You have to include sort function which is in algorithm header file which is a standard template library in c++.

Usage: std::sort(str.begin(), str.end());

#include <iostream>
#include <algorithm>  // this header is required for std::sort to work
int main()
{
    std::string s = "dacb";
    std::sort(s.begin(), s.end());
    std::cout << s << std::endl;

    return 0;
}

OUTPUT:

Javax used to be only for extensions. Yet later sun added it to the java libary forgetting to remove the x. Developers started making code with javax. Yet later on in time suns decided to change it to java. Developers didn't like the idea because they're code would be ruined... so javax was kept.

My understanding of SQLiteDatabase APIs is that in case you have a multi threaded application, you cannot afford to have more than a 1 SQLiteDatabase object pointing to a single database.

The object definitely can be created but the inserts/updates fail if different threads/processes (too) start using different SQLiteDatabase objects (like how we use in JDBC Connection).

The only solution here is to stick with 1 SQLiteDatabase objects and whenever a startTransaction() is used in more than 1 thread, Android manages the locking across different threads and allows only 1 thread at a time to have exclusive update access.

Also you can do "Reads" from the database and use the same SQLiteDatabase object in a different thread (while another thread writes) and there would never be database corruption i.e "read thread" wouldn't read the data from the database till the "write thread" commits the data although both use the same SQLiteDatabase object.

This is different from how connection object is in JDBC where if you pass around (use the same) the connection object between read and write threads then we would likely be printing uncommitted data too.

In my enterprise application, I try to use conditional checks so that the UI Thread never have to wait, while the BG thread holds the SQLiteDatabase object (exclusively). I try to predict UI Actions and defer BG thread from running for 'x' seconds. Also one can maintain PriorityQueue to manage handing out SQLiteDatabase Connection objects so that the UI Thread gets it first.

Let us see the difference between the two HTTP authentication using Wireshark (Tool to analyse packets sent or received) .

1. Http Basic Authentication

As soon as the client types in the correct username:password,as requested by the Web-server, the Web-Server checks in the Database if the credentials are correct and gives the access to the resource .

Here is how the packets are sent and received :

In the first packet the Client fill the credentials using the POST method at the resource - lab/webapp/basicauth .In return the server replies back with http response code 200 ok ,i.e, the username:password were correct .

Now , In the Authorization header it shows that it is Basic Authorization followed by some random string .This String is the encoded (Base64) version of the credentials admin:aadd (including colon ) .

2 . Http Digest Authentication(rfc 2069)

So far we have seen that the Basic Authentication sends username:password in plaintext over the network .But the Digest Auth sends a HASH of the Password using Hash algorithm.

Here are packets showing the requests made by the client and response from the server .

As soon as the client types the credentials requested by the server , the Password is converted to a response using an algorithm and then is sent to the server , If the server Database has same response as given by the client the server gives the access to the resource , otherwise a 401 error .

In the above Authorization , the response string is calculated using the values of Username,Realm,Password,http-method,URI and Nonce as shown in the image :

(colons are included)

Hence , we can see that the Digest Authentication is more Secure as it involve Hashing (MD5 encryption) , So the packet sniffer tools cannot sniff the Password although in Basic Auth the exact Password was shown on Wireshark.

In vb.net, if you are using a linked server than check your connection string. Integrated Security=true; doesn't work in all SQL providers, it throws an exception when used with the OleDb provider. So basically Integrated Security=SSPI; is preferred since works with both SQLClient & OleDB provide. If you still hit with error, remove the syntax completely.

This can be one of several solutions:

var text = "http://example.com";

JSON.stringify(text).replace('\"', '\"\'').replace(/.$/, '\'"')

brew reinstall php56-mcrypt --build-from-source

Do this—pass the --build-from-source flag—for each module which needs to be compiled with the same version.

It may also require PHP options depending on your plugins. If so, brew reinstall php56 --with-thread-safety

To see all of the options for php[version] run brew options php56 (replacing 56 with your version)

My workaround is to get the current title of the actionbar in the Fragment before setting it to the new title. This way, once the Fragment is popped, I can change back to that title.

@Override
public void onResume() {
    super.onResume();
    // Get/Backup current title
    mTitle = ((ActionBarActivity) getActivity()).getSupportActionBar()
            .getTitle();
    // Set new title
    ((ActionBarActivity) getActivity()).getSupportActionBar()
        .setTitle(R.string.this_fragment_title);
}

@Override
public void onDestroy() {
    // Set title back
    ((ActionBarActivity) getActivity()).getSupportActionBar()
        .setTitle(mTitle);

    super.onDestroy();
}

If your detached HEAD is a fast forward of master and you just want the commits upstream, you can

git push origin HEAD:master

to push directly, or

git checkout master && git merge [ref of HEAD]

will merge it back into your local master.

try parsing a default value which can be returned by max if length of v none

max(v, default=0)

The trick is a second .box-inner inside, which is larger in width than the original .box, and the box-shadow is applied to that.

Then, added more padding to the .text to make up for the added width.

This is how the logic looks:

And here's how it's done in CSS:

Use max width for .inner-box to not cause .box to get wider, and overflow to make sure the remaining is clipped:

.box {
    max-width: 100% !important;
    overflow: hidden;
}

110% is wider than the parent which is 100% in a child's context (should be the same when the parent .box has a fixed width, for example). Negative margins make up for the width and cause the element to be centered (instead of only the right part hiding):

.box-inner {
    width: 110%;
    margin-left:-5%;
    margin-right: -5%;
    -webkit-box-shadow: inset 0px 5px 10px 1px #000000;
    box-shadow: inset 0px 5px 10px 1px #000000;
}

And add some padding on the X axis to make up for the wider .inner-box:

.text {
    padding: 20px 40px;
}

Here's a working Fiddle.

If you inspect the Fiddle, you'll see:

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

• Yes, although it can be tricky to get debugging working, especially if trying to debug SQL on a remote SQL server from your own development machine.
• In the first instance I'd recommend getting this working by debugging directly on the server first, if possible.
• Log to the SQL server using an account that has sysadmin rights, or ask your DBA to to do this.
• Then, for your own Windows account, create a 'login' in SQL Server, if it isn't already there:

• Right-click the account > properties - ensure that the login is a member of the 'sysadmin' role:

• (also ensure that the account is 'owner' of any databases that you want to debug scripts (e.g. stored procs) for:

• Then, login directly onto the SQL server using your Windows account.
• Login to SQL server using Windows Authentication (using the account you've just used to log into the server)
• Now 'Debug' the query in SQL management studio, setting breakpoints as necessary. You can step into stored procs using F11:

• Here's a useful guide to debugging:

http://blogs.msdn.com/b/billramo/archive/2009/04/11/transact-sql-debugger-for-sql-server-2008-part-1.aspx

• If you need to remotely debug, then once you've got this part working, you can try setting up remote debugging:

If you want this type of code to run in IE11 (which does not support much of ES6 at all), then you need to get a 3rd party promise library (like Bluebird), include that library and change your coding to use ES5 coding structures (no arrow functions, no let, etc...) so you can live within the limits of what older browsers support.

Or, you can use a transpiler (like Babel) to convert your ES6 code to ES5 code that will work in older browsers.

Here's a version of your code written in ES5 syntax with the Bluebird promise library:

<script src="https://cdnjs.cloudflare.com/ajax/libs/bluebird/3.3.4/bluebird.min.js"></script>

<script>

'use strict';

var promise = new Promise(function(resolve) {
    setTimeout(function() {
        resolve("result");
    }, 1000);
});

promise.then(function(result) {
    alert("Fulfilled: " + result);
}, function(error) {
    alert("Rejected: " + error);
});

</script>

In JavaScript, the type of key/value store you are attempting to use is an object literal, rather than an array. You are mistakenly creating a composite array object, which happens to have other properties based on the key names you provided, but the array portion contains no elements.

Instead, declare valueToPush as an object and push that onto cookie_value_add:

// Create valueToPush as an object {} rather than an array []
var valueToPush = {};

// Add the properties to your object
// Note, you could also use the valueToPush["productID"] syntax you had
// above, but this is a more object-like syntax
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;

cookie_value_add.push(valueToPush);

// View the structure of cookie_value_add
console.dir(cookie_value_add);

You can use cin.get(); or cin.ignore(); just before your return statement to avoid the console window from closing.

In case if anyone wants to grab only the Time from a ISO Date, following will be helpful. I was searching for that and I couldn't find a question for it. So in case some one sees will be helpful.

let isoDate = '2020-09-28T15:27:15+05:30';
let result = isoDate.match(/\d\d:\d\d/);
console.log(result[0]);

The output will be the only the time from isoDate which is,

15:27

You need to go to user accounts and enable Guest Account, its default disabled. Once you do this, you share any folder and add the guest account to the list of users who can accesss that specific folder, this also includes to Turn off password Protected Sharing in 'Advanced Sharing Settings'

The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.

Using imgscalr – Java Image Scaling Library:

Here is a method, which does not use jQuery. I used it to create a bookmarklet, which checks the current page on w3-html-validator.

var f = document.createElement('form');
f.action='http://validator.w3.org/check';
f.method='POST';
f.target='_blank';

var i=document.createElement('input');
i.type='hidden';
i.name='fragment';
i.value='<!DOCTYPE html>'+document.documentElement.outerHTML;
f.appendChild(i);

document.body.appendChild(f);
f.submit();

The web.xml file should be listed right below the last line in your screenshot and resides in WebContent/WEB-INF. If it is missing you might have missed to check the "Generate web.xml deployment descriptor" option on the third page of the Dynamic web project wizard.

the perfect solution is to Using UICollectionViewDelegateFlowLayout but you can easily so calculate the cell width and divided on the wanted number of columns you want

the tricky is to make the width with no fraction

(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath

{
 CGFloat screenWidth = self.view.frame.size.width;
   CGFloat marginWidth = (screenWidth - collectionView.frame.size.width);


   CGFloat cellWith = (collectionView.frame.size.width - marginWidth )/3;
   cellWith= floorf(cellWith);




  CGSize retval = CGSizeMake(cellWith,cellWith);


  return retval;}

Based on solution You've already found How to apply CSS to iframe?:

var cssLink = document.createElement("link") 
cssLink.href = "file://path/to/style.css"; 
cssLink .rel = "stylesheet"; 
cssLink .type = "text/css"; 
frames['iframe'].document.body.appendChild(cssLink);

or more jqueryish (from Append a stylesheet to an iframe with jQuery):

var $head = $("iframe").contents().find("head");                
$head.append($("<link/>", 
    { rel: "stylesheet", href: "file://path/to/style.css", type: "text/css" }));

as for security issues: Disabling same-origin policy in Safari

Run this command:

select @@version

If you want a list of lists:

>>> [list(t) for t in zip(*l)]
[[1, 3, 8], [2, 4, 9]]

If a list of tuples is OK:

>>> zip(*l)
[(1, 3, 8), (2, 4, 9)]

I have written a class based on "Chandra Nakka" answer.

Answering the 'op' question with this class you can call

$country = (new \Geo())->get('country'); // United Kingdom

And the other properties available are:

$geo = new \Geo('185.35.50.4');
var_dump($geo->get('*')); // allias all / location
var_dump($geo->get('country'));
var_dump($geo->get('countrycode'));
var_dump($geo->get('state')); // allias region
var_dump($geo->get('city')); 
var_dump($geo->get('address')); 
var_dump($geo->get('continent')); 
var_dump($geo->get('continentcode'));   
var_dump($geo->get('request'));
var_dump($geo->get('latitude'));
var_dump($geo->get('longitude'));
var_dump($geo->get('accuracy'));
var_dump($geo->get('timezonde'));
var_dump($geo->get('currencyCode'));
var_dump($geo->get('currencySymbol'));
var_dump($geo->get('currencySymbolUTF8'));

You might be able to do this with AutoGenerateColumns and a DataTemplate. I'm not positive if it would work without a lot of work, you would have to play around with it. Honestly if you have a working solution already I wouldn't make the change just yet unless there's a big reason. The DataGrid control is getting very good but it still needs some work (and I have a lot of learning left to do) to be able to do dynamic tasks like this easily.

Adding to cchana's answer. The method "length-6" fails on non-latin values in enum.

For example (the values are in Cyrillic, table is UTF8 - utf8_general_ci. In the examples I use the variable for simplicity: selecting from schema gives the same):

set @a:="enum('? ??????','?? ????????','???????')";
select substring(@a,6,length(@a)-6);
+-------------------------------------------------------------+
| substring(@a,6,length(@a)-6)                                |
+-------------------------------------------------------------+
| '? ??????','?? ????????','???????')                         |
+-------------------------------------------------------------+

Note the closing parenthesis?

select right(@a,1);
+-------------+
| right(@a,1) |
+-------------+
| )           |
+-------------+

Well, let's try remove one more character:

select substring(@a,6,length(@a)-7);
+-------------------------------------------------------------+
| substring(@a,6,length(@a)-7)                                |
+-------------------------------------------------------------+
| '? ??????','?? ????????','???????')                         |
+-------------------------------------------------------------+

No luck! The parenthesis stays in place.

Checking (mid() function works in way similar to substring(), and both shows the same results):

select mid(@a,6,length(@a)/2);
+---------------------------------------------------------+
| mid(@a,6,length(@a)/2)                                  |
+---------------------------------------------------------+
| '? ??????','?? ????????','??????                        |
+---------------------------------------------------------+

See: the string lost only three rightmost characters. But should we replace Cyrillic with Latin, and all works just perfectly:

set @b:="enum('in use','for removal','trashed')";
select (substring(@b,6,length(@b)-6));
+----------------------------------+
| (substring(@b,6,length(@b)-6))   |
+----------------------------------+
| 'in use','for removal','trashed' |
+----------------------------------+

JFYI

Edit 20210221: the solution for non-Latin characters is CHAR_LENGTH() instead of "simple" LENGTH()

Selector Context By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function. For example, to do a search within an event handler, the search can be restricted like so:

$( "div.foo" ).click(function() { 
   $( "span", this ).addClass( "bar" );
});

When the search for the span selector is restricted to the context of this, only spans within the clicked element will get the additional class.

So for your example I would suggest something like:

$("div", ".container").each(function(){
     //do whatever
 });

Just in case you want to handle the behaviour of the back button (at the bottom of the phone) and the home button (the one to the left of the action bar), this custom activity I'm using in my project may help you.

import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;

/**
 * Activity where the home action bar button behaves like back by default
 */
public class BackActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setupHomeButton();
    }

    private void setupHomeButton() {
        final ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.setDisplayHomeAsUpEnabled(true);
            actionBar.setHomeButtonEnabled(true);
        }
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                onMenuHomePressed();
                return true;
        }
        return super.onOptionsItemSelected(item);
    }

    protected void onMenuHomePressed() {
        onBackPressed();
    }
}

Example of use in your activity:

public class SomeActivity extends BackActivity {

    // ....

    @Override
    public void onBackPressed()
    {
        // Example of logic
        if ( yourConditionToOverride ) {
            // ... do your logic ...
        } else {
            super.onBackPressed();
        }
    }    
}

This works from Java 5 to 7:

public int getTheNumber(Integer... factors) {
    ArrayList<Integer> f = new ArrayList<Integer>(Arrays.asList(factors));
    Collections.sort(f);
    return f.get(0)*f.get(f.size()-1);
}

In Java 4 there is no vararg... :-)

Try with this one:

$(document).ready(function(){
  $('a').click(function(e){
     e.preventDefault();
     $("#content").load($(this).attr('href'));
  });
});

and make sure to call this library first:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js">
</script>

You can create a function like:

def similar(w1, w2):
    w1 = w1 + ' ' * (len(w2) - len(w1))
    w2 = w2 + ' ' * (len(w1) - len(w2))
    return sum(1 if i == j else 0 for i, j in zip(w1, w2)) / float(len(w1))

struct node{
    int position;
    char name[30];
    struct node * next;
};

void free_list(node * list){
    node* next_node;

    printf("\n\n Freeing List: \n");
    while(list != NULL)
    {
        next_node = list->next;
        printf("clear mem for: %s",list->name);
        free(list);
        list = next_node;
        printf("->");
    }
}

I suspect that the problem is that the path is incorrect. Try this:

UserInput.prompt("Enter name of file to delete");
String name = UserInput.readString();
File file = new File("\\Files\\" + name + ".txt");
if (file.exists()) {
    file.delete();
} else {
    System.err.println(
        "I cannot find '" + file + "' ('" + file.getAbsolutePath() + "')");
}

Since START is the only way to execute something in the background from a CMD script, I would recommend you keep using it. Instead of the /B modifier, try /MIN so the newly created window won't bother you. Also, you can set the priority to something lower with /LOW or /BELOWNORMAL, which should improve your system responsiveness.

If it was me I would introduce new CSS class and use along with unmodified bootstrap row class.

HTML

<div class="row extra-bottom-padding" id="a">
   <img>...</img>
<div>
<div class="row" id="b">
   <button>..</button>
<div>

CSS

.row.extra-bottom-padding{
   margin-bottom: 20px;
}

Use the git commit command without any flags. The configured editor will open (Vim in this case):

To start typing press the INSERT key on your keyboard, then in insert mode create a better commit with description how do you want. For example:

Once you have written all that you need, to returns to git, first you should exit insert mode, for that press ESC. Now close the Vim editor with save changes by typing on the keyboard :wq (w - write, q - quit):

and press ENTER.

On GitHub this commit will looks like this:

As a commit editor you can use VS Code:

git config --global core.editor "code --wait"

From VS Code docs website: VS Code as Git editor

Gif demonstration:

taskkill /F /IM notepad.exe this is the best way to kill the task from task manager.

you can also try the more generic version which gives you the ith element

enumerable.ElementAtOrDefault(i));

hope it helps

I would use matplotlib's pcolor/pcolormesh function since it allows nonuniform spacing of the data.

Example taken from matplotlib:

import matplotlib.pyplot as plt
import numpy as np

# generate 2 2d grids for the x & y bounds
y, x = np.meshgrid(np.linspace(-3, 3, 100), np.linspace(-3, 3, 100))

z = (1 - x / 2. + x ** 5 + y ** 3) * np.exp(-x ** 2 - y ** 2)
# x and y are bounds, so z should be the value *inside* those bounds.
# Therefore, remove the last value from the z array.
z = z[:-1, :-1]
z_min, z_max = -np.abs(z).max(), np.abs(z).max()

fig, ax = plt.subplots()

c = ax.pcolormesh(x, y, z, cmap='RdBu', vmin=z_min, vmax=z_max)
ax.set_title('pcolormesh')
# set the limits of the plot to the limits of the data
ax.axis([x.min(), x.max(), y.min(), y.max()])
fig.colorbar(c, ax=ax)

plt.show()

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

Hive tables may not necessarily be stored in a warehouse (since you can create tables located anywhere on the HDFS).

You should use DESCRIBE FORMATTED <table_name> command.

hive -S -e "describe formatted <table_name> ;" | grep 'Location' | awk '{ print $NF }'

Please note that partitions may be stored in different places and to get the location of the alpha=foo/beta=bar partition you'd have to add partition(alpha='foo',beta='bar') after <table_name>.

I was facing the same issue as below.

The problem I made was, I was running the command npm build run instead of running npm run build.

My suggestion would be to use RestSharp. You can make calls to REST services and have them cast into POCO objects with very little boilerplate code to actually have to parse through the response. This will not solve your particular error, but it answers your overall question of how to make calls to REST services. Having to change your code to use it should pay off in the ease of use and robustness moving forward. That is just my two cents though.

Example:

namespace RestSharpThingy

    using System;

In C++, references can't be null. If you want to optionally return null if nothing is found, you need to return a pointer, not a reference:

Attr *getAttribute(const string& attribute_name) const {
   //search collection
   //if found at i
        return &attributes[i];
   //if not found
        return nullptr;
}

Otherwise, if you insist on returning by reference, then you should throw an exception if the attribute isn't found.

(By the way, I'm a little worried about your method being const and returning a non-const attribute. For philosophical reasons, I'd suggest returning const Attr *. If you also may want to modify this attribute, you can overload with a non-const method returning a non-const attribute as well.)

Well, as you are just looking to match the position of a character , regex is possibly overkill.

I presume all you want is, instead of "find first of these this character" , just find first of these characters.

This of course is the simple answer, but does what your question sets out to do, albeit without the regex part ( because you didn't clarify why specifically it had to be a regex )

function mIndexOf( str , chars, offset )
{
   var first  = -1; 
   for( var i = 0; i < chars.length;  i++ )
   {
      var p = str.indexOf( chars[i] , offset ); 
      if( p < first || first === -1 )
      {
           first = p;
      }
   }
   return first; 
}
String.prototype.mIndexOf = function( chars, offset )
{
   return mIndexOf( this, chars, offset ); # I'm really averse to monkey patching.  
};
mIndexOf( "hello world", ['a','o','w'], 0 );
>> 4 
mIndexOf( "hello world", ['a'], 0 );
>> -1 
mIndexOf( "hello world", ['a','o','w'], 4 );
>> 4
mIndexOf( "hello world", ['a','o','w'], 5 );
>> 6
mIndexOf( "hello world", ['a','o','w'], 7 );
>> -1 
mIndexOf( "hello world", ['a','o','w','d'], 7 );
>> 10
mIndexOf( "hello world", ['a','o','w','d'], 10 );
>> 10
mIndexOf( "hello world", ['a','o','w','d'], 11 );

PLplot is a cross-platform software package for creating scientific plots. They aren't very pretty (eye catching), but they look good enough. Have a look at some examples (both source code and pictures).

The PLplot core library can be used to create standard x-y plots, semi-log plots, log-log plots, contour plots, 3D surface plots, mesh plots, bar charts and pie charts. It runs on Windows (2000, XP and Vista), Linux, Mac OS X, and other Unices.

I use:

> echo Aa | tr -d '\n' | xxd -p
4161

> echo 414161 | tr -d '\n' | xxd -r -p
AAa

The tr -d '\n' will trim any possible newlines in your input

getPathInfo() gives the extra path information after the URI, used to access your Servlet, where as getRequestURI() gives the complete URI.

I would have thought they would be different, given a Servlet must be configured with its own URI pattern in the first place; I don't think I've ever served a Servlet from root (/).

For example if Servlet 'Foo' is mapped to URI '/foo' then I would have thought the URI:

/foo/path/to/resource

Would result in:

RequestURI = /foo/path/to/resource

and

PathInfo = /path/to/resource

Hello guys I am stucked with this. I've a Document Profile who has a reference to User,and I've tried to list the profiles where user ref is not null (because I already filtered by rol during the population), but after googleing a few hours I cannot figure out how to get this. I have this query:

const profiles = await Profile.find({ user: {$exists: true,  $ne: null }})
                            .select("-gallery")
                            .sort( {_id: -1} )
                            .skip( skip )
                            .limit(10)
                            .select(exclude)
                            .populate({
                                path: 'user',
                                match: { role: {$eq: customer}},
                                select: '-password -verified -_id -__v'
                              })

                            .exec();

And I get this result, how can I remove from the results the user:null colletions? . I meant, I dont want to get the profile when user is null (the role does not match).

The following will work for KornShell(ksh) where the process substitution is not available,

# create a combined(stdin and stdout) collector
exec 3 <> combined.log

# stream stderr instead of stdout to tee, while draining all stdout to the collector
./aaa.sh 2>&1 1>&3 | tee -a stderr.log 1>&3

# cleanup collector
exec 3>&-

The real trick here, is the sequence of the 2>&1 1>&3 which in our case redirects the stderr to stdout and redirects the stdout to descriptor 3. At this point the stderr and stdout are not combined yet.

In effect, the stderr(as stdin) is passed to tee where it logs to stderr.log and also redirects to descriptor 3.

And descriptor 3 is logging it to combined.log all the time. So the combined.log contains both stdout and stderr.

I think what you want is:

select {
  direction: rtl;
}

As the other answers say, the best way is to do

npm list -g

However, if you have a large number of npm packages installed, the output of this command could be very long and a big pain to scroll up (sometimes it's not even possible to scroll that far back).

In this case, pipe the output to the more program, like this

npm list -g | more

From the documentation:

The load factor is a measure of how full the hash table is allowed to get before its capacity is automatically increased

It really depends on your particular requirements, there's no "rule of thumb" for specifying an initial load factor.

One quick comment to user306253's answer: caution with this, when you try to load something in the UIWebView yourself (i.e. even from the code), this method will prevent it to happened.

What you can do to prevent this (thanks Wade) is:

if (inType == UIWebViewNavigationTypeLinkClicked) {
    [[UIApplication sharedApplication] openURL:[inRequest URL]];
    return NO;
}

return YES;

You might also want to handle the UIWebViewNavigationTypeFormSubmitted and UIWebViewNavigationTypeFormResubmitted types.

The warning message is because your "Type" variable was made a factor and "lunch" was not a defined level. Use the stringsAsFactors = FALSE flag when making your data frame to force "Type" to be a character.

> fixed <- data.frame("Type" = character(3), "Amount" = numeric(3))
> str(fixed)
'data.frame':   3 obs. of  2 variables:
 $ Type  : Factor w/ 1 level "": NA 1 1
 $ Amount: chr  "100" "0" "0"
> 
> fixed <- data.frame("Type" = character(3), "Amount" = numeric(3),stringsAsFactors=FALSE)
> fixed[1, ] <- c("lunch", 100)

 $ Type  : chr  "lunch" "" ""
 $ Amount: chr  "100" "0" "0"

The type of the elements of an std::map (which is also the type of an expression obtained by dereferencing an iterator of that map) whose key is K and value is V is std::pair<const K, V> - the key is const to prevent you from interfering with the internal sorting of map values.

std::pair<> has two members named first and second (see here), with quite an intuitive meaning. Thus, given an iterator i to a certain map, the expression:

i->first

Which is equivalent to:

(*i).first

Refers to the first (const) element of the pair object pointed to by the iterator - i.e. it refers to a key in the map. Instead, the expression:

i->second

Which is equivalent to:

(*i).second

Refers to the second element of the pair - i.e. to the corresponding value in the map.

I suggest not to rely on stack elements. If someone use your code within different contexts (python interpreter for instance) your stack will change and break your index ([0][3]).

I suggest you something like that:

class MyClass:

    def __init__(self):
        self.function_name = None

    def _Handler(self, **kwargs):
        print('Calling function {} with parameters {}'.format(self.function_name, kwargs))
        self.function_name = None

    def __getattr__(self, attr):
        self.function_name = attr
        return self._Handler


mc = MyClass()
mc.test(FirstParam='my', SecondParam='test')
mc.foobar(OtherParam='foobar')

The documentation is your friend, NSString supports a call substringWithRange that can shorten the string that you have an return the shortened String. You cannot modify an instance of NSString it is immutable. If you have an NSMutableString is has a method called deleteCharactersInRange that can modify the string in place

...
NSRange r;
r.location = 0;
r.size = [mutable length]-1;
NSString* shorted = [stringValue substringWithRange:r];
...

Is this worth mentioning?

var item = new Stack(arr).Pop();

Because Label1.Text is holding Label which can't be parsed into integer, you need to convert the associated textbox's text to integer

imageWidth = 1 * Convert.ToInt32(TextBox2.Text);

Based on this viedo: VB.net-Auto generate row number to datagridview in windows application-winforms, you can set the DataSource and this code puts the rows numbers, works like a charm.

private void DataGrid_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    // Add row number
    (sender as DataGridView).Rows[e.RowIndex].HeaderCell.Value = (e.RowIndex+1).ToString();
}

You are correct that storing the password in a plain-text field is a horrible idea. However, as far as location goes, for most of the cases you're going to encounter (and I honestly can't think of any counter-examples) storing the representation of a password in the database is the proper thing to do. By representation I mean that you want to hash the password using a salt (which should be different for every user) and a secure 1-way algorithm and store that, throwing away the original password. Then, when you want to verify a password, you hash the value (using the same hashing algorithm and salt) and compare it to the hashed value in the database.

So, while it is a good thing you are thinking about this and it is a good question, this is actually a duplicate of these questions (at least):

• How to best store user information and user login and password
• Best practices for storing database passwords
• Salting Your Password: Best Practices?
• Is it ever ok to store password in plain text in a php variable or php constant?

To clarify a bit further on the salting bit, the danger with simply hashing a password and storing that is that if a trespasser gets a hold of your database, they can still use what are known as rainbow tables to be able to "decrypt" the password (at least those that show up in the rainbow table). To get around this, developers add a salt to passwords which, when properly done, makes rainbow attacks simply infeasible to do. Do note that a common misconception is to simply add the same unique and long string to all passwords; while this is not horrible, it is best to add unique salts to every password. Read this for more.

WWW-Authenticate header

You may also get this if the server is sending a 401 response code but not setting the WWW-Authenticate header correctly - I should know, I've just fixed that in out own code because VB apps weren't popping up the authentication prompt.

My favorite "swiss knife" Beyond Compare from http://www.scootersoftware.com/

You can mix git blame and git log commands to retrieve the summary of each commit in the git blame command and append them. Something like the following bash + awk script. It appends the commit summary as code comment inline.

git blame FILE_NAME | awk -F" " \
'{
   commit = substr($0, 0, 8);
   if (!a[commit]) {
     query = "git log --oneline -n 1 " commit " --";
     (query | getline a[commit]);
   }
   print $0 "  // " substr(a[commit], 9);
 }'

In one line:

git blame FILE_NAME | awk -F" " '{ commit = substr($0, 0, 8); if (!a[commit]) { query = "git log --oneline -n 1 " commit " --"; (query | getline a[commit]); } print $0 "  // " substr(a[commit], 9); }'

You need to import FormsModule in your @NgModule Decorator, @NgModule is present in your moduleName.module.ts file.

import { FormsModule } from '@angular/forms';
@NgModule({
   imports: [
      BrowserModule,
      FormsModule
   ],
   declarations: [ AppComponent ],
   bootstrap: [ AppComponent ]
 })

For anyone else that may encounter this problem and it is not solved by either of the options above, this is what worked for me.

1. Click on the website in IIS
2. Double Click on Authentication under IIS
3. Enable Anonymous Authentication

I had disabled this because we were using our own Auth, but that lead to this same problem and the accepted answer did not help in any way.

Qt has a method for copying files:

#include <QFile>
QFile::copy("originalFile.example","copiedFile.example");

Note that to use this you have to install Qt (instructions here) and include it in your project (if you're using Windows and you're not an administrator, you can download Qt here instead). Also see this answer.

I think you can use [UIScreen mainScreen].bounds.size.height and calculate step for your objects. when you calculate step you can set coordinates for two resolutions.

Or you can get height like above and if(iphone5) then... else if(iphone4) then... else if(ipad). Something like this.

If you use storyboards then you have to create new for new iPhone i think.

could it be that you forgot to load it in the document ready function?

$(document).ready(function () {

    //your jQuery function
});

//here threshold,buyRange,targetPercentage are three keys on that i have sorted my arraylist 
final Comparator<BasicDBObject> 

    sortOrder = new Comparator<BasicDBObject>() {
                    public int compare(BasicDBObject e1, BasicDBObject e2) {
                        int threshold = new Double(e1.getDouble("threshold"))
                        .compareTo(new Double(e2.getDouble("threshold")));
                        if (threshold != 0)
                            return threshold;

                        int buyRange = new Double(e1.getDouble("buyRange"))
                        .compareTo(new Double(e2.getDouble("buyRange")));
                        if (buyRange != 0)
                            return buyRange;

                        return (new Double(e1.getDouble("targetPercentage")) < new Double(
                                e2.getDouble("targetPercentage")) ? -1 : (new Double(
                                        e1.getDouble("targetPercentage")) == new Double(
                                                e2.getDouble("targetPercentage")) ? 0 : 1));
                    }
                };
                Collections.sort(objectList, sortOrder);

id selector can be used to more elements. here is the example:

css:

#t_color{
    color: red;
}
#f_style{
    font-family: arial;
    font-size: 20px;
}

html:

<p id="t_color"> test only </p>
<div id="t_color">the box text</div>

I tested on internet explorer (ver. 11.0) and Chrome (ver.47.0). it works on both of them.

The "unique" only means one element can not have more than one id attributes like class selector. Neither

<p id="t_color f_style">...</p>

nor

<p id="t_color" id="f_style">...</p>

Setting net.ipv6.conf.all.forwarding=1 will fix the issue.

This can be done on a live system using sudo sysctl -w net.ipv6.conf.all.forwarding=1

Use this method:

public static int RunProcessAsAdmin(string exeName, string parameters)
    {
        try {
            System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
            startInfo.UseShellExecute = true;
            startInfo.WorkingDirectory = CurrentDirectory;
            startInfo.FileName = Path.Combine(CurrentDirectory, exeName);
            startInfo.Verb = "runas";
            //MLHIDE
            startInfo.Arguments = parameters;
            startInfo.ErrorDialog = true;

            Process process = System.Diagnostics.Process.Start(startInfo);
            process.WaitForExit();
            return process.ExitCode;
        } catch (Win32Exception ex) {
            WriteLog(ex);
            switch (ex.NativeErrorCode) {
                case 1223:
                    return ex.NativeErrorCode;
                default:
                    return ErrorReturnInteger;
            }

        } catch (Exception ex) {
            WriteLog(ex);
            return ErrorReturnInteger;
        }
    }

Hope it helps.

From JLS http://docs.oracle.com/javase/specs/jls/se5.0/html/arrays.html#10.2

Here are examples of declarations of array variables that do not create arrays:

int[ ] ai;          // array of int
short[ ][ ] as;         // array of array of short
Object[ ]   ao,     // array of Object
        otherAo;    // array of Object
Collection<?>[ ] ca;        // array of Collection of unknown type
short       s,      // scalar short 
        aas[ ][ ];  // array of array of short

Here are some examples of declarations of array variables that create array objects:

Exception ae[ ] = new Exception[3]; 
Object aao[ ][ ] = new Exception[2][3];
int[ ] factorial = { 1, 1, 2, 6, 24, 120, 720, 5040 };
char ac[ ] = { 'n', 'o', 't', ' ', 'a', ' ',
                 'S', 't', 'r', 'i', 'n', 'g' }; 
String[ ] aas = { "array", "of", "String", };

The [ ] may appear as part of the type at the beginning of the declaration, or as part of the declarator for a particular variable, or both, as in this example:

byte[ ] rowvector, colvector, matrix[ ];

This declaration is equivalent to:

byte rowvector[ ], colvector[ ], matrix[ ][ ];

FQDN means the resolved name over DNS. It should be like "server-name.search-domain".

The warning you get just provides a notice that httpd can not find a FQDN, so it might not work right to handle a name-based virtual host. So make sure the expected FQDN is registered in your DNS server, or manually add the entry in /etc/hosts which is prior to hitting DNS.

Head First SQL is a great introduction.

This might be an alternative solution. Paste the following code into the new module:

Public Function ModDate()
ModDate = 
Format(FileDateTime(ThisWorkbook.FullName), "m/d/yy h:n ampm") 
End Function

Before saving your module, make sure to save your Excel file as Excel Macro-Enabled Workbook.

Paste the following code into the cell where you want to display the last modification time:

=ModDate()

I'd also like to recommend an alternative to Excel allowing you to add creation and last modification time easily. Feel free to check on RowShare and this article I wrote: https://www.rowshare.com/blog/en/2018/01/10/Displaying-Last-Modification-Time-in-Excel

GetType() exists on every single framework type, because it is defined on the base object type. So, regardless of the type itself, you can use it to return the underlying Type

So, all you need to do is:

u.GetType() == t

I think you're talking about the logical meaning of both operators, here you have a table-resume:

boolean a, b;

Operation     Meaning                       Note
---------     -------                       ----
   a && b     logical AND                    short-circuiting
   a || b     logical OR                     short-circuiting
   a &  b     boolean logical AND            not short-circuiting
   a |  b     boolean logical OR             not short-circuiting
   a ^  b     boolean logical exclusive OR
  !a          logical NOT

short-circuiting        (x != 0) && (1/x > 1)   SAFE
not short-circuiting    (x != 0) &  (1/x > 1)   NOT SAFE

Short-circuit evaluation, minimal evaluation, or McCarthy evaluation (after John McCarthy) is the semantics of some Boolean operators in some programming languages in which the second argument is executed or evaluated only if the first argument does not suffice to determine the value of the expression: when the first argument of the AND function evaluates to false, the overall value must be false; and when the first argument of the OR function evaluates to true, the overall value must be true.

Not Safe means the operator always examines every condition in the clause, so in the examples above, 1/x may be evaluated when the x is, in fact, a 0 value, raising an exception.

Kotlin supports operators overloading

In Kotlin you can easily compare dates with compare operators. Because Kotlin already support operators overloading. So to compare date objects :

firstDate: Date = // your first date
secondDate: Date = // your second date

if(firstDate < secondDate){
// fist date is before second date
}

and if you're using calendar objects, you can easily compare like this:

if(cal1.time < cal2.time){
// cal1 date is before cal2 date
}

Select SUM(CASE When CPayment='Cash' Then CAmount Else 0 End ) as CashPaymentAmount,
       SUM(CASE When CPayment='Check' Then CAmount Else 0 End ) as CheckPaymentAmount
from TableOrderPayment
Where ( CPayment='Cash' Or CPayment='Check' ) AND CDate<=SYSDATETIME() and CStatus='Active';

You've added a button to your DataGridView and you want to run some code when it's clicked.
Easy peasy - just follow these steps:

Don'ts:

First, here's what NOT to do:

I would avoid the suggestions in some of the other answers here and even provided by the documentation at MSDN to hardcode the column index or column name in order to determine if a button was clicked. The click event registers for the entire grid, so somehow you need to determine that a button was clicked, but you should not do so by assuming that your button lives in a particular column name or index... there's an easier way...

Also, be careful which event you want to handle. Again, the documentation and many examples get this wrong. Most examples handle the CellClick event which will fire:

when any part of a cell is clicked.

...but will also fire whenever the row header is clicked. This necessitates adding extra code simply to determine if the e.RowIndex value is less than 0

Instead handle the CellContentClick which only occurs:

when the content within a cell is clicked

For whatever reason, the column header is also considered 'content' within a cell, so we'll still have to check for that below.

Dos:

So here's what you should do:

First, cast the sender to type DataGridView to expose it's internal properties at design time. You can modify the type on the parameter, but that can sometimes make adding or removing handlers tricky.

Next, to see if a button was clicked, just check to make sure that the column raising the event is of type DataGridViewButtonColumn. Because we already cast the sender to type DataGridView, we can get the Columns collection and select the current column using e.ColumnIndex. Then check if that object is of type DataGridViewButtonColumn.

Of course, if you need to distinguish between multiple buttons per grid, you can then select based on the column name or index, but that shouldn't be your first check. Always make sure a button was clicked first and then handle anything else appropriately. In most cases where you only have a single button per grid, you can jump right off to the races.

Putting it all together:

C#:

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    var senderGrid = (DataGridView)sender;

    if (senderGrid.Columns[e.ColumnIndex] is DataGridViewButtonColumn &&
        e.RowIndex >= 0)
    {
        //TODO - Button Clicked - Execute Code Here
    }
}

VB:

Private Sub DataGridView1_CellContentClick(sender As System.Object, e As DataGridViewCellEventArgs) _
                                           Handles DataGridView1.CellContentClick
    Dim senderGrid = DirectCast(sender, DataGridView)

    If TypeOf senderGrid.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso
       e.RowIndex >= 0 Then
        'TODO - Button Clicked - Execute Code Here
    End If

End Sub

Update 1 - Custom Event

If you wanted to have a little bit of fun, you can add your own event to be raised whenever a button is clicked on the DataGrid. You can't add it to the DataGrid itself, without getting messy with inheritance etc., but you can add a custom event to your form and fire it when appropriate. It's a little more code, but the upside is that you've separated out what you want to do when a button is clicked with how to determine if a button was clicked.

Just declare an event, raise it when appropriate, and handle it. It will look like this:

Event DataGridView1ButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs)

Private Sub DataGridView1_CellContentClick(sender As System.Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
    Dim senderGrid = DirectCast(sender, DataGridView)
    If TypeOf senderGrid.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso e.RowIndex >= 0 Then
        RaiseEvent DataGridView1ButtonClick(senderGrid, e)
    End If
End Sub

Private Sub DataGridView1_ButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs) Handles Me.DataGridView1ButtonClick
    'TODO - Button Clicked - Execute Code Here
End Sub

Update 2 - Extended Grid

What would be great is if we were working with a grid that just did these things for us. We could answer the initial question easily: you've added a button to your DataGridView and you want to run some code when it's clicked. Here's an approach that extends the DataGridView. It might not be worth the hassle of having to deliver a custom control with every library, but at least it maximally reuses the code used for determining if a button was clicked.

Just add this to your assembly:

Public Class DataGridViewExt : Inherits DataGridView

    Event CellButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs)

    Private Sub CellContentClicked(sender As System.Object, e As DataGridViewCellEventArgs) Handles Me.CellContentClick
        If TypeOf Me.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso e.RowIndex >= 0 Then
            RaiseEvent CellButtonClick(Me, e)
        End If
    End Sub

End Class

That's it. Never touch it again. Make sure your DataGrid is of type DataGridViewExt which should work exactly the same as a DataGridView. Except it will also raise an extra event that you can handle like this:

Private Sub DataGridView1_ButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs) _
                                      Handles DataGridView1.CellButtonClick
    'TODO - Button Clicked - Execute Code Here
End Sub

the val function called from the select will return an array if its a multiple. $('select#my_multiselect').val() will return an array of the values for the selected options - you dont need to loop through and get them yourself.

Yes. Click on the object (textbox, shape, etc.) to select the object and in the Drawing Tools | Format tab, click on Selection Pane in the Arrange group. From there, you'll see names of objects - you can double click (or press F2) on any name and rename it. By deselecting it, it becomes renamed. You can also get to this from the Home tab -> Drawing group -> Arrange drop-down -> Selection pane or by pressing ALT + F10.

Use the matplot function:

matplot(x, cbind(y1,y2),type="l",col=c("red","green"),lty=c(1,1))

use this if y1 and y2 are evaluated at the same x points. It scales the Y-axis to fit whichever is bigger (y1 or y2), unlike some of the other answers here that will clip y2 if it gets bigger than y1 (ggplot solutions mostly are okay with this).

Alternatively, and if the two lines don't have the same x-coordinates, set the axis limits on the first plot and add:

x1  <- seq(-2, 2, 0.05)
x2  <- seq(-3, 3, 0.05)
y1 <- pnorm(x1)
y2 <- pnorm(x2,1,1)

plot(x1,y1,ylim=range(c(y1,y2)),xlim=range(c(x1,x2)), type="l",col="red")
lines(x2,y2,col="green")

Am astonished this Q is 4 years old and nobody has mentioned matplot or x/ylim...

You can set the fontsize directly in the call to set_xticklabels and set_yticklabels (as noted in previous answers). This will only affect one Axes at a time.

ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)

You can also set the ticklabel font size globally (i.e. for all figures/subplots in a script) using rcParams:

import matplotlib.pyplot as plt

plt.rc('xtick',labelsize=8)
plt.rc('ytick',labelsize=8)

Or, equivalently:

plt.rcParams['xtick.labelsize']=8
plt.rcParams['ytick.labelsize']=8

Finally, if this is a setting that you would like to be set for all your matplotlib plots, you could also set these two rcParams in your matplotlibrc file:

xtick.labelsize      : 8 # fontsize of the x tick labels
ytick.labelsize      : 8 # fontsize of the y tick labels

Reliability is guaranteed at a 99.95% up-time, and Google also provides the ability to back up and restore your data, and believe it or not, storage is unlimited.

You can manage your assets with Google Cloud Storage, storing, retrieving, displaying, and deleting them. You can also quickly read and write to flat datasheets that are kept in Cloud Storage. Next in the Google Cloud lineup is BigQuery. With BigQuery, you can analyze massive amounts of data, we're talking millions of records, within seconds. Access is handled via a straightforward UI, or a Representational State Transfer, or REST interface.

Data storage is, as you might suspect, not a problem, and scales to hundreds of TB. BigQuery is accessible via a host of client libraries, including those for Java, .NET, Python, Go, Ruby, PHP, and Javascript. A SQL-like syntax called NoSQL is available which can be accessed through these client libraries, or through a web user interface. Finally, let's talk about the Google Cloud platform database options, Cloud SQL and Cloud Datastore.

There is a major difference. Cloud SQL is for relational databases, primarily MySQL, whereas Cloud Datastore is for non-relational databases using noSQL. With Cloud SQL, you have the choice of either hosting in the US, Europe, or Asia, with 100 GB of storage, and 16 GB of RAM per database instance.

Cloud Datastore is available at no charge for up to 50 K read/write instructions per month and 1 GB of data stored also per month. There is a fee if you exceed these quotas, however. App Engine can also work with other lesser known, more targeted members of the Google Cloud platform, including the Cloud Endpoints for creating API backends, Google Prediction API for data analysis and trend forecasting, or the Google Translate API, for multilingual output.

While you can do a fair amount with App Engine on its own, It's potential skyrockets when you factor in its ability to work easily and efficiently with its fellow Google Cloud platform services.

pyinstaller unpacks your data into a temporary folder, and stores this directory path in the _MEIPASS2 environment variable. To get the _MEIPASS2 dir in packed-mode and use the local directory in unpacked (development) mode, I use this:

def resource_path(relative):
    return os.path.join(
        os.environ.get(
            "_MEIPASS2",
            os.path.abspath(".")
        ),
        relative
    )

Output:

# in development
>>> resource_path("app_icon.ico")
"/home/shish/src/my_app/app_icon.ico"

# in production
>>> resource_path("app_icon.ico")
"/tmp/_MEI34121/app_icon.ico"

From https://api.jquery.com/change/:

The change event is sent to an element when its value changes. This event is limited to <input> elements, <textarea> boxes and <select> elements. For select boxes, checkboxes, and radio buttons, the event is fired immediately when the user makes a selection with the mouse, but for the other element types the event is deferred until the element loses focus.

Assuming the original date is in cell A1:

=A1-180

Works in at least Excel 2003 and 2010.

You can remove webdav module manually from GUI for the particular in IIS.
1) Goto the IIs.
2) Goto the respective site.
3) Open "Handler Mappings"
4) Scroll downn and select WebDav module. Right click on it and delete it.

Note: this will also update your web.config of the web app.

Just change the first line as follows :

include ActionView::Helpers

that will make it works.

UPDATE: For Rails 3 use:

ActionController::Base.helpers.sanitize(str)

Just for the newcomers: the recent versions of C# allows the use of ? operator to check nulls assignments

parentSplit = xNode.ParentNode.Attributes["split"]?.Value;

Try this

  List<Address> list = geoCoder.getFromLocation(location
            .getLatitude(), location.getLongitude(), 1);
    if (list != null & list.size() > 0) {
        Address address = list.get(0);
        result = address.getLocality();
        return result;

Either remove one } from end of responseText;}} or from the end of the line

FNV-1 is rumoured to be a good hash function for strings.

For long strings (longer than, say, about 200 characters), you can get good performance out of the MD4 hash function. As a cryptographic function, it was broken about 15 years ago, but for non cryptographic purposes, it is still very good, and surprisingly fast. In the context of Java, you would have to convert the 16-bit char values into 32-bit words, e.g. by grouping such values into pairs. A fast implementation of MD4 in Java can be found in sphlib. Probably overkill in the context of a classroom assignment, but otherwise worth a try.

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

JMX now uses port 7199 instead of port 8080 (as of Cassandra 0.8.xx).

This is configurable in your cassandra-env.sh file, but the default is 7199.

ORACLE_HOME needs to be at the top level of the Oracle directory structure for the database installation. From that point, Oracle knows how to find all the other files it needs. For example, the error message you get is because Oracle can't locate the message files to report errors with (should be in the various mesg directories below the oracle home. Instead of the above value you give, I would try

export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0

To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):

OPS is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.

Rank is set with a right click on a data point selected in that column and Show Values As... and Rank Largest to Smallest (there are other options) with the Base field as Player and the filter is a Value Filters, Top 10... one:

Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).

In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5 for Top 5.

If the process runs for at least a couple seconds, then you can use the following bash script, which will run the given command line then print to stderr the peak RSS (substitute for rss any other attribute you're interested in). It's somewhat lightweight, and it works for me with the ps included in Ubuntu 9.04 (which I can't say for time).

#!/usr/bin/env bash
"$@" & # Run the given command line in the background.
pid=$! peak=0
while true; do
  sleep 1
  sample="$(ps -o rss= $pid 2> /dev/null)" || break
  let peak='sample > peak ? sample : peak'
done
echo "Peak: $peak" 1>&2

You can save an image as 'png' and use the python imaging library (PIL) to convert this file to 'jpg':

import Image
import matplotlib.pyplot as plt

plt.plot(range(10))
plt.savefig('testplot.png')
Image.open('testplot.png').save('testplot.jpg','JPEG')

The original:

The JPEG image:

If you have access to the iframed page you could use something like easyXDM to make function calls in the iframe and return the data.

If you don't have access to the iframed page you will have to use a server side solution. With PHP you could do something quick and dirty like:

    <?php echo file_get_contents('http://url_of_the_iframe/content.php'); ?> 

There is a better way that is safer and will not slow down your application. How Excel is set up, a cell can have either a value or a formula; the formula can not refer to its own cell. You end up with an infinite loop, since the new value would cause another calculation... . Use a helper column to calculate the value based on what you put in the other cell. For Example:

Column A is a True or False, Column B contains a monetary value, Column C contains the folowing formula: =B1

Now, to calculate that column B will be highlighted yellow in a conditional format only if Column A is True and Column B is greater than Zero...

=AND(A1=True,C1>0)

You can then choose to hide column C

Views are acceptable when you need to ensure that complex logic is followed every time. For instance, we have a view that creates the raw data needed for all financial reporting. By having all reports use this view, everyone is working from the same data set, rather than one report using one set of joins and another forgetting to use one which gives different results.

Views are acceptable when you want to restrict users to a particular subset of data. For instance, if you do not delete records but only mark the current one as active and the older versions as inactive, you want a view to use to select only the active records. This prevents people from forgetting to put the where clause in the query and getting bad results.

Views can be used to ensure that users only have access to a set of records - for instance, a view of the tables for a particular client and no security rights on the tables can mean that the users for that client can only ever see the data for that client.

Views are very helpful when refactoring databases.

Views are not acceptable when you use views to call views which can result in horrible performance (at least in SQL Server). We almost lost a multimillion dollar client because someone chose to abstract the database that way and performance was horrendous and timeouts frequent. We had to pay for the fix too, not the client, as the performance issue was completely our fault. When views call views, they have to completely generate the underlying view. I have seen this where the view called a view which called a view and so many millions of records were generated in order to see the three the user ultimately needed. I remember one of these views took 8 minutes to do a simple count(*) of the records. Views calling views are an extremely poor idea.

Views are often a bad idea to use to update records as usually you can only update fields from the same table (again this is SQL Server, other databases may vary). If that's the case, it makes more sense to directly update the tables anyway so that you know which fields are available.

There are a few things I have started to do that I do not think are standard:

1) With the advent of properties, I no longer use "_" to prefix "private" class variables. After all, if a variable can be accessed by other classes shouldn't there be a property for it? I always disliked the "_" prefix for making code uglier, and now I can leave it out.

2) Speaking of private things, I prefer to place private method definitions within the .m file in a class extension like so:

#import "MyClass.h"

@interface MyClass ()
- (void) someMethod;
- (void) someOtherMethod;
@end

@implementation MyClass

Why clutter up the .h file with things outsiders should not care about? The empty () works for private categories in the .m file, and issues compile warnings if you do not implement the methods declared.

3) I have taken to putting dealloc at the top of the .m file, just below the @synthesize directives. Shouldn't what you dealloc be at the top of the list of things you want to think about in a class? That is especially true in an environment like the iPhone.

3.5) In table cells, make every element (including the cell itself) opaque for performance. That means setting the appropriate background color in everything.

3.6) When using an NSURLConnection, as a rule you may well want to implement the delegate method:

- (NSCachedURLResponse *)connection:(NSURLConnection *)connection
                  willCacheResponse:(NSCachedURLResponse *)cachedResponse
{
      return nil;
}

I find most web calls are very singular and it's more the exception than the rule you'll be wanting responses cached, especially for web service calls. Implementing the method as shown disables caching of responses.

Also of interest, are some good iPhone specific tips from Joseph Mattiello (received in an iPhone mailing list). There are more, but these were the most generally useful I thought (note that a few bits have now been slightly edited from the original to include details offered in responses):

4) Only use double precision if you have to, such as when working with CoreLocation. Make sure you end your constants in 'f' to make gcc store them as floats.

float val = someFloat * 2.2f;

This is mostly important when someFloat may actually be a double, you don't need the mixed-mode math, since you're losing precision in 'val' on storage. While floating-point numbers are supported in hardware on iPhones, it may still take more time to do double-precision arithmetic as opposed to single precision. References:

• Double vs float on the iPhone
• iPhone/iPad double precision math

On the older phones supposedly calculations operate at the same speed but you can have more single precision components in registers than doubles, so for many calculations single precision will end up being faster.

5) Set your properties as nonatomic. They're atomic by default and upon synthesis, semaphore code will be created to prevent multi-threading problems. 99% of you probably don't need to worry about this and the code is much less bloated and more memory-efficient when set to nonatomic.

6) SQLite can be a very, very fast way to cache large data sets. A map application for instance can cache its tiles into SQLite files. The most expensive part is disk I/O. Avoid many small writes by sending BEGIN; and COMMIT; between large blocks. We use a 2 second timer for instance that resets on each new submit. When it expires, we send COMMIT; , which causes all your writes to go in one large chunk. SQLite stores transaction data to disk and doing this Begin/End wrapping avoids creation of many transaction files, grouping all of the transactions into one file.

Also, SQL will block your GUI if it's on your main thread. If you have a very long query, It's a good idea to store your queries as static objects, and run your SQL on a separate thread. Make sure to wrap anything that modifies the database for query strings in @synchronize() {} blocks. For short queries just leave things on the main thread for easier convenience.

More SQLite optimization tips are here, though the document appears out of date many of the points are probably still good;

Here is the Best and shortest solution that works for me as of may, 2018 for Laravel 5.5

1. just cut your .htaccess file from the /public directory to the root directory and replace it content with the following code:

   <IfModule mod_rewrite.c>
       <IfModule mod_negotiation.c>
          Options -MultiViews
       </IfModule>
   
       RewriteEngine On
   
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteRule ^(.*)/$ /$1 [L,R=301]
   
       RewriteCond %{REQUEST_URI} !(\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC]
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteRule ^ server.php [L]
   
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteCond %{REQUEST_URI} !^/public/
       RewriteRule ^(css|js|images)/(.*)$ public/$1/$2 [L,NC]
   </IfModule>
   

2. Just save the .htaccess file and that is all.

3. Rename your server.php file to index.php. that is all enjoy!

Whatever the name of your dump file, it's the content which does matter.

You need to check your mydatabase.sql and find this line :

USE mydatabasename;

This name does matter, and it's the one you must use in your command :

mysql -uroot -pmypassword mydatabasename<mydatabase.sql;

Two options for you :

1. Remove USE mydatabasename; in your dump, and keep using :
   mysql -uroot -pmypassword mydatabase<mydatabase.sql;
2. Change your local database name to fit the one in your SQL dump, and use :
   mysql -uroot -pmypassword mydatabasename<mydatabase.sql;

you can use the boolean operator or: ||

if($var == 'abc' || $var == 'def' || $var == 'hij' || $var == 'klm' || $var == 'nop'){
    echo "true";
}

Well, I use this method on my site:

<a class="share-btn" href="https://www.facebook.com/sharer/sharer.php?app_id=[your_app_id]&sdk=joey&u=[full_article_url]&display=popup&ref=plugin&src=share_button" onclick="return !window.open(this.href, 'Facebook', 'width=640,height=580')">

Works perfectly.

MSDocs state this for your scenario:

In order to execute the first time, PackageManagement requires an internet connection to download the Nuget package provider. However, if your computer does not have an internet connection and you need to use the Nuget or PowerShellGet provider, you can download them on another computer and copy them to your target computer. Use the following steps to do this:

1. Run Install-PackageProvider -Name NuGet -RequiredVersion 2.8.5.201 -Force to install the provider from a computer with an internet connection.

2. After the install, you can find the provider installed in $env:ProgramFiles\PackageManagement\ReferenceAssemblies\\\<ProviderName\>\\\<ProviderVersion\> or $env:LOCALAPPDATA\PackageManagement\ProviderAssemblies\\\<ProviderName\>\\\<ProviderVersion\>.

3. Place the folder, which in this case is the Nuget folder, in the corresponding location on your target computer. If your target computer is a Nano server, you need to run Install-PackageProvider from Nano Server to download the correct Nuget binaries.

4. Restart PowerShell to auto-load the package provider. Alternatively, run Get-PackageProvider -ListAvailable to list all the package providers available on the computer. Then use Import-PackageProvider -Name NuGet -RequiredVersion 2.8.5.201 to import the provider to the current Windows PowerShell session.

What is the utility of an only one Ampersand? This morning, I made a launcher in the XFCE panel (in Manjaro+XFCE) to launch 2 passwords managers simultaneously:

sh -c "keepassx && password-gorilla"
or
sh -c "keepassx; password-gorilla"

But it does not work as I want. I.E., the first app starts but the second starts only when the previous is closed

However, I found that (with only one ampersand):

sh -c "keepassx & password-gorilla"

and it works as I want now...

Solution:
1. Shut down Pg server

2. It will disconnect all active connection
3. Restart Pg Server
4. Try your command

 var svg; // if you have variable declared and not assigned value.
 // then you make a mistake by appending elements to that before creating element    
 svg.appendChild(document.createElement("g"));
 // at some point you assign to svg
 svg = document.createElementNS('http://www.w3.org/2000/svg', "svg")
 // then you put it in DOM
 document.getElementById("myDiv").appendChild(svg)
 // it wont render unless you manually change myDiv DOM with DevTools

// to fix assign before you append
var svg = createElement("svg", [
    ["version", "1.2"],
    ["xmlns:xlink", "http://www.w3.org/1999/xlink"],
    ["aria-labelledby", "title"],
    ["role", "img"],
    ["class", "graph"]
]);
function createElement(tag, attributeArr) {
      // .createElementNS  NS is must! Does not draw without
      let elem = document.createElementNS('http://www.w3.org/2000/svg', tag);             
      attributeArr.forEach(element => elem.setAttribute(element[0], element[1]));
      return elem;
}
// extra: <circle> for example requires attributes to render. Check if missing.

grep -v is your friend:

grep --help | grep invert  

-v, --invert-match select non-matching lines

Also check out the related -L (the complement of -l).

-L, --files-without-match only print FILE names containing no match

It looks like others had this problem also, and there is a simple Python script now, for converting output of mysqldump into CSV files.

wget https://raw.githubusercontent.com/jamesmishra/mysqldump-to-csv/master/mysqldump_to_csv.py

If the text is a simple markup and has existing anchors, stage the existing anchor tags first, swap out the urls, then replace the staged markers.

$text = '
Lorem Ipsum is simply dummy text found by searching http://google.com/?q=lorem in your <a href=https://www.mozilla.org/en-US/firefox/>Firefox</a>,
<a href="https://www.apple.com/safari/">Safari</a>, or https://www.google.com/chrome/ browser.

Link replacements will first stage existing anchor tags, replace each with a marker, then swap out the remaining links.
Links should be properly encoded.  If links are not separated from surrounding content like a trailing "." period then they it will be included in the link.
Links that are not encoded properly may create a problem, so best to use this when you know the text you are processing is not mixed HTML.

Same thing happened to me. Eventually my solution was to navigate to the repository using terminal (on mac) and create a new js file with a slightly different name. It linked immediately so i copied contents of original file to new one. You also might want to lose the first / after src= and use "".

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework.

REST

RESTs sweet spot is when you are exposing a public API over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP

SOAP brings it’s own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each implement some business logic through different interfaces.

Though SOAP is commonly referred to as “web services” this is a misnomer. SOAP has very little if anything to do with the Web. REST provides true “Web services” based on URIs and HTTP.

Reference: http://spf13.com/post/soap-vs-rest

And finally: What they could be referring to is REST vs. RPC See this: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/

You will get all the necessary data in the ResolveInfo to start a application. You can check ResolveInfo javadoc here.

Travis R is correct. (I wish I could upvote ya.) I just got this working myself. With these routes:

resources :articles do
  resources :comments
end

You get paths like:

/articles/42
/articles/42/comments/99

routed to controllers at

app/controllers/articles_controller.rb
app/controllers/comments_controller.rb

just as it says at http://guides.rubyonrails.org/routing.html#nested-resources, with no special namespaces.

But partials and forms become tricky. Note the square brackets:

<%= form_for [@article, @comment] do |f| %>

Most important, if you want a URI, you may need something like this:

article_comment_path(@article, @comment)

Alternatively:

[@article, @comment]

as described at http://edgeguides.rubyonrails.org/routing.html#creating-paths-and-urls-from-objects

For example, inside a collections partial with comment_item supplied for iteration,

<%= link_to "delete", article_comment_path(@article, comment_item),
      :method => :delete, :confirm => "Really?" %>

What jamuraa says may work in the context of Article, but it did not work for me in various other ways.

There is a lot of discussion related to nested resources, e.g. http://weblog.jamisbuck.org/2007/2/5/nesting-resources

Interestingly, I just learned that most people's unit-tests are not actually testing all paths. When people follow jamisbuck's suggestion, they end up with two ways to get at nested resources. Their unit-tests will generally get/post to the simplest:

# POST /comments
post :create, :comment => {:article_id=>42, ...}

In order to test the route that they may prefer, they need to do it this way:

# POST /articles/42/comments
post :create, :article_id => 42, :comment => {...}

I learned this because my unit-tests started failing when I switched from this:

resources :comments
resources :articles do
  resources :comments
end

to this:

resources :comments, :only => [:destroy, :show, :edit, :update]
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

I guess it's ok to have duplicate routes, and to miss a few unit-tests. (Why test? Because even if the user never sees the duplicates, your forms may refer to them, either implicitly or via named routes.) Still, to minimize needless duplication, I recommend this:

resources :comments
resources :articles do
  resources :comments, :only => [:create, :index, :new]
end

Sorry for the long answer. Not many people are aware of the subtleties, I think.

In addition to the answers already given, if you want to create a new directory, you could use this function:

def mkdir_p(mypath):
    '''Creates a directory. equivalent to using mkdir -p on the command line'''

    from errno import EEXIST
    from os import makedirs,path

    try:
        makedirs(mypath)
    except OSError as exc: # Python >2.5
        if exc.errno == EEXIST and path.isdir(mypath):
            pass
        else: raise

and then:

import matplotlib
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(100))

# Create new directory
output_dir = "some/new/directory"
mkdir_p(output_dir)

fig.savefig('{}/graph.png'.format(output_dir))

A control or window object in Windows Forms is just a wrapper around a Win32 window identified by a handle (sometimes called HWND). Most things you do with the control will eventually result in a Win32 API call that uses this handle. The handle is owned by the thread that created it (typically the main thread), and shouldn't be manipulated by another thread. If for some reason you need to do something with the control from another thread, you can use Invoke to ask the main thread to do it on your behalf.

For instance, if you want to change the text of a label from a worker thread, you can do something like this:

theLabel.Invoke(new Action(() => theLabel.Text = "hello world from worker thread!"));

For anyone stumbling across this question refer to this documentation from MS - it has really good details regarding FormsAuthentication Timeout setting.

This doc explains in detail about the comment bmode is making in the Accepted Answer - about the Persistent Cookie (Session vs Expires)

https://docs.microsoft.com/en-us/aspnet/web-forms/overview/older-versions-security/introduction/forms-authentication-configuration-and-advanced-topics-cs#specifying-the-tickets-timeout-value

According to this site add

CONFIG += c++11

to your .pro file (see at the bottom of that web page). It requires Qt 5.

The other answers, suggesting

QMAKE_CXXFLAGS += -std=c++11 (or QMAKE_CXXFLAGS += -std=c++0x)

also work with Qt 4.8 and gcc / clang.

Short answer: Why not?

Longer answer: The time itself doesn't really matter, as long as everyone who uses it agrees on its value. As 1/1/70 has been in use for so long, using it will make you code as understandable as possible for as many people as possible.

There's no great merit in choosing an arbitrary epoch just to be different.

max is built in function which takes first argument an iterable (like list or tuple)

keyword argument key has it's default value None but it accept function to evaluate, consider it as wrapper which evaluates iterable based on function

Consider this example dictionary:

d = {'aim':99, 'aid': 45, 'axe': 59, 'big': 9, 'short': 995, 'sin':12, 'sword':1, 'friend':1000, 'artwork':23}

Ex:

>>> max(d.keys())
'sword'

As you can see if you only pass the iterable without kwarg(a function to key) it is returning maximum value of key(alphabetically)

Ex. Instead of finding max value of key alphabetically you might need to find max key by length of key:

>>>max(d.keys(), key=lambda x: len(x))
'artwork'

in this example lambda function is returning length of key which will be iterated hence while evaluating values instead of considering alphabetically it will keep track of max length of key and returns key which has max length

Ex.

>>> max(d.keys(), key=lambda x: d[x])
'friend'

in this example lambda function is returning value of corresponding dictionary key which has maximum value

My need was sort based on date.

So, I used Comparable and it worked easily for me.

public int compareTo(GoogleCalendarBean o) {
    // TODO Auto-generated method stub
    return eventdate.compareTo(o.getEventdate());
}

One restriction with Comparable is that they cannot used for Collections other than List.

For people that want to response according to http status code, you can use the ErrorController way:

@Controller
public class CustomErrorController extends BasicErrorController {

    public CustomErrorController(ServerProperties serverProperties) {
        super(new DefaultErrorAttributes(), serverProperties.getError());
    }

    @Override
    public ResponseEntity error(HttpServletRequest request) {
        HttpStatus status = getStatus(request);
        if (status.equals(HttpStatus.INTERNAL_SERVER_ERROR)){
            return ResponseEntity.status(status).body(ResponseBean.SERVER_ERROR);
        }else if (status.equals(HttpStatus.BAD_REQUEST)){
            return ResponseEntity.status(status).body(ResponseBean.BAD_REQUEST);
        }
        return super.error(request);
    }
}

The ResponseBean here is my custom pojo for response.

You can do <input type="text" pattern="\d*">. This will cause the numeric keyboard to appear.

See here for more detail: Text, Web, and Editing Programming Guide for iOS

<form>_x000D_
  <input type="text" pattern="\d*">_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

Check if element is visible in viewport using jquery:

First determine the top and bottom positions of the element. Then determine the position of the viewport's bottom (relative to the top of your page) by adding the scroll position to the viewport height.

If the bottom position of the viewport is greater than the element's top position AND the top position of the viewport is less than the element's bottom position, the element is in the viewport (at least partially). In simpler terms, when any part of the element is between the top and bottom bounds of your viewport, the element is visible on your screen.

Now you can write an if/else statement, where the if statement only runs when the above condition is met.

The code below executes what was explained above:

// this function runs every time you are scrolling

$(window).scroll(function() {
    var top_of_element = $("#element").offset().top;
    var bottom_of_element = $("#element").offset().top + $("#element").outerHeight();
    var bottom_of_screen = $(window).scrollTop() + $(window).innerHeight();
    var top_of_screen = $(window).scrollTop();

    if ((bottom_of_screen > top_of_element) && (top_of_screen < bottom_of_element)){
        // the element is visible, do something
    } else {
        // the element is not visible, do something else
    }
});

This answer is a summary of what Chris Bier and Andy were discussing below. I hope it helps anyone else who comes across this question while doing research like I did. I also used an answer to the following question to formulate my answer: Show Div when scroll position.

openssl s_client -connect api.cscglobal.com:443 < /dev/null 2>/dev/null  | openssl x509 -text -in /dev/stdin | grep "Signature Algorithm" | cut -d ":" -f2 | uniq | sed '/^$/d' | sed -e 's/^[ \t]*//'

I use some css like this (based on css tricks):

@media screen and (min-width: 320px) and (max-width: 767px) and (orientation: portrait) {
  html {
    transform: rotate(-90deg);
    transform-origin: left top;
    width: 100vh;
    height: 100vw;
    overflow-x: hidden;
    position: absolute;
    top: 100%;
    left: 0;
  }
}

There is an codeproject project avaliable HERE that provides this functuanility.

Following many threads here on SO and other boards this cant be done with the normal MessageBox.

Edit:

I have an idea that is a bit ehmmm yeah..

Use a timer and start in when the MessageBox appears. If your MessageBox only listens to the OK Button (only 1 possibility) then use the OnTick-Event to emulate an ESC-Press with SendKeys.Send("{ESC}"); and then stop the timer.

You can not add an element to an array, since arrays, in Java, are fixed-length. However, you could build a new array from the existing one using Arrays.copyOf(array, size) :

public static void main(String[] args) {
    int[] array = new int[] {1, 2, 3};
    System.out.println(Arrays.toString(array));
    array = Arrays.copyOf(array, array.length + 1); //create new array from old array and allocate one more element
    array[array.length - 1] = 4;
    System.out.println(Arrays.toString(array));
}

I would still recommend to drop working with an array and use a List.

On Selenium >= 3.41 (C#) the rigth syntax is:

webDriver = webDriver.SwitchTo().Frame(webDriver.FindElement(By.Name("icontent")));

From a Stack Overflow reference

It did not work with value="" if the browser already saves the value so you should add.

For an input tag there's the attribute autocomplete you can set:

<input type="text" autocomplete="off" />

You can use autocomplete for a form too.

Indeed a plugin for a simple blink effect is overkill. So after experimenting with various solutions, I have choosen between one line of javascript and a CSS class that controls exactly how I want to blink the elements (in my case for the blink to work I only need to change the background to transparent, so that the text is still visible):

JS:

$(document).ready(function () {
        setInterval(function () { $(".blink").toggleClass("no-bg"); }, 1000);
    });

CSS:

span.no-bg {
    background-color: transparent;
}

Full example at this js fiddle.

You might want to think about a better pattern for dealing with data of this type.

No self-prespecting SQL driver will tell you how many rows your query will return before returning the rows, because the answer might change (unless you use a Transaction, which creates problems of its own.)

The number of rows won't change - google for ACID and SQL.

The modern solution that doesn't need a 40 KB library:

Intl.DateTimeFormat is the non-culturally imperialistic way to format a date/time.

// Setup once
var options = {
    //weekday: 'long',
    //month: 'short',
    //year: 'numeric',
    //day: 'numeric',
    hour: 'numeric',
    minute: 'numeric',
    second: 'numeric'
},
intlDate = new Intl.DateTimeFormat( undefined, options );

// Reusable formatter
var timeStamp = 1412743273;
console.log( intlDate.format( new Date( 1000 * timeStamp ) ) );

Following is the util function to get current timestamp in milliseconds:

#include <sys/time.h>

long long current_timestamp() {
    struct timeval te; 
    gettimeofday(&te, NULL); // get current time
    long long milliseconds = te.tv_sec*1000LL + te.tv_usec/1000; // calculate milliseconds
    // printf("milliseconds: %lld\n", milliseconds);
    return milliseconds;
}

About timezone:

gettimeofday() support to specify timezone, I use NULL, which ignore the timezone, but you can specify a timezone, if need.

@Update - timezone

Since the long representation of time is not relevant to or effected by timezone itself, so setting tz param of gettimeofday() is not necessary, since it won't make any difference.

And, according to man page of gettimeofday(), the use of the timezone structure is obsolete, thus the tz argument should normally be specified as NULL, for details please check the man page.

strip() is a method for strings, you are calling it on a list, hence the error.

>>> 'strip' in dir(str)
True
>>> 'strip' in dir(list)
False

To do what you want, just do

>>> l = ['Facebook;Google+;MySpace', 'Apple;Android']
>>> l1 = [elem.strip().split(';') for elem in l]
>>> print l1
[['Facebook', 'Google+', 'MySpace'], ['Apple', 'Android']]

Since, you want the elements to be in a single list (and not a list of lists), you have two options.

1. Create an empty list and append elements to it.
2. Flatten the list.

To do the first, follow the code:

>>> l1 = []
>>> for elem in l:
        l1.extend(elem.strip().split(';'))  
>>> l1
['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']

To do the second, use itertools.chain

>>> l1 = [elem.strip().split(';') for elem in l]
>>> print l1
[['Facebook', 'Google+', 'MySpace'], ['Apple', 'Android']]
>>> from itertools import chain
>>> list(chain(*l1))
['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']

TL;DR $PATH fix

1. Use pip install --user package_name to install a package that should include CLI executables.
2. Launch a python shell and import package_name
3. Find where lib/python/... occurs in the output and replace it all with bin
4. It's likely to be $HOME/Library/Python/2.7/bin

Details

Because of the new System Integrity Protection in macOS 10.11 El Capitan, you can no longer sudo pip install. We won't debate the merits of that here.

Another answer explains that you should pip install --user which is correct. But they sent you to the back alleys to figure out what to do about your $PATH so that you could get access to installed executables. Luckily, I've already solved a similar need for an unrelated question.

Here is a transcript of how I solved the problem on one of my systems. I'm including it all rather just than the $PATH that worked for me, because your system may be different from mine. This process should work for everybody.

To clear up some confusion you have to understand the roles of the client secret and the user password, which are very different.

The client is an app/website/program/..., backed by a server, that wants to authenticate a user by using a third-party authentication service. The client secret is a (random) string that is known to both this client and the authentication server. Using this secret the client can identify itself with the authentication server, receiving authorization to request access tokens.

To get the initial access token and refresh token, what is required is:

• The user ID
• The user password
• The client ID
• The client secret

To get a refreshed access token however the client uses the following information:

• The client ID
• The client secret
• The refresh token

This clearly shows the difference: when refreshing, the client receives authorization to refresh access tokens by using its client secret, and can thus re-authenticate the user using the refresh token instead of the user ID + password. This effectively prevents the user from having to re-enter his/her password.

This also shows that losing a refresh token is no problem because the client ID and secret are not known. It also shows that keeping the client ID and client secret secret is vital.

In Rails 3, Application specific custom configuration data can be placed in the application configuration object. The configuration can be assigned in the initialization files or the environment files -- say for a given application MyApp:

MyApp::Application.config.custom_config_variable = :my_config_setting

or

Rails.configuration.custom_config_variable = :my_config_setting

To read the setting, simply call the configuration variable without setting it:

Rails.configuration.custom_config_variable
=> :my_config_setting

UPDATE Rails 4

In Rails 4 there a new way for this => http://guides.rubyonrails.org/configuring.html#custom-configuration

Check your short_open_tag setting (use <?php phpinfo() ?> to see its current setting).

Here is another alternative using Guava

List<Object> lst ...    
List<String> ls = Lists.transform(lst, Functions.toStringFunction());

http://api.jquery.com/jQuery.inArray/

if ($.inArray('example', myArray) != -1)
{
  // found it
}

  Connect to database:

  Method 1 : enter to db : sudo -u postgres psql

  Connect to db : \c dbname

  Method 2 : directly connect to db : sudo -u postgres psql -d my_database_name

Don't use in Browser

In the browser, use document.querySelect('[attribute-name]').

But if you're unit testing and your mocked dom has a flakey querySelector implementation, this will do the trick.

This is @kevinfahy's answer, just trimmed down to be a bit with ES6 fat arrow functions and by converting the HtmlCollection into an array at the cost of readability perhaps.

So it'll only work with an ES6 transpiler. Also, I'm not sure how performant it'll be with a lot of elements.

function getElementsWithAttribute(attribute) {
  return [].slice.call(document.getElementsByTagName('*'))
    .filter(elem => elem.getAttribute(attribute) !== null);
}

And here's a variant that will get an attribute with a specific value

function getElementsWithAttributeValue(attribute, value) {
  return [].slice.call(document.getElementsByTagName('*'))
    .filter(elem => elem.getAttribute(attribute) === value);
}

In MySQL, use the JSON type.

Contra the answers above, the SQL standard has included array types for almost twenty years; they are useful, even if MySQL has not implemented them.

In your example, however, you'll likely want to create three tables: person and fruit, then person_fruit to join them.

DROP TABLE IF EXISTS person_fruit;
DROP TABLE IF EXISTS person;
DROP TABLE IF EXISTS fruit;

CREATE TABLE person (
  person_id   INT           NOT NULL AUTO_INCREMENT,
  person_name VARCHAR(1000) NOT NULL,
  PRIMARY KEY (person_id)
);

CREATE TABLE fruit (
  fruit_id    INT           NOT NULL AUTO_INCREMENT,
  fruit_name  VARCHAR(1000) NOT NULL,
  fruit_color VARCHAR(1000) NOT NULL,
  fruit_price INT           NOT NULL,
  PRIMARY KEY (fruit_id)
);

CREATE TABLE person_fruit (
  pf_id     INT NOT NULL AUTO_INCREMENT,
  pf_person INT NOT NULL,
  pf_fruit  INT NOT NULL,
  PRIMARY KEY (pf_id),
  FOREIGN KEY (pf_person) REFERENCES person (person_id),
  FOREIGN KEY (pf_fruit) REFERENCES fruit (fruit_id)
);

INSERT INTO person (person_name)
VALUES
  ('John'),
  ('Mary'),
  ('John'); -- again

INSERT INTO fruit (fruit_name, fruit_color, fruit_price)
VALUES
  ('apple', 'red', 1),
  ('orange', 'orange', 2),
  ('pineapple', 'yellow', 3);

INSERT INTO person_fruit (pf_person, pf_fruit)
VALUES
  (1, 1),
  (1, 2),
  (2, 2),
  (2, 3),
  (3, 1),
  (3, 2),
  (3, 3);

If you wish to associate the person with an array of fruits, you can do so with a view:

DROP VIEW IF EXISTS person_fruit_summary;
CREATE VIEW person_fruit_summary AS
  SELECT
    person_id                                                                                              AS pfs_person_id,
    max(person_name)                                                                                       AS pfs_person_name,
    cast(concat('[', group_concat(json_quote(fruit_name) ORDER BY fruit_name SEPARATOR ','), ']') as json) AS pfs_fruit_name_array
  FROM
    person
    INNER JOIN person_fruit
      ON person.person_id = person_fruit.pf_person
    INNER JOIN fruit
      ON person_fruit.pf_fruit = fruit.fruit_id
  GROUP BY
    person_id;

The view shows the following data:

+---------------+-----------------+----------------------------------+
| pfs_person_id | pfs_person_name | pfs_fruit_name_array             |
+---------------+-----------------+----------------------------------+
|             1 | John            | ["apple", "orange"]              |
|             2 | Mary            | ["orange", "pineapple"]          |
|             3 | John            | ["apple", "orange", "pineapple"] |
+---------------+-----------------+----------------------------------+

In 5.7.22, you'll want to use JSON_ARRAYAGG, rather than hack the array together from a string.

Here is a way to handle duplicate tuple "keys":

# An example
l = [('A', 1), ('B', 2), ('C', 3), ('A', 5), ('D', 0), ('D', 9)]

# A solution
d = dict()
[d [t [0]].append(t [1]) if t [0] in list(d.keys()) 
 else d.update({t [0]: [t [1]]}) for t in l]
d

OUTPUT: {'A': [1, 5], 'B': [2], 'C': [3], 'D': [0, 9]}

What you're asking about is multiple inheritance, and it's very problematic for a number of reasons. Multiple inheritance was specifically avoided in Java; the choice was made to support multiple interface implementation, instead, which is the appropriate workaround.

Java9 uses byte[] to store String.value, so you can only get about 1GB Strings in Java9. Java8 on the other hand can have 2GB Strings.

By character I mean "char"s, some character is not representable in BMP(like some of the emojis), so it will take more(currently 2) chars.

If anyone wants to enable dark mode, you may follow the below steps

• Open your Notepad++, and select “Settings” on the menu bar, and choose “Style configurator”.
• Select theme “Obsidian” (you can choose other dark themes)
• Click on Save&Colse

Here is the way to do it:

#!/bin/sh

abort()
{
    echo >&2 '
***************
*** ABORTED ***
***************
'
    echo "An error occurred. Exiting..." >&2
    exit 1
}

trap 'abort' 0

set -e

# Add your script below....
# If an error occurs, the abort() function will be called.
#----------------------------------------------------------
# ===> Your script goes here
# Done!
trap : 0

echo >&2 '
************
*** DONE *** 
************
'

One technique I utilize is to redirect output to an ASCII file using the Out-File cmdlet.

For example, I often run SQL scripts that create another SQL script to execute in Oracle. With simple redirection (">"), the output will be in UTF-16 which is not recognized by SQLPlus. To work around this:

sqlplus -s / as sysdba "@create_sql_script.sql" |
Out-File -FilePath new_script.sql -Encoding ASCII -Force

The generated script can then be executed via another SQLPlus session without any Unicode worries:

sqlplus / as sysdba "@new_script.sql" |
tee new_script.log

A simpler but equally effective option would be:

+ theme_bw(base_size=X)

You need to prevent the default event (following the link), otherwise your link will load a new page:

    $(document).ready(function(){
        $('.play_navigation a').click(function(e){
            e.preventDefault();
            console.log("this is the click");
        });
    });

As pointed out in comments, if your link has no href, then it's not a link, use something else.

Not working? Your code is A MESS! and ready() events everywhere... clean it, put all your scripts in ONE ready event and then try again, it will very likely sort things out.

8 bit and 16 bit pointers are used in most low profile microcontrollers. That means every washing machine, micro, fridge, older TVs, and even cars.

You could say these have nothing to do with real world programming. But here is one real world example: Arduino with 1-2-4k ram (depending on chip) with 2 byte pointers.

It's recent, cheap, accessible for everyone and worths coding for.

For only a small amount of objects the update_or_create works well, but if you're doing over a large collection it won't scale well. update_or_create always first runs a SELECT and thereafter an UPDATE.

for the_bar in bars:
    updated_rows = SomeModel.objects.filter(bar=the_bar).update(foo=100)
        if not updated_rows:
            # if not exists, create new
            SomeModel.objects.create(bar=the_bar, foo=100)

This will at best only run the first update-query, and only if it matched zero rows run another INSERT-query. Which will greatly increase your performance if you expect most of the rows to actually be existing.

It all comes down to your use case though. If you are expecting mostly inserts then perhaps the bulk_create() command could be an option.

You should instantiate your ArrayList before trying to add items:

private List<String> species = new ArrayList<String>();

In WSDL, if you look at the Binding section, you will clearly see that soap binding is explicitly mentioned if the service uses soap 1.2. refer the below sample.

    <input><soap12:body use="literal"/></input>
    <output><soap12:body use="literal"/></output>

    <soap12:operation soapAction=""/>
    <input><soap12:body use="literal"/></input>
    <output><soap12:body use="literal"/></output>
</operation>
</binding>

if the web service use soap 1.1, it will not explicitly define any soap version in the WSDL file under binding section. refer the below sample.

<binding name="EmployeeServiceImplPortBinding" type="tns:EmployeeServiceImpl">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc"/>
<operation name="findEmployeeById">
    <soap:operation soapAction=""/>
    <input><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></input>
    <output><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></output>
</operation><operation name="create">
    <soap:operation soapAction=""/>
    <input><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></input>
    <output><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></output>
</operation>
</binding>

How to determine the SOAP version of the SOAP message?

but remember that this is not much recommended way to determine the soap version that your web services uses. the version of the soap message can be determined using one of following ways.

1. checking the namespace of the soap message

SOAP 1.1  namespace : http://schemas.xmlsoap.org/soap/envelope

SOAP 1.2 namespace  : http://www.w3.org/2003/05/soap-envelope

2. checking the transport binding information (http header information) of the soap message

SOAP 1.1 : user text/xml for the Context-Type

   POST /MyService HTTP/1.1
   Content-Type: text/xml; charset="utf-8"
   Content-Length: xxx
   SOAPAction: "urn:uuid:myaction"

SOAP 1.2 : user application/soap+xml for the Context-Type

   POST /MyService HTTP/1.1
   Content-Type: application/soap+xml; charset="utf-8"
   Content-Length: xxx
   SOAPAction: "urn:uuid:myaction"

3. using SOAP fault information

The structure of a SOAP fault message between the two versions are different.

I'm assuming you mean that you don't care which row is used to obtain the title, id, and commentname values (you have "rob" for all of the rows, but I don't know if that is actually something that would be enforced or not in your data model). If so, then you can use windowing functions to return the first row for a given email address:

select
    id,
    title,
    email,
    commentname

from
(
select 
    *, 
    row_number() over (partition by email order by id) as RowNbr 

from YourTable
) source

where RowNbr = 1

The problem might not just be the path xml.

Following is my fix:

Looking into the root course in android.support.v4.content.FileProvider$SimplePathStrategy.getUriForFile():

    public File getFileForUri(Uri uri) {
        String path = uri.getEncodedPath();

        final int splitIndex = path.indexOf('/', 1);
        final String tag = Uri.decode(path.substring(1, splitIndex));
        path = Uri.decode(path.substring(splitIndex + 1));

        final File root = mRoots.get(tag); // mRoots is parsed from path xml
        if (root == null) {
            throw new IllegalArgumentException("Unable to find configured root for " + uri);
        }

        // ...
    }

This means mRoots should contains the tag of requested uri. So I write some code to print mRoots and tag of uri, and then easily find the tags do not match.

It comes out that setting provider authority as ${applicationID}.provider is a stupid idea! This authority is so common that might be used by other providers, which will mess up the path config!

'So from this discussion i am thinking this should be the code then.

Sub Button1_Click()
    Dim excel As excel.Application
    Dim wb As excel.Workbook
    Dim sht As excel.Worksheet
    Dim f As Object

    Set f = Application.FileDialog(3)
    f.AllowMultiSelect = False
    f.Show

    Set excel = CreateObject("excel.Application")
    Set wb = excel.Workbooks.Open(f.SelectedItems(1))
    Set sht = wb.Worksheets("Data")

    sht.Activate
    sht.Columns("A:G").Copy
    Range("A1").PasteSpecial Paste:=xlPasteValues


    wb.Close
End Sub

'Let me know if this is correct or a step was missed. Thx.

I can see many answers, not really addressing the three questions of the OP.

1) A word on performance: byte arrays are likely unefficient unless you can use an exact pixel byte ordering which matches to your display adapters current resolution and color depth.

To achieve the best drawing performance, simply convert your image to a BufferedImage which is generated with a type corresponding to your current graphics configuration. See createCompatibleImage at https://docs.oracle.com/javase/tutorial/2d/images/drawonimage.html

These images will be automatically cached on the display card memory after drawing a few times without any programming effort (this is standard in Swing since Java 6), and therefore the actual drawing will take negligible amount of time - if you did not change the image.

Altering the image will come with an additional memory transfer between main memory and GPU memory - which is slow. Avoid "redrawing" the image into a BufferedImage therefore, avoid doing getPixel and setPixel at all means.

For example, if you are developing a game, instead of drawing all the game actors to a BufferedImage and then to a JPanel, it is a lot faster to load all actors as smaller BufferedImages, and draw them one by one in your JPanel code at their proper position - this way there is no additional data transfer between the main memory and GPU memory except of the initial transfer of the images for caching.

ImageIcon will use a BufferedImage under the hood - but basically allocating a BufferedImage with the proper graphics mode is the key, and there is no effort to do this right.

2) The usual way of doing this is to draw a BufferedImage in an overridden paintComponent method of the JPanel. Although Java supports a good amount of additional goodies such as buffer chains controlling VolatileImages cached in the GPU memory, there is no need to use any of these since Java 6 which does a reasonably good job without exposing all of these details of GPU acceleration.

Note that GPU acceleration may not work for certain operations, such as stretching translucent images.

3) Do not add. Just paint it as mentioned above:

@Override
protected void paintComponent(Graphics g) {
    super.paintComponent(g);
    g.drawImage(image, 0, 0, this); 
}

"Adding" makes sense if the image is part of the layout. If you need this as a background or foreground image filling the JPanel, just draw in paintComponent. If you prefer brewing a generic Swing component which can show your image, then it is the same story (you may use a JComponent and override its paintComponent method) - and then add this to your layout of GUI components.

4) How to convert the array to a Bufferedimage

Converting your byte arrays to PNG, then loading it is quite resource intensive. A better way is to convert your existing byte array to a BufferedImage.

For that: do not use for loops and copy pixels. That is very very slow. Instead:

• learn the preferred byte structure of the BufferedImage (nowadays it is safe to assume RGB or RGBA, which is 4 bytes per pixel)
• learn the scanline and scansize in use (e.g. you might have a 142 pixels wide image - but in the real life that will be stored as a 256 pixel wide byte array since it is faster to process that and mask the unused pixes by the GPU hardware)
• then once you have an array build according to these principles, the setRGB array method of the BufferedImage can copy your array to the BufferedImage.

The heading looks bold because of its large size, if you have applied bold or want to change behaviour, you can do:

h1 { font-weight:normal; }

Inline event handler

In the most simple way, you can use the confirm() function in an inline onclick handler.

<a href="delete.php?id=22" onclick="return confirm('Are you sure?')">Link</a>

Advanced event handling

But normally you would like to separate your HTML and Javascript, so I suggest you don't use inline event handlers, but put a class on your link and add an event listener to it.

<a href="delete.php?id=22" class="confirmation">Link</a>
...
<script type="text/javascript">
    var elems = document.getElementsByClassName('confirmation');
    var confirmIt = function (e) {
        if (!confirm('Are you sure?')) e.preventDefault();
    };
    for (var i = 0, l = elems.length; i < l; i++) {
        elems[i].addEventListener('click', confirmIt, false);
    }
</script>

This example will only work in modern browsers (for older IEs you can use attachEvent(), returnValue and provide an implementation for getElementsByClassName() or use a library like jQuery that will help with cross-browser issues). You can read more about this advanced event handling method on MDN.

jQuery

I'd like to stay far away from being considered a jQuery fanboy, but DOM manipulation and event handling are two areas where it helps the most with browser differences. Just for fun, here is how this would look with jQuery:

<a href="delete.php?id=22" class="confirmation">Link</a>
...
<!-- Include jQuery - see http://jquery.com -->
<script type="text/javascript">
    $('.confirmation').on('click', function () {
        return confirm('Are you sure?');
    });
</script>

Since jQuery is tagged, here's an easy / user-friendly way to validate a field that must be a date (you will need the jQuery validation plugin):

html

<form id="frm">
<input id="date_creation" name="date_creation" type="text" />
</form>

jQuery

$('#frm').validate({
  rules: {
    date_creation: {
      required: true,
      date: true
    }
  }
});

DEMO + Example

UPDATE: After some digging, I found no evidence of a ready-to-go parameter to set a specific date format.

However, you can plug in the regex of your choice in a custom rule :)

$.validator.addMethod(
    "myDateFormat",
    function(value, element) {
        // yyyy-mm-dd
        var re = /^\d{4}-\d{1,2}-\d{1,2}$/;

        // valid if optional and empty OR if it passes the regex test
        return (this.optional(element) && value=="") || re.test(value);
    }
);

$('#frm').validate({
  rules: {
    date_creation: {
      // not optional
      required: true,
      // valid date
      date: true
    }
  }
});

This new rule would imply an update on your markup:

<input id="date_creation" name="date_creation" type="text" class="myDateFormat" />

Linux

php --info | grep error 

The terminal will output the error log location.

Windows

php --info | findstr /r /c:"error_log"

The command prompt will output the error log location

To set the log location

Open your php.ini and add the following line:

error_log = /log/myCustomLog.log

_{Thanks @chelmertez, @Boom for these (comments on the question).}

The following function should do what you want exactly:

hush=function(code){
  sink("NUL") # use /dev/null in UNIX
  tmp = code
  sink()
  return(tmp)
}

For example with the function here:

foo=function(){
  print("BAR!")
  return(42)
}

running

x = hush(foo())

Will assign 42 to x but will not print "BAR!" to STDOUT

Note than in a UNIX OS you will need to replace "NUL" with "/dev/null"

You can close the connection with

mongoose.connection.close()

I think this answers the question best, it actually changes the alpha value of something that has been drawn already. Maybe this wasn't part of the api when this question was asked.

Given 2d context c.

function reduceAlpha(x, y, w, h, dA) {
    let screenData = c.getImageData(x, y, w, h);
    for(let i = 3; i < screenData.data.length; i+=4){
        screenData.data[i] -= dA; //delta-Alpha
    }
    c.putImageData(screenData, x, y );
}

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

This discussion has so far ignored classloader considerations. Strictly speaking, Java static fields are shared between all instances of a class for a given classloader.

UPDATE:

Upon learning flex recently, there is a cleaner way (no tables and less css). Set the wrapper as display: flex; and to center it's children give it the properties align-items: center; for (vertical) and justify-content: center; (horizontal) centering.

See this updated JS Fiddle

Strange that nobody suggested this before.. I always use tables to do this.
Simply make a wrapper have display: table and center stuff inside it with text-align: center for horizontal and vertical-align: middle for vertical alignment.

<div class='wrapper'>
  <i class='icon fa fa-bars'></i>
</div>

and some sass like this

.wrapper{
  display: table; 

  i{
    display: table-cell;
    vertical-align: middle;
    text-align: center;
  }

}

or see this JS Fiddle

For the URI query use urlencode/urldecode; for anything else use rawurlencode/rawurldecode.

The difference between urlencode and rawurlencode is that

• urlencode encodes according to application/x-www-form-urlencoded (space is encoded with +) while
• rawurlencode encodes according to the plain Percent-Encoding (space is encoded with %20).

In my case I faced this error, after deleting the venv for the perticular project and it showing error for each fields so I tried by changing the BROWSER(Chrome to Edge), And actually it worked..

In my opinion, using the 'free' tier of the service should not be powering a production or customer facing application. While the above solutions work against the Dyno idling, think thoroughly about what you're doing.

If nothing else, use a cron job to ping your site, and disable the check for known low-use periods (ie, overnight) to ensure Heroku doesn't do away with the free tier for everyone else.

Before actually answering your question:

Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.

In your case, to make use of REST principles, you should probably have:

http://ip:5000/users
http://ip:5000/users/<user_id>

Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:

GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id> 

So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.

Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
    if request.method == 'GET':
        """return the information for <user_id>"""
        .
        .
        .
    if request.method == 'POST':
        """modify/update the information for <user_id>"""
        # you can use <user_id>, which is a str but could
        # changed to be int or whatever you want, along
        # with your lxml knowledge to make the required
        # changes
        data = request.form # a multidict containing POST data
        .
        .
        .
    if request.method == 'DELETE':
        """delete user with ID <user_id>"""
        .
        .
        .
    else:
        # POST Error 405 Method Not Allowed
        .
        .
        .

There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.

Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

Marc Gravell's answer is very complete, but I thought I'd add something about this from the user's point of view, as well...

The main difference, from a user's perspective, is that, when you use IQueryable<T> (with a provider that supports things correctly), you can save a lot of resources.

For example, if you're working against a remote database, with many ORM systems, you have the option of fetching data from a table in two ways, one which returns IEnumerable<T>, and one which returns an IQueryable<T>. Say, for example, you have a Products table, and you want to get all of the products whose cost is >$25.

If you do:

 IEnumerable<Product> products = myORM.GetProducts();
 var productsOver25 = products.Where(p => p.Cost >= 25.00);

What happens here, is the database loads all of the products, and passes them across the wire to your program. Your program then filters the data. In essence, the database does a SELECT * FROM Products, and returns EVERY product to you.

With the right IQueryable<T> provider, on the other hand, you can do:

 IQueryable<Product> products = myORM.GetQueryableProducts();
 var productsOver25 = products.Where(p => p.Cost >= 25.00);

The code looks the same, but the difference here is that the SQL executed will be SELECT * FROM Products WHERE Cost >= 25.

From your POV as a developer, this looks the same. However, from a performance standpoint, you may only return 2 records across the network instead of 20,000....

Basically ? [ for left multiple indent and ? ] right multiple indent.

For TR keyboard you can left multiple indent with ? ? 8 and right multiple indent with ? ? 9.Because both 8 and 9 are ALT characters of the these nums.Or if you have a keyboard which has [ or ] characters are belong to ALT(?) property so you can use ? ? KEYBOARD CHARACTER

You can use Trim if you want to remove from start and end.

string stringWithoutNewLine = "\n\nHello\n\n".Trim();
