In my case, after endlessly shutting down the IDE, cleaning, trying to build, etc., the issue was a "untitled folder" inside my "res" folder that I probably added there by mistake.

I wish those kind of errors would be output by Eclipse, the way the Ant script did:

[null] invalid resource directory name: /Users/gubatron/workspace.android/my-project/res/untitled folder

scp is best for one file.
OR a combination of tar & compression for smaller data sets like source code trees with small resources (ie: images, sqlite etc).

• media folders (40 GB)
• database backups (28 GB)
• mp3 libraries (100 GB)

It becomes impractical to build a zip/tar.gz file to transfer with scp at this point do to the physical limits of the hosted server.

As an exercise, you can do some gymnastics like piping tar into ssh and redirecting the results into a remote file. (saving the need to build a swap or temporary clone aka zip or tar.gz)

However,

rsync simplify's this process and allows you to transfer data without consuming any additional disc space.

Also,

Continuous (cron?) updates use minimal changes vs full cloned copies speed up large data migrations over time.

tl;dr
scp == small scale (with room to build compressed files on the same drive)
rsync == large scale (with the necessity to backup large data and no room left)

Use the .str()-method:

Manages the contents of the underlying string object.

1) Returns a copy of the underlying string as if by calling rdbuf()->str().

2) Replaces the contents of the underlying string as if by calling rdbuf()->str(new_str)...

Notes

The copy of the underlying string returned by str is a temporary object that will be destructed at the end of the expression, so directly calling c_str() on the result of str() (for example in auto *ptr = out.str().c_str();) results in a dangling pointer...

You can use date function to format it by using the code below:

echo date("g:i a", strtotime("13:30:30 UTC"));

output: 1:30 pm

The above solutions are great for the scenario where you have a small number of Counters. If you have a big list of them though, something like this is much nicer:

from collections import Counter

A = Counter({'a':1, 'b':2, 'c':3})
B = Counter({'b':3, 'c':4, 'd':5}) 
C = Counter({'a': 5, 'e':3})
list_of_counts = [A, B, C]

total = sum(list_of_counts, Counter())

print(total)
# Counter({'c': 7, 'a': 6, 'b': 5, 'd': 5, 'e': 3})

The above solution is essentially summing the Counters by:

total = Counter()
for count in list_of_counts:
    total += count
print(total)
# Counter({'c': 7, 'a': 6, 'b': 5, 'd': 5, 'e': 3})

This does the same thing but I think it always helps to see what it is effectively doing underneath.

As one of the answers above says: " then drag the formula fill handle." This KEY feature is not mentioned in MS's explanation, nor in others here. I spent over an hour trying to follow the various instructions, to no avail. This is because you have to click and hold near the bottom of the cell just right (and at least on my computer that is not at all easy) so that a sort of "handle" appears. Once you're luck enough to get that, then carefully slide ["drag"] your cursor down to the lowermost of the cells you want to be multiplied by the constant. The products should show up in each cell as you move down. Just dragging down will give you only the answer in the first cell and a lot of white space.

    public void printReflectionClassNames(){
    StringBuffer buffer = new StringBuffer();
    Class clazz= buffer.getClass();
    System.out.println("Reflection on String Buffer Class");
    System.out.println("Name: "+clazz.getName());
    System.out.println("Simple Name: "+clazz.getSimpleName());
    System.out.println("Canonical Name: "+clazz.getCanonicalName());
    System.out.println("Type Name: "+clazz.getTypeName());
}

outputs:

Simple Name: StringBuffer
Canonical Name: java.lang.StringBuffer
Type Name: java.lang.StringBuffer

Global makes the variable "Global"

def out():
    global x
    x = 1
    print(x)
    return


out()

print (x)

This makes 'x' act like a normal variable outside the function. If you took the global out then it would give an error since it cannot print a variable inside a function.

def out():
     # Taking out the global will give you an error since the variable x is no longer 'global' or in other words: accessible for other commands
    x = 1
    print(x)
    return


out()

print (x)

System.Environment has WorkingSet- a 64-bit signed integer containing the number of bytes of physical memory mapped to the process context.

If you want a lot of details there is System.Diagnostics.PerformanceCounter, but it will be a bit more effort to setup.

If you are using Visual Studio, you can also left-click on the project in Solution Explorer and change the Windows Authentication property to Enabled in the Properties window.

$(document).ready(function() {
    var $startAt = null;

    $(document.body).live("mousemove", function(e) {
        if ($startAt) {
            $("#someDiv").offset({
                top: e.pageY,
                left: $("#someDiv").position().left-$startAt+e.pageX
            });
            $startAt = e.pageX; 
        }
    });

    $("#someDiv").live("mousedown", function (e) {$startAt = e.pageX;});
    $(document.body).live("mouseup", function (e) {$startAt = null;});
});

I understand that this question is old, but there is a good solution for it in HTML5. You can wrap it all in a <figure></figure> tag. The code would look something like this:

<div id="wrapper">
<figure>

<a href="mailto:[email protected]">
<img id="fblogo" border="0" alt="Mail" src="http://olympiahaacht.be/wp- 
content/uploads/2012/07/email-icon-e1343123697991.jpg"/>
</a>

<a href="https://www.facebook.com/OlympiaHaacht" target="_blank">
<img id="fblogo" border="0" alt="Facebook" src="http://olympiahaacht.be/wp- 
content/uploads/2012/04/FacebookButtonRevised-e1334605872360.jpg"/>
</a>

</figure>
</div>

and the CSS:

#wrapper{
 text-align:center;
}

FETCH_HEAD is a short-lived ref, to keep track of what has just been fetched from the remote repository. git pull first invokes git fetch, in normal cases fetching a branch from the remote; FETCH_HEAD points to the tip of this branch (it stores the SHA1 of the commit, just as branches do). git pull then invokes git merge, merging FETCH_HEAD into the current branch.

The result is exactly what you'd expect: the commit at the tip of the appropriate remote branch is merged into the commit at the tip of your current branch.

This is a bit like doing git fetch without arguments (or git remote update), updating all your remote branches, then running git merge origin/<branch>, but using FETCH_HEAD internally instead to refer to whatever single ref was fetched, instead of needing to name things.

If you're looking to do this XCode 5+, I found this is the easiest method:

Install ios-sim:

npm install -g ios-sim

Then simply execute:

ios-sim launch ./mySample.app --devicetypeid com.apple.CoreSimulator.SimDeviceType.iPhone-6

In which you can switch up your device type. Simple, fast, and it actually works.

If your directory structure is like this,

site
  application
         controller
                folder_1
                   first_controller.php
                   second_controller.php
                folder_2
                   first_controller.php
                   second_controller.php

And when you are going to redirect it in same controller in which you are working then just write the following code.

 $this->load->helper('url');
    if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
    {
         redirect('same_controller/method', 'refresh');
    }

And if you want to redirect to another control then use the following code.

$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
     redirect('folder_name/any_controller_name/method', 'refresh');
}

If you want unified way to handle both uncaught errors and unhandled promise rejections you may have a look on uncaught library.

EDIT

<script type="text/javascript" src=".../uncaught/lib/index.js"></script>

<script type="text/javascript">
    uncaught.start();
    uncaught.addListener(function (error) {
        console.log('Uncaught error or rejection: ', error.message);
    });
</script>

It listens window.unhandledrejection in addition to window.onerror.

These two CSS properties can be used to hide the scrollbars:

overflow-y: hidden; // hide vertical
overflow-x: hidden; // hide horizontal

git for-each-ref --format='%(refname:short) <- %(upstream:short)' refs/heads

will show a line for each local branch. A tracking branch will look like:

master <- origin/master

A non-tracking one will look like:

test <- 

The updated or deleted values are stored in DELETED. we can get it by the below method in trigger

Full example,

CREATE TRIGGER PRODUCT_UPDATE ON PRODUCTS
FOR UPDATE 
AS
BEGIN
DECLARE @PRODUCT_NAME_OLD VARCHAR(100)
DECLARE @PRODUCT_NAME_NEW VARCHAR(100)

SELECT @PRODUCT_NAME_OLD = product_name from DELETED
SELECT @PRODUCT_NAME_NEW = product_name from INSERTED

END

Just to add on [This line perfectly work in Asp.net& find web-control Fields in jason Eg:<%Fieldname%>]

 data: "{LocationName:'" + document.getElementById('<%=txtLocationName.ClientID%>').value + "',AreaID:'" + document.getElementById('<%=DropDownArea.ClientID%>').value + "'}",

I did this and it works great

<?php if ( has_post_thumbnail() ) { ?>
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?></a>
<?php } ?>

PYTHONPATH is an environment variable whose value is a list of directories. Once set, it is used by Python to search for imported modules, along with other std. and 3rd-party library directories listed in Python's "sys.path".

As any other environment variables, you can either export it in shell or in ~/.bashrc, see here. You can query os.environ['PYTHONPATH'] for its value in Python as shown below:

$ python3 -c "import os, sys; print(os.environ['PYTHONPATH']); print(sys.path) if 'PYTHONPATH' in sorted(os.environ) else print('PYTHONPATH is not defined')"

IF defined in shell as

$ export PYTHONPATH=$HOME/Documents/DjangoTutorial/mysite

THEN result =>

/home/Documents/DjangoTutorial/mysite
['', '/home/Documents/DjangoTutorial/mysite', '/usr/local/lib/python37.zip', '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']

ELSE result =>

PYTHONPATH is not defined

To set PYTHONPATH to multiple paths, see here.

Note that one can add or delete a search path via sys.path.insert(), del or remove() at run-time, but NOT through os.environ[]. Example:

>>> os.environ['PYTHONPATH']="$HOME/Documents/DjangoTutorial/mysite"
>>> 'PYTHONPATH' in sorted(os.environ)
True
>>> sys.path // but Not there
['', '/usr/local/lib/python37.zip', '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']

>>> sys.path.insert(0,os.environ['PYTHONPATH'])
>>> sys.path // It's there
['$HOME/Documents/DjangoTutorial/mysite', '', '/usr/local/lib/python37.zip', '/usr/local/lib/python3.7', '/usr/local/lib/python3.7/lib-dynload', '/usr/local/lib/python3.7/site-packages']
>>> 

In summary, PYTHONPATH is one way of specifying the Python search path(s) for imported modules in sys.path. You can also apply list operations directly to sys.path without the aid of PYTHONPATH.

In my case, I accidentally put component name (Home) as the first argument to connect function while it was supposed to be at the end. duh.

This one -surely- gave me the error:

export default connect(Home)(mapStateToProps, mapDispatchToProps)

But this one worked -surely- fine:

export default connect(mapStateToProps, mapDispatchToProps)(Home)

sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf

sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

sudo service apache2 restart

Run above commands issue will be resolved.

x = [];
for( var i in myObj ) {
    x[i] = myObj[i];
}

the following code worked fine for me. kindly check other setting in your web config

 <system.webServer>
     <defaultDocument>
            <files>
                <clear />               
                <add value="Login.aspx"/>
            </files>
        </defaultDocument>
    </system.webServer>

For ex .. add class:

btn-lg - LARGE

btn-sm - SMALL

btn-xs - Very small

<button type=button class="btn btn-default btn-lg">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default">
<span class="glyphicon glyphicon-star" aria-hidden=true></span>Star
</button>

 <button type=button class="btn btn-default btn-sm">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button> 

<button type=button class="btn btn-default btn-xs">
<span class="glyphicon glyphicon-star" aria-hidden=true></span> Star
</button>

How about something like this for shorter text?

It could even work for longer text if you did something with a loop, repeating the characters with JavaScript. Anyway, the result is something like this:

p.char {_x000D_
  position: relative;_x000D_
  display: inline-block;_x000D_
  font-size: 60px;_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
p.char:before {_x000D_
  position: absolute;_x000D_
  content: attr(char);_x000D_
  width: 50%;_x000D_
  overflow: hidden;_x000D_
  color: black;_x000D_
}

<p class="char" char="S">S</p>_x000D_
<p class="char" char="t">t</p>_x000D_
<p class="char" char="a">a</p>_x000D_

The following tables are store WooCommerce products database :

• wp_posts -

  The core of the WordPress data is the posts. It is stored a post_type like product or variable_product.

• wp_postmeta-

  Each post features information called the meta data and it is stored in the wp_postmeta. Some plugins may add their own information to this table like WooCommerce plugin store product_id of product in wp_postmeta table.

Product categories, subcategories stored in this table :

• wp_terms
• wp_termmeta
• wp_term_taxonomy
• wp_term_relationships
• wp_woocommerce_termmeta

following Query Return a list of product categories

SELECT wp_terms.* 
    FROM wp_terms 
    LEFT JOIN wp_term_taxonomy ON wp_terms.term_id = wp_term_taxonomy.term_id
    WHERE wp_term_taxonomy.taxonomy = 'product_cat';

If you are using git, this searches all of the tracked files:

git grep -L "foo"

and you can search in a subset of tracked files if you have ** subdirectory globbing turned on (shopt -s globstar in .bashrc, see this):

git grep -L "foo" -- **/*.cpp

Go to "Window -> Preferences -> General -> C/C++ -> Code analysis" and disable "Syntax and Semantics Errors -> Abstract class cannot be instantiated"

Try this:

// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
//byte[] byteArray = Encoding.ASCII.GetBytes(contents);
MemoryStream stream = new MemoryStream(byteArray);

and

// convert stream to string
StreamReader reader = new StreamReader(stream);
string text = reader.ReadToEnd();

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

Something along the lines of (using JSTL):

<p>Selected Values:
<ul>
  <c:forEach items="${paramValues['select2']}" var="selectedValue">
    <li><c:out value="${selectedValue}" /></li>
  </c:forEach>
</ul>
</p>

setMargins() sets the INNER margins of the TextView, not the layout-margins. Is that what you want to do? This two different margins can be quite complicated.

If you want to set the layout margins, change the LayoutParams of the TextView (textview.getLayoutParams(), then change the parameters on the returned LayoutParams object).

You don't need to change anything on your LinearLayout.

As Dave Webb mentions, the Android Developer Blog has an article that covers this.

I spoke with someone at Google to get some additional clarification on a few items. Here's what I discovered that's NOT mentioned in the aforementioned blog post:

• ANDROID_ID is the preferred solution. ANDROID_ID is perfectly reliable on versions of Android <=2.1 or >=2.3. Only 2.2 has the problems mentioned in the post.
• Several devices by several manufacturers are affected by the ANDROID_ID bug in 2.2.
• As far as I've been able to determine, all affected devices have the same ANDROID_ID, which is 9774d56d682e549c. Which is also the same device id reported by the emulator, btw.
• Google believes that OEMs have patched the issue for many or most of their devices, but I was able to verify that as of the beginning of April 2011, at least, it's still quite easy to find devices that have the broken ANDROID_ID.

Based on Google's recommendations, I implemented a class that will generate a unique UUID for each device, using ANDROID_ID as the seed where appropriate, falling back on TelephonyManager.getDeviceId() as necessary, and if that fails, resorting to a randomly generated unique UUID that is persisted across app restarts (but not app re-installations).

import android.content.Context;

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

The C standard (actually C99, I'm not up to date) says:

Alphabetic escape sequences representing nongraphic characters in the execution character set are intended to produce actions on display devices as follows:

\b (backspace) Moves the active position to the previous position on the current line. [...]

\t (horizontal tab) Moves the active position to the next horizontal tabulation position on the current line. [...]

Both just move the active position, neither are supposed to write any character on or over another character. To overwrite with a space you could try: puts("foo\b \tbar"); but note that on some display devices - say a daisy wheel printer - the o will show the transparent space.

I ran into the same. Saw an example using this: https://github.com/flesler/jquery.scrollTo

I use it as follows:

$('#arrow_back').click(function () {
    $.scrollTo('#features_1', 1000, { easing: 'easeInOutExpo', offset: 0, 'axis': 'y' }); 
});

Clean solution. Works for me!

It's also important to realize that simply moving the program break pointer around with brk and sbrk doesn't actually allocate the memory, it just sets up the address space. On Linux, for example, the memory will be "backed" by actual physical pages when that address range is accessed, which will result in a page fault, and will eventually lead to the kernel calling into the page allocator to get a backing page.

Another option is using eval. This is only suitable if the strings are trusted. The first script can echo the variable assignments:

echo "VAR=myvalue"

Then:

eval $(./first.sh) ./second.sh

This approach is of particular interest when the second script you want to set environment variables for is not in bash and you also don't want to export the variables, perhaps because they are sensitive and you don't want them to persist.

Solution for Laravel 7

1. Install font-awesome library.

npm install font-awesome --save

2. After installing the library. Open the following file and paste given code

<you_project_location>/resources/sass/app.scss

@import "~font-awesome/scss/font-awesome";

3. Open the following file and paste given code

<you_project_location>/webpack.mix.js

mix.setResourceRoot("../");

4. As per your environment execute command.

npm run dev

or

npm run production

There is no need to copy and paste the font folder to the public folder, all will be handled automatically.

Here is a slightly modified version of elegant implementation from the book "JavaScript: The Good Parts".

NOTE: This version of by is stable. It preserves the order of the first sort while performing the next chained sort.

I have added isAscending parameter to it. Also converted it to ES6 standards and "newer" good parts as recommended by the author.

You can sort ascending as well as descending and chain sort by multiple properties.

const by = function (name, minor, isAscending=true) {_x000D_
    const reverseMutliplier = isAscending ? 1 : -1;_x000D_
    return function (o, p) {_x000D_
        let a, b;_x000D_
        let result;_x000D_
        if (o && p && typeof o === "object" && typeof p === "object") {_x000D_
            a = o[name];_x000D_
            b = p[name];_x000D_
            if (a === b) {_x000D_
                return typeof minor === 'function' ? minor(o, p) : 0;_x000D_
            }_x000D_
            if (typeof a === typeof b) {_x000D_
                result = a < b ? -1 : 1;_x000D_
            } else {_x000D_
                result = typeof a < typeof b ? -1 : 1;_x000D_
            }_x000D_
            return result * reverseMutliplier;_x000D_
        } else {_x000D_
            throw {_x000D_
                name: "Error",_x000D_
                message: "Expected an object when sorting by " + name_x000D_
            };_x000D_
        }_x000D_
    };_x000D_

Analytics! This avoids having to access the table twice:

SELECT DISTINCT
       FIRST_VALUE(date_col)  OVER (ORDER BY value_col DESC, date_col ASC),
       FIRST_VALUE(value_col) OVER (ORDER BY value_col DESC, date_col ASC)
FROM   mytable;

I have tried your code in above code don't use [preferences.load(configFile);] statement and it will work.here is running sample code

public static void main(String[]s)
{

    Logger log = Logger.getLogger("MyClass");
    try {
    FileInputStream fis =  new FileInputStream("p.properties");
    LogManager.getLogManager().readConfiguration(fis);
    log.setLevel(Level.FINE);
    log.addHandler(new java.util.logging.ConsoleHandler());
    log.setUseParentHandlers(false);

    log.info("starting myApp");
    fis.close();

    } 
    catch(IOException e) {
    e.printStackTrace();
    }
}

I've need to move a UIView in swift 4 when keyboard opens and closes. and all of the answers couldn't help me. because height of keyboard changes when emojis open. so my code is :

@objc func keyboardWillShow(sender: NSNotification) {

    if let keyboardFrame: NSValue = sender.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue {

        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height

        if(self.oldHeight == keyboardHeight){
            self.sendingView.frame.origin.y -= keyboardHeight
            self.oldHeight = keyboardHeight
        }
        else{
            self.sendingView.frame.origin.y += self.oldHeight
            self.sendingView.frame.origin.y -= keyboardHeight
            self.oldHeight = keyboardHeight
        }
    }
}

@objc func keyboardWillHide(sender: NSNotification) {

    if let keyboardFrame: NSValue = sender.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue {

        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height

        self.sendingView.frame.origin.y += keyboardHeight

    }
}

and in viewDidLoad() :

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name:NSNotification.Name.UIKeyboardWillShow, object: nil);
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name:NSNotification.Name.UIKeyboardWillHide, object: nil);

self.oldHeight = CGFloat() and defines as field at the top of class.

Using a commit's SHA1 key, you could do the following:

• First, find the commit you want for a specific file:

  git log -n <# commits> <file-name>

  This, based on your <# commits>, will generate a list of commits for a specific file.

  TIP: if you aren't sure what commit you are looking for, a good way to find out is using the following command: git diff <commit-SHA1>..HEAD <file-name>. This command will show the difference between the current version of a commit, and a previous version of a commit for a specific file.

  NOTE: a commit's SHA1 key is formatted in the git log -n's list as:

commit <SHA1 id>

• Second, checkout the desired version:

  If you have found the desired commit/version you want, simply use the command: git checkout <desired-SHA1> <file-name>

  This will place the version of the file you specified in the staging area. To take it out of the staging area simply use the command: reset HEAD <file-name>

To revert back to where the remote repository is pointed to, simply use the command: git checkout HEAD <file-name>

NUnit loads the unit tests in a seperate AppDomain, and I assume the entry point is not being called (probably not needed), hence the entry assembly is null.

I have crawled through a lot of blog posts including a few Stack Overflow pots, and I already had everything in place what these posts suggested (see below) when I got this error.

1. My app pool is running under ApplicationPoolIdentity
2. Load user Profile was set to True in Process Model section
3. IIS AppPool\DefaultAppPool has full permissions on temp ASP.NET files folder

Finally I found some clues in the below mentioned blog post. It looks like there is heap contention with the same user account. So I changed the app pool identity to LocalSystem, for the app which is failing with this error - and my app started working fine.

See blog post C# compiler or Visual Basic .Net compilers fail with error code -1073741502 when generating assemblies for your ASP.net site.

Note: LocalSystem account will not have much permissions. In my case my application does not need any special permissions. So I was fine. If your application needs special permissions try configuring a custom account.

If you are working on a machine where it doesn't have permissions to all the files and moreover you have two versions such as default 2.7 & latest 3.6 then while running the command use the python version with the command. If the latest python is installed with sudo then run the command with sudo.

exp:

sudo python3.6 manage.py runserver

Week Start & End Date From Date For Power BI Dax Formula

WeekStartDate = [DateColumn] - (WEEKDAY([DateColumn])-1)
WeekEndDate = [DateColumn] + (7-WEEKDAY([DateColumn]))

Expanding on some other answers, this is what I do:

Setup the repo: git clone --mirror user@server:/url-to-repo.git

Then when you want to refresh the backup: git remote update from the clone location.

This backs up all branches and tags, including new ones that get added later, although it's worth noting that branches that get deleted do not get deleted from the clone (which for a backup may be a good thing).

This is atomic so doesn't have the problems that a simple copy would.

See http://www.garron.me/en/bits/backup-git-bare-repo.html

I hit an issue where following an Update, SVN showed a folder as being conflicted. Strangely, this was only visible through the command line - TortoiseSVN thought it was all fine.

#>svn st
!       my_dir
!       my_dir\sub_dir

svn cleanup, svn revert, svn update and svn resolve were all unsuccessful at fixing this.

I eventually solved the problem as follows:

• Look in the .svn directory for "sub_dir"
• Use RC -> Properties to uncheck the 'read only' flag on the entries file
• Open the entries file and delete the line "unfinished ..." and the corresponding checksum
• Save, and re-enable the read-only flag
• Repeat for the my_dir directory

Following that, everything was fine.

Note I didn't have any local changes, so I don't know if you'd be at risk if you did. I didn't use the delete / update method suggested by others - I got into this state by trying that on the my_dir/sub_dir/sub_sub_dir directory (which started with the same symptoms) - so I didn't want to risk making things worse again!

Not quite on-topic, but maybe helpful if someone comes across this post as I did.

This error was thrown by another app that I'm sharing my app's file to (using Intent.FLAG_GRANT_READ_URI_PERMISSION)

Turns out, the File Uri has to be provided via FileProvider class as shown here.

I did it like this (temporarily turning on delayed expansion):

      ...
sqlcmd -b -S %COMPUTERNAME% -E -d %DBNAME% -Q "SELECT label from document WHERE label = '%DOCID%';" -h-1 -o Result.txt
      if errorlevel 1 goto INVALID
    :: Read SQL result and trim trailing whitespace
    SET /P ITEM=<Result.txt
    @echo ITEM is %ITEM%.
    setlocal enabledelayedexpansion
    for /l %%a in (1,1,100) do if "!ITEM:~-1!"==" " set ITEM=!ITEM:~0,-1!
    setlocal disabledelayedexpansion
    @echo Var ITEM=%ITEM% now has trailing spaces trimmed.
....

The max size for a column of type NVARCHAR(MAX) is 2 GByte of storage.

Since NVARCHAR uses 2 bytes per character, that's approx. 1 billion characters.

Leo Tolstoj's War and Peace is a 1'440 page book, containing about 600'000 words - so that might be 6 million characters - well rounded up. So you could stick about 166 copies of the entire War and Peace book into each NVARCHAR(MAX) column.

Is that enough space for your needs? :-)

Short answer: using as.data.frame.matrix(mytable), as @Victor Van Hee suggested.

Long answer: as.data.frame(mytable) may not work on contingency tables generated by table() function, even if is.matrix(your_table) returns TRUE. It will still melt you table into the factor1 factor2 factori counts format.

Example:

> freq_t = table(cyl = mtcars$cyl, gear = mtcars$gear)

> freq_t
   gear
cyl  3  4  5
  4  1  8  2
  6  2  4  1
  8 12  0  2

> is.matrix(freq_t)
[1] TRUE

> as.data.frame(freq_t)
  cyl gear Freq
1   4    3    1
2   6    3    2
3   8    3   12
4   4    4    8
5   6    4    4
6   8    4    0
7   4    5    2
8   6    5    1
9   8    5    2
> as.data.frame.matrix(freq_t)
   3 4 5
4  1 8 2
6  2 4 1
8 12 0 2

Consider using namespaces:

(function() {
    var local_var = 'foo';
    global_var = 'bar'; // this.global_var and window.global_var also work

    function local_function() {}
    global_function = function() {};
})();

Both local_function and global_function have access to all local and global variables.

Edit: Another common pattern:

var ns = (function() {
    // local stuff
    function foo() {}
    function bar() {}
    function baz() {} // this one stays invisible

    // stuff visible in namespace object
    return {
        foo : foo,
        bar : bar
    };
})();

The returned properties can now be accessed via the namespace object, e.g. ns.foo, while still retaining access to local definitions.

The simple way to use XMLHttpRequest with pure JavaScript. You can set custom header but it's optional used based on requirement.

1. Using POST Method:

window.onload = function(){
    var request = new XMLHttpRequest();
    var params = "UID=CORS&name=CORS";

    request.onreadystatechange = function() {
        if (this.readyState == 4 && this.status == 200) {
            console.log(this.responseText);
        }
    };

    request.open('POST', 'https://www.example.com/api/createUser', true);
    request.setRequestHeader('api-key', 'your-api-key');
    request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    request.send(params);
}

You can send params using POST method.

2. Using GET Method:

Please run below example and will get an JSON response.

window.onload = function(){_x000D_
    var request = new XMLHttpRequest();_x000D_
_x000D_
    request.onreadystatechange = function() {_x000D_
        if (this.readyState == 4 && this.status == 200) {_x000D_
            console.log(this.responseText);_x000D_
        }_x000D_
    };_x000D_
_x000D_
    request.open('GET', 'https://jsonplaceholder.typicode.com/users/1');_x000D_
    request.send();_x000D_
}

You can use JavaScript's encodeURIComponent:

encodeURIComponent('select * from table where i()')

giving

'select%20*%20from%20table%20where%20i()'

The obvious thing to do is just convert the search term to lowercase:

if (in_array(strtolower($word), $array)) { 
  ...

of course if there are uppercase letters in the array you'll need to do this first:

$search_array = array_map('strtolower', $array);

and search that. There's no point in doing strtolower on the whole array with every search.

Searching arrays however is linear. If you have a large array or you're going to do this a lot, it would be better to put the search terms in key of the array as this will be much faster access:

$search_array = array_combine(array_map('strtolower', $a), $a);

then

if ($search_array[strtolower($word)]) {

The only issue here is that array keys must be unique so if you have a collision (eg "One" and "one") you will lose all but one.

Note that with | char, you can get a warning with your IDE, for exemple I get warning with the last version of IntelliJ, So the best solution it's to use this syntax:

th:text="${'static_content - ' + you_variable}"

assertNotNull asserts that the object is not null. If it is null the test fails, so you want that.

Just as a addition. You can find the Catalina Paths in

->RUN->RUN CONFIGURATIONS->APACHE TOMCAT->ARGUMENTS

In the VM Arguments the Paths are listed and changeable

Component is the template(view) + a class (Typescript code) containing some logic for the view + metadata(to tell angular about from where to get data it needs to display the template).

Modules basically group the related components, services together so that you can have chunks of functionality which can then run independently. For example, an app can have modules for features, for grouping components for a particular feature of your app, such as a dashboard, which you can simply grab and use inside another application.

I'd rather use more convenient itemSelect event. With this event you can use org.primefaces.event.SelectEvent objects in your listener.

<p:selectOneMenu ...>
    <p:ajax event="itemSelect" 
        update="messages"
        listener="#{beanMB.onItemSelectedListener}"/>
</p:selectOneMenu>

With such listener:

public void onItemSelectedListener(SelectEvent event){
    MyItem selectedItem = (MyItem) event.getObject();
    //do something with selected value
}

This one finally gave me the answer I was looking for. It lets you retrieve all the names and phone numbers of the contacts on the phone.

package com.test;

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;

public class TestContacts extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
                              null, null, null, null);
        if (cur != null && cur.getCount() > 0) {
            while (cur.moveToNext()) {

                if (Integer.parseInt.equals(cur.getString(cur.getColumnIndex(
                            ContactsContract.Contacts.HAS_PHONE_NUMBER)))) {
                    String id = cur.getString(cur.getColumnIndex(
                                ContactsContract.Contacts._ID));
                    String name = cur.getString(cur.getColumnIndex(
                                ContactsContract.Contacts.DISPLAY_NAME));
                    Cursor pCur = cr.query(
                                           ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            null,
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                    + " = ?", new String[] { id }, null);
                    int i = 0;
                    int pCount = pCur.getCount();
                    String[] phoneNum = new String[pCount];
                    String[] phoneType = new String[pCount];
                    while (pCur != null && pCur.moveToNext()) {
                        phoneNum[i] = pCur.getString(pCur.getColumnIndex(
                        ContactsContract.CommonDataKinds.Phone.NUMBER));
                        phoneType[i] = pCur.getString(pCur.getColumnIndex(
                                ContactsContract.CommonDataKinds.Phone.TYPE));
                        i++;
                    }
                }

            }

        }

    }
}

The profiler data is written to a collection in your DB, not to file. See http://docs.mongodb.org/manual/tutorial/manage-the-database-profiler/

I would recommend using 10gen's MMS service, and feed development profiler data there, where you can filter and sort it in the UI.

And in my case, it turned out that I didn't have IIS enabled in Control Panel under Windows Features. Reference Image, since SO won't let me upload

If inserting 'too much data' fails due to the max_allowed_packet setting of the database server, the following warning is raised:

SQLSTATE[08S01]: Communication link failure: 1153 Got a packet bigger than 
'max_allowed_packet' bytes

If this warning is catched as exception (due to the set error handler), the database connection is (probably) lost but the application doesn't know about this (failing inserts can have several causes). The next query in line, which can be as simple as:

SELECT 1 FROM DUAL

Will then fail with the error this SO-question started:

Error while sending QUERY packet. PID=18486

Simple test script to reproduce my explanation, try it with and without the error handler to see the difference in impact:

set_error_handler(function($errno, $errstr, $errfile, $errline, array $errcontext) {
    // error was suppressed with the @-operator
    if (0 === error_reporting()) {
        return false;
    }

    throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});

try
{
    // $oDb is instance of PDO
    var_dump($oDb->query('SELECT 1 FROM DUAL'));

    $oStatement = $oDb->prepare('INSERT INTO `test` (`id`, `message`) VALUES (NULL, :message);');
    $oStatement->bindParam(':message', $largetext, PDO::PARAM_STR);
    var_dump($oStatement->execute());
}
catch(Exception $e)
{
    $e->getMessage();
}
var_dump($oDb->query('SELECT 2 FROM DUAL'));

As Drake states this could be done with FileReader. However, what I present here is a functional version. Take in consideration that the big problem with doing this with JavaScript is to reset the input file. Well, this restricts to only JPG (for other formats you will have to change the mime type and the magic number):

<form id="form-id">
  <input type="file" id="input-id" accept="image/jpeg"/>
</form>

<script type="text/javascript">
    $(function(){
        $("#input-id").on('change', function(event) {
            var file = event.target.files[0];
            if(file.size>=2*1024*1024) {
                alert("JPG images of maximum 2MB");
                $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                return;
            }

            if(!file.type.match('image/jp.*')) {
                alert("only JPG images");
                $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                return;
            }

            var fileReader = new FileReader();
            fileReader.onload = function(e) {
                var int32View = new Uint8Array(e.target.result);
                //verify the magic number
                // for JPG is 0xFF 0xD8 0xFF 0xE0 (see https://en.wikipedia.org/wiki/List_of_file_signatures)
                if(int32View.length>4 && int32View[0]==0xFF && int32View[1]==0xD8 && int32View[2]==0xFF && int32View[3]==0xE0) {
                    alert("ok!");
                } else {
                    alert("only valid JPG images");
                    $("#form-id").get(0).reset(); //the tricky part is to "empty" the input file here I reset the form.
                    return;
                }
            };
            fileReader.readAsArrayBuffer(file);
        });
    });
</script>

Take in consideration that this was tested on latest versions of Firefox and Chrome, and on IExplore 10.

For a complete list of mime types see Wikipedia.

For a complete list of magic number see Wikipedia.

<select v-model="challan.warehouse_id">
<option value="">Select Warehouse</option>
<option v-for="warehouse in warehouses" v-bind:value="warehouse.id"  >
   {{ warehouse.name }}
</option>

Here "challan.warehouse_id" come from "challan" object you get from:

editChallan: function() {
    let that = this;
    axios.post('/api/challan_list/get_challan_data', {
    challan_id: that.challan_id
 })
 .then(function (response) {
    that.challan = response.data;
 })
 .catch(function (error) {
    that.errors = error;
  }); 
 }

You can use like this(Though the random number generator logic is not upto the mark)

public class WorkSheet {
    HashMap<String,ArrayList<Integer>> map = new HashMap<String,ArrayList<Integer>>();

public static void main(String args[]) {
    WorkSheet test = new WorkSheet();
    test.inputData("mango", 5);
    test.inputData("apple", 2);
    test.inputData("grapes", 2);
    test.inputData("peach", 3);
    test.displayData();

}
public void displayData(){
    for (Entry<String, ArrayList<Integer>> entry : map.entrySet()) {
        System.out.print(entry.getKey()+" | ");
        for(int fruitNo : entry.getValue()){
            System.out.print(fruitNo+" ");
        }
        System.out.println();
    }
}
public void inputData(String name ,int number) {
    Random rndData = new Random();
    ArrayList<Integer> fruit = new ArrayList<Integer>();
    for(int i=0 ; i<number ; i++){
        fruit.add(rndData.nextInt(10));
    }
    map.put(name, fruit);
}
}

OUTPUT

grapes | 7 5 
apple | 9 5 
peach | 5 5 8 
mango | 4 7 1 5 5 

From the answer here, spark.sql.shuffle.partitions configures the number of partitions that are used when shuffling data for joins or aggregations.

spark.default.parallelism is the default number of partitions in RDDs returned by transformations like join, reduceByKey, and parallelize when not set explicitly by the user. Note that spark.default.parallelism seems to only be working for raw RDD and is ignored when working with dataframes.

If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions) (don't forget to assign it to a new val) in your code.

To change the settings in your code you can simply do:

sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")

Alternatively, you can make the change when submitting the job to a cluster with spark-submit:

./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300

float b = (float)Math.ceil(a); or float b = (float)Math.round(a);

Depending on whether you meant "round to the nearest whole number" (round) or "round up" (ceil).

Beware of loss of precision in converting a double to a float, but that shouldn't be an issue here.

1.Install angular-animate

2.Add the animation effect to the class ng-enter for page entering animation and the class ng-leave for page exiting animation

for reference: this page has a free resource on angular view transition https://e21code.herokuapp.com/angularjs-page-transition/

To get all eventListeners on a page printed alongside their elements

Array.from(document.querySelectorAll("*")).forEach(e => {
    const ev = getEventListeners(e)
    if (Object.keys(ev).length !== 0) console.log(e, ev)
})

When it is on server side, use web services - maybe RESTful with JSON.

• create a web service (for example with Tomcat)
• call its URL from JavaScript (for example with JQuery or dojo)

When Java code is in applet you can use JavaScript bridge. The bridge between the Java and JavaScript programming languages, known informally as LiveConnect, is implemented in Java plugin. Formerly Mozilla-specific LiveConnect functionality, such as the ability to call static Java methods, instantiate new Java objects and reference third-party packages from JavaScript, is now available in all browsers.

Below is example from documentation. Look at methodReturningString.

Java code:

public class MethodInvocation extends Applet {
    public void noArgMethod() { ... }
    public void someMethod(String arg) { ... }
    public void someMethod(int arg) { ... }
    public int  methodReturningInt() { return 5; }
    public String methodReturningString() { return "Hello"; }
    public OtherClass methodReturningObject() { return new OtherClass(); }
}

public class OtherClass {
    public void anotherMethod();
}

Web page and JavaScript code:

<applet id="app"
        archive="examples.jar"
        code="MethodInvocation" ...>
</applet>
<script language="javascript">
    app.noArgMethod();
    app.someMethod("Hello");
    app.someMethod(5);
    var five = app.methodReturningInt();
    var hello = app.methodReturningString();
    app.methodReturningObject().anotherMethod();
</script>

How about

a["abc"] = [1, 2]

This will result in:

>>> a
{'abc': [1, 2]}

Is that what you were looking for?

IMHO, it is more efficient to drop the table and re-create it. And yes, you can use "IF EXISTS" in this case.

What everyone seems to miss is that the semi-colons in JavaScript are not statement terminators but statement separators. It's a subtle difference, but it is important to the way the parser is programmed. Treat them like what they are and you will find leaving them out will feel much more natural.

I've programmed in other languages where the semi-colon is a statement separator and also optional as the parser does 'semi-colon insertion' on newlines where it does not break the grammar. So I was not unfamiliar with it when I found it in JavaScript.

I don't like noise in a language (which is one reason I'm bad at Perl) and semi-colons are noise in JavaScript. So I omit them.

I refer few writings.

• How to get total RAM size of a device?

This getMemorySize() method is returned MemorySize that has total and free memory size.
I don't believe this code perfectly.
This code is testing on LG G3 cat.6 (v5.0.1)

    private MemorySize getMemorySize() {
        final Pattern PATTERN = Pattern.compile("([a-zA-Z]+):\\s*(\\d+)");

        MemorySize result = new MemorySize();
        String line;
        try {
            RandomAccessFile reader = new RandomAccessFile("/proc/meminfo", "r");
            while ((line = reader.readLine()) != null) {
                Matcher m = PATTERN.matcher(line);
                if (m.find()) {
                    String name = m.group(1);
                    String size = m.group(2);

                    if (name.equalsIgnoreCase("MemTotal")) {
                        result.total = Long.parseLong(size);
                    } else if (name.equalsIgnoreCase("MemFree") || name.equalsIgnoreCase("Buffers") ||
                            name.equalsIgnoreCase("Cached") || name.equalsIgnoreCase("SwapFree")) {
                        result.free += Long.parseLong(size);
                    }
                }
            }
            reader.close();

            result.total *= 1024;
            result.free *= 1024;
        } catch (IOException e) {
            e.printStackTrace();
        }

        return result;
    }

    private static class MemorySize {
        public long total = 0;
        public long free = 0;
    }

I know that Pattern.compile() is expensive cost so You may move its code to class member.

To avoid an input with only spaces, use: "[a-zA-Z0-9]+[a-zA-Z0-9 ]+".

eg: abc | abc aBc | abc 123 AbC 938234

To ensure, for example, that a first AND last name are entered, use a slight variation like

"[a-zA-Z]+[ ][a-zA-Z]+"

eg: abc def

Basically it's designing your cell, The cellforrowatindexpath is called for each cell and the cell number is found by indexpath.row and section number by indexpath.section . Here you can use a label, button or textfied image anything that you want which are updated for all rows in the table. Answer for second question In cell for row at index path use an if statement

In Objective C

-(UITableViewCell *)tableView:(UITableView *)tableView  cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

 NSString *CellIdentifier = @"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

  if(tableView == firstTableView)
  {
      //code for first table view 
      [cell.contentView addSubview: someView];
  }

  if(tableview == secondTableView)
  {
      //code for secondTableView 
      [cell.contentView addSubview: someView];
  }
  return cell;
}

In Swift 3.0

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell 
{
  let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!

  if(tableView == firstTableView)   {
     //code for first table view 
  }

  if(tableview == secondTableView)      {
     //code for secondTableView 
  }

  return cell
}

you can run flutter clean command

1) If you are using (PHP 5 >= 5.3.6) you can use SplFileInfo::getExtension — Gets the file extension

Example code

<?php

$info = new SplFileInfo('test.png');
var_dump($info->getExtension());

$info = new SplFileInfo('test.tar.gz');
var_dump($info->getExtension());

?>

This will output

string(3) "png"
string(2) "gz"

2) Another way of getting the extension if you are using (PHP 4 >= 4.0.3, PHP 5) is pathinfo

Example code

<?php

$ext = pathinfo('test.png', PATHINFO_EXTENSION);
var_dump($ext);

$ext = pathinfo('test.tar.gz', PATHINFO_EXTENSION);
var_dump($ext);

?>

This will output

string(3) "png"
string(2) "gz"

// EDIT: removed a bracket

I believe you are trying to compare two strings representing values, the function you are looking for is:

int atoi(const char *nptr);

or

long int strtol(const char *nptr, char **endptr, int base);

these functions will allow you to convert a string to an int/long int:

int val = strtol("555", NULL, 10);

and compare it to another value.

int main (int argc, char *argv[])
{
    long int val = 0;
    if (argc < 2)
    {
        fprintf(stderr, "Usage: %s number\n", argv[0]);
        exit(EXIT_FAILURE);
    }

    val = strtol(argv[1], NULL, 10);
    printf("%d is %s than 555\n", val, val > 555 ? "bigger" : "smaller");

    return 0;
}

What you are missing, as idljarn already mentioned in a comment is that if you are overriding a function from a base class, then you cannot possibly mark it as non-virtual:

struct base {
   virtual void f();
};
struct derived : base {
   void f() final;       // virtual as it overrides base::f
};
struct mostderived : derived {
   //void f();           // error: cannot override!
};

I'm not sure how to do it with curl, but libwww-perl installs the GET alias.

The 1.3 docs offer a very simple solution: KeyedTuple._asdict()

def to_array(rows):
    return [r._asdict() for r in rows]

def query():
    data = session.query(Table).all()
    return to_array(data)

I'm not sure it's worth it for me to type this all up from scratch since this article published in A List Apart does a pretty good job explaining it. MDN also has a handy guide for HTML5 forms and validation (covering the API and also the related CSS).

No, you cannot. But you can create a user defined table function.

The device I tested at had wrong time set. So when I tried accessing a page with a certificate that would run out soon it would deny access because the device though the certificate had expired. To fix, set proper time on the device!

Check your manifest,Open the file with .xml extension and then all your activities are listed your first activity should have this code enclosed in its tags

<intent-filter>
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

or there is another way u can choose from configuration which is drop down list on the left side of run button choose from App from it Hope it will help!!

Some time you can solve problem through MySQL Administrator wizard. In

Startup variables > Advanced >

and set Def. char Set:utf8

Maybe this config need restart MySQL.

curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.19.1 Basic ECC zlib/1.2.3 libidn/1.18 libssh2/1.4.2

You are using a very old version of curl. My guess is that you run into the bug described 6 years ago. Fix is to update your curl.

You can use below code .

 iframe {background:url(../images/loader.gif) center center no-repeat; height: 100%;}

First, coming up with correct abstractions is always a key. key to readability, maintainability, and extendability.

Here, quite obvious candidate is an ISO8601DateTime. There are at least two implementations: first one is a parsed datetime from a string, and the second one is tomorrow. Hence, there are two classes that can be used, and their combination results in (almost) desired outcome:

new Tomorrow(new FromISO8601('2013-01-22'));

Both objects are an ISO8601 datetime, so their textual representation is not exactly what you need. So the final stroke is to make them take a date-form:

new Date(
    new Tomorrow(
        new FromISO8601('2013-01-22')
    )
);

Since you need a textual representation, not just an object, you invoke a value() method.

For more about this approach, take a look at this post.

You can simply use the data-interval attribute of the carousel class.

It's default value is set to data-interval="3000" i.e 3seconds.

All you need to do is set it to your desired requirements.

http://docs.jquery.com/Events/jQuery.Event

Try with event.target

Contains the DOM element that issued the event. This can be the element that registered for the event or a child of it.

Basically, no. That is an http header, so it is reasonable to cast to HttpWebRequest and set the .Referer (as you indicate in the question):

HttpWebRequest req = ...
req.Referer = "your url";

The question asks which characters are allowed in GET parameters without encoding or escaping them.

According to RFC3986 (general URL syntax) and RFC7230, section 2.7.1 (HTTP/S URL syntax) the only characters you need to percent-encode are those outside of the query set, see the definition below.

However, there are additional specifications like HTML5, Web forms, and the obsolete Indexed search, W3C recommendation. Those documents add a special meaning to some characters notably, to symbols like = & + ;.

Other answers here suggest that most of the reserved characters should be encoded, including "/" "?". That's not correct. In fact, RFC3986, section 3.4 advises against percent-encoding "/" "?" characters.

it is sometimes better for usability to avoid percent- encoding those characters.

RFC3986 defines query component as:

query       = *( pchar / "/" / "?" )
pchar       = unreserved / pct-encoded / sub-delims / ":" / "@"
pct-encoded = "%" HEXDIG HEXDIG
sub-delims  = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="
unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~" 

A percent-encoding mechanism is used to represent a data octet in a component when that octet's corresponding character is outside the allowed set or is being used as a delimiter of, or within, the component.

The conclusion is that XYZ part should encode:

special: # % = & ;
Space
sub-delims
out of query set: [ ]
non ASCII encodable characters

Unless special symbols = & ; are key=value separators.

Encoding other characters is allowed but not necessary.

There are two possible reasons for that problem:

1. did not install aclocal.
   solution:install libtool

   • For ubuntu: sudo apt-get install libtool
   • For centos: sudo yum install libtool

2. the path to LIBTOOL.m4 is error.
   solution:

   1. use aclocal --print-ac-dir to check current path to aclocal.(It's usually should be "/usr/share/aclocal" or "/usr/share/aclocal")
   2. Then check if there are *.m4 files.
   3. If not, cp corresponding *.m4 files to this path.( Maybe cp /usr/share/aclocal/*.m4 /usr/local/share/aclocal/ or cp /usr/local/share/aclocal/*.m4 /usr/share/aclocal/)

Hope it helps

There isn't a single answer for this.

Encryption will always consume more CPU. This can be offloaded to dedicated hardware in many cases, and the cost will vary by algorithm selected. 3des is more expensive than AES, for example. Some algorithms are more expensive for the encrypter than the decryptor. Some have the opposite cost.

More expensive than the bulk crypto is handshake cost. New connections will consume much more CPU. This can be reduced with session resumption, at the cost of keeping old session secrets around until they expire. This means that small requests from a client that doesn't come back for more are the most expensive.

For cross internet traffic you may not notice this cost in your data rate, because the bandwidth available is too low. But you will certainly notice it in CPU usage on a busy server.

Here's one way:

Stream myStream = null;
OpenFileDialog theDialog = new OpenFileDialog();
theDialog.Title = "Open Text File";
theDialog.Filter = "TXT files|*.txt";
theDialog.InitialDirectory = @"C:\";
if (theDialog.ShowDialog() == DialogResult.OK)
{
    try
    {
        if ((myStream = theDialog.OpenFile()) != null)
        {
            using (myStream)
            {
                // Insert code to read the stream here.
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
    }
}

EDIT Here's another way more suited to your needs:

private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
    OpenFileDialog theDialog = new OpenFileDialog();
    theDialog.Title = "Open Text File";
    theDialog.Filter = "TXT files|*.txt";
    theDialog.InitialDirectory = @"C:\";
    if (theDialog.ShowDialog() == DialogResult.OK)
    {
        string filename = theDialog.FileName;

        string[] filelines = File.ReadAllLines(filename);

        List<Employee> employeeList = new List<Employee>();
        int linesPerEmployee = 4;
        int currEmployeeLine = 0;
        //parse line by line into instance of employee class
        Employee employee = new Employee();
        for (int a = 0; a < filelines.Length; a++)
        {

            //check if to move to next employee
            if (a != 0 && a % linesPerEmployee == 0)
            {
                employeeList.Add(employee);
                employee = new Employee();
                currEmployeeLine = 1;
            }

            else
            {
                currEmployeeLine++;
            }
            switch (currEmployeeLine)
            {
                case 1:
                    employee.EmployeeNum = Convert.ToInt32(filelines[a].Trim());
                    break;
                case 2:
                    employee.Name = filelines[a].Trim();
                    break;
                case 3:
                    employee.Address = filelines[a].Trim();
                    break;
                case 4:
                    string[] splitLines = filelines[a].Split(' ');

                    employee.Wage = Convert.ToDouble(splitLines[0].Trim());
                    employee.Hours = Convert.ToDouble(splitLines[1].Trim());
                    break;


            }

        }
        //Test to see if it works
        foreach (Employee emp in employeeList)
        {
            MessageBox.Show(emp.EmployeeNum + Environment.NewLine +
                emp.Name + Environment.NewLine +
                emp.Address + Environment.NewLine +
                emp.Wage + Environment.NewLine +
                emp.Hours + Environment.NewLine);
        }
    }
}

Your query is very close. You should be able to use the following which includes the subject in the final select list:

select u.name, u.subject, u.marks
from student s
unpivot
(
  marks
  for subject in (Maths, Science, English)
) u;

There's another way that works if you don't mind only targeting newer browsers. Just add the CSS

pointer-events: none;

to any children of the div you want to capture the click. Here's the support tables

http://caniuse.com/#feat=pointer-events

Do this if you are using GoDaddy, I'm using Lets Encrypt SSL if you want you can get it.

Here is the code - The code is in asp.net core 2.0 but should work in above versions.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using MailKit.Net.Smtp;
using MimeKit;

namespace UnityAssets.Website.Services
{
    public class EmailSender : IEmailSender
    {
        public async Task SendEmailAsync(string toEmailAddress, string subject, string htmlMessage)
        {
            var email = new MimeMessage();
            email.From.Add(new MailboxAddress("Application Name", "[email protected]"));
            email.To.Add(new MailboxAddress(toEmailAddress, toEmailAddress));
            email.Subject = subject;

            var body = new BodyBuilder
            {
                HtmlBody = htmlMessage
            };

            email.Body = body.ToMessageBody();

            using (var client = new SmtpClient())
            {
                //provider specific settings
                await client.ConnectAsync("smtp.gmail.com", 465, true).ConfigureAwait(false);
                await client.AuthenticateAsync("[email protected]", "sketchunity").ConfigureAwait(false);

                await client.SendAsync(email).ConfigureAwait(false);
                await client.DisconnectAsync(true).ConfigureAwait(false);
            }
        }
    }
}

Sometimes, the previously installed version is cached.

~$ pip install pillow==5.2.0

It returns the followings:
Requirement already satisfied: pillow==5.2.0 in /home/ubuntu/anaconda3/lib/python3.6/site-packages (5.2.0)

We can use --no-cache-dir together with -I to overwrite this

~$ pip install --no-cache-dir -I pillow==5.2.0

What worked for me was this-- On Ubuntu

1. Ctrl+F1
2. ps -e
3. kill -9 for process ids of eclipse, java and adb

I have virtually no knowledge of C#, but I suspect that either switch was simply taken as it occurs in other languages without thinking about making it more general or the developer decided that extending it was not worth it.

Strictly speaking you are absolutely right that there is no reason to put these restrictions on it. One might suspect that the reason is that for the allowed cases the implementation is very efficient (as suggested by Brian Ensink (44921)), but I doubt the implementation is very efficient (w.r.t. if-statements) if I use integers and some random cases (e.g. 345, -4574 and 1234203). And in any case, what is the harm in allowing it for everything (or at least more) and saying that it is only efficient for specific cases (such as (almost) consecutive numbers).

I can, however, imagine that one might want to exclude types because of reasons such as the one given by lomaxx (44918).

Edit: @Henk (44970): If Strings are maximally shared, strings with equal content will be pointers to the same memory location as well. Then, if you can make sure that the strings used in the cases are stored consecutively in memory, you can very efficiently implement the switch (i.e. with execution in the order of 2 compares, an addition and two jumps).

This can be done by using the java.net.URI class to construct a new instance using the parts from an existing one, this should ensure it conforms to URI syntax.

The query part will either be null or an existing string, so you can decide to append another parameter with & or start a new query.

public class StackOverflow26177749 {

    public static URI appendUri(String uri, String appendQuery) throws URISyntaxException {
        URI oldUri = new URI(uri);

        String newQuery = oldUri.getQuery();
        if (newQuery == null) {
            newQuery = appendQuery;
        } else {
            newQuery += "&" + appendQuery;  
        }

        return new URI(oldUri.getScheme(), oldUri.getAuthority(),
                oldUri.getPath(), newQuery, oldUri.getFragment());
    }

    public static void main(String[] args) throws Exception {
        System.out.println(appendUri("http://example.com", "name=John"));
        System.out.println(appendUri("http://example.com#fragment", "name=John"));
        System.out.println(appendUri("http://[email protected]", "name=John"));
        System.out.println(appendUri("http://[email protected]#fragment", "name=John"));
    }
}

Shorter alternative

public static URI appendUri(String uri, String appendQuery) throws URISyntaxException {
    URI oldUri = new URI(uri);
    return new URI(oldUri.getScheme(), oldUri.getAuthority(), oldUri.getPath(),
            oldUri.getQuery() == null ? appendQuery : oldUri.getQuery() + "&" + appendQuery, oldUri.getFragment());
}

Output

http://example.com?name=John
http://example.com?name=John#fragment
http://[email protected]&name=John
http://[email protected]&name=John#fragment

A predicate in T is a delegate that takes in a T and returns a bool. List<T>.RemoveAll will remove all elements in a list where calling the predicate returns true. The easiest way to supply a simple predicate is usually a lambda expression, but you can also use anonymous methods or actual methods.

{
    List<Vehicle> vehicles;
    // Using a lambda
    vehicles.RemoveAll(vehicle => vehicle.EnquiryID == 123);
    // Using an equivalent anonymous method
    vehicles.RemoveAll(delegate(Vehicle vehicle)
    {
        return vehicle.EnquiryID == 123;
    });
    // Using an equivalent actual method
    vehicles.RemoveAll(VehiclePredicate);
}

private static bool VehiclePredicate(Vehicle vehicle)
{
    return vehicle.EnquiryID == 123;
}

This will also work fine :

int ans = 0;
while(num){
 ans += (num &1);
 num = num >>1;
}    
return ans;

For Python 2.x:

':'.join(x.encode('hex') for x in 'Hello World!')

The code above will not work with Python 3.x, for 3.x, the code below will work:

':'.join(hex(ord(x))[2:] for x in 'Hello World!')

I realize this is an old question, but I use a much simpler way. Typically I just grab the list that I need, either by query or copying an existing list or whatever, then remove the duplicates. We will assume for this answer that your list is already in column C, row 4, as per the original question. This method works for whatever size list you have and you can select header yes or no.

Dim rng as range
Range("C4").Select
Set rng = Range(Selection, Selection.End(xlDown))
rng.RemoveDuplicates Columns:=1, Header:=xlYes

Long term, you will be able to use the ResizeObserver.

new ResizeObserver(callback).observe(element);

Unfortunately it is not currently supported by default in many browsers.

In the mean time, you can use function like the following. Since, the majority of element size changes will come from the window resizing or from changing something in the DOM. You can listen to window resizing with the window's resize event and you can listen to DOM changes using MutationObserver.

Here's an example of a function that will call you back when the size of the provided element changes as a result of either of those events:

var onResize = function(element, callback) {
  if (!onResize.watchedElementData) {
    // First time we are called, create a list of watched elements
    // and hook up the event listeners.
    onResize.watchedElementData = [];

    var checkForChanges = function() {
      onResize.watchedElementData.forEach(function(data) {
        if (data.element.offsetWidth !== data.offsetWidth ||
            data.element.offsetHeight !== data.offsetHeight) {
          data.offsetWidth = data.element.offsetWidth;
          data.offsetHeight = data.element.offsetHeight;
          data.callback();
        }
      });
    };

    // Listen to the window's size changes
    window.addEventListener('resize', checkForChanges);

    // Listen to changes on the elements in the page that affect layout 
    var observer = new MutationObserver(checkForChanges);
    observer.observe(document.body, { 
      attributes: true,
      childList: true,
      characterData: true,
      subtree: true 
    });
  }

  // Save the element we are watching
  onResize.watchedElementData.push({
    element: element,
    offsetWidth: element.offsetWidth,
    offsetHeight: element.offsetHeight,
    callback: callback
  });
};

Note that the file:/// scheme does not work on the compact framework, at least it doesn't with 5.0.

You will need to use the following:

string appDir = Path.GetDirectoryName(
    Assembly.GetExecutingAssembly().GetName().CodeBase);
webBrowser1.Url = new Uri(Path.Combine(appDir, @"Documentation\index.html"));

For more performance: A simple change is observing that after n = 3n+1, n will be even, so you can divide by 2 immediately. And n won't be 1, so you don't need to test for it. So you could save a few if statements and write:

while (n % 2 == 0) n /= 2;
if (n > 1) for (;;) {
    n = (3*n + 1) / 2;
    if (n % 2 == 0) {
        do n /= 2; while (n % 2 == 0);
        if (n == 1) break;
    }
}

Here's a big win: If you look at the lowest 8 bits of n, all the steps until you divided by 2 eight times are completely determined by those eight bits. For example, if the last eight bits are 0x01, that is in binary your number is ???? 0000 0001 then the next steps are:

3n+1 -> ???? 0000 0100
/ 2  -> ???? ?000 0010
/ 2  -> ???? ??00 0001
3n+1 -> ???? ??00 0100
/ 2  -> ???? ???0 0010
/ 2  -> ???? ???? 0001
3n+1 -> ???? ???? 0100
/ 2  -> ???? ???? ?010
/ 2  -> ???? ???? ??01
3n+1 -> ???? ???? ??00
/ 2  -> ???? ???? ???0
/ 2  -> ???? ???? ????

So all these steps can be predicted, and 256k + 1 is replaced with 81k + 1. Something similar will happen for all combinations. So you can make a loop with a big switch statement:

k = n / 256;
m = n % 256;

switch (m) {
    case 0: n = 1 * k + 0; break;
    case 1: n = 81 * k + 1; break; 
    case 2: n = 81 * k + 1; break; 
    ...
    case 155: n = 729 * k + 425; break;
    ...
}

Run the loop until n = 128, because at that point n could become 1 with fewer than eight divisions by 2, and doing eight or more steps at a time would make you miss the point where you reach 1 for the first time. Then continue the "normal" loop - or have a table prepared that tells you how many more steps are need to reach 1.

PS. I strongly suspect Peter Cordes' suggestion would make it even faster. There will be no conditional branches at all except one, and that one will be predicted correctly except when the loop actually ends. So the code would be something like

static const unsigned int multipliers [256] = { ... }
static const unsigned int adders [256] = { ... }

while (n > 128) {
    size_t lastBits = n % 256;
    n = (n >> 8) * multipliers [lastBits] + adders [lastBits];
}

In practice, you would measure whether processing the last 9, 10, 11, 12 bits of n at a time would be faster. For each bit, the number of entries in the table would double, and I excect a slowdown when the tables don't fit into L1 cache anymore.

PPS. If you need the number of operations: In each iteration we do exactly eight divisions by two, and a variable number of (3n + 1) operations, so an obvious method to count the operations would be another array. But we can actually calculate the number of steps (based on number of iterations of the loop).

We could redefine the problem slightly: Replace n with (3n + 1) / 2 if odd, and replace n with n / 2 if even. Then every iteration will do exactly 8 steps, but you could consider that cheating :-) So assume there were r operations n <- 3n+1 and s operations n <- n/2. The result will be quite exactly n' = n * 3^r / 2^s, because n <- 3n+1 means n <- 3n * (1 + 1/3n). Taking the logarithm we find r = (s + log2 (n' / n)) / log2 (3).

If we do the loop until n = 1,000,000 and have a precomputed table how many iterations are needed from any start point n = 1,000,000 then calculating r as above, rounded to the nearest integer, will give the right result unless s is truly large.

Map<String, Integer> map = new HashMap<>();
map.put("test1", 1);
map.put("test2", 2);

Map<String, Integer> map2 = new HashMap<>();
map.forEach(map2::put);

System.out.println("map: " + map);
System.out.println("map2: " + map2);
// Output:
// map:  {test2=2, test1=1}
// map2: {test2=2, test1=1}

You can use the forEach method to do what you want.

What you're doing there is:

map.forEach(new BiConsumer<String, Integer>() {
    @Override
    public void accept(String s, Integer integer) {
        map2.put(s, integer);     
    }
});

Which we can simplify into a lambda:

map.forEach((s, integer) ->  map2.put(s, integer));

And because we're just calling an existing method we can use a method reference, which gives us:

map.forEach(map2::put);

In my case, I was getting this error despite registering an existing instance for the interface in question.

Turned out, it was because I was using Unity in WebForms by way of the Unity.WebForms Nuget package, and I had specified a Hierarchical Lifetime manager for the dependency I was providing an instance for, yet a Transient lifetime manager for a subsequent type that depended on the previous type - not usually an issue - but with Unity.WebForms, the lifetime managers work a little differently... your injected types seem to require a Hierarchical lifetime manager, but a new container is still created for every web request (because of the architecture of web forms I guess) as explained excellently in this post.

Anyway, I resolved it by simply not specifying a lifetime manager for the types/instances when registering them.

i.e.

container.RegisterInstance<IMapper>(MappingConfig.GetMapper(), new HierarchicalLifetimeManager());    
container.RegisterType<IUserContext, UserContext>(new TransientLifetimeManager());

becomes

container.RegisterInstance<IMapper>(MappingConfig.GetMapper());
container.RegisterType<IUserContext, UserContext>();

So that IMapper can be resolved successfully here:

public class UserContext : BaseContext, IUserContext
{
    public UserContext(IMapper _mapper) : base(_mapper)
    {

    }
    ...
}

document.getElementById("address_box").value = 
(title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4);

If you don't want to use str.lower(), you can use a regular expression:

import re

if re.search('mandy', 'Mandy Pande', re.IGNORECASE):
    # Is True

Remove the quotes surrounding 0 and it will work.

in my case, i had the same problem while i try any git -- commands (eg git status) using windows cmd. so what i do is after installing git for window https://windows.github.com/ in the environmental variables, add the class path of the git on the "PATH" varaiable. usually the git will installed on C:/user/"username"/appdata/local/git/bin add this on the PATH in the environmental variable

and one more thing on the cmd go to your git repository or cd to where your clone are on your window usually they will be stored on the documents under github

cd Document/Github/yourproject

after that you can have any git commands

After reading many questions on stackoverflow I found out that my CPU does not support Virtualization. I have to upgrade to the cpu which supports Virtualization in order to install Intel X 86 Emulator accelerator(Haxm Installer)

You just need to override the method for back button. You can leave the method empty if you want so that nothing will happen when you press back button. Please have a look at the code below:

@Override
public void onBackPressed() 
{
   // Your Code Here. Leave empty if you want nothing to happen on back press.
}

I use a very simple combination of CSS and jQuery which displays the email address correctly to the user and also works when the anchor is clicked or hovered:

HTML:

<a href="mailto:[email protected]" id="lnkMail">moc.elpmaxe@em</a>

CSS:

#lnkMail {
    unicode-bidi: bidi-override;
    direction: rtl;
}

jQuery:

$('#lnkMail').hover(function(){
    // here you can use whatever replace you want
    var newHref = $(this).attr('href').replace('spam', 'com');
    $(this).attr('href', newHref);
});

Here is a working example.

Had this problem too.. the package was installed on Python 3.8.0 but VS Code was running my script using an older version (3.4)

fix in terminal:

py .py

Make sure you're installing the package on the right Python Version

I just tested your snippet, and their is no double spacing line here. The end-of-line are \r\n, so what i would check in your case is:

1. your editor is reading correctly DOS file
2. no \n exist in values of your rows dict.

(Note that even by putting a value with \n, DictWriter automaticly quote the value.)

First off, Xvfb doesn't read configuration from xorg.conf. Xvfb is a variant of the KDrive X servers and like all members of that family gets its configuration from the command line.

It is true that XRandR and Xinerama are mutually exclusive, but in the case of Xvfb there's no Xinerama in the first place. You can enable the XRandR extension by starting Xvfb using at least the following command line options

Xvfb +extension RANDR [further options]

This website has some nice examples for using spring's RestTemplate. Here is a code example of how it can work to get a simple object:

private static void getEmployees()
{
    final String uri = "http://localhost:8080/springrestexample/employees.xml";

    RestTemplate restTemplate = new RestTemplate();
    String result = restTemplate.getForObject(uri, String.class);

    System.out.println(result);
}

The cause of your problems is that you are trying to do a cross-domain call and it fails.

If you're doing localhost development you can make cross-domain calls - I do it all the time.

For Firefox, you have to enable it in your config settings

signed.applets.codebase_principal_support = true

Then add something like this to your XHR open code:

  if (isLocalHost()){
    if (typeof(netscape) != 'undefined' && typeof(netscape.security) != 'undefined'){
      netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
    }
  }

For IE, if I remember right, all you have to do is enable the browser's Security setting under "Miscellaneous → Access data sources across domains" to get it to work with ActiveX XHRs.

IE8 and above also added cross-domain capabilities to the native XmlHttpRequest objects, but I haven't played with those yet.

This issue occur when you migrate your android project build in windows to any unix operating system (Linux). So you need to run the below command in your project directory to convert dos Line Break to Unix Line Break.

find . -type f -print0 | xargs -0 dos2unix

If you dont have dos2unix installed. Install it using

In CentOs/Fedora

yum install dos2unix

In Ubuntu and other distributions

sudo apt install dos2unix

The accepted answer covers it all, so I'll just give another example of a shortcut that I use, for the record.

Add it to your etc/vim/vimrc (or ~/.vimrc):

• cnoremap w!! execute 'silent! write !sudo tee % >/dev/null' <bar> edit!

Where:

• cnoremap: tells vim that the following shortcut is to be associated in the command line.
• w!!: the shortcut itself.
• execute '...': a command that execute the following string.
• silent!: run it silently
• write !sudo tee % >/dev/null: the OP question, added a redirection of messages to NULL to make a clean command
• <bar> edit!: this trick is the cherry of the cake: it calls also the edit command to reload the buffer and then avoid messages such as the buffer has changed. <bar> is how to write the pipe symbol to separate two commands here.

Hope it helps. See also for other problems:

• SuperUser: force vim to write a file

try this it's very easy to use and tested on IE and Safari and FF and worked fine and beside no need for many div around it just add id and it will work fine, after you link you Js and Css files. FaceScroll Custom scrollbar

hope it help's

Edit Step 1: Add the below script to the section of your page:

        $('#demo2').alternateScroll({ 'vertical-bar-class': 'styled-v-bar', 'hide-bars': false });  
    })

You can use xxd:

$cat hex.txt
68 65 6c 6c 6f
$cat hex.txt | xxd -r -p
hello

I would just do it by reference if it's only a few return values but for more complex types you can also just do it like this :

static struct SomeReturnType {int a,b,c; string str;} SomeFunction()
{
  return {1,2,3,string("hello world")}; // make sure you return values in the right order!
}

use "static" to limit the scope of the return type to this compilation unit if it's only meant to be a temporary return type.

 SomeReturnType st = SomeFunction();
 cout << "a "   << st.a << endl;
 cout << "b "   << st.b << endl;
 cout << "c "   << st.c << endl;
 cout << "str " << st.str << endl;

This is definitely not the prettiest way to do it but it will work.

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

You need to use the various Bootstrap 4 centering methods...

• Use text-center for inline elements.
• Use justify-content-center for flexbox elements (ie; form-inline)

https://codeply.com/go/Am5LvvjTxC

Also, to offset the column, the col-sm-* must be contained within a .row, and the .row must be in a container...

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

try: android:editable="false" or android:inputType="none"

Assuming you want to replace the newlines with something so that something like this:

the quick brown fox\r\n
jumped over the lazy dog\r\n

doesn't end up like this:

the quick brown foxjumped over the lazy dog

I'd do something like this:

string[] SplitIntoChunks(string text, int size)
{
    string[] chunk = new string[(text.Length / size) + 1];
    int chunkIdx = 0;
    for (int offset = 0; offset < text.Length; offset += size)
    {
        chunk[chunkIdx++] = text.Substring(offset, size);
    }
    return chunk;
}    

string[] GetComments()
{
    var cmtTb = GridView1.Rows[rowIndex].FindControl("txtComments") as TextBox; 
    if (cmtTb == null)
    {
        return new string[] {};
    }

    // I assume you don't want to run the text of the two lines together?
    var text = cmtTb.Text.Replace(Environment.Newline, " ");
    return SplitIntoChunks(text, 50);    
}

I apologize if the syntax isn't perfect; I'm not on a machine with C# available right now.

You must create them under strings.xml

<string name="close">Close</string>    

You must replace and reference like this

android:text="@string/close"/>

Do not use @strings even though the XML file says strings.xml or else it will not work.

In the keypress event handler:

e.Handled = true;

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

So you cant have the behavior that you want but you can do something that feels like it. You want to be able to do Choice.first.question

what I have done in the past is something like this

class Choice
  belongs_to :user
  belongs_to :answer
  validates_uniqueness_of :answer_id, :scope => [ :question_id, :user_id ]
  ...
  def question
    answer.question
  end
end

this way the you can now call question on Choice

Completely reset?

1. Delete the .git directory locally.

2. Recreate the git repostory:

   $ cd (project-directory)
   $ git init
   $ (add some files)
   $ git add .
   $ git commit -m 'Initial commit'
   

3. Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.

   $ git remote add origin <url>
   $ git push --force --set-upstream origin master
   

Enqueue another css file after the select2.css, and in that css add the following:

.select2-container .select2-selection {
  height: 34px; 
}

i.e. if you want the height of the select box height to be 34px.

I found a simpler solution that requires neither adding element nor a special class. found it there: http://www.sencha.com/forum/archive/index.php/t-141560.html

And converted the code to jquery :

function hideKeyboard(element) {
    element.attr('readonly', 'readonly'); // Force keyboard to hide on input field.
    element.attr('disabled', 'true'); // Force keyboard to hide on textarea field.
    setTimeout(function() {
        element.blur();  //actually close the keyboard
        // Remove readonly attribute after keyboard is hidden.
        element.removeAttr('readonly');
        element.removeAttr('disabled');
    }, 100);
}

You call the function by passing it the input from which the keyboard was opened, or just passing $('input') should also work.

There's a much easier way of doing this. You can assign a Name to your Window or UserControl, and then binding by ElementName.

Window1.xaml

<Window x:Class="QuizBee.Host.Window1"
        x:Name="Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <ListView ItemsSource="{Binding ElementName=Window1, Path=myDictionary}" />
</Window>

Window1.xaml.cs

public partial class Window1:Window
{
    // the property must be public, and it must have a getter & setter
    public Dictionary<string, myClass> myDictionary { get; set; }

    public Window1()
    {
        // define the dictionary items in the constructor
        // do the defining BEFORE the InitializeComponent();

        myDictionary = new Dictionary<string, myClass>()
        {
            {"item 1", new myClass(1)},
            {"item 2", new myClass(2)},
            {"item 3", new myClass(3)},
            {"item 4", new myClass(4)},
            {"item 5", new myClass(5)},
        }; 

        InitializeComponent();
    }
}

You import one dependency, and this dependency is dependent on com.sun.jmx:jmxri:jar:1.2.1 and others, but com.sun.jmx:jmxri:jar:1.2.1 cannot be found in central repository,

so you'd better try to import another version.

Here suppose your dependency may be log4j, and you can try to import log4j:log4j:jar:1.2.13.

scp -r C:/site user@server_ip:path

path is the place, where site will be copied into the remote server

EDIT: As I said in my comment, try pscp, as you want to use scp using PuTTY.

The other option is WinSCP

Use Window.location.href to take the url in javascript. it's a property that will tell you the current URL location of the browser. Setting the property to something different will redirect the page.

if (window.location.href.indexOf("?added-to-cart=555") > -1) {
    alert("found it");
}

Sadly, mod_evasive won't work as expected when used in non-prefork configurations (recent apache setups are mainly MPM)

How about this?

for item in mylist:
    if item in checklist:
        pass
    else:
       # do something
       print item

Depends on what you know about your url and exactly what you're tryinh to do. If you know that it will always end in '.com' (or '.net' or '.org') then

 url=url[:-4]

is the quickest solution. If it's a more general URLs then you're probably better of looking into the urlparse library that comes with python.

If you on the other hand you simply want to remove everything after the final '.' in a string then

url.rsplit('.',1)[0]

will work. Or if you want just want everything up to the first '.' then try

url.split('.',1)[0]

I know this is an old question, but here is my contribution. Instead of all these tricks, you can just simply wrap a function inside another function. Like I have done here:

<div data-bind="click: function(){ f('hello parameter'); }">Click me once</div>
<div data-bind="click: function(){ f('no no parameter'); }">Click me twice</div>

var VM = function(){
   this.f = function(param){
     console.log(param);
   }
}
ko.applyBindings(new VM());

And here is the fiddle

def baseN(num,b,numerals="0123456789abcdefghijklmnopqrstuvwxyz"):
    return ((num == 0) and numerals[0]) or (baseN(num // b, b, numerals).lstrip(numerals[0]) + numerals[num % b])

Please be aware that this may lead to

RuntimeError: maximum recursion depth exceeded in cmp

for very big integers.

In JavaScript, you can assign values to data attributes through Element.dataset.

For example:

avatar.dataset.id = 12345;

Not 96x96, use 64x64 instead. I usually use:

• 16 - status/titlebar button
• 32 - desktop icon
• 48 - folder view
• 64/128 - Additional sizes

256 works as well on XP, however, old resource compilers sometimes complained about "out of memory" errors.

I'm answering this as an reminder, to give point to my comment(s) on "user1949346" answer to this same OP.

So as many already answered: either way is fine. Followed by emphasizes of their own impressions.

Introductory, as also in the previous named comments stated, my opinion is C++ header extensions are proposed to be .h if there is actually no reason against it.

Since the ISO/IEC documents use this notation of header files and no string matching to .hpp even occurs in their language documentations about C++.

But I'm now aiming for an approvable reason WHY either way is ok, and especially why it's not subject of the language it self.

So here we go.

The C++ documentation (I'm actually taking reference from the version N3690) defines that a header has to conform to the following syntax:

2.9 Header names

header-name:
    < h-char-sequence >
    " q-char-sequence "
h-char-sequence:
    h-char
    h-char-sequence h-char
h-char:
    any member of the source character set except new-line and >
q-char-sequence:
    q-char
    q-char-sequence q-char
q-char:
    any member of the source character set except new-line and "

So as we can extract from this part, the header file name may be anything that is valid in the source code, too. Except containing '\n' characters and depending on if it is to be included by <> it is not allowed to contain a >. Or the other way if it is included by ""-include it is not allowed to contain a ".

In other words: if you had a environment supporting filenames like prettyStupidIdea.>, an include like:

#include "prettyStupidIdea.>"

would be valid, but:

#include <prettyStupidIdea.>>

would be invalid. The other way around the same.

And even

#include <<.<>

would be a valid includable header file name.

Even this would conform to C++, it would be a pretty pretty stupid idea, tho.

And that's why .hpp is valid, too.

But it's not an outcome of the committees designing decisions for the language!

So discussing about to use .hpp is same as doing it about .cc, .mm or what ever else I read in other posts on this topic.

I have to admit I have no clue where .hpp came from¹, but I would bet an inventor of some parsing tool, IDE or something else concerned with C++ came to this idea to optimize some internal processes or just to invent some (probably even for them necessarily) new naming conventions.

But it is not part of the language.

And whenever one decides to use it this way. May it be because he likes it most or because some applications of the workflow require it, it never² is a requirement of the language. So whoever says "the pp is because it is used with C++", simply is wrong in regards of the languages definition.

C++ allows anything respecting the previous paragraph. And if there is anything the committee proposed to use, then it is using .h since this is the extension sued in all examples of the ISO document.

Conclusion:

As long you don't see/feel any need of using .h over .hpp or vise versa, you shouldn't bother. Because both would be form a valid header name of same quality in respect to the standard. And therefore anything that REQUIRES you to use .h or .hpp is an additional restriction of the standard which could even be contradicting with other additional restrictions not conform with each other. But as OP doesn't mention any additional language restriction, this is the only correct and approvable answer to the question

"*.h or *.hpp for your class definitions" is:

Both are equally correct and applicable as long as no external restrictions are present.

¹_{From what I know, apparently, it is the boost framework that came up with that .hpp extension.}

²_{Of course I can't say what some future versions will bring with it!}

Basically, if you are developing a client- server application. You may use WCF -> in order to make connection between client and server, WPF -> as client side to present the data.

int random(int min, int max) //range : [min, max]
{
   static bool first = true;
   if (first) 
   {  
      srand( time(NULL) ); //seeding for the first time only!
      first = false;
   }
   return min + rand() % (( max + 1 ) - min);
}

Here is a fairly simple way to get the args and set them as env vars. In this example I will just refer to them as Keys and Values.

Save the following code example as "args.bat". Then call the batch file you saved from a command line. example: arg.bat --x 90 --y 120

I have provided some echo commands to step you through the process. But the end result is that --x will have a value of 90 and --y will have a value of 120(that is if you run the example as specified above ;-) ).

You can then use the 'if defined' conditional statement to determine whether or not to run your code block. So lets say run: "arg.bat --x hello-world" I could then use the statement "IF DEFINED --x echo %--x%" and the results would be "hello-world". It should make more sense if you run the batch.

I can show you how I used it

  function GetDenierValue() {
        var denierid = $("#productDenierid").val() == '' ? 0 : $("#productDenierid").val();
        var param = { 'productDenierid': denierid };
        $.ajax({
            url: "/Admin/ProductComposition/GetDenierValue",
            dataType: "json",
            contentType: "application/json;charset=utf-8",
            type: "POST",
            data: JSON.stringify(param),
            success: function (msg) {
                if (msg != null) {
                    return msg.URL;
                }
            }
        });
    }

I think it is better to use Array.Exists than Array.FindAll.

Here's a variation of Oscar's first version that doesn't use a for-each loop.

for (int i = 0; i < charArray.length; i++) {
    if (charArray[i] == 'q') {
        // do something
        break;
    }
}

You could have a boolean variable that gets set to false before the loop, then make "do something" set the variable to true, which you could test for after the loop. The loop could also be wrapped in a function call then just use 'return true' instead of the break, and add a 'return false' statement after the for loop.

It sounds like you're asking about a function

string Left(string s, int left)

that will return the leftmost left characters of the string s. In that case you can just use String.Substring. You can write this as an extension method:

public static class StringExtensions
{
    public static string Left(this string value, int maxLength)
    {
        if (string.IsNullOrEmpty(value)) return value;
        maxLength = Math.Abs(maxLength);

        return ( value.Length <= maxLength 
               ? value 
               : value.Substring(0, maxLength)
               );
    }
}

and use it like so:

string left = s.Left(number);

For your specific example:

string s = fac.GetCachedValue("Auto Print Clinical Warnings").ToLower() + " ";
string left = s.Substring(0, 1);

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

The colon is a built-in command that does nothing, but returns 0 (success). Thus, it's shorter (and faster) than calling an actual command to do the same thing.

Eclipse recognizes incorrect default webapp directory. Therefore we should set clearly it by maven-war-plugin.

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-war-plugin</artifactId>
      <version>3.0.0</version>
      <configuration>
        <webappDirectory>src/main/webapp</webappDirectory>
      </configuration>
    </plugin>
  </plugins>
</build>

Once saving this setting, the error will never occour if removed it. (I cannot explain why.)

Took me a while to get this working based on some of the answers above, so I thought I'd share it for others to use. I hope it's useful.

'use strict';

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
const db = admin.firestore();

exports.countDocumentsChange = functions.firestore.document('library/{categoryId}/documents/{documentId}').onWrite((change, context) => {

    const categoryId = context.params.categoryId;
    const categoryRef = db.collection('library').doc(categoryId)
    let FieldValue = require('firebase-admin').firestore.FieldValue;

    if (!change.before.exists) {

        // new document created : add one to count
        categoryRef.update({numberOfDocs: FieldValue.increment(1)});
        console.log("%s numberOfDocs incremented by 1", categoryId);

    } else if (change.before.exists && change.after.exists) {

        // updating existing document : Do nothing

    } else if (!change.after.exists) {

        // deleting document : subtract one from count
        categoryRef.update({numberOfDocs: FieldValue.increment(-1)});
        console.log("%s numberOfDocs decremented by 1", categoryId);

    }

    return 0;
});

FileZilla did not work for me, I kept getting this error:

Disconnected: No supported authentication methods available (server sent: publickey)

What did work was the sftp command.

Connect with the EC2 Instance with

sftp -i "path/to/key.pem" [email protected]

Downloading files / dirs

To download path/to/source/file.txt and path/to/source/dir:

lcd ~/Desktop
cd path/to/source
get file.txt
get -r dir

Uploading files / dirs

To upload localpath/to/source/file.txt and ~/localpath/to/source/dir to remotepath/to/dest:

lcd localpath/to/source
cd remotepath/to/dest
put file.txt
put -r dir

You can do it with PhantomJSDriver.

PhantomJSDriver pd = ((PhantomJSDriver) ((WebDriverFacade) getDriver()).getProxiedDriver());
pd.executePhantomJS(
            "this.onResourceRequested = function(request, net) {" +
            "   net.setHeader('header-name', 'header-value')" +
            "};");

Using the request object, you can filter also so the header won't be set for every request.

UPDATE: This is no longer valid for newer Keras versions. Please use argmax() as in the answer from Emilia Apostolova.

The functional API models have just the predict() function which for classification would return the class probabilities. You can then select the most probable classes using the probas_to_classes() utility function. Example:

y_proba = model.predict(x)
y_classes = keras.np_utils.probas_to_classes(y_proba)

This is equivalent to model.predict_classes(x) on the Sequential model.

The reason for this is that the functional API support more general class of tasks where predict_classes() would not make sense.

Doing password checks on client side is unsafe especially when the password is hard coded.

The safest way is password checking on server side, but even then the password should not be transmitted plain text.

Checking the password client side is possible in a "secure way":

• The password needs to be hashed
• The hashed password is used as part of a new url

Say "abc" is your password so your md5 would be "900150983cd24fb0d6963f7d28e17f72" (consider salting!). Now build a url containing the hash (like http://yourdomain.com/90015...f72.html).

Using the following snippet you can do similar things pretty easily, like this:

ajax.get('/test.php', {foo: 'bar'}, function() {});

Here is the snippet:

var ajax = {};
ajax.x = function () {
    if (typeof XMLHttpRequest !== 'undefined') {
        return new XMLHttpRequest();
    }
    var versions = [
        "MSXML2.XmlHttp.6.0",
        "MSXML2.XmlHttp.5.0",
        "MSXML2.XmlHttp.4.0",
        "MSXML2.XmlHttp.3.0",
        "MSXML2.XmlHttp.2.0",
        "Microsoft.XmlHttp"
    ];

    var xhr;
    for (var i = 0; i < versions.length; i++) {
        try {
            xhr = new ActiveXObject(versions[i]);
            break;
        } catch (e) {
        }
    }
    return xhr;
};

ajax.send = function (url, callback, method, data, async) {
    if (async === undefined) {
        async = true;
    }
    var x = ajax.x();
    x.open(method, url, async);
    x.onreadystatechange = function () {
        if (x.readyState == 4) {
            callback(x.responseText)
        }
    };
    if (method == 'POST') {
        x.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
    }
    x.send(data)
};

ajax.get = function (url, data, callback, async) {
    var query = [];
    for (var key in data) {
        query.push(encodeURIComponent(key) + '=' + encodeURIComponent(data[key]));
    }
    ajax.send(url + (query.length ? '?' + query.join('&') : ''), callback, 'GET', null, async)
};

ajax.post = function (url, data, callback, async) {
    var query = [];
    for (var key in data) {
        query.push(encodeURIComponent(key) + '=' + encodeURIComponent(data[key]));
    }
    ajax.send(url, callback, 'POST', query.join('&'), async)
};

By CSS:

.disable{
   cursor: not-allowed;
   pointer-events: none;
}

Them you can add any decoration to that button. For change the status you can use jquery

$("#id").toggleClass('disable');

I've switched from curl to Httpie; the syntax looks like:

http http://myurl HeaderName:value

When executed in the browser, webpack needs to know where you'll host the generated bundle. Thus it is able to request additional chunks (when using code splitting) or referenced files loaded via the file-loader or url-loader respectively.

For example: If you configure your http server to host the generated bundle under /assets/ you should write: publicPath: "/assets/"

The project I'm working on, we do something like this. We use the errorlevel keyword so it kind of looks like:

call myExe.exe
if errorlevel 1 (
  goto build_fail
)

That seems to work for us. Note that you can put in multiple commands in the parens like an echo or whatever. Also note that build_fail is defined as:

:build_fail
echo ********** BUILD FAILURE **********
exit /b 1

Nobody has mentioned the index order to access the elements of the initialized array. My example code will give an illustrative example to it.

#include <iostream>

void PrintArray(int a[3][3])
{
    std::cout << "a11 = " << a[0][0] << "\t\t" << "a12 = " << a[0][1] << "\t\t" << "a13 = " << a[0][2] << std::endl;
    std::cout << "a21 = " << a[1][0] << "\t\t" << "a22 = " << a[1][1] << "\t\t" << "a23 = " << a[1][2] << std::endl;
    std::cout << "a31 = " << a[2][0] << "\t\t" << "a32 = " << a[2][1] << "\t\t" << "a33 = " << a[2][2] << std::endl;
    std::cout << std::endl;
}

int wmain(int argc, wchar_t * argv[])
{
    int a1[3][3] =  {   11,     12,     13,     // The most
                        21,     22,     23,     // basic
                        31,     32,     33  };  // format.

    int a2[][3] =   {   11,     12,     13,     // The first (outer) dimension
                        21,     22,     23,     // may be omitted. The compiler
                        31,     32,     33  };  // will automatically deduce it.

    int a3[3][3] =  {   {11,    12,     13},    // The elements of each
                        {21,    22,     23},    // second (inner) dimension
                        {31,    32,     33} };  // can be grouped together.

    int a4[][3] =   {   {11,    12,     13},    // Again, the first dimension
                        {21,    22,     23},    // can be omitted when the 
                        {31,    32,     33} };  // inner elements are grouped.

    PrintArray(a1);
    PrintArray(a2);
    PrintArray(a3);
    PrintArray(a4);

    // This part shows in which order the elements are stored in the memory.
    int * b = (int *) a1;   // The output is the same for the all four arrays.
    for (int i=0; i<9; i++)
    {
        std::cout << b[i] << '\t';
    }

    return 0;
}

The output is:

If the file includes a line break in the middle of the text neither strip() nor rstrip() will not solve the problem,

strip family are used to trim from the began and the end of the string

replace() is the way to solve your problem

>>> my_name = "Landon\nWO"
>>> print my_name
   Landon
   WO

>>> my_name = my_name.replace('\n','')
>>> print my_name
LandonWO

Pick a Column delimiter

Note: You can pick a Text qualifier that will delimit your text fields, such as quotes.

If you have a field with commas, don't use you use comma as a delimiter, because it does not escape commas. You can pick a column delimiter such as Vertical Bar: | instead of comma, or a tab character. Otherwise, write a query that escapes your commas or delimits your varchar field.

The escape character or text qualifier you need to use depends on your requirements.
