I had the same issue with a site which previously was running fine. I resolved the issue by deleting the temporary files from C:\WINDOWS\Microsoft.NET\Framework\v#.#.#####\Temporary ASP.NET Files\@projectName\###CC##C\###C#CC

For me

grep -b "searchsomething" *.log

worked as I wanted

if you just want to check if one or the other element are present you can use this custom helper

Handlebars.registerHelper('if_or', function(elem1, elem2, options) {
  if (Handlebars.Utils.isEmpty(elem1) && Handlebars.Utils.isEmpty(elem2)) {
    return options.inverse(this);
  } else {
    return options.fn(this);
  }
});

like this

{{#if_or elem1 elem2}}
  {{elem1}} or {{elem2}} are present
{{else}}
  not present
{{/if_or}}

if you also need to be able to have an "or" to compare function return values I would rather add another property that returns the desired result.

The templates should be logicless after all!

This can be done very easily using a PostBackUrl and a regular button.

<asp:Button ID="Button1" runat="server" Text="Name of web location" PostBackUrl="web address" />

If you add the extension .SH to the environment variable PATHEXT, you will be able to run shell scripts from PowerShell by only using the script name with arguments:

PS> .\script.sh args

If you store your scripts in a directory that is included in your PATH environment variable, you can run it from anywhere, and omit the extension and path:

PS> script args

Note: sh.exe or another *nix shell must be associated with the .sh extension.

I need to add that, if the Module name and the sub name is the same you have such issue. Consider change the Module name to mod_Test instead of "Test" which is the same as the sub.

This is the Windows version of a fork bomb.

%0 is the name of the currently executing batch file. A batch file that contains just this line:

%0|%0

Is going to recursively execute itself forever, quickly creating many processes and slowing the system down.

This is not a bug in windows, it is just a very stupid thing to do in a batch file.

For the iterative algorithm, however, we have:

int iterativeEGCD(long long n, long long m) {
    long long a;
    int numberOfIterations = 0;
    while ( n != 0 ) {
         a = m;
         m = n;
         n = a % n;
        numberOfIterations ++;
    }
    printf("\nIterative GCD iterated %d times.", numberOfIterations);
    return m;
}

With Fibonacci pairs, there is no difference between iterativeEGCD() and iterativeEGCDForWorstCase() where the latter looks like the following:

int iterativeEGCDForWorstCase(long long n, long long m) {
    long long a;
    int numberOfIterations = 0;
    while ( n != 0 ) {
         a = m;
         m = n;
         n = a - n;
        numberOfIterations ++;
    }
    printf("\nIterative GCD iterated %d times.", numberOfIterations);
    return m;
}

Yes, with Fibonacci Pairs, n = a % n and n = a - n, it is exactly the same thing.

We also know that, in an earlier response for the same question, there is a prevailing decreasing factor: factor = m / (n % m).

Therefore, to shape the iterative version of the Euclidean GCD in a defined form, we may depict as a "simulator" like this:

void iterativeGCDSimulator(long long x, long long y) {
    long long i;
    double factor = x / (double)(x % y);
    int numberOfIterations = 0;
    for ( i = x * y ; i >= 1 ; i = i / factor) {
        numberOfIterations ++;
    }
    printf("\nIterative GCD Simulator iterated %d times.", numberOfIterations);
}

Based on the work (last slide) of Dr. Jauhar Ali, the loop above is logarithmic.

Yes, small Oh because the simulator tells the number of iterations at most. Non Fibonacci pairs would take a lesser number of iterations than Fibonacci, when probed on Euclidean GCD.

There is a super() in python also.

Example for how a super class method is called from a sub class method

class Dog(object):
    name = ''
    moves = []

    def __init__(self, name):
        self.name = name

    def moves_setup(self,x):
        self.moves.append('walk')
        self.moves.append('run')
        self.moves.append(x)
    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super().moves_setup("hello world")
        self.moves.append('fly')
dog = Superdog('Freddy')
print (dog.name)
dog.moves_setup()
print (dog.get_moves()) 

This example is similar to the one explained above.However there is one difference that super doesn't have any arguments passed to it.This above code is executable in python 3.4 version.

In the specific case of a String array you could initialize the array using the Split Function as it returns a String array rather than a Variant array:

Dim arrWsNames() As String
arrWsNames = Split("Value1,Value2,Value3", ",")

This allows you to avoid using the Variant data type and preserve the desired type for arrWsNames.

This bug still exists in 0.8+/1.10

With Jackson

compile 'com.fasterxml.jackson.dataformat:jackson-dataformat-csv:2.2.2'

I had to include as well as the above suggestion before it would compile

exclude 'META-INF/services/com.fasterxml.jackson.core.JsonFactory'

This is possible with switch enhancements in Java 14. Following is a fairly intuitive example of how the same can be achieved.

switch (month) {
    case 1, 3, 5, 7, 8, 10, 12 -> System.out.println("this month has 31 days");
    case 4, 6, 9 -> System.out.println("this month has 30 days");
    case 2 -> System.out.println("February can have 28 or 29 days");
    default -> System.out.println("invalid month");
}

var logged_in = false;
logged_in = !logged_in;

A little example:

var logged_in = false;_x000D_
_x000D_
_x000D_
$("#enable").click(function() {_x000D_
    logged_in = !logged_in;_x000D_
    checkLogin();_x000D_
});_x000D_
_x000D_
function checkLogin(){_x000D_
    if (logged_in)_x000D_
        $("#id_test").removeClass("test").addClass("test_hidde");_x000D_
    else_x000D_
        $("#id_test").removeClass("test_hidde").addClass("test");_x000D_
    $("#id_test").text($("#id_test").text()+', '+logged_in);_x000D_
}

.test_hidde{_x000D_
    color: #000;_x000D_

There is no such option. What you can do is to run mkdir -p before copying the file

I made a very cool script you can use to copy files in locations that doesn't exist

#!/bin/bash
if [ ! -d "$2" ]; then
    mkdir -p "$2"
fi
cp -R "$1" "$2"

Now just save it, give it permissions and run it using

./cp-improved SOURCE DEST

I put -R option but it's just a draft, I know it can be and you will improve it in many ways. Hope it helps you

As far as I can see, you just added heredoc by mistake
No need to use ugly heredoc syntax here.
Just remove it and everything will work:

<p>Hello</p>
<p><?= _("World"); ?></p>

You can use >> to print in another file.

echo "hello" >> logfile.txt

Let the command you are trying to pass be

os.system('x')

then you covert it to a statement

t = os.system('x')

now the python will be waiting for the output from the commandline so that it could be assigned to the variable t.

//javascript
//teams.Table does not exist

function OnSuccessJSON(data, status) {
    var teams = eval('(' + data.d + ')');
    var listItems = "";
    for (var i = 0; i < teams.length; i++) {
      listItems += "<option value='" + teams[i][0]+ "'>" + teams[i][1] + "</option>";
    }
    $("#<%=ddlTeams.ClientID%>").html(listItems);
} 

Completely removed from java 8 +
Partially removed from java 7 (interned Strings for example)

As Benjamin said in his answer, TC39 explicitly decided not to include this feature at least for ES2015. However, the consensus seems to be that they will add it in ES2016.

The syntax hasn't been decided yet, but there's a preliminary proposal for ES2016 that will allow you to declare static properties on a class.

Thanks to the magic of babel, you can use this today. Enable the class properties transform according to these instructions and you're good to go. Here's an example of the syntax:

class foo {
  static myProp = 'bar'
  someFunction() {
    console.log(this.myProp)
  }
}

This proposal is in a very early state, so be prepared to tweak your syntax as time goes on.

class TableViewCell: UITableViewCell {
   @IBOutlet weak var oneButton: UIButton!
   @IBOutlet weak var twoButton: UIButton!
}


class TableViewController: UITableViewController {

  override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! TableViewCell

    cell.oneButton.addTarget(self, action: #selector(TableViewController.oneTapped(_:)), for: .touchUpInside)
    cell.twoButton.addTarget(self, action: #selector(TableViewController.twoTapped(_:)), for: .touchUpInside)

    return cell
}

func oneTapped(_ sender: Any?) {

    print("Tapped")
}

func twoTapped(_ sender: Any?) {

    print("Tapped")
   }
}

Just add

.flex-control-thumbs li {
width: auto; 
}

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

PHP setcookie()

Taken from that page, this will unset all of the cookies for your domain:

// unset cookies
if (isset($_SERVER['HTTP_COOKIE'])) {
    $cookies = explode(';', $_SERVER['HTTP_COOKIE']);
    foreach($cookies as $cookie) {
        $parts = explode('=', $cookie);
        $name = trim($parts[0]);
        setcookie($name, '', time()-1000);
        setcookie($name, '', time()-1000, '/');
    }

This problem comes from a strange quirk within Office/Windows.

After developing the same piece of VBA code and running it hundreds of times (literally) over the last couple days I ran into this problem just now. The only thing that has been different is that just prior to experiencing this perplexing problem I accidentally ended the execution of the VBA code with an unorthodox method.

I cleaned out all temp files, rebooted, etc... When I ran the code again after all of this I still got the issue - before I entered the first loop. It makes sense that "press "Debug" button in the popup, then press twice [Ctrl+Break] and after this can continue without stops" because something in the combination of Office/Windows has not released the execution. It is stuck.

The redundant Ctrl+Break action probably resolves the lingering execution.

window.location.replace('http://sidanmor.com');

It's better than using window.location.href = 'http://sidanmor.com';

Using replace() is better because it does not keep the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco.

If you want to simulate someone clicking on a link, use window.location.href

If you want to simulate an HTTP redirect, use window.location.replace

For example:

// similar behavior as an HTTP redirect
window.location.replace("http://sidanmor.com");

// similar behavior as clicking on a link
window.location.href = "http://sidanmor.com";

I just found this extension called beautify in the Market Place and yes, it's another config\settings file. :)

Beautify javascript, JSON, CSS, Sass, and HTML in Visual Studio Code.

VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use. This extension enables running js-beautify in VS Code, AND honouring any .jsbeautifyrc file in the open file's path tree to load your code styling. Run with F1 Beautify (to beautify a selection) or F1 Beautify file.

For help on the settings in the .jsbeautifyrc see Settings.md

Here is the GitHub repository: https://github.com/HookyQR/VSCodeBeautify

I imagine that trygetvalue is doing something more like:

if(myDict.ReallyOptimisedVersionofContains(someKey))
{ 
  someVal = myDict[someKey];
  return true;
}
return false;

So hopefully no try/catch anywhere.

I think it is just a method of convenience really. I generally use it as it saves a line of code or two.

it depends on what role this foreign key plays in your relation.

1. if this foreign key is also a key attribute in your relation, then it can't be NULL
2. if this foreign key is a normal attribute in your relation, then it can be NULL.

Your question answers itself ;) If og_date contains the date, it's probably a string, so og_date.value is undefined.

Simply use og_date.split('-') instead of og_date.value.split('-')

I know it's a relative old post but, I would like to share what worked for me: I've simply input "http://" before "localhost" in the url. Hope it helps somebody.

As I understand it, default value constraints aren't part of the ISO standard, so they don't appear in INFORMATION_SCHEMA. INFORMATION_SCHEMA seems like the best choice for this kind of task because it is cross-platform, but if the information isn't available one should use the object catalog views (sys.*) instead of system table views, which are deprecated in SQL Server 2005 and later.

Below is pretty much the same as @user186476's answer. It returns the name of the default value constraint for a given column. (For non-SQL Server users, you need the name of the default in order to drop it, and if you don't name the default constraint yourself, SQL Server creates some crazy name like "DF_TableN_Colum_95AFE4B5". To make it easier to change your schema in the future, always explicitly name your constraints!)

                $record = $record + "," + '"' + $property.Value + '"' 
            }
            else{
                $record = $record + "," + $property.Value 
            }                           
    }               

        $array.add($record) | out-null  
        #write-host $record                         
}

You can view these with Process Explorer from sysinternals. Use the "Find -> Find Handle or DLL..." option and enter the pattern "\Device\NamedPipe\". It will show you which processes have which pipes open.

Besides all cited above, there are jQuery plugins that may help too:

for individual checkboxes:

• jQuery-Tristate-Checkbox-plugin: http://vanderlee.github.io/tristate/

for tree-like behavior checkboxes:

• jQuery Tristate: http://jlbruno.github.io/jQuery-Tristate-Checkbox-plugin/

EDIT Both libraries uses the 'indeterminate' checkbox attribute, since this attribute in Html5 is just for styling (https://www.w3.org/TR/2011/WD-html5-20110113/number-state.html#checkbox-state), the null value is never sent to the server (checkboxes can only have two values).

To be able to submit this value to the server, I've create hidden counterpart fields which are populated on form submission using some javascript. On the server side, you'd need to check those counterpart fields instead of original checkboxes, of course.

I've used the first library (standalone checkboxes) where it's important to:

• Initialize the checked, unchecked, indeterminate values
• use .val() function to get the actual value
• Cannot make work .state (probably my mistake)

Hope that helps.

Look at bda.cache http://pypi.python.org/pypi/bda.cache - uses ZCA and is tested with zope and bfg.

Ben has told you how to revert a merge commit, but it's very important you realize that in doing so

"...declares that you will never want the tree changes brought in by the merge. As a result, later merges will only bring in tree changes introduced by commits that are not ancestors of the previously reverted merge. This may or may not be what you want." (git-merge man page).

An article/mailing list message linked from the man page details the mechanisms and considerations that are involved. Just make sure you understand that if you revert the merge commit, you can't just merge the branch again later and expect the same changes to come back.

You should declare your method first in void initState(), so when the first time pages has been loaded, it will init your method first, hope it can help

Create your own array.

<select name="cmpPro" ng-model="test3.Product" ng-options="q for q in productArray track by q">
    <option value="" >Plans</option>
</select>

 productArray =[];
angular.forEach($scope.leadDetail, function(value,key){
    var index = $scope.productArray.indexOf(value.Product);
    if(index === -1)
    {
        $scope.productArray.push(value.Product);
    }
});

From http://www.sqlite.org/lang_createtable.html:

CREATE TABLE IF NOT EXISTS some_table (id INTEGER PRIMARY KEY AUTOINCREMENT, ...);

a simple example : http://www.dotnetspark.com/tutorial/13-42-delete-row-from-datatable.aspx

Does this work for you?

I got the same issue and this solved it for me. Perhaps this might be a fix for your problem too.

Here is the fix. Follow this link http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Go to "Fixed curl extensions" and download the extension that matches your PHP version.

Extract and copy "php_curl.dll" to the extension directory of your wamp installation. (i.e. C:\wamp\bin\php\php5.3.13\ext)

Restart Apache

Done!

Refer to: http://blog.nterms.com/2012/07/php-curl-issues-with-wamp-server-on.html

Cheers!

You've tagged this question with the ssl tag, and SSL is the answer. Curious.

I use git add --patch quite a bit and wanted something like this to avoid having to hit d all the time through the same files. I whipped up a very hacky couple of git aliases to get the job done:

[alias]
    HELPER-CHANGED-FILTERED = "!f() { git status --porcelain | cut -c4- | ( [[ \"$1\" ]] && egrep -v \"$1\" || cat ); }; f"
    ap                      = "!git add --patch -- $(git HELPER-CHANGED-FILTERED 'min.(js|css)$' || echo 'THIS_FILE_PROBABLY_DOESNT_EXIST' )"

In my case I just wanted to ignore certain minified files all the time, but you could make it use an environment variable like $GIT_EXCLUDE_PATTERN for a more general use case.

Just in case anybody has tried all the other options and you are still stuck, try right-clicking on the project folder, head over to Maven option and click the "add dependency" button. For some reason Eclipse isn't updating the dependencies manually from the pom.xml at first try.

In PHP there is a pretty good function utf8_encode() to solve this issue.

echo utf8_encode("Résumé");

//will output Résumé instead of R?sum?

Check the official PHP page.

the am giving you is the code for trigger for INSERT, UPDATE and DELETE this works fine on Microsoft SQL SERVER 2008 and onwards database i am using is Northwind

/* comment section first create a table to keep track of Insert, Delete, Update
create table Emp_Audit(
                    EmpID int,
                    Activity varchar(20),
                    DoneBy varchar(50),
                    Date_Time datetime NOT NULL DEFAULT GETDATE()
                   );

select * from Emp_Audit*/

create trigger Employee_trigger
on Employees
after UPDATE, INSERT, DELETE
as
declare @EmpID int,@user varchar(20), @activity varchar(20);
if exists(SELECT * from inserted) and exists (SELECT * from deleted)
begin
    SET @activity = 'UPDATE';
    SET @user = SYSTEM_USER;
    SELECT @EmpID = EmployeeID from inserted i;
    INSERT into Emp_Audit(EmpID,Activity, DoneBy) values (@EmpID,@activity,@user);
end

If exists (Select * from inserted) and not exists(Select * from deleted)
begin
    SET @activity = 'INSERT';
    SET @user = SYSTEM_USER;
    SELECT @EmpID = EmployeeID from inserted i;
    INSERT into Emp_Audit(EmpID,Activity, DoneBy) values(@EmpID,@activity,@user);
end

If exists(select * from deleted) and not exists(Select * from inserted)
begin 
    SET @activity = 'DELETE';
    SET @user = SYSTEM_USER;
    SELECT @EmpID = EmployeeID from deleted i;
    INSERT into Emp_Audit(EmpID,Activity, DoneBy) values(@EmpID,@activity,@user);
end

You can manage to have a pure CSS implementation with max-height

#main-image{
    max-height: 0;
    overflow: hidden;
    background: red;
   -prefix-animation: slide 1s ease 3.5s forwards;
}

@keyframes slide {
  from {max-height: 0;}
  to {max-height: 500px;}
}

You might have to also set padding, margin and border to 0, or simply padding-top, padding-bottom, margin-top and margin-bottom.

Actually my panel had this collapse state arrow icon and I tried other answers in this post , but icon position changed, so here is the solution with collapse state arrow icon.

Add this Custom CSS

 .panel-heading 
  {
   cursor: pointer;
   padding: 0;
  }

 a.accordion-toggle 
 {
  display: block;
  padding: 10px  15px;
 }

Hope helps.

If you are getting this error from the MiniProfiler in MVC then you can increase the value by setting the property MiniProfiler.Settings.MaxJsonResponseSize to the desired value. By default, this tool seems to ignore the value set in config.

MiniProfiler.Settings.MaxJsonResponseSize = 104857600;

Courtesy mvc-mini-profiler.

One other (and an even shorter) possibility. If you're inside drawRect, something like the following:

[[UIColor blackColor] setFill];
UIRectFill((CGRect){0,200,rect.size.width,1});

Option 1:

NSString *haystack = @"value:hello World:value";
NSString *haystackPrefix = @"value:";
NSString *haystackSuffix = @":value";
NSRange needleRange = NSMakeRange(haystackPrefix.length,
                                  haystack.length - haystackPrefix.length - haystackSuffix.length);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle); // -> "hello World"

Option 2:

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"^value:(.+?):value$" options:0 error:nil];
NSTextCheckingResult *match = [regex firstMatchInString:haystack options:NSAnchoredSearch range:NSMakeRange(0, haystack.length)];
NSRange needleRange = [match rangeAtIndex: 1];
NSString *needle = [haystack substringWithRange:needleRange];

This one might be a bit over the top for your rather trivial case though.

Option 3:

NSString *needle = [haystack componentsSeparatedByString:@":"][1];

This one creates three temporary strings and an array while splitting.

All snippets assume that what's searched for is actually contained in the string.

If your regex includes a variable, make sure to escape it.

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

This can be used like this

new RegExp(escapeRegExp(searchString), 'i')

Or in a mongoDb query like this

{ '$regex': escapeRegExp(searchString) }

Posted same comment here

    // A generic test function that can be configured 
    // with an arbitrary delay and to either resolve or reject
    const test = (delay, resolveSuccessfully) => new Promise((resolve, reject) => setTimeout(() => {
        console.log(`Done ${ delay }`);
        resolveSuccessfully ? resolve(`Resolved ${ delay }`) : reject(`Reject ${ delay }`)
    }, delay));

    // Our async handler function
    const handler = async () => {
        // Promise 1 runs first, but resolves last
        const p1 = test(10000, true);
        // Promise 2 run second, and also resolves
        const p2 = test(5000, true);
        // Promise 3 runs last, but completes first (with a rejection) 
        // Note the catch to trap the error immediately
        const p3 = test(1000, false).catch(e => console.log(e));
        // Await all in parallel
        const r = await Promise.all([p1, p2, p3]);
        // Display the results
        console.log(r);
    };

    // Run the handler
    handler();
    /*
    Done 1000
    Reject 1000
    Done 5000
    Done 10000
    */

Whilst setting p1, p2 and p3 is not strictly running them in parallel, they do not hold up any execution and you can trap contextual errors with a catch.

One line only ! path and line are Strings

import java.nio.file.Files;
import java.nio.file.Paths;

Files.write(Paths.get(path), lines.getBytes());

You can by hardcoding the sequence, like so:

li, li + li + li, li + li + li + li + li {
  background-color: black;
}

li + li, li + li + li + li {
  background-color: white;
}

pandas >= 1.0

Here's a chart that summarises some of the most important conversions in pandas.

Conversions to string are trivial .astype(str) and are not shown in the figure.

"Hard" versus "Soft" conversions

Note that "conversions" in this context could either refer to converting text data into their actual data type (hard conversion), or inferring more appropriate data types for data in object columns (soft conversion). To illustrate the difference, take a look at

df = pd.DataFrame({'a': ['1', '2', '3'], 'b': [4, 5, 6]}, dtype=object)
df.dtypes                                                                  

a    object
b    object
dtype: object

# Actually converts string to numeric - hard conversion
df.apply(pd.to_numeric).dtypes                                             

a    int64
b    int64
dtype: object

# Infers better data types for object data - soft conversion
df.infer_objects().dtypes                                                  

a    object  # no change
b     int64
dtype: object

# Same as infer_objects, but converts to equivalent ExtensionType
df.convert_dtypes().dtypes                                                     

I have found that using ._getexif doesn't work in higher python versions, moreover, it is a protected class and one should avoid using it if possible. After digging around the debugger this is what I found to be the best way to get the EXIF data for an image:

from PIL import Image

def get_exif(path):
    return Image.open(path).info['parsed_exif']

This returns a dictionary of all the EXIF data of an image.

Note: For Python3.x use Pillow instead of PIL

The backwards compatible version (IE9+) is

var parent = document.querySelector(selector);
Array.prototype.forEach.call(parent.children, function(child, index){
  // Do stuff
});

The es6 way is

const parent = document.querySelector(selector);
Array.from(parent.children).forEach((child, index) => {
  // Do stuff
});

coarse grained and fine grained. Both of these modes define how the cores are shared between multiple Spark tasks. As the name suggests, fine-grained mode is responsible for sharing the cores at a more granular level. Fine-grained mode has been deprecated by Spark and will soon be removed.

Only thing i found is the BetterSource extension for Safari this will show you the manipulated source of the document only downside is nothing remotely like it for Firefox

If you compile with debug symbols, you can use objdump to produce a more readable disassembly.

>objdump --help
[...]
-S, --source             Intermix source code with disassembly
-l, --line-numbers       Include line numbers and filenames in output

objdump -drwC -Mintel is nice:

• -r shows symbol names on relocations (so you'd see puts in the call instruction below)
• -R shows dynamic-linking relocations / symbol names (useful on shared libraries)
• -C demangles C++ symbol names
• -w is "wide" mode: it doesn't line-wrap the machine-code bytes
• -Mintel: use GAS/binutils MASM-like .intel_syntax noprefix syntax instead of AT&T
• -S: interleave source lines with disassembly.

You could put something like alias disas="objdump -drwCS -Mintel" in your ~/.bashrc

Example:

> gcc -g -c test.c
> objdump -d -M intel -S test.o

test.o:     file format elf32-i386


Disassembly of section .text:

00000000 <main>:
#include <stdio.h>

int main(void)
{
   0:   55                      push   ebp
   1:   89 e5                   mov    ebp,esp
   3:   83 e4 f0                and    esp,0xfffffff0
   6:   83 ec 10                sub    esp,0x10
    puts("test");
   9:   c7 04 24 00 00 00 00    mov    DWORD PTR [esp],0x0
  10:   e8 fc ff ff ff          call   11 <main+0x11>

    return 0;
  15:   b8 00 00 00 00          mov    eax,0x0
}
  1a:   c9                      leave  
  1b:   c3                      ret

Note that this isn't using -r so the call rel32=-4 isn't annotated with the puts symbol name. And looks like a broken call that jumps into the middle of the call instruction in main. Remember that the rel32 displacement in the call encoding is just a placeholder until the linker fills in a real offset (to a PLT stub in this case, unless you statically link libc).

You can determine if as certain word is found in a cell by using

If InStr(cell.Value, "Word1") > 0 Then

If Word1 is found in the string the InStr() function will return the location of the first character of Word1 in the string.

I had this problem because I installed python/pip with a weird ~/.pydistutils.cfg that I didn't remember writing. Deleted it, reinstalled (with pybrew), and everything was fine.

It will redirect your store page to your contact page

    <IfModule mod_rewrite.c>
    RewriteEngine On 
    RewriteBase /
    Redirect 301 /storepage /contactpage
    </IfModule>

If you don't mind the slashes being switched, you could [ab]use Uri:

Uri file = new Uri(@"c:\foo\bar\blop\blap.txt");
// Must end in a slash to indicate folder
Uri folder = new Uri(@"c:\foo\bar\");
string relativePath = 
Uri.UnescapeDataString(
    folder.MakeRelativeUri(file)
        .ToString()
        .Replace('/', Path.DirectorySeparatorChar)
    );

As a function/method:

string GetRelativePath(string filespec, string folder)
{
    Uri pathUri = new Uri(filespec);
    // Folders must end in a slash
    if (!folder.EndsWith(Path.DirectorySeparatorChar.ToString()))
    {
        folder += Path.DirectorySeparatorChar;
    }
    Uri folderUri = new Uri(folder);
    return Uri.UnescapeDataString(folderUri.MakeRelativeUri(pathUri).ToString().Replace('/', Path.DirectorySeparatorChar));
}

you can just do $scope.todo = Todo.get({ id: 123 }). .get() and .query() on a Resource return an object immediately and fill it with the result of the promise later (to update your template). It's not a typical promise which is why you need to either use a callback or the $promise property if you have some special code you want executed after the call. But there is no need to assign it to your scope in a callback if you are only using it in the template.

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

Version +2.0

In version +2.0 you specify the namespace/room/node you are querying against.

As with broadcasting, the default is all clients from the default namespace ('/'):

const io = require('socket.io')();  
io.clients((error, clients) => {
      if (error) throw error;
      console.log(clients); // => [6em3d4TJP8Et9EMNAAAA, G5p55dHhGgUnLUctAAAB]
});

Gets a list of client IDs connected to specific namespace (across all nodes if applicable).

const io = require('socket.io')();
io.of('/chat').clients((error, clients) => {
     if (error) throw error;
     console.log(clients); // => [PZDoMHjiu8PYfRiKAAAF, Anw2LatarvGVVXEIAAAD]
});

An example to get all clients in namespace's room:

const io = require('socket.io')();
io.of('/chat').in('general').clients((error, clients) => {
      if (error) throw error;
      console.log(clients); // => [Anw2LatarvGVVXEIAAAD] 
});

This is from the official documentation: Socket.IO Server-API

You can do it by using below CSS:

table {
  width: 100%;
  table-layout: fixed;
}

th, td {
  overflow: hidden;
  width: 200px;
  text-overflow: ellipsis;
  white-space: nowrap;
}

Here is a StackBlitz Example with Sample Data

If you want a solution without nested loops and invoking break on success you could developer a quick wrap retriable for any iterable. Here's an example of a networking issue that I run into often - saved authentication expires. The use of it would read like this:

client = get_client()
smart_loop = retriable(list_of_values):

for value in smart_loop:
    try:
        client.do_something_with(value)
    except ClientAuthExpired:
        client = get_client()
        smart_loop.retry()
        continue
    except NetworkTimeout:
        smart_loop.retry()
        continue

Use this both installation and then go ahead with your python code

pip install google-cloud    
pip install google-cloud-vision

You cannot style a text file, it must be HTML

1. install port: https://guide.macports.org/
2. install or upgrade openssl package: sudo port install openssl or sudo port upgrade openssl
3. that's it, run openssl version to see the result.

The thing to understand here is that:

The constructor ViewClassName(Context context, AttributeSet attrs ) is called when inflating the customView via xml. You see you are not using the new keyword to instantiate your object i.e. you are not doing new GhostSurfaceCameraView(). Doing this you are calling the first constructor i.e. public View (Context context).

Whereas when inflating view from XML, i.e. when using setContentView(R.layout.ghostviewscreen); or using findViewById, you, NO, not you!, the android system calls the ViewClassName(Context context, AttributeSet attrs ) constructor.

This is clear when reading the documentation : "Constructor that is called when inflating a view from XML." See: https://developer.android.com/reference/android/view/View.html#View(android.content.Context,%20android.util.AttributeSet)

Hence, never forget basic polymorphism and never forget reading through the documentation. It saves a ton of headache.

I found another issue, for some reason if the extensions are cached in the local AppData folder, the XNA extensions never get loaded.

You need to remove the files extensionSdks.en-US.cache and extensions.en-US.cache from the %LocalAppData%\Microsoft\VisualStudio\11.0\Extensions folder. These files are rebuilt the next time you launch

If you need access to the Visual Studio startup log to debug what's happening, run devenv.exe /log command from the C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE directory (assuming you are on a 64 bit machine). The log file generated is located here:

%AppData%\Microsoft\VisualStudio\11.0\ActivityLog.xml

I tried your code:

CheckedListBox cb = new CheckedListBox();
for (var i = 1; i < 11; i++)
  cb.Items.Add("Item " + i, i % 3 == 0);

string fmt = RHelper.FormatQuery(cb);
Console.WriteLine(fmt);
Console.ReadLine();

It threw an exception at this line:

foreach (DataRowView item in chekedListBox.CheckedItems)

// Unable to cast object of type 'System.String' to type 'System.Data.DataRowView'.

Maybe you are also facing the same kind of problem. Instead of casting to DataRowView, try making the following changes:

foreach (var item in chekedListBox.CheckedItems)
{
    ID = ID + item.ToString(); // item["" + FieldName + ""];

Because items in CheckedListBox are of object type.

that worked for me after clearing selection, BeginEdit and change the girdview rows and end the Edit Mode.

 if (dgvDetails.RowCount > 0)
                    {
                        dgvDetails.ClearSelection(); 
                        dgvDetails.BeginEdit(true); 
                      
                        foreach (DataGridViewRow dgvr in dgvDetails.Rows)
                        {
                            dgvr.Cells["cellName"].Value = true;
                        }
                        dgvDetails.EndEdit();
                    }

in your servlet

 request.setAttribute("submitDone","done");
 return mapping.findForward("success");

In your jsp

<c:if test="${not empty submitDone}">
  <script>alert("Form submitted");
</script></c:if>

Given this HTML:

<select>
    <option value="0">One</option>
    <option value="1">Two</option>
</select>

Select by description for jQuery v1.6+:

var text1 = 'Two';
$("select option").filter(function() {
    //may want to use $.trim in here
    return $(this).text() == text1; 
}).prop('selected', true);

For those who need to 'run as root' remotely through a script logging into a user account in the sudoers file, I found an evil horrible hack, that is no doubt very insecure:

sshpass -p 'userpass' ssh -T -p port user@server << EOSSH
sudo -S su - << RROOT
userpass
echo ""
echo "*** Got Root ***"
echo ""
#[root commands go here]
useradd -m newuser
echo "newuser:newpass" | chpasswd
RROOT
EOSSH

As of upgrading from pip 7.x.x to 8.x.x on Python 3.4 (for *.whl support).

Wrong command: pip install --upgrade pip (can't move pip.exe to temporary folder, permisson denied)

OK variant: py -3.4 -m pip install --upgrade pip (do not execute pip.exe)

My solution will be to keep text part of tool bar separate, to define style and say, center or whichever alignment. It can be done in XML itself. Some paddings can be specified after doing calculations when you have actions that are visible always. I have moved two attributes from toolbar to its child TextView.

Apparently, for certain attributes, React is intelligent enough to omit the attribute if the value you pass to it is not truthy. For example:

const InputComponent = function() {
    const required = true;
    const disabled = false;

    return (
        <input type="text" disabled={disabled} required={required} />
    );
}

will result in:

<input type="text" required>

Update: if anyone is curious as to how/why this happens, you can find details in ReactDOM's source code, specifically at lines 30 and 167 of the DOMProperty.js file.

The solution that fixed mine was that I had inadvertently applied different keys to Encryption and Decryption methods.

It is same way as you do for the two divs, just float the third one to left or right too.

<style>
  .left{float:left; width:33%;}
</style>

<div class="left">...</div>
<div class="left">...</div>
<div class="left">...</div>

Try this

If you are deploying your app into the root context (e.g. https://myapp.com/), set the base URL to /:

<head>
  <base href="/">
  ...
</head>

Angular Documentation

I use JuJu which basically allows to have a really tiny linux distribution (containing just the package manager) inside your $HOME/.juju directory.

It allows to have your custom system inside the home directory accessible via proot and, therefore, you can install any packages without root privileges. It will run properly to all the major linux distributions, the only limitation is that JuJu can run on linux kernel with minimum reccomended version 2.6.32.

For instance, after installed JuJu to install pip just type the following:

$>juju -f
(juju)$> pacman -S python-pip
(juju)> pip

The following might be helpful for RecyclerView with Single Choice.

Three steps to do that, 1) Declare a global integer variable,

private int mSelectedItem = -1;

2) in onBindViewHolder

 mRadio.setChecked(position == mSelectedItem);

3) in onClickListener

mSelectedItem = getAdapterPosition();
notifyItemRangeChanged(0, mSingleCheckList.size());
mAdapter.onItemHolderClick(SingleCheckViewHolder.this);

TL;DR

a) the method/function only reads the array argument => implicit (internal) reference
b) the method/function modifies the array argument => value
c) the method/function array argument is explicitly marked as a reference (with an ampersand) => explicit (user-land) reference

Or this:
- non-ampersand array param: passed by reference; the writing operations alter a new copy of the array, copy which is created on the first write;
- ampersand array param: passed by reference; the writing operations alter the original array.

Remember - PHP does a value-copy the moment you write to the non-ampersand array param. That's what copy-on-write means. I'd love to show you the C source of this behaviour, but it's scary in there. Better use xdebug_debug_zval().

Pascal MARTIN was right. Kosta Kontos was even more so.

Answer

It depends.

Long version

I think I'm writing this down for myself. I should have a blog or something...

Whenever people talk of references (or pointers, for that matter), they usually end up in a logomachy (just look at this thread!).
PHP being a venerable language, I thought I should add up to the confusion (even though this a summary of the above answers). Because, although two people can be right at the same time, you're better off just cracking their heads together into one answer.

First off, you should know that you're not a pedant if you don't answer in a black-and-white manner. Things are more complicated than "yes/no".

As you will see, the whole by-value/by-reference thing is very much related to what exactly are you doing with that array in your method/function scope: reading it or modifying it?

What does PHP says? (aka "change-wise")

The manual says this (emphasis mine):

By default, function arguments are passed by value (so that if the value of the argument within the function is changed, it does not get changed outside of the function). To allow a function to modify its arguments, they must be passed by reference.

To have an argument to a function always passed by reference, prepend an ampersand (&) to the argument name in the function definition

As far as I can tell, when big, serious, honest-to-God programmers talk about references, they usually talk about altering the value of that reference. And that's exactly what the manual talks about: hey, if you want to CHANGE the value in a function, consider that PHP's doing "pass-by-value".

There's another case that they don't mention, though: what if I don't change anything - just read?
What if you pass an array to a method which doesn't explicitly marks a reference, and we don't change that array in the function scope? E.g.:

<?php
function readAndDoStuffWithAnArray($array) 
{
    return $array[0] + $array[1] + $array[2];
}

$x = array(1, 2, 3);

echo readAndDoStuffWithAnArray($x);

Read on, my fellow traveller.

What does PHP actually do? (aka "memory-wise")

The same big and serious programmers, when they get even more serious, they talk about "memory optimizations" in regards to references. So does PHP. Because PHP is a dynamic, loosely typed language, that uses copy-on-write and reference counting, that's why.

It wouldn't be ideal to pass HUGE arrays to various functions, and PHP to make copies of them (that's what "pass-by-value" does, after all):

<?php

// filling an array with 10000 elements of int 1
// let's say it grabs 3 mb from your RAM
$x = array_fill(0, 10000, 1); 

// pass by value, right? RIGHT?
function readArray($arr) { // <-- a new symbol (variable) gets created here
    echo count($arr); // let's just read the array
}

readArray($x);

Well now, if this actually was pass-by-value, we'd have some 3mb+ RAM gone, because there are two copies of that array, right?

Wrong. As long as we don't change the $arr variable, that's a reference, memory-wise. You just don't see it. That's why PHP mentions user-land references when talking about &$someVar, to distinguish between internal and explicit (with ampersand) ones.

Facts

So, when an array is passed as an argument to a method or function is it passed by reference?

I came up with three (yeah, three) cases:
a) the method/function only reads the array argument
b) the method/function modifies the array argument
c) the method/function array argument is explicitly marked as a reference (with an ampersand)

Firstly, let's see how much memory that array actually eats (run here):

<?php
$start_memory = memory_get_usage();
$x = array_fill(0, 10000, 1);
echo memory_get_usage() - $start_memory; // 1331840

That many bytes. Great.

a) the method/function only reads the array argument

Now let's make a function which only reads the said array as an argument and we'll see how much memory the reading logic takes:

<?php

function printUsedMemory($arr) 
{
    $start_memory = memory_get_usage();

    count($arr);       // read
    $x = $arr[0];      // read (+ minor assignment)
    $arr[0] - $arr[1]; // read

    echo memory_get_usage() - $start_memory; // let's see the memory used whilst reading
}

$x = array_fill(0, 10000, 1); // this is 1331840 bytes
printUsedMemory($x);

Wanna guess? I get 80! See for yourself. This is the part that the PHP manual omits. If the $arr param was actually passed-by-value, you'd see something similar to 1331840 bytes. It seems that $arr behaves like a reference, doesn't it? That's because it is a references - an internal one.

b) the method/function modifies the array argument

Now, let's write to that param, instead of reading from it:

<?php

function printUsedMemory($arr)
{
    $start_memory = memory_get_usage();

    $arr[0] = 1; // WRITE!

    echo memory_get_usage() - $start_memory; // let's see the memory used whilst reading
}

$x = array_fill(0, 10000, 1);
printUsedMemory($x);

Again, see for yourself, but, for me, that's pretty close to being 1331840. So in this case, the array is actually being copied to $arr.

c) the method/function array argument is explicitly marked as a reference (with an ampersand)

Now let's see how much memory a write operation to an explicit reference takes (run here) - note the ampersand in the function signature:

<?php

function printUsedMemory(&$arr) // <----- explicit, user-land, pass-by-reference
{
    $start_memory = memory_get_usage();

    $arr[0] = 1; // WRITE!

    echo memory_get_usage() - $start_memory; // let's see the memory used whilst reading
}

$x = array_fill(0, 10000, 1);
printUsedMemory($x);

My bet is that you get 200 max! So this eats approximately as much memory as reading from a non-ampersand param.

I did it with an ajax post and then returned using a data url:

$(document).ready(function () {
    var exportClick = function () {
        $.ajax({
           url: "/api/test.php",
           type: "POST",
           dataType: "text",
           data: {
              action: "getCSV",
              filter: "name = 'smith'",
           },
           success: function(data) {
              var w = window.open('data:text/csv;charset=utf-8,' + encodeURIComponent(data));
              w.focus();
           },
           error: function () {
              alert('Problem getting data');
           },
        });
    }
});

echo $items[array_rand($items)];

array_rand()

I'm very surprised no one has mentioned this one liner. It's simple, concise and performs slightly better than str.split(target, -1).length-1

public static int count(String str, String target) {
    return (str.length() - str.replace(target, "").length()) / target.length();
}

In case you are in control of the Server that sends the content of the iframe you can set the setting for X-Frame-Options in your webserver.

Configuring Apache

To send the X-Frame-Options header for all pages, add this to your site's configuration:

Header always append X-Frame-Options SAMEORIGIN

Configuring nginx

To configure nginx to send the X-Frame-Options header, add this either to your http, server or location configuration:

add_header X-Frame-Options SAMEORIGIN;

No configuration

This header option is optional, so if the option is not set at all, you will give the option to configure this to the next instance (e.g. the visitors browser or a proxy)

source: https://developer.mozilla.org/en-US/docs/Web/HTTP/X-Frame-Options

This is an old question but still answering it in present-day context as many of the above answers may not work now.

The problem is that the Path is still pointing to the old version. Two solutions can be provided for resolution :

1. Uninstall old version of openssl package brew uninstall openssl and then reinstall the new version : brew install openssl
2. point the PATH to the new version of openssl.First install the new version and now(or if) you have installed the latest version, point the path to it: echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

Apache

In Apache, you can add the woff2 mime type via your .htaccess file as stated by this link.

AddType  application/font-woff2  .woff2

IIS

In IIS, simply add the following mimeMap tag into your web.config file inside the staticContent tag.

<configuration>
  <system.webServer>
    <staticContent>
      <mimeMap fileExtension=".woff2" mimeType="application/font-woff2" />

You can create a delay using the following example

setInterval(function(){alert("Hello")},3000);

Replace 3000 with # of milliseconds

You can place the content of what you want executed inside the function.

Merging two array will not remove the duplicate you can try the below example to get unique from two array

$a1=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow");
$a2=array("e"=>"red","f"=>"green","g"=>"blue");

$result=array_diff($a1,$a2);
print_r($result);

html:

<h4 data-toggle-selector="#me">toggle</h4>
<div id="me">content here</div>

js:

$(function () {
    $('[data-toggle-selector]').on('click',function () {
        $($(this).data('toggle-selector')).toggle(300);
    })
})

With jquery :

$("#reset").on("click", function() {
    $('#my_select').val($('#my_select').find('option[selected="selected"]').val());
}

You can set a callback function for the onSubmit event of the form and check the contents of each field. If it contains nothing you can then fill it with the string "empty":

<form name="my_form" action="validate.php" onsubmit="check()">
    <input type="text" name="text1" />
    <input type="submit" value="submit" />
</form>

and in your js:

function check() {
    if(document.forms["my_form"]["text1"].value == "")
        document.forms["my_form"]["text1"].value = "empty";
}

I Think This will be helpful

See this pure Python ping by Matthew Dixon Cowles and Jens Diemer. Also, remember that Python requires root to spawn ICMP (i.e. ping) sockets in linux.

import ping, socket
try:
    ping.verbose_ping('www.google.com', count=3)
    delay = ping.Ping('www.wikipedia.org', timeout=2000).do()
except socket.error, e:
    print "Ping Error:", e

The source code itself is easy to read, see the implementations of verbose_ping and of Ping.do for inspiration.

I would definitely recommend that you install Anaconda and then use the "pip install seaborn" command from the Lab Jupyter IDE. It should work. It seems that the package is already pre-installed on Lab Jupyter.

(Windows 8) In my case i have changed default RAM from 1GB to 2GB on Genymotion and it gave this error. When i changed it back to 1GB it worked.

Try this:

item.shipping!==undefined

<TextView
 android:id="@+id/phoneNumber"
 android:autoLink="phone"
 android:linksClickable="true"
 android:text="+91 22 2222 2222"
 />

This is how you can open EditText label assigned number on dialer directly.

No one should ever have to keep writing app.use('/someRoute', require('someFile')) until it forms a heap of code.

It just doesn't make sense at all to be spending time invoking/defining routings. Even if you do need custom control, it's probably only for some of the time, and for the most bit you want to be able to just create a standard file structure of routings and have a module do it automatically.

Try Route Magic

As you scale your app, the routing invocations will start to form a giant heap of code that serves no purpose. You want to do just 2 lines of code to handle all the app.use routing invocations with Route Magic like this:

const magic = require('express-routemagic')
magic.use(app, __dirname, '[your route directory]')

For those you want to handle manually, just don't use pass the directory to Magic.

The php.js project has JavaScript implementations of many of PHP's functions. base64_encode and base64_decode are included.

This is like user3076252's answer, but you'll be choosing a different set of options:

• Project > Properties > Java Build Path
• Select Libraries tab > Alternate JRE > Installed JREs...
• Click "Search." Unless you know the exact folder name, you should choose a drive to search.

It should find your unbound JRE, but this time with all the numbers in it's name (rather than unbound), and you can select it. It will take a while to search the drive, but you can stop it at any time, and it will save the results, if any.

Old style string formatting:

In [3]: "%02x" % 127
Out[3]: '7f'

New style

In [7]: '{:x}'.format(127)
Out[7]: '7f'

Using capital letters as format characters yields uppercase hexadecimal

In [8]: '{:X}'.format(127)
Out[8]: '7F'

This is a BUG reported in launchpad, but there is a workaround :

Run this to see where these files are located

$ find /usr/ -name crti*
/usr/lib/x86_64-linux-gnu/crti.o

then add this path to LIBRARY_PATH variable

$ export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LIBRARY_PATH

I selected columns that I want to delete 0 values then clicked DATA > FILTER. In column's header there is a filter icon appears. I clicked on that icon and selected only 0 values and clicked OK. Only 0 values becomes selected. Finally clear content OR use DELETE button. Problem Solved!

So we make a function that takes in a literal string, and the array we want to look through. it returns a new array with the matches found. We create a new regexp object inside this function and then execute a String.search on each element element in the array. If found, it pushes the string into a new array and returns.

// literal_string: a regex search, like /thisword/ig
// target_arr: the array you want to search /thisword/ig for.

function arr_grep(literal_string, target_arr) {
  var match_bin = [];
  // o_regex: a new regex object.
  var o_regex = new RegExp(literal_string);
  for (var i = 0; i < target_arr.length; i++) {
    //loop through array. regex search each element.
    var test = String(target_arr[i]).search(o_regex);
    if (test > -1) {
    // if found push the element@index into our matchbin.
    match_bin.push(target_arr[i]);
    }
  }
  return match_bin;
}

// arr_grep(/.*this_word.*/ig, someArray)

This is pretty much what the generic method Value() is for. You get exactly the behavior you want if you combine it with nullable value types and the ?? operator:

width = jToken.Value<double?>("width") ?? 100;

I was struggling for a while with this as my work computer (with Windows 10) created the default user library on a network drive, which would slow down R and RStudio to an unusable state.

In case this helps someone, this is the easiest way I found, without requiring admin rights:

• make sure the directory you want to install your packages into exists. If you want to respect the convention, use: C:\Users\username\R\win-library\rversion (for example, something like: C:\Users\janebloggs\R\win-library\3.6)
• create a .Renviron file in your home directory (which might be on the network drive?), and in it, write one single line that defines the R_LIBS_USER variable to be your custom path:

(feel free to add comments too, with lines starting with #)

If a .Renviron file exists, R will read it at startup and use the variables as they are defined in there, before running the code in the .Rprofile. You can read about it in help(Startup).

Now it should be persistent between sessions!

My gut told me the same thing when I came across this design.

I am working on a code base where there are three dbContexts to one database. 2 out of the 3 dbcontexts are dependent on information from 1 dbcontext because it serves up the administrative data. This design has placed constraints on how you can query your data. I ran into this problem where you cannot join across dbcontexts. Instead what you are required to do is query the two separate dbcontexts then do a join in memory or iterate through both to get the combination of the two as a result set. The problem with that is instead of querying for a specific result set you are now loading all your records into memory and then doing a join against the two result sets in memory. It can really slow things down.

I would ask the question "just because you can, should you?"

See this article for the problem I came across related to this design. The specified LINQ expression contains references to queries that are associated with different contexts

I prefer this syntaxis:

$query = "INSERT INTO myTable SET fname='Fname',lname='Lname',website='Website'";

My favorite function for entropy is the following:

def entropy(labels):
    prob_dict = {x:labels.count(x)/len(labels) for x in labels}
    probs = np.array(list(prob_dict.values()))

    return - probs.dot(np.log2(probs))

I am still looking for a nicer way to avoid the dict -> values -> list -> np.array conversion. Will comment again if I found it.

Saudate, I ran across this looking for a different problem. You most definitely can use the Sql Server Import wizard to import data into a new table. Of course, you do not wish to leave that table in the database, so my suggesting is that you import into a new table, then script the data in query manager to insert into the existing table. You can add a line to drop the temp table created by the import wizard as the last step upon successful completion of the script.

I believe your original issue is in fact related to Sql Server 64 bit and is due to your having a 32 bit Excel and these drivers don't play well together. I did run into a very similar issue when first using 64 bit excel.

A problem with using DateTime.TryParse is that it doesn't support the very common data-entry use case of dates entered without separators, e.g. 011508.

Here's an example of how to support this. (This is from a framework I'm building, so its signature is a little weird, but the core logic should be usable):

    private static readonly Regex ShortDate = new Regex(@"^\d{6}$");
    private static readonly Regex LongDate = new Regex(@"^\d{8}$");

    public object Parse(object value, out string message)
    {
        msg = null;
        string s = value.ToString().Trim();
        if (s.Trim() == "")
        {
            return null;
        }
        else
        {
            if (ShortDate.Match(s).Success)
            {
                s = s.Substring(0, 2) + "/" + s.Substring(2, 2) + "/" + s.Substring(4, 2);
            }
            if (LongDate.Match(s).Success)
            {
                s = s.Substring(0, 2) + "/" + s.Substring(2, 2) + "/" + s.Substring(4, 4);
            }
            DateTime d = DateTime.MinValue;
            if (DateTime.TryParse(s, out d))
            {
                return d;
            }
            else
            {
                message = String.Format("\"{0}\" is not a valid date.", s);
                return null;
            }
        }

    }

You have to create a derived table for the distinct columns and then query the count from that table:

SELECT COUNT(*) 
FROM (SELECT DISTINCT column1,column2
      FROM  tablename  
      WHERE condition ) as dt

Here dt is a derived table.

Please find the code below for Vlookup:

Function vlookupVBA(lookupValue, rangeString, colOffset)
vlookupVBA = "#N/A"
On Error Resume Next
Dim table_lookup As range
Set table_lookup = range(rangeString)
vlookupVBA = Application.WorksheetFunction.vlookup(lookupValue, table_lookup, colOffset, False)
End Function

I wrote a file extraction tool to be used in Linux, that can extract about 20 different file formats and uses the file content, not the file name.

This tool got quite popular, I have a regular stream of people who download it from my blog. Get it here:

• E - Extract Any Archive

Create the hash:

hash = {:item1 => 1}

Add a new item to it:

hash[:item2] = 2

As described here: Angular NgModelController, you should provide the <input with the required controller ngModel

<input submit-required="true" ng-model="user.Name"></input>

There's many ways to do this.

Two examples:

 $str = (string) $int;
 $str = "$int";     

See the PHP Manual on Types Juggling for more.

This is how I do it.

try:
    do_something()
except:
    # How can I log my exception here, complete with its traceback?
    import traceback
    traceback.format_exc() # this will print a complete trace to stout.

Basic difference : a 8-bit PNG comprises a max. of 256 colors. PNG-24 is a loss-less format and can contain up to 16 million colors.

Impacts:

1. If you are using any round corner image then edges might visible in png8 format.
2. ie6 doesnt support png24 format.

You can use setCompoundDrawablesWithIntrinsicBounds(int left, int top, int right, int bottom)

set 0 where you don't want images

Example for Drawable on the left:

TextView textView = (TextView) findViewById(R.id.myTxtView);
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon, 0, 0, 0);

Alternatively, you can use setCompoundDrawablesRelativeWithIntrinsicBounds to respect RTL/LTR layouts.

Tip: Whenever you know any XML attribute but don't have clue about how to use it at runtime. just go to the description of that property in developer doc. There you will find Related Methods if it's supported at runtime . i.e. For DrawableLeft

Check if there is any zombie process using "top" command.

docker ps | grep <<container name>> 

Get the container id.

ps -ef | grep <<container id>>

ps -ef|grep defunct | grep java

And kill the container by Parent PID .

Made a category like mxcl, but this is slightly faster.

My testing shows ~15% improvement (I could be wrong, feel free to compare the two yourself).

Basically I take the portion of the array thats in front of the object and the portion behind and combine them. Thus excluding the element.

- (NSArray *)prefix_arrayByRemovingObject:(id)object 
{
    if (!object) {
        return self;
    }

    NSUInteger indexOfObject = [self indexOfObject:object];
    NSArray *firstSubArray = [self subarrayWithRange:NSMakeRange(0, indexOfObject)];
    NSArray *secondSubArray = [self subarrayWithRange:NSMakeRange(indexOfObject + 1, self.count - indexOfObject - 1)];
    NSArray *newArray = [firstSubArray arrayByAddingObjectsFromArray:secondSubArray];

    return newArray;
}

Use LayoutParams. If you are using a LinearLayout you have to import android.widget.LinearLayout.LayoutParams, else import the proper version of LayoutParams for the layout you're using, or it will cause a ClassCastException, then:

LayoutParams layoutParams = new LayoutParams(int width, int height);
layoutParams.setMargins(int left, int top, int right, int bottom);
imageView.setLayoutParams(layoutParams);

NB: Note that you can use also imageView.setLeft(int dim), BUT THIS WON'T set the position of the component, it will set only the position of the left border of the component, the rest will remain at the same position.

Upgrade to React Native 0.58.5 or higher version. They have includeSubdomain in their config files in RN 0.58.5.

ChangeLog

In Rn 0.58.5 they have declared network_security_config with their server domain. Network security configuration allows an app to permit cleartext traffic from a certain domain. So no need to put extra effort by declaring android:usesCleartextTraffic="true" in the application tag of your manifest file. It will be resolved automatically after upgrading the RN Version.

This is because the CHARINDEX-1 is returning a -ive value if the look-up for " " (space) is 0. The simplest solution would be to avoid '-ve' by adding

ABS(CHARINDEX(' ', PostCode ) -1))

which will return only +ive values for your length even if CHARINDEX(' ', PostCode ) -1) is a -ve value. Correct me if I'm wrong!

I experienced a similar issue in Visual Studio, which was being caused by an incorrect url() path to the font in question.

I stopped getting this error after changing (for instance):

to this:

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),

This error tells you that you do not have the razor engine properly associated with your project.

Solution: In the Solution Explorer window right click on your web project and select "Manage Nuget Packages..." then install "Microsoft ASP.NET Razor". This will make sure that the properly package is installed and it will add the necessary entries into your web.config file.

Based on Agus's function, but I prefer return just the match values:

var bob = "> bob <";
function matchAll(str, regex) {
    var res = [];
    var m;
    if (regex.global) {
        while (m = regex.exec(str)) {
            res.push(m[1]);
        }
    } else {
        if (m = regex.exec(str)) {
            res.push(m[1]);
        }
    }
    return res;
}
var Amatch = matchAll(bob, /(&.*?;)/g);
console.log(Amatch);  // yeilds: [>, <]

I did not know the answer so asked the ASP.NET team here.

So the trick is to change the signature to HttpResponseMessage and use Request.CreateResponse.

[ResponseType(typeof(User))]
public HttpResponseMessage GetUser(HttpRequestMessage request, int userId, DateTime lastModifiedAtClient)
{
    var user = new DataEntities().Users.First(p => p.Id == userId);
    if (user.LastModified <= lastModifiedAtClient)
    {
         return new HttpResponseMessage(HttpStatusCode.NotModified);
    }
    return request.CreateResponse(HttpStatusCode.OK, user);
}

Based on muhuk answer I did this simple tag encapsulating python string.format method.

• Create a templatetags at your's application folder.
• Create a format.py file on it.

• Add this to it:

  from django import template
  
  register = template.Library()
  
  @register.filter(name='format')
  def format(value, fmt):
      return fmt.format(value)
  

• Load it in your template {% load format %}
• Use it. {{ some_value|format:"{:0.2f}" }}

As Moneer Kamal said, you can do that simply:

SELECT id, client_id FROM order 
WHERE rownum <= 100
ORDER BY create_time DESC;

Notice that the ordering is done after getting the 100 row. This might be useful for who does not want ordering.

For MySQL 5.7 on Mac OS X El Capitan:

OS X provides example configuration files at /usr/local/mysql/support-files/my-default.cnf

To add variables, first stop the server and just copy above file to, /usr/local/mysql/etc/my.cnf

cmd : sudo cp /usr/local/mysql/support-files/my-default.cnf /usr/local/mysql/etc/my.cnf

NOTE: create 'etc' folder under 'mysql' in case it doesn't exists.

cmd : sudo mkdir /usr/local/mysql/etc

Once the my.cnf is created under etc. it's time to set variable inside that.

cmd: sudo nano my.cnf

set variables below [mysqld]

[mysqld]
innodb_log_file_size = 512M
innodb_strict_mode = 0

now start a server!

Alright this is very late however I've discovered that if you add a List View under your edit text then the keyboard will move all layouts under that edittext without moving the ListView

<EditText
android:id="@+id/et"
android:layout_height="match_parent"
android:layout_width="match_parent"



/>

<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"//can make as 1dp
    android:layout_below="@+id/et" // set to below editext
    android:id="@+id/view"
    >
**<any layout**

This is the only solution that worked for me.

I found json_reformat to be very handy. So I just did the following:

curl http://127.0.0.1:5000/people/api.json | json_reformat

that's it!

In Python, you can do:

test = float("inf")

In Python 3.5, you can do:

import math
test = math.inf

And then:

test > 1
test > 10000
test > x

Will always be true. Unless of course, as pointed out, x is also infinity or "nan" ("not a number").

Additionally (Python 2.x ONLY), in a comparison to Ellipsis, float(inf) is lesser, e.g:

float('inf') < Ellipsis

would return true.

You need to do this:

var scope = {
     splitterStyle: {
         height: 100
     }
};

And then apply this styling to the required elements:

<div id="horizontal" style={splitterStyle}>

In your code you are doing this (which is incorrect):

<div id="horizontal" style={height}>

Where height = 100.

In Access, click Create > Module and paste in the following code

Public Function ConvertMyStringToDateTime(strIn As String) As Date
ConvertMyStringToDateTime = CDate( _
        Mid(strIn, 1, 4) & "-" & Mid(strIn, 5, 2) & "-" & Mid(strIn, 7, 2) & " " & _
        Mid(strIn, 9, 2) & ":" & Mid(strIn, 11, 2) & ":" & Mid(strIn, 13, 2))
End Function

Hit Ctrl+S and save the module as modDateConversion.

Now try using a query like

Select * from Events
Where Events.[Date] > ConvertMyStringToDateTime("20130423014854")

--- Edit ---

Alternative solution avoiding user-defined VBA function:

SELECT * FROM Events
WHERE Format(Events.[Date],'yyyyMMddHhNnSs') > '20130423014854'

You need to split the line first.

import csv

with open('log.txt', 'r') as in_file:
    stripped = (line.strip() for line in in_file)
    lines = (line.split(",") for line in stripped if line)
    with open('log.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('title', 'intro'))
        writer.writerows(lines)

First of all, a modified version of your service.

a )

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

app.factory('ExampleService',function(){
    return {
        f1 : function(world){
            return 'Hello' + world;
        }
    };
});

This returns an object, nothing to new here.

Now the way to get this from the console is

b )

var $inj = angular.injector(['app']);
var serv = $inj.get('ExampleService');
serv.f1("World");

c )

One of the things you were doing there earlier was to assume that the app.factory returns you the function itself or a new'ed version of it. Which is not the case. In order to get a constructor you would either have to do

app.factory('ExampleService',function(){
        return function(){
            this.f1 = function(world){
                return 'Hello' + world;
            }
        };
    });

This returns an ExampleService constructor which you will next have to do a 'new' on.

Or alternatively,

app.service('ExampleService',function(){
            this.f1 = function(world){
                return 'Hello' + world;
            };
    });

This returns new ExampleService() on injection.

When calling the callback function, we could use it like below:

consumingFunction(callbackFunctionName)

Example:

// Callback function only know the action,
// but don't know what's the data.
function callbackFunction(unknown) {
  console.log(unknown);
}

// This is a consuming function.
function getInfo(thenCallback) {
  // When we define the function we only know the data but not
  // the action. The action will be deferred until excecuting.
  var info = 'I know now';
  if (typeof thenCallback === 'function') {
    thenCallback(info);    
  }
}

// Start.
getInfo(callbackFunction); // I know now

This is the Codepend with full example.

I looked at using KeychainItemWrapper (the ARC version) but I didn't find its Objective C wrapper as wholesome as desired.

I used this solution by Kishikawa Katsumi, which meant I wrote less code and didn't have to use casts to store NSString values.

Two examples of storing:

[UICKeyChainStore setString:@"kishikawakatsumi" forKey:@"username"];
[UICKeyChainStore setString:@"P455_w0rd$1$G$Z$" forKey:@"password"];

Two examples of retrieving

UICKeyChainStore *store = [UICKeyChainStore keyChainStore];
    // or
UICKeyChainStore *store = [UICKeyChainStore keyChainStoreWithService:@"YOUR_SERVICE"];

NSString *username = [store stringForKey:@"username"];
NSString *password = [store stringForKey:@"password"];

If you want to upload the file /Applications/XAMPP/htdocs/keypairfile.pem to ec2-user@publicdns:/var/www/html, you can simply do:

scp -Cr /Applications/XAMPP/htdocs/keypairfile.pem/uploads/ ec2-user@publicdns:/var/www/html/

Where:

• -C - Compress data
• -r - Recursive

You might want to take a look at the excellent HTTP Python library called Requests. It makes every task involving HTTP a bit easier than urllib2. From Cookies section of quickstart guide:

To send your own cookies to the server, you can use the cookies parameter:

>>> cookies = dict(cookies_are='working')

>>> r = requests.get('http://httpbin.org/cookies', cookies=cookies)
>>> r.text
'{"cookies": {"cookies_are": "working"}}'

setTimeout(expression, timeout); runs the code/function once after the timeout.

setInterval(expression, timeout); runs the code/function in intervals, with the length of the timeout between them.

Example:

var intervalID = setInterval(alert, 1000); // Will alert every second.
// clearInterval(intervalID); // Will clear the timer.

setTimeout(alert, 1000); // Will alert once, after a second.

If you need a lot of decimal numbers, in this example 17, I share with you MySql code:

This is the calculate:

=(9/1147)*100

SELECT TRUNCATE(((CAST(9 AS DECIMAL(30,20))/1147)*100),17);

This should fix your problem:

docker-compose ps # lists all services (id, name)
docker-compose stop <id/name> #this will stop only the selected container
docker-compose rm <id/name> # this will remove the docker container permanently 
docker-compose up # builds/rebuilds all not already built container 

You can also use synchronized keyword for addFinisher method like this

    //Implement the one method in the RaceListener interface
    public synchronized void addFinisher(RaceCar finisher) {
        finishingOrder.add(finisher);
    }

So you can use ArrayList add method thread-safe with this way.

Just to fix the error to set current time

from django.utils import timezone
import datetime

datetime.datetime.now(tz=timezone.utc) # you can use this value

Another option is to use JavaConfig. Assuming that all stages are already registered as spring beans you just have to:

@Autowired
private List<Stage> stages;

and spring will automatically inject them into this list. If you need to preserve order (upper solution doesn't do that) you can do it in that way:

@Configuration
public class MyConfiguration {
  @Autowired
  private Stage1 stage1;

  @Autowired
  private Stage2 stage2;

  @Bean
  public List<Stage> stages() {
    return Lists.newArrayList(stage1, stage2);
  }
}

The other solution to preserve order is use a @Order annotation on beans. Then list will contain beans ordered by ascending annotation value.

@Bean
@Order(1)
public Stage stage1() {
    return new Stage1();
}

@Bean
@Order(2)
public Stage stage2() {
    return new Stage2();
}

As php.net/foreach points out:

Unless the array is referenced, foreach operates on a copy of the specified array and not the array itself. foreach has some side effects on the array pointer. Don't rely on the array pointer during or after the foreach without resetting it.

In other words - it's not a very good idea to do what you're asking to do. Perhaps it would be a good idea to talk with someone about why you're trying to do this, see if there's a better solution? Feel free to ask us in ##PHP on irc.freenode.net if you don't have any other resources available.

string InstallPath = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\MyApplication\AppPath", "Installed", null);    
if (InstallPath != null)
{
    // Do stuff
}

That code should get your value. You'll need to be

using Microsoft.Win32;

for that to work though.

What I did was to create an extension to UITextField and added a Designer editable property. Setting this property to any color would change the border (bottom) to that color (setting other borders to none).

Since this also requires to change the place holder text color, I also added that to the extension.

    extension UITextField {

    @IBInspectable var placeHolderColor: UIColor? {
        get {
            return self.placeHolderColor
        }
        set {
            self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSForegroundColorAttributeName: newValue!])
        }
    }


    @IBInspectable var bottomBorderColor: UIColor? {
        get {
            return self.bottomBorderColor
        }
        set {
            self.borderStyle = UITextBorderStyle.None;
            let border = CALayer()
            let width = CGFloat(0.5)
            border.borderColor = newValue?.CGColor
            border.frame = CGRect(x: 0, y: self.frame.size.height - width,   width:  self.frame.size.width, height: self.frame.size.height)

            border.borderWidth = width
            self.layer.addSublayer(border)
            self.layer.masksToBounds = true

        }
    }
}

You are printing the enum object. Use the .value attribute if you wanted just to print that:

print(D.x.value)

See the Programmatic access to enumeration members and their attributes section:

If you have an enum member and need its name or value:

>>>
>>> member = Color.red
>>> member.name
'red'
>>> member.value
1

You could add a __str__ method to your enum, if all you wanted was to provide a custom string representation:

class D(Enum):
    def __str__(self):
        return str(self.value)

    x = 1
    y = 2

Demo:

>>> from enum import Enum
>>> class D(Enum):
...     def __str__(self):
...         return str(self.value)
...     x = 1
...     y = 2
... 
>>> D.x
<D.x: 1>
>>> print(D.x)
1

I think you conclusions are correct but not accurate.

As the docs indicates, socket.recv is majorly focused on the network buffers.

When socket is blocking, socket.recv will return as long as the network buffers have bytes. If bytes in the network buffers are more than socket.recv can handle, it will return the maximum number of bytes it can handle. If bytes in the network buffers are less than socket.recv can handle, it will return all the bytes in the network buffers.

You can use For Commad,to get list of Arg.

Help : For /? Help : Setlocal /?

Here is my way =

@echo off
::For Run Use This = cmd /c ""Args.cmd" Hello USER Scientist etc"
setlocal EnableDelayedExpansion
set /a Count=0
for %%I IN (%*) DO (
 Echo Arg_!Count! = %%I
 set /a Count+=1 
)
Echo Count Of Args = !Count!
Endlocal

Do not need Shift command.

This is my solution, may be it can helps I use IntelliJ IDE. File -> Setting -> Maven -> Importing change JDK for importer to 1.8( you can change to lower, higher)

I had issue with the solutions mentioned above as specifying the string key would give me javax.el.PropertyNotFoundException. The code shown below worked for me. In this I used status to count the index of for each loop and displayed the value of index I am interested on

<c:forEach items="${requestScope.key}"  var="map" varStatus="status" >
    <c:if test="${status.index eq 1}">
        <option><c:out value=${map.value}/></option>
    </c:if>
</c:forEach>    

"alternate shell" doesn't seem to work anymore in recent versions of Windows, RemoteApp is the way to go.

remoteapplicationmode:i:1
remoteapplicationname:s:Purpose of the app shown to user...
remoteapplicationprogram:s:C:\...\some.exe
remoteapplicationcmdline:s:

To get this to work under e.g. Windows 10 Professional, one needs to enable some policy:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services]
"fAllowUnlistedRemotePrograms"=dword:00000001

To watch out the runtime changes in value of a custom directive, use $observe method of attrs object, instead of putting $watch inside a custom directive. Here is the documentation for the same ... $observe docs

Also I think if_exists was used like:

Hi ${userName?if_exists}, How are you?

which will not break if userName is null, the result if null would be:

Hi , How are you?

if_exists is now deprecated and has been replaced with the default operator ! as in

Hi ${userName!}, How are you?

the default operator also supports a default value, such as:

Hi ${userName!"John Doe"}, How are you?

It depends on the used compiler.

For example, Windows' definition can be WIN32 or _WIN32.

And Linux' definition can be UNIX or __unix__ or LINUX or __linux__.

You should use readfile():

readfile("/path/to/file");

This will read the file and send it to the browser in one command. This is essentially the same as:

echo file_get_contents("/path/to/file");

except that file_get_contents() may cause the script to crash for large files, while readfile() won't.

You need to escape the dot if you want to split on a literal dot:

String extensionRemoved = filename.split("\\.")[0];

Otherwise you are splitting on the regex ., which means "any character".
Note the double backslash needed to create a single backslash in the regex.

You're getting an ArrayIndexOutOfBoundsException because your input string is just a dot, ie ".", which is an edge case that produces an empty array when split on dot; split(regex) removes all trailing blanks from the result, but since splitting a dot on a dot leaves only two blanks, after trailing blanks are removed you're left with an empty array.

To avoid getting an ArrayIndexOutOfBoundsException for this edge case, use the overloaded version of split(regex, limit), which has a second parameter that is the size limit for the resulting array. When limit is negative, the behaviour of removing trailing blanks from the resulting array is disabled:

".".split("\\.", -1) // returns an array of two blanks, ie ["", ""]

ie, when filename is just a dot ".", calling filename.split("\\.", -1)[0] will return a blank, but calling filename.split("\\.")[0] will throw an ArrayIndexOutOfBoundsException.

git reset and git clean can be overkill in some situations (and be a huge waste of time).

If you simply have a message like "The following untracked files would be overwritten..." and you want the remote/origin/upstream to overwrite those conflicting untracked files, then git checkout -f <branch> is the best option.

If you're like me, your other option was to clean and perform a --hard reset then recompile your project.
