in case some extra manipulation of the data is desired, for which the user wants a function, this approach is not perfect (as it requires passing the class of the element as second parameter), but works:

import java.util.ArrayList; import java.lang.reflect.Array;

public class Test {
  public static void main(String[] args) {
    ArrayList<Integer> al = new ArrayList<>();
    al.add(1);
    al.add(2);
    Integer[] arr = convert(al, Integer.class);
    for (int i=0; i<arr.length; i++)
      System.out.println(arr[i]);
  }

  public static <T> T[] convert(ArrayList<T> al, Class clazz) {
    return (T[]) al.toArray((T[])Array.newInstance(clazz, al.size()));
  }
}

Use the LLVM/Clang Static Analyzer

NOTE: Under Xcode 4 this is now built into the IDE.

You use the Clang Static Analyzer to -- unsurprisingly -- analyse your C and Objective-C code (no C++ yet) on Mac OS X 10.5. It's trivial to install and use:

1. Download the latest version from this page.
2. From the command-line, cd to your project directory.
3. Execute scan-build -k -V xcodebuild.

(There are some additional constraints etc., in particular you should analyze a project in its "Debug" configuration -- see http://clang.llvm.org/StaticAnalysisUsage.html for details -- the but that's more-or-less what it boils down to.)

The analyser then produces a set of web pages for you that shows likely memory management and other basic problems that the compiler is unable to detect.

In Oracle you can do this:

SELECT * FROM table1 WHERE (col_a,col_b) IN (SELECT col_x,col_y FROM table2)

You can't convert an integer value straight to a date but you can first it to a datetime then to a date type

select cast(40835 as datetime)

and then convert to a date (SQL 2008)

select cast(cast(40835 as datetime) as date)

For me, it had something to do with file permissions. Someone with Mac/Linux on my project seems to commit some files with non-default permissions which my Windows git client failed to reproduce. Solution for me was to tell git to ignore file permissions:

git config core.fileMode false

Other insight: How do I make Git ignore file mode (chmod) changes?

I've developed an almost flawless try & catch implementation in bash, that allows you to write code like:

try 
    echo 'Hello'
    false
    echo 'This will not be displayed'

catch 
    echo "Error in $__EXCEPTION_SOURCE__ at line: $__EXCEPTION_LINE__!"

You can even nest the try-catch blocks inside themselves!

try {
    echo 'Hello'

    try {
        echo 'Nested Hello'
        false
        echo 'This will not execute'
    } catch {
        echo "Nested Caught (@ $__EXCEPTION_LINE__)"
    }

    false
    echo 'This will not execute too'

} catch {
    echo "Error in $__EXCEPTION_SOURCE__ at line: $__EXCEPTION_LINE__!"
}

The code is a part of my bash boilerplate/framework. It further extends the idea of try & catch with things like error handling with backtrace and exceptions (plus some other nice features).

Here's the code that's responsible just for try & catch:

set -o pipefail
shopt -s expand_aliases
declare -ig __oo__insideTryCatch=0

# if try-catch is nested, then set +e before so the parent handler doesn't catch us
alias try="[[ \$__oo__insideTryCatch -gt 0 ]] && set +e;
           __oo__insideTryCatch+=1; ( set -e;
           trap \"Exception.Capture \${LINENO}; \" ERR;"
alias catch=" ); Exception.Extract \$? || "

Exception.Capture() {
    local script="${BASH_SOURCE[1]#./}"

    if [[ ! -f /tmp/stored_exception_source ]]; then
        echo "$script" > /tmp/stored_exception_source
    fi
    if [[ ! -f /tmp/stored_exception_line ]]; then
        echo "$1" > /tmp/stored_exception_line
    fi
    return 0
}

Exception.Extract() {
    if [[ $__oo__insideTryCatch -gt 1 ]]
    then
        set -e
    fi

    __oo__insideTryCatch+=-1

    __EXCEPTION_CATCH__=( $(Exception.GetLastException) )

    local retVal=$1
    if [[ $retVal -gt 0 ]]
    then
        # BACKWARDS COMPATIBILE WAY:
        # export __EXCEPTION_SOURCE__="${__EXCEPTION_CATCH__[(${#__EXCEPTION_CATCH__[@]}-1)]}"
        # export __EXCEPTION_LINE__="${__EXCEPTION_CATCH__[(${#__EXCEPTION_CATCH__[@]}-2)]}"
        export __EXCEPTION_SOURCE__="${__EXCEPTION_CATCH__[-1]}"
        export __EXCEPTION_LINE__="${__EXCEPTION_CATCH__[-2]}"
        export __EXCEPTION__="${__EXCEPTION_CATCH__[@]:0:(${#__EXCEPTION_CATCH__[@]} - 2)}"
        return 1 # so that we may continue with a "catch"
    fi
}

Exception.GetLastException() {
    if [[ -f /tmp/stored_exception ]] && [[ -f /tmp/stored_exception_line ]] && [[ -f /tmp/stored_exception_source ]]
    then
        cat /tmp/stored_exception
        cat /tmp/stored_exception_line
        cat /tmp/stored_exception_source
    else
        echo -e " \n${BASH_LINENO[1]}\n${BASH_SOURCE[2]#./}"
    fi

    rm -f /tmp/stored_exception /tmp/stored_exception_line /tmp/stored_exception_source
    return 0
}

Another way (although essentially equivalent to the new ArrayList(Arrays.asList(array)) solution performance-wise:

Collections.addAll(arraylist, array);

It's the "frame" or "range" clause of window functions, which are part of the SQL standard and implemented in many databases, including Teradata.

A simple example would be to calculate the average amount in a frame of three days. I'm using PostgreSQL syntax for the example, but it will be the same for Teradata:

WITH data (t, a) AS (
  VALUES(1, 1),
        (2, 5),
        (3, 3),
        (4, 5),
        (5, 4),
        (6, 11)
)
SELECT t, a, avg(a) OVER (ORDER BY t ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING)
FROM data
ORDER BY t

... which yields:

t  a  avg
----------
1  1  3.00
2  5  3.00
3  3  4.33
4  5  4.00
5  4  6.67
6 11  7.50

As you can see, each average is calculated "over" an ordered frame consisting of the range between the previous row (1 preceding) and the subsequent row (1 following).

When you write ROWS UNBOUNDED PRECEDING, then the frame's lower bound is simply infinite. This is useful when calculating sums (i.e. "running totals"), for instance:

WITH data (t, a) AS (
  VALUES(1, 1),
        (2, 5),
        (3, 3),
        (4, 5),
        (5, 4),
        (6, 11)
)
SELECT t, a, sum(a) OVER (ORDER BY t ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW)
FROM data
ORDER BY t

yielding...

t  a  sum
---------
1  1    1
2  5    6
3  3    9
4  5   14
5  4   18
6 11   29

Here's another very good explanations of SQL window functions.

Try this one in model class

    [Required(ErrorMessage = "Enter full name.")]
    [RegularExpression("([A-Za-z])+( [A-Za-z]+)", ErrorMessage = "Enter valid full name.")]

    public string FullName { get; set; }

For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.

The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)

Using this regex:

^(?!.*function).*(\&\$)

it is possible to search project-wide for the occurrence of &$ only in lines that are not a function definition.

This still turns up a lot of false positives, but it does make the job easier.

VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.

DecimalFormat decimalFormat = new DecimalFormat(".#");
String result = decimalFormat.format(12.763);                // -->  12.7

To check if a directory named "Folder" exists use:

QDir("Folder").exists();

To create a new folder named "MyFolder" use:

QDir().mkdir("MyFolder");

Thanks for the Answer I have modified the statements to look like below

SELECT
     AlarmEventTransactionTable.TxnID,
     CASE 
    WHEN DeviceID IN('7', '10', '62', '58', '60',
            '46', '48', '50', '137', '139',
             '141', '145', '164') THEN '01'
    WHEN DeviceID IN('8', '9', '63', '59', '61',
            '47', '49', '51', '138', '140',
            '142', '146', '165') THEN '02'
             ELSE 'NA' END AS clocking,
     AlarmEventTransactionTable.DateTimeOfTxn
FROM
     multiMAXTxn.dbo.AlarmEventTransactionTable

I had the same problem.

My project directory was like this:

    --project
    ---Classes
    ----Application
    -----.h and .c files
    ----OtherFolders
    --main.cpp

And what I used to include the files in all those folders:

    file(GLOB source_files
            "*.h"
            "*.cpp"
            "Classes/*/*.cpp"
            "Classes/*/*.h"
    )

    add_executable(Server ${source_files})

And it totally worked.

A transaction isn't needed here, this should suffice:

function add_post($post_data) {
    $this->db->insert('posts',$post_data);
    return $this->db->insert_id();
}

I wanted to show how powerful it can be aside from just checking "-lt".

Example: I used it to calculate time differences take from Windows event view Application log:

Get the difference between the two date times:

PS> $Obj = ((get-date "10/22/2020 12:51:1") - (get-date "10/22/2020 12:20:1 "))

Object created:

PS> $Obj


Days              : 0
Hours             : 0
Minutes           : 31
Seconds           : 0
Milliseconds      : 0
Ticks             : 18600000000
TotalDays         : 0.0215277777777778
TotalHours        : 0.516666666666667
TotalMinutes      : 31
TotalSeconds      : 1860
TotalMilliseconds : 1860000

Access an item directly:

PS> $Obj.Minutes
31

You can use the charCodeAt() method to check if the specified character has a value higher than 127 and convert it to a numeric character reference using toString(16).

I got a better method from here: WCF: Creating Custom Headers, How To Add and Consume Those Headers

Client Identifies Itself
The goal here is to have the client provide some sort of information which the server can use to determine who is sending the message. The following C# code will add a header named ClientId:

var cl = new ActiveDirectoryClient();

var eab = new EndpointAddressBuilder(cl.Endpoint.Address);

eab.Headers.Add( AddressHeader.CreateAddressHeader("ClientId",       // Header Name
                                                   string.Empty,     // Namespace
                                                    "OmegaClient")); // Header Value
cl.Endpoint.Address = eab.ToEndpointAddress();

// Now do an operation provided by the service.
cl.ProcessInfo("ABC");

What that code is doing is adding an endpoint header named ClientId with a value of OmegaClient to be inserted into the soap header without a namespace.

Custom Header in Client’s Config File
There is an alternate way of doing a custom header. That can be achieved in the Xml config file of the client where all messages sent by specifying the custom header as part of the endpoint as so:

<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IActiveDirectory" />
            </basicHttpBinding>
        </bindings>
        <client>
          <endpoint address="http://localhost:41863/ActiveDirectoryService.svc"
              binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IActiveDirectory"
              contract="ADService.IActiveDirectory" name="BasicHttpBinding_IActiveDirectory">
            <headers>
              <ClientId>Console_Client</ClientId>
            </headers>
          </endpoint>
        </client>
    </system.serviceModel>
</configuration>

It seems your solution is not much ugly. You can use functions and make it proffesional like these ways

• first way

new.function <- function(filename){
  readChar(filename, file.info(filename)$size)
}

new.function('foo.txt')

• second way

new.function <- function(){
  filename <- 'foo.txt'
  return (readChar(filename, file.info(filename)$size))
}

new.function()

You can use the .Clear method:

Sheets("Zeros").UsedRange.Clear

Using this you can remove the contents and the formatting of a cell or range without affecting the rest of the worksheet.

The built in FTP command doesn't have a facility for security. Use cUrl instead. It's scriptable, far more robust and has FTP security.

You can't change the height of the br tag itself, as it's not an element that takes up space in the page. It's just an instruction to create a new line.

You can change the line height using the line-height style. That will change the distance between the text blocks that you have separated by empty lines, but natually also the distance between lines in a text block.

For completeness: Text blocks in HTML is usually done using the p tag around text blocks. That way you can control the line height inside the p tag, and also the spacing between the p tags.

If you can't access https://dl-ssl.google.com/android/eclipse/ simply try to use http:// instead of https://

There is one way to do this, as long as you have regular time intervals between all your date-time values - make the x-axis consider the values as text.

You should use the csv module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows([row[2:4] for _ in range(count)])

or, using the itertools module to do the repeating with itertools.repeat():

from itertools import repeat
import csv

with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
    tsvin = csv.reader(tsvin, delimiter='\t')
    csvout = csv.writer(csvout)

    for row in tsvin:
        count = int(row[4])
        if count > 0:
            csvout.writerows(repeat(row[2:4], count))

Even array2.extend(array1) will work.

    // acos(0.0) will return value of pi/2, inverse of cos(0) is pi/2 
    double pi = 2 * acos(0.0);
    int n; // upto 6 digit
    scanf("%d",&n); //precision with which you want the value of pi
    printf("%.*lf\n",n,pi); // * will get replaced by n which is the required precision

I think the accepted answer is great, but it seems many people have failed to grasp some fundamental points.

First, Scala's for comprehensions are equivalent to Haskell's do notation, and it is nothing more than a syntactic sugar for composition of multiple monadic operations. As this statement will most likely not help anyone who needs help, let's try again… :-)

Scala's for comprehensions is syntactic sugar for composition of multiple operations with map, flatMap and filter. Or foreach. Scala actually translates a for-expression into calls to those methods, so any class providing them, or a subset of them, can be used with for comprehensions.

First, let's talk about the translations. There are very simple rules:

1. This

   for(x <- c1; y <- c2; z <-c3) {...}
   

   is translated into

   c1.foreach(x => c2.foreach(y => c3.foreach(z => {...})))
   

2. This

   for(x <- c1; y <- c2; z <- c3) yield {...}
   

   is translated into

   c1.flatMap(x => c2.flatMap(y => c3.map(z => {...})))
   

3. This

   for(x <- c; if cond) yield {...}
   

   is translated on Scala 2.7 into

   c.filter(x => cond).map(x => {...})
   

   or, on Scala 2.8, into

   c.withFilter(x => cond).map(x => {...})
   

   with a fallback into the former if method withFilter is not available but filter is. Please see the section below for more information on this.

4. This

   for(x <- c; y = ...) yield {...}
   

   is translated into

   c.map(x => (x, ...)).map((x,y) => {...})
   

When you look at very simple for comprehensions, the map/foreach alternatives look, indeed, better. Once you start composing them, though, you can easily get lost in parenthesis and nesting levels. When that happens, for comprehensions are usually much clearer.

I'll show one simple example, and intentionally omit any explanation. You can decide which syntax was easier to understand.

l.flatMap(sl => sl.filter(el => el > 0).map(el => el.toString.length))

or

for {
  sl <- l
  el <- sl
  if el > 0
} yield el.toString.length

withFilter

Scala 2.8 introduced a method called withFilter, whose main difference is that, instead of returning a new, filtered, collection, it filters on-demand. The filter method has its behavior defined based on the strictness of the collection. To understand this better, let's take a look at some Scala 2.7 with List (strict) and Stream (non-strict):

scala> var found = false
found: Boolean = false

scala> List.range(1,10).filter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3
7
9

scala> found = false
found: Boolean = false

scala> Stream.range(1,10).filter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3

The difference happens because filter is immediately applied with List, returning a list of odds -- since found is false. Only then foreach is executed, but, by this time, changing found is meaningless, as filter has already executed.

In the case of Stream, the condition is not immediatelly applied. Instead, as each element is requested by foreach, filter tests the condition, which enables foreach to influence it through found. Just to make it clear, here is the equivalent for-comprehension code:

for (x <- List.range(1, 10); if x % 2 == 1 && !found) 
  if (x == 5) found = true else println(x)

for (x <- Stream.range(1, 10); if x % 2 == 1 && !found) 
  if (x == 5) found = true else println(x)

This caused many problems, because people expected the if to be considered on-demand, instead of being applied to the whole collection beforehand.

Scala 2.8 introduced withFilter, which is always non-strict, no matter the strictness of the collection. The following example shows List with both methods on Scala 2.8:

scala> var found = false
found: Boolean = false

scala> List.range(1,10).filter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3
7
9

scala> found = false
found: Boolean = false

scala> List.range(1,10).withFilter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3

This produces the result most people expect, without changing how filter behaves. As a side note, Range was changed from non-strict to strict between Scala 2.7 and Scala 2.8.

Yes, there is. This is a function I borrowed from a user on a different forums a a few years back, so I can't take credit for it.

//truncate a string only at a whitespace (by nogdog)
function truncate($text, $length) {
   $length = abs((int)$length);
   if(strlen($text) > $length) {
      $text = preg_replace("/^(.{1,$length})(\s.*|$)/s", '\\1...', $text);
   }
   return($text);
}

Note that it automatically adds ellipses, if you don't want that just use '\\1' as the second parameter for the preg_replace call.

You need to have better understanding of the python language and its standard library to translate the expression

cat "$filename": Reads the file cat "$filename" and dumps the content to stdout

|: pipe redirects the stdout from previous command and feeds it to the stdin of the next command

grep "something": Searches the regular expressionsomething plain text data file (if specified) or in the stdin and returns the matching lines.

cut -d'"' -f2: Splits the string with the specific delimiter and indexes/splices particular fields from the resultant list

Python Equivalent

cat "$filename"  | with open("$filename",'r') as fin:        | Read the file Sequentially
                 |     for line in fin:                      |   
-----------------------------------------------------------------------------------
grep 'something' | import re                                 | The python version returns
                 | line = re.findall(r'something', line)[0]  | a list of matches. We are only
                 |                                           | interested in the zero group
-----------------------------------------------------------------------------------
cut -d'"' -f2    | line = line.split('"')[1]                 | Splits the string and selects
                 |                                           | the second field (which is
                 |                                           | index 1 in python)

Combining

import re
with open("filename") as origin_file:
    for line in origin_file:
        line = re.findall(r'something', line)
        if line:
           line = line[0].split('"')[1]
        print line

Not quite, the AND has to be lower-case.

Java has built-in functions to get the basename and dirname for a given file path, but the function names are not so self-apparent.

import java.io.File;

public class JavaFileDirNameBaseName {
    public static void main(String[] args) {
    File theFile = new File("../foo/bar/baz.txt");
    System.out.println("Dirname: " + theFile.getParent());
    System.out.println("Basename: " + theFile.getName());
    }
}

This is similar to your original approach, and will use less space than unutbu's answer, but I suspect it will be slower.

>>> import numpy as np
>>> p = np.array([[1.5, 0], [1.4,1.5], [1.6, 0], [1.7, 1.8]])
>>> p
array([[ 1.5,  0. ],
       [ 1.4,  1.5],
       [ 1.6,  0. ],
       [ 1.7,  1.8]])
>>> nz = (p == 0).sum(1)
>>> q = p[nz == 0, :]
>>> q
array([[ 1.4,  1.5],
       [ 1.7,  1.8]])

By the way, your line p.delete() doesn't work for me - ndarrays don't have a .delete attribute.

I know it's not exactly what you're asking, but, for replacing a comma with a newline, this works great:

tr , '\n' < file

"Timeline (responsive)" snippet:

This looks very, very close to what your example shows. The bootstrap snippet linked below covers all the bases you are looking for. I've been considering it myself, with the same requirements you have ( especially responsiveness ). This morphs well between screen sizes and devices.

You can fork this and use it as a great starting point for your specific expectations:

• http://bootsnipp.com/snippets/featured/timeline-responsive

Here are two screenshots I took for you... wide and thin:

A little bit off topic maybe, but for modern browsers (IE9 and newer) you can use the css odd/even selectors to achieve want you want.

tr:nth-child(even) { /* your alt-row stuff */}
tr:nth-child(odd) { /* the other rows */ }

or

tr { /* all table rows */ }
tr:nth-child(even) { /* your alt-row stuff */}

You are using the correct syntax for binding to the document to listen for a click event for an element with id="test-element".

It's probably not working due to one of:

• Not using recent version of jQuery
• Not wrapping your code inside of DOM ready
• or you are doing something which causes the event not to bubble up to the listener on the document.

To capture events on elements which are created AFTER declaring your event listeners - you should bind to a parent element, or element higher in the hierarchy.

For example:

$(document).ready(function() {
    // This WILL work because we are listening on the 'document', 
    // for a click on an element with an ID of #test-element
    $(document).on("click","#test-element",function() {
        alert("click bound to document listening for #test-element");
    });

    // This will NOT work because there is no '#test-element' ... yet
    $("#test-element").on("click",function() {
        alert("click bound directly to #test-element");
    });

    // Create the dynamic element '#test-element'
    $('body').append('<div id="test-element">Click mee</div>');
});

In this example, only the "bound to document" alert will fire.

JSFiddle with jQuery 1.9.1

I have faced this problem and I made research and didn't get anything, so I was trying and finally, I knew the cause of this problem. the problem on the API, make sure you have a good variable name I used $start_date and it caused the problem, so I try $startdate and it works!

as well make sure you send all parameter that declare on API, for example, $startdate = $_POST['startdate']; $enddate = $_POST['enddate'];

you have to pass this two variable from the retrofit.

as well if you use date on SQL statement, try to put it inside '' like '2017-07-24'

I hope it helps you.

If your model is really "responsible" for the constants you should stick them there. You can create class methods to access them without creating a new object instance:

class Card < ActiveRecord::Base
  def self.colours
    ['white', 'blue']
  end
end

# accessible like this
Card.colours

Alternatively, you can create class variables and an accessor. This is however discouraged as class variables might act kind of surprising with inheritance and in multi-thread environments.

class Card < ActiveRecord::Base
  @@colours = ['white', 'blue'].freeze
  cattr_reader :colours
end

# accessible the same as above
Card.colours

The two options above allow you to change the returned array on each invocation of the accessor method if required. If you have true a truly unchangeable constant, you can also define it on the model class:

class Card < ActiveRecord::Base
  COLOURS = ['white', 'blue'].freeze
end

# accessible as
Card::COLOURS

You could also create global constants which are accessible from everywhere in an initializer like in the following example. This is probably the best place, if your colours are really global and used in more than one model context.

# put this into config/initializers/my_constants.rb
COLOURS = ['white', 'blue'].freeze

# accessible as a top-level constant this time
COLOURS

Note: when we define constants above, often we want to freeze the array. That prevents other code from later (inadvertently) modifying the array by e.g. adding a new element. Once an object is frozen, it can't be changed anymore.

Configure XCode project settings, it can solve your problem.

The fastest and easiest way:

public static boolean deleteFolder(File removableFolder) {
        File[] files = removableFolder.listFiles();
        if (files != null && files.length > 0) {
            for (File file : files) {
                boolean success;
                if (file.isDirectory())
                    success = deleteFolder(file);
                else success = file.delete();
                if (!success) return false;
            }
        }
        return removableFolder.delete();
}

Java has primitive types, objects and arrays and that's it. No typedefs.

You can use:

$(window).unload(function() {
    //do something
}

Unload() is deprecated in jQuery version 1.8, so if you use jQuery > 1.8 you can use even beforeunload instead.

The beforeunload event fires whenever the user leaves your page for any reason.

$(window).on("beforeunload", function() { 
    return confirm("Do you really want to close?"); 
})

Source Browser window close event

You use the ajaxStop to execute code when the ajax are completed:

$(document).ajaxStop(function(){
  setTimeout("window.location = 'otherpage.html'",100);
});

A good rule of thumb is ".h files should have declarations [potentially] used by multiple source files, but no code that gets run."

<?php
$arr = array(0 => array("id"=>1,"name"=>"cat 1"),
             1 => array("id"=>2,"name"=>"cat 2"),
             2 => array("id"=>3,"name"=>"cat 1")
);
$arr = array_filter($arr, function($ar) {
   return ($ar['name'] == 'cat 1');
   //return ($ar['name'] == 'cat 1' AND $ar['id'] == '3');// you can add multiple conditions
});

echo "<pre>";
print_r($arr);

?>

Ref: http://php.net/manual/en/function.array-filter.php

Box Sizing
set the box sizing to border box box-sizing: border-box; and set the width to 100% and a fixed width for the border then add a min-width so for a small screen the border won't overtake the whole screen

FWIW, this config worked for me:

location = /logpush.html {
  if ($request_method = POST) {
    access_log /var/log/nginx/push.log push_requests;
    proxy_pass $scheme://127.0.0.1/logsink;
    break;
  }   
  return 200 $scheme://$host/serviceup.html;
}   
#
location /logsink {
  return 200;
}

The setting for the list throttle

• Open the SharePoint Central Administration,
• go to Application Management --> Manage Web Applications
• Click to select the web application that hosts your list (eg. SharePoint - 80)
• At the Ribbon, select the General Settings and select Resource Throttling
• Then, you can see the 5000 List View Threshold limit and you can edit the value you want.
• Click OK to save it.

I like Tri Q's answer, but those value converters are a pain to use. PaulB did it with an event handler, but that's also unnecessary. Here's a pure XAML solution:

<ContentControl Content="{Binding YourChoices}">
    <ContentControl.ContentTemplate>
        <DataTemplate>
            <Grid>
                <ComboBox x:Name="cb" ItemsSource="{Binding}"/>
                <TextBlock x:Name="tb" Text="Select Something" IsHitTestVisible="False" Visibility="Hidden"/>
            </Grid>
            <DataTemplate.Triggers>
                <Trigger SourceName="cb" Property="SelectedItem" Value="{x:Null}">
                    <Setter TargetName="tb" Property="Visibility" Value="Visible"/>
                </Trigger>
            </DataTemplate.Triggers>
        </DataTemplate>
    </ContentControl.ContentTemplate> 
</ContentControl>

You can use the below code to run test cases in Chrome using Selenium WebDriver:

import java.io.IOException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class ChromeTest {

    /**
     * @param args
     * @throws InterruptedException
     * @throws IOException
     */
    public static void main(String[] args) throws InterruptedException, IOException {
        // Telling the system where to find the Chrome driver
        System.setProperty(
                "webdriver.chrome.driver",
                "E:/chromedriver_win32/chromedriver.exe");

        WebDriver webDriver = new ChromeDriver();

        // Open google.com
        webDriver.navigate().to("http://www.google.com");

        String html = webDriver.getPageSource();

        // Printing result here.
        System.out.println(html);

        webDriver.close();
        webDriver.quit();
    }
}

I modified Brad Larson's Code. It will aspect fill the image in given rect.

-(UIImage*) scaleAndCropToSize:(CGSize)newSize;
{
    float ratio = self.size.width / self.size.height;

    UIGraphicsBeginImageContext(newSize);

    if (ratio > 1) {
        CGFloat newWidth = ratio * newSize.width;
        CGFloat newHeight = newSize.height;
        CGFloat leftMargin = (newWidth - newHeight) / 2;
        [self drawInRect:CGRectMake(-leftMargin, 0, newWidth, newHeight)];
    }
    else {
        CGFloat newWidth = newSize.width;
        CGFloat newHeight = newSize.height / ratio;
        CGFloat topMargin = (newHeight - newWidth) / 2;
        [self drawInRect:CGRectMake(0, -topMargin, newSize.width, newSize.height/ratio)];
    }

    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}

I also had this issue. Tried different things. But finally

conda install opencv

worked for me.

The line below throws exception if the key does not exists.

IEnumerable<string> headerValues = request.Headers.GetValues("MyCustomID");

Work around :

Include System.Linq;

IEnumerable<string> headerValues;
var userId = string.Empty;

     if (request.Headers.TryGetValues("MyCustomID", out headerValues))
     {
         userId = headerValues.FirstOrDefault();
     }           

For Swift 5 just the same as Swift 4

 let button = UIButton()
 button.frame = CGRect(x: self.view.frame.size.width - 60, y: 60, width: 50, height: 50)
 button.backgroundColor = UIColor.red
 button.setTitle("Name your Button ", for: .normal)
 button.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
 self.view.addSubview(button)

 @objc func buttonAction(sender: UIButton!) {
    print("Button tapped")
 }

If you want to display at row=159220

row=159220

#To display in a table format
display(res.loc[row:row])
display(res.iloc[row:row+1])

#To display in print format
display(res.loc[row])
display(res.iloc[row])

The code from Alex works great. Just note that when you use request.getParameter you must use a request dispatcher

//Pass results back to the client
RequestDispatcher dispatcher =   getServletContext().getRequestDispatcher("TestPages/ServiceServlet.jsp");
dispatcher.forward(request, response);

I am not sure and not really trust $_SERVER['HTTP_HOST'] because it depend on header from client. In another way, if a domain requested by client is not mine one, they will not getting into my site because DNS and TCP/IP protocol point it to the correct destination. However I don't know if possible to hijack the DNS, network or even Apache server. To be safe, I define host name in environment and compare it with $_SERVER['HTTP_HOST'].

Add SetEnv MyHost domain.com in .htaccess file on root and add ths code in Common.php

if (getenv('MyHost')!=$_SERVER['HTTP_HOST']) {
  header($_SERVER['SERVER_PROTOCOL'].' 400 Bad Request');
  exit();
}

I include this Common.php file in every php page. This page doing anything required for each request like session_start(), modify session cookie and reject if post method come from different domain.

For those who were having trouble parsing other answers:

eval "for _,k in ipairs(redis.call('keys','key:*:pattern')) do redis.call('del',k) end" 0

Replace key:*:pattern with your own pattern and enter this into redis-cli and you are good to go.

I'm a little surprised it doesn't just do that. Could there another element inside the div that has a width set to something greater than 250?

jQuery has few functions which work with text, if you use text() one, it will do the job for you:

$("#regTitle").text("Hello World");

Also, you can use html() instead, if you have any html tag...

df.select_dtypes(exclude = ['object'])

Update:

df.select_dtypes(include= np.number)

or with new version of panda

 df.select_dtypes('number')

Personally I would avoid iframes and go with an embed tag to create the view in the mouseover box.

<embed src="http://www.btf-internet.com" width="600" height="400" />

You should use raw_input to take a string input. then use islower method of str object.

s = raw_input('Type a word')
l = []
for c in s.strip():
    if c.islower():
        print c
        l.append(c)
print 'Total number of lowercase letters: %d'%(len(l) + 1)

Just do -

dir(s)

and you will find islower and other attributes of str

Building further on user Nick's answer and user hitautodestruct's plugin on JSBin, I've created a similar jQuery plugin which retrieves both width and height and returns an object containing these values.

It can be found here: http://jsbin.com/ikogez/3/

Update

I've completely redesigned this tiny little plugin as it turned out that the previous version (mentioned above) wasn't really usable in real life environments where a lot of DOM manipulation was happening.

This is working perfectly:

/**
 * getSize plugin
 * This plugin can be used to get the width and height from hidden elements in the DOM.
 * It can be used on a jQuery element and will retun an object containing the width
 * and height of that element.
 *

 */
$.fn.getSize = function() {    
    var $wrap = $("<div />").appendTo($("body"));
    $wrap.css({
        "position":   "absolute !important",
        "visibility": "hidden !important",
        "display":    "block !important"
    });

    $clone = $(this).clone().appendTo($wrap);

    sizes = {
        "width": $clone.width(),
        "height": $clone.height()
    };

    $wrap.remove();

    return sizes;
};

You often want to use wildcards with Class. For instance, Class<? extends JComponent>, would allow you to specify that the class is some subclass of JComponent. If you've retrieved the Class instance from Class.forName, then you can use Class.asSubclass to do the cast before attempting to, say, construct an instance.

Not sure if this is new in Xcode 5 or not, but you can now open the Size Inspector through Interface Builder and set an inset there. That'll prevent you from having to write custom code to do this for you and should drastically increase the speed at which you find the proper offsets.

The answers here are definitely suitable but they are a bit slow because they require looping through the whitelist for every property in the object. The solution below is much quicker for large datasets because it only loops through the whitelist once:

const data = {
  allowed1: 'blah',
  allowed2: 'blah blah',
  notAllowed: 'woah',
  superSensitiveInfo: 'whooooah',
  allowed3: 'bleh'
};

const whitelist = ['allowed1', 'allowed2', 'allowed3'];

function sanitize(data, whitelist) {
    return whitelist.reduce(
      (result, key) =>
        data[key] !== undefined
          ? Object.assign(result, { [key]: data[key] })
          : result,
      {}
    );
  }

  sanitize(data, whitelist)

Try this configuration. It worked for me:

</plugin>

A)

Object* o;
o = new Object();

`` B)

Object* o = new Object();

I think A and B has no difference. In both the cases o is a pointer to class Object. statement new Object() creates an object of class Object from heap memory. Assignment statement assigns the address of allocated memory to pointer o.

One thing I would like to mention that size of allocated memory from heap is always the sizeof(Object) not sizeof(Object) + sizeof(void *).

A bit late to answer the question. But,

If it's a MySQL database

should $doctrine_record_object->id work if AUTO_INCREMENT is defined in database and in your table definition.

Here is a guide to JSZIP to create ZIP files by JavaScript. To download files you need to have filesaver.js, You can include those libraries by:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.4/jszip.min.js"  type="text/javascript"></script>
<script type="text/javascript" src="https://fastcdn.org/FileSaver.js/1.1.20151003/FileSaver.js" ></script>

Now copy this code and this code will download a zip file with a file hello.txt having content Hello World. If everything thing works fine, this will download a file.

<script type="text/javascript">
    var zip = new JSZip();
    zip.file("Hello.txt", "Hello World\n");
    zip.generateAsync({type:"blob"})
    .then(function(content) {
        // see FileSaver.js
        saveAs(content, "file.zip");
    });
</script>

Now let's get in to deeper. Create an instance of JSZip.

var zip = new JSZip();

Add a file with a Hello World text:

zip.file("hello.txt", "Hello World\n");

Download the filie with name archive.zip

zip.generateAsync({type:"blob"}).then(function(zip) {
    saveAs(zip, "archive.zip");
});

All the following is about getting binary strings from array buffers

I'd recommend not to use

var binaryString = String.fromCharCode.apply(null, new Uint8Array(arrayBuffer));

because it

1. crashes on big buffers (somebody wrote about "magic" size of 246300 but I got Maximum call stack size exceeded error on 120000 bytes buffer (Chrome 29))
2. it has really poor performance (see below)

If you exactly need synchronous solution use something like

var
  binaryString = '',
  bytes = new Uint8Array(arrayBuffer),
  length = bytes.length;
for (var i = 0; i < length; i++) {
  binaryString += String.fromCharCode(bytes[i]);
}

it is as slow as the previous one but works correctly. It seems that at the moment of writing this there is no quite fast synchronous solution for that problem (all libraries mentioned in this topic uses the same approach for their synchronous features).

But what I really recommend is using Blob + FileReader approach

function readBinaryStringFromArrayBuffer (arrayBuffer, onSuccess, onFail) {
  var reader = new FileReader();
  reader.onload = function (event) {
    onSuccess(event.target.result);
  };
  reader.onerror = function (event) {
    onFail(event.target.error);
  };
  reader.readAsBinaryString(new Blob([ arrayBuffer ],
    { type: 'application/octet-stream' }));
}

the only disadvantage (not for all) is that it is asynchronous. And it is about 8-10 times faster then previous solutions! (Some details: synchronous solution on my environment took 950-1050 ms for 2.4Mb buffer but solution with FileReader had times about 100-120 ms for the same amount of data. And I have tested both synchronous solutions on 100Kb buffer and they have taken almost the same time, so loop is not much slower the using 'apply'.)

BTW here: How to convert ArrayBuffer to and from String author compares two approaches like me and get completely opposite results (his test code is here) Why so different results? Probably because of his test string that is 1Kb long (he called it "veryLongStr"). My buffer was a really big JPEG image of size 2.4Mb.

What about calling the buster repeatedly as well? This'll create a race condition, but one may hope that the buster comes out on top:

(function() {
    if(top !== self) {
        top.location.href = self.location.href;
        setTimeout(arguments.callee, 0);
    }
})();

UPDATE: As of Bootstrap 3.0, the input-* classes described below for setting the width of input elements were removed. Instead use the col-* classes to set the width of input elements. Examples are provided in the documentation.

In Bootstrap 2.3, you'd use the input classes for setting the width.

<textarea class="input-mini"></textarea>
<textarea class="input-small"></textarea>
<textarea class="input-medium"></textarea>
<textarea class="input-large"></textarea>
<textarea class="input-xlarge"></textarea>
<textarea class="input-xxlarge"></textarea>?
<textarea class="input-block-level"></textarea>?

Do a find for "Control sizing" for examples in the documentation.

But for height I think you'd still use the rows attribute.

Setting the content type and the content disposition as described above produces wildly varying results with different browsers:

IE8: SaveAs dialog as desired, and Excel as the default app. 100% good.

Firefox: SaveAs dialog does show up, but Firefox has no idea it is a spreadsheet. Suggests opening it with Visual Studio! 50% good

Chrome: the hints are fully ignored. The CSV data is shown in the browser. 0% good.

Of course in all of these cases I'm referring to the browsers as they come out of they box, with no customization of the mime/application mappings.

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

Regular expressions are great, but why not just make sure it's a number before trying to do something with it?

function addemup() {
var n1 = document.getElementById("num1");
var n2 = document.getElementById("num2");
sum = Number(n1.value) + Number(n2.value);
    if(Number(sum)) {
        alert(sum);
        } else {
            alert("Numbers only, please!");
        };

For repeating the last command in python, you can use <Alt + n> in windows

Firstly, I am not an authority on WebClient vs. HttpClient, specifically. Secondly, from your comments above, it seems to suggest that WebClient is Sync ONLY whereas HttpClient is both.

I did a quick performance test to find how WebClient (Sync calls), HttpClient (Sync and Async) perform. and here are the results.

I see that as a huge difference when thinking for future, i.e. long running processes, responsive GUI, etc. (add to the benefit you suggest by framework 4.5 - which in my actual experience is hugely faster on IIS)

If you're using homebrew:

brew services restart memcached

This is a solution that means that as you add new stored procedures to the schema, users can execute them without having to call grant execute on the new stored procedure:

IF  EXISTS (SELECT * FROM sys.database_principals WHERE name = N'asp_net')
DROP USER asp_net
GO

IF  EXISTS (SELECT * FROM sys.database_principals 
WHERE name = N'db_execproc' AND type = 'R')
DROP ROLE [db_execproc]
GO

--Create a database role....
CREATE ROLE [db_execproc] AUTHORIZATION [dbo]
GO

--...with EXECUTE permission at the schema level...
GRANT EXECUTE ON SCHEMA::dbo TO db_execproc;
GO

--http://www.patrickkeisler.com/2012/10/grant-execute-permission-on-all-stored.html
--Any stored procedures that are created in the dbo schema can be 
--executed by users who are members of the db_execproc database role

--...add a user e.g. for the NETWORK SERVICE login that asp.net uses
CREATE USER asp_net 
FOR LOGIN [NT AUTHORITY\NETWORK SERVICE] 
WITH DEFAULT_SCHEMA=[dbo]
GO

--...and add them to the roles you need
EXEC sp_addrolemember N'db_execproc', 'asp_net';
EXEC sp_addrolemember N'db_datareader', 'asp_net';
EXEC sp_addrolemember N'db_datawriter', 'asp_net';
GO

plt.errorbar can be used to plot x, y, error data (as opposed to the usual plt.plot)

import matplotlib.pyplot as plt
import numpy as np

x = np.array([1, 2, 3, 4, 5])
y = np.power(x, 2) # Effectively y = x**2
e = np.array([1.5, 2.6, 3.7, 4.6, 5.5])

plt.errorbar(x, y, e, linestyle='None', marker='^')

plt.show()

plt.errorbar accepts the same arguments as plt.plot with additional yerr and xerr which default to None (i.e. if you leave them blank it will act as plt.plot).

The best option (for my of course) is do it yourserfl. It means you can modify programattly all parts of the SOAP message

Binding binding = prov.getBinding();
   List<Handler> handlerChain = binding.getHandlerChain();
    handlerChain.add( new ModifyMessageHandler() );
    binding.setHandlerChain( handlerChain ); 

And the ModifyMessageHandler source could be

@Override
public boolean handleMessage( SOAPMessageContext context )
{
    SOAPMessage msg = context.getMessage(); 
    try
    {

        SOAPEnvelope envelope = msg.getSOAPPart().getEnvelope();
        SOAPHeader header = envelope.addHeader();
        SOAPElement ele = header.addChildElement( new QName( "http://uri", "name_of_header" ) );
        ele.addTextNode( "value_of_header" );
        ele = header.addChildElement( new QName( "http://uri", "name_of_header" ) );
        ele.addTextNode( "value_of_header" );
        ele = header.addChildElement( new QName( "http://uri", "name_of_header" ) );
        ele.addTextNode( "value_of_header" );

...

I hope this helps you

You can use this code from firebase github samples ..

You don't need to edit in layout files ... just make a new class "BaseActivity"

package com.example;

import android.app.ProgressDialog;
import android.support.annotation.VisibleForTesting;
import android.support.v7.app.AppCompatActivity;


public class BaseActivity extends AppCompatActivity {

    @VisibleForTesting
    public ProgressDialog mProgressDialog;

    public void showProgressDialog() {
        if (mProgressDialog == null) {
            mProgressDialog = new ProgressDialog(this);
            mProgressDialog.setMessage("Loading ...");
            mProgressDialog.setIndeterminate(true);
        }

        mProgressDialog.show();
    }


    public void hideProgressDialog() {
        if (mProgressDialog != null && mProgressDialog.isShowing()) {
            mProgressDialog.dismiss();
        }
    }

    @Override
    public void onStop() {
        super.onStop();
        hideProgressDialog();
    }

}

In your Activity that you want to use the progress dialog ..

public class MyActivity extends BaseActivity

Before/After the function that take time

showProgressDialog();
.... my code that take some time
showProgressDialog();

The anaconda installer adds a line in your ~/.bash_profile script that prepends the anaconda bin directory to your $PATH environment variable. Deleting the anaconda directory should be all you need to do, but it's good housekeeping to remove this line from your setup script too.

For Android Studio 3.4.1

Simply open the gradle tab (can be located on the right) and right-click on the parent in the list (should be called "Android"), then select "Refresh dependencies".

This should resolve your issue.

overflow-y : scroll;
overflow-x : hidden;

height is optional

Since LocalDateSerializer turns it into "[year,month,day]" (a json array) rather than "year-month-day" (a json string) by default, and since I don't want to require any special ObjectMapper setup (you can make LocalDateSerializer generate strings if you disable SerializationFeature.WRITE_DATES_AS_TIMESTAMPS but that requires additional setup to your ObjectMapper), I use the following:

imports:

import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer;

code:

// generates "yyyy-MM-dd" output
@JsonSerialize(using = ToStringSerializer.class)
// handles "yyyy-MM-dd" input just fine (note: "yyyy-M-d" format will not work)
@JsonDeserialize(using = LocalDateDeserializer.class)
private LocalDate localDate;

And now I can just use new ObjectMapper() to read and write my objects without any special setup.

There is this MarkerClusterer client side utility available for google Map as specified here on Google Map developer Articles, here is brief on what's it's usage:

There are many approaches for doing what you asked for:

• Grid based clustering
• Distance based clustering
• Viewport Marker Management
• Fusion Tables
• Marker Clusterer
• MarkerManager

You can read about them on the provided link above.

Marker Clusterer uses Grid Based Clustering to cluster all the marker wishing the grid. Grid-based clustering works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.

Before Clustering

After Clustering

I hope this is what you were looking for & this will solve your problem :)

If the user clicks Cancel, a zero-length string is returned. You can't differentiate this from entering an empty string. You can however make your own custom InputBox class...

EDIT to properly differentiate between empty string and cancel, according to this answer.

Your example

Private Sub test()
    Dim result As String
    result = InputBox("Enter Date MM/DD/YYY", "Date Confirmation", Now)
    If StrPtr(result) = 0 Then
        MsgBox ("User canceled!")
    ElseIf result = vbNullString Then
        MsgBox ("User didn't enter anything!")
    Else
        MsgBox ("User entered " & result)
    End If
End Sub

Would tell the user they canceled when they delete the default string, or they click cancel.

See http://msdn.microsoft.com/en-us/library/6z0ak68w(v=vs.90).aspx

CREATE TABLE sometable (t TIMESTAMP, d DATE);
INSERT INTO sometable SELECT '2011/05/26 09:00:00';
UPDATE sometable SET d = t; -- OK
-- UPDATE sometable SET d = t::date; OK
-- UPDATE sometable SET d = CAST (t AS date); OK
-- UPDATE sometable SET d = date(t); OK
SELECT * FROM sometable ;
          t          |     d      
---------------------+------------
 2011-05-26 09:00:00 | 2011-05-26
(1 row)

Another test kit:

SELECT pg_catalog.date(t) FROM sometable;
    date    
------------
 2011-05-26
(1 row)

SHOW datestyle ;

Use the -isEqualToString: method to compare the value of two strings. Using the C == operator will simply compare the addresses of the objects.

if ([category isEqualToString:@"Some String"])
{
    // Do stuff...
}

Autowiring Property Values into Spring Beans:

Most people know that you can use @Autowired to tell Spring to inject one object into another when it loads your application context. A lesser known nugget of information is that you can also use the @Value annotation to inject values from a property file into a bean’s attributes. see this post for more info...

You may also use the jQuery context parameter. Link to docs

Selector Context

By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function

Therefore you could also have:

success: function(data){
    var oneval = $('#one',data).text();
    var subval = $('#sub',data).text();
}

I've backported the three Material Design progress drawables to Android 4.0, which can be used as a drop-in replacement for regular ProgressBar, with exactly the same appearance.

These drawables also backported the tinting APIs (and RTL support), and uses ?colorControlActivated as the default tint. A MaterialProgressBar widget which extends ProgressBar has also been introduced for convenience.

DreaminginCodeZH/MaterialProgressBar

This project has also been adopted by afollestad/material-dialogs for progress dialog.

On Android 4.4.4:

On Android 5.1.1:

From the manual:

@

Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" .... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

To reverse rails generate, use rails destroy:

Randall, here are the VB expressions I found to work in SSRS to obtain the first and last days of any month, using the current month as a reference:

First day of last month:

=dateadd("m",-1,dateserial(year(Today),month(Today),1)) 

First day of this month:

=dateadd("m",0,dateserial(year(Today),month(Today),1)) 

First day of next month:

=dateadd("m",1,dateserial(year(Today),month(Today),1)) 

Last day of last month:

=dateadd("m",0,dateserial(year(Today),month(Today),0))

Last day of this month:

=dateadd("m",1,dateserial(year(Today),month(Today),0))

Last day of next month:

=dateadd("m",2,dateserial(year(Today),month(Today),0))

The MSDN documentation for the VisualBasic DateSerial(year,month,day) function explains that the function accepts values outside the expected range for the year, month, and day parameters. This allows you to specify useful date-relative values. For instance, a value of 0 for Day means "the last day of the preceding month". It makes sense: that's the day before day 1 of the current month.

I am using lambda with Zappa; I am sending data with POST in json format:

My code for basic_lambda_pure.py is:

import time
import requests
import json
def my_handler(event, context):
    print("Received event: " + json.dumps(event, indent=2))
    print("Log stream name:", context.log_stream_name)
    print("Log group name:",  context.log_group_name)
    print("Request ID:", context.aws_request_id)
    print("Mem. limits(MB):", context.memory_limit_in_mb)
    # Code will execute quickly, so we add a 1 second intentional delay so you can see that in time remaining value.
    print("Time remaining (MS):", context.get_remaining_time_in_millis())

    if event["httpMethod"] == "GET":
        hub_mode = event["queryStringParameters"]["hub.mode"]
        hub_challenge = event["queryStringParameters"]["hub.challenge"]
        hub_verify_token = event["queryStringParameters"]["hub.verify_token"]
        return {'statusCode': '200', 'body': hub_challenge, 'headers': 'Content-Type': 'application/json'}}

    if event["httpMethod"] == "post":

It´s eaiser to implement an random function on the enum.

public enum Via {
    A, B;

public static Via viaAleatoria(){
    Via[] vias = Via.values();
    Random generator = new Random();
    return vias[generator.nextInt(vias.length)];
    }
}

and then you call it from the class you need it like this

public class Guardia{
private Via viaActiva;

public Guardia(){
    viaActiva = Via.viaAleatoria();
}

Using Lambdas since java 8:

final String[][] data = new String[][] { new String[] { "2009.07.25 20:24", "Message A" },
        new String[] { "2009.07.25 20:17", "Message G" }, new String[] { "2009.07.25 20:25", "Message B" },
        new String[] { "2009.07.25 20:30", "Message D" }, new String[] { "2009.07.25 20:01", "Message F" },
        new String[] { "2009.07.25 21:08", "Message E" }, new String[] { "2009.07.25 19:54", "Message R" } };
String[][] out = Arrays.stream(data).sorted(Comparator.comparing(x -> x[1])).toArray(String[][]::new);

System.out.println(Arrays.deepToString(out));
    

Output:

[[2009.07.25 20:24, Message A], [2009.07.25 20:25, Message B], [2009.07.25 20:30, Message D], [2009.07.25 21:08, Message E], [2009.07.25 20:01, Message F], [2009.07.25 20:17, Message G], [2009.07.25 19:54, Message R]]

A similar case solved:

In our case, we wanted to set up linked servers using cnames and with the logins current security context.

All in order we checked that the service account running SQL Server had its' proper spns set and that the AD-object was trusted for delegation. But, while we were able to connect to the cname directly, we still had issues calling a linked server on its' cname: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

It took us far too long to realize that the cnames we used was for A-record, [A], that was set on a higher dns level, and not in its' own domain AD-level. Originally, we had the cname directing to [A].example.com and not (where it should) to: [A].domain.ad.example.com

Ofcourse we had these errors about anonymous logon.

I had the same problem, the solution is to add in build path/plugin the jar org.hamcrest.core_1xx, you can find it in eclipse/plugins.

Here's a method which allows you to register a Runnable to be executed once a particular web address has finished loading. We associate each Runnable with a corresponding URL String in a Map, and we use the WebView's getOriginalUrl() method to choose the appropriate callback.

package io.github.cawfree.webviewcallback;

        this.mWebView     = (WebView)this.findViewById(R.id.webView);
        this.mCallbackMap = new HashMap<>();
        // Define the custom WebClient. (Here I'm just suppressing security errors, since older Android devices struggle with TLS.)
        this.getWebView().setWebViewClient(new WebViewClient() {
            /** Handle when a request has been launched. */
            @Override public final void onPageFinished(final WebView pWebView, final String pUrl) {
                // Determine whether we're allowed to process the Runnable; if the page hadn't been redirected, or if we've finished redirection.
                if(pUrl.equals(pWebView.getOriginalUrl())) {
                    // Fetch the Runnable for the OriginalUrl.
                    final Runnable lRunnable = getCallbackMap().get(pWebView.getOriginalUrl());
                    // Is it valid?
                    if(lRunnable != null) { lRunnable.run(); }

            @Override public final void onReceivedSslError(final WebView pWebView, final SslErrorHandler pSslErrorHandler, final SslError pSslError) { pSslErrorHandler.proceed(); }
        });
        // Assert that we wish to visit Zonal's website.
        this.getWebView().loadUrl("http://www.zonal.co.uk/");
        // Align a Callback for Zonal; this will be serviced once the page has loaded.
        this.getCallbackMap().put("http://www.zonal.co.uk/", new Runnable() {     @Override public void run() { /* Do something. */ } });
    }

}

Another one liner for sign()

sign = lambda x: (1, -1)[x<0]

If you want it to return 0 for x = 0:

sign = lambda x: x and (1, -1)[x<0]

For Swift:

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.tableFooterView = UIView()
    }

With Java8 there is a default sort method on the List interface that will allow you to sort the collection if you provide a Comparator. You can easily sort the example in the question as follows:

testList.sort((a, b) -> Double.compare(b, a));

Note: the args in the lambda are swapped when passed in to Double.compare to ensure the sort is descending

Strange behaviour while debugging my app: require "active_support/notifications" (rdb:1) p ENV['RAILS_ENV'] "test" (rdb:1) p Rails.env "development"

I would say that you should stick to one or another (and preferably Rails.env)

Some might want certain class constants public while others private.

private keyword can be used to limit the scope of constants within the same swift file.

class MyClass {

struct Constants {

    static let testStr = "test"
    static let testStrLen = testStr.characters.count

    //testInt will not be accessable by other classes in different swift files
    private static let testInt = 1
}

func ownFunction()
{

    var newInt = Constants.testInt + 1

    print("Print testStr=\(Constants.testStr)")
}

}

Other classes will be able to access your class constants like below

class MyClass2
{

func accessOtherConstants()
{
    print("MyClass's testStr=\(MyClass.Constants.testStr)")
}

} 

Actually this is not really the same to import a variable with:

from file1 import x1
print(x1)

and

import file1
print(file1.x1)

Altough at import time x1 and file1.x1 have the same value, they are not the same variables. For instance, call a function in file1 that modifies x1 and then try to print the variable from the main file: you will not see the modified value.

UPD: updated to state Lifecycle.State.RESUMED. Thanks to @htafoya for that.

In 2019 with help of new support library 28+ or AndroidX you can simply use:

val isActivityInForeground = activity.lifecycle.currentState.isAtLeast(Lifecycle.State.RESUMED)

You can read more in the documenation to understand what happened under the hood.

I tend not to use compiler directives because they clutter things up quickly. One way to mitigate it if you really need them is to put them in a partial class and have your build ignore that .cs file when making the production version.

To get rid of the first column of NAs, you can do it with negative indexing (which removes indices from the R data set). For example:

output = matrix(1:6, 2, 3) # gives you a 2 x 3 matrix filled with the numbers 1 to 6

# output = 
#           [,1] [,2] [,3]
#     [1,]    1    3    5
#     [2,]    2    4    6

output = output[,-1] # this removes column 1 for all rows

# output = 
#           [,1] [,2]
#     [1,]    3    5
#     [2,]    4    6

So you can just add output = output[,-1]after the for loop in your original code.

Stab in the dark, but I was having the same exact issue. I solved it by deleting the project from my workspace (be careful not to delete from disk), and then re-imported the project and it worked fine. I think mine was caused by a bad windows shutdown (restarting windows correctly did not correct the issue). HTH.

• Date and Calendar are really the same fundamental concept (both represent an instant in time and are wrappers around an underlying long value).

• One could argue that Calendar is actually even more broken than Date is, as it seems to offer concrete facts about things like day of the week and time of day, whereas if you change its timeZone property, the concrete turns into blancmange! Neither objects are really useful as a store of year-month-day or time-of-day for this reason.

• Use Calendar only as a calculator which, when given Date and TimeZone objects, will do calculations for you. Avoid its use for property typing in an application.

• Use SimpleDateFormat together with TimeZone and Date to generate display Strings.

• If you're feeling adventurous use Joda-Time, although it is unnecessarily complicated IMHO and is soon to be superceded by the JSR-310 date API in any event.

• I have answered before that it is not difficult to roll your own YearMonthDay class, which uses Calendar under the hood for date calculations. I was downvoted for the suggestion but I still believe it is a valid one because Joda-Time (and JSR-310) are really so over-complicated for most use-cases.

PHP 5.3+ solution.

$new_time = DateTime::createFromFormat('h:i A', '01:00 PM');
$time_24 = $new_time->format('H:i:s');

Output: 13:00:00

Works great when formatting date is required. Check This Answer for details.

You'd better ping 127.0.0.1. Windows ping pauses for one second between pings so you if you want to sleep for 10 seconds, use

ping -n 11 127.0.0.1 > nul

This way you don't need to worry about unexpected early returns (say, there's no default route and the 123.45.67.89 is instantly known to be unreachable.)

  timeobj = datetime.datetime.strptime(my_time, '%Y-%m-%d %I:%M:%S')
  File "/usr/lib/python2.7/_strptime.py", line 335, in _strptime

ValueError: unconverted data remains:

In my case, the problem was an extra space in the input date string. So I used strip() and it started to work.

If you're able to upgrade to Postgresql 9.5, the jsonb_set command is available, as others have mentioned.

In each of the following SQL statements, I've omitted the where clause for brevity; obviously, you'd want to add that back.

Update name:

UPDATE test SET data = jsonb_set(data, '{name}', '"my-other-name"');

Replace the tags (as oppose to adding or removing tags):

UPDATE test SET data = jsonb_set(data, '{tags}', '["tag3", "tag4"]');

Replacing the second tag (0-indexed):

UPDATE test SET data = jsonb_set(data, '{tags,1}', '"tag5"');

Append a tag (this will work as long as there are fewer than 999 tags; changing argument 999 to 1000 or above generates an error. This no longer appears to be the case in Postgres 9.5.3; a much larger index can be used):

UPDATE test SET data = jsonb_set(data, '{tags,999999999}', '"tag6"', true);

Remove the last tag:

UPDATE test SET data = data #- '{tags,-1}'

Complex update (delete the last tag, insert a new tag, and change the name):

UPDATE test SET data = jsonb_set(
    jsonb_set(data #- '{tags,-1}', '{tags,999999999}', '"tag3"', true), 
    '{name}', '"my-other-name"');

It's important to note that in each of these examples, you're not actually updating a single field of the JSON data. Instead, you're creating a temporary, modified version of the data, and assigning that modified version back to the column. In practice, the result should be the same, but keeping this in mind should make complex updates, like the last example, more understandable.

In the complex example, there are three transformations and three temporary versions: First, the last tag is removed. Then, that version is transformed by adding a new tag. Next, the second version is transformed by changing the name field. The value in the data column is replaced with the final version.

Is there an easy way to view all methods which contain this comment? Some sort of menu option?

Yes, choose one of the following:

1. Go to Window ? Show View ? Tasks (Not TaskList). The new view will show up where the "Console" and "Problems" tabs are by default.

2. As mentioned elsewhere, you can see them next to the scroll bar as little blue rectangles if you have the source file in question open.

3. If you just want the // TODO Auto-generated method stub messages (rather than all // TODO messages) you should use the search function (Ctrl-F for ones in this file Search ? Java Search ? Search string for the ability to specify this workspace, that file, this project, etc.)

Regarding a NodeJS implementation, I have added a custom expiryTime field in the object I save in the HASH. Then after a specific period time, I clear the expired HASH entries by using the following code:

client.hgetall(HASH_NAME, function(err, reply) {
    if (reply) {
        Object.keys(reply).forEach(key => {
            if (reply[key] && JSON.parse(reply[key]).expiryTime < (new Date).getTime()) {
                client.hdel(HASH_NAME, key);
            }
        })
    }
});

UPDATE:

If you want to take advantage of Imagick (if it is installed on your server). Note: I didn't use Imagick's nature writeFile because I was having issues with it on my server. File put contents works just as well.

<?php
/**
 * 
 * Generate Thumbnail using Imagick class
 *  
 * @param string $img
 * @param string $width
 * @param string $height
 * @param int $quality
 * @return boolean on true
 * @throws Exception
 * @throws ImagickException
 */
function generateThumbnail($img, $width, $height, $quality = 90)
{
    if (is_file($img)) {
        $imagick = new Imagick(realpath($img));
        $imagick->setImageFormat('jpeg');
        $imagick->setImageCompression(Imagick::COMPRESSION_JPEG);
        $imagick->setImageCompressionQuality($quality);
        $imagick->thumbnailImage($width, $height, false, false);
        $filename_no_ext = reset(explode('.', $img));
        if (file_put_contents($filename_no_ext . '_thumb' . '.jpg', $imagick) === false) {
            throw new Exception("Could not put contents.");
        }
        return true;
    }
    else {
        throw new Exception("No valid image provided with {$img}.");
    }
}

// example usage
try {
    generateThumbnail('test.jpg', 100, 50, 65);
}
catch (ImagickException $e) {
    echo $e->getMessage();
}
catch (Exception $e) {
    echo $e->getMessage();
}
?>

I have been using this, just execute the function after you store the original image and use that location to create the thumbnail. Edit it to your liking...

function makeThumbnails($updir, $img, $id)
{
    $thumbnail_width = 134;
    $thumbnail_height = 189;
    $thumb_beforeword = "thumb";
    $arr_image_details = getimagesize("$updir" . $id . '_' . "$img"); // pass id to thumb name
    $original_width = $arr_image_details[0];
    $original_height = $arr_image_details[1];
    if ($original_width > $original_height) {
        $new_width = $thumbnail_width;
        $new_height = intval($original_height * $new_width / $original_width);
    } else {
        $new_height = $thumbnail_height;
        $new_width = intval($original_width * $new_height / $original_height);
    }
    $dest_x = intval(($thumbnail_width - $new_width) / 2);
    $dest_y = intval(($thumbnail_height - $new_height) / 2);
    if ($arr_image_details[2] == IMAGETYPE_GIF) {
        $imgt = "ImageGIF";
        $imgcreatefrom = "ImageCreateFromGIF";
    }
    if ($arr_image_details[2] == IMAGETYPE_JPEG) {
        $imgt = "ImageJPEG";
        $imgcreatefrom = "ImageCreateFromJPEG";
    }
    if ($arr_image_details[2] == IMAGETYPE_PNG) {
        $imgt = "ImagePNG";
        $imgcreatefrom = "ImageCreateFromPNG";
    }
    if ($imgt) {
        $old_image = $imgcreatefrom("$updir" . $id . '_' . "$img");
        $new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height);
        imagecopyresized($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
        $imgt($new_image, "$updir" . $id . '_' . "$thumb_beforeword" . "$img");
    }
}

The above function creates images with a uniform thumbnail size. If the image doesn't have the same dimensions as the specified thumbnail size (proportionally), it just has blackspace on the top and bottom.

This worked for me: To wrap the contents of the second file into a function, as follows:

firstFile.php

<?php
    include("secondFile.php");

    echoFunction("message");

secondFile.php

<?php
    function echoFunction($variable)
    {
        echo $variable;
    }

Try this SELECT DISTINCT 10 * ...

https://www.npmjs.com/package/typeof

Returns a string-representation of instanceof (the constructors name)

function instanceOf(object) {
  var type = typeof object

  if (type === 'undefined') {
    return 'undefined'
  }

  if (object) {
    type = object.constructor.name
  } else if (type === 'object') {
    type = Object.prototype.toString.call(object).slice(8, -1)
  }

  return type.toLowerCase()
}

instanceOf(false)                  // "boolean"
instanceOf(new Promise(() => {}))  // "promise"
instanceOf(null)                   // "null"
instanceOf(undefined)              // "undefined"
instanceOf(1)                      // "number"
instanceOf(() => {})               // "function"
instanceOf([])                     // "array"

Since the back button is a function of the browser, it can be difficult to change the default functionality. There are some work arounds though. Take a look at this article:

http://www.irt.org/script/311.htm

Typically, the need to disable the back button is a good indicator of a programming issue/flaw. I would look for an alternative method like setting a session variable or a cookie that stores whether the form has already been submitted.

this Code Make your textField Accept only Number

textField.lengthProperty().addListener((observable, oldValue, newValue) -> {
        if(newValue.intValue() > oldValue.intValue()){
            char c = textField.getText().charAt(oldValue.intValue());
            /** Check if the new character is the number or other's */
            if( c > '9' || c < '0'){
                /** if it's not number then just setText to previous one */
                textField.setText(textField.getText().substring(0,textField.getText().length()-1));
            }
        }
    });

This is another way to do it. I think maybe a little more general:

df.ix[:,-1]

Answer for a slightly different problem:

You have a sequence of raw unicode that was saved into a str variable:

s_str: str = "\x00\x01\x00\xc0\x01\x00\x00\x00\x04"

You need to be able to get the byte literal of that unicode (for struct.unpack(), etc.)

s_bytes: bytes = b'\x00\x01\x00\xc0\x01\x00\x00\x00\x04'

Solution:

s_new: bytes = bytes(s, encoding="raw_unicode_escape")

Reference (scroll up for standard encodings):

Python Specific Encodings

The code compiles ok for me. May be you have forgotten to add the import:

import android.app.AlertDialog;

Anyway, you have a good tutorial here.

Option 1 - Android PCAP

Limitation

Android PCAP should work so long as:

Your device runs Android 4.0 or higher (or, in theory, the few devices which run Android 3.2). Earlier versions of Android do not have a USB Host API

Option 2 - TcpDump

Limitation

Phone should be rooted

Option 3 - bitshark (I would prefer this)

Limitation

Phone should be rooted

Reason - the generated PCAP files can be analyzed in WireShark which helps us in doing the analysis.

Other Options without rooting your phone

1. tPacketCapture

https://play.google.com/store/apps/details?id=jp.co.taosoftware.android.packetcapture&hl=en

Advantages

Using tPacketCapture is very easy, captured packet save into a PCAP file that can be easily analyzed by using a network protocol analyzer application such as Wireshark.

2. You can route your android mobile traffic to PC and capture the traffic in the desktop using any network sniffing tool.

Now only I came across this situation and found some more interesting features around GROUP_CONCAT. I hope these details will make you feel interesting.

simple GROUP_CONCAT

SELECT GROUP_CONCAT(TaskName) 
FROM Tasks;

Result:

+------------------------------------------------------------------+
| GROUP_CONCAT(TaskName)                                           |
+------------------------------------------------------------------+
| Do garden,Feed cats,Paint roof,Take dog for walk,Relax,Feed cats |
+------------------------------------------------------------------+

GROUP_CONCAT with DISTINCT

SELECT GROUP_CONCAT(TaskName) 
FROM Tasks;

Result:

+------------------------------------------------------------------+
| GROUP_CONCAT(TaskName)                                           |
+------------------------------------------------------------------+
| Do garden,Feed cats,Paint roof,Take dog for walk,Relax,Feed cats |
+------------------------------------------------------------------+

GROUP_CONCAT with DISTINCT and ORDER BY

SELECT GROUP_CONCAT(DISTINCT TaskName ORDER BY TaskName DESC) 
FROM Tasks;

Result:

+--------------------------------------------------------+
| GROUP_CONCAT(DISTINCT TaskName ORDER BY TaskName DESC) |
+--------------------------------------------------------+
| Take dog for walk,Relax,Paint roof,Feed cats,Do garden |
+--------------------------------------------------------+

GROUP_CONCAT with DISTINCT and SEPARATOR

SELECT GROUP_CONCAT(DISTINCT TaskName SEPARATOR ' + ') 
FROM Tasks;

Result:

+----------------------------------------------------------------+
| GROUP_CONCAT(DISTINCT TaskName SEPARATOR ' + ')                |
+----------------------------------------------------------------+
| Do garden + Feed cats + Paint roof + Relax + Take dog for walk |
+----------------------------------------------------------------+

GROUP_CONCAT and Combining Columns

SELECT GROUP_CONCAT(TaskId, ') ', TaskName SEPARATOR ' ') 
FROM Tasks;

Result:

+------------------------------------------------------------------------------------+
| GROUP_CONCAT(TaskId, ') ', TaskName SEPARATOR ' ')                                 |
+------------------------------------------------------------------------------------+
| 1) Do garden 2) Feed cats 3) Paint roof 4) Take dog for walk 5) Relax 6) Feed cats |
+------------------------------------------------------------------------------------+

GROUP_CONCAT and Grouped Results Assume that the following are the results before using GROUP_CONCAT

here is a query that will show any queries that are blocking. I am not entirely sure if it will just show slow queries:

SELECT p.spid
,convert(char(12), d.name) db_name
, program_name
, convert(char(12), l.name) login_name
, convert(char(12), hostname) hostname
, cmd
, p.status
, p.blocked
, login_time
, last_batch
, p.spid
FROM      master..sysprocesses p
JOIN      master..sysdatabases d ON p.dbid =  d.dbid
JOIN      master..syslogins l ON p.sid = l.sid
WHERE     p.blocked = 0
AND       EXISTS (  SELECT 1
          FROM      master..sysprocesses p2
          WHERE     p2.blocked = p.spid )

You can add a new property of type IFormFile to your view model

public class CreatePost
{
   public string ImageCaption { set;get; }
   public string ImageDescription { set;get; }
   public IFormFile MyImage { set; get; }
}

and in your GET action method, we will create an object of this view model and send to the view.

public IActionResult Create()
{
   return View(new CreatePost());
}

Now in your Create view which is strongly typed to our view model, have a form tag which has the enctype attribute set to "multipart/form-data"

@model CreatePost
<form asp-action="Create" enctype="multipart/form-data">   

    <input asp-for="ImageCaption"/>
    <input asp-for="ImageDescription"/>
    <input asp-for="MyImage"/>

    <input type="submit"/>
</form>

And your HttpPost action to handle the form posting

[HttpPost]
public IActionResult Create(CreatePost model)
{
   var img = model.MyImage;
   var imgCaption = model.ImageCaption;

   //Getting file meta data
   var fileName = Path.GetFileName(model.MyImage.FileName);
   var contentType = model.MyImage.ContentType;

   // do something with the above data
   // to do : return something
}

If you want to upload the file to some directory in your app, you should use IHostingEnvironment to get the webroot path. Here is a working sample.

public class HomeController : Controller
{
    private readonly IHostingEnvironment hostingEnvironment;
    public HomeController(IHostingEnvironment environment)
    {
        hostingEnvironment = environment;
    }
    [HttpPost]
    public IActionResult Create(CreatePost model)
    {
        // do other validations on your model as needed
        if (model.MyImage != null)
        {
            var uniqueFileName = GetUniqueFileName(model.MyImage.FileName);
            var uploads = Path.Combine(hostingEnvironment.WebRootPath, "uploads");
            var filePath = Path.Combine(uploads,uniqueFileName);
            model.MyImage.CopyTo(new FileStream(filePath, FileMode.Create)); 

            //to do : Save uniqueFileName  to your db table   
        }
        // to do  : Return something
        return RedirectToAction("Index","Home");
    }
    private string GetUniqueFileName(string fileName)
    {
        fileName = Path.GetFileName(fileName);
        return  Path.GetFileNameWithoutExtension(fileName)
                  + "_" 
                  + Guid.NewGuid().ToString().Substring(0, 4) 
                  + Path.GetExtension(fileName);
    }
}

This will save the file to uploads folder inside wwwwroot directory of your app with a random file name generated using Guids ( to prevent overwriting of files with same name)

Here we are using a very simple GetUniqueName method which will add 4 chars from a guid to the end of the file name to make it somewhat unique. You can update the method to make it more sophisticated as needed.

Should you be storing the full url to the uploaded image in the database ?

No. Do not store the full url to the image in the database. What if tomorrow your business decides to change your company/product name from www.thefacebook.com to www.facebook.com ? Now you have to fix all the urls in the table!

What should you store ?

You should store the unique filename which you generated above(the uniqueFileName varibale we used above) to store the file name. When you want to display the image back, you can use this value (the filename) and build the url to the image.

For example, you can do this in your view.

@{
    var imgFileName = "cats_46df.png";
}
<img src="~/uploads/@imgFileName"  alt="my img"/>

I just hardcoded an image name to imgFileName variable and used that. But you may read the stored file name from your database and set to your view model property and use that. Something like

<img src="~/uploads/@Model.FileName"  alt="my img"/>

Storing the image to table

If you want to save the file as bytearray/varbinary to your database, you may convert the IFormFile object to byte array like this

private byte[] GetByteArrayFromImage(IFormFile file)
{
    using (var target = new MemoryStream())
    {
        file.CopyTo(target);
        return target.ToArray();
    }
}

Now in your http post action method, you can call this method to generate the byte array from IFormFile and use that to save to your table. the below example is trying to save a Post entity object using entity framework.

[HttpPost]
public IActionResult Create(CreatePost model)
{
    //Create an object of your entity class and map property values
    var post=new Post() { ImageCaption = model.ImageCaption };

    if (model.MyImage != null)
    {
       post.Image =  GetByteArrayFromImage(model.MyImage);
    }
    _context.Posts.Add(post);
    _context.SaveChanges();
    return RedirectToAction("Index","Home");
}

If you want to do it while keeping the user interaction on. In my case I am using (or rather misusing) isFocused

self.myField.inputView = UIView()

This way it will focus but keyboard won't show up.

By default session object is available on jsp page(implicit object). It will not available in normal POJO java class. You can get the reference of HttpSession object on Servelt by using HttpServletRequest

HttpSession s=request.getSession()
s.setAttribute("name","value");

You can get session on an ActionSupport based Action POJO class as follows

 ActionContext ctx= ActionContext.getContext();
   Map m=ctx.getSession();
   m.put("name", value);

look at: http://ohmjavaclasses.blogspot.com/2011/12/access-session-in-action-class-struts2.html

Following command worked out for me nicely. It gives you the OS name and version.

lsb_release -a

stdClass is not an anonymous class or anonymous object

Answers here includes expressions that stdClass is an anonymous class or even anonymous object. It's not a true.

stdClass is just a regular predefined class. You can check this using instanceof operator or function get_class. Nothing special goes here. PHP uses this class when casting other values to object.

In many cases where stdClass is used by the programmers the array is better option, because of useful functions and the fact that this usecase represents the data structure not a real object.

using prototype we can set directly to array class

Array.prototype.chunk = function(n) {_x000D_
  if (!this.length) {_x000D_
    return [];_x000D_
  }_x000D_
  return [this.slice(0, n)].concat(this.slice(n).chunk(n));_x000D_
};_x000D_
console.log([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15].chunk(5));

Some of the key differences are in the complexity requirements.

• A map requires O(log(N)) time for inserts and finds operations, as it's implemented as a Red-Black Tree data structure.

• An unordered_map requires an 'average' time of O(1) for inserts and finds, but is allowed to have a worst-case time of O(N). This is because it's implemented using Hash Table data structure.

So, usually, unordered_map will be faster, but depending on the keys and the hash function you store, can become much worse.

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

How to show images stored in numpy array with example (works in Jupyter notebook)

I know there are simpler answers but this one will give you understanding of how images are actually drawn from a numpy array.

Load example

from sklearn.datasets import load_digits
digits = load_digits()
digits.images.shape   #this will give you (1797, 8, 8). 1797 images, each 8 x 8 in size

Display array of one image

digits.images[0]
array([[ 0.,  0.,  5., 13.,  9.,  1.,  0.,  0.],
       [ 0.,  0., 13., 15., 10., 15.,  5.,  0.],
       [ 0.,  3., 15.,  2.,  0., 11.,  8.,  0.],
       [ 0.,  4., 12.,  0.,  0.,  8.,  8.,  0.],
       [ 0.,  5.,  8.,  0.,  0.,  9.,  8.,  0.],
       [ 0.,  4., 11.,  0.,  1., 12.,  7.,  0.],
       [ 0.,  2., 14.,  5., 10., 12.,  0.,  0.],
       [ 0.,  0.,  6., 13., 10.,  0.,  0.,  0.]])

Create empty 10 x 10 subplots for visualizing 100 images

import matplotlib.pyplot as plt
fig, axes = plt.subplots(10,10, figsize=(8,8))

Plotting 100 images

for i,ax in enumerate(axes.flat):
    ax.imshow(digits.images[i])

Result:

What does axes.flat do? It creates a numpy enumerator so you can iterate over axis in order to draw objects on them. Example:

import numpy as np
x = np.arange(6).reshape(2,3)
x.flat
for item in (x.flat):
    print (item, end=' ')

Could do something like this:

public static class ForEachExtensions
{
    public static void ForEachWithIndex<T>(this IEnumerable<T> enumerable, Action<T, int> handler)
    {
        int idx = 0;
        foreach (T item in enumerable)
            handler(item, idx++);
    }
}

public class Example
{
    public static void Main()
    {
        string[] values = new[] { "foo", "bar", "baz" };

        values.ForEachWithIndex((item, idx) => Console.WriteLine("{0}: {1}", idx, item));
    }
}

x or "default"

works best — i can even use a function call inline, without executing it twice or using extra variable:

self.lineEdit_path.setText( self.getDir(basepath) or basepath )

I use it when opening Qt's dialog.getExistingDirectory() and canceling, which returns empty string.

Use a Scanner and pass in the delimiter and the original string:

result = new Scanner(result).useDelimiter("\n").next();

To convert an integer to a string:

integer :: i    
character* :: s    
if (i.LE.9) then
     s=char(48+i)    
else if (i.GE.10) then
     s=char(48+(i/10))// char(48-10*(i/10)+i)    
endif

I'll add one thing: where I'm at we used to have a bunch of batch jobs that ran every night. However, we're moving away from that to using a client application scheduled in windows scheduled tasks that kicks off each job. There are (at least) three reasons for this:

1. We have some console programs that need to run every night as well. This way all scheduled tasks can be in one place. Of course, this creates a single point of failure, but if the console jobs don't run we're gonna lose a day's work the next day anyway.
2. The program that kicks off the jobs captures print messages and errors from the server and writes them to a common application log for all our batch processes. It makes logging from withing the sql jobs much simpler.
3. If we ever need to upgrade the server (and we are hoping to do this soon) we don't need to worry about moving the jobs over. Just re-point the application once.

It's a real short VB.Net app: I can post code if any one is interested.

I'd first split the file into few smaller ones like this

$ split --lines=50000 /path/to/large/file /path/to/output/file/prefix

and then grep on the resulting files.

on first button add the following.

onclick="window.location.href='Students.html';"

similarly do the rest 2 buttons.

<input type="button" value="Add Students" onclick="window.location.href='Students.html';"> 
<input type="button" value="Add Courses" onclick="window.location.href='Courses.html';"> 
<input type="button" value="Student Payments" onclick="window.location.href='Payments.html';">

I want to add that when using Windows you can use require './1.rb' if the script is run local or from a mapped network drive but when run from an UNC \\servername\sharename\folder path you need to use require_relative './1.rb'.

I don't mingle in the discussion which to use for other reasons.

As stated on http://en.wikipedia.org/wiki/Logarithm:

logb(x) = logk(x) / logk(b)

Which means that:

log2(x) = log10(x) / log10(2)

1 - (change) is bound to the HTML onchange event. The documentation about HTML onchange says the following :

Execute a JavaScript when a user changes the selected option of a <select> element

Source : https://www.w3schools.com/jsref/event_onchange.asp

2 - As stated before, (ngModelChange) is bound to the model variable binded to your input.

So, my interpretation is :

• (change) triggers when the user changes the input
• (ngModelChange) triggers when the model changes, whether it's consecutive to a user action or not

This gives capital Letters to all major words

library(lettercase)
xString = str_title_case(xString)

Something like this in your form main. Double click the form in the visual editor to create the form load event.

 Timer Clock=new Timer();
 Clock.Interval=2700000; // not sure if this length of time will work 
 Clock.Start();
 Clock.Tick+=new EventHandler(Timer_Tick);

Then add an event handler to do something when the timer fires.

  public void Timer_Tick(object sender,EventArgs eArgs)
  {
    if(sender==Clock)
    {
      // do something here      
    }
  }

I'm using a minSdkVersion 16 and targetSdkVersion 23.
The following is working for me, it uses

ContextCompat.getDrawable(context, R.drawable.drawable);

Instead of using:

layout.setBackgroundResource(R.drawable.ready);

Rather use:

layout.setBackground(ContextCompat.getDrawable(this, R.drawable.ready));

getActivity() is used in a fragment, if calling from a activity use this.

I have used a syntax like this before:

$(ProjectDir)..\headers

or

..\headers

As other have pointed out, the starting directory is the one your project file is in(vcproj or vcxproj), not where your main code is located.

if you get this error "Value does not fall within the expected range" in this line:

SPFolder myLibrary = oWeb.Folders[documentLibraryName];

use instead this to fix the error:

SPFolder myLibrary = oWeb.GetList(URL OR NAME).RootFolder;

Use always URl to get Lists or others because they are unique, names are not the best way ;)

See the answer at: http://omappedia.org/wiki/Android_eMMC_Booting#Modifying_.IMG_Files

First you need to "uncompress" userdata.img with simg2img, then you can mount it via the loop device.

Here is something else interesting you can do. Define a function to call just before each ajax call. Also assign a function to call after each ajax call is complete. The first function will set the wait cursor and the second will clear it. They look like the following:

$(document).ajaxComplete(function(event, request, settings) {
    $('*').css('cursor', 'default');
  });

function waitCursor() {
    $('*').css('cursor', 'progress');
  }

I'm not familiar with paramiko, but this may work:

ssh_stdin.write('input value')
ssh_stdin.flush()

For information on stdin:

http://docs.python.org/library/sys.html?highlight=stdin#sys.stdin

You simply cannot. DataFrames, same as other distributed data structures, are not iterable and can be accessed using only dedicated higher order function and / or SQL methods.

You can of course collect

for row in df.rdd.collect():
    do_something(row)

or convert toLocalIterator

for row in df.rdd.toLocalIterator():
    do_something(row)

and iterate locally as shown above, but it beats all purpose of using Spark.

No need for a library. jQuery used this script for a while, btw.

Example code:

a = pd.Series([1,2,3,4], index=[7,2,8,9])
b = pd.Series([5,6,7,8], index=[7,2,8,9])
data = pd.DataFrame({'a': a,'b':b, 'idx_col':a.index})

Pandas allows you to create a DataFrame from a dict with Series as the values and the column names as the keys. When it finds a Series as a value, it uses the Series index as part of the DataFrame index. This data alignment is one of the main perks of Pandas. Consequently, unless you have other needs, the freshly created DataFrame has duplicated value. In the above example, data['idx_col'] has the same data as data.index.

I solved it doing

run devenv /resetuserdata

in this path:

[x64] C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE

I assume that in x86 it works in this path:

[x86] C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE

Or since Objective C is just C with some OO layer on top you can use the posix conterparts:

int execl(const char *path, const char *arg0, ..., const char *argn, (char *)0);
int execle(const char *path, const char *arg0, ..., const char *argn, (char *)0, char *const envp[]);
int execlp(const char *file, const char *arg0, ..., const char *argn, (char *)0);
int execlpe(const char *file, const char *arg0, ..., const char *argn, (char *)0, char *const envp[]);
int execv(const char *path, char *const argv[]);
int execve(const char *path, char *const argv[], char *const envp[]);
int execvp(const char *file, char *const argv[]);
int execvpe(const char *file, char *const argv[], char *const envp[]); 

They are included from unistd.h header file.

Try using float: left (or right) instead of display: inline. Inline display replaces list-item display, which is what adds the bullet points.

I got the answer to my own question, ant this is:

select reverse(stuff(reverse('a,b,c,d,'), 1, N, ''))

Where N is the number of characters to remove. This avoids to write the complex column/string twice

The equivalent command in svn is:

svn log --diff -r revision

With sed it is possible to do something like this with a string:

echo "$STRING" | sed -e "s|.*AAA\(.*\)ZZZ.*|\1|"

And this will give me 1234 as a result.

You could do the same with re.sub function using the same regex.

>>> re.sub(r'.*AAA(.*)ZZZ.*', r'\1', 'gfgfdAAA1234ZZZuijjk')
'1234'

In basic sed, capturing group are represented by \(..\), but in python it was represented by (..).

There is a HUGE difference between VARCHAR and TEXT. While VARCHAR fields can be indexed, TEXT fields cannot. VARCHAR type fields are stored inline while TEXT are stored offline, only pointers to TEXT data is actually stored in the records.

If you have to index your field for faster search, update or delete than go for VARCHAR, no matter how big. A VARCHAR(10000000) will never be the same as a TEXT field bacause these two data types are different in nature.

• If you use you field only for archiving
• you don't care about data speed retrival
• you care about speed but you will use the operator '%LIKE%' in your search query so indexing will not help much
• you can't predict a limit of the data length

than go for TEXT.

Just use indexer

var valueAtIndex1 = myValues[1];

Here is an up-to-date approach as of October 2020, with Android X. This comes from Android's documentation, "Enable multidex for apps with over 64K methods."

For minSdk >= 21

You do not need to do anything. All of these devices use the Android RunTime (ART) VM, which supports multidex natively.

For minSdk < 21

In your module-level build.gradle, ensure that the following configurations are populated:

android {
    defaultConfig {
        multiDexEnabled true
    }
}

dependencies {
    implementation 'androidx.multidex:multidex:2.0.1'
}

You need to install explicit multidex support. The documentation includes three methods to do so, and you have to pick one.

For example, in your src/main/AndroidManifest.xml, you can declare MultiDexApplication as the application:name:

<manifest package="com.your.package"
          xmlns:android="http://schemas.android.com/apk/res/android">
    <application android:name="androidx.multidex.MultiDexApplication" />
</manifest>

If you want to treat accented latin characters (eg. à Ñ) as normal letters (ie. avoid matching them too), you'll also need to include the appropriate Unicode range (\u00C0-\u00FF) in your regex, so it would look like this:

/[^a-zA-Z\d\s:\u00C0-\u00FF]/g

• ^ negates what follows
• a-zA-Z matches upper and lower case letters
• \d matches digits
• \s matches white space (if you only want to match spaces, replace this with a space)
• : matches a colon
• \u00C0-\u00FF matches the Unicode range for accented latin characters.

nb. Unicode range matching might not work for all regex engines, but the above certainly works in Javascript (as seen in this pen on Codepen).

nb2. If you're not bothered about matching underscores, you could replace a-zA-Z\d with \w, which matches letters, digits, and underscores.

First of all, you have to create some dynamic memory space. Then you can just strcat the two strings into it. Or you can use the c++ "string" class. The old-school C way:

  char* catString = malloc(strlen(one)+strlen(two)+1);
  strcpy(catString, one);
  strcat(catString, two);
  // use the string then delete it when you're done.
  free(catString);

New C++ way

  std::string three(one);
  three += two;

Use the moment.js library for time and date management.

import moment = require('moment');

const now = moment();

now.subtract(7, 'seconds'); // 7 seconds ago
now.subtract(7, 'days');    // 7 days and 7 seconds ago
now.subtract(7, 'months');  // 7 months, 7 days and 7 seconds ago
now.subtract(7, 'years');   // 7 years, 7 months, 7 days and 7 seconds ago
// because `now` has been mutated, it no longer represents the current time

In Windows, capitalization in paths doesn't matter. In Linux it does.

When you autoload, use "Foo" not "foo".

I believe that will do the trick.

I think it works when you take it out of autoloading because codeigniter is smart enough to figure out the capitalization in the path and classes are case independent in php.

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

This is from http://www.acm.uiuc.edu/webmonkeys/book/c_guide/2.13.html#rand:

Declaration:

void srand(unsigned int seed); 

This function seeds the random number generator used by the function rand. Seeding srand with the same seed will cause rand to return the same sequence of pseudo-random numbers. If srand is not called, rand acts as if srand(1) has been called.

Just 2 simple steps to solve your issue

First of all check AppendDataBoundItems property and make it assign false

Secondly clear all the items using property .clear()

{
ddl1.Items.Clear();
ddl1.datasource = sql1;
ddl1.DataBind();
}

SELECT distinct idCustomer FROM reservations
WHERE DATEPART ( hour, insertDate) < 2
  and idCustomer is not null

Make sure your list parameter does not contain null values.

Here's an explanation:

WHERE field1 NOT IN (1, 2, 3, null)

is the same as:

WHERE NOT (field1 = 1 OR field1 = 2 OR field1 = 3 OR field1 = null)

• That last comparision evaluates to null.
• That null is OR'd with the rest of the boolean expression, yielding null. (*)
• null is negated, yielding null.
• null is not true - the where clause only keeps true rows, so all rows are filtered.

(*) Edit: this explanation is pretty good, but I wish to address one thing to stave off future nit-picking. (TRUE OR NULL) would evaluate to TRUE. This is relevant if field1 = 3, for example. That TRUE value would be negated to FALSE and the row would be filtered.

Here's a solution that shuffles a list of unique numbers (no repeats, ever).

for (var a=[],i=0;i<40;++i) a[i]=i;

function shuffle(array) {
  var tmp, current, top = array.length;
  if(top) while(--top) {
    current = Math.floor(Math.random() * (top + 1));
    tmp = array[current];

  return array;

a = shuffle(a);

If you want to allow repeated values (which is not what the OP wanted) then look elsewhere. :)

You could use stream operations (Collections.stream()) with Comparator.reverseOrder().

For example, say you have this collection:

List<String> items = new ArrayList<>();
items.add("item01");
items.add("item02");
items.add("item03");
items.add("item04");
items.add("item04");

To print the items in their "natural" order you could use the sorted() method (or leave it out and get the same result):

items.stream()
     .sorted()
     .forEach(item -> System.out.println(item));

Or to print them in descending (reverse) order, you could use the sorted method that takes a Comparator and reverse the order:

items.stream()
     .sorted(Comparator.reverseOrder())
     .forEach(item -> System.out.println(item));

Note this requires the collection to have implemented Comparable (as do Integer, String, etc.).

The first and most important step before starting a Vagrant is, check which all boxes are present in your system. Use this command for getting the list of boxes available.

vagrant box list

Then move to further process that is, selecting a particular box

vagrant init ubuntu/trusty64 (I have selected ubuntu/trusty64)

then,

vagrant up

This is the way I updated the master branch

This kind of error occurs commonly after deleting the initial code on your project

So, go ahead, first of all, verify the actual remote version, then remove the origin add the comment, and copy the repo URL into the project files.

$ git remote -v
$ git remote rm origin
$ git commit -m "your commit"
$ git remote add origin https://github.com/user/repo.git
$ git push -f origin master

Use the package "recommenderlab". Download and install the package. This package has a command "Normalize" in built. It also allows you to choose one of the many methods for normalization namely 'center' or 'Z-score' Follow the following example:

## create a matrix with ratings
m <- matrix(sample(c(NA,0:5),50, replace=TRUE, prob=c(.5,rep(.5/6,6))),nrow=5, ncol=10, dimnames = list(users=paste('u', 1:5, sep=&rdquo;), items=paste('i', 1:10, sep=&rdquo;)))

## do normalization
r <- as(m, "realRatingMatrix")
#here, 'centre' is the default method
r_n1 <- normalize(r) 
#here "Z-score" is the used method used
r_n2 <- normalize(r, method="Z-score")

r
r_n1
r_n2

## show normalized data
image(r, main="Raw Data")
image(r_n1, main="Centered")
image(r_n2, main="Z-Score Normalization")

From here.

For IIS7 and above, you also need to add the lines below:

 <system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
