Using name on a select option is not valid.

Other have suggested the data- attribute, an alternative is a lookup table

Here the "this" refers to the select so no need to "find" the option

Not sure if this is really beneficial or why I prefer this style but what I do (in vanilla js) is:

document.querySelector('#selector').toggleAttribute('data-something');

This will add the attribute in all lowercase without a value or remove it if it already exists on the element.

https://developer.mozilla.org/en-US/docs/Web/API/Element/toggleAttribute

This is fairly simple with the callback syntax of attr:

$("#product1 :checkbox").click(function(){
  $(this)
   .closest('tr') // find the parent row
       .find(":input[type='text']") // find text elements in that row
           .attr('disabled',function(idx, oldAttr) {
               return !oldAttr; // invert disabled value
           })
           .toggleClass('disabled') // enable them
       .end() // go back to the row
       .siblings() // get its siblings
           .find(":input[type='text']") // find text elements in those rows
               .attr('disabled',function(idx, oldAttr) {
                   return !oldAttr; // invert disabled value
               })
               .removeClass('disabled'); // disable them
});

If the value is hardcoded in the source of the page using the value attribute then you can

$('#attached_docs :input[value="123"]').remove();

If you want to target elements that have a value of 123, which was set by the user or programmatically then use EDIT works both ways ..

or

$('#attached_docs :input').filter(function(){return this.value=='123'}).remove();

demo http://jsfiddle.net/gaby/RcwXh/2/

You need some form of iteration here, as val (except when called with a function) only works on the first element:

$("input[placeholder]").val($("input[placeholder]").attr("placeholder"));

should be:

$("input[placeholder]").each( function () {
    $(this).val( $(this).attr("placeholder") );
});

or

$("input[placeholder]").val(function() {
    return $(this).attr("placeholder");
});

In my case, this error ocurred while i was using the

implementation 'com.android.support:appcompat-v7:+'
implementation 'com.android.support:design:+'

libraries together with googles

implementation 'com.google.android.material:material-components:+'

library. If this is the case in your project, i highly recommend to fully remove the google material components library from your project.

Without having a href, the click will reload the current page, so you need something like this:

<a href="#" onclick="f1()">jhhghj</a>

Or prevent the scroll like this:

<a href="#" onclick="f1(); return false;">jhhghj</a>

Or return false in your f1 function and:

<a href="#" onclick="return f1();">jhhghj</a>

....or, the unobtrusive way:

<a href="#" id="abc">jhg</a>
<a href="#" id="myLink">jhhghj</a>

<script type="text/javascript">
  document.getElementById("myLink").onclick = function() {
    document.getElementById("abc").href="xyz.php"; 
    return false;
  };
</script>

Mostly disabled attribute doesn't work with the anchor tags from HTML-5 onwards. Hence we have change it to ,let's say 'button' and style it accordingly with appropriate color,border-style etc. That's the most apt solution for any similar issue users are facing in Chrome . Only few elements support 'disabled' attribute: Span , select, option, textarea, input , button.

Dirty checkedness

This concept provides an example where the difference is observable: http://www.w3.org/TR/html5/forms.html#concept-input-checked-dirty

Try it out:

• click the button. Both checkboxes got checked.
• uncheck both checkboxes.
• click the button again. Only the prop checkbox got checked. BANG!

$('button').on('click', function() {_x000D_
  $('#attr').attr('checked', 'checked')_x000D_
  $('#prop').prop('checked', true)_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<label>attr <input id="attr" type="checkbox"></label>_x000D_
<label>prop <input id="prop" type="checkbox"></label>_x000D_
<button type="button">Set checked attr and prop.</button>

For some attributes like disabled on button, adding or removing the content attribute disabled="disabled" always toggles the property (called IDL attribute in HTML5) because http://www.w3.org/TR/html5/forms.html#attr-fe-disabled says:

The disabled IDL attribute must reflect the disabled content attribute.

so you might get away with it, although it is ugly since it modifies HTML without need.

For other attributes like checked="checked" on input type="checkbox", things break, because once you click on it, it becomes dirty, and then adding or removing the checked="checked" content attribute does not toggle checkedness anymore.

This is why you should use mostly .prop, as it affects the effective property directly, instead of relying on complex side-effects of modifying the HTML.

That would be a possibility:

$(document).ready(function(){_x000D_
  $("#topbar").toggle(function(){_x000D_
    $(this).animate({height:40},200);_x000D_
  }, _x000D_
  function(){_x000D_
    $(this).animate({height:10},200);_x000D_
  });_x000D_
});

#topbar {_x000D_
  width: 100%;_x000D_
  height: 10px;_x000D_
  background-color: #000;_x000D_
  color: #FFF;_x000D_
  cursor: pointer;_x000D_
}

<!DOCTYPE html>_x000D_
    <html>_x000D_

      <div id="topbar"> example </div>_x000D_

    </html>

It is working you have to check attr after assigning value

LiveDemo

$('#amount').attr( 'datamin','1000');

alert($('#amount').attr( 'datamin'));?

As @Richard pointed out above, the onClick needs to have a capital 'C'.

$('#stop').click(function() {
     $('next').attr('onClick','stopMoving()');
}

Very simply, use this as the context: http://api.jquery.com/jQuery/#selector-context

var a_href = $('div.cpt', this).find('h2 a').attr('href');

Which says, find 'div.cpt' only inside this

You remove the original image here:

newImg.animate(css, SPEED, function() {
    img.remove();
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And all that's left behind is newImg. Then you reset link references the image using #rocket:

$("#rocket").attr('src', ...

But your newImg doesn't have an id attribute let alone an id of rocket.

To fix this, you need to remove img and then set the id attribute of newImg to rocket:

newImg.animate(css, SPEED, function() {
    var old_id = img.attr('id');
    img.remove();
    newImg.attr('id', old_id);
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/

UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:

$("#resetlink").click(function(){
    clearInterval(timerRocket);
    $("#wrapper").css('top', '250px');
    $('.throbber, .morpher').remove(); // Clear out the new stuff.
    $("#rocket").show();               // Bring the original back.
});

And in the newImg.load function, grab the images original size:

var orig = {
    width: img.width(),
    height: img.height()
};

And finally, the callback for finishing the morphing animation becomes this:

newImg.animate(css, SPEED, function() {
    img.css(orig).hide();
    (callback || function() {})();
});

New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/

The leaking of $('.throbber, .morpher') outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.

If #uploadedfile is an input with type "file" :

var file = $("#uploadedfile")[0].files[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");

Normally this would fire on the change event, like so:

$("#uploadedfile").on("change", function(){
   var file = this.files[0],
       fileName = file.name,
       fileSize = file.size;
   alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
   CustomFileHandlingFunction(file);
});

FIDDLE

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

Yes, MySQL allows this. You can have multiple foreign keys on the same table.

1. Everything is encoded by default!!! This is pretty huge.

2. Declarative helpers can be compiled so you don't need to do anything special to share them. I think they will replace .ascx controls to some extent. You have to jump through some hoops to use an .ascx control in another project.

3. You can make a section required which is nice.

The difference between an operating system and a kernel:

The kernel is a part of an operating system. The operating system is the software package that communicates directly to the hardware and our application. The kernel is the lowest level of the operating system. The kernel is the main part of the operating system and is responsible for translating the command into something that can be understood by the computer. The main functions of the kernel are:

1. memory management
2. network management
3. device driver
4. file management
5. process management

Best solution would be this which is provided by npm documentation.

For Ubuntu suggested solution is Option#2

Brief steps:
Make a directory for global installations:
mkdir ~/.npm-global

Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
npm config get prefix can help you to verify if prefix was updated or not. The result would be <Your Home Directory>/.npm-global

Open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH

Back on the command line, update your system variables:
source ~/.profile

Instead of steps 2-4 you can also use the corresponding ENV variable (e.g. if you don't want to modify ~/.profile):

NPM_CONFIG_PREFIX=~/.npm-global

For Mac suggested solution is Option#3

On Mac OS you can avoid this problem altogether by using the Homebrew package manager

brew install node

You should be able to type "which python" and it will print out a path to python.

or you can type:

python
>>> import re
>>> re.__file__

and it will print a path to the re module and you'll see where python is that way.

Yes, there is one here: http://en.wikipedia.org/wiki/Byte_order_mark#Representations_of_byte_order_marks_by_encoding.

How about making the <div id="mainWrapperDivWithBGImage"> as three divs, where the two outside divs hold the rounded corners images, and the middle div simply has a background-color to match the rounded corner images. Then you could simply place the other elements inside the middle div, or:

#outside_left{width:10px; float:left;}
#outside_right{width:10px; float:right;}
#middle{background-color:#color of rnd_crnrs_foo.gif; float:left;}

Then

HTML:

<div id="mainWrapperDivWithBGImage">
  <div id="outside_left><img src="rnd_crnrs_left.gif" /></div>
  <div id="middle">
    <div id="another_div"><img src="foo.gif" /></div>
  <div id="outside_right><img src="rnd_crnrs_right.gif" /></div>
</div>

You may have to do position:relative; and such.

Unfortunately there really isn't a set set of escape codes since it varies based on the language you are using.

However, keeping a page like the Regular Expression Tools Page or this Regular Expression Cheatsheet can go a long way to help you quickly filter things out.

The perfect solution is:

FOR /F %%i IN ('TYPE "Text file.txt" ^| FIND /C /V ""') DO SET Lines=%%i

The correct way to 'solve' it is to close the connection and forget about the client. The client has closed the connection while you where still writing to it, so he doesn't want to know you, so that's it, isn't it?

In jQuery 1.4:

$("<link/>", {
   rel: "stylesheet",
   type: "text/css",
   href: "/styles/yourcss.css"
}).appendTo("head");

If performance doesn't matter, you could serialize them and compare the results:

var serializer = new XmlSerializer(typeof(TheObjectType));
StringWriter serialized1 = new StringWriter(), serialized2 = new StringWriter();
serializer.Serialize(serialized1, obj1);
serializer.Serialize(serialized2, obj2);
bool areEqual = serialized1.ToString() == serialized2.ToString();

public static IEnumerable<DateTime> GetDateRange(DateTime startDate, DateTime endDate)
{
    if (endDate < startDate)
        throw new ArgumentException("endDate must be greater than or equal to startDate");

    while (startDate <= endDate)
    {
        yield return startDate;
        startDate = startDate.AddDays(1);
    }
}

Theoretically you could just use fopen, then use stream_get_contents.

$stream = fopen("file.php","r");
$string = stream_get_contents($stream);
fclose($stream);

That should read the entire file into $string for you, and should not evaluate it. Though I'm surprised that file_get_contents didn't work when you specified the local path....

In JavaScript try:

encodeURIComponent() 

and in PHP:

urldecode($_POST['field']);

For anyone trying to change og:title meta tags (or any other). I managed to do it this way:

document.querySelector('meta[property="og:title"]').setAttribute("content", "Example with og title meta tag");

Attention that the 'meta[property="og:title"]' contains the word PROPERTY, and not NAME.

TypeScript does something similar to what less or sass does for CSS. They are super sets of it, which means that every JS code you write is valid TypeScript code. Plus you can use the other goodies that it adds to the language, and the transpiled code will be valid js. You can even set the JS version that you want your resulting code on.

Currently TypeScript is a super set of ES2015, so might be a good choice to start learning the new js features and transpile to the needed standard for your project.

size_t is a type that can hold any array index.

Depending on the implementation, it can be any of:

unsigned char

unsigned short

unsigned int

unsigned long

unsigned long long

Here's how size_t is defined in stddef.h of my machine:

typedef unsigned long size_t;

This link just gave me the best answer:

$ wget --no-clobber --convert-links --random-wait -r -p --level 1 -E -e robots=off -U mozilla http://base.site/dir/

Worked like a charm.

I wanted a way to do this without using an extra module. First turn list to string, then append to an array:

dataset_list = ''.join(input_list)
dataset_array = []
for item in dataset_list.split(';'): # comma, or other
    dataset_array.append(item)

I settled for the limitation (to some people a benefit) of having my rows only one line of text high. The CSS to contain long strings then becomes:

.datatable td {
  overflow: hidden; /* this is what fixes the expansion */
  text-overflow: ellipsis; /* not supported in all browsers, but I accepted the tradeoff */
  white-space: nowrap;
}

[edit to add:] After using my own code and initially failing, I recognized a second requirement that might help people. The table itself needs to have a fixed layout or the cells will just keep trying to expand to accomodate contents no matter what. If DataTables styles or your own styles don't already do so, you need to set it:

table.someTableClass {
  table-layout: fixed
}

Now that text is truncated with ellipses, to actually "see" the text that is potentially hidden you can implement a tooltip plugin or a details button or something. But a quick and dirty solution is to use JavaScript to set each cell's title to be identical to its contents. I used jQuery, but you don't have to:

  $('.datatable tbody td').each(function(index){
    $this = $(this);
    var titleVal = $this.text();
    if (typeof titleVal === "string" && titleVal !== '') {
      $this.attr('title', titleVal);
    }
  });

DataTables also provides callbacks at the row and cell rendering levels, so you could provide logic to set the titles at that point instead of with a jQuery.each iterator. But if you have other listeners that modify cell text, you might just be better off hitting them with the jQuery.each at the end.

This entire truncation method will ALSO have a limitation you've indicated you're not a fan of: by default columns will have the same width. I identify columns that are going to be consistently wide or consistently narrow, and explicitly set a percentage-based width on them (you could do it in your markup or with sWidth). Any columns without an explicit width get even distribution of the remaining space.

That might seem like a lot of compromises, but the end result was worth it for me.

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

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

A little alternative to @gasp´s answer is to simply put the actual domain name you are running it from. Docs: https://httpd.apache.org/docs/2.4/upgrading.html

In the following example, there is no authentication and all hosts in the example.org domain are allowed access; all other hosts are denied access.

Apache 2.2 configuration:

Order Deny,Allow
Deny from all
Allow from example.org

Apache 2.4 configuration:

Require host example.org

Sure you can.

ALTER TABLE myTable ALTER COLUMN myColumn int NULL

Just substitute int for whatever datatype your column is.

Each answer is missing some points, so here is my solution:

$("#input").on("input", function(e) {_x000D_
  var input = $(this);_x000D_
  var val = input.val();_x000D_
_x000D_
  if (input.data("lastval") != val) {_x000D_
    input.data("lastval", val);_x000D_
_x000D_
    //your change action goes here _x000D_
    console.log(val);_x000D_
  }_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" id="input">_x000D_
<p>Try to drag the letters and copy paste</p>

The Input Event fires on Keyboard input, Mouse Drag, Autofill and Copy-Paste tested on Chrome and Firefox. Checking for previous value makes it detect real changes, which means not firing when pasting the same thing or typing the same character or etc.

Working example: http://jsfiddle.net/g6pcp/473/

update:

And if you like to run your change function only when user finishes typing and prevent firing the change action several times, you could try this:

var timerid;_x000D_
$("#input").on("input", function(e) {_x000D_
  var value = $(this).val();_x000D_
  if ($(this).data("lastval") != value) {_x000D_
_x000D_
    $(this).data("lastval", value);_x000D_
    clearTimeout(timerid);_x000D_
_x000D_
    timerid = setTimeout(function() {_x000D_
      //your change action goes here _x000D_
      console.log(value);_x000D_
    }, 500);_x000D_
  };_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" id="input">

If user starts typing (e.g. "foobar") this code prevents your change action to run for every letter user types and and only runs when user stops typing, This is good specially for when you send the input to the server (e.g. search inputs), that way server does only one search for foobar and not six searches for f and then fo and then foo and foob and so on.

Try this:

KeyValuePair<string, string> pair = (KeyValuePair<string,string>)this.ComboBox.SelectedItem;

Just right click on a conflicting file and add it to the index after resolving conflicts.

You're better off using typed np.arrays, and then pass the data and column names as a dictionary.

import numpy as np
import pandas as pd
# Feature: np arrays are 1: efficient, 2: can be pre-sized
x = np.array(['a', 'b'], dtype=object)
y = np.array([ 1 ,  2 ], dtype=np.int32)
df = pd.DataFrame({
   'x' : x,    # Feature: column name is near data array
   'y' : y,
   }
 )

First of all, tf.train.GradientDescentOptimizer is designed to use a constant learning rate for all variables in all steps. TensorFlow also provides out-of-the-box adaptive optimizers including the tf.train.AdagradOptimizer and the tf.train.AdamOptimizer, and these can be used as drop-in replacements.

However, if you want to control the learning rate with otherwise-vanilla gradient descent, you can take advantage of the fact that the learning_rate argument to the tf.train.GradientDescentOptimizer constructor can be a Tensor object. This allows you to compute a different value for the learning rate in each step, for example:

learning_rate = tf.placeholder(tf.float32, shape=[])
# ...
train_step = tf.train.GradientDescentOptimizer(
    learning_rate=learning_rate).minimize(mse)

sess = tf.Session()

# Feed different values for learning rate to each training step.
sess.run(train_step, feed_dict={learning_rate: 0.1})
sess.run(train_step, feed_dict={learning_rate: 0.1})
sess.run(train_step, feed_dict={learning_rate: 0.01})
sess.run(train_step, feed_dict={learning_rate: 0.01})

Alternatively, you could create a scalar tf.Variable that holds the learning rate, and assign it each time you want to change the learning rate.

You map your dispatcher on *.do:

<servlet-mapping>
   <servlet-name>Dispatcher</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>

but your controller is mapped on an url without .do:

@RequestMapping("/editPresPage")

Try changing this to:

@RequestMapping("/editPresPage.do")

In order to serve up a static CSS file in express app (i.e. use a css style file to style ejs "templates" files in express app). Here are the simple 3 steps that need to happen:

1. Place your css file called "styles.css" in a folder called "assets" and the assets folder in a folder called "public". Thus the relative path to the css file should be "/public/assets/styles.css"

2. In the head of each of your ejs files you would simply call the css file (like you do in a regular html file) with a <link href=… /> as shown in the code below. Make sure you copy and paste the code below directly into your ejs file <head> section

   <link href= "/public/assets/styles.css" rel="stylesheet" type="text/css" />
   

3. In your server.js file, you need to use the app.use() middleware. Note that a middleware is nothing but a term that refers to those operations or code that is run between the request and the response operations. By putting a method in middleware, that method will automatically be called everytime between the request and response methods. To serve up static files (such as a css file) in the app.use() middleware there is already a function/method provided by express called express.static(). Lastly, you also need to specify a request route that the program will respond to and serve up the files from the static folder everytime the middleware is called. Since you will be placing the css files in your public folder. In the server.js file, make sure you have the following code:

   // using app.use to serve up static CSS files in public/assets/ folder when /public link is called in ejs files
   // app.use("/route", express.static("foldername"));
   app.use('/public', express.static('public'));
   

After following these simple 3 steps, every time you res.render('ejsfile') in your app.get() methods you will automatically see the css styling being called. You can test by accessing your routes in the browser.

This error is because your server doesn't have a valid SSL certificate. Hence we need to tell the client to use a different TrustManager. Here is a sample code:

SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {

    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", 443, ssf));

client = new DefaultHttpClient(ccm, base.getParams());

Once upon a time Microsoft, like everyone else, used 7-bit character sets, and they invented their own when it suited them, though they kept ASCII as a core subset. Then they realised the world had moved on to 8-bit encodings and that there were international standards around, such as the ISO-8859 family. In those days, if you wanted to get hold of an international standard and you lived in the US, you bought it from the American National Standards Institute, ANSI, who republished international standards with their own branding and numbers (that's because the US government wants conformance to American standards, not international standards). So Microsoft's copy of ISO-8859 said "ANSI" on the cover. And because Microsoft weren't very used to standards in those days, they didn't realise that ANSI published lots of other standards as well. So they referred to the standards in the ISO-8859 family (and the variants that they invented, because they didn't really understand standards in those days) by the name on the cover, "ANSI", and it found its way into Microsoft user documentation and hence into the user community. That was about 30 years ago, but you still sometimes hear the name today.

Use the perror command:

$ perror 28
OS error code  28:  No space left on device

Unless error codes are different on your system, your file system is full.

Below is a re-write of a previously posted function:

def addBinary(a, b): # Example: a = '11' + b =' 100' returns as '111'.

Copies a directory named html & all its contents to a destination directory in silent mode. If the destination directory is not present it will still create it.

@echo off
TITLE Copy Folder with Contents

set SOURCE=C:\labs
set DESTINATION=C:\Users\MyUser\Desktop\html

xcopy %SOURCE%\html\* %DESTINATION%\* /s /e /i /Y >NUL

1. /S Copies directories and subdirectories except empty ones.

2. /E Copies directories and subdirectories, including empty ones. Same as /S /E. May be used to modify /T.

3. /I If destination does not exist and copying more than one file, assumes that destination must be a directory.

4. /Y Suppresses prompting to confirm you want to overwrite an existing destination file.

I would suggest to read up a bit on the syntax. See here.

In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:

<script type="javascript">
    day = new Array(<?php echo implode(',', $day); ?>);
    week = new Array(<?php echo implode(',',$week); ?>);
    month = new Array(<?php echo implode(',',$month); ?>);

    <!--  Then pass it to the JavaScript function:   -->

    drawChart(<?php echo count($day); ?>, day, week, month);
</script>

Here's some succinct Powershell code to apply new permissions to a folder by modifying it's existing ACL (Access Control List).

# Get the ACL for an existing folder
$existingAcl = Get-Acl -Path 'C:\DemoFolder'

# Set the permissions that you want to apply to the folder
$permissions = $env:username, 'Read,Modify', 'ContainerInherit,ObjectInherit', 'None', 'Allow'

# Create a new FileSystemAccessRule object
$rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permissions

# Modify the existing ACL to include the new rule
$existingAcl.SetAccessRule($rule)

# Apply the modified access rule to the folder
$existingAcl | Set-Acl -Path 'C:\DemoFolder'

Each of the values in the $permissions variable list pertain to the parameters of this constructor for the FileSystemAccessRule class.

Try installing mod_ssl using following command:

yum install mod_ssl

and then reload and restart your Apache server using following commands:

systemctl reload httpd.service
systemctl restart httpd.service

This should work for most of the cases.

The problem is that /var/www doesn't exist either, and mkdir isn't recursive by default -- it expects the immediate parent directory to exist.

Use:

mkdir -p /var/www/app

...or install a package that creates a /var/www prior to reaching this point in your Dockerfile.

The definition of an inline function doesn't have to be in a header file but, because of the one definition rule (ODR) for inline functions, an identical definition for the function must exist in every translation unit that uses it.

The easiest way to achieve this is by putting the definition in a header file.

If you want to put the definition of a function in a single source file then you shouldn't declare it inline. A function not declared inline does not mean that the compiler cannot inline the function.

Whether you should declare a function inline or not is usually a choice that you should make based on which version of the one definition rules it makes most sense for you to follow; adding inline and then being restricted by the subsequent constraints makes little sense.

Just add in the '0' in your select.

INSERT INTO table_name (a,b,c,d)

In my case after downgrading from .NET 4.5 to .NET 4.0 project was working fine on a local machine, but was failing on server after publishing.

Turns out that destination had some old assemblies, which were still referencing .NET 4.5.

Fixed it by enabling publishing option "Delete all existing files prior to publish"

"commentLine" is the name of function you are looking for. This function coment and uncoment with the same keybinding

If the HTML is not XML you can't do it with etree. But even then, you don't have to use an external library for parsing a HTML table. In python 3 you can reach your goal with HTMLParser from html.parser. I've the code of the simple derived HTMLParser class here in a github repo.

You can use that class (here named HTMLTableParser) the following way:

import urllib.request
from html_table_parser import HTMLTableParser

target = 'http://www.twitter.com'

# get website content
req = urllib.request.Request(url=target)
f = urllib.request.urlopen(req)
xhtml = f.read().decode('utf-8')

# instantiate the parser and feed it
p = HTMLTableParser()
p.feed(xhtml)
print(p.tables)

The output of this is a list of 2D-lists representing tables. It looks maybe like this:

[[['   ', ' Anmelden ']],
 [['Land', 'Code', 'Für Kunden von'],
  ['Vereinigte Staaten', '40404', '(beliebig)'],
  ['Kanada', '21212', '(beliebig)'],
  ...
  ['3424486444', 'Vodafone'],
  ['  Zeige SMS-Kurzwahlen für andere Länder ']]]

Offset Means "the amount or distance by which something is out of line". Margin or Borders are something which makes the actual height or width of an HTML element "out of line". It will help you to remember that :

• offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.

On the other hand, clientHeight is something which is you can say kind of the opposite of OffsetHeight. It doesn't include the border or margins. It does include the padding because it is something that resides inside of the HTML container, so it doesn't count as extra measurements like margin or border. So :

• clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.

ScrollHeight is all the scrollable area, so your scroll will never run over your margin or border, so that's why scrollHeight doesn't include margin or borders but yeah padding does. So:

• scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.

If you want to set your custom RGB color try this:

self.view.backgroundColor = UIColor(red: 20/255.0, green: 106/255.0, blue: 93/255.0, alpha: 1)

Don't forget to keep /255.0 for every color

From the Package Manager console window, often whatever command you used to install a package can be used to uninstall that package. Simply replace the INSTALL command with UNINSTALL.

For example, to install PowerTCPTelnet, the command is:

Install-Package PowerTCPTelnet -Version 4.4.9

To uninstall same, the command is:

Uninstall-Package PowerTCPTelnet -Version 4.4.9

Angular Js Demo Code :-

angular.module('ModuleName',[]).controller('main', ['$http', function($http){

                var formData = { password: 'test pwd', email : 'test email' };
                var postData = 'myData='+JSON.stringify(formData);
                $http({
                        method : 'POST',
                        url : 'resources/curl.php',
                        data: postData,
                        headers : {'Content-Type': 'application/x-www-form-urlencoded'}  

                }).success(function(res){
                        console.log(res);
                }).error(function(error){
                        console.log(error);
        });

        }]);

Server Side Code :-

<?php


// it will print whole json string, which you access after json_decocde in php
$myData = json_decode($_POST['myData']);
print_r($myData);

?>

Due to angular behaviour there is no direct method for normal post behaviour at PHP server, so you have to manage it in json objects.

I think that most of the time when people ask this question, they have build a site with only divs, and now one of the div needs to be a link.

I seen someone use a transparent empty image, PNG, inside an anchor tag just to make a link inside a div, and the image was the same size as the div.

Pretty sad actually...but it works...

Also ensure that you have the correct version of Tomcat for the CPU type. I had installed a 64bit tomcat on a 32bit O/S but it was giving me the JAVA_HOME exception when that wasn't the case at all.

There is an awesome library for doing that that I recently discovered. It's simple to use and the result is quite neat: d3-tip.

You can see an example here:

Basically, all you have to do is to download(index.js), include the script:

<script src="index.js"></script>

and then follow the instructions from here (same link as example)

But for your code, it would be something like:

define the method:

var tip = d3.tip()
  .attr('class', 'd3-tip')
  .offset([-10, 0])
  .html(function(d) {
    return "<strong>Frequency:</strong> <span style='color:red'>" + d.frequency + "</span>";
  })

create your svg (as you already do)

var svg = ...

call the method:

svg.call(tip);

add tip to your object:

vis.selectAll("circle")
   .data(datafiltered).enter().append("svg:circle")
...
   .on('mouseover', tip.show)
   .on('mouseout', tip.hide)

Don't forget to add the CSS:

<style>
.d3-tip {
  line-height: 1;
  font-weight: bold;
  padding: 12px;
  background: rgba(0, 0, 0, 0.8);
  color: #fff;
  border-radius: 2px;
}

/* Creates a small triangle extender for the tooltip */
.d3-tip:after {
  box-sizing: border-box;
  display: inline;
  font-size: 10px;
  width: 100%;
  line-height: 1;
  color: rgba(0, 0, 0, 0.8);
  content: "\25BC";
  position: absolute;
  text-align: center;
}

/* Style northward tooltips differently */
.d3-tip.n:after {
  margin: -1px 0 0 0;
  top: 100%;
  left: 0;
}
</style>

You can iterate through JavaScript objects this way:

for(var attributename in myobject){
    console.log(attributename+": "+myobject[attributename]);
}

myobject could be your json.data

As the answer by @plaul mentions TouchableOpacity, here is an example of how you can use that;

  <TouchableOpacity
    style={someStyles}
    onPress={doSomething}
  >
    <Text>Press Here</Text>
  </TouchableOpacity>

If you're running ubuntu container directly without a local Dockerfile you can ssh into the container and enable root control by entering su then apt-get install -y wget

This usually has to do with a selector not being used properly. Check and make sure that you are using the jQuery selectors like intended. For example I had this problem when creating a click method:

$("[editButton]").click(function () {
    this.css("color", "red");
});

Because I was not using the correct selector method $(this) for jQuery it gave me the same error.

So simply enough, check your selectors!

You could specify type like this:

[string[]] $a = "This", "Is", "a", "cat"

Checking the type:

$a.GetType()

Confirms:

    IsPublic IsSerial Name                                     BaseType
    -------- -------- ----                                     --------
    True     True     String[]                                 System.Array

Outputting $a:

PS C:\> $a 
This 
Is 
a 
cat

You can use try-catch block to check for integer value

for eg:

User inputs in form of string

try
{
   int num=Integer.parseInt("Some String Input");
}
catch(NumberFormatException e)
{
  //If number is not integer,you wil get exception and exception message will be printed
  System.out.println(e.getMessage());
}

CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.

They often forget that iterator must convert to const_iterator but not the other way around. Here is a way to do that:

template<class T, class Tag = void>
class IntrusiveSlistIterator
   : public std::iterator<std::forward_iterator_tag, T>
{
    typedef SlistNode<Tag> Node;
    Node* node_;

public:
    IntrusiveSlistIterator(Node* node);

    T& operator*() const;
    T* operator->() const;

    IntrusiveSlistIterator& operator++();
    IntrusiveSlistIterator operator++(int);

    friend bool operator==(IntrusiveSlistIterator a, IntrusiveSlistIterator b);
    friend bool operator!=(IntrusiveSlistIterator a, IntrusiveSlistIterator b);

    // one way conversion: iterator -> const_iterator
    operator IntrusiveSlistIterator<T const, Tag>() const;
};

In the above notice how IntrusiveSlistIterator<T> converts to IntrusiveSlistIterator<T const>. If T is already const this conversion never gets used.

Well in the end I had to compromise by implementing a HTML5/CSS solution, forgoing increment buttons in IE (they're a bit broke in FF anyway!), but gaining number validation that the JQuery spinner doesn't provide. Though I have had to go with a step of whole numbers.

span.gbp {_x000D_
    float: left;_x000D_
    text-align: left;_x000D_
}_x000D_
_x000D_
span.gbp::before {_x000D_
    float: left;_x000D_
    content: "\00a3"; /* £ */_x000D_
    padding: 3px 4px 3px 3px;_x000D_
}_x000D_
_x000D_
span.gbp input {_x000D_
     width: 280px !important;_x000D_
}

<label for="broker_fees">Broker Fees</label>_x000D_
<span class="gbp">_x000D_
    <input type="number" placeholder="Enter whole GBP (&pound;) or zero for none" min="0" max="10000" step="1" value="" name="Broker_Fees" id="broker_fees" required="required" />_x000D_
</span>

The validation is a bit flaky across browsers, where IE/FF allow commas and decimal places (as long as it's .00), where as Chrome/Opera don't and want just numbers.

I guess it's a shame that the JQuery spinner won't work with a number type input, but the docs explicitly state not to do that :-( and I'm puzzled as to why a number spinner widget allows input of any ascii char?

See ?which.max

> which.max( matrix[,2] )
[1] 2

I have used Botan to perform this operation and others before. AraK has pointed out Crypto++. I guess both libraries are perfectly valid. Now it is up to you :-).

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

Datetime is a datatype.

Timestamp is a method for row versioning. In fact, in sql server 2008 this column type was renamed (i.e. timestamp is deprecated) to rowversion. It basically means that every time a row is changed, this value is increased. This is done with a database counter which automatically increase for every inserted or updated row.

For more information:

http://www.sqlteam.com/article/timestamps-vs-datetime-data-types

What the code does, is that the number 8000 is counting up from 0 to 8000. The problem is, that it is placed at the middle of quite long page, and once user scroll down and actually see the number, the animation is already dine. I would like to trigger the counter, once it appears in the viewport.

JS:

$('.count').each(function () {
                $(this).prop('Counter',0).animate({
                        Counter: $(this).text()
                }, {
                        duration: 4000,
                        easing: 'swing',
                        step: function (now) {
                                $(this).text(Math.ceil(now));
                        }
                });
            });

And HTML:

 <span class="count">8000</span>

The n module worked for me.

Run this code to clear npm’s cache, install n, and install the latest stable version of Node:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

See: http://www.hostingadvice.com/how-to/update-node-js-latest-version/
And: https://www.npmjs.com/package/n

To install a specific version of node:

sudo n 6.11.2

To check what version:

node -v

You might need to restart

Another option is to do like this:

<html>
    <body>
    <?php
    //...php code...  
    ?>
    <script type="text/javascript">
        document.write("Hello World!");
    </script>
    <?php
    //....php code...
    ?>
    </body>
</html>

and if you want to use PHP inside your JavaScript, do like this:

<html>
    <body>
    <?php
        $text = "Hello World!";
    ?>
    <script type="text/javascript">
        document.write("<?php echo $text ?>");
    </script>
    <?php
    //....php code...
    ?>
    </body>
</html>

Hope this can help.

Tbl.ListRows.Add doesn't work for me and I believe lot others are facing the same problem. I use the following workaround:

    'First check if the last row is empty; if not, add a row
    If table.ListRows.count > 0 Then
        Set lastRow = table.ListRows(table.ListRows.count).Range
        For col = 1 To lastRow.Columns.count
            If Trim(CStr(lastRow.Cells(1, col).Value)) <> "" Then
                lastRow.Cells(1, col).EntireRow.Insert
                'Cut last row and paste to second last
                lastRow.Cut Destination:=table.ListRows(table.ListRows.count - 1).Range
                Exit For
            End If
        Next col
    End If

    'Populate last row with the form data
    Set lastRow = table.ListRows(table.ListRows.count).Range
    Range("E7:E10").Copy
    lastRow.PasteSpecial Transpose:=True
    Range("E7").Select
    Application.CutCopyMode = False

Hope it helps someone out there.

It depends on which range you're talking about, but the dynamic range goes up to 65535 or 2^16-1 (16 bits).

You can leave action blank or use this code:

<form name="form1" id="mainForm" method="post" enctype="multipart/form-data" action="<?php echo $_SERVER['REQUEST_URI'];?>">
</form>

You can also set the 'dashed' option when setting your terminal, for instance:

set term pdf dashed

This error could also happen because of version mismatch of jmeter and java. As jmeter versions supports different java versions as below.

Disclamer

This is not intended to be "the good answer", as this question ask explicitly for ObjectiveC. As Apple introduced Swift at the WWDC14, I'd like to share the different ways to use block (or closures) in Swift.

Hello, Swift

You have many ways offered to pass a block equivalent to function in Swift.

I found three.

To understand this I suggest you to test in playground this little piece of code.

func test(function:String -> String) -> String
{
    return function("test")
}

func funcStyle(s:String) -> String
{
    return "FUNC__" + s + "__FUNC"
}
let resultFunc = test(funcStyle)

let blockStyle:(String) -> String = {s in return "BLOCK__" + s + "__BLOCK"}
let resultBlock = test(blockStyle)

let resultAnon = test({(s:String) -> String in return "ANON_" + s + "__ANON" })


println(resultFunc)
println(resultBlock)
println(resultAnon)

Swift, optimized for closures

As Swift is optimized for asynchronous development, Apple worked more on closures. The first is that function signature can be inferred so you don't have to rewrite it.

Access params by numbers

let resultShortAnon = test({return "ANON_" + $0 + "__ANON" })

Params inference with naming

let resultShortAnon2 = test({myParam in return "ANON_" + myParam + "__ANON" })

Trailing Closure

This special case works only if the block is the last argument, it's called trailing closure

Here is an example (merged with inferred signature to show Swift power)

let resultTrailingClosure = test { return "TRAILCLOS_" + $0 + "__TRAILCLOS" }

Finally:

Using all this power what I'd do is mixing trailing closure and type inference (with naming for readability)

PFFacebookUtils.logInWithPermissions(permissions) {
    user, error in
    if (!user) {
        println("Uh oh. The user cancelled the Facebook login.")
    } else if (user.isNew) {
        println("User signed up and logged in through Facebook!")
    } else {
        println("User logged in through Facebook!")
    }
}

try this:

select salesid,count (salesid) from AXDelNotesNoTracking group by salesid having count (salesid) >1

I encountered a similar issue, but putting it in my page’s module didn’t work.

I had created a component, which needed a pipe. This component was declared and exported in a ComponentsModule file, which holds all of the app’s custom components.

I had to put my PipesModule in my ComponentsModule as an import, in order for these components to use these pipes and not in the page’s module using that component.

Type info variables to list "All global and static variable names".

Type info locals to list "Local variables of current stack frame" (names and values), including static variables in that function.

Type info args to list "Arguments of the current stack frame" (names and values).

I'd check out SQLAlchemy

It's really easy to use and the models you work with aren't bad at all. Django uses SQLAlchemy for it's ORM but using it by itself lets you use it's full power.

Here's a small example on creating and selecting orm objects

>>> ed_user = User('ed', 'Ed Jones', 'edspassword')
>>> session.add(ed_user)
>>> our_user = session.query(User).filter_by(name='ed').first() 
>>> our_user
    <User('ed','Ed Jones', 'edspassword')>

Just replace from bottom and add this

tv.setLayoutParams(new ViewGroup.LayoutParams(
    ViewGroup.LayoutParams.WRAP_CONTENT,
    ViewGroup.LayoutParams.WRAP_CONTENT));

before

llview.addView(tv);

You can use context manager to run the faulty function and assert it raises the exception with a certain message using assertRaisesMessage

with self.assertRaisesMessage(SomeException,'Some error message e.g 404 Not Found'):
    faulty_funtion()

Personally I would use something like mplayer with the audio pass though option eg -oac copy

You can do something like this

Session session = app.factory.openSession();
CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery query = builder.createQuery();
Root<Users> root = query.from(Users.class);
query.select(root.get("firstname"));
String name = session.createQuery(query).getSingleResult();

where you can change "firstname" with the name of the column you want.

just window.close() is OK, why should write in jQuery?

If your test and webapp are in the same Maven project, you can use a property in the project POM. Then you can filter certain files which will allow Maven to set the property in those files. There are different ways to filter, but the most common is during the resources phase - http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-description.html

If the test and webapp are in different Maven projects, you can put the property in settings.xml, which is in your maven repository folder (C:\Documents and Settings\username.m2) on Windows. You will still need to use filtering or some other method to read the property into your test and webapp.

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

import io, pygame, zipfile
archive = zipfile.ZipFile('images.zip', 'r')

# read bytes from archive
img_data = archive.read('img_01.png')

# create a pygame-compatible file-like object from the bytes
bytes_io = io.BytesIO(img_data)

img = pygame.image.load(bytes_io)

I was trying to figure this out for myself just now and thought this might be useful for anyone who comes across this question in the future.

Many people have given a great explanation here about @Mock vs @InjectMocks. I like it, but I think our tests and application should be written in such a way that we shouldn't need to use @InjectMocks.

public class MyException extends Exception {
        // special exception code goes here
}

Throw it as:

 throw new MyException ("Something happened")

Catch as:

catch (MyException e)
{
   // something
}

Using a single sed

echo "/var/cpanel/users/joebloggs:DNS9=domain.com" | sed 's/.*\/\(.*\):.*/\1/'

Here is settings.xml --> C:\maven\conf\settings.xml

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

Another thing you could do is to create a session variable that gets set in the code behind and then check the state of that variable and then run your javascript. The good thing is this will allow you to run your script right where you want to instead of having to figure out if you want it to run in the DOM or globally.

Something like this: Code behind:

Session["newuser"] = "false" 

In javascript

var newuser = '<%=Session["newuser"]%>';
 if (newuser == "yes")
     startTutorial();  

First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

$count = DB::table('category_issue')->count();

will give you the number of items.

For more detailed information check Fluent Query Builder section in beautiful Laravel Documentation.

Arrays make sense where the exact number of items will be known, and where searching by index makes sense. For example, if I wanted to store the exact state of my video output at a given moment without compression I would probably use an array of size [1024][768]. This will provide me with exactly what I need, and a list would be much, much slower to get the value of a given pixel. In places where an array does not make sense there are generally better data types than a list to deal with data effectively.

I was able to stop via this on Windows for Angular 8:

Step 1: Find 4200 process

netstat -ano | findstr :4200

Step 2: Kill that process:

taskkill /PID <PID> /F

Investigating persistent sessions myself I have found that it's simply not worth the security risk. Use it if you absolutely have to, but you should consider such a session only weakly authenticated and force a new login for anything that could be of value to an attacker.

The reason being of course is that your cookies containing your persistent session are so easily stolen.

4 ways to steal your cookies (from a comment by Jens Roland on the page @splattne based his answer on):

1. By intercepting it over an unsecure line (packet sniffing / session hijacking)
2. By directly accessing the user's browser (via either malware or physical access to the box)
3. By reading it from the server database (probably SQL Injection, but could be anything)
4. By an XSS hack (or similar client-side exploit)

SELECT DISTINCT 
FIRST_VALUE(ID) OVER (Partition by Game ORDER BY Point) AS ID,
Game,
FIRST_VALUE(Point) OVER (Partition by Game ORDER BY Point) AS Point
FROM #T

It is important to notice that in C# the char type is stored as Unicode UTF-16.

From ASCII equivalent integer to char

char c = (char)88;

or

char c = Convert.ToChar(88)

From char to ASCII equivalent integer

int asciiCode = (int)'A';

The literal must be ASCII equivalent. For example:

string str = "X?????????";
Console.WriteLine((int)str[0]);
Console.WriteLine((int)str[1]);

will print

X
3626

Extended ASCII ranges from 0 to 255.

From default UTF-16 literal to char

Using the Symbol

char c = 'X';

Using the Unicode code

char c = '\u0058';

Using the Hexadecimal

char c = '\x0058';

Just to clarify Andrew Marshall's solution for using time_ago_in_words
(For Rails 3.0 and Rails 4.0)

If you are in a view

<%= time_ago_in_words(Date.today - 1) %>

If you are in a controller

include ActionView::Helpers::DateHelper
def index
  @sexy_date = time_ago_in_words(Date.today - 1)
end

Controllers do not have the module ActionView::Helpers::DateHelper imported by default.

N.B. It is not "the rails way" to import helpers into your controllers. Helpers are for helping views. The time_ago_in_words method was decided to be a view entity in the MVC triad. (I don't agree but when in rome...)

PHP by itself has no SMS module or functions and doesn't allow you to send SMS.

SMS ( Short Messaging System) is a GSM technology an you need a GSM provider that will provide this service for you and may have an PHP API implementation for it.

Usually people in telecom business use Asterisk to handle calls and sms programming.

Does the class org.apache.maven.shared.filtering.MavenFilteringException exist in file:/C:/Users/utopcu/.m2/repository/org/apache/maven/shared/maven-filtering/1.0-beta-2/maven-filtering-1.0-beta-2.jar?

The error message suggests that it doesn't. Maybe the JAR was corrupted somehow.

I'm also wondering where the version 1.0-beta-2 comes from; I have 1.0 on my disk. Try version 2.3 of the WAR plugin.

It seems that IDLE changes its current working dir to location of the script that is executed, while when running the script using cmd doesn't do that and it leaves CWD as it is.

To change current working dir to the one containing your script you can use:

import os
os.chdir(os.path.dirname(__file__))
print(os.getcwd())

The __file__ variable is available only if you execute script from file, and it contains path to the file. More on it here: Python __file__ attribute absolute or relative?

Other alternative:

JAXBElement<String> element = new JAXBElement<>(new QName("Your localPart"),
                                                String.class, "Your message");

Then:

System.out.println(element.getValue()); // Result: Your message

Google led me to this solution (base64_encode). Hope this helps!

Looking at your own answer @Bog, I think you want;

$plugin_dir_path = dirname(__FILE__);

What about using a tabular inside \author{}, just like in IEEE macros:

\documentclass{article}
\begin{document}
\title{Hello, World}
\author{
\begin{tabular}[t]{c@{\extracolsep{8em}}c} 
I. M. Author  & M. Y. Coauthor \\
My Department & Coauthor Department \\ 
My Institute & Coauthor Institute \\
email, address & email, address
\end{tabular}
}
\maketitle    
\end{document}

This will produce two columns authors with any documentclass.

Results:

why not both to be sure?

if(opener.document){
  $("#testdiv",opener.document).doStuff();
}else{
  $("#testdiv",window.opener).doStuff();
}

Unlike proposed by Nicolas, the meta tag isn’t actually ignored by the browsers. However, the Content-Type HTTP header always has precedence over the presence of a meta tag in the document.

So make sure that you either send the correct encoding via the HTTP header, or don’t send this HTTP header at all (not recommended). The meta tag is mainly a fallback option for local documents which aren’t sent via HTTP traffic.

Using HTML entities should also be considered a workaround – that’s tiptoeing around the real problem. Configuring the web server properly prevents a lot of nuisance.

In addition to others' proposals, there is another option to handle that issue.

If your application should behave the same in case of lack of "href" attribute, as in case of it being empty, just replace this:

var theHref = $(obj.mainImg_select).attr('href');

with this:

var theHref = $(obj.mainImg_select).attr('href') || '';

which will treat empty string ('') as the default, if the attribute has not been found.

But it really depends, on how you want to handle undefined "href" attribute. This answer assumes you will want to handle it as if it was empty string.

I had the same on Windows. My solution was to get which port the debug wants to connect to. (In IntelliJ a red rectangle already giving the info: "Error running Tomcat: Unable to open debugger port (127.0.0.1:XXXXX): ... Already in use...") Let's say XXXXX is the port number. Then i searched for the problem and the PID in a cmd window:

netstat -ano | find "CLOSE_WAIT" | find ":XXXXX"

I got the PID number as the last number in the result line. (Let's say YYYY) Finally:

TASKKILL /PID YYYY

An extra info: Winscp logged out meanwhile, probably it was causing my problem. :)

the proper implementation would be:

if( callback ) callback();

this makes the callback parameter optional..

I added the control to the Triggers tag in the update panel:

    </ContentTemplate>
    <Triggers>
        <asp:PostBackTrigger ControlID="exportLinkButton" />
    </Triggers>
</asp:UpdatePanel>

This way the exportLinkButton will trigger the UpdatePanel to update.

I suggest "Computer Science Unplugged" as a complementary didactical material.

In order to execute simple queries and return to my shell script, I think this works well:

$ sqlite3 example.db 'SELECT * FROM some_table;'

I am assuming that you are wanting to add items to a ComboBox on an Windows form. Although Klaus is on the right track I believe that the ListItem class is a member of the System.Web.UI.WebControls namespace. So you shouldn't be using it in a Windows forms solution. You can, however, create your own class that you can use in its place. Create a simple class called MyListItem (or whatever name you choose) like this:

Public Class MyListItem
    Private mText As String
    Private mValue As String

    Public Sub New(ByVal pText As String, ByVal pValue As String)
        mText = pText
        mValue = pValue
    End Sub

    Public ReadOnly Property Text() As String
        Get
            Return mText
        End Get
    End Property

    Public ReadOnly Property Value() As String
        Get
            Return mValue
        End Get
    End Property

    Public Overrides Function ToString() As String
        Return mText
    End Function
End Class

Now when you want to add the items to your ComboBox you can do it like this:

myComboBox.Items.Add(New MyListItem("Text to be displayed", "value of the item"))

Now when you want to retrieve the value of the selected item from your ComboBox you can do it like this:

Dim oItem As MyListItem = CType(myComboBox.SelectedItem, MyListItem)
MessageBox.Show("The Value of the Item selected is: " & oItem.Value)

One of the keys here is overriding the ToString method in the class. This is where the ComboBox gets the text that is displayed.

Matt made an excellent point, in his comment below, about using Generics to make this even more flexible. So I wondered what that would look like.

Here's the new and improved GenericListItem class:

Public Class GenericListItem(Of T)
    Private mText As String
    Private mValue As T

    Public Sub New(ByVal pText As String, ByVal pValue As T)
        mText = pText
        mValue = pValue
    End Sub

    Public ReadOnly Property Text() As String
        Get
            Return mText
        End Get
    End Property

    Public ReadOnly Property Value() As T
        Get
            Return mValue
        End Get
    End Property

    Public Overrides Function ToString() As String
        Return mText
    End Function
End Class

And here is how you would now add Generic items to your ComboBox. In this case an Integer:

Me.myComboBox.Items.Add(New GenericListItem(Of Integer)("Text to be displayed", 1))

And now the retrieval of the item:

Dim oItem As GenericListItem(Of Integer) = CType(Me.myComboBox.SelectedItem, GenericListItem(Of Integer))
MessageBox.Show("The value of the Item selected is: " & oItem.Value.ToString())

Keep in mind that the type Integer can be any type of object or value type. If you want it to be an object from one of your own custom classes that's fine. Basically anything goes with this approach.

Call the 2-arg constructor: For compatibility with Android O, call support-v4 NotificationCompat.Builder(Context context, String channelId). When running on Android N or earlier, the channelId will be ignored. When running on Android O, also create a NotificationChannel with the same channelId.

Out of date sample code: The sample code on several JavaDoc pages such as Notification.Builder calling new Notification.Builder(mContext) is out of date.

Deprecated constructors: Notification.Builder(Context context) and v4 NotificationCompat.Builder(Context context) are deprecated in favor of Notification[Compat].Builder(Context context, String channelId). (See Notification.Builder(android.content.Context) and v4 NotificationCompat.Builder(Context context).)

Deprecated class: The entire class v7 NotificationCompat.Builder is deprecated. (See v7 NotificationCompat.Builder.) Previously, v7 NotificationCompat.Builder was needed to support NotificationCompat.MediaStyle. In Android O, there's a v4 NotificationCompat.MediaStyle in the media-compat library's android.support.v4.media package. Use that one if you need MediaStyle.

API 14+: In Support Library from 26.0.0 and higher, the support-v4 and support-v7 packages both support a minimum API level of 14. The v# names are historical.

You can learn datetime formatting in sql server here

Could you post the exact query? The ExecuteNonQuery method returns the @@ROWCOUNT Sql Server variable what ever it is after the last query has executed is what the ExecuteNonQuery method returns.

Reason is to have some value other than zero. General practice to have it short globally and long for long working scripts like parsers, crawlers, dumpers, exporting & importing scripts etc.

1. You can halt server, corrupt work of other people by memory consuming script without even knowing it.
2. You will not be seeing mistakes where something, let's say, infinite loop happened, and it will be harder to diagnose.
3. Such site may be easily DoSed by single user, when requesting pages with long execution time

Try adding -l to the nm flags in order to get the source of each symbol. If the library is compiled with debugging info (gcc -g) this should be the source file and line number. As Konrad said, the object file / static library is probably unknown at this point.

you can give :

select{
   position:absolute;
   top:50%;
   transform: translateY(-50%);
}

and to parent you have to give position:relative. it will work.

I had an issue with Page.ClientScript.RegisterStartUpScript - I wasn't using an update panel, but the control was cached. This meant that I had to insert the script into a Literal (or could use a PlaceHolder) so when rendered from the cache the script is included.

A similar solution might work for you.

Try rmtree() in shutil from the Python standard library

If you are using logging then thread names will be helpful. A thread factory helps with this:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.ThreadFactory;

public class Main {

    static Logger LOG = LoggerFactory.getLogger(Main.class);

    static class MyTask implements Runnable {
        public void run() {
            LOG.info("A pool thread is doing this task");
        }
    }

You could create a simple batch script to do this for you:

TYPE %1 | MORE /P >%1.1
MOVE %1.1 %1

Then run <batch script name> <FILE> and <FILE> will be instantly converted to DOS line endings.

The <pre> is used to define pre-formatted text.
The text within <pre> tag is displayed in a fixed-width font and it preserves both spaces and line breaks that are present in the text.
Here I'm printing a JSON FILE without <pre> tag and then with <pre> tag.

Use code as follows:

mylist <- lapply(pressure, function(i)read.xlsx(i,colNames = FALSE))#
mydata <- do.call('rbind',mylist)#

EDIT: using c++14, the best solution is very easy to write thanks to lambdas that can now have parameters of type auto. This is my current favorite solution

std::sort(v.begin(), v.end(), [](auto &left, auto &right) {
    return left.second < right.second;
});

Just use a custom comparator (it's an optional 3rd argument to std::sort)

struct sort_pred {
    bool operator()(const std::pair<int,int> &left, const std::pair<int,int> &right) {
        return left.second < right.second;
    }
};

std::sort(v.begin(), v.end(), sort_pred());

If you're using a C++11 compiler, you can write the same using lambdas:

std::sort(v.begin(), v.end(), [](const std::pair<int,int> &left, const std::pair<int,int> &right) {
    return left.second < right.second;
});

EDIT: in response to your edits to your question, here's some thoughts ... if you really wanna be creative and be able to reuse this concept a lot, just make a template:

template <class T1, class T2, class Pred = std::less<T2> >
struct sort_pair_second {
    bool operator()(const std::pair<T1,T2>&left, const std::pair<T1,T2>&right) {
        Pred p;
        return p(left.second, right.second);
    }
};

then you can do this too:

std::sort(v.begin(), v.end(), sort_pair_second<int, int>());

or even

std::sort(v.begin(), v.end(), sort_pair_second<int, int, std::greater<int> >());

Though to be honest, this is all a bit overkill, just write the 3 line function and be done with it :-P

Actually, there are no examples at all. Here is my working code. Recording is triggered by the user pressing a button on the navBar. The recording uses cd quality (44100 samples), stereo (2 channels) linear pcm. Beware: if you want to use a different format, especially an encoded one, make sure you fully understand how to set the AVAudioRecorder settings (read carefully the audio types documentation), otherwise you will never be able to initialize it correctly. One more thing. In the code, I am not showing how to handle metering data, but you can figure it out easily. Finally, note that the AVAudioRecorder method deleteRecording as of this writing crashes your application. This is why I am removing the recorded file through the File Manager. When recording is done, I save the recorded audio as NSData in the currently edited object using KVC.

This is about the best you can do:

if (!mail(...)) {
   // Reschedule for later try or panic appropriately!
}

http://php.net/manual/en/function.mail.php

mail() returns TRUE if the mail was successfully accepted for delivery, FALSE otherwise.

It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.

If you need to suppress warnings, you can use:

if (!@mail(...))

Be careful though about using the @ operator without appropriate checks as to whether something succeed or not.

If mail() errors are not suppressible (weird, but can't test it right now), you could:

a) turn off errors temporarily:

$errLevel = error_reporting(E_ALL ^ E_NOTICE);  // suppress NOTICEs
mail(...);
error_reporting($errLevel);  // restore old error levels

b) use a different mailer, as suggested by fire and Mike.

If mail() turns out to be too flaky and inflexible, I'd look into b). Turning off errors is making debugging harder and is generally ungood.

Funnily enough, adjusting the padding seems to do it.

.first{
  padding: 2vh;
}

.second{
  padding: 4vh;
}

    transform: rotate(135deg);
    -webkit-transform: rotate(135deg);
 }

May be a bit late but in my case i had to put the id in the 2nd anonymous object. This is because the 1st one is for route values i.e the return Url.

@using (Html.BeginForm("Login", "Account", new {  ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { id = "signupform", role = "form" }))

Hope this can help somebody :)

@ewomack has a great answer for C#, unless you don't need extra object values. In my case, I ended up using something similar to:

@Html.ActionLink("Delete", "DeleteList", "List", new object { },
new { @class = "delete"})

Quoting the spec

15.4 Array Objects

Array objects give special treatment to a certain class of property names. A property name P (in the form of a String value) is an array index if and only if ToString(ToUint32(P)) is equal to P and ToUint32(P) is not equal to 2^32-1. A property whose property name is an array index is also called an element. Every Array object has a length property whose value is always a nonnegative integer less than 2^32. The value of the length property is numerically greater than the name of every property whose name is an array index; whenever a property of an Array object is created or changed, other properties are adjusted as necessary to maintain this invariant. Specifically, whenever a property is added whose name is an array index, the length property is changed, if necessary, to be one more than the numeric value of that array index; and whenever the length property is changed, every property whose name is an array index whose value is not smaller than the new length is automatically deleted. This constraint applies only to own properties of an Array object and is unaffected by length or array index properties that may be inherited from its prototypes.

And here's a table for typeof

To add some background, there are two data types in JavaScript:

1. Primitive Data types - This includes null, undefined, string, boolean, number and object.
2. Derived data types/Special Objects - These include functions, arrays and regular expressions. And yes, these are all derived from "Object" in JavaScript.

An object in JavaScript is similar in structure to the associative array/dictionary seen in most object oriented languages - i.e., it has a set of key-value pairs.

An array can be considered to be an object with the following properties/keys:

1. Length - This can be 0 or above (non-negative).
2. The array indices. By this, I mean "0", "1", "2", etc are all properties of array object.

Hope this helped shed more light on why typeof Array returns an object. Cheers!

A DataFrame is defined well with a google search for "DataFrame definition":

A data frame is a table, or two-dimensional array-like structure, in which each column contains measurements on one variable, and each row contains one case.

So, a DataFrame has additional metadata due to its tabular format, which allows Spark to run certain optimizations on the finalized query.

An RDD, on the other hand, is merely a Resilient Distributed Dataset that is more of a blackbox of data that cannot be optimized as the operations that can be performed against it, are not as constrained.

However, you can go from a DataFrame to an RDD via its rdd method, and you can go from an RDD to a DataFrame (if the RDD is in a tabular format) via the toDF method

In general it is recommended to use a DataFrame where possible due to the built in query optimization.

In Windows 7+ the first quotations will be the title to the cmd window to open the program:

start "title" "C:\path\program.exe"

Formatting your command like the above will temporarily open a cmd window that goes away as fast as it comes up so you really never see it. It also allows you to open more than one program without waiting for the first one to close first.

Why do you need to state both x and y before the :?

Because it's a function definition and it needs to know what parameters the function accepts, and in what order. It can't just look at the expression and use the variables names in that, because some of those names you might want to use existing local or global variable values for, and even if it did that, it wouldn't know what order it should expect to get them.

Your error message means that Tk is calling your lambda with one argument, while your lambda is written to accept no arguments. If you don't need the argument, just accept one and don't use it. (Demosthenex has the code, I would have posted it but was beaten to it.)

As @JDlugosz points out in the comments, Herb gives other advice in another (later?) talk, see roughly from here: https://youtu.be/xnqTKD8uD64?t=54m50s.

His advice boils down to only using value parameters for a function f that takes so-called sink arguments, assuming you will move construct from these sink arguments.

This general approach only adds the overhead of a move constructor for both lvalue and rvalue arguments compared to an optimal implementation of f tailored to lvalue and rvalue arguments respectively. To see why this is the case, suppose f takes a value parameter, where T is some copy and move constructible type:

void f(T x) {
  T y{std::move(x)};
}

Calling f with an lvalue argument will result in a copy constructor being called to construct x, and a move constructor being called to construct y. On the other hand, calling f with an rvalue argument will cause a move constructor to be called to construct x, and another move constructor to be called to construct y.

In general, the optimal implementation of f for lvalue arguments is as follows:

void f(const T& x) {
  T y{x};
}

In this case, only one copy constructor is called to construct y. The optimal implementation of f for rvalue arguments is, again in general, as follows:

void f(T&& x) {
  T y{std::move(x)};
}

In this case, only one move constructor is called to construct y.

So a sensible compromise is to take a value parameter and have one extra move constructor call for either lvalue or rvalue arguments with respect to the optimal implementation, which is also the advice given in Herb's talk.

As @JDlugosz pointed out in the comments, passing by value only makes sense for functions that will construct some object from the sink argument. When you have a function f that copies its argument, the pass-by-value approach will have more overhead than a general pass-by-const-reference approach. The pass-by-value approach for a function f that retains a copy of its parameter will have the form:

void f(T x) {
  T y{...};
  ...
  y = std::move(x);
}

In this case, there is a copy construction and a move assignment for an lvalue argument, and a move construction and move assignment for an rvalue argument. The most optimal case for an lvalue argument is:

void f(const T& x) {
  T y{...};
  ...
  y = x;
}

This boils down to an assignment only, which is potentially much cheaper than the copy constructor plus move assignment required for the pass-by-value approach. The reason for this is that the assignment might reuse existing allocated memory in y, and therefore prevent (de)allocations, whereas the copy constructor will usually allocate memory.

For an rvalue argument the most optimal implementation for f that retains a copy has the form:

void f(T&& x) {
  T y{...};
  ...
  y = std::move(x);
}

So, only a move assignment in this case. Passing an rvalue to the version of f that takes a const reference only costs an assignment instead of a move assignment. So relatively speaking, the version of f taking a const reference in this case as the general implementation is preferable.

So in general, for the most optimal implementation, you will need to overload or do some kind of perfect forwarding as shown in the talk. The drawback is a combinatorial explosion in the number of overloads required, depending on the number of parameters for f in case you opt to overload on the value category of the argument. Perfect forwarding has the drawback that f becomes a template function, which prevents making it virtual, and results in significantly more complex code if you want to get it 100% right (see the talk for the gory details).

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

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

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

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

So for your example I would suggest something like:

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

Judging by the documentation for date/time functions, you should be able to do something like:

SELECT * FROM FOO
WHERE MY_DATE_FIELD >= NOW() - INTERVAL 1 DAY

David's answer is correct, but if it's still a little abstract, here are two examples:

1. You might want to zero all freed pointers to catch memory problems earlier. C-style you'd do:

   void freeAndZero(void** ptr)
   {
       free(*ptr);
       *ptr = 0;
   }
   
   void* ptr = malloc(...);
   
   ...
   
   freeAndZero(&ptr);
   

   In C++ to do the same, you might do:

   template<class T> void freeAndZero(T* &ptr)
   {
       delete ptr;
       ptr = 0;
   }
   
   int* ptr = new int;
   
   ...
   
   freeAndZero(ptr);
   

2. When dealing with linked-lists - often simply represented as pointers to a next node:

   struct Node
   {
       value_t value;
       Node* next;
   };
   

   In this case, when you insert to the empty list you necessarily must change the incoming pointer because the result is not the NULL pointer anymore. This is a case where you modify an external pointer from a function, so it would have a reference to pointer in its signature:

   void insert(Node* &list)
   {
       ...
       if(!list) list = new Node(...);
       ...
   }
   

There's an example in this question.

Create a symlink at /usr/bin named 'ruby' and point it to the latest installed ruby.

You can use something like ln -s /usr/bin/ruby /to/the/installed/ruby/binary

Hope this helps.

You cannot in the same page's loading set and check if cookies is set you must perform reload page:

#collect is actually an alias for #map. That means the two methods can be used interchangeably, and effect the same behavior.

Yes, you can use the *args (splat) syntax:

function_that_needs_strings(*my_list)

where my_list can be any iterable; Python will loop over the given object and use each element as a separate argument to the function.

See the call expression documentation.

There is a keyword-parameter equivalent as well, using two stars:

kwargs = {'foo': 'bar', 'spam': 'ham'}
f(**kwargs)

and there is equivalent syntax for specifying catch-all arguments in a function signature:

def func(*args, **kw):
    # args now holds positional arguments, kw keyword arguments

PySimpleGUI wraps tkinter and works on Python 3 and 2.7. It also runs on Qt, WxPython and in a web browser, using the same source code for all platforms.

You can make custom GUIs that utilize all of the same widgets that you find in tkinter (sliders, checkboxes, radio buttons, ...). The code tends to be very compact and readable.

#!/usr/bin/env python
import sys
if sys.version_info[0] >= 3:
    import PySimpleGUI as sg
else:
    import PySimpleGUI27 as sg

layout = [[ sg.Text('My Window') ],
          [ sg.Button('OK')]]

window = sg.Window('My window').Layout(layout)
button, value = window.Read()

As explained in the PySimpleGUI Documentation, to build the .EXE file you run:

pyinstaller -wF MyGUIProgram.py

Call Application.DoEvents() after setting the label, but you should do all the work in a separate thread instead, so the user may close the window.

Remote pick directory path should be the exact path on the ftp server you are tryng to access.. here is the script to download files from the server.. you can add or modify with SSLMode..

#ftp server 
$ftp = "ftp://example.com/" 
$user = "XX" 
$pass = "XXX"
$SetType = "bin"  
$remotePickupDir = Get-ChildItem 'c:\test' -recurse
$webclient = New-Object System.Net.WebClient 

$webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)  
foreach($item in $remotePickupDir){ 
    $uri = New-Object System.Uri($ftp+$item.Name) 
    #$webclient.UploadFile($uri,$item.FullName)
    $webclient.DownloadFile($uri,$item.FullName)
}

Suppose you have

<body>
  <div id="root" />
</body>

With normal CSS, you can do the following. See a working app https://github.com/onmyway133/Lyrics/blob/master/index.html

#root {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
}

With flexbox, you can

html, body {
  height: 100%
}
body {
  display: flex;
  align-items: stretch;
}

#root {
  width: 100%
}

You can use the ansible.cfg file, it should look like this (There are other parameters which you might want to include):

[defaults]
inventory = <PATH TO INVENTORY FILE>
remote_user = <YOUR USER>
private_key_file =  <PATH TO KEY_FILE>

Hope this saves you some typing

You might also consider adding ".

For example for %i in (*.wav) do opusenc "%~ni.wav" "%~ni.opus" is very good idea.

HttpClient is a new API that came with 4.3, it has updated API's with support for progress events, json deserialization by default, Interceptors and many other great features. See more here https://angular.io/guide/http

Http is the older API and will eventually be deprecated.

Since their usage is very similar for basic tasks I would advise using HttpClient since it is the more modern and easy to use alternative.

Probably you have a sub asp.net project folder within the project folder which is not configured as virtual directory. Setup the project to run in IIS.

Oh My Goodness! Look at the size of my temporary table space! Or... how to shrink temporary tablespaces in Oracle.

Yes I ran a query to see how big my temporary tablespace is:

SQL> SELECT tablespace_name, file_name, bytes
2  FROM dba_temp_files WHERE tablespace_name like 'TEMP%';

TABLESPACE_NAME   FILE_NAME                                 BYTES
----------------- -------------------------------- --------------
TEMP              /the/full/path/to/temp01.dbf     13,917,200,000

The first question you have to ask is why the temporary tablespace is so large. You may know the answer to this off the top of your head. It may be due to a large query that you just run with a sort that was a mistake (I have done that more than once.) It may be due to some other exceptional circumstance. If that is the case then all you need to do to clean up is to shrink the temporary tablespace and move on in life.

But what if you don't know? Before you decide to shrink you may need to do some investigation into the causes of the large tablespace. If this happens on a regular basis then it is possible that your database just needs that much space.

The dynamic performance view

V$TEMPSEG_USAGE

can be very useful in determining the cause.

Maybe you just don't care about the cause and you just need to shrink it. This is your third day on the job. The data in the database is only 200MiB if data and the temporary tablespace is 13GiB - Just shrink it and move on. If it grows again then we will look into the cause. In the mean time I am out of space on that disk volume and I just need the space back.

Let's take a look at shrinking it. It will depend a little on what version of Oracle you are running and how the temporary tablespace was set up.
Oracle will do it's best to keep you from making any horrendous mistakes so we will just try the commands and if they don't work we will shrink in a new way.

First let's try to shrink the datafile. If we can do that then we get back the space and we can worry about why it grew tomorrow.

SQL>
SQL> alter database tempfile '/the/full/path/to/temp01.dbf' resize 256M; 
alter database tempfile '/the/full/path/to/temp01.dbf' resize 256M
*   
ERROR at line 1:
ORA-03297: file contains used data beyond requested RESIZE value

Depending on the error message you may want to try this with different sizes that are smaller than the current site of the file. I have had limited success with this. Oracle will only shrink the file if the temporary tablespace is at the head of the file and if it is smaller than the size you specify. Some old Oracle documentation (they corrected this) said that you could issue the command and the error message would tell you what size you could shrink to. By the time I started working as a DBA this was not true. You just had to guess and re-run the command a bunch of times and see if it worked.

Alright. That didn't work. How about this.

SQL> alter tablespace YOUR_TEMP_TABLESPACE_NAME shrink space keep 256M;

If you are in 11g (Maybee in 10g too) this is it! If it works you may want to go back to the previous command and give it some more tries.

But what if that fails. If the temporary tablespace is the default temporary that was set up when the database was installed then you may need to do a lot more work. At this point I usually re-evaluate if I really need that space back. After all disk space only costs $X.XX a GiB. Usually I don't want to make changes like this during production hours. That means working at 2AM AGAIN! (Not that I really object to working at 2AM - it is just that... Well I like to sleep too. And my wife likes to have me at home at 2AM... not roaming the downtown streets at 4AM trying to remember where I parked my car 3 hours earlier. I have heard of that "telecommuting" thing. I just worry that I will get half way through and then my internet connectivity will fail - then I have to rush downtown to fix it all before folks show up in the morning to use the database.)

Ok... Back to the serious stuff... If the temporary tablespace you want to shrink is your default temporary tablespace, you will have to first create a new temporary tablespace, set it as the default temporary tablespace then drop your old default temporary tablespace and recreate it. Afterwords drop the second temporary table created.

SQL> CREATE TEMPORARY TABLESPACE temp2
2  TEMPFILE '/the/full/path/to/temp2_01.dbf' SIZE 5M REUSE
3  AUTOEXTEND ON NEXT 1M MAXSIZE unlimited
4  EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;

Tablespace created.

SQL> ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp2;

Database altered.

SQL> DROP TABLESPACE temp INCLUDING CONTENTS AND DATAFILES;

Tablespace dropped.


SQL> CREATE TEMPORARY TABLESPACE temp
2  TEMPFILE '/the/full/path/to/temp01.dbf' SIZE 256M REUSE
3  AUTOEXTEND ON NEXT 128M MAXSIZE unlimited
4  EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;

Tablespace created.

SQL> ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp;

Database altered.

SQL> DROP TABLESPACE temp2 INCLUDING CONTENTS AND DATAFILES;

Tablespace dropped.

Hopefully one of these things will help!

For caching, I would use OkHttp interceptors to gain control over caching policy. Check out this sample that's included in the OkHttp library.

RewriteResponseCacheControl.java

Here's how I'd use it with Picasso -

OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.networkInterceptors().add(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Response originalResponse = chain.proceed(chain.request());
            return originalResponse.newBuilder().header("Cache-Control", "max-age=" + (60 * 60 * 24 * 365)).build();
        }
    });

    okHttpClient.setCache(new Cache(mainActivity.getCacheDir(), Integer.MAX_VALUE));
    OkHttpDownloader okHttpDownloader = new OkHttpDownloader(okHttpClient);
    Picasso picasso = new Picasso.Builder(mainActivity).downloader(okHttpDownloader).build();
    picasso.load(imageURL).into(viewHolder.image);

if file name contains directory and you need to not lose directory:

fileName.Remove(fileName.LastIndexOf("."))

java_home environment variable should point to the location of the proper version of java installation directory, so that tomcat starts with the right version. for example it you built the project with java 1.7 , then make sure that JAVA_HOME environment variable points to the jdk 1.7 installation directory in your machine.

I had same problem , when i deploy the war in tomcat and run, the link throws the error. But pointing the variable - JAVA_HOME to jdk 1.7 resolved the issue, as my war file was built in java 1.7 environment.

Try command + t. It works for me.

Position the cursor inside the class, then press ALT + Ins and select Getters and Setters from the contextual menu.

CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

The leading ', ' and trailing ',' are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).

That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.

In addition: don't use 'single quotes' as identifier delimiters; this syntax is deprecated. Use [square brackets] (preferred) or "double quotes" if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx

EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE syntax variant or by using something like IN()):

CASE 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

If you have more values, it might be worthwhile to use a split function, e.g.

USE tempdb;
GO

CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
   RETURN ( SELECT DISTINCT Item FROM
       ( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
         FROM ( SELECT [XML] = CONVERT(XML, '<i>'
         + REPLACE(@List,',', '</i><i>') + '</i>').query('.')
           ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
       WHERE Item IS NOT NULL
   );
GO

CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO

INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');

SELECT t.ID
  FROM dbo.[Table] AS t
  INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
  ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
  GROUP BY t.ID;
GO

Results:

ID
----
1

4

To add to what others posted:

ExecuteScalar conceptually returns the leftmost column from the first row of the resultset from the query; you could ExecuteScalar a SELECT * FROM staff, but you'd only get the first cell of the resulting rows Typically used for queries that return a single value. I'm not 100% sure about SQLServer but in Oracle, you wouldnt use it to run a FUNCTION (a database code that returns a single value) and expect it to give you the return value of the function even though functions return single values.. However, if youre running the function as part of a query, e.g. SELECT SUBSTR('abc', 1, 1) FROM DUAL then it would give the return value by virtue of the fact that the return value is stored in the top leftmost cell of the resulting rowset

ExecuteNonQuery would be used to run database stored procedures, functions and queries that modify data (INSERT/UPDATE/DELETE) or modify database structure (CREATE TABLE...). Typically the return value of the call is an indication of how many rows were affected by the operation but check the DB documentation to guarantee this

For unsigned data type there is no sign bit and all bits are for data ; whereas for signed data type MSB is indicated sign bit and remaining bits are for data.

To find the range do following things :

Step:1 -> Find out no of bytes for the give data type.

Step:2 -> Apply following calculations.

      Let n = no of bits in data type  

      For signed data type ::
            Lower Range = -(2^(n-1)) 
            Upper Range = (2^(n-1)) - 1)  

      For unsigned data type ::
            Lower Range = 0 
            Upper Range = (2^(n)) - 1 

For e.g.

For unsigned int size = 4 bytes (32 bits) --> Range [0 , (2^(32)) - 1]

For signed int size = 4 bytes (32 bits) --> Range [-(2^(32-1)) , (2^(32-1)) - 1]

Try

sed 'NUMq;d'  /etc/*release | awk {'print $1}'

where NUM is line number

ex. sed '1q;d'  /etc/*release | awk {'print $1}'

if you use isset like the answer posted already by singles, just make sure there is a bracket at the end like so:
$query_age = (isset($_GET['query_age']) ? $_GET['query_age'] : null);

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

Maybe a simple loop for chars to replace:

a = '&#'

to_replace = ['&', '#']

for char in to_replace:
    a = a.replace(char, "\\"+char)

print(a)

>>> \&\#

Here is another neat trick to define enum using X Macro:

#include <iostream>

#define WEEK_DAYS \
X(MON, "Monday", true) \
X(TUE, "Tuesday", true) \
X(WED, "Wednesday", true) \
X(THU, "Thursday", true) \
X(FRI, "Friday", true) \
X(SAT, "Saturday", false) \
X(SUN, "Sunday", false)

#define X(day, name, workday) day,
enum WeekDay : size_t
{
    WEEK_DAYS
};
#undef X

#define X(day, name, workday) name,
char const *weekday_name[] =
{
    WEEK_DAYS
};
#undef X

#define X(day, name, workday) workday,
bool weekday_workday[]
{
    WEEK_DAYS
};
#undef X

int main()
{
    std::cout << "Enum value: " << WeekDay::THU << std::endl;
    std::cout << "Name string: " << weekday_name[WeekDay::THU] << std::endl;
    std::cout << std::boolalpha << "Work day: " << weekday_workday[WeekDay::THU] << std::endl;

    WeekDay wd = SUN;
    std::cout << "Enum value: " << wd << std::endl;
    std::cout << "Name string: " << weekday_name[wd] << std::endl;
    std::cout << std::boolalpha << "Work day: " << weekday_workday[wd] << std::endl;

    return 0;
}

Live Demo: https://ideone.com/bPAVTM

Outputs:

Enum value: 3
Name string: Thursday
Work day: true
Enum value: 6
Name string: Sunday
Work day: false

Use int64_t, that portable C99 code.

int64_t var = 0x0000444400004444LL;

For printing:

#define __STDC_FORMAT_MACROS
#include <inttypes.h>

printf("blabla %" PRIi64 " blabla\n", var);

Please check that your class and namespace name is the same...

It happens when the namespace and class name are the same. do one thing write the full name of the namespace when you want to use the namespace.

using Student.Models.Db;

namespace Student.Controllers
{
    public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index()
        {
            List<Student> student = null;
            return View();
        }
    }

The first case is telling the web server that you are posting JSON data as in:

{ Name : 'John Smith', Age: 23}

The second option is telling the web server that you will be encoding the parameters in the URL as in:

Name=John+Smith&Age=23

Your percentage divided by 100 (to get the percentage between 0 and 1) times by the number

35.8/100*10000

As well as the suggestions for \c and ignorecase, I find the smartcase very useful. If you search for something containing uppercase characters, it will do a case sensitive search; if you search for something purely lowercase, it will do a case insensitive search. You can use \c and \C to override this:

:set ignorecase
:set smartcase
/copyright      " Case insensitive
/Copyright      " Case sensitive
/copyright\C    " Case sensitive
/Copyright\c    " Case insensitive

See:

:help /\c
:help /\C
:help 'smartcase'

You can use the col element as specified in HTML 4.0 (link). It works in every browser. You can give it an ID or a class or an inline style. only caveat is that it affects the whole column across all rows. Example:

<table>
    <col />
    <col width="50" />
    <col id="anId" />
    <col class="whatever" />
    <col style="border:1px solid #000;" />
    <tbody>
        <tr>
            <td>One</td>
            <td>Two</td>
            <td>Three</td>
            <td>Four</td>
            <td>Five</td>
        </tr>
    </tbody>
</table>

The game was Robowar--I used to play a bit back in college. Here's the wiki for it. I guess it's now open source and available on windows.

It obtains a reference to the class object with the FQCN (fully qualified class name) oracle.jdbc.driver.OracleDriver.

It doesn't "do" anything in terms of connecting to a database, aside from ensure that the specified class is loaded by the current classloader. There is no fundamental difference between writing

Class<?> driverClass = Class.forName("oracle.jdbc.driver.OracleDriver");
// and
Class<?> stringClass = Class.forName("java.lang.String");

Class.forName("com.example.some.jdbc.driver") calls show up in legacy code that uses JDBC because that is the legacy way of loading a JDBC driver.

From The Java Tutorial:

In previous versions of JDBC, to obtain a connection, you first had to initialize your JDBC driver by calling the method Class.forName. This methods required an object of type java.sql.Driver. Each JDBC driver contains one or more classes that implements the interface java.sql.Driver.
...
Any JDBC 4.0 drivers that are found in your class path are automatically loaded. (However, you must manually load any drivers prior to JDBC 4.0 with the method Class.forName.)

Further reading _{^{(read: questions this is a dup of)}}

• What purpose does Class.forName() serve if you don't use the return value?
• How does Class.forName() work?
• What does 'Class.forName("org.sqlite.JDBC");' do?
• What is the purpose of 'Class.forName("MY_JDBC_DRIVER")'?
• Loading JDBC driver

It's all really just basic uses of Factorization and Square Roots.

It may appear to be abstract, but in reality it simply lies with the fact that a non-prime-number's maximum possible factorial would have to be its square root because:

sqrroot(n) * sqrroot(n) = n.

Given that, if any whole number above 1 and below or up to sqrroot(n) divides evenly into n, then n cannot be a prime number.

Pseudo-code example:

i = 2;

is_prime = true;

while loop (i <= sqrroot(n))
{
  if (n % i == 0)
  {
    is_prime = false;
    exit while;
  }
  ++i;
}

You can make the whole script a function like this:

main_function() {
  do_things_here
}

then at the end of the script have this:

if [ -z $TERM ]; then
  # if not run via terminal, log everything into a log file
  main_function 2>&1 >> /var/log/my_uber_script.log
else
  # run via terminal, only output to screen
  main_function
fi

Alternatively, you may log everything into logfile each run and still output it to stdout by simply doing:

# log everything, but also output to stdout
main_function 2>&1 | tee -a /var/log/my_uber_script.log

To create a view controller:

UIViewController * vc = [[UIViewController alloc] init];

To call a view controller (must be called from within another viewcontroller):

[self presentViewController:vc animated:YES completion:nil];

For one, use nil rather than null.

Loading a view controller from the storyboard:

NSString * storyboardName = @"MainStoryboard"; 
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:@"IDENTIFIER_OF_YOUR_VIEWCONTROLLER"];
[self presentViewController:vc animated:YES completion:nil];

Identifier of your view controller is either equal to the class name of your view controller, or a Storyboard ID that you can assign in the identity inspector of your storyboard.

Yes, the 3rd template parameter on map specifies the comparator, which is a binary predicate. Example:

struct ByLength : public std::binary_function<string, string, bool>
{
    bool operator()(const string& lhs, const string& rhs) const
    {
        return lhs.length() < rhs.length();
    }
};

int main()
{
    typedef map<string, string, ByLength> lenmap;
    lenmap mymap;

    mymap["one"] = "one";
    mymap["a"] = "a";
    mymap["fewbahr"] = "foobar";

    for( lenmap::const_iterator it = mymap.begin(), end = mymap.end(); it != end; ++it )
        cout << it->first << "\n";
}

The specific format is:

git commit --author="John Doe <[email protected]>" -m "Impersonation is evil." 

Another possible solution is to use a Scanner object like this:

Scanner scanner = new Scanner(inputString);  
if (scanner.hasNextInt()) {  
  return true;
}
else {
  return false
}

Of course, if you are looking for a double, use hasNextDouble() method (see: Scanner javadoc)

You mean this?

from string import punctuation, digits

takeout = punctuation + digits

turnthis = "(fjskl) 234 = -345 089 abcdef"
turnthis = turnthis.translate(None, takeout)[::-1]
print turnthis

Library makefiles, which are generated by autotools (the ./configure you have to issue) often have a verbose option, so basically, using make VERBOSE=1 or make V=1 should give you the full commands.

But this depends on how the makefile was generated.

The -d option might help, but it will give you an extremely long output.

You can try this click event

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex >= 0)
    {
        DataGridViewRow row = this.dataGridView1.Rows[e.RowIndex];
        Eid_txt.Text = row.Cells["Employee ID"].Value.ToString();
        Name_txt.Text = row.Cells["First Name"].Value.ToString();
        Surname_txt.Text = row.Cells["Last Name"].Value.ToString();

This is how I did it. In config.php

$config['HTML_TITLE'] = "SO TITLE test";

In applications/view/header.php (assuming html code)

<title><?=$this->config->item("HTML_TITLE");?> </title>

Here is a minimal example using moviepy. For me this was the easiest solution.

import os
import moviepy.video.io.ImageSequenceClip
image_folder='folder_with_images'
fps=1

image_files = [image_folder+'/'+img for img in os.listdir(image_folder) if img.endswith(".png")]
clip = moviepy.video.io.ImageSequenceClip.ImageSequenceClip(image_files, fps=fps)
clip.write_videofile('my_video.mp4')

Loading url with SwipeRefreshLayout and ProgressBar:

UrlPageActivity.java:

    WebView webView;
    SwipeRefreshLayout _swipe_procesbar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_url_page);


        String url = "http://stackoverflow.com/";

        _swipe_procesbar = (SwipeRefreshLayout)findViewById(R.id.url_path_swipe_procesbar);

        _swipe_procesbar.post(new Runnable() {
                                  @Override
                                  public void run() {
                                      _swipe_procesbar.setRefreshing(true);
                                  }
                              }
        );

        webView = (WebView) findViewById(R.id.url_page_web_view);
        webView.getSettings().setJavaScriptEnabled(true);

        webView.setWebViewClient(new WebViewClient() {
            public void onPageFinished(WebView view, String url) {
                _swipe_procesbar.setRefreshing(false);
                _swipe_procesbar.setEnabled(false);
            }
        });
        webView.loadUrl(url);
    }

activity_url_page.xml:

You can use display: inline-block.

The date can be converted in typescript to this format 'yyyy-MM-dd' by using Datepipe

import { DatePipe } from '@angular/common'
...
constructor(public datepipe: DatePipe){}
...
myFunction(){
 this.date=new Date();
 let latest_date =this.datepipe.transform(this.date, 'yyyy-MM-dd');
}

and just add Datepipe in 'providers' array of app.module.ts. Like this:

import { DatePipe } from '@angular/common'
...
providers: [DatePipe]

Another option is to use multer, which uses busboy under the hood, but is simpler to set up.

var multer = require('multer');

Use multer and set the destination for the upload:

app.use(multer({dest:'./uploads/'}));

Create a form in your view, enctype='multipart/form-data is required for multer to work:

form(role="form", action="/", method="post", enctype="multipart/form-data")
    div(class="form-group")
        label Upload File
        input(type="file", name="myfile", id="myfile")

Then in your POST you can access the data about the file:

app.post('/', function(req, res) {
  console.dir(req.files);
});

A full tutorial on this can be found here.
