase. When you want to test your strings for equality in this case-insensitive manner, use the equalsIgnoreCase method of the String class, like this:

String string1 = "foo";
String string2 = "FOO";

 // java string compare while ignoring case
 if (string1.equalsIgnoreCase(string2))
 {
     // this line WILL print
     System.out.println("Ignoring case, the two strings are the same.")
 }

Option 3: Java String comparison with the compareTo method

There is also a third, less common way to compare Java strings, and that's with the String class compareTo method. If the two strings are exactly the same, the compareTo method will return a value of 0 (zero). Here's a quick example of what this String comparison approach looks like:

String string1 = "foo bar";
String string2 = "foo bar";

// java string compare example
if (string1.compareTo(string2) == 0)
{
    // this line WILL print
    System.out.println("The two strings are the same.")
}

While I'm writing about this concept of equality in Java, it's important to note that the Java language includes an equals method in the base Java Object class. Whenever you're creating your own objects and you want to provide a means to see if two instances of your object are "equal", you should override (and implement) this equals method in your class (in the same way the Java language provides this equality/comparison behavior in the String equals method).

You may want to have a look at this ==, .equals(), compareTo(), and compare()

You can also use PDCurses library. (http://pdcurses.sourceforge.net/)

For those trying to update config

If having trouble updating your npm config, try instead running using the -g flag. This solved the issue on Win 10 for me after trying everything else.

npm config edit -g

I am able to update the config and changes are reflected everywhere. This may be due to running npm in an organizational scope.

PDOStatement::getColumnMeta()

As Charle's mentioned, this is a statement method, meaning it fetches the column data from a prepared statement (query).

var x = document.cookie; 
window.alert(x);

This displays every cookie the current site has access to. If you for example have created two cookies "username=Frankenstein" and "username=Dracula", these two lines of code will display "username=Frankenstein; username=Dracula". However, information such as expiry date will not be shown.

AllDogs.First(d => d.Id == "2").Name = "some value";

However, a safer version of that might be this:

var dog = AllDogs.FirstOrDefault(d => d.Id == "2");
if (dog != null) { dog.Name = "some value"; }

Here is another way of doing it with a dictionary:

listA="The cat jumped over the house".split()
modify = {word:word for number,word in enumerate(listA)}
modify["cat"],modify["jumped"]="dog","walked"
print " ".join(modify[x] for x in listA)

ob_start();  // turns on output buffering
$foo->bar();  // all output goes only to buffer
ob_clean();  // delete the contents of the buffer, but remains buffering active
$foo->render(); // output goes to buffer
ob_flush(); // send buffer output
$none = ob_get_contents();  // buffer content is now an empty string
ob_end_clean();  // turn off output buffering

Buffers can be nested, so while one buffer is active, another ob_start() activates a new buffer. So ob_end_flush() and ob_flush() are not really sending the buffer to the output, but to the parent buffer. And only when there is no parent buffer, contents is sent to browser or terminal.

Nicely explained here: https://phpfashion.com/everything-about-output-buffering-in-php

Several consequences result from this difference between AWT and Swing.

AWT is a thin layer of code on top of the OS, whereas Swing is much larger. Swing also has very much richer functionality. Using AWT, you have to implement a lot of things yourself, while Swing has them built in. For GUI-intensive work, AWT feels very primitive to work with compared to Swing. Because Swing implements GUI functionality itself rather than relying on the host OS, it can offer a richer environment on all platforms Java runs on. AWT is more limited in supplying the same functionality on all platforms because not all platforms implement the same-looking controls in the same ways.

Swing components are called "lightweight" because they do not require a native OS object to implement their functionality. JDialog and JFrame are heavyweight, because they do have a peer. So components like JButton, JTextArea, etc., are lightweight because they do not have an OS peer.

A peer is a widget provided by the operating system, such as a button object or an entry field object.
