Can you add static extensions to classes in C#? No but you can do this:

public static class Extensions
{
    public static T Create<T>(this T @this)
        where T : class, new()
    {
        return Utility<T>.Create();
    }
}

public static class Utility<T>
    where T : class, new()
{
    static Utility()
    {
        Create = Expression.Lambda<Func<T>>(Expression.New(typeof(T).GetConstructor(Type.EmptyTypes))).Compile();
    }
    public static Func<T> Create { get; private set; }
}

Here's how it works. While you can't technically write static extension methods, instead this code exploits a loophole in extension methods. That loophole being that you can call extension methods on null objects without getting the null exception (unless you access anything via @this).

So here's how you would use this:

    var ds1 = (null as DataSet).Create(); // as oppose to DataSet.Create()
    // or
    DataSet ds2 = null;
    ds2 = ds2.Create();

    // using some of the techniques above you could have this:
    (null as Console).WriteBlueLine(...); // as oppose to Console.WriteBlueLine(...)

Now WHY did I pick calling the default constructor as an example, and AND why don't I just return new T() in the first code snippet without doing all of that Expression garbage? Well todays your lucky day because you get a 2fer. As any advanced .NET developer knows, new T() is slow because it generates a call to System.Activator which uses reflection to get the default constructor before calling it. Damn you Microsoft! However my code calls the default constructor of the object directly.

Static extensions would be better than this but desperate times call for desperate measures.

In my case @Ilya Dyoshin's solution didn't work: The mediatype "*" was not allowed. I fix this error by adding a new converter to the restTemplate this way during initialization of the MockRestServiceServer:

  MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter = 
                      new MappingJackson2HttpMessageConverter();
  mappingJackson2HttpMessageConverter.setSupportedMediaTypes(
                                    Arrays.asList(
                                       MediaType.APPLICATION_JSON, 
                                       MediaType.APPLICATION_OCTET_STREAM));
  restTemplate.getMessageConverters().add(mappingJackson2HttpMessageConverter);
  mockServer = MockRestServiceServer.createServer(restTemplate);

The short answer is "no".

The current implementation of PHP is that of an interpreted language. You can argue the theoretical aspects of the fact that any language can technically be interpreted or compiled, but as it stands, the current implementations are such that PHP code requires an interpreter to run, and the interpreter manages the executing environment.

To answer your question about uploading pre-compiled PHP bytecode, it's probably possible, but you'd have to implement a way for the PHP interpreter to read in such a file and work with it. With existing opcode caches out there already, it doesn't seem like a task that would reap much reward.

Http response code of 201 for "Created" along with a "Location" header to point to where the client can find the newly created resource.

If you don't want 3D border use:

border:#f00 1px solid;

On my mac, the following inserts a single 'n' instead of newline:

sed 's/regexp/\n&/g'

This replaces with newline:

sed "s/regexp/\\`echo -e '\n\r'`/g"

There is a null coalescing operator (??), but it would not handle empty strings.

If you were only interested in dealing with null strings, you would use it like

string output = somePossiblyNullString ?? "0";

For your need specifically, there is the conditional operator bool expr ? true_value : false_value that you can use to simplify if/else statement blocks that set or return a value.

string output = string.IsNullOrEmpty(someString) ? "0" : someString;

You can define a "str_pad" function (as in php):

function str_pad(n) {
    return String("00" + n).slice(-2);
}

This should be a comment, but comments don't allow multi-line code.

Here's what's happening:

in Event.cpp

#include "Event.h"

preprocessor starts processing Event.h

#ifndef EVENT_H_

it isn't defined yet, so keep going

#define EVENT_H_
#include "common.h"

common.h gets processed ok

#include "Item.h"

Item.h gets processed ok

#include "Flight.h"

Flight.h gets processed ok

#include "Landing.h"

preprocessor starts processing Landing.h

#ifndef LANDING_H_

not defined yet, keep going

#define LANDING_H_

#include "Event.h"

preprocessor starts processing Event.h

#ifndef EVENT_H_

This IS defined already, the whole rest of the file gets skipped. Continuing with Landing.h

class Landing: public Event {

The preprocessor doesn't care about this, but the compiler goes "WTH is Event? I haven't heard about Event yet."

What I usually do is create a delete page that shows a confirmation form if the request method is "GET" and deletes the data if the method was "POST" and the user chose the "Yes" option.

Then, in the page with the delete link, I add an onclick function (or just use the jQuery confirm plugin) that uses AJAX to post to the link, bypassing the confirmation page.

Here's the idea in pseudo code:

delete.php:

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    if ($_POST['confirm'] == 'Yes') {
        delete_record($_REQUEST['id']); // From GET or POST variables
    }
    redirect($_POST['referer']);
}
?>

<form action="delete.php" method="post">
    Are you sure?
    <input type="submit" name="confirm" value="Yes">
    <input type="submit" name="confirm" value="No">

    <input type="hidden" name="id" value="<?php echo $_GET['id']; ?>">
    <input type="hidden" name="referer" value="<?php echo $_SERVER['HTTP_REFERER']; ?>">
</form>

Page with delete link:

<script>
    function confirmDelete(link) {
        if (confirm("Are you sure?")) {
            doAjax(link.href, "POST"); // doAjax needs to send the "confirm" field
        }
        return false;
    }
</script>

<a href="delete.php?id=1234" onclick="return confirmDelete(this);">Delete record</a>

If you can live with 01 for January instead of 1, then try...

d = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')
print datetime.date.strftime(d, "%m/%d/%y")

You can check the docs for other formatting directives.

I had the same problem. Open the cmd and type:

python -m pip install pylint

'temp_C' is a key inside dictionary that is inside a list that is inside a dictionary

This way works:

wjson['data']['current_condition'][0]['temp_C']
>> '10'

Here's my approach, inspired by @kepkin's solution:

# Adds ANSI colors to matched terms, similar to grep --color but without
# filtering unmatched lines. Example:
#   noisy_command | highlight ERROR INFO
#
# Each argument is passed into sed as a matching pattern and matches are
# colored. Multiple arguments will use separate colors.
#
# Inspired by https://stackoverflow.com/a/25357856
highlight() {
  # color cycles from 0-5, (shifted 31-36), i.e. r,g,y,b,m,c
  local color=0 patterns=()
  for term in "$@"; do
    patterns+=("$(printf 's|%s|\e[%sm\\0\e[0m|g' "${term//|/\\|}" "$(( color+31 ))")")
    color=$(( (color+1) % 6 ))
  done
  sed -f <(printf '%s\n' "${patterns[@]}")
}

This accepts multiple arguments (but doesn't let you customize the colors). Example:

$ noisy_command | highlight ERROR WARN

The right way to update the page currently displayed in the user's browser (without reloading it) is to have some code executing in the browser update the page's DOM.

That code is typically javascript that is embedded in or linked from the HTML page, hence the AJAX suggestion. (In fact, if we assume that the updated text comes from the server via an HTTP request, this is classic AJAX.)

It is also possible to implement this kind of thing using some browser plugin or add-on, though it may be tricky for a plugin to reach into the browser's data structures to update the DOM. (Native code plugins normally write to some graphics frame that is embedded in the page.)

A linebreak in regex is \n, so your script would be

var test = 'this\nis\na\ntest\nwith\newlines';
console.log(test.replace(/\n/g, ' '));

Lets say we have existing list, and gonna use java 8 for this activity `

import java.util.*;
import java.util.stream.Collectors;

public class AddingArray {

    public void addArrayInList(){
        List<Integer> list = Arrays.asList(3, 7, 9);

   // And we have an array of Integer type 

        int nums[] = {4, 6, 7};

   //Now lets add them all in list
   // converting array to a list through stream and adding that list to previous list
        list.addAll(Arrays.stream(nums).map(num -> 
                                       num).boxed().collect(Collectors.toList()));
     }
}

`

If your div rule is just div {...}, then #a {...} will be sufficient. If it is more complicated, you need a "more specific" selector, as defined by the CSS specification on specificity. (#a being more specific than div is just single aspect in the algorithm.)

In my case it was the problem of building the extension, I was pointing at an extension src (with manifest and everything) but without a build.

If you run into this scenario run npm i then npm build

Tested this code

java.text.DateFormat formatter = new java.text.SimpleDateFormat("MM-dd-yyyy");
java.util.Date newDate = new java.util.Date();
System.out.println(formatter.format(newDate ));

http://download.oracle.com/javase/1,5.0/docs/api/java/text/SimpleDateFormat.html

You have two boxes, left and right, for each label/input pair. Both boxes are in one row and have fixed width. Now, you just have to make label text float to the right with text-align: right;

Here's a simple example:

http://jsfiddle.net/qP46X/

I'm a little surprised nobody has suggested the most obvious solution:

grep -v '^#' filename

This solves the problem as stated.

But note that a common convention is for everything from a # to the end of a line to be treated as a comment:

sed 's/#.*$//' filename

though that treats, for example, a # character within a string literal as the beginning of a comment (which may or may not be relevant for your case) (and it leaves empty lines).

A line starting with arbitrary whitespace followed by # might also be treated as a comment:

grep -v '^ *#' filename

if whitespace is only spaces, or

grep -v '^[  ]#' filename

where the two spaces are actually a space followed by a literal tab character (type "control-v tab").

For all these commands, omit the filename argument to read from standard input (e.g., as part of a pipe).

Just set the view as null that will close the AlertDialog simple.

As of OS X 10.10.1 (Yosemite), the location of the cacerts file has been changed to

$(/usr/libexec/java_home)/jre/lib/security/cacerts

For me the easiest way is to do:

Random rnd = new Random();
r = min + rnd.nextInt(max - min);
//where min and max should be specified.

Thanks to @adam-singer explanation in here.

Without importing math // using basic envionment:

def ceil(fl): 
  return int(fl) + (1 if fl-int(fl) else 0)

def ceil(self, fl): 
  return int(fl) + (1 if fl-int(fl) else 0)

b) lambda:

ceil = lambda fl:int(fl)+(1 if fl-int(fl) else 0)

If you need to use Content-Type=x-www-urlencoded-form then DO NOT use FormDataCollection as parameter: In asp.net Core 2+ FormDataCollection has no default constructors which is required by Formatters. Use IFormCollection instead:

Here's a way to deep symbolize an object

After struggling with this for hours, I've come up with a solution that feels almost the best.

Chaos' answer of converting values to hexstring doesn't work with every datatype, specifically with datetime columns.

I use PHP's PDO::quote(), but as it comes with PHP, PDO::quote() is not supported for MS SQL Server and returns FALSE. The solution for it to work was to download some Microsoft bundles:

• Microsoft Drivers 3.0 for PHP for SQL Server (SQLSRV30.EXE): Download and follow the instructions to install.
• Microsoft® SQL Server® 2012 Native Client: Search through the extensive page for the Native Client. Even though it's 2012, I'm using it to connect to SQL Server 2008 (installing the 2008 Native Client didn't worked). Download and install.

After that you can connect in PHP with PDO using a DSN like the following example:

sqlsrv:Server=192.168.0.25; Database=My_Database;

Using the UID and PWD parameters in the DSN didn't worked, so username and password are passed as the second and third parameters on the PDO constructor when creating the connection. Now you can use PHP's PDO::quote(). Enjoy.

We can remove the element based on the property using the below 2 approaches.

1. Using filter method

testArray.filter(prop => prop.key !== 'Test Value')

2. Using splice method. For this method we need to find the index of the propery.

const index = testArray.findIndex(prop => prop.key === 'Test Value')
testArray.splice(index,1)

As far as I can tell, both syntaxes are equivalent. The first is SQL standard, the second is MySQL's extension.

So they should be exactly equivalent performance wise.

http://dev.mysql.com/doc/refman/5.6/en/insert.html says:

INSERT inserts new rows into an existing table. The INSERT ... VALUES and INSERT ... SET forms of the statement insert rows based on explicitly specified values. The INSERT ... SELECT form inserts rows selected from another table or tables.

Add the following 2 lines

var regex = new Regex(Regex.Escape(","));
sb_trim = regex.Replace(sb_trim, " ", 1);

If sb_trim= John,Smith,100000,M the above code will return "John Smith,100000,M"

isset is testing whether or not the key you are checking in the hash (or associative array) is "set". Set in this context just means if it knows the value. Nothing is a value. So it is defined as being an empty string.

For that reason, as long as you have an input field named userName, regardless of if they fill it in, this will be true. What you really want to do is check if the userName is equal to an empty string ''

If you do "git status" while having a merge conflict, the first thing git shows you is how to abort the merge.

1. Add a new install project to your solution.
2. Add targets from all projects you want to be installed.
3. Configure pre-requirements and choose "Check for .NET 3.5 and SQL Express" option. Choose the location from where missing components must be installed.
4. Configure your installer settings - company name, version, copyright, etc.
5. Build and go!

In my case I was facing the problem because in my tomcat process specific keystore was given using

-Djavax.net.ssl.trustStore=/pathtosomeselfsignedstore/truststore.jks

Wheras I was importing the certificate to the cacert of JRE/lib/security and the changes were not reflecting. Then I did below command where /tmp/cert1.test contains the certificate of the target server

keytool -import -trustcacerts -keystore /pathtosomeselfsignedstore/truststore.jks -storepass password123 -noprompt -alias rapidssl-myserver -file /tmp/cert1.test

We can double check if the certificate import is successful

keytool -list -v -keystore /pathtosomeselfsignedstore/truststore.jks

and see if your taget server is found against alias rapidssl-myserver

The answer from Constantin is spot on but for more background this behavior is inherited from Matlab.

The Matlab behavior is explained in the Figure Setup - Displaying Multiple Plots per Figure section of the Matlab documentation.

subplot(m,n,i) breaks the figure window into an m-by-n matrix of small subplots and selects the ithe subplot for the current plot. The plots are numbered along the top row of the figure window, then the second row, and so forth.

Here is an easy way to fetch data from a MySQL database using PDO.

define("DB_HOST", "localhost");    // Using Constants
define("DB_USER", "YourUsername");
define("DB_PASS", "YourPassword");
define("DB_NAME", "Yourdbname");

$dbc = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME.";charset-utf8mb4", DB_USER, DB_PASS);

$print = ""; // assign an empty string

$stmt = $dbc->query("SELECT * FROM tableName"); // fetch data
$stmt->setFetchMode(PDO::FETCH_OBJ);

$print .= '<table border="1px">';
$print .= '<tr><th>First name</th>';
$print .= '<th>Last name</th></tr>';

while ($names = $stmt->fetch()) { // loop and display data
    $print .= '<tr>';
    $print .= "<td>{$names->firstname}</td>";
    $print .= "<td>{$names->lastname}</td>";
    $print .= '</tr>';
}

$print .= "</table>";
echo $print;

To call a specific exception such as FileNotFoundException use this format

if (-not (Test-Path $file)) 
{
    throw [System.IO.FileNotFoundException] "$file not found."
}

To throw a general exception use the throw command followed by a string.

throw "Error trying to do a task"

When used inside a catch, you can provide additional information about what triggered the error

Escaping quotes in MSSQL is done by a double quote, so a '' or a "" will produce one escaped ' and ", respectively.

This will get all dll files and filter ones that match a regex of your directory structure.

Get-ChildItem C:\code -Recurse -filter "*.dll" | where { $_.directory -match 'C:\\code\\myproj.\\bin\\debug'}

If you just want the path, not the object you can add | select fullname to the end like this:

Get-ChildItem C:\code -Recurse -filter "*.dll" | where { $_.directory -match 'C:\\code\\myproj.\\bin\\debug'} | select fullname

Use the following:

type file.txt | findstr /v ERROR | findstr /v REFERENCE

This has the advantage of using standard tools in the Windows OS, rather than having to find and install sed/awk/perl and such.

See the following transcript for it in operation:

C:\>type file.txt
Good Line of data
bad line of C:\Directory\ERROR\myFile.dll
Another good line of data
bad line: REFERENCE
Good line

C:\>type file.txt | findstr /v ERROR | findstr /v REFERENCE
Good Line of data
Another good line of data
Good line

You can create a progress-bar of any html element that you can set a gradient to. (Pretty cool!) In the sample below, the background of an HTML element is updated with a linear gradient with JavaScript:

myElement.style.background = "linear-gradient(to right, #57c2c1 " + percentage + "%, #4a4a52 " + percentage + "%)";

PS I have set both locations percentage the same to create a hard line. Play with the design, you can even add a border to get that classic progress-bar look :)

    target_year = start_date.year + ((start_date.month + months) / 12)
    target_month = (start_date.month + months) % 12
    num_days_target_month = monthrange(target_year, target_month)[1]
    return start_date.replace(year=target_year, month=target_month, 
        day=min(start_date.day, num_days_target_month))

Alert alert = driver.switchTo().alert();

alert.accept();

You can also decline the alert box:

Alert alert = driver.switchTo().alert();

alert().dismiss();

I also found another way of doing this that gives proper 'x10(superscript)5' notation on the axes. I'm posting it here in the hope it might be useful to some. I got the code from here so I claim no credit for it, that rightly goes to Brian Diggs.

fancy_scientific <- function(l) {
     # turn in to character string in scientific notation
     l <- format(l, scientific = TRUE)
     # quote the part before the exponent to keep all the digits
     l <- gsub("^(.*)e", "'\\1'e", l)
     # turn the 'e+' into plotmath format
     l <- gsub("e", "%*%10^", l)
     # return this as an expression
     parse(text=l)
}

Which you can then use as

ggplot(data=df, aes(x=x, y=y)) +
   geom_point() +
   scale_y_continuous(labels=fancy_scientific) 

You can use this for header: Important: Put the following on your PHP pages that you want to include the content.

<?php
//at top:
require('header.php'); 
 ?>
 <?php
// at bottom:
require('footer.php');
?>

You can also include a navbar globaly just use this instead:

 <?php
 // At top:
require('header.php'); 
 ?>
  <?php
// At bottom:
require('footer.php');
 ?>
 <?php
 //Wherever navbar goes:
require('navbar.php'); 
?>

In header.php:

 <!DOCTYPE html>
 <html lang="en">
 <head>
    <meta charset="utf-8">
 <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
 </head>
 <body> 

Do Not close Body or Html tags!
Include html here:

 <?php
 //Or more global php here:

 ?>

Footer.php:

Code here:

<?php
//code

?>

Navbar.php:

<p> Include html code here</p>
<?php
 //Include Navbar PHP code here
 
?>

Benifits:

• Cleaner main php file (index.php) script.
• Change the header or footer. etc to change it on all pages with the include— Good for alerts on all pages etc...
• Time Saving!
• Faster page loads!
• you can have as many files to include as needed!
• server sided!

The only thing which worked for me is this

fetchData()
  .subscribe(
    (data) => {
       //Called when success
     },
    (error) => {
       //Called when error
    }
  ).add(() => {
       //Called when operation is complete (both success and error)
  });

With Java 8, you can easily achieve time in String format from long seconds like,

LocalTime.ofSecondOfDay(86399L)

Here, given value is max allowed to convert (upto 24 hours) and result will be

23:59:59

Pros : 1) No need to convert manually and to append 0 for single digit

Cons : work only for up to 24 hours

If you want to keep the heredoc indented for readability:

$ perl -pe 's/^\s*//' << EOF
     line 1
     line 2
EOF

The built-in method for supporting indented heredoc in Bash only supports leading tabs, not spaces.

Perl can be replaced with awk to save a few characters, but the Perl one is probably easier to remember if you know basic regular expressions.

Why not create a call like:

Service.GetCustomers();

that isn't async.

YourModel::where(function ($query) use($a,$b) {
    $query->where('a','=',$a)
          ->orWhere('b','=', $b);
})->where(function ($query) use ($c,$d) {
    $query->where('c','=',$c)
          ->orWhere('d','=',$d);
});

app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
    var data = {
        "fruit": {
            "apple": req.params.fruitName,
            "color": req.params.fruitColor
        }
    }; 

    send.json(data);
});

If that doesn't work, try using console.log(req.params) to see what it is giving you.

I'm not convinced this was the issue but through cPanel I'd noticed the PHP version was on 5.6 and changing it to 7.3 seemed to fix it. This was for a WordPress site. I noticed I could access images and generic PHP files but loading WordPress itself caused the error.

After making configurations, you can check by writing this command on terminal

sysctl -a | grep file

You can use System.Windows.Forms.Clipboard.SetText(...).

If an immutable map fits your needs then there is a library by google called guava (see also guava questions)

Guava provides an ImmutableMap with reliable user-specified iteration order. This ImmutableMap has O(1) performance for containsKey, get. Obviously put and remove are not supported.

ImmutableMap objects are constructed by using either the elegant static convenience methods of() and copyOf() or a Builder object.

Yes since there are 2 distinct Global Assembly Cache (GAC), you will have to manage each of them individually.

In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.

To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.

Source

Why?

It seems to be because there was a CLR change in .NET 4.0 but not in 2.0 to 3.5. The same thing happened with 1.1 to 2.0 CLR. It seems that the GAC has the ability to store different versions of assemblies as long as they are from the same CLR. They do not want to break old applications.

See the following information in MSDN about the GAC changes in 4.0.

For example, if both .NET 1.1 and .NET 2.0 shared the same GAC, then a .NET 1.1 application, loading an assembly from this shared GAC, could get .NET 2.0 assemblies, thereby breaking the .NET 1.1 application

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. As a result of this, there was no need in the previous two framework releases to split the GAC. The problem of breaking older (in this case, .NET 2.0) applications resurfaces in Net Framework 4.0 at which point CLR 4.0 released. Hence, to avoid interference issues between CLR 2.0 and CLR 4.0, the GAC is now split into private GACs for each runtime.

As the CLR is updated in future versions you can expect the same thing. If only the language changes then you can use the same GAC.

If you're using android studio an item is under your strings.xml

<string name="app_name">BareBoneProject</string>

It's better to change the name here because you might have used this string somewhere.Or maybe a library or something has used it.That's it.Just build and run and you'll get new name.Remember this won't change the package name or anything else.

Accepted answer in swift:

let group = DispatchGroup()

group.async(group: DispatchQueue.global(qos: .default), execute: {
    // block1
    print("Block1")
    Thread.sleep(forTimeInterval: 5.0)
    print("Block1 End")
})


group.async(group: DispatchQueue.global(qos: .default), execute: {
    // block2
    print("Block2")
    Thread.sleep(forTimeInterval: 8.0)
    print("Block2 End")
})

dispatch_group_notify(group, DispatchQueue.global(qos: .default), {
    // block3
    print("Block3")
})

// only for non-ARC projects, handled automatically in ARC-enabled projects.
dispatch_release(group)

Path.GetDirectoryName() returns the directory name, so for what you want (with the trailing reverse solidus character) you could call Path.GetDirectoryName(filePath) + Path.DirectorySeparatorChar.

You can, but the variable in your last include will overwrite the variable in your first one:

myfile.php

$var = 'test';

mysecondfile.php

$var = 'tester';

test.php

include 'myfile.php';
echo $var;

include 'mysecondfile.php';
echo $var;

Output:

test

tester

I suggest using different variable names.

I was getting this issue when trying to install on 2.3 devices (fine on 4.0.3). It ended up being due to a lib project i was using had multiple jars which were for stuff already in android e.g. HttpClient and XML parsers etc. Looking at logcat led me to find this as it was telling me it was skipping classes due to them already being present. Nice unhelpful original error there!

Given a floating point value, we can round it trivially with printf:

# round $1 to $2 decimal places
round() {
    printf "%.{$2:-0}f" "$1"
}

Then,

# do some math, bc style
math() {
    echo "$*" | bc -l
}

$ echo "Pi, to five decimal places, is $(round $(math "4*a(1)") 5)"
Pi, to five decimal places, is 3.14159

Or, to use the original request:

$ echo "3/2, rounded to the nearest integer, is $(round $(math "3/2") 0)"
3/2, rounded to the nearest integer, is 2

For money: decimal. It costs a little more memory, but doesn't have rounding troubles like double sometimes has.

Bitmap d = new Bitmap(c.Width, c.Height);

for (int i = 0; i < c.Width; i++)
{
    for (int x = 0; x < c.Height; x++)
    {
        Color oc = c.GetPixel(i, x);
        int grayScale = (int)((oc.R * 0.3) + (oc.G * 0.59) + (oc.B * 0.11));
        Color nc = Color.FromArgb(oc.A, grayScale, grayScale, grayScale);
        d.SetPixel(i, x, nc);
    }
}

This way it also keeps the alpha channel.
Enjoy.

You're calling writer.close(); after you've done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method.

public void writeToFile(){
    String file_text= pedStatusText + "     " + gatesStatus + "     " + DrawBridgeStatusText;
    try {
        writer.write(file_text);
        writer.flush();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

And add a method cleanUp to close the stream.

public void cleanUp() {
     writer.close();
}

This means that you have the responsibility to make sure that you're calling cleanUp when you're done writing to the file. Failure to do this will result in memory leaks and resource locking.

EDIT: You can create a new stream each time you want to write to the file, by moving writer into the writeToFile() method..

 public void writeToFile() {
    FileWriter writer = new FileWriter("status.txt", true);
    // ... Write to the file.

    writer.close();
 }

This is a good approach to show animation in and out using jQuery

  $(document).ready(function() {
      // show the alert
      $(".alert").first().hide().slideDown(500).delay(4000).slideUp(500, function () {
         $(this).remove(); 
      });
  });

Yes, use getJSONP. It's the only way to make cross domain/server async calls. (*Or it will be in the near future). Something like

$.getJSON('your-api-url/validate.php?'+$(this).serialize+'callback=?', function(data){
if(data)console.log(data);
});

The callback parameter will be filled in automatically by the browser, so don't worry.

On the server side ('validate.php') you would have something like this

<?php
if(isset($_GET))
{
//if condition is met
echo $_GET['callback'] . '(' . "{'message' : 'success', 'userID':'69', 'serial' : 'XYZ99UAUGDVD&orwhatever'}". ')';
}
else echo json_encode(array('error'=>'failed'));
?>

history.back() and switch to previous state often give effect not that you want. For example, if you have form with tabs and each tab has own state, this just switched previous tab selected, not return from form. In case nested states, you usually need so think about witch of parent states you want to rollback.

This directive solves problem

angular.module('app', ['ui-router-back'])

<span ui-back='defaultState'> Go back </span>

It returns to state, that was active before button has displayed. Optional defaultState is state name that used when no previous state in memory. Also it restores scroll position

Code

class UiBackData {
    fromStateName: string;
    fromParams: any;
    fromStateScroll: number;
}

interface IRootScope1 extends ng.IScope {
    uiBackData: UiBackData;
}

class UiBackDirective implements ng.IDirective {
    uiBackDataSave: UiBackData;

    constructor(private $state: angular.ui.IStateService,
        private $rootScope: IRootScope1,
        private $timeout: ng.ITimeoutService) {
    }

    link: ng.IDirectiveLinkFn = (scope, element, attrs) => {
        this.uiBackDataSave = angular.copy(this.$rootScope.uiBackData);

        function parseStateRef(ref, current) {
            var preparsed = ref.match(/^\s*({[^}]*})\s*$/), parsed;
            if (preparsed) ref = current + '(' + preparsed[1] + ')';
            parsed = ref.replace(/\n/g, " ").match(/^([^(]+?)\s*(\((.*)\))?$/);
            if (!parsed || parsed.length !== 4)
                throw new Error("Invalid state ref '" + ref + "'");
            let paramExpr = parsed[3] || null;
            let copy = angular.copy(scope.$eval(paramExpr));
            return { state: parsed[1], paramExpr: copy };
        }

        element.on('click', (e) => {
            e.preventDefault();

            if (this.uiBackDataSave.fromStateName)
                this.$state.go(this.uiBackDataSave.fromStateName, this.uiBackDataSave.fromParams)
                    .then(state => {
                        // Override ui-router autoscroll 
                        this.$timeout(() => {
                            $(window).scrollTop(this.uiBackDataSave.fromStateScroll);
                        }, 500, false);
                    });
            else {
                var r = parseStateRef((<any>attrs).uiBack, this.$state.current);
                this.$state.go(r.state, r.paramExpr);
            }
        });
    };

    public static factory(): ng.IDirectiveFactory {
        const directive = ($state, $rootScope, $timeout) =>
            new UiBackDirective($state, $rootScope, $timeout);
        directive.$inject = ['$state', '$rootScope', '$timeout'];
        return directive;
    }
}

angular.module('ui-router-back')
    .directive('uiBack', UiBackDirective.factory())
    .run(['$rootScope',
        ($rootScope: IRootScope1) => {

            $rootScope.$on('$stateChangeSuccess',
                (event, toState, toParams, fromState, fromParams) => {
                    if ($rootScope.uiBackData == null)
                        $rootScope.uiBackData = new UiBackData();
                    $rootScope.uiBackData.fromStateName = fromState.name;
                    $rootScope.uiBackData.fromStateScroll = $(window).scrollTop();
                    $rootScope.uiBackData.fromParams = fromParams;
                });
        }]);

When using SQLite:

REPLACE into table (id, name, age) values(1, "A", 19)

Provided that id is the primary key. Or else it just inserts another row. See INSERT (SQLite).

If it's a server socket, you should call listen() on your socket, and then getsockname() to find the port number on which it is listening:

struct sockaddr_in sin;
socklen_t len = sizeof(sin);
if (getsockname(sock, (struct sockaddr *)&sin, &len) == -1)
    perror("getsockname");
else
    printf("port number %d\n", ntohs(sin.sin_port));

As for the IP address, if you use INADDR_ANY then the server socket can accept connections to any of the machine's IP addresses and the server socket itself does not have a specific IP address. For example if your machine has two IP addresses then you might get two incoming connections on this server socket, each with a different local IP address. You can use getsockname() on the socket for a specific connection (which you get from accept()) in order to find out which local IP address is being used on that connection.

I think that maybe it is because you are declaring a variable that you already declared:

var Name = new Array(6);
//...
var Name[0] = Name_cell.getValue();  //  <-- Here's the issue: 'var'

I think this should be like this:

var Name = new Array(6);
//...
Name[0] = Name_cell.getValue();

Tell me if it works! ;)

If you want to create a new Thread...you can do something like this...

Thread t = new Thread(new Runnable() { public void run() { 
  // your code goes here... 
}});

When you subtract two variables of type TIMESTAMP, you get an INTERVAL DAY TO SECOND which includes a number of milliseconds and/or microseconds depending on the platform. If the database is running on Windows, systimestamp will generally have milliseconds. If the database is running on Unix, systimestamp will generally have microseconds.

  1  select systimestamp - to_timestamp( '2012-07-23', 'yyyy-mm-dd' )
  2*   from dual
SQL> /

SYSTIMESTAMP-TO_TIMESTAMP('2012-07-23','YYYY-MM-DD')
---------------------------------------------------------------------------
+000000000 14:51:04.339000000

You can use the EXTRACT function to extract the individual elements of an INTERVAL DAY TO SECOND

SQL> ed
Wrote file afiedt.buf

  1  select extract( day from diff ) days,
  2         extract( hour from diff ) hours,
  3         extract( minute from diff ) minutes,
  4         extract( second from diff ) seconds
  5    from (select systimestamp - to_timestamp( '2012-07-23', 'yyyy-mm-dd' ) diff
  6*           from dual)
SQL> /

      DAYS      HOURS    MINUTES    SECONDS
---------- ---------- ---------- ----------
         0         14         55     37.936

You can then convert each of those components into milliseconds and add them up

SQL> ed
Wrote file afiedt.buf

  1  select extract( day from diff )*24*60*60*1000 +
  2         extract( hour from diff )*60*60*1000 +
  3         extract( minute from diff )*60*1000 +
  4         round(extract( second from diff )*1000) total_milliseconds
  5    from (select systimestamp - to_timestamp( '2012-07-23', 'yyyy-mm-dd' ) diff
  6*           from dual)
SQL> /

TOTAL_MILLISECONDS
------------------
          53831842

Normally, however, it is more useful to have either the INTERVAL DAY TO SECOND representation or to have separate columns for hours, minutes, seconds, etc. rather than computing the total number of milliseconds between two TIMESTAMP values.

In general, you can't; you have to write the whole file again (at least from the point of change to the end).

In some specific cases you can do better than this -

if all your data elements are the same length and in no specific order, and you know the offset of the one you want to get rid of, you could copy the last item over the one to be deleted and truncate the file before the last item;

or you could just overwrite the data chunk with a 'this is bad data, skip it' value or keep a 'this item has been deleted' flag in your saved data elements such that you can mark it deleted without otherwise modifying the file.

This is probably overkill for short documents (anything under 100 KB?).

Edge (as opposed to IE11) has a better UI for Local storage / Session storage and cookies:

• Open Dev tools (F12)
• Go to Debugger tab
• Click the folder icon to show a list of resources - opens in a separate tab

Its very simple. Call one function inside another function with parameters.

    function fun1()
    {
     var a=10;
     var b=20;
     fun2(a,b); //calling function fun2() and passing 2 parameters
    }

   function fun2(num1,num2)
   {
    var sum;
    sum = num1+num2;
    return sum;
   }

   fun1(); //trigger function fun1

Kotlin

activity.supportFragmentManager.fragments.last()

You can use this in Swift 3 if you have an image to replace the clear button

func addTextfieldRightView(){

    let rightViewWidth:CGFloat = 30

    let viewMax = self.searchTxt.frame.height
    let buttonMax = self.searchTxt.frame.height - 16

    let buttonView = UIView(frame: CGRect(
        x: self.searchTxt.frame.width - rightViewWidth,
        y: 0,
        width: viewMax,
        height: viewMax))

    let myButton = UIButton(frame: CGRect(
        x: (viewMax - buttonMax) / 2,
        y: (viewMax - buttonMax) / 2,
        width: buttonMax,
        height: buttonMax))

    myButton.setImage(UIImage(named: "BlueClear")!, for: .normal)

    buttonView.addSubview(myButton)

    let clearPressed = UITapGestureRecognizer(target: self, action: #selector(SearchVC.clearPressed(sender:)))
    buttonView.isUserInteractionEnabled = true
    buttonView.addGestureRecognizer(clearPressed)

    myButton.addTarget(self, action: #selector(SearchVC.clearPressed(sender:)), for: .touchUpInside)

    self.searchTxt.rightView = buttonView
    self.searchTxt.rightViewMode = .whileEditing

You may need to run the cron job as a user with permissions to execute the PHP script. Try executing the cron job as root, using the command runuser (man runuser). Or create a system crontable and run the PHP script as an authorized user, as @Philip described.

I provide a detailed answer how to use cron in this stackoverflow post.

How to write a cron that will run a script every day at midnight?

I will assume that the test is going to be used in a function, similar to user97370's answer. I don't like that answer because it pollutes the global namespace. One way to fix it is to use a class instead:

class InitMyVariable(object):
  my_variable = None

def __call__(self):
  if self.my_variable is None:
   self.my_variable = ...

I don't like this, because it complicates the code and opens up questions such as, should this confirm to the Singleton programming pattern? Fortunately, Python has allowed functions to have attributes for a while, which gives us this simple solution:

def InitMyVariable():
  if InitMyVariable.my_variable is None:
    InitMyVariable.my_variable = ...
InitMyVariable.my_variable = None

I had the same error, just with a Nuget package i had installed (one that is not header only) and then tried to uninstall.
What was wrong for me was that i was still including a header for the package i just uninstalled in one of my .cpp files (pretty silly, yes).
I even removed the additional library directories link to it in Project -> Properties -> Linker -> General, but of course to no avail since i was still trying to reference the non-existent header.

Definitely a confusing error message in this case, since the header name was <boost/filesystem.hpp> but the error gave me "cannot open file 'llibboost_filesystem-vc140-mt-gd-1_59.lib'" and no line numbers or anything.

An alternative way is to install the Maven for Java plugin and create a maven project within Visual Studio. The steps are described in the official documentation:

1. From the Command Palette (Crtl+Shift+P), select Maven: Generate from Maven Archetype and follow the instructions, or
2. Right-click on a folder and select Generate from Maven Archetype.

Using Counter

from collections import Counter

def permutations(nums):
    ans = [[]]
    cache = Counter(nums)

    for idx, x in enumerate(nums):
        result = []
        for items in ans:
            cache1 = Counter(items)
            for id, n in enumerate(nums):
                if cache[n] != cache1[n] and items + [n] not in result:
                    result.append(items + [n])

        ans = result
    return ans

All OS comes with a default version of python and it resides in /usr/bin. All scripts that come with the OS (e.g. yum) point this version of python residing in /usr/bin. When you want to install a new version of python you do not want to break the existing scripts which may not work with new version of python.

The right way of doing this is to install the python as an alternate version.

e.g.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure --prefix=/usr/local/
make && make altinstall

Now by doing this the existing scripts like yum still work with /usr/bin/python. and your default python version would be the one installed in /usr/local/bin. i.e. when you type python you would get 2.7.3

This happens because. $PATH variable has /usr/local/bin before usr/bin.

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

If python2.7 still does not take effect as the default python version you would need to do

export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"

You can't currently animate on height when one of the heights involved is auto, you have to set two explicit heights.

The double space generally works well. However, sometimes the lacking newline in the PDF still occurs to me when using four pound sign sub titles #### in Jupyter Notebook, as the next paragraph is put into the subtitle as a single paragraph. No amount of double spaces and returns fixed this, until I created a notebook copy 'v. PDF' and started using a single backslash '\' which also indents the next paragraph nicely:

#### 1.1 My Subtitle  \

1.1 My Subtitle
    Next paragraph text.

An alternative to this, is to upgrade the level of your four # titles to three # titles, etc. up the title chain, which will remove the next paragraph indent and format the indent of the title itself (#### My Subtitle ---> ### My Subtitle).

### My Subtitle


1.1 My Subtitle

Next paragraph text.

This is what I've done to automatically add my local project node_modules/.bin path to PATH. In ~/.profile I added:

if [ -d "$PWD/node_modules/.bin" ]; then 
    PATH="$PWD/node_modules/.bin"
fi

Then reload your bash profile: source ~/.profile

This won't show custom events like those your script might create if it's a jquery plugin. for example :

jQuery(function($){
 var ThingName="Something";

 $("body a").live('click', function(Event){
   var $this = $(Event.target);
       $this.trigger(ThingName + ":custom-event-one");
 });

 $.on(ThingName + ":custom-event-one", function(Event){
   console.log(ThingName, "Fired Custom Event: 1", Event);
 })

});

The Event Panel under Scripts in chrome developer tools will not show you "Something:custom-event-one"

Let's Encrypt is a free, automated, and open certificate authority made by the Internet Security Research Group (ISRG). It is sponsored by well-known organisations such as Mozilla, Cisco or Google Chrome. All modern browsers are compatible and trust Let's Encrypt.

All certificates are free (even wildcard certificates)! For security reasons, the certificates expire pretty fast (after 90 days). For this reason, it is recommended to install an ACME client, which will handle automatic certificate renewal.

There are many clients you can use to install a Let's Encrypt certificate:

Let’s Encrypt uses the ACME protocol to verify that you control a given domain name and to issue you a certificate. To get a Let’s Encrypt certificate, you’ll need to choose a piece of ACME client software to use. - https://letsencrypt.org/docs/client-options/

Check out this code :-

/* Create Date Object */
Date date = new Date();
XMLGregorianCalendar xmlDate = null;
GregorianCalendar gc = new GregorianCalendar();

gc.setTime(date);

try{
    xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(gc);
}
catch(Exception e){
    e.printStackTrace();
}

System.out.println("XMLGregorianCalendar :- " + xmlDate);

The following worked for me

const conString = "postgres://YourUserName:YourPassword@YourHostname:5432/YourDatabaseName";

No, you can simply use com.fasterxml.jackson.databind.ObjectMapper. Most likely you forgot to fix your import-statements, delete all references to codehaus and you're golden.

Based on another question on stackoverflow, I got this code.. This calculates the result in meters, not in miles :)

 public static float distFrom(float lat1, float lng1, float lat2, float lng2) {
    double earthRadius = 6371000; //meters
    double dLat = Math.toRadians(lat2-lat1);
    double dLng = Math.toRadians(lng2-lng1);
    double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
               Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
               Math.sin(dLng/2) * Math.sin(dLng/2);
    double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
    float dist = (float) (earthRadius * c);

    return dist;
    }

In Perl 5.14 (it works in now in Perl 5.13), we'll be able to just use keys on the hash reference

use v5.13.7;

foreach my $key (keys $ad_grp_ref) {
    ...
}

Even better use implicit remoting to use a module from another Machine!

$s = New-PSSession Server-Name
Invoke-Command -Session $s -ScriptBlock {Import-Module ActiveDirectory}
Import-PSSession -Session $s -Module ActiveDirectory -Prefix REM

This will allow you to use the module off a remote PC for as long as the PSSession is connected.

I'll go into differences at the hardware level, on x86. This is mostly irrelevant unless you're writing a compiler or using assembly language. But it's nice to know.

Firstly, x86 has native support for the two's complement representation of signed numbers. You can use other representations but this would require more instructions and generally be a waste of processor time.

What do I mean by "native support"? Basically I mean that there are a set of instructions you use for unsigned numbers and another set that you use for signed numbers. Unsigned numbers can sit in the same registers as signed numbers, and indeed you can mix signed and unsigned instructions without worrying the processor. It's up to the compiler (or assembly programmer) to keep track of whether a number is signed or not, and use the appropriate instructions.

Firstly, two's complement numbers have the property that addition and subtraction is just the same as for unsigned numbers. It makes no difference whether the numbers are positive or negative. (So you just go ahead and ADD and SUB your numbers without a worry.)

The differences start to show when it comes to comparisons. x86 has a simple way of differentiating them: above/below indicates an unsigned comparison and greater/less than indicates a signed comparison. (E.g. JAE means "Jump if above or equal" and is unsigned.)

There are also two sets of multiplication and division instructions to deal with signed and unsigned integers.

Lastly: if you want to check for, say, overflow, you would do it differently for signed and for unsigned numbers.

This is not only applicable in Modernizer. I see some site implement like below to check whether it has javascript support or not.

<body class="no-js">
    <script>document.body.classList.remove('no-js');</script>
    ...
</body>

If javascript support is there, then it will remove no-js class. Otherwise no-js will remain in the body tag. Then they control the styles in the css when no javascript support.

.no-js .some-class-name {

}

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

The Pretty Formats section of the git show documentation contains

• format:<string>

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

The placeholders are:

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

I would suggest not to use @CachelookUp for Selenium WebDriver for StaleElementReferenceException.

If you are using @FindBy annotation and have @CacheLookUp, just comment it out and check.

I found another solution to get the data. according to the documentation Please check documentation link

In service file add following.

import { Injectable } from '@angular/core';
import { AngularFireDatabase } from 'angularfire2/database';

@Injectable()
export class MoviesService {

  constructor(private db: AngularFireDatabase) {}
  getMovies() {
    this.db.list('/movies').valueChanges();
  }
}

In Component add following.

import { Component, OnInit } from '@angular/core';
import { MoviesService } from './movies.service';

@Component({
  selector: 'app-movies',
  templateUrl: './movies.component.html',
  styleUrls: ['./movies.component.css']
})
export class MoviesComponent implements OnInit {
  movies$;

  constructor(private moviesDb: MoviesService) { 
   this.movies$ = moviesDb.getMovies();
 }

In your html file add following.

<li  *ngFor="let m of movies$ | async">{{ m.name }} </li>

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

Use the flex-grow property to make a flex item consume free space on the main axis.

This property will expand the item as much as possible, adjusting the length to dynamic environments, such as screen re-sizing or the addition / removal of other items.

A common example is flex-grow: 1 or, using the shorthand property, flex: 1.

Hence, instead of width: 96% on your div, use flex: 1.

You wrote:

So at the moment, it's set to 96% which looks OK until you really squash the screen - then the right hand div gets a bit starved of the space it needs.

The squashing of the fixed-width div is related to another flex property: flex-shrink

By default, flex items are set to flex-shrink: 1 which enables them to shrink in order to prevent overflow of the container.

To disable this feature use flex-shrink: 0.

For more details see The flex-shrink factor section in the answer here:

• What are the differences between flex-basis and width?

For my Apache2.4 + php5-fpm installation to start working, I needed to activate the following Apache modules:

sudo a2enmod proxy
sudo a2enmod proxy_fcgi

No need for proxy_http, and this is what sends all .php files straight to php5-fpm:

<FilesMatch \.php$>
    SetHandler "proxy:unix:/var/run/php5-fpm.sock|fcgi://localhost"
</FilesMatch>

A different take on this question, which might help someone:

I came here because I was debugging in Visual Studio on Windows, and I got confused about all this / vs \\ discussion (it really should not matter in most cases).

For me, the problem was: the "current directory" was not set to what I wanted in Visual Studio. It defaults to the directory of the executable (depending on how you set up your project).

Change it via: Right-click the solution -> Properties -> Working Directory

I only mention it because the question seems Windows-centric, which generally also means VisualStudio-centric, which tells me this hint might be relevant (:

I had the same error, i was able to resolve it by removing the 'Web Reference' and adding a 'Service Reference' instead

AFAIS, no one mentions of atomic reference.

Integer

public void swap(AtomicInteger a, AtomicInteger b){
    a.set(b.getAndSet(a.get()));
}

String

public void swap(AtomicReference<String> a, AtomicReference<String> b){
    a.set(b.getAndSet(a.get()));
}

Chengs's answer is correct, howewer according to the admin docs not every admin template can be overwritten this way: https://docs.djangoproject.com/en/1.9/ref/contrib/admin/#overriding-admin-templates

Templates which may be overridden per app or model

Not every template in contrib/admin/templates/admin may be overridden per app or per model. The following can:

app_index.html
change_form.html
change_list.html
delete_confirmation.html
object_history.html

For those templates that cannot be overridden in this way, you may still override them for your entire project. Just place the new version in your templates/admin directory. This is particularly useful to create custom 404 and 500 pages

I had to overwrite the login.html of the admin and therefore had to put the overwritten template in this folder structure:

your_project
 |-- your_project/
 |-- myapp/
 |-- templates/
      |-- admin/
          |-- login.html  <- do not misspell this

(without the myapp subfolder in the admin) I do not have enough repution for commenting on Cheng's post this is why I had to write this as new answer.

The direct answer to this question is:

if(rows.Any()) //prevent IndexOutOfRangeException for empty list
{
    rows.RemoveAt(rows.Count - 1);
}

However... in the specific case of this question, it makes more sense not to add the row in the first place:

Row row = new Row();
//...      

if (!row.cell[0].Equals("Something"))
{
    rows.Add(row);
}

TBH, I'd go a step further by testing "Something" against user."", and not even instantiating a Row unless the condition is satisfied, but seeing as user."" won't compile, I'll leave that as an exercise for the reader.

Your problem probably is that you haven't installed python. Meaning that, if you are using Windows, you have not downloaded the installer for Windows, that you can find on the official Python website.

In case you have, chances are that PyCharm cannot find your Python installation because its not in the default location, which is usually C:\Python27 or C:\Python33 (for me at least).

So, if you have installed Python and it still gives this error, then there can be two things that have happened:

1. You use a virtualenv and that virtualenv has been deleted or the filepath changed. In this case, you will have to find proceed to the next part of this answer.
2. Your python installation is not in its default place, in which case you will need to find its location, and locate the python.exe file.

Once you have located the necessary binaries, you will need to tell PyCharm were to look:

1. Open your settings dialogue CTRL + ALT + S

2. Then you will need to type in interpreter in the search box:

   

3. As you can see above, you will need to go to Project Interpreter and then go to Python Interpreter. The location has been selected for you in the above image.

4. To the side you will see a couple of options as icons, click the big + icon, then click on local, because your interpreter is on this computer.

5. This will open up a dialogue box. Make sure to select the python.exe file of that directory, do not give pycharm the whole directory. It just wants the interpreter.

Another developer use case: If the WindowManager or getWindow() is being called on onCreate() or onStart() or onResume(), a BadTokenException is thrown. You will need to wait until the view is prepared and attached.

Moving the code to onAttachedToWindow() solves it. It may not be a permanent solution, but as much as I could test, it always worked.

In my case, there was a need to increase the screen brightness when the activity became visible. The line getWindow().getAttributes().screenBrightness in the onResume() resulted in an exception. Moving the code to onAttachedToWindow() worked.

I don't know about javax.media.j3d, so I might be mistaken, but you usually want to investigate whether there is a memory leak. Well, as others note, if it was 64MB and you are doing something with 3d, maybe it's obviously too small...

But if I were you, I'll set up a profiler or visualvm, and let your application run for extended time (days, weeks...). Then look at the heap allocation history, and make sure it's not a memory leak.

If you use a profiler, like JProfiler or the one that comes with NetBeans IDE etc., you can see what object is being accumulating, and then track down what's going on.. Well, almost always something is incorrectly not removed from a collection...

If you just want to change where the iframe points to and not the actual content inside the iframe, you would just need to change the src attribute.

 $("#myiframe").attr("src", "newwebpage.html");

In my case, resetting ADB didn't make a difference. I also needed to delete my existing virtual devices, which were pretty old, and create new ones.

You may want to look at http://tug.ctan.org/tex-archive/macros/latex/contrib/float/ which allows you to define new floats using \newfloat

I say this because captions are usually applied to floats.

Straight ahead equations (those written with $ ... $, $$ ... $$, begin{equation}...) are in-line objects that do not support \caption.

This can be done using the following snippet just before \begin{document}

\usepackage{float}
\usepackage{aliascnt}
\newaliascnt{eqfloat}{equation}
\newfloat{eqfloat}{h}{eqflts}
\floatname{eqfloat}{Equation}

\newcommand*{\ORGeqfloat}{}
\let\ORGeqfloat\eqfloat
\def\eqfloat{%
  \let\ORIGINALcaption\caption
  \def\caption{%
    \addtocounter{equation}{-1}%
    \ORIGINALcaption
  }%
  \ORGeqfloat
}

and when adding an equation use something like

\begin{eqfloat}
\begin{equation}
f( x ) = ax + b
\label{eq:linear}
\end{equation}
\caption{Caption goes here}
\end{eqfloat}

Very simple, you create an array containing zeros using the reference shape:

result = np.zeros(b.shape)
# actually you can also use result = np.zeros_like(b) 
# but that also copies the dtype not only the shape

and then insert the array where you need it:

result[:a.shape[0],:a.shape[1]] = a

and voila you have padded it:

print(result)
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

You can also make it a bit more general if you define where your upper left element should be inserted

result = np.zeros_like(b)
x_offset = 1  # 0 would be what you wanted
y_offset = 1  # 0 in your case
result[x_offset:a.shape[0]+x_offset,y_offset:a.shape[1]+y_offset] = a
result

array([[ 0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.],
       [ 0.,  1.,  1.,  1.,  1.,  1.],
       [ 0.,  1.,  1.,  1.,  1.,  1.]])

but then be careful that you don't have offsets bigger than allowed. For x_offset = 2 for example this will fail.

If you have an arbitary number of dimensions you can define a list of slices to insert the original array. I've found it interesting to play around a bit and created a padding function that can pad (with offset) an arbitary shaped array as long as the array and reference have the same number of dimensions and the offsets are not too big.

def pad(array, reference, offsets):
    """
    array: Array to be padded
    reference: Reference array with the desired shape
    offsets: list of offsets (number of elements must be equal to the dimension of the array)
    """
    # Create an array of zeros with the reference shape
    result = np.zeros(reference.shape)
    # Create a list of slices from offset to offset + shape in each dimension
    insertHere = [slice(offset[dim], offset[dim] + array.shape[dim]) for dim in range(a.ndim)]
    # Insert the array in the result at the specified offsets
    result[insertHere] = a
    return result

And some test cases:

import numpy as np

# 1 Dimension
a = np.ones(2)
b = np.ones(5)
offset = [3]
pad(a, b, offset)

# 3 Dimensions

a = np.ones((3,3,3))
b = np.ones((5,4,3))
offset = [1,0,0]
pad(a, b, offset)

That attribute is basically the persistence for the "Associated Activity" selection above the layout. At runtime, a layout is always associated with an activity. It can of course be associated with more than one, but at least one. In the tool, we need to know about this mapping (which at runtime happens in the other direction; an activity can call setContentView(layout) to display a layout) in order to drive certain features.

Right now, we're using it for one thing only: Picking the right theme to show for a layout (since the manifest file can register themes to use for an activity, and once we know the activity associated with the layout, we can pick the right theme to show for the layout). In the future, we'll use this to drive additional features - such as rendering the action bar (which is associated with the activity), a place to add onClick handlers, etc.

The reason this is a tools: namespace attribute is that this is only a designtime mapping for use by the tool. The layout itself can be used by multiple activities/fragments etc. We just want to give you a way to pick a designtime binding such that we can for example show the right theme; you can change it at any time, just like you can change our listview and fragment bindings, etc.

(Here's the full changeset which has more details on this)

And yeah, the link Nikolay listed above shows how the new configuration chooser looks and works

One more thing: The "tools" namespace is special. The android packaging tool knows to ignore it, so none of those attributes will be packaged into the APK. We're using it for extra metadata in the layout. It's also where for example the attributes to suppress lint warnings are stored -- as tools:ignore.

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

I don't know if the solution below is more or less efficient than jspcal's answer, but I'm pretty sure it requires less object creation than Jamie's and George's.

string s = "THIS IS MY TEXT RIGHT NOW";
StringBuilder sb = new StringBuilder(s.Length);
bool capitalize = true;
foreach (char c in s) {
    sb.Append(capitalize ? Char.ToUpper(c) : Char.ToLower(c));
    capitalize = !Char.IsLetter(c);
}
return sb.ToString();

./bilet.sh: line 6: [: 7]: integer expression expected

Be careful with " "

./bilet.sh: line 9: [: missing `]'

This is because you need to have space between brackets like:

if [ "$age" -le 7 ] -o [ "$age" -ge 65 ]

look: added space, and no " "

This d = t.getElementsByTagName("tr") and this r = d.getElementsByTagName("td") are both arrays. The getElementsByTagName returns an collection of elements even if there's just one found on your match.

So you have to use like this:

var t = document.getElementById("table"), // This have to be the ID of your table, not the tag
    d = t.getElementsByTagName("tr")[0],
    r = d.getElementsByTagName("td")[0];

Place the index of the array as you want to access the objects.

Note that getElementById as the name says just get the element with matched id, so your table have to be like <table id='table'> and getElementsByTagName gets by the tag.

EDIT:

Well, continuing this post, I think you can do this:

var t = document.getElementById("table");
var trs = t.getElementsByTagName("tr");
var tds = null;

for (var i=0; i<trs.length; i++)
{
    tds = trs[i].getElementsByTagName("td");
    for (var n=0; n<tds.length;n++)
    {
        tds[n].onclick=function() { alert(this.innerHTML); }
    }
}

Try it!

<div> Vs <Section>

Round 1

<div>: The HTML element (or HTML Document Division Element) is the generic container for flow content, which does not inherently represent anything. It can be used to group elements for styling purposes (using the class or id attributes), or because they share attribute values, such as lang. It should be used only when no other semantic element (such as <article> or <nav>) is appropriate.

<section>: The HTML Section element (<section>) represents a generic section of a document, i.e., a thematic grouping of content, typically with a heading.

Round 2

<div>: Browser Support

<section>: Browser Support

The numbers in the table specifies the first browser version that fully supports the element.

In that vein, a div is relevant only from a pure CSS or DOM perspective, whereas a section is relevant also for semantics and, in a near future, for indexing by search engines.

In my case it was related to vs-code running on my Linux machine. I ignored a warning which popped up about file watcher bla bla. The solution is on the vs-code docs page for linux https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc

The solution is almost same (if not same) as the accepted answers, just has more explanation for anyone who gets here after running into the issues from vs-code.

Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point

Have a look at the helper class: Mage_Customer_Helper_Data

To simply get the customer name, you can write the following code:-

$customerName = Mage::helper('customer')->getCustomerName();

For more information about the customer's entity id, website id, email, etc. you can use getCustomer function. The following code shows what you can get from it:-

echo "<pre>"; print_r(Mage::helper('customer')->getCustomer()->getData()); echo "</pre>";

From the helper class, you can also get information about customer login url, register url, logout url, etc.

From the isLoggedIn function in the helper class, you can also check whether a customer is logged in or not.

Be careful - you have case mixing between local and remote branch!

Suppose you are in local branch downloadmanager now (git checkout downloadmanager)

You have next options:

1. Specify remote branch in pull/push commands every time (case sensitive):

   git pull origin DownloadManager

   or

   git pull origin downloadmanager:DownloadManager

2. Specify tracking branch on next push:

   git push -u origin DownloadManager

   (-u is a short form of --set-upstream)

   this will persist downloadmanager:DownloadManager link in config automatically (same result, as the next step).

3. Set in git config default remote tracking branch:

   git branch -u downloadmanager origin/DownloadManager

   (note, since git 1.8 for branch command -u is a short form of --set-upstream-to, which is a bit different from deprecated --set-upstream)

   or edit config manually (I prefer this way):

   git config --local -e

   -> This will open editor. Add block below (guess, after "master" block):

   [branch "downloadmanager"]
           remote = origin
           merge = refs/heads/DownloadManager
   

and after any of those steps you can use easily:

git pull

If you use TortoiseGit: RightClick on repo -> TortoiseGit -> Settings -> Git -> Edit local .git/config

For Laravel 2020. Ok, an example:

<form class="modal-content animate" action="{{ url('login_kun')  }}" method="post">
  @csrf   // !!! attention - this string is a must 
....
 </form>

And then in web.php:

Route::post("/login_kun", "LoginController@login");

And one more in new created LoginController:

 public function login(Request $request){
    dd($request->all());
}

and you are done my friend.

What is the right way to reverse a pandas DataFrame?

TL;DR: df[::-1]

This is objectively IMO the best method for reversing a DataFrame, because it is a ONE step operation, also very readable (assuming familiarity with slice notation).

Long Version

I've found the ol' slicing trick df[::-1] (or the equivalent df.loc[::-1]¹) to be the most concise and idiomatic way of reversing a DataFrame. This mirrors the python list reversal syntax lst[::-1] and is clear in its intent. With the loc syntax, you are also able to slice columns if required, so it is a bit more flexible.

Some points to consider while handling the index:

• "what if I want to reverse the index as well?"

  • you're already done. df[::-1] reverses both the index and values.

• "what if I want to drop the index from the result?"

  • you can call .reset_index(drop=True) at the end.

• "what if I want to keep the index untouched (IOW, only reverse the data, not the index)?"

  • this is somewhat unconventional because it implies the index isn't really relevant to the data. Perhaps consider removing it entirely? Although what you're asking for can technically be achieved using either df[:] = df[::-1] which creates an in-place update to df, or df.loc[::-1].set_index(df.index), which returns a copy.

_{1: df.loc[::-1] and df.iloc[::-1] are equivalent since the slicing syntax remains the same, whether you're reversing by position (iloc) or label (loc).}

The Proof is in the Pudding

X-axis represents the dataset size. Y-axis represents time taken to reverse. No method scales as well as the slicing trick, it's all the way at the bottom of the graph. Benchmarking code for reference, plots generated using perfplot.

Comments on other solutions

• df.reindex(index=df.index[::-1]) is clearly a popular solution, but on first glance, how obvious is it to an unfamiliar reader that this code is "reversing a DataFrame"? Additionally, this is reversing the index, then using that intermediate result to reindex, so this is essentially a TWO step operation (when it could've been just one).

• df.sort_index(ascending=False) may work in most cases where you have a simple range index, but this assumes your index was sorted in ascending order and so doesn't generalize well.

• PLEASE do not use iterrows. I see some options suggesting iterating in reverse. Whatever your use case, there is likely a vectorized method available, but if there isn't then you can use something a little more reasonable such as list comprehensions. See How to iterate over rows in a DataFrame in Pandas for more detail on why iterrows is an antipattern.

While it's true that json is a built-in module, I also found that on an Ubuntu system with python-minimal installed, you DO have python but you can't do import json. And then I understand that you would try to install the module using pip!

If you have python-minimal you'll get a version of python with less modules than when you'd typically compile python yourself, and one of the modules you'll be missing is the json module. The solution is to install an additional package, called libpython2.7-stdlib, to install all 'default' python libraries.

sudo apt install libpython2.7-stdlib

And then you can do import json in python and it would work!

If you are looking for optimizing your docker mysql container then the below command may help. I was able to run mysql docker container from a default 480mb to mere 100 mbs

wget is capable of doing what you are asking. Just try the following:

wget -p -k http://www.example.com/

The -p will get you all the required elements to view the site correctly (css, images, etc). The -k will change all links (to include those for CSS & images) to allow you to view the page offline as it appeared online.

From the Wget docs:

‘-k’
‘--convert-links’
After the download is complete, convert the links in the document to make them
suitable for local viewing. This affects not only the visible hyperlinks, but
any part of the document that links to external content, such as embedded images,
links to style sheets, hyperlinks to non-html content, etc.

Each link will be changed in one of the two ways:

    The links to files that have been downloaded by Wget will be changed to refer
    to the file they point to as a relative link.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
    downloaded, then the link in doc.html will be modified to point to
    ‘../bar/img.gif’. This kind of transformation works reliably for arbitrary
    combinations of directories.

    The links to files that have not been downloaded by Wget will be changed to
    include host name and absolute path of the location they point to.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
    ../bar/img.gif), then the link in doc.html will be modified to point to
    http://hostname/bar/img.gif. 

Because of this, local browsing works reliably: if a linked file was downloaded,
the link will refer to its local name; if it was not downloaded, the link will
refer to its full Internet address rather than presenting a broken link. The fact
that the former links are converted to relative links ensures that you can move
the downloaded hierarchy to another directory.

Note that only at the end of the download can Wget know which links have been
downloaded. Because of that, the work done by ‘-k’ will be performed at the end
of all the downloads. 

The comment by MK pointed me in the right direction.

In the case of Apache 2.4 and up, there are different defaults and a new directive.

I am running Apache 2.4.6, and I had to add the following directives to get it working:

SSLProxyEngine on
SSLProxyVerify none 
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off

Here's an example using XHR2:

function xhrToSend(){
    // Attempt to creat the XHR2 object
    var xhr;
    try{
        xhr = new XMLHttpRequest();
    }catch (e){
        try{
            xhr = new XDomainRequest();
        } catch (e){
            try{
                xhr = new ActiveXObject('Msxml2.XMLHTTP');
            }catch (e){
                try{
                    xhr = new ActiveXObject('Microsoft.XMLHTTP');
                }catch (e){
                    statusField('\nYour browser is not' + 
                        ' compatible with XHR2');                           
                }
            }
        }
    }
    xhr.open('POST', 'startStopResume.aspx', true);
    xhr.setRequestHeader("chunk", numberOfBLObsSent + 1);
    xhr.onreadystatechange = function (e) {
        if (xhr.readyState == 4 && xhr.status == 200) {
            receivedChunks++;
        }
    };
    xhr.send(chunk);
    numberOfBLObsSent++;
}; 

Hope that helps.

If you create your object, you can use the setRequestHeader function to assign a name, and a value before you send the request.

To get your program to run, please put jsp files under web-content and not under WEB-INF because in Eclipse the files are not accessed there by the server, so try starting the server and browsing to URL:

http://localhost:8080/YourProject/yourfile.jsp

then your problem will be solved.

Basically, flush() cleans out your RAM buffer, its real power is that it lets you continue to write to it afterwards - but it shouldn't be thought of as the best/safest write to file feature. It's flushing your RAM for more data to come, that is all. If you want to ensure data gets written to file safely then use close() instead.

Quick Answer:

foreach (var process in Process.GetProcessesByName("whatever"))
{
    process.Kill();
}

(leave off .exe from process name)

Could the Barcode Rendering Framework at Codeplex GitHub be of help?

Have you try changing your project name in package.json and execute command git init to reinitialize the existing Git, instead?

Your existing Git history will still exist.

import time
start = time.time()

fun()

# python 2
print 'It took', time.time()-start, 'seconds.'

# python 3
print('It took', time.time()-start, 'seconds.')

The following does not return a response:

You must return anything like return afunction() or return 'a string'.

This can solve the issue

The best one by far is

bool(re.search('ba[rzd]', 'foobarrrr'))

Returns True

I just tested this, it works sweet and doesn't require a lookup table. rand_alnum() sort of forces out alphanumerics but because it selects 62 out of a possible 256 chars it isn't a big deal.

#include <cstdlib>   // for rand()
#include <cctype>    // for isalnum()   
#include <algorithm> // for back_inserter
#include <string>

char 
rand_alnum()
{
    char c;
    while (!std::isalnum(c = static_cast<char>(std::rand())))
        ;
    return c;
}


std::string 
rand_alnum_str (std::string::size_type sz)
{
    std::string s;
    s.reserve  (sz);
    generate_n (std::back_inserter(s), sz, rand_alnum);
    return s;
}

You must remove alpha channels when uploading a photo to iTunes Connect.

You can do this by Preview, Photos App (old iPhoto), Pixelmator, Adobe Photoshop and GIMP.

Preview

1. Open the photo in Preview (if the photo is in your photo album in Photos app (the old iPhoto), then simply drag it from the album to desktop. Then control-click (right-click when mouse) the duplicated photo and select Preview.app under Open With menu).

2. Select Export… under File menu, and after selecting the destination, uncheck Alpha at the bottom, and click Export.

   

   

Pixelmator

1. Open the image in Pixelmator, without creating a new Pixelmator file. Just drag the photo to the Pixelmator window.

2. From Share menu, click Export for Web…

   

3. In the top bar, deselect Transparency.

4. Click Next and then save the new file somewhere.

Finally, upload the new photo to iTunes Connect.

GIMP

1. Open the photo in GIMP.

2. Open the Layer menu.

3. Under Transparency, click Remove Alpha Channel.

4. Save the photo.

Adobe Photoshop

1. Open the photo in Adobe Photoshop.

2. Under Layer menu, click Layer Mask and then From Transparency.

3. Delete the layer mask by right-clicking on the mask in the Layer panel and selecting Delete Layer Mask.

The python 2.5 documentation explains it well.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is ordered first (for example, [1,2] < [1,2,3]).

Unfortunately that page seems to have disappeared in the documentation for more recent versions.

You may take a look at this Java based framework for remote command execution, incl. via SSH: https://github.com/jkovacic/remote-exec It relies on two opensource SSH libraries, either JSch (for this implementation even an ECDSA authentication is supported) or Ganymed (one of these two libraries will be enough). At the first glance it might look a bit complex, you'll have to prepare plenty of SSH related classes (providing server and your user details, specifying encryption details, provide OpenSSH compatible private keys, etc., but the SSH itself is quite complex too). On the other hand, the modular design allows for simple inclusion of more SSH libraries, easy implementation of other command's output processing or even interactive classes etc.

Here is shortest way of doing it.

$userRecord = Model::where(['email'=>$email, 'password'=>$password])->first();

Button1.CssClass += " newClass";

This will not erase your original classes for that control. Try this, it should work.

The default IsSelected trigger changes 3 properties, Background, Foreground & BorderBrush. If you want to change the border as well as the background, just include this in your style trigger.

<Style TargetType="{x:Type dg:DataGridCell}">
    <Style.Triggers>
        <Trigger Property="dg:DataGridCell.IsSelected" Value="True">
            <Setter Property="Background" Value="#CCDAFF" />
            <Setter Property="BorderBrush" Value="Black" />
        </Trigger>
    </Style.Triggers>
</Style>

There is a little known feature in TypeScript that allows you to use Mixins to create re-usable small objects. You can compose these into larger objects using multiple inheritance (multiple inheritance is not allowed for classes, but it is allowed for mixins - which are like interfaces with an associated implenentation).

More information on TypeScript Mixins

I think you could use this technique to share common components between many classes in your game and to re-use many of these components from a single class in your game:

Here is a quick Mixins demo... first, the flavours that you want to mix:

class CanEat {
    public eat() {
        alert('Munch Munch.');
    }
}

class CanSleep {
    sleep() {
        alert('Zzzzzzz.');
    }
}

Then the magic method for Mixin creation (you only need this once somewhere in your program...)

function applyMixins(derivedCtor: any, baseCtors: any[]) {
    baseCtors.forEach(baseCtor => {
        Object.getOwnPropertyNames(baseCtor.prototype).forEach(name => {
             if (name !== 'constructor') {
                derivedCtor.prototype[name] = baseCtor.prototype[name];
            }
        });
    }); 
}

And then you can create classes with multiple inheritance from mixin flavours:

class Being implements CanEat, CanSleep {
        eat: () => void;
        sleep: () => void;
}
applyMixins (Being, [CanEat, CanSleep]);

Note that there is no actual implementation in this class - just enough to make it pass the requirements of the "interfaces". But when we use this class - it all works.

var being = new Being();

// Zzzzzzz...
being.sleep();

This is the most common feature of Notepad++ that I use to update my code.

All you need to do is:

• Select common string that is present in all lines.
• Press Ctrl + F
• In the Mark tab, paste the recurring string and check the Bookmark line checkbox.
• Click on Mark All
• Now go to menu Search → Bookmark → Remove Bookmarked Lines

You can refer to this link for pictorial explanation.

You need to convert the string to date using the to_date() function

SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31-Dec-2014','DD-MON-YYYY');

OR

SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014','DD MON YYYY');

OR

SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('2014-12-31','yyyy-MM-dd');

This will work only if OrderDate is stored in Date format. If it is Varchar you should apply to_date() func on that column also like

 SELECT * FROM OrderArchive
    WHERE to_date(OrderDate,'yyyy-Mm-dd') <= to_date('2014-12-31','yyyy-MM-dd');

you can use attribute data-html="true":

<a href="#" id="example"  rel="popover" 
    data-content="<div>This <b>is</b> your div content</div>" 
    data-html="true" data-original-title="A Title">popover</a>

There is 2 way for sort data

1) sorting just data and fill into grid:

DataGridView datagridview1 = new DataGridView(); // for show data
DataTable dt1 = new DataTable(); // have data
DataTable dt2 = new DataTable(); // temp data table
DataRow[] dra = dt1.Select("", "ID DESC");
if (dra.Length > 0)
    dt2 = dra.CopyToDataTable();
datagridview1.DataSource = dt2;

2) sort default view that is like of sort with grid column header:

DataGridView datagridview1 = new DataGridView(); // for show data
DataTable dt1 = new DataTable(); // have data
dt1.DefaultView.Sort = "ID DESC";
datagridview1.DataSource = dt1;

I do not have experience with version 7 of JBoss but with 5 I often had issues when redeploying apps which went away when I cleaned the work and tmp folder. I wrote a script for that which was executed everytime the server shut down. Maybe executing it before startup is better considering abnormal shutdowns (which weren't uncommon with Jboss 5 :))

You are using str methods on an open file object.

You can read the file as a list of lines by simply calling list() on the file object:

with open('goodlines.txt') as f:
    mylist = list(f)

This does include the newline characters. You can strip those in a list comprehension:

with open('goodlines.txt') as f:
    mylist = [line.rstrip('\n') for line in f]

If sometimes a link! will not work. so create a temporary object and take all values from the writable object then change the value and assign it to the writable object. it should perfectly.

var globalObject = {
    name:"a",
    age:20
}
function() {
    let localObject = {
    name:'a',
    age:21
    }
    this.globalObject = localObject;
}

You need spaces:

if [ "$s1" == "$s2" ]

I came across another performance comparison(latest update 10 April 2014). It compares the following:

• AutoFac
• LightCore (site is German)
• LinFu
• Ninject
• Petite
• Simple Injector (the fastest of all contestants)
• Spring.NET
• StructureMap
• Unity
• Windsor
• Hiro

Here is a quick summary from the post:

Conclusion

Ninject is definitely the slowest container.

MEF, LinFu and Spring.NET are faster than Ninject, but still pretty slow. AutoFac, Catel and Windsor come next, followed by StructureMap, Unity and LightCore. A disadvantage of Spring.NET is, that can only be configured with XML.

SimpleInjector, Hiro, Funq, Munq and Dynamo offer the best performance, they are extremely fast. Give them a try!

Especially Simple Injector seems to be a good choice. It's very fast, has a good documentation and also supports advanced scenarios like interception and generic decorators.

You can also try using the Common Service Selector Library and hopefully try multiple options and see what works best for you.

Some informtion about Common Service Selector Library from the site:

The library provides an abstraction over IoC containers and service locators. Using the library allows an application to indirectly access the capabilities without relying on hard references. The hope is that using this library, third-party applications and frameworks can begin to leverage IoC/Service Location without tying themselves down to a specific implementation.

Update

13.09.2011: Funq and Munq were added to the list of contestants. The charts were also updated, and Spring.NET was removed due to it's poor performance.

04.11.2011: "added Simple Injector, the performance is the best of all contestants".

You can add .a file in the linking command:

  gcc yourfiles /path/to/library/libLIBRARY.a

But this is not talking with gcc driver, but with ld linker as options like -Wl,anything are.

When you tell gcc or ld -Ldir -lLIBRARY, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose). To change order of library types checked you can use -Wl,-Bstatic and -Wl,-Bdynamic. Here is a man page of gnu LD: http://linux.die.net/man/1/ld

To link your program with lib1, lib3 dynamically and lib2 statically, use such gcc call:

gcc program.o -llib1 -Wl,-Bstatic -llib2 -Wl,-Bdynamic -llib3

Assuming that default setting of ld is to use dynamic libraries (it is on Linux).

Simple:

if ( $name eq 'tom' && $password eq '123!'
    || $name eq 'frank' && $password eq '321!'
) {

(use the high-precedence && and || in expressions, reserving and and or for flow control, to avoid common precedence errors)

Better:

my %password = (
    'tom' => '123!',
    'frank' => '321!',
);

if ( exists $password{$name} && $password eq $password{$name} ) {

Yes, use static

Always use static in .c files unless you need to reference the object from a different .c module.

Never use static in .h files, because you will create a different object every time it is included.

This sounds like an option

string.replace(string.find("%s"), string("%s").size(), "Something");

You could wrap this in a function but this one-line solution sounds acceptable. The problem is that this will change the first occurence only, you might want to loop over it, but it also allows you to insert several variables into this string with the same token (%s)

You can also simply use this:

.bg_rgba {
  background: linear-gradient(0deg, rgba(255, 255, 255, 0.9), rgba(255, 255, 255, 0.9)), url('https://picsum.photos/200');
  width: 200px;
  height: 200px;
  border: 1px solid black;
}

<div class='bg_rgba'></div>

You can change the opacity of the color to your preference.

For anyone checking this using python 3:

If you want to print the following output "100% correct":

python 3.8: print("100% correct")
python 3.7 and less: print("100%% correct")

A neat programming workaround for compatibility across diff versions of python is shown below:

Note: If you have to use this, you're probably experiencing many other errors... I'd encourage you to upgrade / downgrade python in relevant machines so that they are all compatible.

DevOps is a notable exception to the above -- implementing the following code would indeed be appropriate for specific DevOps / Debugging scenarios.

import sys

if version_info.major==3:
    if version_info.minor>=8:
        my_string = "100% correct"
    else:
        my_string = "100%% correct"

# Finally
print(my_string)

Copy code using clone and appendTo function :

Here is also working example jsfiddle

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
</head>
<body>
<div id="copy"><a href="http://brightwaay.com">Here</a> </div>
<br/>
<div id="copied"></div>
<script type="text/javascript">
    $(function(){
        $('#copy').clone().appendTo('#copied');
    });
</script>
</body>
</html>

Standard zip files normally use the deflate algorithm.

To extract files without using third party libraries use DeflateStream. You'll need a bit more information about the zip file archive format as Microsoft only provides the compression algorithm.

You may also try using zipfldr.dll. It is Microsoft's compression library (compressed folders from the Send to menu). It appears to be a com library but it's undocumented. You may be able to get it working for you through experimentation.

1. If Color is something that is specific to just Cars then that is the way you would limit its scope. If you are going to have another Color enum that other classes use then you might as well make it global (or at least outside Car).

2. It makes no difference. If there is a global one then the local one is still used anyway as it is closer to the current scope. Note that if you define those function outside of the class definition then you'll need to explicitly specify Car::Color in the function's interface.

If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your <thead> to <caption> and remove the <td> inside of it, and then set fixed widths for the cells in <tbody>.

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

You want both worlds.

You want multiple CSS files because your sanity is a terrible thing to waste.

At the same time, it's better to have a single, large file.

The solution is to have some mechanism that combines the multiple files in to a single file.

One example is something like

<link rel="stylesheet" type="text/css" href="allcss.php?files=positions.css,buttons.css,copy.css" />

Then, the allcss.php script handles concatenating the files and delivering them.

Ideally, the script would check the mod dates on all the files, creates a new composite if any of them changes, then returns that composite, and then checks against the If-Modified HTTP headers so as to not send redundant CSS.

This gives you the best of both worlds. Works great for JS as well.

my 2-cents:

import sys, traceback
try: 
  ...
except Exception, e:
  T, V, TB = sys.exc_info()
  print ''.join(traceback.format_exception(T,V,TB))

That would be the tempfile module.

It has functions to get the temporary directory, and also has some shortcuts to create temporary files and directories in it, either named or unnamed.

Example:

import tempfile

print tempfile.gettempdir() # prints the current temporary directory

f = tempfile.TemporaryFile()
f.write('something on temporaryfile')
f.seek(0) # return to beginning of file
print f.read() # reads data back from the file
f.close() # temporary file is automatically deleted here

For completeness, here's how it searches for the temporary directory, according to the documentation:

1. The directory named by the TMPDIR environment variable.
2. The directory named by the TEMP environment variable.
3. The directory named by the TMP environment variable.
4. A platform-specific location:
   • On RiscOS, the directory named by the Wimp$ScrapDir environment variable.
   • On Windows, the directories C:\TEMP, C:\TMP, \TEMP, and \TMP, in that order.
   • On all other platforms, the directories /tmp, /var/tmp, and /usr/tmp, in that order.
5. As a last resort, the current working directory.

Here is the Answer

The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website.

You want HttpRuntime.AppDomainAppPath.

If you're in an HTTP request, you can also call Server.MapPath("~/Whatever").

In short

Summary

In its simplest form, this technique aims to wrap code inside a function scope.

It helps decreases chances of:

• clashing with other applications/libraries
• polluting superior (global most likely) scope

It does not detect when the document is ready - it is not some kind of document.onload nor window.onload

It is commonly known as an Immediately Invoked Function Expression (IIFE) or Self Executing Anonymous Function.

Code Explained

var someFunction = function(){ console.log('wagwan!'); };

(function() {                   /* function scope starts here */
  console.log('start of IIFE');

  var myNumber = 4;             /* number variable declaration */
  var myFunction = function(){  /* function variable declaration */
    console.log('formidable!'); 
  };
  var myObject = {              /* object variable declaration */
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
})();                           /* function scope ends */

someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

In the example above, any variable defined in the function (i.e. declared using var) will be "private" and accessible within the function scope ONLY (as Vivin Paliath puts it). In other words, these variables are not visible/reachable outside the function. See live demo.

Javascript has function scoping. "Parameters and variables defined in a function are not visible outside of the function, and that a variable defined anywhere within a function is visible everywhere within the function." (from "Javascript: The Good Parts").

More details

Alternative Code

In the end, the code posted before could also be done as follows:

var someFunction = function(){ console.log('wagwan!'); };

var myMainFunction = function() {
  console.log('start of IIFE');

  var myNumber = 4;
  var myFunction = function(){ console.log('formidable!'); };
  var myObject = { 
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
};

myMainFunction();          // I CALL "myMainFunction" FUNCTION HERE
someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

See live demo.

The Roots

Iteration 1

One day, someone probably thought "there must be a way to avoid naming 'myMainFunction', since all we want is to execute it immediately."

If you go back to the basics, you find out that:

• expression: something evaluating to a value. i.e. 3+11/x
• statement: line(s) of code doing something BUT it does not evaluate to a value. i.e. if(){}

Similarly, function expressions evaluate to a value. And one consequence (I assume?) is that they can be immediately invoked:

 var italianSayinSomething = function(){ console.log('mamamia!'); }();

So our more complex example becomes:

var someFunction = function(){ console.log('wagwan!'); };

var myMainFunction = function() {
  console.log('start of IIFE');

  var myNumber = 4;
  var myFunction = function(){ console.log('formidable!'); };
  var myObject = { 
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
}();

someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

See live demo.

Iteration 2

The next step is the thought "why have var myMainFunction = if we don't even use it!?".

The answer is simple: try removing this, such as below:

 function(){ console.log('mamamia!'); }();

See live demo.

It won't work because "function declarations are not invokable".

The trick is that by removing var myMainFunction = we transformed the function expression into a function declaration. See the links in "Resources" for more details on this.

The next question is "why can't I keep it as a function expression with something other than var myMainFunction =?

The answer is "you can", and there are actually many ways you could do this: adding a +, a !, a -, or maybe wrapping in a pair of parenthesis (as it's now done by convention), and more I believe. As example:

 (function(){ console.log('mamamia!'); })(); // live demo: jsbin.com/zokuwodoco/1/edit?js,console.

or

 +function(){ console.log('mamamia!'); }(); // live demo: jsbin.com/wuwipiyazi/1/edit?js,console

or

 -function(){ console.log('mamamia!'); }(); // live demo: jsbin.com/wejupaheva/1/edit?js,console

• What does the exclamation mark do before the function?
• JavaScript plus sign in front of function name

So once the relevant modification is added to what was once our "Alternative Code", we return to the exact same code as the one used in the "Code Explained" example

var someFunction = function(){ console.log('wagwan!'); };

(function() {
  console.log('start of IIFE');

  var myNumber = 4;
  var myFunction = function(){ console.log('formidable!'); };
  var myObject = { 
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  console.log('end of IIFE');
})();

someFunction();            // reachable, hence works: see in the console
myFunction();              // unreachable, will throw an error, see in the console
myObject.anotherFunc();    // unreachable, will throw an error, see in the console

Demystifying Scopes

One thing one might wonder is "what happens when you do NOT define the variable 'properly' inside the function -- i.e. do a simple assignment instead?"

(function() {
  var myNumber = 4;             /* number variable declaration */
  var myFunction = function(){  /* function variable declaration */
    console.log('formidable!'); 
  };
  var myObject = {              /* object variable declaration */
    anotherNumber : 1001, 
    anotherFunc : function(){ console.log('formidable!'); }
  };
  myOtherFunction = function(){  /* oops, an assignment instead of a declaration */
    console.log('haha. got ya!');
  };
})();
myOtherFunction();         // reachable, hence works: see in the console
window.myOtherFunction();  // works in the browser, myOtherFunction is then in the global scope
myFunction();              // unreachable, will throw an error, see in the console

See live demo.

Basically, if a variable that was not declared in its current scope is assigned a value, then "a look up the scope chain occurs until it finds the variable or hits the global scope (at which point it will create it)".

When in a browser environment (vs a server environment like nodejs) the global scope is defined by the window object. Hence we can do window.myOtherFunction().

My "Good practices" tip on this topic is to always use var when defining anything: whether it's a number, object or function, & even when in the global scope. This makes the code much simpler.

Note:

• javascript does not have block scope (Update: block scope local variables added in ES6.)
• javascript has only function scope & global scope (window scope in a browser environment)

Next Steps

Once you get this IIFE concept, it leads to the module pattern, which is commonly done by leveraging this IIFE pattern. Have fun :)

I would read into a ByteArrayOutputStream and then call toByteArray() to get the resultant byte array. You don't need to define the size in advance (although it's possibly an optimisation if you know it. In many cases you won't)

You need dynamic memory management, and use the fgets function to read your line. However, there seems to be no way to see how many characters it read. So you use fgetc:

char * getline(void) {
    char * line = malloc(100), * linep = line;
    size_t lenmax = 100, len = lenmax;
    int c;

    if(line == NULL)
        return NULL;

    for(;;) {
        c = fgetc(stdin);
        if(c == EOF)
            break;

        if(--len == 0) {
            len = lenmax;
            char * linen = realloc(linep, lenmax *= 2);

            if(linen == NULL) {
                free(linep);
                return NULL;
            }
            line = linen + (line - linep);
            linep = linen;
        }

        if((*line++ = c) == '\n')
            break;
    }
    *line = '\0';
    return linep;
}

Note: Never use gets ! It does not do bounds checking and can overflow your buffer

In case of Linear Regression the outcome is continuous while in case of Logistic Regression outcome is discrete (not continuous)

To perform Linear regression we require a linear relationship between the dependent and independent variables. But to perform Logistic regression we do not require a linear relationship between the dependent and independent variables.

Linear Regression is all about fitting a straight line in the data while Logistic Regression is about fitting a curve to the data.

Linear Regression is a regression algorithm for Machine Learning while Logistic Regression is a classification Algorithm for machine learning.

Linear regression assumes gaussian (or normal) distribution of dependent variable. Logistic regression assumes binomial distribution of dependent variable.

In case anyone has this problem, I had a similar problem to qix, but more nuanced.

New shell terminals would default to a different version of node. I would change my terminal to the node I wanted, but when the bundle script run, it ran in a new shell, and it got the default version which did not have react-native installed.

I used nvm alias default x.x.x so that new shells would inherit the default version I wanted.

Easiest way is to turn the list to tuple first

t = tuple(l)
query = "select name from studens where id IN {}".format(t)

Try specifying a DC in DomainB using the -Server property. Ex:

Expanded answer, was my first answer so excuse if there wasn’t enough detail before.

For Bootstrap 3.x I personally prefer CSS animations and I've been using animate.css & along with the Bootstrap Dropdown Javascript Hooks. Although it might not have the exactly effect you're after it's a pretty flexible approach.

Step 1: Add animate.css to your page with the head tags:

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.4.0/animate.min.css">

Step 2: Use the standard Bootstrap HTML on the trigger:

<div class="dropdown">
  <button type="button" data-toggle="dropdown">Dropdown trigger</button>

  <ul class="dropdown-menu">
    ...
  </ul>
</div>

Step 3: Then add 2 custom data attributes to the dropdrop-menu element; data-dropdown-in for the in animation and data-dropdown-out for the out animation. These can be any animate.css effects like fadeIn or fadeOut

<ul class="dropdown-menu" data-dropdown-in="fadeIn" data-dropdown-out="fadeOut">
......
</ul>

Step 4: Next add the following Javascript to read the data-dropdown-in/out data attributes and react to the Bootstrap Javascript API hooks/events (http://getbootstrap.com/javascript/#dropdowns-events):

var dropdownSelectors = $('.dropdown, .dropup');

// Custom function to read dropdown data
// =========================
function dropdownEffectData(target) {
  // @todo - page level global?
  var effectInDefault = null,
      effectOutDefault = null;
  var dropdown = $(target),
      dropdownMenu = $('.dropdown-menu', target);
  var parentUl = dropdown.parents('ul.nav'); 

  // If parent is ul.nav allow global effect settings
  if (parentUl.size() > 0) {
    effectInDefault = parentUl.data('dropdown-in') || null;
    effectOutDefault = parentUl.data('dropdown-out') || null;
  }

  return {
    target:       target,
    dropdown:     dropdown,
    dropdownMenu: dropdownMenu,
    effectIn:     dropdownMenu.data('dropdown-in') || effectInDefault,
    effectOut:    dropdownMenu.data('dropdown-out') || effectOutDefault,  
  };
}

// Custom function to start effect (in or out)
// =========================
function dropdownEffectStart(data, effectToStart) {
  if (effectToStart) {
    data.dropdown.addClass('dropdown-animating');
    data.dropdownMenu.addClass('animated');
    data.dropdownMenu.addClass(effectToStart);    
  }
}

// Custom function to read when animation is over
// =========================
function dropdownEffectEnd(data, callbackFunc) {
  var animationEnd = 'webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend';
  data.dropdown.one(animationEnd, function() {
    data.dropdown.removeClass('dropdown-animating');
    data.dropdownMenu.removeClass('animated');
    data.dropdownMenu.removeClass(data.effectIn);
    data.dropdownMenu.removeClass(data.effectOut);

    // Custom callback option, used to remove open class in out effect
    if(typeof callbackFunc == 'function'){
      callbackFunc();
    }
  });
}

// Bootstrap API hooks
// =========================
dropdownSelectors.on({
  "show.bs.dropdown": function () {
    // On show, start in effect
    var dropdown = dropdownEffectData(this);
    dropdownEffectStart(dropdown, dropdown.effectIn);
  },
  "shown.bs.dropdown": function () {
    // On shown, remove in effect once complete
    var dropdown = dropdownEffectData(this);
    if (dropdown.effectIn && dropdown.effectOut) {
      dropdownEffectEnd(dropdown, function() {}); 
    }
  },  
  "hide.bs.dropdown":  function(e) {
    // On hide, start out effect
    var dropdown = dropdownEffectData(this);
    if (dropdown.effectOut) {
      e.preventDefault();   
      dropdownEffectStart(dropdown, dropdown.effectOut);   
      dropdownEffectEnd(dropdown, function() {
        dropdown.dropdown.removeClass('open');
      }); 
    }    
  }, 
});

Step 5 (optional): If you want to speed up or alter the animation you can do so with CSS like the following:

.dropdown-menu.animated {
  /* Speed up animations */
  -webkit-animation-duration: 0.55s;
  animation-duration: 0.55s;
  -webkit-animation-timing-function: ease;
  animation-timing-function: ease;
}

It appears that Linq2Sql has this "problem" as well. It appears that there is a valid reason for this behavior due to whether ANSI NULLs are ON or OFF but it boggles the mind why a straight "== null" will in fact work as you'd expect.
