CREATE TABLE some_table (
  field1 int(11) NOT NULL AUTO_INCREMENT,
  field2 varchar(10) NOT NULL,
  field3 varchar(10) NOT NULL,
  PRIMARY KEY (`field1`)
);

INSERT INTO `some_table` (field1, field2, field3) VALUES
(1, 'text one', 'foo'),
(2, 'text two', 'bar'),
(3, 'text three', 'data'),
(4, 'text four', 'magic');

This query is a bit strange but it does not need another query to initialize the variable; and it can be embedded in a more complex query. It returns all the 'field2's separated by a semicolon.

SELECT result
FROM   (SELECT @result := '',
               (SELECT result
                FROM   (SELECT @result := CONCAT_WS(';', @result, field2) AS result,
                               LENGTH(@result)                            AS blength
                        FROM   some_table
                        ORDER  BY blength DESC
                        LIMIT  1) AS sub1) AS result) AS sub2; 

DISCLAIMER: this solution is not using Header.

If someone is looking for a lazy-lazy manner (also in WebApi), I'd suggest:

public YourResult Authorize([FromBody]BasicAuthCredentials credentials)

You are not getting from header, but at least you have an easy alternative. You can always check the object for null and fallback to header mechanism.

Another way is to use toLocaleDateString with a locale that has a big-endian date format standard, such as Sweden, Lithuania, Hungary, South Korea, ...:

date.toLocaleDateString('se')

To remove the delimiters (-) is just a matter of replacing the non-digits:

console.log( new Date().toLocaleDateString('se').replace(/\D/g, '') );

This does not have the potential error you can get with UTC date formats: the UTC date may be one day off compared to the date in the local time zone.

$('html').keyup(function(e){
    if(e.keyCode == 46) {
        alert('Delete key released');
    }
});

In SQL Developer, from the top menu choose Tools > Data Export. This launches the Data Export wizard. It's pretty straightforward from there.

There is a tutorial on the OTN site. Find it here.

For Swift:

AVPlayer:

let player = AVPlayer(URL: NSURL(string: "http://www.sample.com/movie.mov"))
if (player.rate != 0 && player.error == nil) {
   println("playing")
}

Update:
player.rate > 0 condition changed to player.rate != 0 because if video is playing in reverse it can be negative thanks to Julian for pointing out.
Note: This might look same as above(Maz's) answer but in Swift '!player.error' was giving me a compiler error so you have to check for error using 'player.error == nil' in Swift.(because error property is not of 'Bool' type)

AVAudioPlayer:

if let theAudioPlayer =  appDelegate.audioPlayer {
   if (theAudioPlayer.playing) {
       // playing
   }
}

AVQueuePlayer:

if let theAudioQueuePlayer =  appDelegate.audioPlayerQueue {
   if (theAudioQueuePlayer.rate != 0 && theAudioQueuePlayer.error == nil) {
       // playing
   }
}

'1.0-0' will give you zero decimal places i.e. no decimals. e.g.$500

The performance should be identical, but I would suggest using the join-version due to improved clarity when it comes to outer joins.

Also unintentional cartesian products can be avoided using the join-version.

A third effect is an easier to read SQL with a simpler WHERE-condition.

Check this link in MDN

let x = 1;

if (x === 1) {
let x = 2;

console.log(x);
// expected output: 2
}

console.log(x);
// expected output: 1

$.extend(true, [], [['a', ['c']], 'b'])

That should do it for you.

Just another way to do this:

=MID(A1, LEN(A1), 1)

Do not under any circumstances disable the constraints. This is an extremely stupid practice. You cannot maintain data integrity if you do things like this. Data integrity is the first consideration of a database because without it, you have nothing.

The correct method is to delete from the child tables before trying to delete the parent record. You are probably timing out because you have set up cascading deltes which is another bad practice in a large database.

If you want to include some options besides regional localization, you have to use $.extend, like this:

$(function() {
   $('#Date').datepicker($.extend({
      showMonthAfterYear: false,
      dateFormat:'d MM, y'
    },
    $.datepicker.regional['fr']
  ));
});

An object file is the real output from the compilation phase. It's mostly machine code, but has info that allows a linker to see what symbols are in it as well as symbols it requires in order to work. (For reference, "symbols" are basically names of global objects, functions, etc.)

A linker takes all these object files and combines them to form one executable (assuming that it can, ie: that there aren't any duplicate or undefined symbols). A lot of compilers will do this for you (read: they run the linker on their own) if you don't tell them to "just compile" using command-line options. (-c is a common "just compile; don't link" option.)

Use this:

<asp:CustomValidator runat="server" id="vld" ValidateEmptyText="true"/>

To validate an empty field.

You don't need to add 2 validators !

I recently ran into this problem while trying to do a manual install of texane's open-source STLink utility on Ubuntu. The solution was, oddly enough,

make clean
make

fixed my agent string evaluation by scrubbing the string for LOWERCASE "iphone os 5_0" as opposed to "iPhone OS 5_0." now i am properly assigning iOS 5 specific classes to my html, when the uppercase scrub failed.

I have used this and it seems to work with outlook, not using html but you can format the text with line breaks at least when the body is added as output.

<a href="mailto:[email protected]?subject=Hello world&body=Line one%0DLine two">Email me</a>

I would like to re-emphasize the following:

• You might have added the SSH key to your repository (e.g. ExampleRepo), but this is NOT where the SSH key goes.
• It is meant to go into YOUR PROFILE. This is the small avatar on the bottom left corner of the screen. Here, you'll find a different place to put your SSH Keys (under Security) > then you add the key here instead.
• If you accidentally put your SSH key into the repository (as opposed to your account), then delete the one in the repository.

Took me ages to realise, somehow even after reading the answers here it didn't click.

The example below is an adaptation and simplification of a longer post from We ? Swift. This is what it will look like:

Create a New Project

It can be just the usual Single View Application.

Add the Code

Replace the ViewController.swift code with the following:

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    
    // Data model: These strings will be the data for the table view cells
    let animals: [String] = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
    
    // cell reuse id (cells that scroll out of view can be reused)
    let cellReuseIdentifier = "cell"
    
    // don't forget to hook this up from the storyboard
    @IBOutlet var tableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Register the table view cell class and its reuse id
        self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)
        
        // (optional) include this line if you want to remove the extra empty cell divider lines
        // self.tableView.tableFooterView = UIView()

        // This view controller itself will provide the delegate methods and row data for the table view.
        tableView.delegate = self
        tableView.dataSource = self
    }
    
    // number of rows in table view
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.animals.count
    }
    
    // create a cell for each table view row
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        // create a new cell if needed or reuse an old one
        let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!
        
        // set the text from the data model
        cell.textLabel?.text = self.animals[indexPath.row]
        
        return cell
    }
    
    // method to run when table view cell is tapped
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }
}

Read the in-code comments to see what is happening. The highlights are

• The view controller adopts the UITableViewDelegate and UITableViewDataSource protocols.
• The numberOfRowsInSection method determines how many rows there will be in the table view.
• The cellForRowAtIndexPath method sets up each row.
• The didSelectRowAtIndexPath method is called every time a row is tapped.

Add a Table View to the Storyboard

Drag a UITableView onto your View Controller. Use auto layout to pin the four sides.

Hook up the Outlets

Control drag from the Table View in IB to the tableView outlet in the code.

Finished

That's all. You should be able run your app now.

This answer was tested with Xcode 9 and Swift 4

Variations

Row Deletion

You only have to add a single method to the basic project above if you want to enable users to delete rows. See this basic example to learn how.

Row Spacing

If you would like to have spacing between your rows, see this supplemental example.

Custom cells

The default layout for the table view cells may not be what you need. Check out this example to help get you started making your own custom cells.

Dynamic Cell Height

Sometimes you don't want every cell to be the same height. Starting with iOS 8 it is easy to automatically set the height depending on the cell content. See this example for everything you need to get you started.

IMO the nicest way is to use the next() function:

router.get('/', function(req, res, next) {
    var err = new Error('Not found');
    err.status = 404;
    return next(err);
}

Then the error is handled by your error handler and you can style the error nicely using HTML.

in API 22 they become deprecated and in API 23 they removed them completely, a simple workaround if you don't need all the fancy stuff from the new additions is to simply use the .jar files from apache that were integrated before API 22, but as separated .jar files:

1. http://hc.apache.org/downloads.cgi
2. download httpclient 4.5.1, the zile file
3. unzip all files
4. drag in your project httpclient-4.5.1.jar, httpcore-4.4.3.jar and httpmime-4.5.1.jar
5. project, right click, open module settings, app, dependencies, +, File dependency and add the 3 files
6. now everything should compile properly

You need to subscribe to the KeyDown event on the text box. Then something like this:

private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
    if (!char.IsControl(e.KeyChar) 
       && !char.IsDigit(e.KeyChar) 
       && e.KeyChar != '.' && e.KeyChar != '+' && e.KeyChar != '-'
       && e.KeyChar != '(' && e.KeyChar != ')' && e.KeyChar != '*' 
       && e.KeyChar != '/')
    {
        e.Handled = true;
        return;
    }
    e.Handled=false;
    return;
}

The important thing to know is that if you changed the Handled property to true, it will not process the keystroke. Setting it to false will.

I found this question whilst looking for exactly what you asked. Unfortunately you have accepted an incorrect answer. For the sake of other people who are trying to achieve what we were trying to achieve, I thought I'd post the correct answer.

$cur_cat = get_cat_ID( single_cat_title("",false) );

As you said single_term_title("", false); was correctly returning the category title, I'm not sure why you would have had troubles with your code; but the above code works flawlessly for me.

I had the same problem for days until I noticed (how could I look at it and not read the code :-(..) that config.inc.php is calling config-db.php

** MySql Server version: 5.7.5-m15
** Apache/2.4.10 (Ubuntu)
** phpMyAdmin 4.2.9.1deb0.1

/etc/phpmyadmin/config-db.php:

$dbuser='yourDBUserName';
$dbpass='';
$basepath='';
$dbname='phpMyAdminDBName';
$dbserver='';
$dbport='';
$dbtype='mysql';

Here you need to define your username, password, dbname and others that are showing empty' use default unless you changed their configuration. That solved the issue for me.
U hope it helps you.

Another option is to use Descendant selectors

HTML:

<div class="social">
<p class="first">burrito</p>
<p class="last">chimichanga</p>
</div>

Reference first one in CSS: .social .first { color: blue; }

Reference last one in CSS: .social .last { color: green; }

Jsfiddle: https://jsfiddle.net/covbtpaq/153/

On many source packages (e.g. for most GNU software), the building system may know about the DESTDIR make variable, so you can often do:

 make install DESTDIR=/tmp/myinst/
 sudo cp -va /tmp/myinst/ /

The advantage of this approach is that make install don't need to run as root, so you cannot end up with files compiled as root (or root-owned files in your build tree).

try following

try {
            String[] command = {"cmd.exe", "/C", "Start", "D:\\test.bat"};
            Process p =  Runtime.getRuntime().exec(command);           
        } catch (IOException ex) {
        }

Server Objects---> linked server ---> new linked server

In linked server write server name or IP address for other server and choose SQL Server In Security select (be made using this security context ) Write login and password for other server

Now connected then use

Select * from [server name or ip addresses ].databasename.dbo.tblname

Declaration

A prototype for a function which takes a function parameter looks like the following:

void func ( void (*f)(int) );

This states that the parameter f will be a pointer to a function which has a void return type and which takes a single int parameter. The following function (print) is an example of a function which could be passed to func as a parameter because it is the proper type:

void print ( int x ) {
  printf("%d\n", x);
}

Function Call

When calling a function with a function parameter, the value passed must be a pointer to a function. Use the function's name (without parentheses) for this:

func(print);

would call func, passing the print function to it.

Function Body

As with any parameter, func can now use the parameter's name in the function body to access the value of the parameter. Let's say that func will apply the function it is passed to the numbers 0-4. Consider, first, what the loop would look like to call print directly:

for ( int ctr = 0 ; ctr < 5 ; ctr++ ) {
  print(ctr);
}

Since func's parameter declaration says that f is the name for a pointer to the desired function, we recall first that if f is a pointer then *f is the thing that f points to (i.e. the function print in this case). As a result, just replace every occurrence of print in the loop above with *f:

void func ( void (*f)(int) ) {
  for ( int ctr = 0 ; ctr < 5 ; ctr++ ) {
    (*f)(ctr);
  }
}

If anyone came to this question looking for ways to add multiple parameters at the same time (my case), you can use .params with a MultivalueMap instead of adding each .param :

LinkedMultiValueMap<String, String> requestParams = new LinkedMultiValueMap<>()
requestParams.add("id", "1");
requestParams.add("name", "john");
requestParams.add("age", "30");

mockMvc.perform(get("my/endpoint").params(requestParams)).andExpect(status().isOk())

An improvement on var dict = {} is to use var dict = Object.create(null).

This will create an empty object that does not have Object.prototype as it's prototype.

var dict1 = {};
if (dict1["toString"]){
    console.log("Hey, I didn't put that there!")
}
var dict2 = Object.create(null);
if (dict2["toString"]){
    console.log("This line won't run :)")
}

& <-- verifies both operands
&& <-- stops evaluating if the first operand evaluates to false since the result will be false

(x != 0) & (1/x > 1) <-- this means evaluate (x != 0) then evaluate (1/x > 1) then do the &. the problem is that for x=0 this will throw an exception.

(x != 0) && (1/x > 1) <-- this means evaluate (x != 0) and only if this is true then evaluate (1/x > 1) so if you have x=0 then this is perfectly safe and won't throw any exception if (x != 0) evaluates to false the whole thing directly evaluates to false without evaluating the (1/x > 1).

EDIT:

exprA | exprB <-- this means evaluate exprA then evaluate exprB then do the |.

exprA || exprB <-- this means evaluate exprA and only if this is false then evaluate exprB and do the ||.

This is more a footnote to a number of the answers above which suggest the use of ON DUPLICATE KEY UPDATE, BEWARE that this is NOT always replication safe, so if you ever plan on growing beyond a single server, you'll want to avoid this and use two queries, one to verify the existence, and then a second to either UPDATE when a row exists, or INSERT when it does not.

well, I actually just saved and closed the project and restarted VS Express 2013 in windows 8 and that sorted my problem.

If you are trying to test your app coded in android studio through your android phone, its generally the issue of your phone. Just uncheck all the USB debugging options and toggle the developer options to OFF. Then restart your phone and switch the developer and USB debugging on. You are ready to go!

The display:table family of CSS properties is mostly there so that HTML tables can be defined in terms of them. Because they're so intimately linked to a specific tag structure, they don't see much use beyond that.

If you were going to use these properties in your page, you would need a tag structure that closely mimicked that of tables, even though you weren't actually using the <table> family of tags. A minimal version would be a single container element (display:table), with direct children that can all be represented as rows (display:table-row), which themselves have direct children that can all be represented as cells (display:table-cell). There are other properties that let you mimic other tags in the table family, but they require analogous structures in the HTML. Without this, it's going to be very hard (if not impossible) to make good use of these properties.

By default a tiny JavaScript server called "Metro Server" runs on the port 8081.

You need to make this port available for this Server to start. So,

1. release the port
2. close your virtual device
3. "react-native run-android" again.

How to release the port?

Long answer: it is possible!

1. Temporarily rename existing xampp folder
2. Install xampp 1.7.7 into xampp folder name
3. Folder containing just installed 1.7.7 distribution rename to different name and previously existing xampp folder rename back just to xampp.
4. In xampp folder rename php and apache folders to different names (I propose php_prev and apache_prev) so you can after switch back to them by renaming them back.
5. Copy apache and php folders from folder with xampp 1.7.7 into xampp directory

6. In xampp directory comment line apache/conf/httpd.conf:458

   #Include "conf/extra/httpd-perl.conf"

7. In xampp directory do next replaces in files:

php/pci.bat:15

from

"C:\xampp\php\.\php.exe" -f "\xampp\php\pci" -- %*

to

set XAMPPPHPDIR=C:\xampp\php "%XAMPPPHPDIR%\php.exe" -f "%XAMPPPHPDIR%\pci" -- %*

php/pciconf.bat:15

from

"C:\xampp\php\.\php.exe" -f "\xampp\php\pciconf" -- %*

to

set XAMPPPHPDIR=C:\xampp\php "%XAMPPPHPDIR%\.\php.exe" -f "%XAMPPPHPDIR%\pciconf" -- %*

Enjoy new XAMPP with PHP 5.3

Checked by myself in XAMPP 5.6.31, 7.0.15 & 7.1.1 with XAMPP Control Panel v3.2.2

i think, simply camera not initialize in first frame. Try to save image after 10 frames.

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

Create a Java archive (.jar) file using NetBeans as follows:

1. Right-click on the Project name
2. Select Properties
3. Click Packaging
4. Check Build JAR after Compiling
5. Check Compress JAR File
6. Click OK to accept changes
7. Right-click on a Project name
8. Select Build or Clean and Build

Clean and Build will first delete build artifacts (such as .class files), whereas Build will retain any existing .class files, creating new versions necessary. To elucidate, imagine a project with two classes, A and B.

When built the first time, the IDE creates A.class and B.class. Now you delete B.java but don't clear out B.class. Executing Build should leave B.class in the build directory, and bundle it into the JAR. Selecting Clean and Build will delete B.class. Since B.java was deleted, no longer will B.class be bundled.

The JAR file is built. To view it inside NetBeans:

1. Click the Files tab
2. Expand Project name >> dist

Ensure files aren't being excluded when building the JAR file.

Further to the other answers, you can also use "background". This is particularly useful when you want to set other properties relating to the way the image is used by the background, such as:

$("myObject").css("background", "transparent url('"+imageURL+"') no-repeat right top");

A scrolling comes from a box with class pre-scrollable

One can rename indexes the same way:

alter index owner.index_name rename to new_name;

Open terminal on XAMPP > go to /opt/lampp/htdocs/project_name > run php artisan migrate

DB_HOST=localhost
DB_PORT=8080
DB_DATABASE=database_name
DB_USERNAME=root

It is useful for annotating your classes, either at the method, class, or field level, something about that class that is not quite related to the class.

You could have your own annotations, used to mark certain classes as test-use only. It could simply be for documentation purposes, or you could enforce it by filtering it out during your compile of a production release candidate.

You could use annotations to store some meta data, like in a plugin framework, e.g., name of the plugin.

Its just another tool, its has many purposes.

Well a cast from myObject to byte[] is never going to work unless you've got an explicit conversion or if myObject is a byte[]. You need a serialization framework of some kind. There are plenty out there, including Protocol Buffers which is near and dear to me. It's pretty "lean and mean" in terms of both space and time.

You'll find that almost all serialization frameworks have significant restrictions on what you can serialize, however - Protocol Buffers more than some, due to being cross-platform.

If you can give more requirements, we can help you out more - but it's never going to be as simple as casting...

EDIT: Just to respond to this:

I need my binary file to contain the object's bytes. Only the bytes, no metadata whatsoever. Packed object-to-object. So I'll be implementing custom serialization.

Please bear in mind that the bytes in your objects are quite often references... so you'll need to work out what to do with them.

I suspect you'll find that designing and implementing your own custom serialization framework is harder than you imagine.

I would personally recommend that if you only need to do this for a few specific types, you don't bother trying to come up with a general serialization framework. Just implement an instance method and a static method in all the types you need:

public void WriteTo(Stream stream)
public static WhateverType ReadFrom(Stream stream)

One thing to bear in mind: everything becomes more tricky if you've got inheritance involved. Without inheritance, if you know what type you're starting with, you don't need to include any type information. Of course, there's also the matter of versioning - do you need to worry about backward and forward compatibility with different versions of your types?

I was incorrectly trying to create a default path with:

<IndexRoute component={DefaultComponent} />
<Route path="/default-path" component={DefaultComponent} />

But this creates two different paths that render the same component. Not only is this pointless, but it can cause glitches in your UI, i.e., when you are styling <Link/> elements based on this.history.isActive().

The right way to create a default route (that is not the index route) is to use <IndexRedirect/>:

<IndexRedirect to="/default-path" />
<Route path="/default-path" component={DefaultComponent} />

This is based on react-router 1.0.0. See https://github.com/rackt/react-router/blob/master/modules/IndexRedirect.js.

I added web.config to the specific folder say "Users" (VS 2015, C#) and the added following code

<?xml version="1.0"?>
 <configuration>
  <system.web>
    <authorization>     
    <deny users="?"/>
  </authorization>
</system.web>
</configuration>

Initially i used location tag but that didn't worked.

Have a look at here this link and their roadmap. They have RO|C on the way, and that can connect to their web services, which probably includes SOAP (I use the VCL version which definitely includes it).

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.

For Bootstrap 3 the default radio/button-group structure is :

<div class="btn-group" data-toggle="buttons">
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option1"> Option 1
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option2"> Option 2
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option3"> Option 3
    </label>
</div>

And you can select the active one like this:

$('.btn-primary').on('click', function(){
    alert($(this).find('input').attr('id'));
}); 

I believe the following work in version 0.11 and above. To check the version:

$ ipython --version

It may be worth adding this information to your question.

Solution:

You need to find the file ipython_notebook_config.py. Depending on your installation process this should be in somewhere like

.config/ipython/profile_default/ipython_notebook_config.py

where .config is in your home directory.

Once you have located this file find the following lines

# Subset of matplotlib rcParams that should be different for the inline backend.
# c.InlineBackend.rc = {'font.size': 10, 'figure.figsize': (6.0, 4.0), 'figure.facecolor': 'white', 'savefig.dpi': 72, 'figure.subplot.bottom': 0.125, 'figure.edgecolor': 'white'}

Uncomment this line c.InlineBack... and define your default figsize in the second dictionary entry.

Note that this could be done in a python script (and hence interactively in IPython) using

pylab.rcParams['figure.figsize'] = (10.0, 8.0)

var lbltext = document.getElementById('*spaM4').innerHTML

Btw you can also use the ui-sref attribute in your templates to pass objects

ui-sref="myState({ myParam: myObject })"

Using merge and renaming your t vector as tt (see the PS of Andrie) :

merge(tt,z,by="row.names",all.x=TRUE)[,-(5:8)]

Now if you would work with dataframes instead of matrices, this would even become a whole lot easier :

z <- as.data.frame(z)
tt <- as.data.frame(tt)
merge(tt,z["symbol"],by="row.names",all.x=TRUE)

Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.

Also based on your markup your selector is wrong. it should be #advisersDiv

Demo

function fadeIn() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
    setTimeout(fadeOut,1); //<-- Provide any delay here
};

function fadeOut() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
    setTimeout(fadeIn,1);//<-- Provide any delay here
};
fadeIn();

You can change from the property of every item.

from PIL import Image

im = Image.open('whatever.png')
width, height = im.size

According to the documentation.

I am seeing starkly different runtimes when I take a for loop in g++ 4.7.0 and using

std::vector<double> x;
std::vector<double> y;
std::vector<double> prod;

for (int i = 0; i < 5000000; i++)
{
   double r1 = ((double)rand() / double(RAND_MAX)) * 5;
   double r2 = ((double)rand() / double(RAND_MAX)) * 5;
   x.push_back(r1);
   y.push_back(r2);
}

int sz = x.size();

#pragma omp parallel for

for (int i = 0; i< sz; i++)
   prod[i] = x[i] * y[i];

the serial code (no openmp ) runs in 79 ms. the "parallel for" code runs in 29 ms. If I omit the for and use #pragma omp parallel, the runtime shoots up to 179ms, which is slower than serial code. (the machine has hw concurrency of 8)

Use an interval:

select some_date_column + interval '1' hour 
from your_table;

This may also happen if you have a slash before the folder name:

path = '/folder1/folder2'

OSError: [Errno 13] Permission denied: '/folder1'

comes up with an error but this one works fine:

path = 'folder1/folder2'

You can use the overloaded < or > operators.

For example:

DateTime d1 = new DateTime(2008, 1, 1);
DateTime d2 = new DateTime(2008, 1, 2);
if (d1 < d2) { ...

Actually the orderBy filter can take as a parameter not only a string but also a function. From the orderBy documentation: https://docs.angularjs.org/api/ng/filter/orderBy):

function: Getter function. The result of this function will be sorted using the <, =, > operator.

So, you could write your own function. For example, if you would like to compare cards based on a sum of opt1 and opt2 (I'm making this up, the point is that you can have any arbitrary function) you would write in your controller:

$scope.myValueFunction = function(card) {
   return card.values.opt1 + card.values.opt2;
};

and then, in your template:

ng-repeat="card in cards | orderBy:myValueFunction"

Here is the working jsFiddle

The other thing worth noting is that orderBy is just one example of AngularJS filters so if you need a very specific ordering behaviour you could write your own filter (although orderBy should be enough for most uses cases).

Can also do more dynamic inits with fill, e.g.

Array.fill(10){scala.util.Random.nextInt(5)} 

==>

Array[Int] = Array(0, 1, 0, 0, 3, 2, 4, 1, 4, 3)

That data:image/png;base64 URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.

Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.

Here's a trick I found to compare two branches and show how many commits each branch is ahead of the other (a more general answer on your question 1):

For local branches: git rev-list --left-right --count master...test-branch

For remote branches: git rev-list --left-right --count origin/master...origin/test-branch

This gives output like the following:

1 7

This output means: "Compared to master, test-branch is 7 commits ahead and 1 commit behind."

You can also compare local branches with remote branches, e.g. origin/master...master to find out how many commits the local master branch is ahead/behind its remote counterpart.

One thing to check that I just found is that it won't work if there are multiple elements with the same ID. It doesn't error if you try to do this, it just fails silently

it is tough if there is no data there to key off of. what are the _id field? are they mongodb object id's? If so, you could get the highest and lowest values:

lowest = db.coll.find().sort({_id:1}).limit(1).next()._id;
highest = db.coll.find().sort({_id:-1}).limit(1).next()._id;

then if you assume the id's are uniformly distributed (but they aren't, but at least it's a start):

unsigned long long L = first_8_bytes_of(lowest)
unsigned long long H = first_8_bytes_of(highest)

V = (H - L) * random_from_0_to_1();
N = L + V;
oid = N concat random_4_bytes();

randomobj = db.coll.find({_id:{$gte:oid}}).limit(1);

#define SIZE_OF_ARRAY(_array) (sizeof(_array) / sizeof(_array[0]))

Works in IE7.

You could use a label and a goto, but this is a bad hack. You should consider moving some of the stuff in your if statement to separate methods.

One another point to note down is in MaxLength attribute you can only provide max required range not a min required range. While in StringLength you can provide both.

I have tried the following config for eclipse.ini:

--launcher.XXMaxPermSize

--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6

Now eclipse performance is about 2 times faster then before.

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

The $.fn.equals(...) solution is probably the cleanest and most elegant one.

I have tried something quick and dirty like this:

JSON.stringify(a) == JSON.stringify(b)

It is probably expensive, but the comfortable thing is that it is implicitly recursive, while the elegant solution is not.

Just my 2 cents.

On my AWS beanstalk server, I don't see $_SERVER['HTTPS'] variable. I do see $_SERVER['HTTP_X_FORWARDED_PROTO'] which can be either 'http' or 'https' so if you're hosting on AWS, use this:

if ($_SERVER['HTTP_HOST'] != 'localhost' and $_SERVER['HTTP_X_FORWARDED_PROTO'] != "https") {
    $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $location);
    exit;

I suggest to use dplyr::select after dplyr::mutate. It has many helpers to select/de-select subset of columns.

In the context of this question the order by which you select will be reflected in the output data.frame.

I used a check if (!a.isFinishing()) and it seems to do what i need. a is the activity instance. Is this incorrect? Why didn't anyone try this?

To link to a UNC path from an HTML document, use file:///// (yes, that's five slashes).

file://///server/path/to/file.txt

Note that this is most useful in IE and Outlook/Word. It won't work in Chrome or Firefox, intentionally - the link will fail silently. Some words from the Mozilla team:

For security purposes, Mozilla applications block links to local files (and directories) from remote files.

And less directly, from Google:

Firefox and Chrome doesn't open "file://" links from pages that originated from outside the local machine. This is a design decision made by those browsers to improve security.

The Mozilla article includes a set of client settings you can use to override this behavior in Firefox, and there are extensions for both browsers to override this restriction.

You misspelled permission

As per official documentation link shared by Andre Kirpitch, Oracle 10g gives a maximum size of 4000 bytes or characters for varchar2. If you are using a higher version of oracle (for example Oracle 12c), you can get a maximum size upto 32767 bytes or characters for varchar2. To utilize the extended datatype feature of oracle 12, you need to start oracle in upgrade mode. Follow the below steps in command prompt:

1) Login as sysdba (sqlplus / as sysdba)

2) SHUTDOWN IMMEDIATE;

3) STARTUP UPGRADE;

4) ALTER SYSTEM SET max_string_size=extended;

5) Oracle\product\12.1.0.2\rdbms\admin\utl32k.sql

6) SHUTDOWN IMMEDIATE;

7) STARTUP;

Adding to the selected answer (as I haven't enough rep to add comment), one way to see the list of available versions (from ref) try:

One more option is to add the path of the privatekey file like this in terminal:

ssh-add "path to the privatekeyfile"

and then execute the pull command

You can grab an animated GIF of a spinning circle from Ajaxload - stick that somewhere in your website file heirarchy. Then you just need to add an HTML element with the correct code, and remove it when you're done. This is fairly simple:

function showLoadingImage() {
    $('#yourParentElement').append('<div id="loading-image"><img src="path/to/loading.gif" alt="Loading..." /></div>');
}

function hideLoadingImage() {
    $('#loading-image').remove();
}

You then just need to use these methods in your AJAX call:

$.load(
     'http://example.com/myurl',
     { 'random': 'data': 1: 2, 'dwarfs': 7},
     function (responseText, textStatus, XMLHttpRequest) {
         hideLoadingImage();
     }
);

// this will be run immediately after the AJAX call has been made,
// not when it completes.
showLoadingImage();

This has a few caveats: first of all, if you have two or more places the loading image can be shown, you're going to need to kep track of how many calls are running at once somehow, and only hide when they're all done. This can be done using a simple counter, which should work for almost all cases.

Secondly, this will only hide the loading image on a successful AJAX call. To handle the error states, you'll need to look into $.ajax, which is more complex than $.load, $.get and the like, but a lot more flexible too.

Email: {
                      group: '.col-sm-3',

                      validators: {
                          //emailAddress: {
                          //    message: 'Email not Valid'
                          //},
                          regexp: {
                              regexp: '^[^@\\s]+@([^@\\s]+\\.)+[^@\\s]+$',
                              message: 'Email not Valid'
                          },
                      }
                  },

You want set_ticks_position rather than set_label_position:

ax.xaxis.set_ticks_position('top') # the rest is the same

This gives me:

It's missing an 'int'. It should be:

const static int foo = 42;

In C and C++, it declares an integer constant with local file scope of value 42.

Why 42? If you don't already know (and it's hard to believe you don't), it's a refernce to the Answer to Life, the Universe, and Everything.

I have encountered instances where only this method works and other methods fail. Maybe it has something to do with the latest version of CMake.

Do not use any white space. I had the same issue. Then I removed white space like:

header("location:index.php"); or header('location:index.php');

Then it worked.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.

Avoid async void. Have your methods return Task instead of void. Then you can await them.

Like this:

private async Task RequestToSendOutputReport(List<byte[]> byteArrays)
{
    foreach (byte[] b in byteArrays)
    {
        while (condition)
        {
            // we'll typically execute this code many times until the condition is no longer met
            Task t = SendOutputReportViaInterruptTransfer();
            await t;
        }

        // read some data from device; we need to wait for this to return
        await RequestToGetInputReport();
    }
}

private async Task RequestToGetInputReport()
{
    // lots of code prior to this
    int bytesRead = await GetInputReportViaInterruptTransfer();
}

With the emergence of headless browsers (like phantomjs) which can emulate anything, you can't suppose that :

• spam bots do not use javascript,
• you can track mouse events to detect bot,
• they won't see that a field is visually hidden,
• they won't wait a given time before submitting.

If that used to be true, it is no longer true.

If you wan't an user friendly solution, just give them a beautiful "i am a spammer" submit button:

 <input type="submit" name="ignore" value="I am a spammer!" />
 <input type="image" name="accept" value="submit.png" alt="I am not a spammer" />

Of course you can play with two image input[type=image] buttons, changing the order after each load, the text alternatives, the content of the images (and their size) or the name of the buttons; which will require some server work.

 <input type="image" name="random125454548" value="random125454548.png"
      alt="I perfectly understand that clicking on this link will send the
      e-mail to the expected person" />
 <input type="image" name="random125452548" value="random125452548.png"
      alt="I really want to cancel the submission of this form" />

For accessibility reasons, you have to put a correct textual alternative, but I think that a long sentence is better for screenreaders users than being considered as a bot.

Additional note: those examples illustrate that understanding english (or any language), and having to make a simple choice, is harder for a spambot than : waiting 10 seconds, handling CSS or javascript, knowing that a field is hidden, emulating mouse move or emulating keyboard typing, ...

Another alternative is to use sdkman. An advantage of sdkman over brew is that many versions of gradle are supported. (brew only supports the latest version and 2.14.) To install sdkman execute:

curl -s "https://get.sdkman.io" | bash

Then follow the instructions. Go here for more installation information. Once sdkman is installed use the command:

sdk install gradle

Or to install a specific version:

sdk install gradle 2.2

Or use to use a specific installed version:

sdk use gradle 2.2

To see which versions are installed and available:

sdk list gradle

@KieranPC's solution is the correct approach for Pandas, but is not easily extendible for arbitrary attributes. For this, you can use getattr within a generator comprehension and combine using pd.concat:

# input data
list_of_dates = ['2012-12-31', '2012-12-29', '2012-12-30']
df = pd.DataFrame({'ArrivalDate': pd.to_datetime(list_of_dates)})

# define list of attributes required    
L = ['year', 'month', 'day', 'dayofweek', 'dayofyear', 'weekofyear', 'quarter']

# define generator expression of series, one for each attribute
date_gen = (getattr(df['ArrivalDate'].dt, i).rename(i) for i in L)

# concatenate results and join to original dataframe
df = df.join(pd.concat(date_gen, axis=1))

print(df)

  ArrivalDate  year  month  day  dayofweek  dayofyear  weekofyear  quarter
0  2012-12-31  2012     12   31          0        366           1        4
1  2012-12-29  2012     12   29          5        364          52        4
2  2012-12-30  2012     12   30          6        365          52        4

You could use Set.toArray() method.

Then set your $_GET variables on your first line in PHP, although this is not the desired way of setting a $_GET variable and you may experience problems depending on what you do later with that variable.

if (isset($argv[1])) {
   $_GET['variable_name'] = $argv[1];
}

the variables you launch the script with will be accessible from the $argv array in your PHP app. the first entry will the name of the script they came from, so you may want to do an array_shift($argv) to drop that first entry if you want to process a bunch of variables. Or just load into a local variable.

JavaScript doesn't have a built-in init() function, that is, it's not a part of the language. But it's not uncommon (in a lot of languages) for individual programmers to create their own init() function for initialisation stuff.

A particular init() function may be used to initialise the whole webpage, in which case it would probably be called from document.ready or onload processing, or it may be to initialise a particular type of object, or...well, you name it.

What any given init() does specifically is really up to whatever the person who wrote it needed it to do. Some types of code don't need any initialisation.

function init() {
  // initialisation stuff here
}

// elsewhere in code
init();

Try loading your javascript after.

Try this:

</form>

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

Change the window name in your two different calls:

function popitup(url,windowName) {
       newwindow=window.open(url,windowName,'height=200,width=150');
       if (window.focus) {newwindow.focus()}
       return false;

windowName must be unique when you open a new window with same url otherwise the same window will be refreshed.

You can change set orientation of linearlayout programmatically by:

I had the same problem and it got solved using

sudo easy_install cx_Oracle

but remember to unistall cx_oracle before installing it using easy_install.

Command to uninstall: pip uninstall cx_oracle

this also works, and prolly is more readable than the echo version:

printf "`date` User `whoami` started the script.\r\n" >> output.log

These two methods should save you from accidentally joining two strings that both have the delimiter in them.

    public static string Combine(string x, string y, char delimiter) {
        return $"{ x.TrimEnd(delimiter) }{ delimiter }{ y.TrimStart(delimiter) }";
    }

    public static string Combine(string[] xs, char delimiter) {
        if (xs.Length < 1) return string.Empty;
        if (xs.Length == 1) return xs[0];
        var x = Combine(xs[0], xs[1], delimiter);
        if (xs.Length == 2) return x;
        var ys = new List<string>();
        ys.Add(x);
        ys.AddRange(xs.Skip(2).ToList());
        return Combine(ys.ToArray(), delimiter);
    }

New in python 3.8, you can pass a delimiter argument to the hex function, as in this example

>>> value = b'\xf0\xf1\xf2'
>>> value.hex('-')
'f0-f1-f2'
>>> value.hex('_', 2)
'f0_f1f2'
>>> b'UUDDLRLRAB'.hex(' ', -4)
'55554444 4c524c52 4142'

If you are looking for the oldest date (minimum value), you'd sort and then take the first item returned. Sorry for the C#:

The above will return the entire object. If you just want the date returned:

var min = myData.Min( cv => cv.Date1 );

Regarding which direction to go, re: Linq to Sql vs Linq to Entities, there really isn't much choice these days. Linq to Sql is no longer being developed; Linq to Entities (Entity Framework) is the recommended path by Microsoft these days.

From Microsoft Entity Framework 4 in Action (MEAP release) by Manning Press:

What about the future of LINQ to SQL?

It's not a secret that LINQ to SQL is included in the Framework 4.0 for compatibility reasons. Microsoft has clearly stated that Entity Framework is the recommended technology for data access. In the future it will be strongly improved and tightly integrated with other technologies while LINQ to SQL will only be maintained and little evolved.

To get a commit count for a revision (HEAD, master, a commit hash):

git rev-list --count <revision>

To get the commit count across all branches:

git rev-list --all --count

I recommend against using this for build identifier, but if you must, it's probably best to use the count for the branch you're building against. That way the same revision will always have the same number. If you use the count for all branches, activity on other branches could change the number.

You can also use Bootstrap 4 flex classes

Like: .align-item-center and .justify-content-center

We can use these classes identically for all device view.

Like: .align-item-sm-center, .align-item-md-center, .justify-content-xl-center, .justify-content-lg-center, .justify-content-xs-center

.text-center class is used to align text in center.

I just coded up an offline markdown viewer using the node.js file watcher and socket.io, so you point your browser at localhost and run ./markdownviewer /path/to/README.md and it streams it to the browser using websockets.

I have also face same issue on Windows 10-64 bit OS.

When I am installed firefox on my PC its installed location is "C:\Program Files\Mozilla Firefox\firefox.exe" instead of "C:\Program Files (x86)\Mozilla Firefox", because OS is 64 bit,

So I just copy & paste "Mozilla Firefox" folder in "C:\Program Files (x86)" folder and execute selenium scripts, its work for me.

Sometimes, it's better to have only three options

 style="@android:style/TextAppearance.Small"

Use small and large to differentiate from normal screen size.

<TextView
            android:id="@+id/TextViewTopBarTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            style="@android:style/TextAppearance.Small"/>

For normal, you don't have to specify anything.

<TextView
            android:id="@+id/TextViewTopBarTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>

Using this, you can avoid testing and specifying dimensions for different screen sizes.

You can't use String.isEmpty() if it is null. Best is to have your own method to check null or empty.

public static boolean isBlankOrNull(String str) {
    return (str == null || "".equals(str.trim()));
}

I get around this problem by not having a "programming languages" section on my resume. Instead I label it simply as "languages", and I stick HTML and CSS at the end. I'd rather make life easier for the reviewer so that they can see whether mine checks-off all their requirements.

Only fools would disregard an applicant because he or she listed HTML under "languages" instead of some other label, especially since there is no industry standard. And who wants to work for fools?

Although I'm late to the party, this post is among the top results in the google search "generate load in linux".

The result marked as solution could be used to generate a system load, i'm preferring to use sha1sum /dev/zero to impose a load on a cpu-core.

The idea is to calculate a hash sum from an infinite datastream (eg. /dev/zero, /dev/urandom, ...) this process will try to max out a cpu-core until the process is aborted. To generate a load for more cores, multiple commands can be piped together.

eg. generate a 2 core load: sha1sum /dev/zero | sha1sum /dev/zero

As of iOS10 you can use

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root")!) 

to open general settings.

also you can add known urls(you can see them in the most upvoted answer) to it to open specific settings. For example the below one opens touchID and passcode.

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=TOUCHID_PASSCODE")!)

I got the same error message (Couldn't find developer disk image) after I updated my devices to iOS 9.2, but forgot to update to Xcode 7.2.

So in my case, the fix was easy: just update to Xcode 7.2 via Mac App Store.

Use data type LONGBLOB instead of BLOB in your database table.

Try this.

public static void main(String[] args) {
    EchoServer0 myServer;
    myServer = new EchoServer0();
    myServer.listen();
}

What you were trying to do was declaring a variable of type Object, not creating anything for that variable to reference, then trying to call a method that didn't exist (in the class Object) on an object that hadn't been created. It was never going to work.

public String getIMEI(Context context){

    TelephonyManager mngr = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE); 
    String imei = mngr.getDeviceId();
    return imei;

}

as docs say:

Note: object does not have a __dict__, so you can’t assign arbitrary attributes to an instance of the object class.

You could just use dummy-class instance.

       background-color:red;
       }
       </style>
   </head>

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

simple and novice :)

I think this will work.

    document.getElementById('#image').style.transform = "rotate(90deg)";

Hope this helps. It's work with me.

If you want to get the value after the hash mark or anchor as shown in a user's browser: This isn't possible with "standard" HTTP as this value is never sent to the server (hence it won't be available in $_SERVER["REQUEST_URI"] or similar predefined variables). You would need some sort of JavaScript magic on the client side, e.g. to include this value as a POST parameter.

If it's only about parsing a known URL from whatever source, the answer by mck89 is perfectly fine though.

I had this issue with Dialogs based on an extended DialogFragment which worked fine on devices running API 26 but failed with API 23. The above strategies didn't work but I resolved the issue by removing the onCreateView method (which had been added by a more recent Android Studio template) from the DialogFragment and creating the dialog in onCreateDialog.

The solution only solves part of the problem, it may let you style the container and contents but doesn't let you change the titlebar. I developed a workaround of sorts but adding an id to the dialog div, then using jQuery .prev to change the style of the div which is the previous sibling of the dialog's div. This works because when jQueryUI creates the dialog, your original div becomes a sibling of the new container, but the title div is a the immediately previous sibling to your original div but neither the container not the title div has an id to simplify selecting the div.

HTML

<button id="dialog1" class="btn btn-danger">Warning</button>
<div title="Nothing here, really" id="nonmodal1">
  Nothing here
</div>

You can use CSS to style the main section of the dialog but not the title

.custom-ui-widget-header-warning {
  background: #EBCCCC;
  font-size: 1em;
}

You need some JS to style the title

$(function() {
                   $("#nonmodal1").dialog({
                     minWidth: 400,
                     minHeight: 'auto',
                     autoOpen: false,
                     dialogClass: 'custom-ui-widget-header-warning',
                     position: {
                       my: 'center',
                       at: 'left'
                     }
                   });

                   $("#dialog1").click(function() {
                     if ($("#nonmodal1").dialog("isOpen") === true) {
                       $("#nonmodal1").dialog("close");
                     } else {
                       $("#nonmodal1").dialog("open").prev().css('background','#D9534F');

                     }
                   });
    });

The example only shows simple styling (background) but you can make it as complex as you wish.

You can see it in action here:

http://codepen.io/chris-hore/pen/OVMPay

<html>
    <head>
        <script>
        function callme(field) {
            alert("field:" + field.value);
        }
        </script>
    </head>
    <body>
        <form name="f1">
            <input type="text" onkeyup="callme(this);" name="text1">
        </form>
    </body>
</html>

It looks like you can use the onkeyup to get the new value of the HTML input control. Hope it helps.

As an alternative, if you put a space between the date and time, DateTime.Parse will recognize the format for you. That's about as simple as you can get it. (If ParseExact was still not being recognized)

You can use convert from hablar to change a column of the data frame quickly.

library(tidyverse)
library(hablar)

x <- tibble(var = c(1.34, 4.45, 6.98))

x %>% 
  convert(int(var))

gives you:

# A tibble: 3 x 1
    var
  <int>
1     1
2     4
3     6

That's something controlled by your terminal, not by printf.

printf simply sends a \t to the output stream (which can be a tty, a file etc), it doesn't send a number of spaces.

create table like this,

CommentId    UserId
---------------------
   1            usr1
   1            usr2

In this way you can check whether the user posted the comments are not.. Apart from this there should be tables for Comments and Users with respective id's

You don't need to apply to_date() to sysdate. It is already there:

select 1
from dual 
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');

If you are concerned about the time component on the date, then use trunc():

select 1
from dual 
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
                             TO_DATE('20/06/2014', 'DD/MM/YYYY');

Add a second step to your registration process. First page as usual, but on reload, display a second page and ask the email again. If it's that important, the user can handle it.

#include <iostream>
#include <sstream>
#include <iterator>
#include <string>

using namespace std;

template <size_t N>
void splitString(string (&arr)[N], string str)
{
    int n = 0;
    istringstream iss(str);
    for (auto it = istream_iterator<string>(iss); it != istream_iterator<string>() && n < N; ++it, ++n)
        arr[n] = *it;
}

int main()
{
    string line = "test one two three.";
    string arr[4];

    splitString(arr, line);

    for (int i = 0; i < 4; i++)
       cout << arr[i] << endl;
}

in overloading function with same name having different parameters whereas in overridding function having same name as well as same parameters replace the base class to the derived class (inherited class)

Sometimes the value needs to be trimmed of whitespace or it won't be matched, in such case this additional step can be used (source):

if(((DropDownList) myControl1).Items.Cast<ListItem>().Select(i => i.Value.Trim() == ctrl.value.Trim()).FirstOrDefault() != null){}

If there is only 1 occurrence, the answer of ivanovic is the best way I guess. But if there are many occurrences, you should use regexp:

\[(.*?)\] this is your pattern. And in each group(1) will get you your string.

Pattern p = Pattern.compile("\\[(.*?)\\]");
Matcher m = p.matcher(input);
while(m.find())
{
    m.group(1); //is your string. do what you want
}

Following on from LES2's answer, you can eliminate some repetition in the efficient version, by calling the overloaded function:

public static <T> T coalesce(T a, T b) {
    return a != null ? a : b;
}
public static <T> T coalesce(T a, T b, T c) {
    return a != null ? a : coalesce(b,c);
}
public static <T> T coalesce(T a, T b, T c, T d) {
    return a != null ? a : coalesce(b,c,d);
}
public static <T> T coalesce(T a, T b, T c, T d, T e) {
    return a != null ? a : coalesce(b,c,d,e);
}

Using "groupby" and list comprehension:

Storing all the split dataframe in list variable and accessing each of the seprated dataframe by their index.

DF = pd.DataFrame({'chr':["chr3","chr3","chr7","chr6","chr1"],'pos':[10,20,30,40,50],})
ans = [pd.DataFrame(y) for x, y in DF.groupby('chr', as_index=False)]

accessing the separated DF like this:

ans[0]
ans[1]
ans[len(ans)-1] # this is the last separated DF

accessing the column value of the separated DF like this:

ansI_chr=ans[i].chr 

Press Ctrl + H, should bring up the search that will include options to search via project, directory, etc.

Ctrl + Alt + G can be used to find selected text across a workspace in eclipse.

My guess is that the directory ~/bin/sbt/bin is not in your PATH.

To execute programs or scripts that are in the current directory you need to prefix the command with ./, as in:

./sbt

This is a security feature in linux, so to prevent overriding of system commands (and other programs) by a malicious party dropping a file in your home directory (for example). Imagine a script called 'ls' that emails your /etc/passwd file to 3rd party before executing the ls command... Or one that executes 'rm -rf .'...

That said, unless you need something specific from the latest source code, you're best off doing what paradigmatic said in his post, and install it from the Typesafe repository.

With .split:

var arr = str.split( /(?<=^(?:.{3})+)(?!$)/ )  // [ 'abc', 'def', 'ghi', 'jkl' ]

and .replace will be:

var replaced = str.replace( /(?<=^(.{3})+)(?!$)/g, ' || ' )  // 'abc || def || ghi || jkl'

/(?!$)/ is to to stop before end/$/, without is:

var arr      = str.split( /(?<=^(?:.{3})+)/ )        // [ 'abc', 'def', 'ghi', 'jkl' ]     // I don't know why is not [ 'abc', 'def', 'ghi', 'jkl' , '' ], comment?
var replaced = str.replace( /(?<=^(.{3})+)/g, ' || ')  // 'abc || def || ghi || jkl || '

ignoring group /(?:...)/ is no need in .replace but in .split is adding groups to arr:

var arr = str.split( /(?<=^(.{3})+)(?!$)/ )  // [ 'abc', 'abc', 'def', 'abc', 'ghi', 'abc', 'jkl' ]

I just finished a .net library with a few useful queries that return strongly typed C# objects for code gen/ t4 templates.

Foreign Key Metadata

My usual way of doing this is:

my %unique = ();
foreach my $item (@myarray)
{
    $unique{$item} ++;
}
my @myuniquearray = keys %unique;

If you use a hash and add the items to the hash. You also have the bonus of knowing how many times each item appears in the list.

in iterm2

fn + leftArraw or fn + rightArrow

this worked for me

Try the following simple one-liners:

For all UNIX/OSX/Linux

dir=$(cd -P -- "$(dirname -- "$0")" && pwd -P)

Bash

dir=$(cd -P -- "$(dirname -- "${BASH_SOURCE[0]}")" && pwd -P)

^{Note: A double dash (--) is used in commands to signify the end of command options, so files containing dashes or other special characters won't break the command.}

^{Note: In Bash, use ${BASH_SOURCE[0]} in favor of $0, otherwise the path can break when sourcing it (source/.).}

For Linux, Mac and other *BSD:

cd "$(dirname "$(realpath "$0")")";

^{Note: realpath should be installed in the most popular Linux distribution by default (like Ubuntu), but in some it can be missing, so you have to install it.}

^{Note: If you're using Bash, use ${BASH_SOURCE[0]} in favor of $0, otherwise the path can break when sourcing it (source/.).}

Otherwise you could try something like that (it will use the first existing tool):

cd "$(dirname "$(readlink -f "$0" || realpath "$0")")"

For Linux specific:

cd "$(dirname "$(readlink -f "$0")")"

Using GNU readlink on *BSD/Mac:

cd "$(dirname "$(greadlink -f "$0")")"

Note: You need to have coreutils installed (e.g. 1. Install Homebrew, 2. brew install coreutils).

In bash you can use Parameter Expansions to achieve that, like:

cd "${0%/*}"

but it doesn't work if the script is run from the same directory.

Alternatively you can define the following function in bash:

realpath () {
  [[ $1 = /* ]] && echo "$1" || echo "$PWD/${1#./}"
}

^{This function takes 1 argument. If argument has already absolute path, print it as it is, otherwise print $PWD variable + filename argument (without ./ prefix).}

or here is the version taken from Debian .bashrc file:

function realpath()
{
    f=$@
    if [ -d "$f" ]; then
        base=""
        dir="$f"
    else
        base="/$(basename "$f")"
        dir=$(dirname "$f")
    fi
    dir=$(cd "$dir" && /bin/pwd)
    echo "$dir$base"
}

Its very Simple,

1. Close visual studio (Having Solution)(Remember Configuration and Solution type and start up project)
2. Go to solution path
3. Delete SolutionName.suo
4. Open Solution again
5. set Configuration and Solution type and start up project (if it is changed)
6. Build and check

Reason why it happend In my case i have changed the references of some project

This is probably not recommended.

I figured out a workaround which works if your div doesn't contain text and has an uniform background.

display: 'list-item'

gives the div the desired height and width, but with the big downside of having a list item bullet. Since the div has a homogeneous background-color I got rid of the bullet with those styles:

list-style-position: 'inside',
color: *background-color*,

There are two kinds of cascades in Doctrine:

1) ORM level - uses cascade={"remove"} in the association - this is a calculation that is done in the UnitOfWork and does not affect the database structure. When you remove an object, the UnitOfWork will iterate over all objects in the association and remove them.

2) Database level - uses onDelete="CASCADE" on the association's joinColumn - this will add On Delete Cascade to the foreign key column in the database:

@ORM\JoinColumn(name="father_id", referencedColumnName="id", onDelete="CASCADE")

I also want to point out that the way you have your cascade={"remove"} right now, if you delete a Child object, this cascade will remove the Parent object. Clearly not what you want.

Simple: e.g. if div id 'mydiv'

jQuery.fancybox.open({href: "#mydiv"});

This also makes JS code functional which is inside div.

                        // Think about {5,5,4}
                    if(arr[i]>sec_high && arr[i]<highest || highest==sec_high)

Although the ffile:////.exe used to work (for example - some versions of early html 4) it appears html 5 disallows this. Tested using the following:

<a href="ffile:///<path name>/<filename>.exe" TestLink /a> 
<a href="ffile://<path name>/<filename>.exe" TestLink /a> 
<a href="ffile:/<path name>/<filename>.exe" TestLink /a> 
<a href="ffile:<path name>/<filename>.exe" TestLink /a> 
<a href="ffile://///<path name>/<filename>.exe" TestLink /a> 
<a href="file://<path name>/<filename>.exe" TestLink /a> 
<a href="file:/<path name>/<filename>.exe" TestLink /a> 
<a href="file:<path name>/<filename>.exe" TestLink /a> 
<a href="ffile://///<path name>/<filename>.exe" TestLink /a>

as well as ... 1/ substituted the "ffile" with just "file" 2/ all the above variations with the http:// prefixed before the ffile or file.

The best I could see was there is a possibility that if one wanted to open (edit) or save the file, it could be accomplished. However, the exec file would not execute otherwise.

Simple & Easy answer,

The %2C means , comma in URL. when you add the String "abc,defg" in the url as parameter then that comma in the string which is abc , defg is changed to abc%2Cdefg .There is no need to worry about it.

FYI

Using netbeans New Entity Classes from Database with a mysql *auto_increment* column, creates you an attribute with the following annotations:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "id")
@NotNull
private Integer id;

This was getting me the same an error saying the column must not be null, so i simply removed the @NotNull anotation leaving the attribute null, and it works!

INSERT INTO [DatabaseName1].dbo.[TableName1] SELECT * FROM [DatabaseName2].dbo.[TableName2]
 WHERE [YourPK] not in (select [YourPK] from [DatabaseName1].dbo.[TableName1])

One way is to use functor:

 template <class T1, class T2>
    class CopyMapToVec
    {
    public: 
        CopyMapToVec(std::vector<T2>& aVec): mVec(aVec){}

        bool operator () (const std::pair<T1,T2>& mapVal) const
        {
            mVec.push_back(mapVal.second);
            return true;
        }
    private:
        std::vector<T2>& mVec;
    };


int main()
{
    std::map<std::string, int> myMap;
    myMap["test1"] = 1;
    myMap["test2"] = 2;

    std::vector<int>  myVector;

    //reserve the memory for vector
    myVector.reserve(myMap.size());
    //create the functor
    CopyMapToVec<std::string, int> aConverter(myVector);

    //call the functor
    std::for_each(myMap.begin(), myMap.end(), aConverter);
}

If you're comfortable with numba it allows to create a fast short-circuit (stops as soon as a NaN is found) function:

import numba as nb
import math

@nb.njit
def anynan(array):
    array = array.ravel()
    for i in range(array.size):
        if math.isnan(array[i]):
            return True
    return False

If there is no NaN the function might actually be slower than np.min, I think that's because np.min uses multiprocessing for large arrays:

import numpy as np
array = np.random.random(2000000)

%timeit anynan(array)          # 100 loops, best of 3: 2.21 ms per loop
%timeit np.isnan(array.sum())  # 100 loops, best of 3: 4.45 ms per loop
%timeit np.isnan(array.min())  # 1000 loops, best of 3: 1.64 ms per loop

But in case there is a NaN in the array, especially if it's position is at low indices, then it's much faster:

array = np.random.random(2000000)
array[100] = np.nan

%timeit anynan(array)          # 1000000 loops, best of 3: 1.93 µs per loop
%timeit np.isnan(array.sum())  # 100 loops, best of 3: 4.57 ms per loop
%timeit np.isnan(array.min())  # 1000 loops, best of 3: 1.65 ms per loop

Similar results may be achieved with Cython or a C extension, these are a bit more complicated (or easily avaiable as bottleneck.anynan) but ultimatly do the same as my anynan function.

Just verified this today, but if you are trying to open a Facebook page, you can use "fb://page/{Page ID}"

Page ID can be found under your page in the about section near the bottom.

Specific to my use case, in Xamarin.Forms, you can use this snippet to open in the app if available, otherwise in the browser.

Device.OpenUri(new Uri("fb://page/{id}"));

See: http://docs.oracle.com/javase/tutorial/essential/io/pathOps.html

Using java.nio.file.Path and java.nio.file.Paths, you can do the following to show what Java thinks is your current path. This for 7 and on, and uses NIO.

Path currentRelativePath = Paths.get("");
String s = currentRelativePath.toAbsolutePath().toString();
System.out.println("Current relative path is: " + s);

This outputs Current relative path is: /Users/george/NetBeansProjects/Tutorials that in my case is where I ran the class from. Constructing paths in a relative way, by not using a leading separator to indicate you are constructing an absolute path, will use this relative path as the starting point.

Be careful when iterating over arrays!!

It is a common misconception that using the index of the element in the array is an acceptable way of suppressing the error you are probably familiar with:

Each child in an array should have a unique "key" prop.

However, in many cases it is not! This is anti-pattern that can in some situations lead to unwanted behavior.

Understanding the key prop

React uses the key prop to understand the component-to-DOM Element relation, which is then used for the reconciliation process. It is therefore very important that the key always remains unique, otherwise there is a good chance React will mix up the elements and mutate the incorrect one. It is also important that these keys remain static throughout all re-renders in order to maintain best performance.

That being said, one does not always need to apply the above, provided it is known that the array is completely static. However, applying best practices is encouraged whenever possible.

A React developer said in this GitHub issue:

• key is not really about performance, it's more about identity (which in turn leads to better performance). randomly assigned and changing values are not identity
• We can't realistically provide keys [automatically] without knowing how your data is modeled. I would suggest maybe using some sort of hashing function if you don't have ids
• We already have internal keys when we use arrays, but they are the index in the array. When you insert a new element, those keys are wrong.

In short, a key should be:

• Unique - A key cannot be identical to that of a sibling component.
• Static - A key should not ever change between renders.

Using the key prop

As per the explanation above, carefully study the following samples and try to implement, when possible, the recommended approach.

Bad (Potentially)

<tbody>
    {rows.map((row, i) => {
        return <ObjectRow key={i} />;
    })}
</tbody>

This is arguably the most common mistake seen when iterating over an array in React. This approach isn't technically "wrong", it's just... "dangerous" if you don't know what you are doing. If you are iterating through a static array then this is a perfectly valid approach (e.g. an array of links in your navigation menu). However, if you are adding, removing, reordering or filtering items, then you need to be careful. Take a look at this detailed explanation in the official documentation.

class MyApp extends React.Component {
  constructor() {
    super();
    this.state = {
      arr: ["Item 1"]
    }
  }
  
  click = () => {
    this.setState({
      arr: ['Item ' + (this.state.arr.length+1)].concat(this.state.arr),
    });
  }
  
  render() {
    return(
      <div>
        <button onClick={this.click}>Add</button>
        <ul>
          {this.state.arr.map(
            (item, i) => <Item key={i} text={"Item " + i}>{item + " "}</Item>
          )}
        </ul>
      </div>
    );
  }
}

const Item = (props) => {
  return (
    <li>
      <label>{props.children}</label>
      <input value={props.text} />
    </li>
  );
}

ReactDOM.render(<MyApp />, document.getElementById("app"));

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="app"></div>

In this snippet we are using a non-static array and we are not restricting ourselves to using it as a stack. This is an unsafe approach (you'll see why). Note how as we add items to the beginning of the array (basically unshift), the value for each <input> remains in place. Why? Because the key doesn't uniquely identify each item.

In other words, at first Item 1 has key={0}. When we add the second item, the top item becomes Item 2, followed by Item 1 as the second item. However, now Item 1 has key={1} and not key={0} anymore. Instead, Item 2 now has key={0}!!

As such, React thinks the <input> elements have not changed, because the Item with key 0 is always at the top!

So why is this approach only sometimes bad?

This approach is only risky if the array is somehow filtered, rearranged, or items are added/removed. If it is always static, then it's perfectly safe to use. For example, a navigation menu like ["Home", "Products", "Contact us"] can safely be iterated through with this method because you'll probably never add new links or rearrange them.

In short, here's when you can safely use the index as key:

• The array is static and will never change.
• The array is never filtered (display a subset of the array).
• The array is never reordered.
• The array is used as a stack or LIFO (last in, first out). In other words, adding can only be done at the end of the array (i.e push), and only the last item can ever be removed (i.e pop).

Had we instead, in the snippet above, pushed the added item to the end of the array, the order for each existing item would always be correct.

Very bad

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={Math.random()} />;
    })}
</tbody>

While this approach will probably guarantee uniqueness of the keys, it will always force react to re-render each item in the list, even when this is not required. This a very bad solution as it greatly impacts performance. Not to mention that one cannot exclude the possibility of a key collision in the event that Math.random() produces the same number twice.

Unstable keys (like those produced by Math.random()) will cause many component instances and DOM nodes to be unnecessarily recreated, which can cause performance degradation and lost state in child components.

Very good

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={row.uniqueId} />;
    })}
</tbody>

This is arguably the best approach because it uses a property that is unique for each item in the dataset. For example, if rows contains data fetched from a database, one could use the table's Primary Key (which typically is an auto-incrementing number).

The best way to pick a key is to use a string that uniquely identifies a list item among its siblings. Most often you would use IDs from your data as keys

Good

componentWillMount() {
  let rows = this.props.rows.map(item => { 
    return {uid: SomeLibrary.generateUniqueID(), value: item};
  });
}

...

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={row.uid} />;
    })}
</tbody>

This is also a good approach. If your dataset does not contain any data that guarantees uniqueness (e.g. an array of arbitrary numbers), there is a chance of a key collision. In such cases, it is best to manually generate a unique identifier for each item in the dataset before iterating over it. Preferably when mounting the component or when the dataset is received (e.g. from props or from an async API call), in order to do this only once, and not each time the component re-renders. There are already a handful of libraries out there that can provide you such keys. Here is one example: react-key-index.

Sounds like a good job for regular expressions.

Laravel validation rules support regular expressions. Both 4.X and 5.X versions are supporting it :

• 4.2 : http://laravel.com/docs/4.2/validation#rule-regex
• 5.1 : http://laravel.com/docs/5.1/validation#rule-regex

This might help too:

I believe that was already answered here.

String versionName = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;

OR

int versionCode = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;

sort -u will be slightly faster, because it does not need to pipe the output between two commands

also see my question on the topic: calling uniq and sort in different orders in shell

To search the commit log (across all branches) for the given text:

git log --all --grep='Build 0051'

To search the actual content of commits through a repo's history, use:

git grep 'Build 0051' $(git rev-list --all)

to show all instances of the given text, the containing file name, and the commit sha1.

Finally, as a last resort in case your commit is dangling and not connected to history at all, you can search the reflog itself with the -g flag (short for --walk-reflogs:

git log -g --grep='Build 0051'

EDIT: if you seem to have lost your history, check the reflog as your safety net. Look for Build 0051 in one of the commits listed by

git reflog

You may have simply set your HEAD to a part of history in which the 'Build 0051' commit is not visible, or you may have actually blown it away. The git-ready reflog article may be of help.

To recover your commit from the reflog: do a git checkout of the commit you found (and optionally make a new branch or tag of it for reference)

git checkout 77b1f718d19e5cf46e2fab8405a9a0859c9c2889
# alternative, using reflog (see git-ready link provided)
# git checkout HEAD@{10}
git checkout -b build_0051 # make a new branch with the build_0051 as the tip

Use this line given below instead of header() function.

echo "<script>window.top.location = 'https://apps.facebook.com/yourappnamespace/';</script>";

You could declare one or more of your targets to be phony.

A phony target is one that is not really the name of a file; rather it is just a name for a recipe to be executed when you make an explicit request. There are two reasons to use a phony target: to avoid a conflict with a file of the same name, and to improve performance.

...

A phony target should not be a prerequisite of a real target file; if it is, its recipe will be run every time make goes to update that file. As long as a phony target is never a prerequisite of a real target, the phony target recipe will be executed only when the phony target is a specified goal

Assuming your categories are in cells A1:A6 and the corresponding values are in B1:B6, you might try typing the formula =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) in another cell and then pressing CTRL+SHIFT+ENTER.

Using CTRL+SHIFT+ENTER tells Excel to treat the formula as an "array formula". In this example, that means that the IF statement returns an array of 6 values (one of each of the cells in the range $A$1:$A$6) instead of a single value. The MEDIAN function then returns the median of these values. See http://www.cpearson.com/excel/arrayformulas.aspx for a similar example using AVERAGE instead of MEDIAN.

Set the PATH variable, like you're doing. If you're running the program from the IDE, you can modify environment variables by adjusting the Debugging options in the project properties.

If the DLLs are named such that you don't need different paths for the different configuration types, you can add the path to the system PATH variable or to Visual Studio's global one in Tools | Options.

This is a lot simpler with .slideToggle():

Here is a great article on Common Design Patterns for Android:

Creational patterns:

• Builder (e.g. AlertDialog.Builder)
• Dependency Injection (e.g. Dagger 2)
• Singleton

Structural patterns:

• Adapter (e.g. RecyclerView.Adapter)
• Facade (e.g. Retrofit)

Behavioral patterns:

• Command (e.g. EventBus)
• Observer (e.g. RxAndroid)
• Model View Controller
• Model View ViewModel (similar to the MVC pattern above)

public static string ComputeSHA256Hash(string text)
{
    using (var sha256 = new SHA256Managed())
    {
        return BitConverter.ToString(sha256.ComputeHash(Encoding.UTF8.GetBytes(text))).Replace("-", "");
    }

The reason why you get different results is because you don't use the same string encoding. The link you put for the on-line web site that computes SHA256 uses UTF8 Encoding, while in your example you used Unicode Encoding. They are two different encodings, so you don't get the same result. With the example above you get the same SHA256 hash of the linked web site. You need to use the same encoding also in PHP.

The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

Using jQuery, here's an Array unique function I made:

Array.prototype.unique = function () {
    var arr = this;
    return $.grep(arr, function (v, i) {
        return $.inArray(v, arr) === i;
    });
}

console.log([1,2,3,1,2,3].unique()); // [1,2,3]

Literal strings are unicode by default in Python3.

Assuming that text is a bytes object, just use text.decode('utf-8')

unicode of Python2 is equivalent to str in Python3, so you can also write:

str(text, 'utf-8')

if you prefer.

I was looking for a solution to add an UIImage to my UIButton. The problem was just it displays the image bigger than needed. Just helped me with this:

_imageViewBackground = [[UIImageView alloc] initWithFrame:rectImageView];
_imageViewBackground.image = [UIImage imageNamed:@"gradientBackgroundPlain"];
[self addSubview:_imageViewBackground];
[self insertSubview:_imageViewBackground belowSubview:self.label];
_imageViewBackground.hidden = YES;

Every time I want to display my UIImageView I just set the var hidden to YES or NO. There might be other solutions but I got confused so many times with this stuff and this solved it and I didn't need to deal with internal stuff UIButton is doing in background.

both for and class are reserved words in JavaScript this is why when it comes to HTML attributes in JSX you need to use something else, React team decided to use htmlFor and className respectively

WHERE `column` LIKE '%$needle%'

I had the same thing happen to a PNG with transparency that was set as the background-image of an <A> element with opacity applied.

The fix was to set the background-color of the <A> element.

So, the following:

filter: alpha(opacity=40);
-moz-opacity: 0.4;
-khtml-opacity: 0.4;
opacity: 0.4;
background-image: ...;

Turns into:

/* "Overwritten" by the background-image. However this fixes the IE7 and IE8 PNG-transparency-plus-opacity bug. */
background-color: #FFFFFF; 

filter: alpha(opacity=40);
-moz-opacity: 0.4;
-khtml-opacity: 0.4;
opacity: 0.4;
background-image: ...;

The top voted answer does not work for MacOS so for those on a mac, I've successfully tested this:

GATEWAY=`route -n get default | grep gateway`
if [ -z "$GATEWAY" ]
  then
    echo error
else
  ping -q -t 1 -c 1 `echo $GATEWAY | cut -d ':' -f 2` > /dev/null && echo ok || echo error
fi

tested on MacOS High Sierra 10.12.6

#if DEBUG
bool bypassCheck=TRUE_OR_FALSE;//i will decide depending on what i am debugging

bool bypassCheck = false; //NEVER bypass it
#endif

Make sure you have the checkbox to define DEBUG checked in your build properties.
